Develop's CI after the a18bbe5 pin (run 41522001173) fails 14 tests that
passed on f916a8d, and passes two listed ones. Each new line says what the
test sees on v1.1.0-alpha; v1.1.0-alpha.1 fixes the setback hole's cause.

On SMLib v1.1.0-alpha, 06/018 makes 597 or 594 edges from the same input:
the union's post-process keeps pointers to edges it has deleted. A golden
entry's `unstable` reason makes the gate compare that case's status only
and name it in its output; recording keeps the reason, and only an edit of
the golden removes it. v1.1.0-alpha.1 fixes the cause and removes the mark.

Fixed (off the known-failing list): the Mixed corner's peg cases and the concave arc with the front top edge (smlib #123), and the 40° boss junction (smlib #124). Eight cases in all.
New failures, recorded as they are, each with its reason. They passed on f916a8d.
- **Six cases grade a blend seam G0 where G1 (or G2) is wanted,** at the end of the round's contact seam, after smlib #124's End at a smooth vertex. Two of them also shift in volume.
- **Four cases come back unsupported** after smlib #125, which leaves setbacks to the Setback's corners only.
- **Ladder 07/012** makes 9 faces, 20 edges and 13 vertices, where its golden had 8, 18 and 12. Its golden entry is the new result, with the reason added.
Whether each change is by design or a defect is being established. A defect is fixed in solidcore, where the End and the Setback are being brought over (#2364, #2365), not in the frozen SMLib.

- #122: tests gated on counts;
- #123: the Mixed corner;
- #124: the End at a smooth vertex;
- #125: four or more rounds, and open setbacks;

SMLib's flat arrays now carry the corner of three equal rounds as `SURFACE_BALL_PATCH` (kind 6): its net as a NURBS face's block, with its sphere's centre and radius as its definition (ids 36 and 166). The record reads it as `ball_patch {center, radius}`, a label like the analytic kinds, with the net as its `nurbs`. A plain sphere with a form won't do: the net is not a piece of SMLib's sphere NURBS, so SMLib's `IsNurbSurfaceSphere` would refuse it.
Written back, a ball patch is kind 6 with the same definition, which SMLib takes once its net is certified on that sphere. Elsewhere:
- Offsets classify it as its sphere, so its offsets stay exact and collapse at the centre.
- Face kinds count it as a sphere: fillet_three_edges_at_a_corner's corner is now `sphere`, no longer `other`.
- STEP, which has no ball-patch entity, gets the net as the face's B-spline surface, pcurves included.
- Iso curves and SSI of the label are refused; the face's form is what evaluates.
Test: a_rounded_cubes_ball_patches_go_round_with_their_spheres. The cube's eight corners are ball patches about the corners pulled in by r. Points of each patch lie on its sphere to 1e-12. The patches are kind 6 again after import, with the same definitions bit for bit, and the closed-form volume holds.
Format: pending/ball-patch-faces.rs. Docs: docs/native-brep.md and the rig README's `surface_types` (`ball_patch`).

Each round runs whole to its section square to its edge at its setback (the owner's rule, at
least 1.5 r, scaled to the least at which the G1 fill is certified convex), and the hole is the
setback split: one patch per round and the triangle in three quadrilaterals, 15 faces, G1.
Outside the box the sections span the body is the three strips', so its volume is theirs within
that box's. A later r3 round at the mitred corner makes the body all three at once make
(7928.142563938, 15 faces), as the engine and the model-cache tests have it.

SMLib's setback corner takes a G1 fill only once certified convex, and refuses a setback too
short for that as SMLIB_ERR_NO_ROOM with SMLIB_FIT_SETBACK_AT_LEAST, the smallest setback that
builds. The kernel reads it (solidcraft-smlib binds smlib_blend_fit_size) and names it; the
Fillet dialog says it in plain words. Other room refusals keep their words. The r5 box corner
set back 5.5 is refused naming 5.962, which builds.

The round's cylinder keeps the frame it was made on when it is turned (SMLib's SwapUV no longer

SMLib's Ball corner is always the rational patch exactly on the sphere (owner ruling, blend
design §23), so the corner counts as an 'other' face beside the three cylinders and six planes.
The removed volume still checks the corner against r³ − πr³/6.

With the tangent chain on, 016's and 018's r3 runs on along the r5 round's end arc and down the
vertical edge, so the third pick (60, 40, 8) is 3 from both of that round's contact lines and
names no edge: refused, asking for a point along one edge. The corners they were made for are
020 and 021 (the r3 alone), whose golden entries are 016's and 018's (021 measured on f12a101).

851-fillet-arc-then-top-front and 851-fillet-top-front-then-upright: with the tangent chain on,
each R2 chain runs along the end curve of an R2 round on a curved face (the arc round's end on the
front face; the first round's end on the wall), where the rolling ball sits on that round's own
centre line, so the piece is the ball about (39.2538, -19, 8): the three-edge rolling-ball corner.

- every-fillet-after-fillet-curvature-front-then-side-r3: the side edge's chain runs round the
first curvature round's end curve, whose radius of curvature has a weighted mean of 3 (its
setback) and is unbounded at the ends, so somewhere below 3: the size-3 blend's contact line
folds back on itself. Refused, "larger than the faces beside its edges allow", as ladder
07-fillets/016's r7 on the r5 arc. (It was solid or refused for running on tangentially.)
- every-block-cylinder-tangent-concave-arc-r2-no-tangent-chain: the chain takes every piece of
the half circle and ends at the convex edges it runs on into; it builds the analytic 19091.9620,
so the outcome is solid (the refusal alternative was the chain-off one's).

With the tangent chain on, two cases round more than the edge they pick, and their old
expectations were the single edge's:
- 1207-fillet-box-end-edge-into-unblended-round: the r1 chain is the end face's top edge, the r3
round's end arc and the back upright; 34 A + (pi/2) A (3 - c) by Pappus on the arc:
V = 7953.139216 (it built 7953.139216, the old 7957.505 passed only inside 1e-3), 10 faces.
- 851-fillet-top-front-then-front-left-upright: the upright's chain runs up the first round's
end arc on x = 0 and along the left top edge, so the corner becomes the R2 ball's eighth:
V0 less the first round's spandrel to the wall (35.344727) less 27 (4 - pi) + 2 pi/3:
V = 9530.777979 (built 9530.777987), 10 faces.

Where a case's point is one edge of a tangent chain rounded alone, a copy keeps tangent_chain
false as its own case (SMLib rounds exactly the picked edges, ending at the smooth vertex); their
expectations stay as they were, to be re-derived:
- fillets/1207-fillet-box-end-edge-into-unblended-round-partial-chain;
- fillets/every-fillet-after-fillet-curvature-front-then-side-r3-partial-chain;
- fillets/1207-fillet-bar-top-edge-after-boss-arc-round-partial-chain, renamed from
...-no-tangent-chain: with the chain on it is exactly 1207-fillet-bar-top-edge-after-boss-arc-round,

The owner's ruling of 2026-11-01: the rig and the ladder round with tangent_chain true, how a

SMLib builds a variable round's law corners as its balls' union (the corner
ball's zone at a dip, the sides' crossing at a peak): the kernel's corner
through a middle point (39.5410) and the crate's 4 -> 2 -> 4 law (39.5421) pass.

A variable round is the envelope of the balls rolled along the edge, which takes less than a
quarter round in each section. The expectations are now that union, the law continued past the
edge's ends along its end slopes, integrated by Gauss-Legendre panels in x and t; 2, 4 and 8
panels agree to 1e-9 of the body's values, and 77's removed volume matches a brute-force union of
balls to 2.5e-10. The nearest-ball search now scans the balls the ray meets around ball x
(|x - s| < r(s) sqrt(sin 2t)) on their own, which near the faces and where 78's radius closes to 0
are narrower than the global scan's step. Regenerating keeps each case's known_failure. 79, a
constant radius, is unchanged.

Eight fillet cases for the blend's cross-section by its order of contact with the faces, each
graded on its analytic volume at rel 1e-7 and its exact continuity (the order, and not the next):
- a box's top back edge chamfered 3 (G0), rounded r3 (G1) and curvature-rounded 3 (G2): the
areas cut off the corner s^2/2, (1 - pi/4) s^2 and 113/756 s^2, the last by the default
thumbweight's definition;
- a pipe R10 dipping into a plate, its concave edge chamfered 2 (the chord between the contacts of
the ball SMLib rolls for that setback, radius 1), rounded r2 and curvature-rounded 2, each
section's added area by Green's theorem along the plate, the section and the pipe's arc; the
order-2 section is built from the faces' feet of the point at distance d from both, which on
the pipe are not linear in d;
- a boss root curvature-rounded 2, the square corner's section revolved (Pappus);
- a variable round r1 to r5 along a box edge (rel 1e-5): the balls' envelope is a circular cone,
and the volume is the cone's sections integrated along the edge.
Three fail today and are listed: the two curvature rounds whose faces are not a square corner of
planes (SMLib's quintic blend curve, not the order-2 section: rel 6.5e-7 and 1.2e-5) and the

The six corner cases added in 3a854104a took the fillet's default type, on the premise that the
default would become curvature-continuous. The default stays the circular round, so each case
now asks for the curvature fillet itself (type curvature: curvature-continuous sections and
corner patches) and keeps its grading: every seam of the rounds and of the corner patch G2, one
valid body. They are renamed from cov-fillet-g2-default-* to cov-fillet-g2-*.
The oblique three-edge corner (a block drafted 15 deg) and the pocket corner pass. Four fail, as
KNOWN_FAILING now says:
- the corner beside a cylinder: the curvature fillet builds its sections only between planar
faces;
- the four- and five-edge apex corners: refused because the default setback is shorter than
where the rounds' contact lines meet (3.90 and 3.51 mm from the apex);
- the mixed corner: SMLib sets back a corner only where its edges are all convex or all
concave.

Six fillet cases that pick their edges with no type, so they take the fillet's default, which the
owner has ruled is to be curvature-continuous (G2) at every corner, with circular rounds kept as
an option. Each grades every seam of the rounds and of the corner patch G2, on one valid body:
- an oblique convex corner (a block drafted 15 deg);
- a four-edge and a five-edge apex corner (pyramids lofted to a point);
- a pocket's concave corner;
- a mixed corner (a step: one concave edge, two convex);
- a corner beside a cylinder (the top corner of a half cylinder).
All six fail on SMLib 2fc375f, listed in KNOWN_FAILING: today's default is the circular round,
whose seams jump in curvature by 1/r. On the five-edge apex the corner patch also meets two
rounds at 8.45 degrees (G0).

Fifteen fillet cases on the test-peg's shape with clean numbers: a bar 40 x 16 x 10 whose far
end is a half disc R8, a disc R8 standing 10 on its top, joined, so the front face runs tangent
into the cylinder along x = 40 and the front top edge (convex) meets the concave arc of the top
tangentially there. Each blend ends on a face tangent to the one it rolls on.
- Rounds: both edges together at r2 and r5; one after the other in either order at r2, and at
r1.5 and r3; the front edge alone as a curvature round, whose end on the cylinder is a
semicubical cusp. The containment invariant (the unblended body's exact box, to 4e-5) and
G1 seams, or the analytic volume where the blend has a closed section.
- Chamfers: the front edge alone and the concave arc alone (analytic volumes: the section along
x up to the wall, the cone's spandrel ring clipped by the sides), both together, and one after
the other (1 then 2).
- STEP: the peg written to STEP and read back, its front edge rounded (analytic) and both edges
rounded together.
- A cone: the peg drafted 5 deg, whose front face runs tangent into a cone along a generator,
its front edge alone and both edges together.
The quadratures are tanh-sinh, converged to 1e-13; SMLib's own volumes of the passing analytic
cases agree to 4e-9. A sphere is left out: a plane meets a sphere tangentially at a point, not
along a seam, so it is not this ending.
On SMLib 2fc375f eight fail, listed in KNOWN_FAILING: every chamfer that ends tangent (status
1001, SmFilletNx1Corner), the two rounds together (the corner patch 0.0374 at r2 and 0.128 at r5
out of the front face, and the rounds meeting with normals 180 degrees apart where their
contact lines on the top cross), the same on the STEP-read peg (status 1001) and on the drafted
peg (its corner refused as unsupported).

the reported part's bar (with the sketch solver's residues) whose sides run tangent into the
cylinder, its concave arc and front top edge rounded r2 together. The plane of the front face
bounds the whole body, so every blend lies within the unblended body's exact box (SMLib's tight
box); graded to 4e-5, the corner patch's own tolerance. On SMLib 2fc375f the corner patch
stands 0.0374 out of the front face (box y min 0.0205): listed in KNOWN_FAILING.

A loop that runs out along a chain of edges and straight back (a meridian from a sphere's pole
stopping short of the other, out and back) encloses no (u, v) area, yet on a closed surface it
bounds all of it less a cut of none. The reader only read such a face when the slit already ran
pole to pole (and moved the sphere's frame onto it only then), so the 2 mm ball whose meridian
stops at 2.5 rad was refused for its empty loop.
The slit is now made the face's seams, so its loop bounds the surface's whole domain: on a
sphere, a revolution whose profile ends on its axis, or a spline closed round u that collapses
at both ends, the slit's meridian is run on to both poles, out and back (a sphere's frame put
on the slit first, whichever two points it joins); on a torus, the circle the slit lies along is
closed and the other circle through its start is the second seam. The seams on a sphere are its
own meridians (angle 0 on the equator), so their pcurves are exact lines on its form.
Tests: non_antipodal_seam_sphere_imports_as_a_whole_ball passes (its known-failing line goes);
seam_only_torus_imports_as_a_whole_ring adds a torus bounded by a slit along its tube.

A loop that uses each of its edges once each way (a whole torus within its tube and ring seams)
is the same set of uses run backwards, so it says nothing of the face's side. One written
clockwise in (u, v) turned the face over, against its same_sense: the torus came in inside out
with a warning. Such a loop is now reversed and the face keeps its side.
Test: seam_only_torus_imports_as_a_whole_ring, both orders of the two seams, volume 2π²Rr².

SMLib keeps the skirt top's offset where its loops wind the other way under the opening, the
cavity's floor (the owner's ruling of 2026-10-31: build it; a lip thinner than the wall is no

SMLib's inset now keeps only the regions that are cavity, not the one the offsets close where
they overlap (between the two faces of #545's 0.5 floor, round the up-down join's two empty
octants). The frame's core under the recess is hollowed to a sealed void, so the case says two

SMLib's merge now intersects the offsets of an edge's faces where they could not be mated along

SMLib now offsets a vertex where four faces meet (two walls and two facets at the floor's
corners, four facets at the drain) to two vertices joined by a new edge (tangency-labs/smlib
branch smlib-shells). Both volumes match their closed forms. The pocket's lining, hanging from
the top's rim round the pocket, stands apart from the slab's outer walls with the cavity rising

A blend face's name holds the edge it replaced, <face>|<face>, and a side
of that edge can be a blend face whose own name holds a |. Whether a face
is a contact of the blend was read as the edge's name starting or ending
with the face's name next to a |, so the r2 round's own face F2:side read
as a contact of the r1 round F4:blend:F1:+y|F3:blend:F1:+z|F2:side. The
edge's name is now split into its two faces, a blend side read whole as
the two faces of its own edge.

The r1 round of a block's top edge, chained onto the end curve of the r2
round of its arc at a cylinder (rig fillets/every-block-cylinder-crease-
top-edge-after-arc-round-r1), ends where it runs into the cylinder. That
edge is no seam of the r1 round: the cylinder is a face of the r2 round,
not of the r1. blend_seams takes it for one today (the r2 round's name
F3:blend:F1:+z|F2:side holds a | of its own), and the rig reads it as a

The owner's ruling: a round or chamfer that runs past an outer edge of its face into open air
builds, tangent where it has room and cut by the face beyond where it runs out. SMLib's branch
smlib-blends-past-rims builds them by the rig's analytic answers. Off the known-failing list:
the disc's rim past its 2 mm wall (190), the hole's top rim R12 past the plate's bottom, the
chamfer past the cylinder's bottom (2893), each closing on the wall continued as itself, and
926's chamfer ending on the boss's wall, which now builds to its answer too.
The sloped basins' R4 rim rounds (1080, mitred rounds built together where one overflows) build
to their analytic volumes (to 6e-9), and stay listed with that reason: their continuity check
(g1 at every blend seam) takes in the mitres' creases, G0 by the mitre ruling.
2893-chamfer-two-distances-elliptical-rim is graded as a solid (the owner: it builds) and stays
listed, waiting on the ruling on unequal chamfers along a rim whose angle varies.
5158-fillet-round-just-past-a-10mm-face stays listed with its cause found: the round passes
5e-6 under the box's top back edge, inside the body's tolerance.

A projected spline edge of several Bezier spans came into the sketch as one
curve per span (#1508), so a G2 round's bottom edge was 16 curves and a path
naming the corner named one span of it (#3604). The kernel now reads such an
edge (a spline, or an elliptical arc of several spans) as the one clamped
B-spline it is over the edge's interval, its knots and weights its own, and
the sketch takes it as one control spline whose ends sit on the edge's
vertices. Planar regions still read edges span by span. The 3604 case builds
with its original path and leaves KNOWN_FAILING.

A sketch spline over control points was always the clamped uniform B-spline
over them, so a free-form edge whose knots are not evenly spaced (or whose
weights are not 1) could only come into a sketch as one curve per Bezier
span. A control spline now may save `nurbs`: its clamped knots and its
weights. Its points, polyline, exact pieces (one a knot span; conics for a
rational quadratic), the solver's distance and curvature, links, parallel
re-projection and inspect.sketch all read them; a loaded design's are
checked. One pending format file (spline-knots).

A face tool cut with that face's surface alone, so a face of a surface body made of spans joined
tangent (a fit-point spline extruded, #3830) cut nothing where its span ends inside the body.
Split Body by a face of a surface body now takes the faces joined to it tangentially (the exact
check Extend uses, within the one angle for smooth) and slices with them as they are, through
SMLib's slice by a sheet (smlib_split_body_by_sheet, tangency-labs/smlib 7a01f1b), its sides those
of the picked face. A sheet that only nicks the body cuts nothing, as before; a lone face, or a
face of a solid, still cuts with its surface extended.
3830 comes off the booleans list. Its answer counted the two halves of the cup and not the surface
that cut it, which stays as a body of its own (4879 removes its surface for that reason): three
bodies, the volume unchanged.
Needs SMLib 7a01f1b pinned (SMLIB_REV, prebuilt; its SMLIB_ABI_VERSION 6, which crates/smlib now expects) to link.

A surface body of more than one face (a fit-point spline's spans extruded, #3830) was refused.
Each face with a picked edge is now extended alone by SMLib's extension of its surface, and the
faces are sewn back together, each the face it was. A side that lengthens onto a face meeting it
tangent takes that face along, past its edge continuing the picked one; across a crease the
neighbour grows only when its edge is picked too, otherwise the extension is refused. Faces whose
lengthened sides no longer meet are refused. Up to a target keeps the pieces every grown face
lies in.
3830's extensions now build; its split still fails (the tool point picks one span, and a face
tool cuts with that face's surface alone), so it stays on the list with that reason.

The path chain oriented its first piece, not its first curve: a first curve
of several exact pieces (a fit spline, an ellipse, a projected free-form
edge) was never turned round, so a path whose next curve meets it at its
start was refused as "not connected end to end". The chain now orients
curve by curve: the first runs toward the second where they meet at one
end only (else from the end nearest the profile), each next one starts
where the previous ended, with one joint tolerance for both questions.

The owner's rule of 2026-10-30: a round running past a rim of its faces
into open air builds; one whose section would remove material through to
a hollow behind its edge (a slit into the hollow, a cut through the part)
is refused as too large, so the fillet names the largest radius that fits.
Decided exactly in the section of a straight convex edge between planar
faces: the round's centre is at depth r below both planes, and it opens
where its arc uncovers a boundary point strictly inside the wedge with no
material beyond it toward the centre (the body's exact point
classification). Looked at: straight edges parallel to the round's (a
hollow's corner), cylinders about parallel axes (a rounded corner), and a
picked concave parallel edge's own round, which fills the corner.

SMLib's point classification at the body's own tolerance, on the exact faces and edges, in

runs on past the corner edge and is cut by the plane of the other's wall, a crease by

Owner ruling d6: the letter t of "tres long" was drafted inward by SMLib (its
loop's normal, summed from the cross products of its chords, pointed down;
fixed in SMLib). With the fix every letter grows, and the join builds at 3°
and 15° by the Round rule and by the default rule (tangent for spline
outlines), where before 15° was expected to be refused.
Exact where the outline derives it: a letter's section at height z is its
outline offset by e = z tan a, by the Round rule of area A + P e + C e² while
the offset trims nothing (Steiner; C half each loop's turning less
tan(t/2) - t/2 at each reflex corner), so the letter is
A h + P k h²/2 + C k² h³/3. Each extruded alone, the t at 3° and s, l and o
at 3° and 15° are checked to 1e-6 (SMLib measures them within 1.3e-9; its
mass properties integrate to 1e-8). The concave joins of r, n, g and e are
tighter than e already at 3° (their swallowtails trimmed: r 1.1e-3 under the
formula), the t's by 15° (9.9e-5 over), and on the block the letters grow
into each other, so the whole word is checked for what holds exactly: one
closed body with the block, and half-way up every point of each straight
letter's outline inside the solid (the t drafted inward failed that).

The blend's tangent angle is the shaded view's half degree (smooth_edges::ANGLE), one value
for smooth. A constant round lies r (sec(d/2) - 1) inside the crease it replaces (about
r d^2/8); below the edge's tolerance it changes nothing and is refused before SMLib (which
answered SM_ERR_INVALID_INPUT), naming the smallest radius that rounds,
tolerance / (sec(d/2) - 1). d is the least turn along the edge
(tangent_edge::least_angle_along, at tangent_all_along's stations).
Ruling d3 (2026-10-30). The block's tolerance is 2e-5 mm, not 0.1 um: at 1 deg the smallest

where they meet a's and b's (the patch's four corners, now asserted), so the patch takes at
most what the strips leave in that block (11.86 at 2/2/3, 32.69 at 2/3/4). The lower bound is
that block; the upper one, at most the strips' volume, stays.

A design gave another body when opened from its model cache: the rounds a body was made of
lived only in memory, so a later round at their mitre was built sequentially (or refused, as
too large) after opening and blended with them when evaluated anew. The saved model now
records, per kernel body made by rounds, the body they were made on (a place in the bodies,
stored once though no state holds it) and the edges with their radii; reading it attaches
them back down each chain, and a thinned model keeps those bodies with the bodies made from
them. Model cache format 7.

The rounds that made a body are over the body its history is over: a new history (an
operation carrying a step's result back to its own operands) leaves the record out, so a
later round never reads one history against another body. Body::rounds gives the record and
Body::with_rounds_of takes one back, checked (edges of the body before them, a fillet's
radii, the body's history over that body), for a saved model to keep it.

Two box edges rounded r2 in one fillet, then the upright edge at their mitre r3 in a second
fillet (tangent chain on, so the seam comes with it): 10 faces, 7928.743041 mm³ as

The owner's ruling of 2026-10-30: a later fillet on an edge at a vertex where earlier
rounds already meet in a mitre makes the corner rounding all of them at once makes, one
smooth patch, the mitre gone. A body made by constant-radius rounds keeps what they were
made on and which edges they rounded at which radius; a later round reaching such a corner
blends the earlier rounds' edges (from the earliest of those meeting there on) with the new
edges in one SMLib blend of the body before them. The result's history is put over the body
the later round was given: an earlier round's face is that face trimmed anew (its name
kept), the corner patch and the new rounds are the later fillet's. A picked mitre seam has
no round of its own: it is refused unless a new edge of its radius meets it.

A circle drawn as two half arcs now extrudes to one full-turn wall with its
seam edge, and each rim is one closed edge (tangency-labs/smlib#67). The tests
keep their intent on that body: a rim clicked once is one item, measured and
highlighted whole and picked from either side; a wall picked either side of
its seam is the same surface, lit whole, and toggles off from the other side;
every face is its own patch.

The Design preference surface_extrude_symmetric_per_side, which gave new
symmetric surface extrudes their distance on each side, is removed with
its Surfaces section, its session field and its labels. A symmetric
surface.extrude given no convention splits the total around the start
plane, as solid.extrude does; timeline.edit and timeline.redefine give a
one-sided extrude made symmetric the same. default_extrude_convention,
which only existed to read the preference, goes too.
An explicit `convention: legacy_per_side` and the marker saved designs
carry are unchanged. A saved preferences file that carries the key loads

a custom metric size the table lacks still takes the major less the pitch.

SavedModel::thinned wrote `"validation": null` into the records of a model

a_model_cache_too_big_for_the_file_keeps_fewer_states). It copies the mode

An imported solid's faces were mapped to the file's only when SMLib's export numbered them as the
record did (native.rs, numbering). The export is in canonical order, which can list edges
otherwise: the two periodic-knot tubes of #1374 came back with their seam and rim edges listed
[2, 0, 1, 5, 3, 4], so the sheet, a valid B-rep, was refused as "SMLib renumbered the solid's
faces". The export's order says where SMLib's own face and edge i went; put back in SMLib's
order it numbers them as the record does, and SMLib's i is the record's i (an import lists them in
the record's order). numbering now takes that too, checked the same way; an edge split into
pieces is no renumbering and stays unmapped.
The tube test asserts what it should: one surface body, not a mesh, its faces the file's two
faces in order, every face meshed, in under a minute, and the area exact: each face is the file's
quadratic circle (corner weights sqrt(2)/2 to 12 digits) moved straight along its axis, a
cylinder's side, so 2 * 2 pi r h, which SMLib's measure meets to 1e-6.

A solid SMLib refused came in as a surface body of its faces; where SMLib could not stitch those
either, the importer meshed them with SolidCraft's planner and kept the triangles as a mesh body
(step_in/parallel.rs, mesh_part). A build without SMLib showed it: every STEP part of the import
rig came in as a mesh of its faces. That fallback is gone: the solid is not imported, and its
warning names it and gives the kernel's reason ("solid 'Cube': not imported: ..."); a file whose
every solid is refused fails with the same words.
The import report tells a part the kernel refuses (Refused) from one the reader cannot read
(NotImported), and its summary says "N parts couldn't be made into solids and were not
imported" in place of the mesh sentence (en, ar, de, he, ja, ko, zh). STL, 3MF, OBJ and glTF
still come in as mesh bodies: that is what those files are.
The two-tube sheet of #1374 had come in only through that fallback: SMLib's export lists its
edges in another order, which the next commit maps. Until then its test asserts the refusal and
meshes the faces as read at the body's coarse display tolerance, the regression it guards.

Since the body check mode became part of the evaluation context (9acbcf924),
evaluate digests the context with the mode, but Model::adopt still took the
context without it and the default mode: the first evaluation after opening a
design from its saved model saw another context and recomputed every feature
(undoing_an_edit_after_opening_reuses_the_saved_results,
rolling_the_marker_back_keeps_results_after_cache_eviction). The saved model
now records the mode it was evaluated under (thinned ones too), adopt takes
it and digests the context as evaluate does, and a session opening a design
under another mode evaluates it again rather than showing that mode's results.

Tests that asserted an older design rebuilds as the build that saved it made it
now assert what still holds: it opens, is upgraded, evaluates, round trips and
names alike every time, and a feature that lost a reference asks for it again.
- naming corpus: two builds still name every face and edge alike and find the
same faces with their stored names; a stored name that finds nothing must
leave its feature failed (it asks to reselect), never a feature that builds.
A sketch's face is found by its name as the sketch finds it.
- design corpus: the volumes, areas and bounds the saving builds recorded are
no longer compared; a corpus design may fail only by a request to reselect,
and undo leaves the features that failed on opening failed.
- fixed robustness seeds: no panic, valid bodies and volumes moving the right
way; a step the kernel refuses is not a bug.
- a format 28 design's pieces and a format 13 design's extra bodies: marked as
they open and named alike, without promising the numbers or names saved.
- action matrix baseline: the two corpus designs whose fillets, chamfer and
offset face held names saved before format 14 re-recorded.

Face and edge names stored before format 14 were worked out from geometry and
open marked `?`. They were found among the names geometry gives today, as the
builds that saved them found them, pieces by the one nearest the pick. They
find nothing now: the feature holding one fails, asking for its reference to be
picked again, which stores its exact name. The legacy face and edge names a
body worked out for them are gone.
The tests that found such names as saved now assert the request to reselect:
a saved strip projection, a version 9 emboss on an annulus, a format 10 face
sketch and the corpus design named with numbered pieces.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A face or edge name a feature stored finds only the face or edge it names: the
very name (or a synonym of that face), or the named piece told apart by the
faces around it. A face split into several pieces, merged into another face,
or left only as a face of the same stem is not the face that was picked, and a
name found on several bodies is told apart only by the body the reference's
point lies on. The fallbacks are gone: no piece nearest the pick, no merged
face, no edge at the picked point, no lost link that keeps its last geometry.
A feature whose stored reference finds nothing fails with DocError::Reselect:
blends, face points, sketch planes, sketch projection links, construction
references, hole reference edges, sheet bend edges and cylinder emboss.
The tests that asserted a fallback now assert the request to reselect: split
and removed fillet edges, a merged or rejoined face, a projected edge that was
split or is gone, a projection whose body went, saved strip projections after
wall coalescence, a fillet saved on a piece of a tapered side that is whole
now, a cut that starts from a piece that is no longer that piece, and a fillet
named on the lower of two stacked boxes.

A side drawn in collinear sketch pieces is one face the extrude made from each
piece (#1788): its first role is its name, and the others were kept as aliases,
like the names of faces merged into it by a later join. They are names of that
very face, not of faces merged into it: the face keeps them as synonyms, which
a stored name matches as exactly as the face's name (a piece of it, once it is
split), through copies and later features, and the face whose name a merge
keeps keeps its synonyms too. An extrude-side certificate made on one of the
pieces finds the joined face the same way, and the saved model records the
synonyms (model cache format 5).

Each component's bodies lie in its own coordinates in the state a feature's
points are named in, so a part inserted twice has a face at the same point in
each copy: a thread on the second copy was named after the first copy's face.
The points are named on the feature's own component's bodies first, then on
every body for a point that lies on none of them.

The model carries the mode (Model::set_validation) and runs each feature
under it. When a step left its check, every body the feature made or
changed is checked by SMLib before the state is kept: a body the check
refuses fails the feature with the check's reason and the body's name.
The mode is part of the cache context, except each_step, whose results
are develop's.
Validation::EachStep checks every solid sweep, boolean and blend result
in SMLib as before; EachFeature leaves those checks to the end of the
feature and says a check was left; Off skips them. The evaluation installs
the mode around a feature (validating), as watch installs a watch; outside
it every step is checked as always, and the kernel's worker threads run
under the caller's mode.
Under EachFeature a body decoded from a step keeps that step's SMLib
result (for its own record only), and check_kept checks it as the step's
own check would have, then lets it go; any other kept body is checked as
SMLib imports its record. The record can pass where the result fails: a
fillet's surface of revolution whose polar curve SMLib's check refuses
(fillets/1080-fillet-sloped-basin-1-mm-rim-r0-5-4-edges) is rebuilt on
import, and its round meets a wall at 72 degrees; checking the record
alone kept that round.
The largest-size search of a blend checks every candidate as it is built,
whatever the mode: a candidate fits only as a body the check accepts.
Surface operations and stitching keep their checks.

The owner's ruling of 2026-10-30 (d7): a chamfer that reaches or runs
past a rim builds, everywhere, as SMLib's cliff overflow builds a convex
blend: on its faces' continuations, then cut by what the cliff cuts
away. The earlier rule refused a chamfer whose leg runs off its face.
SolidCraft has no such refusal of its own; SMLib refuses these, so the
cases fail on SMLib 985faaee and are listed with its reasons (traced in
gdb at SmFilletErrorInfo::NoteError):
- the sloped basin's single front edge past its rim (1 mm rim 2 and 3,
0.5 mm rim 4): CloseRemovalRegion, "a cliff overflow's fillet boundary
lies on the surfaces of two faces": the sheet's boundary along the end
wall's top edge line from the edge's vertex to the top's contact
(x = 20, y from -1 to 1, z = 30) lies on the top's plane and the end
wall's both.
- the equal-slope basin's rim loop 2 and the 5 mm pocket's rim 5.5:
CloseRemovalRegion, "a cliff overflow's fillet boundary closes on one
face" (every edge of the loop blended).
- the sloped basin's front and right edges 2: status 1001,
SmFilletNx2Corner, CalcFilletIntSideFace.
- the cylinder's rim 2 across the top and 25 down its 20 mm wall: status
1001, SmFilletNx1ClosedCorner cannot compute its geometry.
Expectations, each from a closed form or an exact quadrature:
- chamfer_wider_than_sloped_basin_rim_is_refused becomes
chamfer_wider_than_sloped_basin_rim_builds, ignored until SMLib builds
it: the triangle clipped to y >= 0, times 30 + z (shoelace):
73.450475, 142.112912, 184.526613; the rig's 1080-chamfer-sloped-
basin-*-past-the-rim cases: V = 144459.882858, 144391.220421,
144082.140054.
- blend_corner's a_rim_loop_chamfer_running_off_its_rim_is_refused
becomes ..._builds, ignored likewise: sliced at depth t the mitred loop
takes the pocket's rectangle grown by w(t) = d (1 - t / delta) on each
side, clipped to y >= 0, less the rectangle, Simpson exact on each
quadratic piece: 375.673069, V = 139957.660264 (the rig's
1080-chamfer-equal-slope-basin-1-mm-rim-loop-2 too).
- 5835-chamfer-sloped-basin-1-mm-rim-2-two-edges: the same slicing with
the front and right sides grown, 161.279149, V = 144372.054184.
- every-chamfer-pocket-rim-5-5-past-the-floor: 50 d^2 + (4/3) d^3 at
5.5, the groove 0.5 deep round the floor included, V = 19265.666667,
15 faces.
- 2893-chamfer-two-distances-past-the-bottom: the frustum r 8 to 9.6
over 20, pi 20 (64 + 76.8 + 92.16) / 3 = 4879.102831, 3 faces.
Each drops "-refused" from its id (the 5.5 pocket's says past the floor).
The same slicing reproduces the existing 5835-...-4-mm-rim-2-2-edges
(176.006388), equal-slope loop 0.5 (24.455545) and half-width
(5.426545) values.

The owner's ruling of 2026-10-30 (d7): a chamfer that reaches or runs
past a rim builds, everywhere. The earlier rule refused a full-width
chamfer, naming the largest size that fits. SolidCraft has no such
refusal of its own (a blend's TooLarge is SMLib's SMLIB_ERR_NO_ROOM,
and the doc layer only names the largest fit), and SMLib already builds
these, so only the expectations change, each from a closed form or an
exact quadrature:
- chamfer_wider_than_sloped_basin_rim_is_refused's full widths become
chamfer_as_wide_as_sloped_basin_rim_builds: the whole triangle,
d drop / 2 (60 - drop / 3), drop = 20 d / sqrt((20 - margin)^2 + 400)
(shoelace over the section, its length 30 + z between the sloped end
walls): 21.662379 (1 on 1 mm), 5.359321 (0.5 on 0.5 mm). The basin and
the removal move into sloped_basin and sloped_basin_rim_chamfer_removed.
- fillets/1080-chamfer-sloped-basin-{1,0-5}-mm-rim-as-wide-as-the-rim:
V = 144511.670954, 144261.307346.
- fillets/every-chamfer-pocket-rim-5-full-depth: 50 d^2 + (4/3) d^3 at
d = 5, V = 19583.333333, 11 faces (the walls used up).
- fillets/every-hole-top-rim-chamfer-10-full-depth: the triangle 10^2/2
revolved at rho = 5 + 10/3 (Pappus), V = 16000 - 3250 pi / 3 =
12596.607959, 7 faces.
- fillets/1113-chamfer-arc-top-edge-full-wall-height: the 9.5 case's
Int rho asin(21/rho) h(rho) drho at s = 10, by Gauss-Legendre in
u = asin(21/rho), 1303.400331, V = 8287.993768.

A joint drive with contact on tested each sample and each of 14 bisection
steps with a brute-force mesh-against-mesh overlap check, its cost the product
of the two display meshes' triangle counts under a fixed budget. Since the
display mesh puts nodes inside planar faces, a cam and its tappet or a block and
a sphere exceed that budget ("motion exceeds contact sweep collision budget"),
and whether a motion may run depended on display tessellation.
Now, at each sample, bodies whose exact boxes meet are intersected exactly
(SMLib boolean, exact volume); a shared volume is a contact, a touch (a cam and
its follower) is none. Between the last clear sample and the first overlapping
one the drive closes in by conservative advancement: from a clear placement it
moves no point of the pair further than the pair's exact gap (body_distance),
until the gap is within 1e-9 of the bodies' size. Only clear placements are
measured, so no intersection is asked to tell touching from overlapping within
its tolerance (SMLib's boolean fails there, status 1001, on two cubes 1e-4
into each other). The budget is 2048 intersections per drive.
Fixes cmd::joints::tests::cam::a_cam_drives_a_closed_loop_and_stops_at_a_contact
and contact_sweep ordinary_curved_bodies_stop_at_their_contact_within_the_sampling_budget,
and the other contact, cam, motion, interference and clearance tests pass.

A G2 corner patch's side is G2 to its round except near the face it ends
on, and SMLib holds each side as two edges. The smooth-join test judged
each edge alone, so the G2 half was hidden and the line stopped at the
vertex in the middle of the seam. Edges between the same faces that
continue each other at a shared vertex now share one verdict: smooth only
where every one of them is.

The block solve kept its sparse entries in hashed maps and summed the coupling of each patch's
interior onto the shared unknowns in the map's order, which a hashed map draws afresh each
time: the same loop filled to surfaces differing in their last bits, so a design read back
rebuilt another cap (engine patch_continuity_and_points_cap_a_tube, "the same surface read
back"). The entries are now in ordered maps; a fill twice of the tube's ring and of a hexagon
about a centre are bit for bit the same.

A tube's end has no corner at all; the kernel gives its circle in four quarters, and one patch
on them has a corner on each quarter joint where the loop runs straight on: flat, its two
derivatives parallel, which SMLib's check refuses (Bad Surf FlatCorner within 0.5°). Any
layout with a patch corner on such a loop has one.
Such a loop is now the ring of structured meshing (an O-grid): four patches each on one side of
the loop, two meeting at every point of it, about one inner patch (Quilt::ring). The spokes are
now any curve two patches share (Seam), each glued G1 with linear gluing functions: at an inner
vertex of valence m the characteristic value ±2cos(2π/m) (the centre's spokes as before, the
ring's inner corners with m = 3), at the loop what its two sides' derivatives there ask
(foot_gluing; 0 and their speeds' ratio where the loop runs straight on). IsoFill says where each
spoke starts and ends (SpokeEnd) and holds the inner vertices; the kernel builds them so.
The tube end caps G1 (normal within 0.0157° of the wall, sealed 10458.232 against the tube and
dome's 10458.232) and G2 (curvature across 4.6e-5 /mm against G1's 0.30), five faces with no flat
corner. A crown on the ring lifts the inner patch whole (the ring rises as v(2 − v)).
Saved designs: a general patch on a smooth closed loop (a tube's end) rebuilds as five faces
where it was one (which SMLib refused).

The crown moved the free points along the patch's own normal, whose sign is only the way the
patch happens to be parameterised: the pentagonal window's crown 0.1 sank 1.56 mm into the
cylinder (the middle 9.959 from the axis plain, 8.395 crowned) where the kernel documents it
filling out to the side the G1/G2 neighbours' normals face. The crown now takes that side: the
sum of the patch's normals against the neighbours' over the stations sets one sign for the fill.
The pentagon's middle goes out to 11.526.

The crown's bump went onto the first net with any control point clear of the loop; a coarse
net could leave points supporting the box's middle without it, so the middle rose by only a
share of crown · size (the pentagonal cup: 7.6558 of 13.3877). The net is now refined (knot
insertion, the surface unchanged) until every point whose basis is not zero at the middle takes
the bump, where the middle is inside the loop: the bubble is then exactly 1 there, as fill_loop
documents.
The kernel test measured against the face's domain, which SMLib holds as the loop's extent; the
documented box is the height field's whole domain, the loop's box and 1% more each way (as the
engine's crown test says, 28 × 28 + 1%). Its diagonal is 1.02 times the face's, so the
documented rise is 0.25 × 53.5506 = 13.387661 = 1.02 × 13.125158, which the patch now meets to
1e-6 for crowns ±0.25.

A face's domain and pcurves are on Face::parameters() (its NURBS form when it has one, the
record's documented contract); the general fill tests' quadrature and the pick-order and crown
comparisons evaluated Face::surface instead. A fill SMLib recognises as an analytic surface (the
240° window's G0 patch is the cylinder itself) then read its arc-length domain as angles: the
quadrature came out 4188.79 for the window's 418.879 (10 × 41.888 of angle against 4.189).

A vertex where the loop runs straight on (SMLib's seams: a cylinder's at 35.12° splits a half
circle into two arcs) was a corner of the fill's region, so a patch had a 180° corner there:
flat (its two derivatives parallel), degenerate, and refused by SMLib's check (Bad Surf
FlatCorner, within 0.5°). Half a post's side, six edges on four corners, was six patches about
a centre and folded.
The region's corners are now the vertices where the loop turns by more than the kernel's corner
test (1°, IsoSpec::corner_turn); a side is the chain of edges between two corners, held as one
exact B-spline (each edge carried exactly to the side's degree on its stretch, joined at a knot
of full multiplicity, which the knot-line rows keep tangent across). Each edge's pcurve is still
a straight line, now on its stretch of a patch's side; a spoke says where on the loop it starts
(IsoFill::feet). A loop with fewer than three corners keeps its edges as sides.
The half post is one face again (a_loop_that_does_not_bound_a_height_field_fills_with_one_face),
the 240° window is one patch, the exact cylinder (area 418.879), and the torus window fills G0
and G1.
Saved designs: a general patch on a loop with seam vertices rebuilds with fewer faces (the half
post's 6 become 1), its corners where the loop's are.

Across each spoke the two patches' derivatives away from it were held opposed (parametric C1).
At the centre that asks the spokes' tangents d_{k-1} + d_{k+1} = 0, which for N other than a
multiple of four only d = 0 meets: every patch got a flat, singular corner at the centre (a
pentagon on a wavy rim: derivatives of 3.3e-5 there; the hexagonal rim's control net doubled
back and SMLib's check refused it as NonMonotonic).
The join is now G1 with the linear gluing function of Loop, Peters and Hahn:
d/du S_k + d/dv S_{k+1} = alpha(t) d/dt S along the spoke, alpha(t) = 2 cos(2 pi / N) t. At the
midpoint alpha is 0 (the edge's two halves leave it at the same speed, opposed); at the centre
it is the value any affine image of the regular N-star meets, d_{k-1} + d_{k+1} = 2 cos(2 pi/N)
d_k. N = 4 is the old row. The pentagon's centre corners now open 72° with derivatives of 16.2
(N = 5 to 8: 360°/N each).

A tensor patch's cross derivative along a side is, at a corner, the tangent of the side it
meets there (the two share the corner's next control point): the compatibility condition of
Coons and Gregory interpolation. The weak rows asked t·c′ = 0 and w·c′ = s right up to every
corner, which no patch can meet where the next side is not square to the edge; at a smooth
vertex (a tube's end in four quarter arcs) the next side runs along the edge itself. The least
squares spread the contradiction into the first spans and folded them: the tube end's worst
normal went 13.8°, 17.9°, 89.8° (folded), 85.6°, ... 25.1° (folded) with refinement, and the
symmetric loop came back asymmetric.
The target is now the Coons start's own cross derivative, compatible at every corner by
construction, turned about the edge into the neighbour's tangent plane (its part along the
edge kept, the rest laid along the leave direction at its length). The tube end converges
21°, 3.8°, 0.76°, 0.18°, 0.045°, symmetric, and does not fold.

An edge SMLib reports as new was given the origin "where its two faces meet", each side what
that face came from. A split line lies between two pieces of one face, so both sides are that
face and the edge read EdgeOrigin::Meet { top, top }: a face meeting itself, which no two faces
did. Such an edge now has no origin, as the history's EdgeProv documents for a new edge between
faces new to the operation (the doc now names the split line too).
New test: a_split_line_comes_from_nothing (one face split in two, its new edge has no origin).
modify_history_tests::split_a_face checks this at its last line; it still fails earlier, on its
counts ([3, 2, 2, 0, 0] for [5, 0, 2, 0, 0]) on develop's SMLib pin, until SMLib batch 3's
history fix (03bbc88) is pinned.

The closed-box certificate took exactly twelve triangles, two a face. The one mesher puts
interior points on planar faces (a 20 x 20 x 2 box comes in more than twelve), so
render.preflight refused a box as "unsupported dielectric boundary tessellation"; a box is a
box however its faces are triangulated.
The certificate now reads the mesh's geometry exactly: every triangle in the plane of one of
the faces of the box its points span (corners on it, normal exactly that axis) facing out,
and the triangles a closed, consistently oriented surface (each edge, by its ends' exact
coordinates, run once each way). Such a surface is a 2-cycle on the box's boundary, a sphere,
so it covers every point of it the same k >= 1 times, and its area is k times the boundary's:
k = 1 is decided by the area being under 1.5 times the boundary's. Up to 65536 triangles. A
thin sheet is still one or two triangles; a general closed mesh is still refused.
New test: a box with its top fanned from a point in it is certified, with the same bounds;
the point 1e-9 off the plane, or the top covered twice, is refused.

A tapered extrusion of a region with holes checks, at its two ends, that each hole's section
stays inside the outer loop's and clear of the others. Those sections were made with the
start section's rule, which refuses a line the offset swallows ("draft extrusion that starts
before its profile where the taper closes a side"). At the far end such a line is ordinary: a
short line between two concave corners whose wall closes on the way up. The letter g of
"tres long" (8 mm, joined 2 mm with a 3 degree taper) has one, and the whole text was refused
with a message about the start that does not apply.
The end check now takes the section as it is there (offset_loop's swallowed lines left out, their
neighbours meeting where they were); whether the closing wall is built stays the draft's to
say. The g builds at 3 and 15 degrees.

raked_wedge (#1617, test from 7f2ae11a0 on 2026-10-17) rounds four end edges R4. Since
84bd2daad (2026-10-22) solid.fillet carries each picked edge round its tangent chain by
default, so the R4 now ran on round the end outline onto the R1.2 round's end arc, where the
round's rail on the end face would be an arc of radius 1.2 - 4 < 0, and it is refused as too
large. The issue's R4 rounds those four edges alone: the step says tangent_chain: false.
The test still fails, one step later, on SMLib: the issue's R0.854 round of both ends' outline
is refused by SMLib's own check (SmBSplineSurface Test #5, "close to singular at boundary"),
reported for the SMLib batch.

tiny_cut_inside_exact_circle_survives_unfold_refold_and_dxf cut a 50 nm square 0.2 um inside
the disc's rim. SMLib models at a zone tolerance of 1e-4 mm: its check refuses the cut's 50 nm
walls as planes "degenerated to a point (tolerance=0.0001)", so the extrude was refused. A
feature below the kernel's resolution is not one it can keep, on any path.
The test's point is that the exact circle, not its display polyline, bounds the flat pattern:
a cut between the two must survive unfold, refold and the DXF. The polyline at 1e-3 has 224
chords (sagitta 10 (1 - cos(pi/224)) = 0.98 um), so the square is now 0.2 um across, centred
0.4 um inside the circle on the first chord's bisector: outside the polyline, inside the
circle, its walls and its 0.3 um gap to the rim above 0.1 um. Its hole's area is
(2e-4)^2 = 4e-8 (was 2.5e-9 for the 50 nm square).

A strip's far curve, where its rulings turn along the edge, is a B-spline in the edge's own
spline space. A straight edge's space is one linear span, which holds only the chord between the
strip's corners: the rulings' ends (the closeness term) had no say, and the strip had no handles.
Off the patch over the cup's rim in a_strip_off_a_curved_face_is_ruled_to_its_far_curve the
normal along the straight rim at x = 14 turns by 5 degrees (x component -0.350 at the ends,
-0.262 at the middle; the patch's middle is at z 10.296, not the cylinder's 10), so the strip is
free and its rulings' ends lie up to 0.26 mm off that chord.
Such an edge is now taken as the cubic Bezier it also is (exact degree elevation: control points
at thirds, the same points at the same parameters) before the far curve is solved, so the far
curve has two interior control points: its handles. Exact strips on straight edges keep the line.

Since 6cc759750 an extruded circle is a cylinder over the face's trimmed range, and the circle was
fitted through three points of that range. On the shallow strip of the extruded-ellipse test
(radius 3000, 6 mm wide: 0.002 rad round) the three points are 2 mm apart and the fit is
ill-conditioned: the centre came 2.5e-10 mm off the circle's plane (the frame's x axis tilted
8.3e-14 out of it) and the radius 8.1e-9 mm short. SMLib took that cylinder, but on the way back
(the import's SMLib round trip, then Body::smlib) SmCylinder::IsNurbSurfaceCylinder did not find
a cylinder in SMLib's own NURBS of it, and the strip was refused as needing repair
(SM_ERR_INVALID_INPUT, AnalyticOfNurbs). Before 6cc759750 the fit ran over the record's domain,
1.4e-6 rad wider on each side, and happened to come out level.
The patch's trims were right all along: they straddle the profile's seam (u = 4, the knot
between the spline's two quarter spans) without wrapping, [3.9992930395761980, 4.0007069604238020],
which is the exact 0.001 rad either side of it.
The circle is now fixed by three points on the arc's widest knot span (a quarter turn here),
where it is determined to rounding, and checked as before at 65 points over the face's range.
A revolution's profile circle is fitted as before.
Regression test (smlib import tests): a 0.002 rad patch of an extruded circle of radius 3000
across that knot is the cylinder of radius 3000 to 1e-10 (it was 2.8e-10 short), its axis
along z to 1e-15, over exactly the patch's range.

a_long_setback_keeps_the_g2_patch_inside_the_box measured the patch's reach past the box on
the vertices of a display mesh at chord 1e-3, so where the tessellation's nodes fell decided
the result (#9307 moved them). It now brackets the highest max(x - 60, y - 40, z - 20) on the
patch within its trim from the exact B-spline: the surface cut into its Bezier patches, split
by de Casteljau while a patch's control hull can still beat the best surface point found
inside the trim (the pcurves), so the hull bounds it from above and the patch corners from
below.
Body::exact_bounds (SMLib's SmFace::CalculateTightBoundingBox) is not used: it gives the
patch 40 + 1.4e-14 in y at set back 12, while the surface at (u, v) (-1.509, 8.041), inside
the trim, is at y = 40.00133 (a mesh node there agrees).
The bound is 1e-9 mm: the body is convex, a convex face lies inside each tangent plane, and
the patch meets each box plane tangentially along its seam, so it reaches past none of them
but by rounding. The exact extent shows the patch does reach past the box at every setback,
each time 0.4 to 0.65 mm from a hole corner (where a round's section ends on a plane, inside
the fill's fade zone): 7.0776e-4 (s 11, z), 1.3298e-3 (s 12, y), 2.6338e-6 (s 13, y),
5.1293e-5 (s 14, x), 4.7891e-4 (s 15, x). The test fails with these numbers until the patch
construction keeps the fill convex there.

Zebra, Draft, Curvature Map, Environment Map, Accessibility, Continuity,
Isocurve and Curvature Comb are one group: turning one on turns the one on
before off (Session::analyses_off), and the session says which is on

turns it off (typed contract and reply). The toolbar shows the active one's
button pressed, its tool running or not. Curvature Comb's button toggles:
on, the tool combs the edges clicked; again, off and the combs go; Esc or a
right click in the tool turns it off; opening another dialog leaves it on.

inspect.curvature_comb keeps what it shows in the session (Session::comb):

shares one scale and tooth lengths compare across curves (a curvature jump
where two edges meet shows); with nothing picked it draws those shown again
with new options; clear: true ends it. Each sketch curve keeps its own
sketch. The tool runs it once per pick and per Comb length / Teeth change,

This replaces the spline fallback of 64efbe7f6. A face SMLib holds as a rational spline that is
an extruded circle was recognised as a cylinder over the spline's whole parameter range: for the
upper half of the peg's wall after the front top round that range runs 393 degrees round (u in
[-15, 40.18], SMLib's support surface extended past the face), and SMLib refuses a cylinder past
one turn. The face itself, its loops' box, spans u in [0, 8 pi]: half a turn. The cylinder now
takes the face's trimmed range, the least and greatest u and v of its uses' pcurves over their
edges' intervals, found to rounding on each Bezier span (the values at the pieces' ends bound the
extreme from below, the control points from above; pieces that cannot beat the best are dropped,
the others halved). A face whose trims run more than one turn round is no face of a cylinder: it
is refused as an invalid record, never kept as a spline.
The peg (40 x 16 x 10 bar, R8 end, a disc R8 extruded 10 up on its top, joined), front top edge
rounded r2: the body measures to 1e-7 of its closed form, the three r2 corner rounds after it
build and measure, and the upper wall comes back from SMLib a cylinder of radius 8 (engine test).
The rig case of the round of the edge where that round meets the wall (tangent at one end) still
fails, for another reason: on the wall as its exact cylinder SMLib refuses the round as larger
than the faces beside its edges allow (it fades to nothing at the tangent end) instead of
returning a body its own check refuses. Its KNOWN_FAILING line says so.

This replaces the five fixed stations of 0a166bf3d, which compared the faces' normals at the
edge's ends and quarters: a sampled guess that misses a crease or a tangency between stations.
Along each use's pcurve (on the edge's own parameter), the face's natural normal Su x Sv is a
polynomial in t on every piece where the pcurve stays in one span of its knots and one knot cell
of its surface: of degree (2p + 2q - 2) r for a B-spline surface of degree (p, q) and a pcurve
of degree r, (4p + 4q - 2) r for a rational one (its homogeneous form), 0 for a plane. The cross
product of the two outward normals is then a polynomial of degree D, the sum, and it vanishes
on the piece iff it vanishes at D + 1 points of it (the piece's Chebyshev points). Pieces end at
the pcurves' knots and where a pcurve crosses a knot line of its surface (periodic copies too),
each a root of U(t) - k W(t) on a Bézier span, isolated on its Bernstein coefficients. A point
where the normals differ is a witness of a crease; agreement at all of them is a proof of
tangency (crate::tangent_edge). Outward normals opposite (a cusp, a knife edge) is not smooth,
as SMLib's GetBlendEdgeuse has it since fork 81f411d; a seam, whose two uses are on one face,
is smooth.
The C API has no edge classification query; SMLib's own (GetBlendEdgeuse at t = 0.34,
IsTangentSector at five stations) is sampled too. A fork item to make it exact and expose it is
written up for the SMLib batch. The tangent-chain walk decides each edge once.
The bar whose front face runs tangent into a cylinder R8, its front top edge rounded r2: the
round's contact with the front face and the front face's tangent line with the wall are smooth;
the round's edge with the wall (tangent at (40, 0, 8) only) and a box edge are creases; the
knife edge of #851 is a cusp, not smooth (blend.rs test). The blend, fillet and chamfer kernel
tests and the fillets rig keep their outcomes.

A curvature-continuous fillet (type curvature, equivalent radius 2) of the three edges at a top
corner of the owner's bar built, but its corner was SMLib's own patch, which is only tangent to
the rounds: Continuity Analysis measures a 35.8 / mm curvature jump across its seams (with the
rounds G2 to the faces everywhere else), and it shows as a dome sitting on the corner, the
vertical round's shading lost under it. All three edges were rounded; the corner was not
curvature-continuous, and nothing said so.
Such a corner, where three or more rounded edges meet, is now set back (1.5 r unless a setback
names it) and left open by SMLib with the curvature sections (smlib_blend_setback_open with
SMLIB_BLEND_CURVATURE), and filled with the G2 patch fillet_g2_corners already uses for circular
rounds (fillet_g2_with_g2_corners). The `corner` option no longer leaves a curvature fillet with
SMLib's patch: its corners are always G2, and setbacks on it set back the curvature rounds (they
were circular rounds before). Where SMLib or the patch cannot build it, it is refused.
On the reported geometry every seam of the rounds and the patch is G2 (rig
report-fillet-curvature-three-edges-at-bar-corner-solver-residues), and the rounds outside the
setback cube measure exactly: V0 - 27 - (the quintic section, A2 = 0.597884, along the front edge
from 3 to the wall and along 7 and 13) = 9541.116961 (...-outside-setback). With round coordinates
SMLib's open sheet fails its own check (a 2D curve cusp, SmBSplineCurve test 13): the fillet is
refused, listed as known failing (report-fillet-curvature-three-edges-at-bar-corner).
Test: corner_g2_tests::curvature_rounds_meet_at_a_g2_corner (box corner, r5: the patch's jump
under CURVATURE_SHARE / r clear of the hole's corners, SMLib's own patch over ten times that).
Changes a default: a saved curvature fillet with such a corner rebuilds with the G2 patch; there
is no preference or fallback to SMLib's patch.

The cases from the owner's reports in the app (no issue) were named and cited after issues they
only resemble (#9, #896, #1207). They are report-<name> now and list no sources; their `what`
says where they were reported. The README gives the convention (report- for a report with no
issue or pull request, cov- for a command with no source).
report-fillet-g2-corner-of-bar-running-into-cylinder was graded by a 3^3 volume band and a face
count, which say little about a G2 corner. It keeps the band (provable: the patch differs from the
rolling ball only within the setback cube) and adds the corner seams' curvature jump, as
fillets/9-fillet-corner-r1-curvature-default-setback scaled by r = 2 (at most 0.0025 / mm, clear
of the hole's corners by 0.48 mm, within 4.4 mm of the corner). A new
...-outside-setback case cuts the setback cube [-1, 3] x [-1, 3] x [7, 11] away and grades the
three rounds outside it exactly: V0 - 27 - (front spandrel from x = 3 to the wall + (1 - pi/4) r^2
over 7 and 13) = 9342.029541. The bare face counts are dropped.
The -solver-residues recipes now take the reported sketch's points exactly (the arc's end

A 220 x 11 two-distance chamfer of a tapered plate's bottom front edge (rig fillets/5181) runs up
the front face past its straight side edges, l2|start and l6|start, and takes them up: no result
edge comes from them. SMLib leaves the blend face untagged, and it was given every blended edge
whose two faces lie next to it: the picked edge l1|start and both taken-up side edges. Its name
came from the first in edge order, F3:blend:F2:side:l6|F2:start, an edge the user never picked.
A blend face now comes from the picked edges it lies between; only a face that lies between no
picked edge's faces (a corner's piece over a short edge the corner took up) comes from the
taken-up edges it lies between. The chamfer is F3:blend:F2:side:l1|F2:start everywhere on it.
Persistent names: a blend face that also lay between the faces of an edge the blend ran over is
now named by its picked edge only. There is no alias for the old name (5181's
F3:blend:F2:side:l6|F2:start): a saved reference to it is reported lost.
Also corrects 5181's "what": the chamfer builds (335399.749), it is not refused.

The edge where a round runs into a cylinder's wall it is tangent to at one end (the bar's front
top round meeting the wall at (40, 0, 8), where the round's contact with the front face meets the
wall's tangent line with it) was refused as smooth, "nothing to round": the faces' normals were
compared at the edge's start alone, which was that tangent end. They are now compared at five
stations from end to end, and an edge is smooth only where its faces meet tangentially at every
one: this edge is a crease everywhere but its end. The wall's seam with the front face, tangent
all along, is still refused as smooth.
The round of that edge with its tangent chain (the top's concave arc) now reaches SMLib, whose
result fails its own check (internal poles, coincident control points, cusps where the round
fades out): its rig case in fillets is listed as known failing for that SMLib defect.

A round of a bar's top edge, where the bar's side runs tangent into a cylinder standing on its
round end, seemed to build: SMLib's result holds the cylinder's wall as a rational spline whose
parameter range runs 393° round (u in [-15, 40.18]). Going back into SMLib (to measure the body
or change it again) the record's extruded circles become SMLib cylinders with the face's range on
them, and that range was 6.866 rad: SMLib refuses a cylinder past one turn
(SM_ERR_INVALID_INPUT from BrepFromFlat's face range check). The body could not be measured, a
second round on it failed, and the app said one of its freeform faces can't be used. An extruded
circle whose range runs more than one turn round now stays the exact spline it is.
The bar of the reported design (40 x 16 x 10 with a R8 end, a disc R8 sketched on its top and
extruded 10 up, joined): the front top round removes the spandrel up to the cylinder's wall,
integral over y in [0, 2] of (2 - sqrt(4 - (2 - y)^2)) (40 - sqrt(64 - (8 - y)^2)) = 32.306475;
the three rounds at the other top corner after it remove 53.285832 in all (spandrels outside the
corner cube, the cube less the rolling ball's eighth). Both now build and measure to 1e-7; the
curvature corner of the three edges at once (setback 3) builds too.
Rig cases (fillets) for the three reports: the curvature corner of the three edges, the front
top round, and the three corner rounds after it pass; the same corner rounds with the design's
~1e-10 mm sketch residues fail in SMLib (its corner's surface of revolution is close to singular
at its boundary) and are listed as known failing. (Their ids take the report- convention in the
rig commit later on this branch.)

The owner ruled on 2026-10-30 that rounds meeting at a concave corner beside an
unpicked sharp edge are mitred, which fixes the basin loops' re-entrant corners.
Each loop case now grades its exact volume (rel 1e-6): each blend takes
Int width(z) length(z) dz, its section's width from its wall to its arc or chamfer
line (the front one clipped at the slab's face where it runs past the rim), its
length between its neighbours' walls extended; each corner of two picked edges adds
the overlap of their section prisms in the quadrant beyond both walls,
Int width_1(z) width_2(z) dz (r^3 (5/3 - pi/2) for vertical walls, as
every-pocket-rim-edges-r2). One edge alone reproduces the single-edge closed forms to
3e-7 of the removal. The equal-slope chamfer loop 0.5 passes; the others stay on
KNOWN_FAILING with the causes they had (SMLib status 1001, the surface-of-revolution
check, rounds past the rim not built by subtraction).

The 851 table rows grade continuity again, on each round's seams to the faces it
rolls on, picked by points at the middle of its edge (the top front round's at
z = 8 on the front and y = -19 on the top, the arc's at rho 23 and rho 21, the
uprights' at their contacts). The default `blend` selection read G0 there because
it pairs a blend face with the contact faces of every edge in the feature, so where
a round ends square on another edge's contact face (a crease by construction) it was
graded as a tangent seam: a gap in the grader's seam selection, worked around here
by naming the seams. All seven rows pass.

fillets/1668-fillet-outer-top-edge-of-thin-wall-r7-past-inside-corner (and the
both-sides R7 case) now grade the volume at rel 1e-6 (0.04 mm^3), not the rig's
1e-3. The closed form is exact: V0 = 104 64 42 - 100 60 40 less the round's
section (1-pi/4) 49 along 104 plus its part over the hollow, the square
[25,30] x [35,40] outside the circle about (25,35), Int_sqrt24^5 (5 - sqrt(49-u^2)) du
= 0.0050679 mm^2 (a 0.0005 grid gives the same to 1e-9), along 100: 38458.896.
SMLib gives 38458.389, 0.507 mm^3 less: exactly that part over the hollow, which is
not material, taken anyway where the round opens its slit. The unit test's bound
was right; the case goes on KNOWN_FAILING with that cause. The both-sides case
passes at the tighter tolerance.

The round trip's volume moves from the STEP unit test to an import rig case

The shell unit tests that checked geometry become shell rig cases built through

(the pyramid made as two triangular prisms intersected, in place of
convex_polyhedron; the cavity integrated exactly over the cells where each moved
facet is highest, sharp inner corners as the ladder's tier 09), the box opened at
a bottom rounded R2 and R2.4 (refused: the rim would have no thickness) and R1.5
(built, exact volume), and the plate with a hole through its arc side. Four
action-matrix shells that regressed (issue-616's lid, the ring-cut frame, the
filleted shelled box shelled again, the up-down join) get small cases too. The

The fillet and chamfer unit tests that checked geometry become fillets rig cases,
built through commands with answers derived by hand (each method field gives the
derivation): a plate outline and a disc rim as tall as or past their wall, a
notched block's outline at R7 and R8, a cube corner as wide as its faces (refused,
and reduced), the 1668 wall at R7 alone and both sides, the 2852 U shell at R30
(refused, naming 25.24), the 851 knife edge (R2, chamfers 0.5/2/5 on three
constructions), the arc top edge at the full wall height and at 9.5, the 851
table of selections, the 556 top edge ending on the boss wall, the 2893
cylinder-rim chamfer refusals and the elliptical rim, seed 33's full round, the
sloped basin rim blends (single edges with exact volumes, loops with the slab's
box), and three action-matrix chamfers and fillets. fillets/851's three-edge
corner gets its volume (67.051 removed, re-derived on a grid; the engine test had
67.05). Chamfers whose leg runs off the face beside the edge are refused and rounds
past a face on its tangent side build, as the owner ruled on 2026-10-30. The cases
that fail today are on KNOWN_FAILING with their cause.
The unit tests are removed, except two cut to what no command can express: the

A colliding pair past the 16 pairs whose volumes are worked out, or past
the check's 256 body intersections, or whose intersection could not be
made, fell back to the sampled mesh depth for its deepest step. That
changed what deepest_step means without saying so. Such a collision now
answers deepest_step and volume_mm3 null and not_measured naming the
budget it ran past (or the intersection that failed), as compare does
since #9132; first_step, last_step and steps are exact and stay.
B pushed through A at 1000 samples overlaps it at about 330 samples, past
the 256 intersections: not measured, "the check's 256 body intersections
ran out". At the study's 16 samples it is measured, deepest at step 15.

motion.interference picked a collision's deepest step by the depth sampled
on the contact meshes (vertices, edge midpoints, triangle centres), and
worked out the exact shared volume only there. That depth depends on where
the mesh puts its points: since planes mesh as their boundary's triangles,
the arm turning into a block (rig case
assemblies/cov-motion-interference-arm-into-the-block) sampled 4.64 mm at 60
degrees and 2.0 mm at 90, and the check answered step 6 with 536 mm3. The
exact depth is 5 mm at every step from 60 to 90 degrees (both slabs are
10 mm thick), so depth cannot tell those steps apart.
The exact shared volume is now worked out at each sample a pair overlaps,
and the deepest step is the first with the most (a tie keeps the earlier
sample). The arm and block share 536, 807, 952 and 1000 mm3 at 60 to 90
degrees, so it is step 9 with 1000 mm3, at 10 samples or 19. depth_mm is
reported as before and documented as an estimate from the contact meshes.
volume_mm3 is null, and the step falls back to the sampled depth, when the
volume was not worked out at every sample (more than 16 pairs, or past the
boolean budget, raised from 64 to 256 now that it covers every sample).

Where two curves of a face touch or cross by less than the chord tolerance, halving their
chords never parts them, and the face was left to the lenient fill: thin_face_tests::
a_face_touching_its_own_edge_meshes (#1648), an arch dipping 2.8e-7 mm below its face's
bottom line, came out 0.659 mm2 against its boundary's 0.567 at tol 0.3.
After the halving rounds, a face whose boundary still crosses itself has each node that lies
within the chord tolerance of a crossing chord of another edge (strictly between its ends) put
onto that edge as well, the same point (edges::snap; the node is marked as snapped). In a face
that runs both edges, the snapped node takes the other's parameters, so the boundary passes one
point of its (u, v) twice (a pinch) and the chords meet there instead of crossing; the edge's
other faces get the node too, within the tolerance of their pcurve, so the mesh stays
watertight. Where the curves run within the tolerance for a stretch, the nodes either side are
shared in turn and the boundary runs out and back along one polyline (a slit). A node is not
snapped where the pinch would turn part of its loop inside out by more than the tolerance (two
curves crossing at an angle: the face is refused, as before). Nothing is loosened: the
crossing test and the triangulation's boundary check are unchanged.

A planar boolean leaves a cut-out's corner that touches another loop's corner as two vertices
a hair apart: in the sheet refold tests (doc sheet a_cut_out_on_one_side_of_a_bend_line... and
a_cut_out_with_a_corner_on_a_bend_line...), a triangle's corner 1e-8 to 5e-8 mm from the base's
corner on the bend line, both vertices of tolerance 1.05e-4. Their loops then cross by 1e-8 in
(u, v), which no constrained triangulation can keep, and the face was left to the lenient fill.
The boundary build already makes a vertex the face passes twice one point of its (u, v). Now a
vertex within the tolerance of another of the face's vertices (the larger of the two, at most
the chord tolerance) takes that one's parameters too, so the loops touch at one point, a pinch,
as at a shared vertex. Not for two vertices an edge of the face joins: the edge says they are
two points, however near (a_ledge_beside_an_edge_as_tall_as_the_setback_goes_with_the_strip
has a 1e-4 mm step, within the vertices' 1.18e-4 tolerance), nor at a pole.
Test changed, with the reason: thread_display_mesh_stays_on_its_surfaces checked every triangle
whose three corners lie at the core radius rc as one of the core cylinder, and wanted its centre
within 2 tol of rc. The flat end disc of the M10x1.5 thread (z = 12) has its corners a hair
apart too; joined, it is meshed strictly from its boundary (a plane, e39fbdebb), and one of its
triangles has its three corners on the rim, centre at r = 3.956, on the disc. The end-disc
exemption the test already makes for its radius check now covers this check as well.

uv::divide started every curved face from ceil(range / (pi/2)) lines, as if the parameter were
an angle. A spline's is not: SMLib holds a 90 degree bend as one rational quadratic span with
v in [0, pi/2], and the far pcurve of its boundary gives v = -6.7e-13, so the range is a
rounding over a quarter, the count rounds up to 2 and the bend gets a line at 45 degrees
whatever the tolerance (display_mesh_tests::a_small_bend_on_a_large_sheet_is_meshed_round:
3 angles across the bend at the chord tolerance instead of 2).
The division now starts from the whole range, and the limits refuse an interval that spans
more than a quarter turn of its iso-lines, read from the points as an edge segment's is
(edges::QUARTER_TURN: the half chords of an arc turning theta differ by theta/2, a closed
iso-line's by pi). On a revolved surface the parameter is the angle, so the lines are the
same as before; an iso-line within a millionth of the tolerance of one point (a pole) has no
turn to read.

The comb tool passed only the pick, so a comb's length and tooth count
could not be changed. While the tool runs, a card at the top left of the
view has Comb length (0.25x to 8x the automatic length, default 1x) and
Teeth (4 to 200, default 40), with plain-word tooltips; moving either
runs the comb again on the curves and edges already shown. New strings

`inspect.curvature_comb` read the display mesh for model geometry: an
edge's comb fitted a circle through every three points of the nearest
mesh polyline, a face's did the same on its iso lines' chord points. The
comb was jagged, changed with the mesh tolerance and ignored `density`.
- geom: `CurveEval::jet`, a curve's point, unit tangent and curvature
vector kN from its first two derivatives (lines and conics in closed
form, B-splines and NURBS from the basis functions' derivatives, a
traced intersection from both surfaces' normal curvatures along its
tangent, by Meusnier: kN lies in the plane of the two normals and its
component along each is that surface's normal curvature).
- kernel (curvature_comb.rs): the edge nearest a pick by the exact
distance to its curve (a periodic face's seam and poles left out),
`density` teeth at even steps of the edge's parameter; along an iso
line, the surface's normal curvature n.S_tt / |S_t|^2 along its normal.
`IsoLine` carries the running surface parameter's span.
- engine: edges and faces use them (and `inspect.minimum_radius` on
edges); new optional `length` multiplies the automatic scale. The reply
keeps its shape.
Tests: a circle edge reads 1/R to 1e-9 at Coarse and Ultra display
quality alike, with `density` teeth; an extruded ellipse's edge matches
ab/(b^2 cos^2 t + a^2 sin^2 t)^(3/2) at every tooth, a/b^2 and b/a^2 at
the vertices; a cylinder face's rings read 1/R and its lines 0; `scale`
and `length` set the teeth's length; curve jets on every record kind.
The existing cylinder-edge check tightens from 0.5 mm to 1e-9.

corpus_designs_rebuild_with_the_same_names_and_references compared every
corpus design with a text record of each body's face and edge counts and its
full name list, last written from truck's output (a55196e7a); 110 designs
differed only because SMLib keeps whole faces truck split in pieces. Those
counts and names are the kernel's, not an outcome.
The test, renamed corpus_designs_keep_their_references_and_name_alike_every_build,
now asserts invariants only, with no record:
- every design loads; one that does not is a failure naming the design and
the step (oracle/83-boundary-loop-thicken: surface.thicken, SMLib status
1001), not a record line;
- every name a design stores (fillet and chamfer edges, faces a feature
picks, a sketch's face, sheet metal edges) finds a face or edge: none
`gone`, no sketch face `lost`;
- two builds give the same name -> face map: each named face's area and
centre and each named edge's length and middle (to 1e-6 of their size), and
the same face or edge found for every stored name.
The design already exempt for unstable piece order
(regressions/closed_sweep_torus_cut) is still only printed for the second.
On develop it fails on two designs: oracle/83 above, and
regressions/cut_up_to_face_leaves_skin, whose Extrude13 face
`F47:top#[...]` finds nothing (the truck-era record had it `gone` too). All
159 designs name alike in both builds. The records in tests/naming/ are no
longer read; CONTRIBUTING no longer asks to re-record them.

ordinary_curved_bodies_keep_a_practical_sampling_step asserted
ContactGeometry.step > 1.0, an internal sampling step derived from the

Ellipse a = 10, b = 4, extruded 5: area = 2 pi a b + 5 P, P = 4a E(e),
e^2 = 1 - b^2/a^2. By the Gauss-Kummer series, P = pi (a + b) sum_k
(binom(1/2, k))^2 h^k, h = ((a - b)/(a + b))^2 = 9/49: P = 46.026225191330
(a 200000-point midpoint integral of sqrt(a^2 sin^2 + b^2 cos^2) agrees to
1e-13). A = 80 pi + 230.131126 = 481.458538 mm^2, asserted to 1e-4; a faceted
side would be short of it. Only the top and bottom are planes
(face_types.plane = 2, merged pieces counted once).
The fit spline closed by a line: the planes are its top, bottom and the line's
side (face_types.plane = 3); its volume stays checked against the profile

a_mirrored_or_patterned_sheet_body_is_sheet_metal_with_its_flat_pattern
(1171c4c2a) expected the mirrored copy's model turned over: the same outline,
its bend down and its pocket on top. That describes a SheetBody::moved that
never landed. The code on develop is SheetBody::copied (d9d6af51c, #3354): a
mirror moves the frame and mirrors the flat x -> -x with the same thickness
side, the opposite hand's blank with each bend turning the same way, which
a_mirrored_sheet_copy_is_the_opposite_hand_with_the_mirror_image_flat_pattern
asserts on an asymmetric bracket. The YZ mirror keeps z, so a pocket cut from
below stays below and the flange on y = 0 still turns up: the flat pattern
reads blank x 0..100 -> -100..0, pocket x 20..30 -> -30..-20, side bottom,
bend up.
The test now asserts that: the same flat size, the outline and the pocket
outline equal to the source's with x negated (to 1e-6), pocket side bottom and
bend up on both. The volume doubling, the bend table and the flange rebuilt
on the copy (point containment) stay.

a_trays_faces_have_readable_sheet_names_that_follow_its_size asked for

Now: there is an unnamed face and every one is the hole's wall (r 3.3), and
the back flange's far rim point lies on that rim: z = 30 and 199 <= y <= 200
(the flange 1 thick, its outside at y = 200), 0 <= x <= 400, to the 1e-3 the

The ball 2 from the back face y = 0 and from the r 21 wall about (62 1/6, -21)

0.004 x 0.001 step. The kept test's fillet bound goes from 0.5 to 5e-4 of

cut_whose_end_touches_an_arc_side_leaves_no_sliver compared the touching cut's
face count with a clear cut's, a count of how the kernel splits its faces. It
now compares what the two parts are.
The plate's arc runs from (0, 20) through (-10, 10) to (0, 0): centre (0, 10),
r 10, so it reaches x = -10 only at y = 10. The r 5 cut along x about
(y, z) = (12.5, 12.5) spans x -10..7.5 (touching) or -10.1..7.4 (clear). Both
open the same patch of the arc; the slice x 7.4..7.5 lies wholly inside the
plate (y 7.5..17.5, z 7.5..17.5 in 0..20 x 0..27.5). So
V(clear) - V(touching) = pi 5^2 0.1 = 7.853982 mm^3
A(touching) - A(clear) = 2 pi 5 0.1 = 3.141593 mm^2 (the hole wall; the
floor disc is the same)
both to 1e-4 (the measure integrates the exact faces to 1e-8). A sliver of the
arc left where the end touches adds about a square millimetre of faces.
Seed 14's half (the fuzz generator's seed, then a shell) is pinned as its own

and 8dc344d22 used: rim rounds meeting at a concave corner beside an
unpicked sharp edge are mitred by default (a user who wants it swept rounds
the corner edge too; a swept corner with a sharp inner edge is a future
option). SMLib's swept result is the defect, so both tests now expect the
mitre and fail today on it.
rounds_that_fit_are_closed. At depth u the section is the outline moved in
by d = r - sqrt(r^2 - (r - u)^2) with every corner mitred: the area less
L d, plus d^2 at each of the six convex corners (the two strips overlap in
a d x d square) and less d^2 at each of the six concave ones (the mitre
also takes the d x d square beyond both strips), the overlap of the two
spandrel prisms being r^3 (5/3 - pi/2) per corner over the round. Six and
six cancel, so both ends remove 2 L r^2 (1 - pi/4) with L = 107.6:
11.545566 (the swept corners gave 11.514718).
fillet_tabbed_plate_outer_loop_and_partial_selection_after_hole. Where both
sides of a concave corner (+-4, sqrt(609)) move, the moved R25 arc and the
moved side x = 4 - d now meet where they cross,
y = sqrt((25 - d)^2 - (4 - d)^2), as where only one side moves; the swept
arc branch goes. Check: A(0,0) - A(d,d) agrees with the Steiner form for a
mitred outline, L d - d^2 (pi + theta - 2 tan(theta/2)), to second order
(17.190976 against 17.190968 at d = 0.1; the arc's curvature moves the
mitre point at third order, which the Green's-theorem area has exactly).

a_strip_off_a_curved_face_is_ruled_to_its_far_curve lifted the free
strip's handles 1 mm and wanted the strip's bounding box to rise, which it
need not (the far curve's corners are fixed and the box's top may be
elsewhere). It now checks what the handles do: the plan's far curve takes
the lifted handles as its interior control points and keeps its corners,
so it rises by 1 - R0 - Rn inside; the built strip has that curve for an
edge (33 points of it within 1e-3 of the strip's edge polylines at 1e-4),
and its middle, risen more than 0.1, is more than half that from every
edge of the default strip.
It fails today on its premise: the strip's edge (the cup's straight rim at
x = 14) is a line, so its far curve, on the edge's degree and knots, has
no interior control points, and ruled_far_handles gives an empty list
(the old witness passed nothing to move). A real gap: the far curve of a
strip whose rulings turn along a straight edge is the chord between its
corners.

rounded_slot_exports_cylinders required no B_SPLINE_SURFACE, four
CYLINDRICAL and two TOROIDAL surfaces; ramp_cut_slot_exports_sheets
_bounded_by_their_faces five CYLINDRICAL and two B_SPLINE (SMLib keeps one
more round an exact cylinder). Which kind a face is written as is the
writer's choice; what #612 and #1198 were about is that no surface reaches
past the part. Both keep that (every CARTESIAN_POINT's x within [0, 60],
control points and placements included) and their round-trip volume: the
first against Pappus, the plate (800 + 100 pi) 4 less (1 - pi/4) along
the straight edges and the arcs at 10 - r (10 - 3 pi) / (3 (4 - pi)), at
1e-3; the second against the exported body's at 1e-4. Both pass today.

Three history tests pinned truck's sewing in tallies:
- shell_of_a_painted_body wanted changes [0, 2, 8, 0, 5], the side faces
split across the rim's level; SMLib's shell leaves them whole. It now
checks what paint follows: the painted face 0 comes through as exactly
one face (its geometry checked against face 0 by verified()), and each of
the five inner walls is one Generated Offset of the face it lines, the
open top none, as shell_lines_the_walls_with_offsets has it.
- fillet_after_box_cuts wanted the painted cuts to leave faces in pieces
and the fillet's edges to meet merged faces; it keeps the outcome for
every cut on both blocks: the round stands in place of the picked edge,
and composed with the cut the history holds over the block and the tool.
merged_meetings has no use left and goes.
- surfaces_keep_their_faces wanted every stitched face Kept; whether
sewing changes a face's class is not the contract. It now checks each
stitched face has one origin, the face it was sewn from (geometry checked
by checked()), the five walls the open box's faces 0-4 and the lid the
patch, and the four seams naming two edges each.
split_a_face is left as it is (the owner's ruling: a face whose boundary
only gained a vertex is Kept), failing until SolidCraft's split history
says so ([3, 2, 2, 0, 0] against [5, 0, 2, 0, 0]). The three tests above
pass today.

rounded_shell_planar_roles_are_exact_distinct_and_transformable required
the four outer r6 rounds to be coalesced extrude sides (face_was_coalesced:
SMLib's round is not one any more), no floor-height seam between corner
faces, 19 faces in the cup and in its STEP copy, and the volume of a 1e-4
mesh within 0.2. It keeps what the roles are for: the right wall's role
resolves to the face at x = w/2 and the floor's to the face at z = t, both
still after the transform; each straight outer wall is one full-height
face, in the cup and in its STEP copy; and the cup's volume is exact.
Proof. The box w x 60 x 30 with its four vertical edges rounded r6 is
(60 w - (4 - pi) 36) 30; shelled t inward, open at the top, its inside is
the box moved in by t with its corner rounds at 6 - t:
((w - 2t)(60 - 2t) - (4 - pi)(6 - t)^2)(30 - t). Graded on SMLib's
volume (integrated on the surfaces, to 1e-8) at 1e-6. It passes today.

a_small_bend_on_a_large_sheet_is_meshed_round also pinned the chord-only
mesh (exactly two stations across each bend, its sag over 0.29 r) and
required every flat side face to keep the chord-only mesh's triangle count:
facts about another mesh, not what the display shows (the chord-only mesh
now puts three stations across the r1 bend). It keeps what the display
mesh must do: each bend a quarter turn in more than five facets, each
turning at most DISPLAY_ANGLE, sagging at most r (1 - cos(angle / 2)) and
less than the chord tolerance. It passes today.

a_five_sided_window_fills_g1_and_through_a_point required five faces and at
least 15 edges (five patches about a centre); a_hexagonal_rim_fills_through
_a_point... required (6, 18). How many patches a fill is made of is the
fill's own business: both keep their outcome checks (check_face: the rim's
own edges, within the face tolerance, a clean mesh; G1 to the wall within
0.1 degree; the point on the surface; the sealed cup holding more than the
plain fill's).
Both still fail on outcomes: the pentagon's fill through a point has a
folded triangle in its mesh, and SMLib's stitch refuses the hexagon's fill
through a point (its control net doubles back on itself, a cusp in a
curve).

a_crowned_patch_fills_its_middle_and_keeps_its_edges checked only that NaN,
infinity, 3.01, -0.91 and 1e300 are refused; it now checks why: "a patch's
crown must be between -0.9 and 3" (patch_edges_crowned's range test).
The bump check is left as it is. The audit proposed measuring it in model
space along the loop plane's normal, but it already is: both patches are
height fields over the same plane on the same parameters, so the distance
between their points at the domain's centre is the bump along the normal,
and the record's domain is the fit's box in mm (diagonal 52.5). The crowned
patch's middle rises 7.656 where the documented crown x size is 13.125:
the crown's bump reaches 7/12 of what patch_edges_crowned promises on this
pentagonal cup (geom's own test of fill_loop, on a fine hexagon net, gets
it to 1e-9), a real gap, still failing.

collapsed_taper_mesh_stays_accurate_as_tolerance_decreases compared each
display mesh's volume with the taper law's integral,
6000 - (1 - pi/4) 40 integral r^2, at 1e-4: the built fillet removes about
10 mm3 more than that (5212.9 against 5223.1) at every tolerance, so it
measured the fillet, not the mesher. It now holds each mesh to the B-rep it
meshes: a mesh within its chord tolerance of the faces has its volume
within area x tolerance of the exact one (SMLib's, integrated on the
surfaces to 1e-8), the bound fillet_mixed_arc_and_line_removed_volume
_converges uses. It passes today.
taper_follows_the_room_along_the_edge keeps its law and closed-form
volumes (the 10 mm3 against the law is the failure it still shows) and
drops the two internal checks at its end (no unmeshed face, a face with
three vertices) for the outcome: the wedge's tapered fillet is valid.

the_arc_rounded_after_the_back_edge_matches_both_together ran
one_then_the_other(BACK, arc_top()) as a test of its own. It is the same
check as every pair of a_round_ending_in_an_earlier_round_matches_both
_together (the round in sequence against both together, within the
display meshes' 5e-3), which had only the other order (arc_top(), BACK):
the pair joins that list and the separate test goes. Nothing is loosened.
Today the list fails before it reaches the pair: SMLib fails the arc's
round after the long front edge's (status 1001); the back-then-arc pair
failed the same way on its own.

rounds_that_fit_are_closed counted faces (the input's plus one per picked
edge: 38, where SMLib makes 50 with its corner faces). It now keeps
validity and no crossed loops and holds the R0.5 rounds on all 24 end-face
edges to the exact volume.
Proof. The part (plate 14 x 21.5 x 10, block 14 x 9.948 x 10 on it, the
5.2 x 7.1 window through both along x) is
14 (215 + 10 (b - a) - 36.92). At depth u into an end face's rounds the
section is that face's outline moved in by d = r - sqrt(r^2 - (r - u)^2),
each edge parallel to itself: the area less L d, L = 2 (21.5 + 20) +
2 (5.2 + 7.1) = 107.6 (the stepped outline's perimeter is its box's), plus
d^2 at each of the six convex corners (two rounds mitred), less pi d^2 / 4
at each of the six concave ones (the two shoulders and the window's four
corners: rounds meeting at a concave corner beside an unpicked sharp edge
are swept round it, the owner's ruling of 2026-10-30). The wall between
window and block side is 1.256 > 2 r, so the offsets stay apart. Over the
round the integrals of d and d^2 are r^2 (1 - pi/4) and r^3 (5/3 - pi/2),
so both ends remove
2 (L r^2 (1 - pi/4) - (6 - 6 pi/4) r^3 (5/3 - pi/2)) = 11.514718.
Graded at 1e-7 of the part's volume. It passes today (aarch64, SMLib).

issue2422_vertical_after_separate_bottom_rounds compared the face count and
volume (within 0.05) of the vertical round, picked with and without its
bottom mitre, against the same round picked alone, and required every face
meshed. It now holds each of the three picks, on the 40 x 80 x 27 box and
on the same shelled 1 mm open at the top, to the exact volume; the corner
probes stay.
Proof. Horizontal sections, s up from the bottom. Below s = r the four
separate R2 bottom rounds (mitred at the corners) leave the rectangle
moved in by d = r - rho, rho = sqrt(r^2 - (r - s)^2), and where the
vertical round meets them (a sphere octant) its corner is a quarter disc of
radius rho: (L - 2d)(W - 2d) - (1 - pi/4) rho^2. Above, LW - (1 - pi/4) r^2.
With the integrals over the bottom r of rho (pi r^2 / 4), rho^2 (2 r^3 / 3),
d (r^2 (1 - pi/4)) and d^2 (r^3 (5/3 - pi/2)):
V = LW r - 2 (L + W) r^2 (1 - pi/4) + 4 r^3 (5/3 - pi/2)
- (1 - pi/4) 2 r^3 / 3 + (H - r)(LW - (1 - pi/4) r^2) = 86174.445361;
with four such corners it is issue1557_all_vertical_corners_match_analytic
_volume's formula exactly. The shell's cavity, 38 x 78 x 26, is clear of
both rounds (along the corner's diagonal the R2 arc stays 2 - sqrt(2) in,
the cavity's corner is 1 in), so the cup is V - 77064. Graded at 1e-6.
Today SMLib's check refuses the bottom rounds' result (edge and vertex
tolerance 0.97 against 0.01), as before.

fillet_tabbed_plate_outer_loop_and_partial_selection_after_hole only
checked that every subset of the R25 tabbed plate's seven top-outline edges
builds and stays inside the plate. It now first holds the hole's rim round
and the three selections that end only at the plate's sharp concave
corners (the R25 arc's two halves, the tab's tangent run of sides, R2
corners and top, and both) to their exact removed volume; the sweep over
all 127 subsets stays as it was.
Proof. The outline's area A(da, dt), the arc moved in by da and the tab's
run by dt, each element parallel to itself, by Green's theorem: an arc
about c of radius rho from a to b gives
1/2 (rho^2 (b - a) + rho (cx (sin b - sin a) - cy (cos b - cos a))), a
segment p -> q gives 1/2 p x q. At a concave corner (+-4, sqrt(609)) where
only one side moves, the elements meet where they cross (the round runs
into the other wall: the section is the union of the two sides' half
regions); where both move the corner is swept, an arc of radius d about the
corner, traversed clockwise from the arc's normal to the side's (the
owner's ruling of 2026-10-30 for rounds meeting at a concave corner beside
an unpicked sharp edge: the profile swept round the corner edge). Checks:
A(0, 0) = 312.5 (pi + 2 theta) + 4 y + 8 (cy - y) + 8 + 2 pi (disc sector,
triangle, tab, R2 corners), and A(0, 0) - A(d, d) = L d - pi d^2 by the
Steiner formula for the swept offset (total smooth turning 2 pi + 2 theta,
the two swept corners -theta each), agreeing to 1e-15 at d = 0.1, 0.3,
0.5; A(0, 0) - A(0, d) agrees with a 0.004 mm grid to 2e-6. The round's
section at height r sin(phi) into it is the outline moved in by
d = r (1 - cos phi), so it removes the integral of
(A(0, 0) - A(d)) r cos(phi) dphi over [0, pi/2] (midpoint rule, 8192
steps, converged to 1e-7 against 4096). The hole's rim round is Pappus:
(1 - pi/4) r^2 about the axis at 1.5 + r (10 - 3 pi) / (3 (4 - pi)).
Graded at 1e-5 of the removal, the bound the D prism's rounds are held to
(the blend surfaces are SMLib's fits).
Today the three selections build with these volumes (aarch64, SMLib); the
sweep still fails where a subset ends a round at a tangent joint (the x = 4
side without its R2 corner): SMLib cannot end a blend inside a tangent
chain, "the blend cannot end there".

The owner's blend-overflow ruling of 2026-10-30: a chamfer whose leg runs
off the face beside its edge over another face is refused as too large,
naming the largest size that fits (a 2 mm chamfer on the basin's 1 mm rim
would lower the slab's front face from 30 to 29.382); a full-width chamfer
stays refused. Two tests wanted those chamfers built and cut from the slab:
- chamfer_wider_than_sloped_basin_rim_is_cut_and_a_full_width_one_refused
becomes chamfer_wider_than_sloped_basin_rim_is_refused_naming_the_largest:
(margin, d) = (1, 2), (1, 3), (0.5, 4) and the full widths (0.5, 0.5),
(1, 1) are TooLarge, the body unchanged, and the message names a largest
size just below the rim's width: the full width is refused, so the fit
search (three significant digits of the size asked, step
10^(floor(log10 d) - 3)) ends one step below it, in
[margin - step, margin). The removal formula for the cut chamfer
(basin_rim_chamfer_removed) has no use left and goes.
- equal_slope_rim_loops_stay_inside_the_material: the 2 mm chamfer of the
1 mm rim's loop is refused the same way (largest in [0.999, 1)); the R4
round (tangent side, builds) and the 0.5 blends stay.
The half-width chamfer on each rim, which only had to take something off,
now takes its exact volume. As in chamfer_sloped_basin_rim: the triangle
with legs d on the top and d down the wall towards (20, 10) (run
20 - margin over the 20 drop) has area d * drop / 2 with
drop = 20 d / sqrt((20 - margin)^2 + 400), and the chamfer's length at
depth h is 60 - h between the end walls x = 20 + (30 - z) / 2 (planar:
x depends on z only), so it removes d * drop / 2 * (60 - drop / 3);
graded at 1e-8 as that test is.
Today SMLib refuses the chamfers as too large, but the message does not
name the largest that fits yet ("the chamfer is larger than the faces
beside its edges allow"), the SolidCraft change issue_1080's R30 test
waits for too.

The owner's blend-overflow ruling of 2026-10-30: a round that runs past
its face on its tangent side is built on the face continued and cut from
the part, keeping its radius. loop_fillet_as_tall_as_its_wall_consumes_it
still wanted R2.001 and R2.5 on the R13 x 2 disc refused as taller than the
wall; they now must build, valid, with the exact volume.
Proof. The round's section in (rho, z) is the r square at the top edge
outside the circle about (13 - r, 2 - r), clipped to z >= 0. With
t = z - (2 - r) = r sin(theta), the round's inner radius is
rho(theta) = 13 - r + r cos(theta), theta from asin((r - 2) / r) to pi/2,
and the disc keeps pi (169 * 2 - integral (169 - rho^2) dz), dz =
r cos(theta) dtheta (midpoint rule, 20000 steps). At r = 2 it is Pappus,
2 pi 169 - (1 - pi/4) 4 * 2 pi (13 - c), c = 2 (10 - 3 pi) / (3 (4 - pi))
(checked to 1e-9 in the test); at r = 2.5 it is 957.692239 mm3, the
ruling's number, the same integral as
rounds_past_the_bottom_of_a_wall_are_cut_from_the_part's. Graded at 1e-6
as that test is.
Today SMLib fails the R2.001 round (status 1001): a convex round past its
face is not yet built by subtraction, the cause fillets/KNOWN_FAILING gives
4782 and 5158.

fillets/324-fillet-over-hole-overlap's body, but cut its hole with a cylinder
longer than the block (z -1 to 11) where the rig extrudes a sketch circle
flush. The new case fillets/324-fillet-over-hole-cut-by-overlong-cylinder
builds it that way (solid.cylinder, base z -1, height 12, cut) and holds it to
the same hand-derived answer: block 40x20x10 less the r3 hole at (20, 14.5)
(282.74) less the R4 round on the top edge at y = 20, 40 (16 - 4 pi) = 137.35,
plus what both remove, the integral over y in [16, 17.5] of
(4 - sqrt(16 - (y - 16)^2)) * 2 sqrt(9 - (y - 14.5)^2) = 0.375830 (re-derived
with the substitution y = 17.5 - s^2, 200000 steps):
V = 8000 - 90 pi - 40 (16 - 4 pi) + 0.375830 = 7580.287315, and G1 on the
blend. It passes today (aarch64, SMLib), as the flush case does, so it needs no

Stale since 84bd2daad (the Fillet feature rounds each pick's tangent chain). After a and b are
rounded at 2 mm and meet in a mitre, the mitre's seam leaves c's end along c, so c's chain is c
and the seam; rounded at 2 mm, as the issue1557 tests pick, the corner is a sphere octant.
Proof: the 20 mm cube less its three rounds, each (1 − π/4) r² over its 18 mm straight part, and
the corner's 2 mm cube less the octant, r³ (1 − π/6): 8000 − 3·(1 − π/4)·4·18 − 8·(1 − π/6) =

Stale since 84bd2daad, which gave solid.fillet each pick's tangent chain by default. After the
long top front edge is rounded, the front-left upright meets the round's end (the quarter circle

the second fillet rounds the upright and the top-left edge. The "together" fillet picks the
three edges ([20, -21, 10], [0, -21, 5], [0, -10, 10]); one by one and together remove the same
volume within the display meshes' 2e-4 (it read 60.649 vs 43.185 with two picks).

tangency-labs/smlib#64 builds a tapered wall that closes partway up (its neighbours meet above
its apex), so the 0.2 mm slot of a 10 mm square tapered 10° out over 2 mm now builds where it
was refused. The test, renamed for what it checks, asserts the slot's solid is valid with its
exact volume and keeps the ring's refusal (its 0.3 mm hole closes entirely).
Proof of the volume, t = tan 10°: every wall moves out of the material by z·t at height z. The
square grows to 10 + 2zt, so without the slot ∫₀² (10 + 2zt)² dz = ((10 + 4t)³ − 1000)/(6t).
The slot narrows to 0.2 − 2zt and keeps its length 8 (its end wall and the square's side both
move up by zt); it closes at z = 0.1/t = 0.567 and takes ∫ 8 (0.2 − 2zt) dz over 0..0.1/t =
0.08/t. Volume ((10 + 4t)³ − 1000)/(6t) − 0.08/t = 213.984095421783; measured to 1e-6.

tangency-labs/smlib#63 raised SMLIB_CURVE_MAX_CURVES from 4096 to 16384; CURVE_MAX_CURVES
follows it, so a profile of 5000 segments (a modelled thread, a fine polygon) extrudes:
kernel tests::measure_of_a_body_with_many_faces passes (5002 faces, 15000 edges, 10000
vertices).

- #63: a knife edge (two faces tangent along it, folding back) rounds to the ball touching both
faces back from it; a curve list takes up to 16384 curves (SMLIB_CURVE_MAX_CURVES); a stitched
solid is a nested solid, its cavities void; booleans pair each face only with the faces whose
box comes near its own, the closure test of a new face searches from both its sides, and a new
edge from a faceuse shell to a wire keeps the faceuse shell: a row of Menger sponges joins in
near linear work.
- #64: a tapered wall that closes partway up ends at its apex, its neighbours meeting above (it
was refused as SMLIB_ERR_WALL_CLOSES); a round of revolution offset in past its radius has no
offset; a round along an arc turns from its start section, not from the arc's frame.
- #65: capi tests, the Menger row join counts its work (smlib_work_counters) instead of timing it.

tapered_extrude_swallows_a_short_tip expected the prismatoid whose two tip
corners run straight to the top's tip (h/6 (A0 + 4 A_mid + A1)), the solid
the old offset-and-rule construction built: its tip triangle leans about 40
degrees, not the 5 degree taper. With every wall drafted 5 degrees the tip's
wall is a triangle that closes where the long sides meet across it, at
z* = 0.126237833 (offset 0.011044379), and above that the long sides meet
along a ridge. The section at height z is the profile's lines moved in by
z tan(a): a quadrilateral below z*, a triangle above, each area quadratic in
z, so Simpson's rule on each piece is exact: V = 72.883284979193. The old
value, 72.882657253174, is 8.6e-6 off, past the test's 1e-6. SMLib's
DRAFT_CORNER_ROUND path builds exactly this solid (72.883284979193, 6 faces);
the default curvature rule still refuses it (SMLIB_ERR_WALL_CLOSES at
(20, -0.01, 0)), so the test fails until the fork builds a wall that closes
partway up.

shell_thicker_than_a_rim_is_refused expected the "rim or ledge" refusal from 9508ee749,
added because truck's face offset turned the top face inside out and returned a body of
about twice the volume. SMLib builds the exact sharp-edged offset, and its volumes are the
closed form, so the test now checks those (renamed
shell_of_a_basin_past_its_rim_keeps_the_rim_solid).
Proof. Slab [0,100]×[0,60]×[0,30]; pocket lofted from x 20..80, y 4..50 at z 30 to
x 30..70, y 20..40 at z 10, its sides the planes x + z/2 = 35, x − z/2 = 65,
y + 0.8z = 28, y − z/2 = 35 (normal lengths √5/2, √5/2, √1.64, √5/2). Shelled open at
z = 0 by t, the cavity is the slab shrunk by t (x t..100−t, y t..60−t, z 0..30−t) less the
pocket grown by t (each plane moved out by t·|n|, floor z = 10 − t). For t ≤ 6 the grown
pocket stays inside the shrunk slab in x and at the back (50 + 0.618t ≤ 60 − t); its front
reaches y = t at z0 = (28 − (1 + √1.64)t)/0.8, below 30 − t from t ≈ 2.70 (the rim stays
solid above z0). With W = 30 + z + √5 t,
grown(t) = ∫[10−t, z0] W (7 + 1.3z + (√5/2 + √1.64)t) dz + ∫[z0, 30−t] W (35 + z/2 + (√5/2 − 1)t) dz,
V(t) = 180000 − grown(0) − (100 − 2t)(60 − 2t)(30 − t) + grown(t),
grown(0) = 33866.667, so V(1) = 17105.6240415, V(4) = 63560.2492284,
V(6) = 90113.9202101. SMLib measures 17105.6242, 63560.2492, 90113.9203 (≤ 1e-8
relative). The test computes the closed form and checks each shell to 1e-6, with the
centroid inside its box and on x = 50 as before.

The test offset the sphere's top patch to get a fitted B-spline sheet. That held on truck,
whose sphere came in several patches and whose sphere offset was fitted. On SMLib the
sphere is one face: offsetting it closes up, so it is a solid by design (surface_offset.rs,
"Faces that close up make a solid", and its test a_sphere_is_fitted_and_refused_past_its_centre
asserts exactly that), and SMLib's offset is exact, a sphere of radius 22 with no control
points, which surface.fair refuses. Body::is_surface was right: the record lists the offset's
closed shell as the outer shell of a material region (Parts::canonical), so it is a solid
whether read from edge uses or from regions.
The test now fairs the patch on the non-planar rim of a box cut by a sideways cylinder (the
cover in patch_trim_thicken_and_stitch), a one-face B-spline sheet: energy 0.7185 → 0.6938 in one
step, edges unmoved bit for bit, undo/redo/reopen and the refusals as before.

hostile_params_never_panic built a box, a sketch and a rectangle afresh for each of the ~3000
calls it makes per command. SMLib serialises every call behind one process-wide lock, so those
boxes were built one after another whatever the number of threads: 20 threads made 4000 boxes
in 7.8 s, one thread 200 in 0.31 s (1.5 ms each). The fixture was nearly all of the test's time
(8814 of 8823 thread-seconds over the first 72 commands on the aarch64 box; the commands
themselves 9 s, none over 0.5 s), and the test took 2195 s in develop CI.
It now builds that model once per command and gives each call a copy of the session with its
design, model, undo, redo, open sketch and log, sharing the bodies as undo does. Every command
still gets every parameter name with every hostile value, from the same starting state. A new
check runs Cancel Sketch, two undos and a redo on a copy and on a session built afresh and
finds the same designs, with the copied session untouched.

encode_native_body turned the whole saved record into a serde_json
Value (a map with an owned key for every field of every face, edge,
curve and pcurve), checked it, counted it, then wrote it out. Building
that tree was most of the cost: on the Menger level 4 sponge (3 tools,
--save) the 101 bodies the model cache encodes, 535 MB of encodings,
took 24.1 s of encode_native_body, 20.8 s of it in to_value.
binary::write_serialized is a serde Serializer for the tagged binary
format: it writes each value as it is serialized and applies the same
checks as it goes (nesting, string and array budgets, floats within
1e12, the value budget, the size limit). An object's entries are put in
key order when it closes, as the JSON map held them; floats that are not
finite are null, as to_value made them. The bytes are the same: a test
encodes plain, blended, cut, extruded, painted, split, open, round and
far-placed bodies both ways and compares them, and all 101 Menger bodies
(6 to 28 412 faces, 15 kB to 68 MB) encoded both ways in one run were
byte for byte the same. The JSON-value writer stays for the tests that
build hostile records.
Menger L4 3-tool --save, two runs each: encode_native_body 24.1 / 25.3 s
before, 3.0 / 3.0 s after (the longest call 1.34 s -> 0.29 s); the run
41.2 / 41.4 s wall before, 39.1 / 39.2 s after (the encodings run on
16 threads).

A To Object extrude to a curved face runs its tool through the target and
cuts the target out of it. The SMLib boolean carries no extrusion face
sources (they stood for the untrimmed profile), so sheet_tool_span, which
read the tool's depth and footprint only off its extrusion caps, gave up
and the intersect was refused as unrepresentable.
The tool's current geometry says what it is: the kernel's prism
certificate (prism_measure, the one component copies are compared by)
reads off the exact record whether a body is a uniform prism along a
direction, its two cap levels and its section of lines and arcs. It is
now public as certified_prism_section, and sheet_tool_span uses it when
the caps don't certify the tool: the levels are the depth, the section the
footprint the To Object cut is bounded by. A tool trimmed to something
that is not a prism (a curved roof over it) is still refused.
partial_depth_intersect_curved_to_object_preserves_current_trimmed_cap_footprint
passes: the tool is the square 20 ... 30 less the pin's circle (radius 2),
z 0 ... 1, 100 - 4π, as the test's own witness extrude measures it. A
kernel test reads that section off the trimmed lump.

The refusal "capture the source occurrence position before generating a
legacy face profile across components" lost its test when Offset Face got
an exact history name (b6c3bf3c5). A half of a box's top that Split Face
divided still has neither a construction certificate nor an exact history
name, so Extrude from that face, in a component whose occurrence has an
uncaptured move, takes the legacy path and is refused there; the document
and the pending moves stay as they were.

end_at_wall takes the plate's end strip off a wall that stands on part of
an edge of the fixed face: the strip's two corners and its two edges go.
They were filtered at their places in the face's lists, counted from the
bend's edge, which pairs corner j with edge j only while the places do
not run across the lists' start. SMLib merges the plate's end strip and
both walls at x = 100 into one L-shaped face whose loop starts on the
strip, so the corners left were each followed by the next one's edge:
the bend's edge took the wall end's face and the wall end took the
plate's. The bend then ran the wall's full width and no relief cut it.
Both lists are now kept counted from the bend's edge.
a_wall_on_part_of_an_edge_meets_a_wall_at_a_relieved_corner_and_is_relieved_at_its_end
passes: bends [22, 92] (was [26, 96]). From the geometry: T 2, R 2, the
setback R + T = 4 on the plate from y = 0 and from x = 100; the round
corner relief 8 across is centred on the setbacks' corner (96, 4), so it
takes 4 off the end of each bend there: the long bend from x = 0 to
96 - 4 = 92, the short one from y = 4 + 4 = 8 to 30, 22 long.

The kernel switch broke these tests only through their counts, which record how a kernel splits
faces rather than whether the result is right. Each now checks its intent:
- a fitted circle is the exact circle (centre, radius, a full turn), not "one segment";
- the tight bend sweeps a valid solid of Pappus' volume, πr²(40 + 5π/2), not a count of faces,
edges and vertices;
- the Pi case keeps each outer side one face, stays valid after every feature and rebuilds the
same topology at 32 whether built there or edited there, without a hard-coded table of totals;
- a certified paint stays on the wall's radius and covers as many faces after an edit, a copy
and reopening as when it was painted;
- the offset sleeve and the extended strip are checked by their exact areas only.

saved_curved_strip_projection_is_lost_after_exact_wall_coalescence built its "old" strip by
cutting the cavity raw (paint turning off the construction shortcut), where truck sewed the cut
slab by slab and split the outer round at the cavity's floor. SMLib cuts without slabs: the raw
cut's round is one face, so there was no piece to save a projection on, and the test stopped at
"must have a piece suffix". The link is now what such a build saved, written out: the face name
`F2:blend:F1:+x|F1:+y#1` (the lower piece, numbered up its spread) and the piece's projection on
YZ, the rectangle y 24..30, z 0..2 (the quarter round from (40, 24) to (34, 30), its arcs and
straight sides), 12 mm³ when extruded 1. The current wall is checked to be one face with that
stem and no planar authority.
The test still fails: the link is found on the whole wall ("was split; using the nearest
piece"), not lost, and the strip's material grows to 6 × 30 × 1 = 180 mm³. project.rs takes a
missing piece as removed only on a certified planar or coalesced face, which truck's shell
made and SMLib's does not. That is a persistent-name decision for the owner (see the PR).

fillets_on_tapered_bosses_saved_before_still_find_their_edges compared the part with
69454.885209 mm³, what the truck build that saved it measured. In closed form: the 80 × 40 × 20
block (64000); the 20 × 20 boss 10 high tapered 5° in, a frustum to a 20 − 20 tan 5° square
(3660.251034); the Ø16 boss tapered alike, a cone frustum to radius 8 − 10 tan 5° (1798.751833);
less the R1 round on a sloping corner, the corner's section r²(cot φ/2 − (π − φ)/2) at its
dihedral angle φ = 90.435° times its length between z = 20 and 30 (2.124401), and the R0.5
round all round the cone's top, the section at the rim's 95° turned about the axis by Pappus
(1.928463): 69454.950004. SMLib's part measures 69454.950004.
The test still fails before that check: Fillet2's saved edge `F4:side:c1#1|F4:top#[F4:side:c1]`
names a half of the cone wall truck built, which SMLib builds whole, so it is found with a
"was split" warning (a persistent-name question, see the PR).

Since 0a216d692 tangent and curvature extensions are SMLib's G1 and G2 extension of the surface
(smlib_extend_sheet, CreateExtendedSurface), and the face stays one face on it, as
surface_extend's docs say; extend_a_cylinder_strip_every_way still counted truck's separate
run-off face (2). It counts 1.
The test still fails after this, on the curvature run-off's area (see the PR): SMLib's G2
extension of the quarter cylinder by 5 gives 413.882 (a section 4.986 long), where the test
works out the parabola's 418.182.

cut_keeps_posts_joined_while_apart_in_one_body expected the reply's `bodies` as
["Case", "Case (1)"]. That list is the state's order, which is SMLib's lump order (the -x half
first); the names follow the pieces' faces (lineage::order_lumps, 08cf526fe): the piece whose
least face name sorts first keeps "Case". That is the +x half, whose least is `F1:+x`, before the
-x half's least, its piece of `F1:+y`. The test now checks the names as a set, that the +x half
(from x = 1) is "Case" and the -x half (from x = -30) "Case (1)", and each half's volume as
before.

Since 09c979a4b a circle is one closed arc, so an extruded circle's wall, a hole's wall and a
cylinder's side are one face each, closed along a seam. Tests that counted truck's two halves:
- certified_annulus_side_rows_follow_radius_edits_and_clone and
certified_side_transfer_preserves_geometry_and_unsupported_taper_refuses_atomically: the
painted outer wall is 1 face (every vertex of it still at the painted radius), not 2;
- offset_surface_of_a_cylinder_and_a_box_top: the offset sleeve is 1 face (its area 2π·12·20
unchanged);
- press_pull_then_curved_face_offsets_it: a click on the hole's wall offsets its 1 face;
- pi_case_faces_per_step_at_both_heights: each standoff (a ring, Ø6 round a Ø2.5 hole) adds 4
faces, not 6: its outer and inner wall, its top, the floor inside its hole. So 23 after the
first and 35 after the pattern of four; the port openings (3 × 4), the end cut-out (4) and the
five vents (5 × 4) are planar and add what they did: 47, 51, 55, 71.
- the_round_sides_of_a_thin_ring_are_named_by_the_circle_they_run_beside: a thin ring 2 thick
about the R10 circle has two walls, `F2:wall:c1:left` (radius 9: the counter-clockwise
circle's left is inside) and `F2:wall:c1:right` (radius 11), with no numbers; each name is
found again by a point on its own wall.

box_and_fillet_have_stable_wire_records compared the encoding of a box and a filleted box
with records truck built (2f4d6acac). Since f11c0c571 an operation's result is the record
SMLib gives, which numbers the box's faces in its own order and the fillet's edges by its
history, so the golden differed in face order, face sources and edge history, not in the
encoding. Rewritten with NATIVE_BREP_BLESS=1 and checked against the geometry: the box 6
planes, 12 edges, 8 vertices, each face source's plane its face's; the filleted box 7 faces,
15 edges, 10 vertices (one edge replaced by a face: +1, +3, +2), the round a cylinder of radius
2 along x on the axis (y, z) = (2, 8), 2 from y = 0 and z = 10.

Since 09c979a4b a full circle in a profile is one arc of a whole turn, so what is built from
it is one closed edge and one wall closed along its seam. Five kernel tests still expected
truck's halves:
- a_small_hole_in_a_large_spline_face_cuts_cleanly: the Ø1 hole adds one face (its wall),
not two; the removed volume (π · 0.25 · 40) is unchanged.
- fit_loop (two mesh_convert tests): a fitted circle is Loop2::circle, one segment.
- tight_bend_counts: a Ø10 tube swept up 20, round a quarter turn of radius 5, along 20. The
circle starts at (5, 0), which runs up to (5, 0, 20) on the bend's axis, where the turn
leaves it: the bend face has no seam and both straights' seams end there. By the ladder's
rule (each whole curve once, each seam): 5 faces (2 caps, one per path segment), 6 edges
(4 circles, 2 seams), 3 vertices (the seams' ends: (5,0,0), (5,0,20), (25,0,20)), the
record's own counts.
- extruded_circles_go_as_cylinders: the record holds the wall as the cylinder it is (one
face of three), no longer a rational spline; it still goes into SMLib as its cylinder.

A folded edge's Hermite pcurve on a bend's form breaks where the edge's angle crosses a
quarter. At the 120 degree corner with flanges at 60 and 90 degrees under a tear, an edge
starts 3.25e-12 of its parameter short of a quarter: the crossing was kept as a break
(breaks within 1e-12 of the parameter merged), the pieces halved to 1.6e-12, and SMLib,
given knots 1.6e-12 apart, handed the pcurve back with 15 equal knots at degree 7 ("SMLib
export: pcurve: loop 0 use 1: given pcurve: portable B-rep: knot multiplicity"). A crossing
whose point on the edge lies within the pcurve's lift accuracy (FOLD_TOL of the edge's size)
of the previous break is that break; the end is never merged into the start.

Two expectations encoded truck-era output:
- a_flange_bent_inside_keeps_the_base_sketchs_arcs_in_the_flat_pattern_and_the_dxf: the
DXF has 7 LINEs, 4 ARCs, 11 shapes (was 9, 4, 13). The flat outline is SMLib's exact 2D
union of the plate, the bend zone and the flange panel; a zone's side and its panel's side
meet in line, and a region's boundary has no vertex in the middle of a straight run, so
each flange side is one line: 6 outline lines (plate top, left, right; flange sides and
end) and the bend's centre line. The same reason as 5d25684a1 gave for
a_base_trimmed_for_a_flange_keeps_its_arcs (12 to 10 edges). Areas, the bend length and
the volumes are checked as before and hold.
- hole_beside_two_adjacent_edge_flanges_cuts_and_bends_stay_guarded: the folded volume was
14057.2 +- 0.1, a faceted measure; since 32ae0cd9c the measure is SMLib's exact integral,
14057.3837123. Exactly, a folded sheet holds its flat area A times t, less each bend's flat
strip L·t·(R + K·t)·π/2, plus its sector L·t·(R + t/2)·π/2: t·A + t²·(½ − K)·(π/2)·L. With
t = R = 2.5, K = 0.44, A = 5597.0353454 (the flat pattern) and L = 75 + 35, that is
13992.5883635 + 64.7953485 = 14057.3837120, within 2e-11 relative of the measure. The
test now checks that identity to 1e-9.

A face's sheet name is the name 80% of its mesh triangles' centres agree on. SMLib's
mesher fans a 1 mm rim (30 mm tall) into four triangles about its middle; two of their
centres lie 1/6 mm from the panel's top or bottom face, inside the 0.2·t tolerance, and
took that face's name, so the rim got no name (rim.side0/side1/ext0/ext1 of the tray's
flanges: 6 faces unnamed). A flat face's name now needs its plane to face along the
triangle's normal (within 1e-3); otherwise the point is a rim's, a bend's or an ext rim's.
No face changes name: these faces had none.
sheet::face_names_tests::a_trays_faces_have_readable_sheet_names_that_follow_its_size now
passes its naming checks and fails later, on the point named_face_point gives for a rim
(the roomiest triangle's incentre, 0.497 mm from the rim's edge, not 0.5).

A hole drawn on a flange's face and cut through ("direction": "negative") was refused as
"below the supported 0.000001 mm extrusion resolution": the flange panel's frame, turned
up by the cosine and sine of 90 degrees, puts the panel's origin at -1.9999999999999998
along the sketch normal, so the cut ends 2.2e-16 mm short of the sheet's far face and
reads as a layer 2.2e-16 thick. A depth within four units in the last place of the
numbers it is worked out from (the frame origins, the tool's span and the thickness) now
lands on the face. A real thin layer stays: a 1e-8 mm layer of a sheet 1e5 mm from the
origin (bound 9e-11 there) is still refused

Since 09c979a4b a circle in a profile is one closed arc (Loop2::circle). The sheet's
faces passed it to the sew as one arc edge from a point back to itself, which the sew
refuses ("sew: a degenerate edge"): a sewn edge runs between two vertices, and an arc
edge is the circle through its ends and middle. A disc's flange failed (first with the
4-face minimum, then with the degenerate edge). Each closed curve of a cell is now split
into its two exact halves (Seg2::split_half) where the cell's edges are prepared, as a
hole's wall already came out: a disc is two caps and two half walls.
sheet::tests::tiny_cut_inside_exact_circle_survives_unfold_refold_and_dxf now builds the
disc flange and fails later, on SMLib's extrude of the 50 nm tool (an SMLib tolerance
defect, reported separately).

The case expected "drill 6.75 mm for M8", the major diameter less the pitch.
Since 05f1c6b9a (Tapped holes: the tap maker's drill for every form) a tabulated
size names the tap maker's drill, 6.8 mm for M8 x 1.25 (Yamawa YEU23 p.704), as
case 2115 already grades and engine thread_tests.rs asserts; major less pitch
is for a size no table lists. The refusal itself and its reason are unchanged.
The case passes and leaves threads/KNOWN_FAILING.

The zero-area triangle is dropped (previous commit): the box converts with six
faces and V = 1000 mm^3, as the case expects.

A triangle whose corners lie on one line (or weld into one another) adds no
surface, so welding now drops it, with any corner only it used, instead of
refusing the whole mesh as having a degenerate triangle. The closed and
consistently oriented check that follows still refuses a mesh that needed it to
close, and a mesh of nothing but such triangles is refused by name. Dropping its
unused corners keeps a dropped triangle from widening the part's extent, which
the prism search reads from every position.
Regression test a_zero_area_triangle_is_dropped: the 20 x 10 x 5 box with the
case's extra triangle (0,0,0) (10,0,0) (20,0,0) converts to six faces and
V = 1000 mm^3.

fixed_seeds_run_clean expected the join of a box touching the first only along
an edge to be refused with "zero-thickness edge contact". Since 94ee28d5c (doc:
a join keeps solids that only touch as separate bodies) such a join succeeds and
keeps the new box a body of its own with an along_edge notice, which
join_touching_along_an_edge_keeps_a_separate_body asserts in engine tests.rs.
The seed now expects that: the notice, two bodies, each valid, and the volumes
unmoved, 25 x 15 x 10 + 17.5 x 17.5 x 20 = 3750 + 6125 mm^3.

SMLib's thickening of the test sheet makes a top face of 72 x 78 control points,
which the 4096-point cap refused (TooLarge) before the solver saw it. The band
cap (2^21 entries, 16 MB) is what bounds the system's memory and its
factorisation (at most n min(n, bw)^2 work); the 72 x 78 bicubic net needs
5320 unknowns 213 apart, 1.14 M entries, well within it. The point cap now
bounds only the per-step energy sweep and the net's copies: 2^14 points, above
the band's own limit for square bicubic nets (about 90 x 90), so a face is
refused for the system it needs rather than its size. The hostile-input test
asks for 129 x 129 and checks the refusal is TooLarge.
a_body_face_is_faired_with_its_edges_untouched_and_its_history_kept passes.

The README demo's Raspberry Pi case stands four standoffs on its floor: Extrude2's ring of
radius 3 round a 1.25 hole, patterned by RectangularPattern1. Each is its outer wall, its inner
wall, its top and the floor inside it: four faces. The recorded counts were truck's, which made
each cylindrical wall two halves (six faces a standoff): 25 after feature 6, 43 after the
pattern, and 8 more than now at every step after it. On SMLib each wall is one face closed on
its seam, and the counts are 23, 35, 35, 47, 47, 51, 51, 55, 71 from feature 6 on (the feature
names show it: F6:side:c1, F6:side:c2, F6:top and the floor piece bounded by F6:side:c2 per
standoff). The outer sides stay one face each, and (b) and (c) still agree step by step.

A face on a B-spline surface closed around u (first and last control columns the same) may lie
across the surface's start without winding round it: the strip on a radius-3000 rational
cylinder whose seam is 0.001 rad into the strip. A kernel's trims run inside the surface's
knots, so its pcurve came back clamped at the start, 2.28 mm off its edge, and the strip was not
imported.
Before seams are added, such a surface is started anew in the middle of the stretch of u the
face leaves free (each loop followed round, unwrapped across the start; a face winding round is
the seams' to handle): the new start inserted to full multiplicity and the piece after it put
before the piece before it, a period on. The same points, a period apart in parameter before
the new start: exact. The face then lies inside the knots.

Two tests counted the old 2D boolean's edges, which kept a vertex wherever an operand's corner
or edge end lay on another's edge. SMLib's planar boolean leaves no vertex that is no corner:
edges on one line within the tolerance are one edge. The results are the same regions with
fewer, whole edges, and each test's point stands (no edge shorter than the tolerance, no sliver):
- a quadrilateral cut away from below a square whose bottom edge it lies on within 1e-8 (tilted
1e-9 rad) leaves the square's four 10 mm edges (its corner at x = 4 is within 1e-8 of that
edge's line), and its union runs along y = 0 as one 14 mm edge (the quadrilateral's bottom
edge is within 1e-8 of y = 0 all along): [4, 5, 5, 10, 10, 14];
- the bent plate and the strip under it: their ends on the line x = 150 are one edge from
y = 47 to 80, six edges for every turn and offset tried, the shortest 3.

Reading a planar sheet's faces back as regions, each hole went to the smallest outline whose
Loop2::contains held its middle: even-odd against the outline's polyline within 1e-3 mm. A
5e-5 mm square cut 1.7e-4 mm inside a radius-10 circle lies outside the polyline's chords there,
so no outline held it and the cut failed ("face 0 has a hole outside its material"). An

94bd8719a (#3730) turned a BREP_WITH_VOIDS void inside out when it enclosed volume of the
outer shell's sign: SOLIDWORKS writes .F. over a void shell already facing into its cavity,
SolidCraft .T. That lived in the truck reader; the schema-4 reader (crates/step) that replaced
it took the flag alone, and the block with a 20 x 6 x 5 cavity read as 15600 (the cavity added)

The reader now takes each void's sign from the faces themselves before it orders the record:

A whole circle is now one closed rational curve (Loop2::circle is one segment), whose first
control point is repeated as its last: the mean of its nine control points sat r/9 towards the

Under the blend-overflow decision (237f0ae74) a convex round running over a face's far
edge (a cliff) is built and cut from the part, so the truck-era fixtures of the reduce
and taper fits (a 2 mm fin, a plate narrowing to 2 mm, a wedge, a 10 mm cube's edge at
R20) no longer refuse their radius and the fits have nothing to react to. Each test now
uses a case SMLib still refuses, and checks the cliff case builds:
- engine fillet_fit_reduce_keeps_the_radius_where_it_fits: a 14 x 6 x 10 post on a
40 x 30 x 20 block, its four verticals at 3.5 (two rounds would cross on its 6 mm ends)
reduced to 3 on 4 of 5 edges, the block's corner kept at 3.5: 24840 - (4 - pi) 90 -
(1 - pi/4) 3.5^2 20. New fillet_fit_reduce_keeps_a_round_over_a_cliff: the fin's R4
builds, nothing reduced, at the kernel's fillet_max_each answer.
- engine fillet_fit_taper_follows_the_room_along_the_edge, spline_fillet_takes_over_a_taper,
kernel taper_follows_the_room_along_the_edge, ui-egui fillet_spline_handle_tests: the
narrowing plate stands against a wall behind its slanted side (z -15 to 30), so its top
and bottom end in concave edges: R3 is refused and tapers 3 -> 1.8 as before. Without
the wall, R3 is cut over the 2 mm top's far edge and kept constant: at x the section
loses (1 - pi/4) 9, or 3 w - (F(3) - F(3 - w)) where the top is w < 3 wide, 6522.7745566.
- The wedge closing to a point: on its own R16 is cut over its cliffs (the section
integral, 4195.578821, SMLib within 4e-8) and kept; its room's taper is checked as a
spline fillet. Against a wall (new fillet_fit_taper_closes_to_a_point) the taper must
close to 0, which SMLib fails today (status 1001).

The owner's blend-overflow decision (2026-10-25, 237f0ae74): a convex round or chamfer
whose rail runs off its face across a cliff (an opening's rim, a hole, the part's
outline) is built on the faces continued and what it removes is subtracted, so it never
bridges an opening; a round may use up a face; a chamfer of a face's full width stays
refused. These tests still expected truck's refusals. Each now expects the decision's
body, with its answer from the geometry:
- issue_1080 chamfer_into_a_pocket_is_cut_by_it (was ..._is_refused_with_the_size_that_fits):
chamfer 6 into the pocket 4 mm in removes 360 - 20 (its triangle less the part over
the pocket): 14660; 6 along the top and 2 down, 120 - 20/3; 2 and 6, 120.
- issue_1080 fillet_into_a_pocket_is_cut_by_it_and_one_that_fits_builds: R5 removes
(1 - pi/4) 25 along 20 less 10 (5 - (sqrt(24)/2 + 12.5 asin(1/5))): 14893.0344442.
- issue_1080 chamfers_crossing_each_other_are_refused: still refused (they cross);
chamfer_max and fillet_max find 2 mm.
- issue_1080 rounds_on_both_sides_of_a_wall_build_as_one_fillet: R7 alone opens a slit
where its arc passes the inside corner: V0 - (104 (1 - pi/4) 49 - 100 a), a = the square
[25, 30] x [35, 40] outside the circle about (25, 35), 5 (5 - sqrt 24) - (F(5) - F(sqrt 24)):
38458.8958265. Both at R7: the arcs about (25, 35) and (23, 33) cross only outside both
quarter arcs and the inner round's material holds the slit, so V0 - 4 (1 - pi/4) 49 =
39509.9380404 (was expected refused).
- issue_324 a_round_into_a_hole_is_cut_by_it (was the_radius_offered_beside_a_hole_fits):
R4 over the r3 hole: 8000 - 90 pi - (640 (1 - pi/4) - the round's height over the
hole's width, integrated with y = 17.5 - s^2): 7580.2873154.
- issue_851 arc_top_blend_uses_up_the_wall_and_refuses_a_collapsed_one: a round of the
wall's full height uses the wall up (one face for the wall, the removal integrated as for
the other sizes); the full-height chamfer stays refused.
- kernel tests: fillet_max_finds_the_largest_radius_that_works keeps the post (3.5 -> 3)
and the no-edge case; its disc and notch cases move to
rounds_past_the_bottom_of_a_wall_are_cut_from_the_part: the 2 mm disc's R2.5 turned
section, pi (338 - integral of (169 - rho^2) dz), rho = 10.5 + 2.5 cos(theta) (the same
formula gives SMLib's R2 994.15188 exactly), 957.6922389; the notched block's outline
R7, 11925 - (1 - pi/4) r^2 (140 - 8 c), c = r (10 - 3 pi) / (3 (4 - pi)) (SMLib's R7 within
5e-8), and R8 less its part over the notch, integral of 2 (5 g - g^2/2), g = 8 - sqrt(64 - t^2).
- kernel tests: chamfer_wider_than_sloped_basin_rim_is_cut_and_a_full_width_one_refused:
past the 1 mm and 0.5 mm rims the chamfer runs over the slab's front edge and is cut:
the clipped triangle's area (30 + z centroid), its length 60 - h between the sloped end
walls (the same formula gives chamfer_sloped_basin_rim's fitting chamfer to 1e-12);
a chamfer as wide as the rim is refused.
- blend_corner sloped_rim_fillets_stay_inside_the_material, equal_slope_rim_loops_stay_
inside_the_material: R4 and chamfer 2 over the thin rim build, every vertex inside the slab.
- engine blend_fit chamfer_through_the_openings_is_cut_by_them: the report's 9 mm chamfer
is cut by the openings, 3350 (the rig's fillets/1080 case).

Since bcbb99005 a blend larger than its faces is SMLib's refusal (KernelError::TooLarge,
"the fillet is larger than the faces beside its edges allow"); truck's room check, whose
words these tests still matched, went with blend_fit. The refusals themselves stand:
- fillet_consuming_a_side_face_makes_a_full_round: R3.001 and R3.5 on the 14 x 6 x 10
box's four vertical edges, past the full round, are refused as too large (no longer
"larger than the neighbouring faces"); the body unchanged is its own volume before
(SMLib's measure of the box is 839.9999999999998, not 840 bit for bit).
- a_chamfer_that_would_grow_the_part_on_a_convex_edge_is_refused: refused as too large;
the word "convex" was the old check's.

When the kernel's room pre-check went (bcbb99005), a fillet or chamfer refused as
too large stopped saying what would fit: only SMLib's NO_ROOM words were left. The
rig expects the refusal to name it (fillets/4782-fillet-two-end-verticals-past-a-full-round:
"the largest radius that fits is 7.5 mm", fillet_max for the exact fit).
A constant fillet with the exact fit, and an equal-distance chamfer, refused as too
large now add "; the largest radius (distance) that fits is X mm", found by the same
bisection fillet_max runs (up to 16 blends, three significant digits), now shared with
a new kernel::chamfer_max. Where the search itself fails (a candidate failing for
another reason), the refusal is left as it was. The reduce and taper fits and the
kernel's own searches call the kernel blends directly and do not pay for it.
Tests: the 14 x 6 x 10 post's R3.5 names 3 mm; a 4 mm rib's crossing chamfers and
rounds at 3 name 2 mm.

sweeps_along_paths expected one wall for the circle swept through 41 points of
a smooth curve: a point path is the polyline its points make, swept line by
line and mitred at each point since 43e8b0349 (sweep_path's own test expects
40 + 2 faces since d9274aaf1), so the circle's one segment has a wall along
each of the 40 lines.
The holed square along the L-shaped path expected two faces per segment. The
corner turns the profile about Y, so each line at a constant y (the outer
loop's segments 0 and 2, the hole's 1 and 3) sweeps the plane y = c it lies in
along both legs, and the two walls meet edge to edge on the mitre in that one
plane: one L-shaped planar face. The lines at a constant x sweep two planes,
two faces. check_sweep takes the count per segment.

sweep_origins read a sweep_path tool's faces by the truck face order (walls in
profile order, then the start and end caps), and fell back to swept_origins,
which names a face without an edge in the profile's plane an end cap. SMLib's
sweep along lines and arcs is made piece by piece and mitred at each corner
(tangency-labs/smlib#43), so most walls start further along the path: 39 of a
44-face sweep came out as end caps (105 of 110 before the previous commit). The
sweep records each face's origin as it builds it (Body::history), and
sweep_origins now returns those, finding by geometry only a face the tool names
no origin for. swept_origins says what it holds for.

A sweep along a path with corners sweeps each run past its corners and cuts it
back to the plane halving the corner. The lead past the corner was the
profile's reach times tan(turn / 2), enough only for a profile square to the
path. A point standing s ahead of the path and w from it needs
w tan(turn / 2) - s past a corner (w tan(turn / 2) + s before one): a profile
at a slant to its path reaches across the mitre by its slant as well, and a run
carried short of it leaves a notch with a piece of the run's section in it.
The section keeps both distances along a run and through each corner (it
turns with the path; a twist keeps them, an end scale grows them by at most
its largest scale), so the lead is taken from the profile's points at the
start, for the plain and the controlled sweep. A profile square to the path
(s = 0) leads exactly as before.
The walls' history seeds sat at the middle section of each run, which for a
slanted profile on a run shorter than its slant lies past the mitres, on the
next run's wall: half the walls came out generated. Each piece's seed now sits
half way along the stretch its own point keeps between the mitres, carried
there exactly along lines and arcs (as SMLib's sweep turning with the path
carries the profile), at the station there in the controlled sweep.
A flat 4 mm square swept along 21 points of a rising sine (provenance test):
110 faces, 66 of them notch faces, and walls left unnamed; now 44 (two caps, the two
walls in the path's plane, a wall of each slanted side along each line), volume
16 cos(slant) L to 1e-6 (new test a_slanted_profile_meets_itself_at_every_mitre).
The square round a closed 122-line polyline (issue_2005
closed_polyline_sweep_shares_its_starting_section): the first section leaned
by half a chord's turn left a 6.2 mm^2 piece of it at the closing mitre, named
the start cap; now 246 faces, every one a wall.

legacy_internal_capture_refuses_an_uncaptured_source_in_another_component
picked the top Offset Face raised as a face with neither a construction
certificate nor an exact history name (#494), to reach the legacy path
that refuses a profile across components while the source occurrence's
move is uncaptured. Offset Face has SMLib's history since 0f3d6f177 (shell,
offset faces and thicken through SMLib), so that top is now named exactly
(F3:+z#[F3:-x], verified) and capture_face_anchor gives it a lineage
anchor; the legacy path is not taken, and the capture is right to
succeed: an anchored attachment captures its path's pending positions
when it is made (capture_positions).
The test, renamed to what it now checks
(internal_capture_in_another_component_anchors_an_offset_face_by_its_history_name),
asserts the face still has no construction certificate, the capture is a
Lineage anchor on the occurrence's path, and capturing changes neither the
document nor the pending moves.

The test cut three regions from a plate that keeps its meshes and
expected the memo to hold one mesh afterwards: the old kernel's booleans
meshed their operands. On SMLib (ops::boolean -> smlib_boolean, since
42c41464a) a boolean reads the exact record and a tool apart from the
body is found from the exact boxes, so no boolean meshes anything and the
memo is empty after them. The test now asserts that, then that meshing
the kept body twice at one tolerance makes one memo entry, bit-equal to a
fresh mesh, which is the reuse the memo is for.

Split Face records its lines on the body (split_lines): heal and the
certified-planar regularizer keep the faces apart along them, and they
make the body regularization-protected. On SMLib the boolean, the n-way
union and Shell carried the protection over but dropped the lines, so a
body with an authored split lost its record after a Union with partial
contact (issue #674/#782's case), and a shelled one after Shell. Each
result now keeps its operands' lines, each line once
(Body::inherit_split_lines), as the old kernel's coplanar join did.
regularization_protection_tests: SMLib's shell makes no section strips,
so the painted cup no longer has more faces than the ordinary one. The
ordinary cup is the box's five kept faces, their five linings and the
rim: 11. A paint over a whole face authors no boundary inside it, so the
painted cup has the same 11 faces; the split side's line stays an edge on
the wall and its lining: 13. The test now asserts those counts exactly
(it asserted more than 11 for both, the old strip route's witness) and
that the split lines survive.

The test helper side_by_side copied the second body's regions by hand,
dropping its voids and keeping its infinite region (region 0) as if it
were a bounded one. Its closed shell was then the outer shell of two
regions, which the portable record refuses ("a closed shell bounds two
regions and encloses one"). The helper now joins the two records with
geom's brep::part::compound, which puts each body's outer shells in the
one infinite region and keeps its bounded regions; the face sources are
still found by plane afterwards, so nothing the test checks changes.

Body::parts (and so Body::lumps) mapped each piece's faces through the
body's face-source table with a silent `get`, so a table shorter or longer
than the body's faces gave its pieces sources of other faces, or none. The
table is by face position: one whose length is not the body's face count
belongs to another body. The pieces are now refused with "lumps: face
source table does not match the body", as before the SMLib port (the check
went with the old lumps_with_clearance in 66e31bede).

Which input plane each result face lies on was found by scanning every input plane whose
normal x was within the resolution's angle: quadratic on axis-aligned parts (two thirds of the
faces have normal x = 0), so it was capped at 16 384 faces a body and 2 M comparisons, and the
join of the 20 level-2 sponges of a level-3 Menger sponge (7 326 faces) was refused past the
comparison budget.
The planes are now indexed by their unit normal, in cells twice the bound on two matching
normals' difference (asin(angular) < 2 angular), and in each cell by their offset from a common
centre, searched in the window linear + |a.o - c| |n_b - n_a| that
d_b - d_a = (b.o - a.o) . n_b + (a.o - c) . (n_b - n_a) gives, plus rounding slack. The index
offers a superset; same_support still decides each match, and candidates are taken in the same
order as before, so every answer is unchanged. A plane with a normal not of unit length is
offered to every query. Both caps are removed: results are bounded by inputs capped where they
entered. The descriptor-size budgets on kept roles are unchanged.
Rig, --known-failing, results compared case by case with develop's: booleans (129) and shell
(28) identical except booleans/5126-join-menger-sponge-level-3, which now passes in 38.9 s on
aarch64 and leaves KNOWN_FAILING.

outer_area, which decides whether SMLib's normal is the record's for each
face, copied every edge of the body into a record for each face before
computing the pcurves of that face's outer loop: O(faces x edges) curve
clones, on every operand and every boolean result. pcurves now takes an
edge lookup instead of a slice of edge records, so outer_area reads the
loop's edges where they are. The pcurve routine gets the same curve,
interval, tolerance and trims as before, so every area, face turn, record
and numbering is bit for bit what it was.
On the level-4 Menger sponge with 3 tools, body_from_smlib_ordered goes
from 92.6 s to 1.3 s of self time.

explode.show put the view's placements in the uncaptured moves, so occurrence.properties reported
the exploded placement and Capture Position (and reparenting, moving bodies between components,
copying or pasting in place, URDF export) wrote the view's offsets into the design. The session
now records which uncaptured moves are the view's (Session::exploded); what reports the design's
placements or works a new placement out from them uses the design's own moves
(uncaptured_moves, design_document), while the viewport and picks still show the view.
New case cov-explode-show-keeps-the-placements: the arm's properties are the same before, while
and after the view is shown, and Capture Position keeps nothing. The two explode cases that read
occurrence.properties while exploded now expect the design's placement, centre (20, 0, 5), as the
command says ("shown only; the design keeps its placements").

The curves were held on a 1-2-5 ladder from the world origin, so count 3 on a 40 x 30 face gave 3
one way and 2 the other. They now follow the command's contract: the held parameter at
lo + k (hi - lo) / (count + 1), k = 1…count, over the face's extent. Faces of the body on the same
surface record are spaced together over their combined extent, so a face a boss splits still
shows the same lines straight across the split.
New case cov-isocurve-40-by-30-face-count-3: x = 10, 20, 30 and y = 7.5, 15, 22.5, to 1e-9 mm.

Both walked the picked curve's display polyline: a point a third along an R10 sketch arc was
0.87 µm off (8.6603, 5). They now evaluate the path's exact curves by arc length: lines and arcs
in closed form, a free-form span at the parameter its arc-length integral reaches (body edges by
their record curves, 3D sketch curves by their arc, spline, line or linked exact curves; only a
curve that exists as points alone, an intersection edge or a projected curve, runs along them).
The arc's point is now within 1e-12 mm of (10 cos 30°, 5, 0).
A t outside 0…1 was clamped silently, which the contract (`t: expr, 0…1 along it`) does not
say: it is refused ("t is 1.5: a point along a path is 0 (its start) to 1 (its end) of the way
along it"). The construction cases grade the arc and line to 1e-9 mm, past-the-end is refused,
and a new case takes the middle of a symmetric cubic spline, (20, 7.5).

A face of degree 1 in one direction (an extruded spline) was refused with "a fairness term does
not fit the net's degrees": the thin-plate energy's S_vv asks for second derivatives a linear
direction does not have. On every span that term is exactly zero, so it is dropped; the energy is
the bending along the curve and the twist. A face whose held layers are its whole net (a
single-span cubic with its edges kept, an extruded curve's two rows) has no interior control
point: it is left exactly as it is, its energy reported unchanged, 0 steps.
cov-fair-single-span-face-has-nothing-free-to-move passes and leaves KNOWN_FAILING.

The portable record's 4,000,000-item budget refused a real result: the join of a level-4
Menger sponge's level-3 sponges ended with "SMLib export: the mapped B-rep does not validate:
portable B-rep: item budget". The budget guards records from outside the kernel, and a body
the kernel built in memory from inputs already bounded where they came in isn't hostile.
Brep::validate keeps the budget for records read from outside: native design caches
(decode_native_body, behind its own 256 MiB, 1M-per-array and 20M-value caps) and STEP import.
The new Brep::validate_built runs every other check, without the cap, on what the kernel
builds: SMLib's export of an operation's result, a body's record (Body::from_record, after
the decoder has checked a file's), a part of a validated record, the record handed back to
SMLib, and the validity check. Its checks are linear in a record already in memory.
SMLib's export bounded its counts by the same budget; a count is now bounded by SMLib's own
longest array (flat::MAX_LEN, checked on entry), which keeps every offset worked out from
the counts from overflowing, and the redundant topology-length cap goes.

Where a round meets a plane it is only tangent to it: its curvature jumps by 1/r there, so no
corner patch can be G2 to both at that point. The cases graded the whole seam and could not pass.
They now bound the curvature jump at stations clear of each seam's turn, within reach of the
corner, scaled by r (ladder 07/019's bound at r5): r1 within 2.2 mm, 0.24 mm clear, 0.005 per mm;
r5 within 11 mm, 1.2 mm clear, 0.001 per mm. Develop's corner gives 0.00135 and 0.00027 per mm
(the jump at the vertex is 1.017 and 0.2035, the round's own 1/r), so both leave KNOWN_FAILING.

When a − b or b − a cannot be made (a kernel error, or a body that encloses no volume), the
region's volume and centre are null, measured_by is "not measured" and not_measured gives the
cut's error; its deviation, area, faces and box are still given, the side's total is null and
the verdict says the volume is not measured. The integrated-along-lines estimate is no longer
reported as a volume.

inspect.compare integrated a region's volume along sampling lines: the
40 x 30 x 5 slab between a box and one 5 mm taller came out at 5976.49 mm3
against 6000. The regions are still found from the two surfaces; each one's
volume, centre and box now come from the pieces of the exact cut a - b (or
b - a) that lie there, measured as inspect.measure measures a body
(measured_by: boolean). Where a cut cannot be made the region keeps the line
integral, marked measured_by: lines, with a warning. The rig case
cov-compare-taller-box passes.

The groove's section was cut square a fixed margin past the crest. The crest cone changes 1 in 32
along the axis across the section's own width, so for NPT (margin 0.015 mm against a 0.028 mm
rise) the section's deeper corner stopped under the cone and each tooth kept a sliver of its
flank: 0.94 mm3 too much on a 1/2-14 NPT. The section's edge now follows the cone at the same

A plan job (scripts/ci/kernel_rig_plan.py, with its self-test) maps a pull request's changed files
to the areas: tests/kernel-cases/<area>/PATHS for each area, tests/kernel-cases/PATHS-ALL for the
shared core, the ladder whenever any area runs. Areas come from the folders, so a new one needs no
workflow edit. Pushes, merge groups, the release gate and runs by hand run every area. The
kernel-rig check counts a skipped build or shard as passed only when the plan selected none.

The gate passes no secrets to release.yml, so the macOS and Windows signing steps skip as
they do on a fork (no signing secret, no SignPath quota), and the new packages_only input
skips the release job (checksums, update signing, publishing). The call still grants
contents: write, which GitHub checks for the skipped job before the run.

kernel-rig.yml builds solidcraft-cli once (release, SMLib prebuilt; sccache on a sticky disk

SMLib's parallel projection (CreateParallelProjectionCurves) gives every curve where the
projecting lines cross the face: a line projected down onto a ball came back as its top and its
bottom, each split at the pole, and the link's first wire was half the bottom. A projection onto
a surface is where those lines first hit it (owner's decision, as mainstream CAD does): a curve
is now kept only when the first hit on the body's mesh along the line through its middle is the
curve itself (within 4 chord tolerances), and the pieces that meet end to end are joined in
whatever order and direction they come, a piece run the other way exactly (its knots and
control points reversed; a line's, circle's or ellipse's parameter mirrored). The ball's top
is then one wire from x = -10 to 10.
three_d_sketch_curves now expects that exact curve: one wire, its ends at (±10, 0, √300), every
point of its exact curves on the sphere of radius 20 in y = 0 over the top, to the projection's
own tolerance (a millionth of the body's size), and sweeps_and_pipes_follow_3d_sketch_curves
pipes along the whole joined top. Both pass on the pinned SMLib (90aabff): the pieces lie 9.1e-6
off the sphere against a 4e-5 tolerance and meet at the pole within 4.7e-8 rad, since the fork's
8d95600 keeps the pole's exact tangent in StepBackFromSingularity.

path_points took any wire with three or more fit points as a fitted spline, and a 3D arc keeps
its start, through and end points as its fit: the pipe along a quarter arc of radius 20 ran
along the cubic through those three points and came out 388.06 mm³, not π·2²·10π = 394.78.
A wire with its exact arc (Wire::arc) now goes to the kernel as that circle, from its start
counter-clockwise about its normal through its sweep (kernel::curve_path of the record circle).

Design defaults gains a Surfaces section with one setting,
surface_extrude_symmetric_per_side (off by default). When it is on, new
symmetric surface extrudes go their distance each way, as they did
before they matched solid extrudes. The app hands it to the session
before every command and each frame, and it stays with the user across
tabs and new designs, like the metric tap drill rule.
The Surface Extrude dialog now sends a feature's stored convention only
when the feature is already symmetric, so a one-sided one switched to
Symmetric takes the new reading, as in the solid Extrude dialog.

A symmetric surface.extrude given no convention now splits its distance
evenly around the start plane (10 mm: 5 mm each side), the way
solid.extrude reads it, instead of going the distance each way. Both
commands take their default from one function, which a session setting
(surface_extrude_symmetric_per_side) can turn back to the per-side
reading for surface extrudes. timeline.edit and timeline.redefine give a
one-sided surface extrude made symmetric the same default.
Saved designs are unchanged: every surface extrude saved its convention
(legacy_per_side), and one saved before the marker existed reads per side
as it always did. The help of both commands says how the distance is
read. The 3830 kernel case, recorded with the per-side reading, now says
so explicitly.

The barrel's arc has its centre across the axis, so its side is the inner (lemon) zone of a

cylinders extended as themselves, a cone's apex offset as a sphere, a wall
that would turn a face inside out refused, neighbours extended to reach a
face moved past the body's size, an open edge's trim point on a closed curve.
- Draft (#27, #53): a cylinder along the pull drafts to a cone, a cone about the
pull to the cone its turned generators make.
- Sweeps (#14, #31, #36, #37, #40, #43, #44): a whole turn of a holed profile
leaves the void, a curve near a circle swept as itself (text outlines' Béziers
pass the check), an arc centred across the axis revolves to an exact B-spline
surface of revolution, a minor circle on the axis and a horn torus, line and
arc paths swept exactly piece by piece.
- Surfaces (#18, #19, #20, #21): a B-spline starter in Bezier form, extend by the
distance across the surface and as the same cone or cylinder, untrim in place.
- Intersections (#35, #46, #52): a curve into a pole keeps its tangent, a periodic
value just past the top wraps a period down, a curve from a singular point
starts inside.
- Checks, history, measure (#15, #16, #33, #41, #42, #54): a face whose edges
moved is Modified, SMLib's warnings are no failed test, sheet faces count in
the area, internal poles sought in the knot's row, a collapsed seam not
classified, a small loop oriented on the surface's scale.

SMLib now sweeps a curve within the tolerance of a circle as itself, not as that
circle's cylinder (tangency-labs/smlib#31, 3cfbbdd), so the offset curves' pieces
meet with one curvature at every wall join of the ring (the largest curvature
jump 4.2e-7): all 512 are smooth, where 400 were and the other 112 jumped by
0.9-3.6%. The comments that said the pieces meet only tangentially, or at small
real creases, go.

With SMLib integration-overnight + b78bd4a (the fixes of 2026-10-29), three
expectations that held a refusal now build, each checked against its exact answer:
- rig fillets/1207-fillet-box-end-edge-into-unblended-round (was ...-refused): the end
face's top edge of a cube rounded r3 along its top back edge, rounded r1 alone
(tangent chain off), builds. Its round runs on along y through the r3 round's end
until that surface drops below it at y = 17 + sqrt(5): V = 8000 - 20 (9 - 9 pi/4)
- 17 (1 - pi/4) - 0.218236 = 7957.505202 (the last term the section under the round,
integrated exactly); SMLib gives 7957.505245.
- blend_smlib smooth_edges_and_unfinished_tangent_chains_are_refused_saying_why: the
same cube builds, at that volume.
- modify_history_tests::smlib::draft_tilts_a_side_and_keeps_its_name: the rod's side,
a cylinder along the pull, drafts 5 deg to a frustum, radius 5 at the neutral plane
and 5 - 10 tan 5 deg at the top, at its exact volume.
tests/kernel-cases/fillets/KNOWN_FAILING drops 1557-fillet-vertical-corners-after-
bottom-rounds, which passes now; the other eight still fail, so the gate holds
(81 pass, 8 known failing, no regression).

Since an operation's result is its record (f11c0c571), a mirrored body is
SMLib's transform read back from SMLib's export, and two SMLib defects there
made it invalid: a mirrored cylinder came back inside out the wrong way
(SmCylinder::IsNurbSurfaceCylinder; its edges 10 to 30 mm off the surface),
and every edge's own tolerance was reset to the body's (SmBrep::Transform).
Both are fixed in SMLib (fix/mirrored-cylinder-from-nurbs e02e63e, c603293,
with e008e82 for a scaled body without vertices);
this test needs the SMLib pin moved past them.
A plate with a through hole and a box with two rounds meeting at a corner,
mirrored in x = 30 and read back from their records: SMLib finds both valid
and their volumes are the originals'.

notch_into_a_ring_chamfer_is_cut_exactly measured the notch as the ring's mesh volume before less
after (0.2906 against the integral's 0.28665) and oblique_cuts_through_a_chamfered_ring_are_exact
compared the two mirrored cuts the same way (3.3e-4 apart). The cut is right: the ring less the
cut ring is a piece of 0.2866521 mm³, the integral to 2e-6. A difference of two 1149 mm³ volumes
is not: the re-tessellated ring's mesh volume moves by 4e-3, and SMLib's mass properties (at
their finest, 1e-4 asked) by 1.5e-6 of the ring, 1.7e-3. Each cut is now measured as the piece it
took away (the ring before less the ring after, an SMLib boolean), to 1e-5 of the integral and
1e-6 between the two mirrored cuts.

SMLib keeps a whole cylinder one face and the arm's round end and the boss over it (one
cylinder) one face, named for the arm's end. Three naming tests relied on truck's pieces:
- a_cut_through_one_of_two_bosses_names_only_its_own_walls finds the boss's wall by a point
on it (the centroid of truck's half cylinder lies on nothing now) and checks it keeps its
name through the cut and the fillets;
- split_pieces_keep_their_numbers_across_evaluations keeps the torus (its sweep's walls are
whole now, their names stable) and adds a disc whose top a round groove splits into
F1:top#1 and #2;
- a_design_saved_before_pieces_were_numbered_by_place_keeps_their_numbers uses that disc,
whose kernel order numbers the pieces the other way round from their place (the post's
side of multi-body-join-cut is one face now).

- shell_tangent_chain_that_opens_every_face_explains_how_to_keep_walls: the shell is the
rounded box (its 37 x 27 x 57 core grown by the 1.5 ball: 71753.436) less the sharp 36 x 56
x 28 cavity, 15305.436, to the measure's 2e-7 (SMLib: 15305.445); truck's was 15305.28.
- press_pull_on_curved_faces: the shell's inner wall behind a fillet is offset as a face
(SMLib builds it, truck refused it as tangent to its neighbours): pulled 0.5 into the
cavity it adds exactly the quarter ring π/4 (3² - 2.5²) 18 = 38.877.
- revolve_cut_round_a_box_corner_does_not_panic: the side face is picked by its point; the
report's face index was truck's face order (SMLib's face 1 is the opposite side).

SMLib keeps a whole cylinder (and an arc of one past half a turn) as one face closed on its
seam, where truck split it in two; its holes are exact circles; its mass properties come
within 2e-7 of a closed form. The tests that counted truck's pieces or its polygon hole now
check the exact geometry:
- extrude_of_adjacent_profiles_has_whole_edges: the cut-off cylinder is 4 faces (arc side
4674 = 40·(2π − 1.2019)·23, chord side 1039.8, two ends);
- step_export_of_an_enclosure_with_a_screw_hole: 27 faces, as the file holds them;
- model_faces_gives_a_point...: the hole's wall is one cylinder, its centroid on the axis;
- draft_takes_a_cylinders_side_by_name: one side face (the draft itself waits for SMLib's
draft of a cylinder);
- convert_to_sheet_metal_takes_the_plates_face_by_name: 15000 − 62.5π to the measure's 2e-7;
- a_checkpoint_survives_file_new: a unit box measures 1 + 2e-16;
- creating_a_component_recomputes_nothing: SMLib's boolean keeps the face certificate the old
setup relied on losing, so the legacy face plane is made as a design saved before face
attachments were certified (its anchor removed) and reopened.

Since the section hatch per part (#8529), a cut is tinted toward the hatch colour its body's
name picks; Body1 picks the steel one, so the cap test's warm pixels were none
(cpu_picture_section_caps_hide_the_inside). The test turns the part hatch off: it checks that
the cap hides the inside and shows its colour, which the hatch tests cover per part.

solid.shell takes faces: [] since 1df330c79 (a closed hollow body), so its row in

SMLib makes a torus one face, so the face at (25, 0, 0) was the whole torus,
not a patch within half a turn each way. The patch is now the torus's piece
with x, y > 0 and z > 1, bounded by iso lines both ways (planes through the
axis, and z = 1 round the tube), and its thickened volume is the formula's
over the angles its mesh spans. (The sphere cap above it builds once SMLib's
offset takes an open edge's second trim point away from its first: SMLib
devgreen-kernel-geometry; waits for the pin.)

SMLib thickens a sheet across a convex sharp edge as other CAD does: each
face's offset is extended until the offsets meet (and trimmed where they
cross inward), where truck bridged the gap with a wedge. Owner decision:
keep SMLib's result. The exact values:
- three faces of a 10 box's corner out by 1: three slabs, a 1 × 1 × 10 block
along each edge and a unit cube at the corner, 300 + 30 + 1 = 11³ − 10³;
- into the inside corner by 1: 10³ − 9³ (it was refused); half each way:
10.5³ − 9.5³ (refused too);
- two faces across one edge: 2 · 100 + 1 · 1 · 10 = 210.

A sweep along points follows the lines between them (no wall is fitted through
the points, sweep_sheet_points' contract, as sweeps_along_3d_paths already
says): along a quarter circle of 41 points the sheet is a wall per line, 40,
its area 10 × the polyline's length (within 10⁻⁴ of 10 × 15π); the bent chain
is 2 × 40 walls sharing every seam, 2·41 + 3·40 edges.
SMLib's sweep takes guide rails along a cornered path when each rail turns
with the path at its corners; a straight rail along a bent path is refused
for that reason, not as "guide rails along a path with sharp corners".

SMLib revolves the cone frustum's sheet over angles 0…1 as one face, where
truck made two of half a radian each; the face's own span is angles 0…1 by
profile parameters 0…0.8: √125 · ∫₀^0.8 (5 + 5t) dt = √125 · 5.6.

SMLib makes a cylinder's side one face closed round its seam, and a sphere one
face; the tests picked "one half" of the side or "one sixth" of the sphere, which
were truck's pieces. The offset test moves the whole side (one face, area
2π·12·20); the thicken test takes half the side from a cylinder split at x = 0
(π·(11² − 10²)/2·20) and the whole side inward (π·(10² − 9²)·20); the sphere
test takes the cap above z = 5 (solid angle π: π/3·(11³ − 10³)).

prism_measure's uncertain-material check built a 20 x 20 x 1e-5 box and asked that it get no
cap certificate. SMLib refuses that box (its loops fail SMLib's orientation check): at 1e-5 it

edge_at (matchsurf) and the mixed fillet mitre check evaluated `e.curve` at parameters from
`e.interval`, which is the interval on the edge's NURBS form when it has one (SMLib's edges
do): they picked and sampled the wrong points. They now evaluate `e.parameters()`, as the fill
helpers do since aa534cc6d's fix on the kernel-geometry branch. (Both tests still fail, for
their own causes: the G2/G3 match leaves a curvature jump of 2 at the seam, and SMLib's mixed
blend lies 4e-7 off its section circle.)

Truck split what it swept: a big arc into two faces, a full circle into halves, a turn into
two or three parts, a sphere into six patches, a torus into six; it numbered boxes' faces in its
own order and sewed stepped cuts slab by slab. SMLib sweeps each profile segment into one face,
closes a full cylinder, sphere or torus along one seam edge, and cuts without slabs. The record,
face source, helix, display mesh, measure and boolean history tests still expected truck's
pieces. Each expectation now follows the geometry, checked by the tests' own independent
measures: every face's origin against the profile segment its mesh lies over (unchanged),
faces picked by where they lie instead of by truck's face numbers, and the merged counts by the
kernel-cases ladder's rule (each whole curve once, and each cylinder's seam): a cylinder 3
faces, 3 edges, 2 vertices; a ball cut from a slab 7, 14, 10. The truck-only stepped-prism
check (walls coalesced across slabs) becomes the property it stood for: the stock's walls stay
whole, one face each, Kept.

Seg2::closest_param starts Newton from the nearest of 65 samples. On a closed segment (a full
circle) the start and end samples are one point and the first wins the tie; for a point just
before the start (in the sweep's sense) Newton then wants a parameter below 0, the clamp holds
it at 0, and the answer is the start point, off by up to a sample spacing (0.15 mm on a 5 mm
circle). The record tests' face-to-segment matching read an SMLib cylinder's side as lying
over no segment because of it. A closed segment whose answer lands on an end now also tries
Newton from the other end and keeps the nearer; every other answer is bit for bit as before.

picked_edges_give_the_sketch_s_table picked [E + R, 0, 5]: on SMLib's extruded circle that is the

a_face_picked_by_point_on_a_block_with_a_modelled_thread_is_found guarded #6720 (the face search
charged the whole mesh once per face) with a modelled thread's 5 000 facets. On SMLib a modelled
thread is a few exact helical faces, so the block had nowhere near the 1000 faces the test
asserts, and the case no longer reached the old charge. A block drilled with 16 x 16 holes does:
the test now asserts its faces times its mesh's triangles is past the search's 2 000 000 budget
(the old charge) while their sum is well inside it (the new), then picks its top by point.

intersect_keeps_its_exact_cuts pinned the tilted cylinder's section to 21 segments and one
segment's ends to 1e-4: the crossings of truck's mesh. The cut is the mesh's segments, as many
as the tessellation crosses (20 on SMLib's), each end within the section's reach of the surface,
the display tolerance (a thousandth of the mesh's size, doc::project::fit_segments; SMLib's ends
lie 6e-4 off at most, the test's limit is 0.051). The test now checks that every curve is a
line, at least 16 of them, and every end lies that close to the cylinder of radius 5.

ids_names_suppression_marker_and_failures_survive needs a feature that a parameter change makes
fail, to see the failure survive the script's replay. It made a 1 mm round 50 mm, which truck
refused as too big; SMLib builds a convex round wider than its faces by subtraction (the owner's
overflow decision), so that round now succeeds. A radius of -1 mm fails on any kernel, and the
replay still has to keep the failing feature, its id and its marker.

- An SMLib circle edge's `interval` is on its NURBS form (`Edge::parameters`), and an analytic
face's `domain` on the form's (u, v). edges_are_on_smlibs_curves evaluated `curve` at the
form's interval and took the domain for angles; it checks the side's whole turn and height
on the form and a rim's turn by `curve_interval`. The tangent hole test's edge middles were
read the same way (the copy seemed to join faces on opposite sides of the line).
- kernel::chamfer blends the edges it is given; a feature's pick is extended by
kernel::tangent_chain first (doc eval). The chamfer tests do the same:
one_chamfer_pick_follows_the_tangent_chain_at_any_part_size removes its 54.66 mm³ again.
- Since the section hatch per part (#8529) a cut is tinted with the hatch colour its body's

(2885f101b on devgreen-engine-builds).

truck made a cylinder's wall and rims in halves; SMLib makes one wall face and one closed edge
per rim (one face per profile segment, a circle being one closed curve since 09c979a4b). The

(circular_rim_hover_click..., circular_items_measure..., curved_face_hover..._cross_the_seam,
a_rim_clicked_once_is_one_item_not_its_pieces) now build their cylinder from a circle drawn as
two half arcs, extruded, so the pieces they test exist. A ring's outer circle is one wall face
(configuration_annulus_picker...: 1, was 2). The certified small crease is no longer taken for
a seam (truck's coarse fit did; the seam flags compare exact surfaces now) and, a kink of a
millionth, is smooth for the shading while still a measured crease: sharp, drawn in wireframe,
picked (smooth_edges::Join).

- The shaft's rim was picked at its polyline's first point, the vertex where the wall's seam
meets it, as near the seam as the rim; SMLib's cylinder lists the seam first, so the pick
took it ("the edge is not circular", "the revolve axis does not lie in the sketch plane").
The rim is picked at its middle.
- The gear discs touch at x = 10, on both walls; G1 is picked on its far side.
- 366b90597 refuses a thread of some length picked in the middle of a face free at both ends

Builds before format 14 named the pieces a cut splits a body into in truck's shell order, and
the later features of such a design name the piece they work on by that name. SMLib orders the
pieces otherwise, so split-body-pieces' fillet and chamfer landed on the wrong piece, its
reference "no longer exists" (design_corpus body_names_saved_before_exact_history_keep_their_pieces,
old_designs_open_and_evaluate_as_saved). For a feature saved so (`shell_piece_order`), each
name its pieces are known by goes to the piece the points the later features naming it picked
lie on; a name no later feature uses keeps SMLib's order, and so do all of them where the picks
do not tell the pieces apart. docs/compatibility.md says so.
That makes the feature's result depend on features after it, which neither its fingerprint nor
its cache key cover: a script replays the design one feature at a time, so the split was
evaluated before the fillet and chamfer existed, kept SMLib's order, and was reused once they
came (script_roundtrip corpus_designs_replay_from_their_scripts: 'Body1 (1)' 4765.663706234679
opened against 4765.663706134907 replayed). The state now keeps a digest of the picks it named
the pieces by (`ModelState::legacy_picks`), and every reuse (the last results, the cache, the
kept, rolled-back and primed results) takes a state for such a feature only while the design's
later features pick the same, so the replay names the pieces again as the file does when it
opens. A saved model's states carry no lineage and are taken as saved.

SMLib's draft extrusion takes one loop, so a tapered extrude of a region with holes was refused
("SMLib draft extrusion of a profile with holes"), and designs that use one no longer opened
(modern-plastic's Rest: design_corpus, action_matrix a_small_hole_through_the_wall_of_a_plastic_rest).
As other CAD does, every wall now leans by the taper relative to the pull on the material's
side: the outer loop is drafted, and each hole, taken counter-clockwise, is drafted the other
way and cut from it, so a taper that narrows the outer boundary widens the holes. Exact: each
loop is SMLib's draft extrusion of it, the walls' roles are found as the foot's are. Refused,
saying why, where the taper would make a hole meet the outer wall or another hole at either
end of the extrusion.
Test: a 40 mm square with a 10 mm square hole, 30 up at 5° inward, is the one frustum less the
other to 1e-6 with ten faces; at 30° the hole would pass the outer wall and is refused.

17-loft's expected values were FreeCAD's (OpenCASCADE's Part.makeLoft), which runs each side of
the square to its quarter of the circle at uniform angle (arc length). That correspondence has
no exact rational B-spline form, and SolidCraft keeps its surfaces exact: its ruled loft runs
each side to one rational quarter of the circle's B-spline by their own parameters, 35080.7251
mm^3, 0.13% less (the oracle failed on volume and the second moments). The owner chose this
correspondence. The case is now worked out in tools/oracle-analytic/cases_basic.py: the section
area is quadratic in t with the loops' mixed area, so volume and centroid are closed forms of it
(the mixed area and the wall area by Gauss-Legendre on the exact rational arcs); its note says
why it differs from OpenCASCADE and gives that volume, and its `compare` leaves out the surface
check against OpenCASCADE's reference.stl. All its checks pass.

chamfer_the_top_lip_at_a_tangent_wall_junction measured the removed volume as the difference of
two meshes at chord 0.0005. The display planner meshes the two bodies differently, so their
chord errors no longer cancel as truck's meshes did: 37.404, 37.672, 37.761 and 37.759 mm³ at
chords 0.002, 0.0005, 0.0001 and 0.00003, converging on the expected 37.762 (the chamfer as the
chord between the contact lines of a 2 mm ball, integrated exactly). SMLib's chamfer is that
one; the test measures at chord 0.0001.

The display mesh is the tessellation planner's (8b6bfc48c: the mesher plans a schema 4
record), which grids a planar face with no side longer than a fifth of the body's extent
(docs/capabilities.md, "Display meshes"); truck's mesher gave a box face two triangles. The
tests that counted truck's mesh now count the planner's, worked out by hand from that rule:
- a 10 x 20 x 30 box (37.4 mm diagonal): edges in 2, 3 and 5 pieces, faces of 2 x 3, 2 x 5
and 3 x 5 cells, 124 triangles; welded, the box lattice's 3 x 4 x 6 nodes less the
1 x 2 x 4 inside it, 64 positions (obj_export_is_welded_and_keeps_names);
- a 20 x 15 x 10 box: 4 x 3, 4 x 2 and 3 x 2 cells, 104 triangles (an_opacity_class_change...);
- a 20 x 20 x 10 box saved as a mesh: its edges in 4 and 2 pieces, 40 segments per box
(imported_mesh_edges_draw_in_each_style...);
- the cylinder's top cap is under a third of its triangles (select_other_over_a_dense_cluster...).
An imported mesh's outline was one line per crease side, so a box exported at that spacing
showed each edge in pieces: a click on a 10 mm edge measured 5 mm, or hit the node between
two pieces (measure_imported_stl_edges_and_vertices..., mesh_outline_hover_cache...). Outline
sides that run straight on through a vertex no other outline side meets are now one line, as
the CAD model's edge was.

A face's edges are projected exactly: lines, and arcs read off SMLib's NURBS within the
planar-edge tolerance (Body::planar_edges). An SMLib shell's offset corner is a NURBS whose
arc came out with its centre 2e-6 mm off and its ends up to 6e-7 mm from the lines they meet,
beyond the link's merge tolerance (1e-7): the inner loop of the sensor enclosure's case top
projected as sixteen loose curves, the offset of one found no chain to follow, and the Lid lip
extrude found no profile l13..a16 (the five acceptance scenarios, action_matrix
an_axis_through_a_corner_round_that_a_parameter_moves). Each edge's pieces now end on the
edge's vertices where they lie within the edge's and the reading's tolerance of them (the
vertex is the point both edges share), and an arc whose ends moved takes the centre nearest

A round face's box (form::extent) unwrapped each periodic parameter from one boundary point to
the next. Through a pole the loop goes on from anywhere round the direction the pole collapses:
a hemisphere bounded by its rim and its seam put its second seam use on the first and its box a
quarter turn off the seam, while its pcurves ran from the seam. Past the first pole the loop is
now moved the whole periods that close it. Reference case 14's re-imported dimple had a
quarter of its area missing (9601 against 9706 mm2).

A field scrolled out of a dialog's field area still published its handle at the centre of its
whole rect. The tapped hole's dialog has grown (thread hand, tap drill, thread end rows) past
1000 px, so its section's Thread depth field scrolls under the footer, and a click on that
handle pressed OK: the edit was applied (tapped_thread_depth_field_keeps_focus_and_typing_...
saw the model change at the click; focusing a field commits nothing). A field's handle is now
the middle of its visible part and is left out when none of it shows, so a scenario can only
click where a user could; the rect keeps its whole extent. The test opens a window tall enough
for the section.

Sketch::bounds took the points of each segment's polyline. Since 09c979a4b a whole circle is
one closed arc whose chords start at its start angle, so none lands on the circle's left or
bottom: a radius 5 circle at (-300, 0) spanned x from -304.50, and Home and Fit framed short
of it (home_and_fit_frame_the_moved_body_not_its_old_place). An arc's bounds now add the
quarter points of its circle it sweeps through, which are exact.

a_face_engraved_with_text_projects_its_letters_exactly_and_extrudes counted the letters' pieces
as control-point splines. A TrueType outline's curves are quadratic Béziers, which are parabolic
arcs, and the cut made on SMLib keeps them exact: the projection gives 222 conics and 154 lines,
no splines. The count now takes conics with the splines. (The cut itself needs SMLib 1a1bebc;
with it the test passes.)

loft_cut_through_a_shelled_basin_in_either_order asserted one body. The loft's top section is
the basin's full 100 x 60 outline at z = 10, so the cut takes the walls' whole cross-section
there and leaves the walls above (z 10 to 30) touching the rest only along their outer rim, an
edge: two pieces, which a cut makes two bodies (eval's lumps rule). SMLib gives exactly that;
truck kept them as one. The test now expects two bodies, the upper one the walls' exact
924 mm² ring times 20 = 18480 mm³, and the total as before (41582.028).

a_face_sketch_saved_with_fitted_letters_reopens_and_builds_the_same compared the part with the

the saved figure was 8e-3 off. The test now checks that closed form to SMLib's 1e-8, and counts
the letter's exact pieces as conics or splines (its quadratic Béziers come in as conics).

map_planar_sources took every plane of a cut's tool as competing with an input face on it,
facing either way, and dropped that face's exact role. A text pocketed 1 mm down from a block's
top has its tool's top on the top's plane facing up, as the top does; the top then lost its
CertifiedExtrudeCap, and the sketch on it reported "the top cap of Extrude1 no longer exists"
(a_face_sketch_saved_with_fitted_letters_reopens_and_builds_the_same). A cut's tool faces enter
the result turned round, as the walls of the hollow, so a tool face can only take the place of a
face on its plane facing against it (a pocket's floor, a face the tool sat on from outside). Only
that orientation competes now; the existing blocking cases (a tool's bottom on a pocket floor, a
tool face against a wall) are unchanged.

unsupported_face_has_explicit_fixed_alternative_and_no_live_projection needs a planar face with
neither a construction certificate nor an exact history name, so a sketch on it must be fixed.
Its face, a split top face offset up, now keeps its history through SMLib's offset and gets a
name. A rib reports no roles for the faces it builds (Traced::unnamed, eval_more), so a rib's
wall has neither: the test now picks the wall at y = 12 of a rib in a bracket's corner.

interference_lists_a_pair_it_could_not_check needed a pair interference cannot check. Its
pair, an arc revolved up to a post's wall, was one truck could not intersect ("not verified");
SMLib intersects it exactly, and that reason is gone from the code. The pairs left unchecked
are a kernel failure, the time budget, and a mesh body: an imported mesh has no exact surfaces
to intersect (owner's call). The ring is now brought in as an STL beside the post, and the pair
is listed with "mesh body: not checked" instead of passing as clear.

freezing_rebuilt_arc_borders_keeps_authored_dimension_entity_indices needs the projected
border of the sketch's face to come back with a different number of curves. Truck split the
sector's arc into pieces that changed with its sweep (270 to 300 degrees); SMLib keeps one arc
whatever the sweep, so the count stayed 3. A notch, clear of the sector until a parameter moves
it across the arc at 90 degrees, now splits the arc border into two arcs and the notch's sides.

same_support took two planes as one support only within 4096 ulps (normals 9e-13 apart,
origins about 1e-12). Faces SMLib rebuilds through a boolean lie within its own resolution of
the plane they were made on, not within ulps: a cap at z = 10 notched by a cut came back with
its origin 2.1e-11 off and its frame turned 1.36e-12 rad, so its CertifiedExtrudeCap was
dropped and the sketch on it reported "the top cap of Extrude1 no longer exists".
Supports are now compared at SMLib's own coincidence rule, SmPlane::CoincidenceCheck: normals
within the angle the tolerance makes across the plane (`tolerance / size`) and each origin within
the tolerance of the other plane, the tolerance being the record's `tolerance` (SMLib's per-brep
XSectTol3d, the one its booleans test surfaces for coincidence with). The body's size stands
for the plane's extent (at least as large, so no looser); rounding stays the floor. The normal
window the candidates are searched in follows the same angle.

The truck booleans answered a tool clear of the body without intersecting (the operand kept,
its record shared). The SMLib boolean always rebuilt the body, so a cut that could not reach a
body still handed back a new record: a hole far from a second body reported that body changed
(#2904's test), and a body clear of a pocket's cutter was no longer the same solid. A cut or
intersection whose operands are apart (their exact boxes, grown by twice the tolerance as
union_apart takes them, do not meet) now gives the body itself with its faces and edges kept,
or nothing, with no SMLib call.

- A section's chains are walked from either end, whichever segment the mesh's triangle order
puts first at a node (doc::project::fit_segments), so a line's direction says nothing about
the cut. SMLib's box tessellates in another order and the outline came out clockwise: the
same four lines. The two box-outline tests now compare each line with its lower end first.
- The base rim of SMLib's cylinder is one closed circle edge (truck's was two seam halves), so
projecting it gives one exact ellipse. Checked against the closed form: a radius-5 circle in
a plane tilted 45° projects to semi-axes 5 and 5·cos 45° = 3.5355339 (the reported minor
radius), and every sampled point lies on x²/(5/√2)² + y²/5² = 1 within 1e-9, as before.

Linking a reference (sketch.include_3d, project, intersect) stored the link's wires as points
only: add_link_unless_present called add_link_with_wires and dropped the resolution's exact
curves, which only the next refresh of the sketch filled in (doc::project, since 7952516eb).
So an included box edge had no exact line until any edit refreshed it, and the wire changed
under an unrelated sketch edit. The exact curves are now set with the wires when the link is
made, as a refresh sets them.

Two readings of the SMLib record went wrong in emboss_cylinder:
- The footprint arcs were labelled on the sketch's radial frame. The assembly gives each new
circle edge the NURBS form on its label's quarter grid, and the wall face keeps its own form on
its frame's grid (a cylinder's seam lies at an odd angle, build::SEAM_ANGLE). The two grids
differ by a non-quarter turn, so the arc's form is not a straight line in the face's (u, v)
and no exact pcurve exists: "no exact pcurve of a NURBS on a spline surface". The arcs at the
wall's radius are now labelled on the wall face's frame (form::on_frame), so their forms lie on
the face's grid and the pcurve is exact.
- wall_angles took the edge's interval as the circle's angles. On an SMLib record the interval
is on the edge's NURBS form (2πr long for a whole turn), so a wall spanned some 63 rad: a
profile across the seam was accepted, and a wall of radius 0.1 was refused as off its seam.
It now reads Edge::curve_interval.

A face that meets itself along a line (the Pinch case's boss side, turned 30 degrees: the hole's
wall touches it along a vertical line from the hole's bottom to the top rim) has its loop run up
that line and back down. Its motorcycle trace runs from the slit's tip to the bottom and the
iso-line grid meshes it, but the band between the grid cells and the boundary was filled by a
parity flood that flipped at every constraint, the slit's too: the band on one side of the slit
was taken for outside, the face did not follow its boundary, and the lenient fill took over.
The band now crosses a side the loops run along both ways without counting it, as the
triangulation itself already did. Delaunay's sag refinement had the same flood and left the far
side of a slit unrefined (the lenient fill's 0.52 mm^3 shortfall); it takes the slits too.
The Pinch case now meshes strictly: the boss side is 628.3177 mm^2 against 200 pi = 628.3185, and
hole_tangent_inside_a_stepped_boss_cuts_exactly passes. New tess test: a square with a slit
meshed by the cut grid follows the slit both ways and covers the square's area exactly.

Where a face meets itself along a line (a hole's wall tangent inside the wall round it: the
boss side touched by the hole along a vertical line, run up and back down), its loop runs along
that line both ways. The triangulation's region test flipped inside and outside at every
constraint side, so crossing the slit put the face's far side outside it; the follow check
wanted every boundary side under exactly one triangle, where a slit has one each side. Sides the
loops run along an even number of times no longer flip the region, and the follow check wants a
triangle per run. (The Pinch case's boss side still falls back to the lenient fill, now within
0.52 mm^3 of the exact 8717.92 where it was 340 short; the strict fill's remaining mismatch on
the seam-cut face is open.)

A ring whose inner circle touches the outer one (a boss standing on a disc, tangent inside its
rim) is one loop through the touching vertex, both circles leaving it along one tangent. There
the inner circle's first node falls on the outer circle's last chord whenever the outer chord is
twice the inner (exactly but for the next order: the inner circle at s rises s^2 / 2r, the outer
chord at s/2 of its length rises L^2 / 8R, equal for L = 2l, R = 2r), as the samplings fell
here. No crossing by the untangle test, but no triangulation can keep both as constraints: the
strict fill refused the face, and the lenient one, dropping constraints, filled the inner disc
(314 of the ring's 942 mm^2, the Pinch test's 1047 mm^3 shortfall). A node of one chord lying on
another (inside it, not at its ends, and not two chords along one line, as a seam's two uses a
period apart are) now has that chord halved. Regression test: the ring meshes strictly, to
300 pi.

fillet_an_open_curved_edge, fillet_sharp_arc_and_arc_loop and
fillet_mixed_arc_and_line_removed_volume_converges took the volume a round removes as the
difference of two mesh volumes, which magnifies their sag (each mesh lies within its chord of its
faces, so the difference can be off by both areas times the chord: for the r 0.25 round at a
1e-4 chord 1.8e-3 of what it removes). Measured exactly (SMLib, 1e-8) the rounds are right:
the open curved edge's removal 25.7629198 against Pappus' 25.7629199, the sharp arc loop's against
its lens quadrature, the mixed joint's 2.7155830 and 0.6842666 against the reference 2.7155785 and
0.6842658 (1.7e-6 and 1.2e-6: the blend's own fit, whose section error the joint test reports).
The removals are now exact, the mixed one held to 1e-5 of the reference; the meshes' removal is
held to its chord bound of the exact one.

Support::station reads the curve leaving a boundary from five samples: one-sided where the
support ends at the station, central where the surface goes on past it. The central five-point
formulas had the first and second derivatives' signs reversed ((-f0 + 8 f1 - 8 f3 + f4) and
(f0 - 16 f1 + 30 f2 - 16 f3 + f4) over 12h, 12h^2, the negatives of the standard ones), so the
curvature read there pointed away from where the surface bends. Truck's half cylinders ended at
every picked line and read one-sided; SMLib's cylinder is one periodic face, the seam is inside it,
and the central branch read the wall bending outward (+radial / R): the G2 and G3 matches to it
built sheets bending the wrong way, and the continuity check, reading the same frames, called
them G2. The central formulas are now the standard ones.

measure now integrates to SMLib's finest relative accuracy, 1e-8 (da57f37e5, cherry-picked from

measure asked SMLib for a relative accuracy of 1e-4, after SmApiBrepComputeMassProperties'
documented clamp to [1e-4, 1e-1]. smlib_brep_mass_properties does not go through that call: it
calls the kernel's integration directly because the clamp "leaves curved faces off by 1e-5 to
1e-3", and takes [1e-8, 1e-1] (solidcraft_smlib::MEASURE_ACCURACY). Asking 1e-4 threw that
away: a swept cylinder's centre came out 5e-7 off its exact place, and a 0.0177 mm³ crescent
(a pin 0.59 µm off its hole) 0.27% off the lens of two circles. Measured at 1e-8, the sweep
centres are exact to 1e-7 and the crescents match the closed form to 1e-6; the engine-commands

a_lip_swept_on_a_round_rim_joins_it compared the union's mesh volume with the two operands' at a

faceted_cut_of_a_helical_groove took the volume removed as the shaft's exact volume less the cut
body's mesh volume at a 0.01 mm chord. That mesh sags inside the shaft's round wall: the uncut
shaft's own mesh at 0.01 is 0.18 mm³ short of pi r^2 h, five times the 3 % the groove is held

faceted_boolean took the tool mesh's triangles by vertex index and refused any edge not shared

faces meet has a Meet origin by the history's contract (EdgeOrigin::Meet), and SMLib's history
gives them: the raised band's and the thickened sheet's new edges. It now checks the edges an
operand still owns and passes over the meetings. The thickened sheet is the whole cylinder side
(SMLib's one face, truck's half): a wall stands along each of its free edges, the two rims, and
none along its seam, which the face meets itself along (2 + 2 faces, not 2 + its 3 edges).

A layout can leave triangles standing on their long side across the surface:
their corners on it, their plane across it. They count several times the area
under them (the front triangle's loft tubes 0.7% and 1.1% over the finer mesh)
and no split repairs them, since each half stands the same way.
After the sag refinement a post-pass flips a side inside the face when the
two triangles on it turn less from the surface normal the other way (by more
than a degree), keep their orientation in (u, v) and against the surface
normal (nothing folds), have area in 3D, and the new side and triangle middles
stay within the tolerance of the surface or no farther than before. Boundary
sides are never flipped.

Refinement split the side of a triangle that sagged most. Where a long
inner side lies on the surface at its middle (a section with an inflection,
a loft tube of the bike frame's front triangle) and the triangle's short
sides sag, only the short sides were split: each split left a child with the
long side and its vertex nearer to it, and the triangle beside a split side
lost its shape the same way. The triangles flattened onto the long side
without end, refinement ran to its point budget, and the mesh of the face
counted 3.4 times its area (1.45 times on a second tube).
A triangle whose widest angle is past 150 degrees now splits its longest
side, and a split never goes across an obtuse triangle's shorter side: that
triangle's longest side is split first, along the path (Rivara's
longest-edge propagation, its lengths growing, so it ends). Only sides inside
the face are split, as before.
Test: tess sag_refinement_across_an_inflection_ends_without_slivers, a sheet

middle; it ran to its budget of 20000 points before and adds 28 now.

A whole sphere as one face has its seam as its only edge, used both ways. In a body many times
its size the seam gets two segments at the body's chord (pole, equator, pole), so no node off
the poles follows a node off them, and the loop kept its first node, a pole: its closing step
crossed the other pole, which the drift unwrapped to a whole turn ("boundary winds around the
surface"). The sphere was left out of the mesh (cut_beside_a_sealed_void_keeps_the_body: a void
r 2 in a 75 mm part, "1 face(s) don't mesh"). The loop now starts, failing a node with an
off-pole predecessor, at a node whose predecessor is a pole on the same edge, so the step into
it is that edge's own and the step into the pole is unwrapped in the loop like any other.

export_keeps_faces_split_on_purpose took a box whose top Split Face cut in two, dropped the
split record by hand (with_split_lines(None)) and expected the STEP file to have 6 faces: truck's
export joined pieces on one surface, "as it does for pieces a boolean left". No operation makes
such a body: the split record is only set (doc eval, Split Face), never dropped, and removing a
Split Face rebuilds the part without the split. SMLib's booleans join pieces on one surface at
their end (two touching boxes unite into 6 faces), and the local modifiers heal through
boolean_record::healed, so no operation leaves incidental pieces either. The file now has what the
body has (7 faces, the export merges nothing), and the heal every later operation applies
joins the unrecorded pieces: 6 faces in the body and in its file.

SMLib's cylinder side is one face round the whole turn (truck's two halves): a line at z = 5

a_modelled_thread_in_a_bore_meshes_inside_its_block held each face's triangle area to within 5%
of its surface's area. At the 0.1 mm tolerance, face 18 failed that: 1.777 mm^2 of triangles
over 1.522 mm^2 of surface. Face 18 is the groove's crest band where it runs out through the
block's end, a wedge at most 0.44 mm wide. Its boundary sides are the helix edge's chords, 1.37
mm long and sagging 0.062 mm (inside the tolerance). A flat triangle on such a chord bridges the
sail between the chord and the edge instead of following it, and the band is no wider than the
sag. The excess, 0.255 mm^2, is less than the sails along the face's boundary (sum of 2/3 L sag
= 0.62 mm^2). Every triangle is within the tolerance: the chord check passes. No triangulation
of the inside changes this; the boundary nodes are the shared edge nodes.
The check now allows 5% plus the boundary's sails at the tolerance, 2/3 L tol per boundary side.
A zigzag that multiplies a face's area, which this test exists to catch, is still far outside
that. On the run-out root band the bound allows about 40% at 0.1 mm and 5% plus 4 mm^2 at
0.01 mm, against the former 6x.

curvature-keeping taper builds it as mainstream CAD does: each wall continues as itself until it
meets its neighbour. The test now checks what was built. The section at d = z tan 8 deg is the
disc of radius r + d over x >= -d, y >= -d. Its area is in closed form, and the volume is its
integral by Gauss-Legendre: 458.5870559 against SMLib's 458.5870567 (2e-9). The body has 5 faces.

thread_display_tests sewed its M10 and M12 threads from cubic Bezier pieces approximating
helices, which lie about 1e-5 mm off the core and crest cylinders. No exact (same-parameter)
pcurve exists on the cylinder for such an edge, and SolidCraft's pcurves are exact B-splines
only. Sewing refused the core face ("no exact pcurve of a B-spline on a spline surface"). Truck
had fitted one. The thread feature makes its helices exactly, with SMLib's screw sweep, so the
test now does the same: the ISO ridge's section is screw-swept and joined to the core cylinder.
The section reaches a tenth of a pitch into the core along its flanks. ridge_volume is still the
thread's exact volume, and both display tests run unchanged, from the body as made and after a
STEP round trip. Imported edges that lie off their surfaces stay refused; they are Repair Part's
job.
The quality check's sag is now measured at the surface point nearest each triangle's centre.
Before, it was read at the mean of the corners' parameters. A closed surface's parameters are
kept within one period, so a triangle across the core's seam had corners a period apart, and
their mean read 6.27 mm off a triangle that lies on the surface.

isocurves_of_a_split_face_run_on_across_the_split split the box's front face at x = -2
and 22, leaving an 8 mm piece. Since a body's size counts its edges (the boss's rims
reach y = -32 and z = 50), the lines' spacing grew to 10 (x = -20, -10 on the left
piece), and the 8 mm piece had no line up it to compare. The boss now leaves pieces
x < -6 and x > 18, room for two lines and one: the test still checks that both pieces'
lines lie on one ladder.

Body size (the box diagonal every size-relative tolerance comes from: mesh chords, reach,
fit tolerances) came from the record's vertices alone. SMLib closes a sphere, a cylinder or a
torus along seam edges, so those vertices can be two poles, two seam ends or a single point: a
torus was 1 mm across (its preview at a hundredth of that took 214 720 triangles and broke the
budget), a 5 x 8 cylinder 8 instead of 16.2. The size now also takes three points along each
edge: points on the edges, not their control hulls, which for a rational edge can lie far off
it (a sheared L-prism's outline box was 49 km across).

sample_aliasing_does_not_certify_spline_caps built its trap as one polynomial of degree 17 with
a root at each of the 17 old sample locations k/16 (and a circle times such a polynomial, degree
19). A B-rep record holds splines up to degree 16 (MAX_SPLINE_DEGREE, #8618), so no record can
carry either and the evaluator refuses them: the test failed before testing anything. The trap
is now a C0 spline with a knot at every k/16: a quadratic on the line at each knot, bowing 1 mm
off it half way along the first span; and the quarter circle of radius 10 with its homogeneous
coordinates scaled by 1 + bump / 10, radius 10 at every knot and 11 at 1/32. Sampling at the old
locations still sees a line and a circle; the certifier, reading the spans' control points,
must certify neither, and doesn't.

genuine_curves_and_oriented_traversal_are_certified built its degree-elevated line at degree

no such edge reaches the certifier, and the evaluator refuses to build it. The line is now
written at MAX_SPLINE_DEGREE: still a line of the highest degree a record can carry.

The smooth-path sweep named walls only by the profile's edges in the start plane and took any
planar face nothing claimed for the end cap. A wall the start plane meets along no edge got
no name or became a cap: round a closed path, a square tube's planar top and bottom (whole
annuli, no seam) were both called end caps; along a line then an arc, the walls SMLib makes
along the arc were unnamed or caps. Like the cornered and controlled sweeps, it now also names
walls by the profile carried half way along, takes the end cap from where SMLib carries the
profile last, and round a closed path has no caps at all.
The issue #2005 tube check counted V - E + F without the ring term: SMLib's annular planar
faces have two loops each, so it checks V - E + F - (L - F) = 2 - 2g (Euler-Poincare). Along a
line then an arc SMLib makes a wall per profile segment per path segment (two, where truck
made three).

transform_matrix moves a body by a matrix that is not a rigid motion through SMLib, which
numbers the moved body's faces afresh, then attached the input's face sources and paint in the
input's face order. Planar certificates landed on the wrong faces (a reflected, sheared plate's
hole walls and caps no longer lay on their certified planes). Each moved face now takes the
source and paint of the face its history names; a face with no known origin takes no source,
and with no history at all the paint stays as it was.

efd0a577b kept the cap flatness tolerance under a quarter of the gap between parallel start
and end planes. A half turn's end plane is its start plane: the gap is 0, the tolerance became
0 and neither cap was found, so m0-revolve-primitives' two flat ends could keep no sketch
attachment (design_corpus every_flat_face_of_every_corpus_design_takes_an_attached_sketch).
Only planes apart by more than rounding bound the tolerance; coinciding ones are told apart by
the profile's edges, as before.

The roles of a swept body's faces take a face as a cap when all its points lie within a
flatness tolerance of the start or end plane, sized to the body (1e-5 of it). A box 0.1 µm
thick in a 14 mm body is thinner than that, so each cap lay in both planes and box_solid
refused "box role correspondence" (engine component_clone
boundary_material_proof_requires_resolvable_stock_and_void). Between parallel start and end
planes the tolerance stays under a quarter of their gap; a cap's points lie on its plane to
the evaluation's precision. Regression case: a 10 x 10 x 1e-4 box in

Each wall of a swept body is known by a seed on its piece's edge in the start plane; every
start-plane edge within `near` of a seed took its piece, `near` sized to the body
(3 x 2e-4 of its size). On a side shorter than that the neighbours' edges are near too: a
0.3 mm wall of a 1 m label is 0.15 mm from them, near 0.65 mm, so the long walls got two
pieces, had no source, and box_solid refused "box role correspondence" (gpu depth
at_ten_metres..., engine component_clone boundary_material_proof); a ring of radii 10 and
9.999 lost its side certificates (ui configuration_annulus_picker...). A seed now marks only
the edges nearest it (within the flatness tolerance of the nearest), still within `near`.

A chamfer picked at (10, 0, 20) on a cylinder's top rim lies on the vertex where SMLib's
cylinder has its seam. The blend takes the rim there (blend_smlib::resolve: a seam or a smooth
join loses a tie), but the name stored with the feature came from the nearest mesh edge, the
seam (`F2:side:c1`). Once the stem grew, the name found the seam and SMLib refused the chamfer
(join_extrude_from_a_chamfered_top_face). edge_names_for names the edge each pick takes as a
blend takes it (kernel::blend_edges), the nearest edge only where that finds none.

face_patch put the tool face's surface (a cylinder) over the domain of its NURBS form, which
SMLib parameterises otherwise (0..1, not the angle and height), so the patch handed to SMLib
was a sliver of the cylinder or empty and SMLib refused it as an invalid argument
(split_body_by_a_face). The domain is the analytic surface's: a whole turn, unbounded along
the axis, closed past the body as before.

edge_circle took a circle edge's interval as its angle. A circle SMLib holds on its NURBS form
is parameterised on that form (a fillet's quarter circle over 0..1), so the fillet's edge
measured 57.3° and an arc length of R·1 (a_fillet_edge_is_an_arc). The span is the edge's
curve_interval, the angles of its ends on the circle, as the lip already reads it.

The thread forms (b4549d270) parse designations in thread_forms, whose refusal for a plain
M28 said "give it: M28x1" and, for M0 or M1e9, still offered a pitch. The hint the hole

now thread_forms::no_coarse_pitch, used by both; a diameter no metric thread has is an
unknown metric thread. The test's "unknown thread" follows the forms' wording ("unknown

The normal equations of patches about a centre were solved dense, so at most
500 free control points: the torus window, 1433 once its patches ran in their
own spaces, was refused. Each patch's interior (coordinates of points only it
holds, coupled by no row to another patch's) is a banded block now; the blocks
are eliminated exactly onto the unknowns the patches share (the spokes, the
centre, and the points rows across a spoke couple), whose Schur complement is
solved dense, and the interiors follow by back substitution. A solve takes up
to 6000 free points, as one patch does, and refuses past 4000 shared unknowns
(a 128 MB dense block) with that reason. The torus window and the pentagon now
solve (they fold, open).
The fill tests' own-edge check compares an edge's NURBS form to rounding, as
fill.rs's does.

About a centre, every patch ran in one space both ways that held the breaks of
every half edge and spoke, so each patch carried every edge's knots: a window
cut in a torus, its edges SMLib's traced intersections with many knots each,
needed 13537 free control points. Patch k now runs along u in the space of
spoke k − 1 and along v in that of spoke k; the space along a spoke holds the
spoke and the two edge halves it meets beside its two patches, so the spoke
is one row of both, as before. The torus window needs 1433 (still over the
dense solve's 500, open). Refinement about a centre adds the middles of one
uniform grid to every spoke's space; a patch's conditions read its own
spaces' spans, and the stations along spokes the finest of them.

The fold check refused a patch whose normal, anywhere on a grid, was a right
angle or more from the normal at its middle. A fill may turn its normal that
far without folding: a dome that meets a tube's wall tangentially is vertical
at its rim (90° from its top), a window round more than half a cylinder turns
past 120°. A fold is the surface turning back over itself, which reverses the
normal between neighbouring points of the grid (24 × 24, 3.75° steps on a
half cylinder); that is what is refused now, and a normal that vanishes
inside the patch. It may vanish at a corner where two sides run on straight
(a closed loop's pieces) and on a three-sided patch's pole.

A cup's rim of seven or eight ellipse arcs meeting at corners was too wavy for
the height-field fill: its finest grid, 32 spans across, stayed 6.4e-5 off the
loop where the tolerance is 4.4e-5 (a smooth bicubic follows the height's kink
at a corner only as closely as its cells are small), and the loop went to the
general fill, seven faces where one fits. The grids now go to 64 spans (the
fit's system is banded); the first within tolerance is still the fill.

face_tolerance (and planarity_tolerance) was 10⁻⁶ of the body's bounding-box
diagonal, which changes as a body turns: the cup turned 0.7 rad about
(1, 2, 3) grew from 54.7 to 61.6, its fill sampled to another tolerance, a
different surface (area 974.543 against 974.527). The size is now the
diameter of the smallest ball holding the vertices (solidcraft_geom::Ball,
Welzl's algorithm, expected O(n)), the same wherever the body is and however
it is turned. Twice the farthest vertex's distance from the vertices'
centroid is that too, but up to twice the body's diameter where the
vertices crowd one end: a rounded box's set-back-13 G2 corner patch then
ran 2.0e-3 past the box (corner_g2
a_long_setback_keeps_the_g2_patch_inside_the_box, limit 1e-3).
The own-edge check of the fill tests compares an edge's NURBS form to

round trip, the last bit of a coordinate apart.

The iso fill needs three sides or more, so a loop of one closed edge (a tube's
end) or two was refused as "a loop of 1 edges". Such a loop's edges are now
taken in equal pieces of their own parameters (one edge in four, two in two;
a break that falls on one of the curve's knots, a conic's quarter points, is
that knot exactly), each piece the edge's own curve segmented exactly; the
patch's edges are those pieces, their ends new vertices shared by the pieces
either side. A piece of an edge the loop runs against has its parameter
reflected about the edge's interval, as a whole edge's is.
The tube end is still refused: one four-sided patch on four quarters of a
circle has corners where its sides run on straight (180°), and the G1 dome
folds there.

A record's tolerance is SMLib's intersection tolerance: SMLib holds an edge's
gap to its faces to half of it (the zone tolerance) and a vertex's gaps to a
quarter (SM_XSECT_TO_ZONETOL3D, SmBrep::ValidateAndUpdateTolerances). The fill
gave its edges and vertices the face tolerance itself, the gap its surface is
certified to, so SMLib's check refused every fitted patch (an edge/surface gap
of 2.6e-5 against 1.85e-5 where the fit holds 3.7e-5), alone or stitched to
its body. Its edges now take twice the gap and its vertices four times.

A ruled strip off an arc whose rulings keep their angle to the arc's axis
(normal or tapered mode on a 30 degree lean) is a piece of a cone, but was
built as the rational B-spline between the arc and its image, which SMLib
labels with no analytic type (its CopyAndAddAnalytics only sees the plane
strips). Such a strip is now the start ruling turned about the arc's axis
through the arc's angle by SMLib's revolve, as the round corners already are:
a cone face, the same surface. a_circle_in_every_mode passes.

Kept parallel (the profile as drawn), a profile flattens to nothing where the
path turns to run along its plane. The check that refuses it (the path must
cross the plane by 5° or more all the way) lived in the stations of a
controlled sweep only; a plain parallel sweep went to SMLib unchecked and
built a degenerate solid. Both take the same check now, the plain sweep on
each segment's direction of travel at 33 points along it.
A circle profile is one closed arc, one edge in SMLib: a wall per path line,
not two.

Going into SMLib a sheet's shell holds both sides of each face, so the side the
record keeps as the sheet's front is lost, and SMLib thickens along the
surfaces' natural normals: Reverse Normal did not change which way a thicken
grew. A sheet used against its natural normals everywhere is thickened by the
negated thickness.

A record edge on a circle or ellipse carries the NURBS form SMLib holds it as,
its interval on that form. The patch built its loop edges from the form alone
(sew::PartEdge had no place for it), so a fill's rim came back from SMLib as a
plain B-spline rather than the body's ellipse. PartEdge now carries the form;
assemble keeps a given form and labels the edge with what it is.
Test helpers that sampled an edge on `curve` with the form's interval picked
points off the edge ("no edge at …"); they sample `parameters()`. The fill's
own-edge check compares the curve's kind and the exact form it is parameterised
on: SMLib renormalises a conic's frame axes in the last bit on a round trip.

SMLib can give a NURBS edge an interval that starts or ends a rounding past its
curve's knots: the end of the variable round r1 -> r5 run on into a box corner's
R5 round (ladder 07-fillets/012), trimmed by the R5 cylinder, started 7e-15 before
the first knot, and the record failed validation ("parameter interval outside
the natural domain"). Such an interval is moved onto the knots, as a face's
domain side is onto its surface's natural range (`onto`); farther past them is
still an error. SMLib 7e917f0 (c0d74ee..6e77631: the trace's reach set before
the corners) moved these ends by 1e-11, which is how the case regressed.

a_shown_dimension_that_breaks_a_later_feature_reports_it_and_undoes took the

face's far edge and is cut as if the face went on (the owner's overflow decision),
so it builds and the test failed. The test is about the error a dimension change
reports and its undo, so the broken feature is now a 2 thick shell open at the
top: 3 wide leaves no room inside its two walls, a refusal made before SMLib.

The arc part's front edge rounded r2, then its left top edge with tangent
propagation (the Fillet feature's default): that edge runs on round the first
round's end arc and down the left front upright, so three edges end up rounded
(a sphere octant at the corner where they meet), not two. Both results were
exact: 9530.77 (meshed) is the part less three r2 strips and the octant,
9591.44 − (0.858407·(39.1667 + 19 + 8) + 8(1 − π/6)) = 9530.83; 9538.79 is
two strips less their overlap, 9591.44 − (0.858407·62.1667 − 0.7670) =
9538.84. The test compares the sequential rounds with the same edges of the
part rounded together: the picks' chains and every edge of the part the second
chain carried on into.
The other pairs still fail in SMLib (1001, or SM_ERR_INVALID_INPUT at the
knife-edge tip) where a later round ends on the first round's arc.

The Fillet and Chamfer features already blend each picked edge's tangent chain
by default (tangent_chain, true unless saved false), as mainstream CAD's
tangent propagation does; the kernel blends exactly the edges it is given.
#8678 refused, before SMLib, every edge that runs on tangentially into one left
out, which also refused blends SMLib builds (a round ending on the round its
edge runs into: blend_corner's a_round_next_to_a_round_of_another_radius, the
same feature with propagation off). Now:
- propagation off: only the picked edges are blended; where SMLib cannot end
the blend at such a continuation, its refusal names the edge it runs into
and that propagation (tangent_chain: true) blends the chain as one;
- propagation on, where the chain cannot be built (an r3 round carried on
round an r2 round's end arc), the refusal says the chain was blended and
that with propagation off only the picked edges are.
A smooth edge is still refused before SMLib. No default changes: the feature's
default was propagation on already.
The kernel tests that stand for a Fillet feature (curvecorner's sequential
rounds, issue 2422) take each pick's tangent chain, as the feature does by
default.

A smooth edge (its faces meet tangentially) has nothing to round, and an edge

The Patch dialog's continuity row keeps each order's hover line and adds one: the patch meets

Four continuity cases for the patch fill. A hole in one smooth sheet (a cubic Bezier profile
extruded, a square trimmed out) patched g2 and g3: every seam reaches the order, corners
included, since round the hole there is one surface. The hole a three-round corner's blend
face leaves, patched g2 and g3: exactly g1 over each whole seam, since at the hole's corners
the rounds meet each other G1 (their curvatures differ by 1/4 or 1/8 per mm) and a patch smooth
there has one curvature; the middle of each seam reaches the order (kernel test).

The patch fill meets its neighbours to G4, so Construction::Patch now offers g0 to g4: the
surface.patch command takes g3 and g4 and the Patch dialog's continuity row offers
"Curvature change" and "Smooth curvature change" by itself, from the one table.
The three-round corner test patches G2, G3 and G4 and reads the seams with the Continuity
Analysis too: the middle of each seam (30-70 %) at the order asked; the whole seam G1, since at
the corners the rounds' curvatures differ and no patch can meet both.

- Space::basis_left: the basis of the piece ending at a knot.
- Orders above a corner's agreement come back smoothly over the next share of the side
instead of switching on at once.
- Orders above G1 are best effort once refinement is spent: the fill is returned with its
jumps reported; the tangent plane, the points and an unfolded fill stay hard.

- One patch has a space along u and one along v, each holding its two sides that run that way;
a side's knot keeps its continuity when raised (multiplicity m + q - p), and each side is
carried in exactly by interpolation at the space's Greville abscissae.
- Refinement halves the spans only in the direction whose sides miss, and one patch's normal
equations are banded (the shorter direction numbered fastest), so a loop with a long
intersection curve refines where it needs to.
- At a corner whose neighbours agree to a lower order than asked (their tangent planes, their
twist between the two edges, or their forms), the stations near it ask no more than that.
- A station is held to the angle tolerance beyond the edge's own lean out of its neighbour's
tangent plane: a fill that holds the edge cannot come nearer.

One order-n implementation in the linkage-curve formulation (Pegna & Wolter 1992;
Hermann, Lukacs & Wolter 1999): geom::linkage reads the neighbour as a height over its
tangent plane to order n (its jet, from the surface's exact partials of any order) and
gives each order's condition on the linkage curve, with exact gradients (dual numbers),
so fill_iso solves orders 2..n by Newton's method. Each order's row is weighed by h^(k-1)
and its jump is held, carried into the fill by Taylor's theorem, within the angle tolerance.
The iso fill takes rational edges (a circle's arc on its NURBS form): homogeneous rows,
each edge scaled so the corner weights agree, the inside weights the Coons blend and
fixed, so the fill stays a linear least-squares problem. Its degree is at least n + 1,
refinement adds simple knots, breaks of different sides within rounding are one, and the
weak Hermite rows act in the tangent plane at the Coons start's own speed, so they no
longer pull against the G1 rows.

The command worked the repair out itself for its reply and the feature worked it out again
when it evaluated. The evaluation now keeps the kernel's report on the feature's result (as
an import keeps its import report, cached with it), and the command's reply is built from
that: one repair per call, and a part with nothing to repair fails the evaluation, which
leaves the design unchanged.

A new undoable feature (`repair`, one pending format file) and command with input and
output schemas. In order:
- A cylinder, cone, sphere or torus face SMLib refuses on its own is rebuilt on a NURBS
form of its surface laid on arcs from where the face starts
(`form::surface_on_own_arcs`), with SMLib's own trims: the import's quarter-grid form of
a face round most of a turn closes on itself, which SmTorus::IsNurbSurfaceTorus does not
recognise. Geometry unchanged.
- Free edges that pair up within `gap` are sewn by SMLib's stitch; GlueEdgesGeneral gives
each glued edge its own tolerance (at least twice its gap), the body's and the other
edges' stay. The result is checked against the input's own SMLib check, the
tolerance-bound tests (#5, #6, #59, #82) exempt.
- Loops of free edges left are holes: offered as surface.patch, and with patch_holes made
(flat only when the loop is planar and every face around it is a plane, else G1) and
sewn in.
The reply reports what changed face by face; nothing to do is refused with why.

allow_errors_writes_anyway_and_a_saved_design_keeps_failing compared the box's volume
with 4000.0 to the bit, which the old kernel's closed-form planar volume gave. SMLib
integrates mass properties numerically (relative accuracy 1e-4 asked for) and gives
the 20 x 20 x 10 box within a unit or two in the last place (3999.999999999999), the
correct answer to the precision the measure has. The test now checks 4000 mm³ to a

a_combine_tool_stays_where_it_is_placed makes a part and then moves its occurrence

A body made by an SMLib operation kept that SMLib body beside its record (SMLib's
export). The export is not exact to the bit, so the kept body measured and operated a
little differently from the record's import, which is what a body read back from a
file has: a box measured 24000.000000000004 mm³ live and 24000.0 reopened, a drilled
box 21989.38056 against 21989.38013. A cut ring's volume therefore changed when it
was moved, the moved ring being measured on the SMLib body the move made
(measure_centre_tests::combine_cut_volume_does_not_depend_on_placement). Every body
now imports its record when an operation first needs it, so evaluated and reopened
bodies are the same.

The GPU path tests (and the Windows FXC job, cargo test -p solidcraft-gpu) build real
designs through solidcraft-engine, a dev-dependency without its smlib feature. Run on
their own (-p solidcraft-gpu), nothing in the build turns SMLib on, so every geometric
step answered "this build has no SMLib" (10 path::* tests on develop). The
dev-dependency now asks for engine/smlib, as the apps do, and both jobs fetch SMLib
before building.

fillet_into_an_earlier_round picked the box's upright after rounding its top edge
and expected only that edge rounded. Since solid.fillet rounds each picked edge's
tangent chain by default (84bd2daad), the upright runs on through the first round's
end arc into the top right edge, and that is rounded too. The two-radius checks now
ask for exactly the picked edges (tangent_chain: false), and a new check rounds the
chain and expects what a round of the 38 mm top right edge takes off as well.
ribs_flush_with_a_window_change_nothing_away_from_them compared the lid with
6703.5222 mm³, the old kernel's chorded volume. The lid's closed form (the plate
with its rounded corners, the skirt, less the window, the slot and the notch) is
6703.5344 mm³, which SMLib gives; the test computes it, and the script's
description says it. Each rib's volume and area are checked to SMLib's mass
property accuracy (2e-7 relative) instead of 1e-6 absolute.

Three expectations encoded the old truck planar booleans' incidental output;
each is replaced by the exact answer:
- a_base_trimmed_for_a_flange_keeps_its_arcs: the flat outline has 10 edges,
not 12. The flange's bend zone and panel meet in line, and the union of
the two is one line along each side (a region's boundary has no vertex in
the middle of a straight run). Lengths and areas are unchanged and still
checked to 1e-9.
- a_base_trimmed_through_a_free_form_curve_follows_it_with_arcs, renamed
..._keeps_it_exact: the trim cuts the parabola exactly, so the base keeps
one conic and three lines instead of tangent arcs within 0.001 mm. The
strip (183.564 = ∫ y from 197 to 200, or 600) and the bend's length
(62.364) are now checked to 1e-6 and 1e-9 instead of 0.22 and 2e-3; the
chorded comparison stays.
- pockets_with_free_form_outlines_are_machined_beside_free_form_cut_outs:
the machining record holds the pocket's four exact conics in their order,
started at another of them; the check is for the same closed loop, not
the same first segment.

Reading a planar sheet back from SMLib split each loop where two of its
segments started within ten times the record's tolerance (2e-5 mm), so
the two ends of an edge shorter than 2e-4 mm counted as one point and the
edge came out as a loop of its own, which the next planar boolean refused
("needs closed loops"). A loop passes a point twice where it passes one of
the record's vertices twice; the split now reads the vertices, not their
places. The sheet built from our own regions still splits by place, at ten
times the caller's tolerance.
Fixes sheet::tests::a_ledge_beside_an_edge_as_tall_as_the_setback_goes_with_the_strip

The SMLib planar sheet united every region's material and then cut every
region's holes from it, so a region lying in another's hole (the island
inside a ring cut) was cut away with that hole. Each region is now its own

Two tests rebuilt the old kernel's raw strips (a shell's wall split along its
opening, a stepped tab's -x wall split by the Join and the Cut) with today's
kernel and took the saved piece's name and projection from them. SMLib leaves
those walls one face, so there is no strip to rebuild: the tests now say so (the
wall is one face) and give the saved link as what an older file holds, its piece
name and its rectangle (y 10..20 x z 0..20 on the -x wall, the same 4-line
projection the strip had), and keep every check of what the model does with it.

The SMLib port of shell dropped with_shell_planar_sources (then deleted it as dead
code), so a shelled body's kept walls and their inner linings had no ShellPlanar
certificate: a sketch or press-pull on a shell's floor lost its attachment (the Pi
case's Sketch2 and everything after it, press_pull_on_the_pi_case_floor) and the
shell certificate tests found no inner/outer face. The roles come from the input's
exact planar supports, so they apply to SMLib's result unchanged.

Mesh::ray_crossings and InsideIndex counted a triangle crossed by a
Möller-Trumbore test with half-open barycentric bounds (u in [0, 1), u + v < 1).
Those bounds depend on each triangle's own vertex order, so on an edge two
triangles share the ray was in both or in neither: the bracket example's hole
centre lies on a diagonal of the base's top triangulation and was counted 0 or 2
times instead of once (bracket_example_cuts_two_through_holes_and_reopens).
Both now use ray_crosses, a watertight test: each edge's side of the ray is the
signed volume dir · ((p - o) × (q - o)), which is exactly antisymmetric in
floating point, so the two triangles of an edge see it with opposite signs, and a
ray exactly on an edge's line is put on one side by the edge's endpoints in
lexicographic order. New geom test ray_crossings_count_a_shared_edge_once crosses
a grid at every inner edge, straight down and obliquely.

The seeded robustness goldens (tests/robustness/goldens.json, tests::robustness_goldens) recorded
what truck built for seeds 0-95, so they now fail on every seed SMLib builds differently. The

each carry their own right answer, supersedes them.
Gone with them: fuzz::golden, the CI goldens lane (the goldens output, SLOW_SEEDS, the re-record

test-data mapping in affected.py. The robustness seeds and tests::robustness stay. The docs point

tess.wgsl sized its basis arrays for degree 7 by hand. It now holds 17 slots, degree 16 as the

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A G4 blend curve is one Bezier of degree 9, and the face extruded from it a spline surface of
degree (9, 1). The record accepts splines up to degree 16 (Brep::validate), but the evaluators
behind pcurves, tessellation and Continuity Analysis capped the degree at 7
(MAX_SPLINE_DEGREE), so the SMLib export refused the face with "pcurve: not supported yet: a
spline surface of degree (9, 1)". The cap was not an algorithmic limit: every routine under it
is the general NURBS Book algorithm, sized by fixed arrays of MAX_SPLINE_DEGREE + 1 slots.
MAX_SPLINE_DEGREE is now the record's own bound, 16, and Brep::validate reads the same
constant. The display evaluator's first-derivative basis (tess::basis_ders) works on two
one-dimensional tables (A2.2 at degree p and p - 1, eq. 2.7) instead of a square one, as its
GPU twin does, so the larger bound costs a low-degree surface nothing.

New: an r5 curvature corner at a box corner (its patch must seam G2), an

subtraction: V = 7139.875, A = 2585.140). The bar and boss arc rounded
together say their crease (15.6 deg r2, 13.1 deg r1); 1390 expects SMLib's

A new `continuity` area: seams whose order is certain by construction, each graded
`exact` (reads its order and not the next) at picked edges with Continuity Analysis's
default stations and tolerances: a box's crease (g0), a chamfer in place of a round (g0),
an r5 round on planes (g1), and a profile closed by a g1, g2, g3 or g4 blend curve between
lines, extruded (g1 … g4). `continuity.edges` may now be a list of points, picked as
`inspect.continuity` picks them, and `continuity.exact` asks for the order and no more.

expected.json may give `continuity: {order: g0…g4, edges?: "blend" | "corner"}`: the
seams of each round, chamfer face or corner patch with the faces either side of the edge it
replaced, and of each corner patch with its rounds, are measured as Continuity Analysis
measures them (seam_diagnostics at its default 33 stations and default tolerances), and the
case fails naming the worst seam, its faces, the order it reaches and the next order's worst
value. The seams come from the faces' persistent names (doc::naming::blend_seams). The older
`{near, within_mm, …}` form is kept.
Every fillet-area case with a body gets its order: constant rounds and rolling corners g1,
curvature rounds g2, chamfers g0, the corner: g2 patch g2 at its seams.

A torus face covering most of its tube off the tube's quarter lines (an
exhaust collector's bend: 326° of the tube from −113.8°) needed a fifth
quarter along the tube, which STEP counts from the outer equator: its form
ran past a full turn of the tube and SMLib refused the solid. #8496 turns
frames about the axis only, and the torus label had no tube reference.
The torus label gets a tube start (`tube_start`, radians; 0 and left out
of the record by default, so older records mean what they did): v counts
from there, in every evaluator, form, pcurve, iso curve, tessellation,
placement, SSI and SMLib transfer. A spilling torus face's tube start moves
to where its tube begins, or a turn before where it ends, whichever puts
its tube circles on the grid of a round face they are about the axis of
(a pipe's cylinder meeting the bend); circles round the tube are labelled
from the tube start (brep::form::on_tube), so their forms and pcurves lie
on the face's quarter grid exactly. The saved-format change is one file,
crates/doc/src/format/pending/torus-tube-start.rs.

An app that embeds the engine can install a check on the Session

uv::closed tells a spline closed on itself (periodic, one knot interval per period) by
its first and last control rows and knots clamped at both ends, checked as k[0..=p] and
k[n..=n+p] all equal. Over its interval [k[p], k[n]] a spline of degree p never uses
k[0] or k[n+p]: it starts at its first control point and ends at its last when
k[1..=p] and k[n..n+p-1] repeat. A periodic quadratic circle written with knot
multiplicities 1,2,...,2,1 (as OpenCascade writes one) was taken as open, so its seam
edge's two uses got one pcurve and the face was refused as a loop across a closed
spline surface's seam without a seam edge (periodic_knot_tube_faces_import_and_mesh:
"pcurves failed on 2 of 2 faces"). The check now skips the outermost knots; the knots
the existing test calls unclamped (uniform) stay open.

A SPHERICAL_SURFACE face bounded by one meridian used both ways is a whole ball, but the
file's placement need not have its poles at the meridian's ends: a sphere's frame is any
right-handed frame about its centre (the same surface, its natural normal outward). With
the poles elsewhere, the seam is a slit across the face's form, not the form's own seam;
SMLib's export refused the record ("a closed shell bounds two regions and encloses one"),
and the ball was not imported
(seam_only_sphere_whose_placement_axis_misses_its_poles_imports_as_a_whole_ball).
Before anything is measured on the frame, such a sphere's frame is put on its seam: the
axis through the seam's ends (which must be antipodes on the sphere, within the
tolerances), the x axis through the seam's middle. A seam already between the frame's
poles keeps the file's frame.

A cylinder, cone, sphere or torus face of one whole turn has a NURBS form of the four
quarters from the one its seam starts in (brep::form::face_quarters). When the seam is
not on a quarter line of the file's frame, the seam's second use lies a period on, past
the form's end: the face's domain stopped at the form's end and SMLib measured a ball
whose seam meridian is 0.7 rad off its frame's x axis 2.2% short
(tilted_seam_only_sphere_imports_as_a_whole_ball: 32.03 vs 32.74 mm3), and a 5 mm ball
with its seam 1 rad off, holding a 2 mm void, 481.0 vs 490.1
(seam_only_sphere_void_is_turned_inside_out).
turn_quarters, which says whether turn_frames (ee4d4b5a5) turns a face's frame, counted
such a whole turn as four quarters, never a spill. It now counts the quarters the face's
angle interval needs on the grid (brep::form::quarters, as for a face of less than a
turn): five for a whole turn off the quarter lines, so the frame is turned about its
axis to put the seam on one, and the form's seam is the face's.

The schema 4 reader adds a seam to a face that winds around its surface without one
(3d7e465b1) and turns over a face whose loop disagrees with its same_sense, and notes
both (the spindle torus tests assert the seam note). The tests written against truck
expected no warnings:
- step_conformance_parts_read_back_their_exact_shape: each part's seam count (the cone,
dome, cylinder parts bounded by their rims alone); volumes, boxes, faces unchanged.
- extruded_ellipse_patch_crossing_profile_seam_stays_trimmed: same_sense .F. adds the
turned-over note.
- implicit_bound_can_still_describe_the_complement_of_a_patch becomes
implicit_bound_against_its_face_sense_turns_the_face_over: the strip's one bound on a
cylinder cannot be a hole (the cylinder is unbounded along its axis, so the face would
have no outer boundary); the loop bounds the face, turned over, the 42 mm2 strip.

The face-bounds limit lives in crates/step's topology (MAX_BOUNDS, 54b10b9a3) since the

The reader (crates/step, f06581ca5) keeps distinct knots and their multiplicities and
never expands them; a multiplicity above degree + 1 is invalid (ISO 10303-42) and is
refused on its own as 'bad knot multiplicity' before the sum is compared. The test's
1,000,000 knots of multiplicity 64 on a degree-1 curve hit that first. Both checks are

unsupported_face_is_left_out_and_reported replaced a plane with an OFFSET_SURFACE on a

CURVE_BOUNDED_SURFACE, which the reader does not read. Since cfee4a720 and 4cb0d6ee9 a

An edge that lies off its face's surface has its tolerance raised to cover the
gap before SMLib makes its trims (cover_gaps). Where such an edge runs out of
its patch, SMLib ends it where its drop onto the patch ends when that is within
the edge's cross-section tolerance of its vertex (SmEdgeuse::CreateUVTrimCurve),
and moves the edge's interval there. The moved end was checked against the
edge's tolerance before it was raised (1e-5 mm), so two faces of Poppy
Humanoid's left thigh, whose edges SMLib ended 0.08-0.1 um short with a held
tolerance of 0.77 um, were refused ("SMLib moved an edge's interval"). The end

Each body a section cuts is hatched at 45 or 135 degrees in one of three
colours of one family (the cap's clay, a steel and a sage, theme tokens
`section_cap` and `section_hatch`). Bodies whose cut outlines touch or
overlap get different hatches, the angle changed first, then the colour
(solidcraft_render::hatch, a greedy map colouring of the cut); otherwise a
body keeps the hatch its name seeds, so it stays the same from frame to
frame and as the plane moves. Spacing and line width are unchanged.

Ten `refused` cases outside the fillets had no `refusal` since #8445 made one required. Each
was run; its refusal is the right answer for the reason its method gives, and that reason is
now its `refusal`.

A cylinder, cone, sphere or torus face of less than one turn that does not
start on a quarter line of its frame, with more than three quarters left to
it, spilled into a fifth quarter of the quarter grid: its NURBS form ran past
one turn and SMLib refused the solid ("an edge lies 12-16 mm off the face's
surface"), which came in as surfaces.
Before its edges are labelled on it, such a face's frame is turned about its
own axis (brep::form::turned: the same surface, its angle parameter measured
from further on) so it starts on a quarter line and its form spans four
quarters. Round faces a circle edge about both their axes joins share one
quarter grid, so they turn together by one angle, chosen so every one of them
fits in four quarters; a group with a face that cannot be turned keeps the
file's frames. Each face's box on its label is measured once and reused.
Engine assembly: PULLEY_WATER_PUMP and MOUNT_SCAVENGE_PUMP_01 now come in as
solids (refused 5 -> 3); Poppy Humanoid unchanged (4).

A body showing another's display (a later instance of a part an assembly
places several times) took that part's mesh, placed, but was planned for
the GPU viewport on its own: Poppy Humanoid's display planned all 247
bodies where its meshes came from 94 parts. Body::mesh_plan now plans the
original once (kept with the shared display, as its meshes are) and moves
the plan, so the copy's display is the part's triangulation, as its mesh
is. Body::unmeshed_faces needs no case of its own for a copy any more.

The STEP import's mesh check made a coarse mesh of every part (planned,
evaluated, its seams and smooth edges flagged) only to see which faces had
triangles, and threw it away. A face has triangles in the evaluated mesh
exactly where its plan has a triangle on its own nodes, so the count is now
read off the plan (TessPlan::faces_with_triangles, the condition evaluate
keeps a triangle by).

A window of planned solids ended at the second instance of a part not yet
read, so an assembly that places a part several times in a row converted
in windows of one or two solids, each waiting for its slowest read before
the next began (Poppy Humanoid: 14 windows of 1 to 30 reads on 8 workers).
The window now always takes MAX_WINDOW solids; an instance of a part an
earlier job of the window reads is placed after that job, from the
orientation it found, as the next window would have placed it.

While a feature dialog says that a part's face can't be used for modelling, and while the
pointer is over that part's "needs repair" row in the browser, the face is outlined round its
edges in the theme's error colour, over the shading and dimmed where the model hides it, like
the selection's outline; it goes when the message or the hover does. Show face now frames the
face without selecting it (a selection in a dialog becomes its pick and cleared the message).

SMLib's import says only that it refuses a body, so the kernel now keeps a structured
refusal with the body's SMLib cache (Body::smlib_refusal / smlib_refused: the first face SMLib
refuses on its own, found by sending each face alone, and its surface kind). A STEP import sends
each part's first instance as an operation would, notes the parts that need repair in the
import report, and the browser marks them ("VALVE_COVER_01: needs repair").
A feature dialog whose operation fails on such a part says, instead of the kernel's words and
an issue report: "Couldn't join to VALVE_COVER_01. One of its rounded faces can't be used for
modelling.", with Repair part (body.repair, declared as planned, also in the part's menu) and
Show face (selects and frames the face).

The kernel's import warnings get a structure (ImportReport: the file's parts, how many came
in as solids, and each warning's kind, part, faces and count; the reads' notes are typed as
repairs or faces left out). The Import feature's result carries it (and the model cache keeps
it), and the timeline tooltip and the status line after an import word it from the catalogs:
"Imported 40 of 43 parts as solids. 1 part couldn't be made into a solid and is shown as a
mesh. 3 faces couldn't be repaired and are missing." with what may help. Entity numbers and
the kernel's wording stay in Copy Warning Message, which now lists every warning.

An open or an import lists its three steps (a STEP or IGES file: reading the file, checking

text and how far it is, and the bar for that step. The other file operations keep their one

The Setback field's "More than 2 mm" is the message; the kernel's refusal of

The Setback field reached the command and the kernel used it: on a box corner
with r 2 rounds a 3 mm setback built, while 1.5 and 2 mm failed inside SMLib
(status 1001), shown as "could not be built" with nothing saying why. A setback
must reach past where the rounds meet without one (the radius on square faces).
The kernel now refuses such a setback before SMLib runs, naming the least
(the pre-check of aa2b09bc2 on fillet-kernel-cases), and exposes that least
(fillet_least_setback). The field shows the default, 1.5 x the radius, as an
editable length that follows the radius until the user types one, and outlines
a value at or below the least in the warning colour with "More than 2 mm"
under it (ui_kit::checked_row, warning_caption). Its hover text says what a
setback does, the default and the least.

An open body (a surface body, a mesh that does not close) has no inside: its faces counted
with the rest took the cap from the closed body it lay in or behind. The body's closedness,
which the kernel knows (`ModelBody::is_closed`: no shell left open, a mesh body every side of
which two triangles share), goes with it to the renderer (`SceneMesh`, `PlannedBody`,
`InstancedMesh`, a block's closed runs, the loose open triangles), and the count draws closed
bodies only.

The cap went to the nearer surface by depth: a back face (the cut body's far wall) or a front
face. Where bodies touch, the cut body's far wall and the other body's face lie at one depth,
and rounding settled each pixel either way: the other body showed through the cap in specks,
stripes and triangles (an engine's sleeves in their bores, pins in their bosses). The stencil
now counts the faces behind the plane instead, from a base of 128: a back face adds one, a
front face takes one away; above the base, the plane is inside a body and the cap is drawn in
the nearest back face's cut colour, at the plane's depth. Elsewhere the faces draw as without
a section, an open body's inside lit rather than hatched. All four draw paths (built, planned,
instanced, instanced flat).

A face's form covers the quarters of its box, and the box is the extent of its
boundary's points, which run past a quarter's end by as much as the edges lie
off the surface (nanometres in a file of 1e-11 mm digits). A half tube's form
then took the quarter past each end and went round the whole tube, which SMLib
does not take for a torus: 16 parts of an alternator came in as meshes. An end
within the tolerance of a quarter's end (the angle on the face's widest circle
there) is now on it.

A corner setback must reach past where the corner's rounds' contact lines
meet without one (smlib_blend_setback); short of it SMLib failed with its
own status (1001). The kernel now refuses it before SMLib runs, for the
rolling-ball corner (fillet_setback) and the curvature corner
(fillet_g2_corners) alike, naming the least: on each face at a corner of
planar faces and straight edges the two rails, r tan(psi/2) from their
edges, cross (d2 + d1 cos alpha) / sin alpha along an edge (r on faces
square to each other). Other corners stay SMLib's to refuse.
The rig's `refused` cases now name the reason (`refusal`, a part of the
message, required), so a failure for another reason no longer passes; a
`solid_or_refused` case may name one. Fillets: the setback cases and
783, 3435 pass; 1390, 896, 4782 past-a-full-round and the no-tangent-chain
case are refused for an unclear reason and fail.

22 hand-written cases in tests/kernel-cases/fillets:

fit taper, curvature corners): a bar's top edge and the partial base
arc of a boss standing out over the bar's side rounded together. The
rounds' volumes away from the corner, the corner patch within (2r)^3.
SMLib's 3x2 mixed corner fails here (1001) until the fork's fix.
- 1207-fillet-bar-top-edge-after-boss-arc-round (r2, r0.5, no tangent
chain): the edge rounded after the arc; r0.5 fails SMLib's check.

curvature corners), the curvature corner at r1, and the curvature
corner with reduce and taper fits (not supported yet).
- 4782-fillet-*: full rounds (two end verticals at half the width, exact,
reduce, taper), a round at half the wall, radii past the full round
(refused; reduce gives the full round) and a round wider than both
faces (built by subtraction).

The old body was drawn as ghost whole, behind the new body by a fixed depth bias. A curved
face the change re-meshes (a boss face whose boundary a fillet moves) has a new triangulation
that crosses the old one by up to the chord error, far past that bias, so the ghost showed
through it in slivers. Old triangles lying on the new body's surface are now left out; the
removed material is still shown.

The held parameter was spaced over each face's own trimmed (u, v) box, so the pieces of a
face split by a boss showed different lines that missed each other at the split. The lines
now sit on a ladder of the surface: a bounded parameter's range in count + 1 steps, a linear
one (a plane's, a cylinder's or cone's axis) at a round world spacing from the world origin.

The dialog follows the options solid.fillet takes together: If too large
(fit) and Corners show only for Constant radius, a curvature corner and a
fitted radius rule each other out and the other resets visibly, and an
option that does not apply is never sent (it used to send `corner: g2`

SMLib holds both sides of a sheet's faces and gives each back on its surface's
natural side, so a sheet whose file uses faces the other way came back
renumbered. The reader no longer turns them (that lost the file's side);

A solid the reader or SMLib refuses was shown as a mesh of its faces (#8223):
exactness lost, cracks between faces, and no modelling. It now comes in as an
open surface body of the faces that read, sharing their edges as the file has
them; each face left out is named.
- The reader reads a solid with a set of faces left out (read_solid_without):
a sheet whose faces face their surfaces' natural normals, as SMLib gives a
sheet's faces back, so SMLib's body numbers the faces as the record does.
- Tier 1: the faces that cannot be read alone and the face each refusal names
(named_face) are left out, up to 8 reads. Tier 2, when a refusal names no
face of the solid: the one-face bodies stitched by SMLib. Tier 3, when SMLib
cannot stitch them: the mesh of them, as before.
- Report: "imported as surfaces: <why>" and "left out: face #..."; the
ImportedBody field shown_as_mesh is now refused.

A face's boundary node on a patch side collapsed to within the tolerance of
the vertex there (capped at the chord tolerance), not to a point, is a pole:
its parameter along the collapsed direction is free, as the record check and
the STEP loop check take it (`uv::collapsed`, shared with
`SurfaceEval::pole_within`). A loop through such a corner no longer winds
round the surface as projected, and plans strictly (Poppy Humanoid's
connector, face 43: a quarter of a sphere cap on a closed rational spline).
A face the strict plan and the lenient fill both refuse no longer fails the
whole body's mesh: it is left out with no triangles, named in
PlanStats::unmeshed (logged by the display plan, counted by
Body::unmeshed_faces), and the rest of the body is meshed; a body none of
whose faces plan is still the first face's error. Body::volume_at gives no
volume for a mesh with a face left out.

When the reader or SMLib refuses a solid, each of its faces is read on its
own as a one-face surface body (solidcraft_step::topology::read_faces_with)
and meshed by the planner; the triangles together are a mesh body (the
existing kind STL/3MF imports make), marked ImportedBody::shown_as_mesh with
the refusal. The report says 'shown as a mesh: <reason>' and names each face
left out. Modelling operations refuse it as any mesh body.

The check that a loop does not jump across a spline surface's parameters took a
pole only within the face's tolerance. A corner patch written with one side
shrunk to a few µm (Poppy Humanoid's connectors: 5 µm in a 1e-5 mm file) was
refused, though the record check takes the same junction as a pole at the
tolerance of the vertex the uses meet at. The import check now uses that
vertex's tolerance; the loop runs along the collapsed side, its boundary iso
line. A jump that is still refused says whether the surface closes there.

An edge whose curve runs a few um past its vertex and its spline face's
patch was trimmed back by SMLib when it made the trim, and the face was
refused ("SMLib moved an edge's interval"). Our own measure never saw the
gap: STEP measures an edge against its surface only where the nearest point
is in closed form, and a spline face's gaps only on the pcurves the kernel
returns, after SMLib has trimmed the edge. Each bare use's edge is now
measured by SMLib (smlib_brep_edge_face_distance, over the patch) after the
sheet's import, its tolerance raised to cover the gap with
SURFACE_GAP_MARGIN and the sheet imported again: SMLib keeps the edge whole.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
An edge raised to cover its pcurves' gap could get past SMLib's limit
(Congé19: 0.98 mm off, tolerance 1.47 mm) and its whole solid then failed
as "SMLib rejected the input". The tolerance an edge or vertex would get,
not only its gap, is now held to that 1 mm: farther off is refused with
how far. The record mapping refuses a tolerance past it with a message
rather than handing SMLib what it rejects.
The margin over a surface gap moves to solidcraft_geom::brep::pcurve
(SURFACE_GAP_MARGIN) for SMLib's pcurves to use too.

The analysis sliced the display mesh with planes: faceted, approximate, and
broken at triangle seams and trims; the window drew it as a 2D overlay without
depth while the tool was active. Now one kernel routine (kernel::iso) clips a
surface's u = const or v = const line to a face's pcurve loops; the curve through
a point (sketch projection) and the analysis grid (count each way, evenly across
the face's extent) both use it. The loop polygon follows the loop's order (a
pcurve the loop runs against is walked backwards), which the inside test got
wrong before, and closes over vertex-loop poles.
ModelBody caches the lines per face, count and display quality. The session
keeps the picked faces as view state (inspect.isocurve add/clear, hostile counts

The nearest point on a spline (5cb015fae measured spline faces up front too) may settle on
another part of the surface, or on its boundary for a point a hair past it, and reported gaps
the edges do not have: 2.9 mm on Poppy Humanoid's leg shells, whose edges lie within 0.003 mm
of their faces, and widened tolerances past what SMLib takes (it then refused
models/vertices-off-curves.step). The up-front measure is again for faces whose nearest point
is in closed form (plane, cylinder, cone, sphere, torus); a spline face's gaps are measured
on the pcurves its kernel makes, as the record check measures them.

Two edges leaving a vertex almost tangentially (a cusp, as a round runs out on Poppy
Humanoid's creative_commons_license) separate by about Δκ·s²/2 at distance s while a chord of
length L sags by κL²/8: halving the chords never stops them crossing. untangle returned that
face's error for the whole plan, and the body's 1834 faces were not shown. It now returns the
faces still crossing, each with why, and plan_or_fill fills each leniently straight away and
names it in the stats (the rule of #7755): the other faces are planned as usual.
Test: a face named as still tangled is filled leniently and named with that reason.

A corner ball's edge may run from its equator over the sphere's pole to a vertex just past
it (Poppy Humanoid's creative_commons_license: 1.8° past, 0.016 mm off the pole). On the
sphere's parameters the pole is a line, and the edge's pcurve would have to jump half a turn
along it: "pcurve starts 2 from the end of the use before it, on another period". Each
edge that passes through a pole of a face it bounds (a sphere's, a revolved face's on its
axis) inside its interval is now split at the nearest point to the pole (golden-section
search from 16 samples), the new vertex placed on the pole; the loop's half turn is then at
a vertex on the pole, where a loop may run along it. Each solid's notes say how many edges
were split. The geometry check takes a vertex at a pole to within the vertex's tolerance, as
the reader already does (SurfaceEval::pole_within).
Without the split the edge's jump read as a 0.024 mm gap and was covered by a tolerance:
the measured gap now only covers what the file's geometry really has.
Test: a spherical triangle (radius 0.5) with an edge over the pole to 1.8° past it reads
with its spherical-excess area and its edge split.

A range sampled in even steps ends at a + (b − a)·1, which may round one ulp past b, where
find_span gave no span and every B-spline evaluation there failed. The import's loop area

it: "outer loop runs clockwise in (u, v)" on 7 of Poppy Humanoid's solids. The same step

SMLib may end an edge at a parameter of its own: a knot its vertex lies at (-1.0 where the
vertex's angle gives -0.99999998, a 2e-8 step on the edge's quarter arc, far under 1e-6 mm).
We refused any change beyond 1e-9 of the parameter, a bound with no geometric meaning:
"SMLib moved an edge's interval" on 8 of Poppy Humanoid's faces. The ends SMLib chose are now
measured on the edge's curve: within the edge's tolerance, its pcurve is mapped onto our
interval by the affine change of parameter (exact for a B-spline: its knots move), and the
record's check measures it as any pcurve; farther is SMLib trimming the edge, refused with
how far.
Poppy: 227 → 232 bodies, 17 → 15 solids not imported, no interval refusals left.

When an edge's tolerance is raised to the gap it has, the vertices at its ends now cover it
too, as in any tolerant record (SMLib takes the vertex's zone as at least its edges'). The
edge measures sample the interval's end as t1 itself: t0 + (t1 − t0)·1 may round past it.
(This commit also measured spline faces up front by nearest point; 04de97cd9 takes that out.)

The closed-form pcurve's lift check sampled t0 + (t1 − t0)·k/n, which at k = n can round
one step past t1 (1.2985843833752289 for an end of 1.2985843833752286), where the pcurve
on [t0, t1] has no point: the closed form was refused, and on a plane, which has no
parameter box for a kernel's pcurves, the face with it ("a face on an unbounded surface
without closed-form pcurves", Poppy Humanoid's Combine1 and others). The end is now t1.

Brep::validate lets a pcurve's interval differ from its edge's by PCURVE_INTERVAL (1e-9

edge's own ends and samples, which may lie just past it: "the pcurve has no point at
2.0000000000082903" on four of Poppy Humanoid's solids, circle edges whose end vertex
sits on a quarter of their form, where SMLib's pcurve ends on the knot. Both of the

A closed-form pcurve (a B-spline edge's control points projected onto its plane) is
accepted within half its edge's tolerance, and the edge carried the file's: Poppy
Humanoid has planes whose B-spline edges stand 9 µm off them in a file that states
10 µm. The closed form was refused, and a plane has no parameter box for SMLib to make
pcurves in: "a face on an unbounded surface without closed-form pcurves" on 11 of its
solids. On a plane, cylinder, cone, sphere or torus (nearest points in closed form)
each edge's distance from the surface is now measured along it first, and its
tolerance covers three times that; a spline face's gaps stay measured on its kernel's
pcurves, with the 1.5 × margin of a vertex's. The pcurve code reads each use's own
tolerance.
Poppy: 194 → 195 bodies, the unbounded-surface refusals 11 → 3 (the solids they let
through now stop at later steps); the corpus survey and the kernel tests are as before.

A TOROIDAL_SURFACE whose tube reaches its axis (major radius at most the minor, or
written with a negative major radius) and a DEGENERATE_TOROIDAL_SURFACE were refused.
They are read as what they are: the tube's meridian circle (centre C + R·X, its angle
from X towards Z) revolved about the axis, the same points and normal as ISO 10303-42's
formula, a negative R putting the tube's centre across the axis.
A revolved circle or ellipse that meets its axis is now its whole arc on the face's
side, pole to pole, in closed form (where s0 + M cos(t - phi) = 0), and its NURBS form
is cut there exactly (Boehm knot insertion, bspline::segment): the parameter stays the
quarter grid's, so the edges' forms and straight pcurves are unchanged, and the surface
ends at the poles instead of running on to whole quarters past the axis (which folded
the surface over itself, and left a face with one bound around the axis without its
pole). The face's boundary picks the apple or the lemon.
On Poppy Humanoid 22 solids were refused for these tori; with the SMLib fixes before
this none of their torus faces fails: Poppy 42 -> 27 solids not imported, 194 -> 215
bodies.
Tests (hand-written files, analytic answers): a horn torus round of radius 1 on a pin
(V = 8 pi + pi(5/3 + pi/2)); a spindle torus pin end (major 1, minor 2, its apex in a
dimple at z = sqrt 3, V = 3 sqrt3 pi + 8 pi^2/3 on the cylinder) as TOROIDAL and
DEGENERATE_TOROIDAL, with a seam to the pole and with one bound; a nearly round end
(0.005 / 0.345) in two halves with SolidWorks's apex vertex; the lemon of a spindle torus
as one seam-bounded face with major radius -1 and as a degenerate torus with its lemon
selected (V = pi(6 sqrt3 - 8 pi/3)). Volumes and areas within 1e-3.

The pcurves close a face's loop through a pole to within the face's tolerance (a
point where crossing half a period moves less than that): there the periodic parameter
is free and the loop jumps across. The reader's check that no loop crosses a seam
without a seam edge took a pole only exactly (1e-9 relative), so it refused the loops
the pcurves had closed near one. Poppy Humanoid's nearly round pin ends (a spindle
torus of major radius 0.005, minor 0.345) have their apex vertex at the tube's top,
3.6e-5 mm above the true pole: their meridians end 1.7e-6 rad short of it, and 13
faces were refused. Both now use one test, SurfaceEval::pole_within.

A revolved circle whose centre is as far from the axis as its radius (a horn torus, its
tube touching the axis) measured its major radius a few ulps above its minor from the
profile's control points, became SMLib's ring torus, and SMLib refused it
(SM_ERR_INVALID_INPUT: no ring torus of that NURBS). A ring torus now needs its tube
clear of the axis by more than rounding (1e-9 of the radius, the slack the same test
already takes for the circle's plane); a horn torus goes as its rational B-spline.
Test: a revolved unit circle 1.5 from the axis is a ring torus; at 1, 1 + 4 ulp and 0.5
it stays a revolution (develop calls the first two ring tori).

A face on a placed revolution that carries its NURBS form (every STEP surface of
revolution, read since b6a3b31ff) was written as two NURBS blocks: the revolution's own
net, then the form, flagged FACE_NURBS_FORM on a NURBS face. SMLib reads one block per
face, so the flat arrays did not add up and it refused the body (SM_ERR_INVALID_INPUT),
in the main import and in the one-face sheets SMLib makes pcurves on. SMLib has no class
for a revolution: the form is the face, its range and trims already in its parameters,
so it now goes as that NURBS face with no form flag. A revolution the analytic pass
recognises (a plane, cylinder, cone, sphere, ring torus) is unchanged.
Test: surface_of_revolution_sense_follows_iso, which develop fails with the refusal,

Each edge is sampled on its own, and a short one within the chord tolerance is one
segment. A face bounded by two such edges (a lens of short arcs, a sliver strip of a
cylinder between two rulings) had two chords on one line: "degenerate boundary", and
the whole body's display mesh failed with it (one of Poppy Humanoid's bodies lost all
336 faces to one sliver). Such a loop's segments are now halved until it has three; the
new nodes are on the edges' curves and shared by every face that runs them.
Test: a lens of two radius-1000 arcs beside a 2 m face meshes; without the split it
fails with the same error.

An edge's curve as a file writes it may lie off a face's surface by more than the
file's stated uncertainty: Poppy Humanoid's intersection curves lie up to 9 µm off
surfaces in a file that states 0.01 µm, and 24 of its solids were refused by the
record check ("pcurve … lifts off its edge's curve"). Each use's gap, between its
pcurve on the surface and its edge's curve, is now measured along the edge at 17
points as the record check measures it, and the edge's tolerance covers it (1.5 ×
the gap, as a vertex's covers its gap; more than 1 mm is refused). The pcurves are as
made, and each solid's notes say how many edges were raised and how far.
The pcurve fit's tenfold retries went in 6cc0401fa; this measures instead of
retrying. On the corpus (the repository's STEP/IGES files, the models repository,
Poppy): 50 → 53 of 56 files import; Poppy 132 → 194 bodies.
Test: a hand-written domed patch whose edges are written 0.2 µm above it (SMLib makes
its pcurves) imports with them covered; 1.5 mm off is refused.

New metric tapped holes drill the tap maker's drill (M8 6.8 mm). The Design preference "Metric
tapped holes drill the major diameter less the pitch" (`metric_tap_drill_major_less_pitch`, off
by default) gives them the drill every metric size took before (M8 6.75 mm): the Hole dialog
shows and sends it, and `solid.hole` given a thread and no `diameter` drills it, through the
session as `auto_project` is (kept when a design is opened or started, and across tabs). Unified,
pipe and taper sizes keep their tabulated drills; a given diameter is unchanged. Saved designs

Every tapped hole now drills the tap maker's tabulated drill. ISO metric takes Yamawa YEU23's
drill size column for cutting taps (printed p.704, M coarse; pp.704 to 706, MF fine): M8 drills
6.8 mm and M12 10.3 mm, where the major less the pitch gave 6.75 and 10.25. A custom metric size
the table lacks keeps the major less the pitch. UNC/UNF (Guhring), G, Rp, Rc and NPT (Yamawa)
were tabulated already. The Thread command's suggested hole for a metric size follows.
The Hole dialog's Tap drill diameter is now a field, the tap maker's drill by default, and the
command's `diameter` with a thread is checked the same way: a drill is accepted from the
internal thread's standard minor diameter (or the tap maker's drill where that lies below it:
Rp, Rc, NPT) to 5% over the tap maker's drill. Outside that the command names the range and
why. The field's tooltip gives the drill, the minor diameter and the range. Presets keep a
chosen drill.
A saved design keeps the diameter it stored, so it builds as before, and editing such a hole
keeps its drill: no preference and no format change. Scripts that give a thread without a
diameter drill the new default; ladder 05/007, 11/003 and rig case threads/2115 follow
analytically, and their golden entries are re-measured from runs (tier 05 re-sorted by time).

The Rc and NPT drills were rounded to a drill series from a third-party reproduction of DIN 345
and a fractional/letter inch series cited from memory. They now come from the same tap maker's
catalogue the G and Rp drills do: Yamawa YEU23, printed p.709 (Rc, the maximum straight bored
hole with non-full threads, Rc 1/16 to 4) and p.710 (NPT, the maximum straight bored hole, 1/16
to 3). A size its tables lack (Rc 5 and 6, NPT 3 1/2 to 12) is refused as a tapped hole, naming
the range. The dialog's tooltip keeps the standard's minor diameter where the thread ends.
Rc 1/2 drills 17.6 mm (minor 17.807), 1/2 NPT 17.60 mm (minor 17.473).

An Rc or NPT hole was drilled to the exact minor diameter where the thread ends, a size no shop
stocks. It now takes the largest stocked drill not larger than that: metric drills of the DIN 345
series for Rc (to 100 mm), letter and fractional inch drills by 64ths (to 1 1/2 in, ASME B94.11M)
for NPT; past the series it is bored to the exact value. The Hole dialog's drill shows the inch
size for NPT, and its tooltip the exact standard value. Rc 1/2: 17.807 mm, drilled 17.75 mm;

The tapped-hole catalogue takes ISO 7-1's Rc and ASME B1.20.1's NPT internal taper threads,
every size of the tables a modelled thread cuts. Their drill is the internal minor diameter where
the thread ends (the reference plane's minor at the face less the 1 in 16 taper over the useful
or effective thread length), derived from the standards rather than a tap maker's table. An
external R is still no hole's.
A tapped hole's options mirror the thread's: `modeled` cuts its thread into the wall, from the
entry, by the same cut as `solid.thread` (now one function both call), and `ease_out` fades its
inner end out before the bottom (ISO 3508); without it the groove stops square at the thread
depth, clear of a blind hole's bottom. The Hole dialog's Tapped rows add Rc and NPT, Modeled
and the End choice (Square, Fade, Fade Length). The format notes in pending/thread-ends.rs and
pending/pipe-threads.rs record the new keys and sizes.

The thread dialog offers the pipe threads: G (ISO 228-1), Rp (ISO 7-1), R and Rc (ISO 7-1) and
NPT (ASME B1.20.1). Their sizes are listed by designation without a pitch, one start and a hand
of right or left; a size picked for a hole the dialog sized Rc stays Rc.
Rp, ISO 7-1's parallel internal thread an R screws into, is a form of its own (`rp`): the
parallel profile (H = 0.960491 P) at ISO 7-1's gauge diameters, refused on a shaft. Its cut
meets the analytic material of its profile within 1e-5, as G does.
A taper thread takes a chamfered tip: each end's cone is measured from the major diameter the
taper has at that end. Pipe threads are not ISO metric, so they give chamfer_depth.

The thread's start is its free end: it runs off plain or chamfered (ISO 4753). Its inner end
stops square in its own profile or fades over a length; an empty Fade Length is ISO 3508's
runout (2.5 P, or 1.25 P for a thread saved short). A thread saved chamfered at both ends keeps
that. "Square" is its own message (thread.end_square), apart from the geometric square. The
new labels are in en, ar, he, ja, zh, de and ko; Extent, Ends, the chamfer labels and the ISO

A thread's start runs off its free end, plain or chamfered; only its inner end fades out
(ease_out) or stops square. The `ease_in` field, the command parameter (refused now, naming
ease_out), the dialog's Ease In row and their docs are removed; `pending/thread-ends.rs`

The free-end test looked for material 1 to 1.5 pitches past the face's end, beyond the first
pitch so that a chamfer the groove runs out through counts as free. A plate thinner than that
(a boss on a 1 mm plate under M10) had none there, so its top was taken for a free end and
the groove's one-pitch overrun cut into the plate (15 mm³ of a 1 mm plate).
An end is now closed when, over the overrun's whole reach, material lies outside the face's
cylinder (inside it, for a hole) at the radii the groove cuts beyond the face: a shoulder,
plate, head or blind bottom, however thin, steps out past the face, while a chamfer, neck,
countersink or counterbore steps the other way. The band test beyond the first pitch stays
for a cylinder that goes on past a split.
The regression test builds the boss as the app does (a rounded plate, a circle sketched on its
top face, extruded with Join) on 6 and 1 mm plates.

Three forms: `bspp` (G, ISO 228-1, 55° parallel), `bspt` (R external, Rc internal, ISO 7-1,
55° taper 1 in 16) and `npt` (ASME B1.20.1, 60° taper 1 in 16). Their sizes are tabulated
from the public sources: ISO 7-1:1978 Table 1 (its gauge-plane diameters are the G sizes)
and NBS Handbook H28 (1957) Table VII.2; tests check every row against the standards' own
relations.
A taper thread starts at its free end with its standard diameter there (external: the gauge
diameter its gauge length in, internal: at the face). Its groove is the screw sweep with the
section moved 1/32 of the axial travel off the axis (the radial law the runouts use, added to
it), its section reaching just past the crest, and the material beyond the major cone (or
inside the minor cone) is cut with it, as a die or tap cuts the crests. An external one runs
its standard length by default.
The volumes are checked against the profile's material fraction integrated over the tapered
radii: G 1/2 to 2e-6, R 1/2, Rc 1/2 and 1/2-14 NPT within 0.2 % of the cut.

`tip` was none|chamfer, chamfer cutting every free end. It is now none|start|both: `start`
chamfers the end the thread starts from, refused when that end is not free (a shoulder, or a
stop inside the face), and `both` every free end as `chamfer` did. The dialog's Tip pick offers
None, Start and Both; `tip: chamfer` in a command names its replacements.
The thread's end options (runouts, tip, chamfer angle and depth) came without a format

ISO 4753's chamfered end bounds the end's diameter by the minor diameter. The default took the
modelled root (the basic d1) for it, so the cone's small circle lay on the root cylinder and
the chamfer ring pinched to nothing wherever the groove reached the end. The default is now
the external minor diameter d3 = d - 1.226869 P of ISO 724, below d1: the cone crosses the
root, each end is a whole disk of d3 inside a whole conical ring. ISO 4753 is for ISO metric
threads; the other forms, whose root is already their design minor, give chamfer_depth.

A face whose boundary crosses itself in (u, v) (a cusp, a sliver whose sides
sag across each other) was an error, and the body had no display plan. It is
now planned once more with a lenient constrained Delaunay in (u, v): sides
crossing one already kept are left out, the rest is seeded and refined as any
face, and its points lie on the surface, where the GPU evaluates them. The
display has no hole, but the face is still a defect upstream, in its pcurves
or seams: PlanStats::lenient names it with the strict plan's refusal, and the
display plan logs a warning for each such face, so it is never silent.
The face boundaries keep coming from the exact pcurves (d61efb306); cdt::Fill
gets its `lenient` field back (dropped in 3f2585569). The old flat fill (#4021,
tess/fallback.rs) stays gone: develop removed it in 9138e8704. A face the
lenient fill refuses too (loops that do not close in (u, v), or wind round a
seam or pole) stays an error naming the face. Closes#4453's intent on develop.

SMLib's out_failed_corner reaches Rust as Error::CornerRefused { corner }, and the
kernel names the corner by its point: a G2 fillet at a corner of mixed convexity
says where it is and that SMLib sets back only corners whose rounds are all
convex or all concave. Engine test checks the message through solid.fillet.

The inner corner of a 20 x 20 x 10 notch in the 60 x 40 x 20 box, three
concave r5 rounds with corner: g2: one valid body of 13 faces within the box,
the patch's twelve seams jumping at most 1e-3 per mm clear of the hole's six
corners (2.7e-4 measured; the ball corner jumps 0.2). The continuity check
looks within 11 mm of the corner: the vertical round, 2.5 mm long past its
setback, meets its faces 11.2 mm out with every round's G1 jump.

The inner corner of a notch, three concave r5 rounds, takes the set-back G2
patch as a convex corner does: one valid solid with the ball corner's 13
faces, seam jump 6.3e-4 per mm clear of the hole's corners against the
ball's 0.2. A corner of two convex rounds and a concave one is refused as not
supported: SMLib sets back only corners of one convexity.

vertices where two of them turn, where a neighbour's own G1 seam ends.
07/015, the box corner's three r5 rounds with corner: g2: one valid body of 10

clear of the hole's six corners by 1.2 mm (2.7e-4 measured; the ball corner
of 009 jumps 0.2). Its golden entry is the passing run's.

FeatureKind::Fillet with corner G2 is kernel::fillet_g2_corners, its setbacks
the corners' distances (the rest 1.5 r); setbacks now go with either corner.
The engine's corner test builds the G2 corner, default and set back 7, one
closed solid of 10 faces within 0.1% of the ball corner's volume.

A corner where three or more rounded edges meet, every edge there rounded, is
set back (1.5 r unless a setback names it) and left open by SMLib
(blend_smlib::fillet_setback_open: the sheet and each corner's hole, in the
sheet's orders); each hole is filled by fill::matched_patch, the height field
over its plane fitted to the position, tangent plane and normal curvature
across the boundary of every face beside it (exact second derivatives), rounds
and planes alike, each edge's pcurve its exact projection; SMLib sews the
sheet and the patches into one solid, which must close. The history is the
sewing's carried through the sheet's, each patch face made from the rounded
edges its neighbours come from.
corner_g2 is that construction now. The polar patch over three sections it
held (never sewn in) could not be: its boundary is a closed cubic through
stations, which rounds off a corner of the loop, and the setback hole has six.
The 60 x 40 x 20 box corner of r5 rounds (07/015): 10 faces, a valid closed
solid (record and SMLib's check), curvature jump across the patch's seams
6.3e-4 per mm clear of the hole's corners against the ball's 0.2; set back 8
between the hull and prism bounds; set back 11 to 15 inside the box but by
under 7e-4; all eight corners of a box filled; refusals named.

smlib_blend_setback_open's binding: the sheet, and per corner a Hole, its
edges in order (each starting where the one before ends), each with the face
beside it and whether that face runs it forwards. The holes' buffer starts at
64 edges a corner and grows once to the length a first call names. Tested on

fill_loop's bicubic height field over the loop's plane, fitted to the
neighbours' derivatives as well as the loop: every condition of a graph is
linear in its heights (G1: the gradient from the face's normal; G2: the second
derivative along the face's leave direction from its normal curvature), so
one banded least-squares solve with the thin-plate energy decides the surface.
Its parameters stay plane coordinates, so an edge's pcurve is still the edge
projected onto the plane, exactly.
Where a round's section meets a plane at a corner of the loop, the section has
the round's curvature and the plane is flat across its own curve: no surface
is G2 to both there. The G2 rows fade in over 15% of the run from each corner;
asked over a few cells instead, the plane's flatness to the second order along
its curve pulls the surface off the whole side. Grids go to 128 spans, which
G2 to a plane along a curved line needs. The thin-plate weight is a thousand
times fill_loop's: with the slope and curvature rows acting a little inside
the loop, the weaker one let the surface rise past a plane it is G2 to (0.06
mm at a box corner of r5 rounds set back 8).
loop_frame is fit_once's plane, shared.
Tests: the hole a setback leaves at a box corner of r5 rounds set back 8,
within 2.2e-5 of the loop, 0.027 degrees and 4.7e-4 per mm of its neighbours
clear of the corners; set back 7.5 to 15, under its planes but by under 7.2e-4;
a hole in a cylinder filled with the cylinder's own second order; refusals.

An edge is left out of the shaded view only where its two faces meet
with one tangent plane (normals within 0.5 degrees) and one curvature
across the edge: at each station the faces' normal curvatures square to
the edge agree within 0.5 degrees' worth, |k1 - k2| <= 0.0087 x
max(|k|, 1/L), L the edge's length, so the continued faces turn apart
by no more than that over a radius of curvature or the edge's length.
Fillet boundaries (0 to 1/r), corner-patch joins and a plane tangent to
a cylinder are drawn again, straight ones included. A modelled thread's
flank pieces (one sweep) differ by at most 0.0046 and stay hidden.
Second derivatives of a spline surface now exist at a boundary point a
pcurve carries a rounding step past the knot range, as its point and
first derivatives already did.

Smoothness (normals within 0.5 degrees) and a crease are separate
verdicts. A crease is certified where the normals differ by more than
the evaluation can account for: each pcurve point's measured distance
off the edge's own curve times the faces' larger principal curvatures.
So a real crease too small to see is not drawn in the shading but stays
a pickable edge in the wireframe, overriding a coarse same-surface seam
fit, as before; exact tangent joins (fillets, seams, a thread's flank
pieces) are no crease.
The viewport's smooth-wall test expects the wireframe to draw
`edge_visible` edges: the offset ellipse's pieces meet at real creases
of 1e-4 rad that the old checker could not certify.

The M10 thread's 32 flank-piece joins meet with normals about 1.5e-6
degrees apart (measured independently with seam_diagnostics); each is

An edge is left out of the shaded view when its two faces' outward
normals, evaluated on their exact surfaces at each use's own pcurve,
agree within half a degree at eight stations along it (a seam one face
meets itself across is the same test with its two pcurves); it is a
protected crease when they differ by more. Replaces the special cases
for ruled clamped Bezier patches, planes, cylinders and cones. Fillet
tangent joins and corner-patch joins are hidden too; they stay
pickable and in the wireframe.

Seven labels of the thread dialog had no English catalog entry, so they stayed English in every
language (every_ui_label_literal_reaches_an_english_catalog_entry): Extent, Ends, Chamfer Angle,
Chamfer Depth, the two ISO 4753 hints and the designation hint. They are in
assets/locales/pending/thread-dialog-labels.json with Arabic, Hebrew, Japanese and Chinese, the
catalogs that must be complete. The ISO 4753 hints are looked up by id, and the designation hint
takes its example as {example}, so a right-to-left language places it where it reads.
pending_messages_are_in_the_catalogs compared a pending message with the catalog's text, which
for Arabic and Hebrew is in display order since #3768; it compares with that order now, as the
catalog stores it.

Each job fetched the prebuilt SMLib into target/ before Swatinem/rust-cache restored target/,
which replaced it, so every build that links SMLib stopped with "SMLib ... is not fetched"
(the Docker image of #7403). The fetch now follows the cache restore in every job.
develop (the SMLib kernel's trunk until it merges into main) gets main's push runs: CI runs on
pushes to it, a push compares against the last passing push to its own branch, and its runs save

v0.24.0 (format 39) saved a left-hand Thread or tapped Hole as `handedness: "left"`; this
branch replaced main's handedness (#4414) with the thread's `hand`, and features don't refuse
unknown fields, so such a design opened right-handed without a word. The pending format change
thread-hand.rs renames `handedness` to `hand` on Hole and Thread features (a `right` is
dropped, anything else refused).
Tapped holes take `hand` again, right or left (never both, and only with `thread`): the Hole
feature saves it, its thread is cut and annotated that way, solid.hole takes `hand?`, the hole
dialog's tapped rows have the thread dialog's Hand choice (without Both), editing a hole keeps
it, and hole presets save it under v0.24.0's `thread_options.handedness` key, so presets saved
by v0.24.0 recall it.
Test: a format-39 design with a left-hand thread and tapped hole opens left-handed; a hole's
`hand` refuses both and needs a thread.

tangency-labs/smlib's prebuilt workflow builds the C API once per commit for every Rust target
SolidCraft builds (Linux x86_64 and aarch64, macOS arm64 and x86_64, Windows x64, x86 and ARM64,
wasm32 with wasi-sdk's C++ runtime) and releases it as prebuilt-<commit>. SMLIB_PREBUILT pins each
archive's SHA-256. scripts/fetch-smlib.sh now downloads the host's archive (or the named
targets'), checks its hash and the commit it was built from, and falls back to the sources for a
target with no archive; --source fetches the sources, --pin writes SMLIB_PREBUILT from the
release. build.rs links a fetched archive whose hash matches the pin, else compiles as before,
now with -ffp-contract=off like the archives: every platform does the same arithmetic. No
network access in build.rs.
SMLIB_REV moves to 8b57e7e: the workflow, and fixes for MSVC (no directive inside a macro
argument, SM_PI for M_PI), the no-fused-multiply-add build and a test that needed a POSIX shell.

Main's reader (#1609, #3845, #3928) and the branch's met in the rebase, and the
tree kept main's gap closing: it moved a trim piece's end vertex onto the mean
of the gap's ends without changing its curve, and widened the STEP file's
stated accuracy to cover the move. SMLib checks each edge against its vertex at
the body's tolerance and refused the box (SmTrimmingTools Edge/Edge Gap 0.005 >
0.00425, rig 3845); the first piece of a trim curve with no start point was
also turned against the second (rig 3913, "edge loop is not connected").
The reader keeps main's structure (groups and subfigure instances as products,
names, placements, separate lumps as separate solids, the originating system)
and sews each group's surfaces the branch's way: each meeting point of two
pieces is one vertex, where most piece ends there agree, and a line or clamped
B-spline that misses it is rebuilt to end there exactly. Main's limits on which
gaps are one corner written loosely (0.1 mm, 5% of the shorter piece) decide
which meeting points are joined; the stated accuracy stays the file's. A trim
curve's first piece starts at its end away from the second when no start point
is given.

The IGES reader (#1609) writes each group and subfigure instance's placement as a
CARTESIAN_TRANSFORMATION_OPERATOR_3D_NON_UNIFORM. The branch's STEP reader took
only the uniform operator, and only its origin: every IGES assembly placement
was refused ("placement location: expected a reference") and put at the origin.
An operator, uniform or not, is now read as main reads it: its axes (the global
ones where omitted), its scales (1, and the first for the second and third) and
its origin, refused when singular. A placement may then scale, so the inverse
that maps one placement onto another inverts the linear part by its adjugate
instead of transposing it.

The corner pick (#5173) counts the edges meeting at a picked point; seams already
did not count, and now a tangent join between two spans of one smooth curve does
not either (4332: a chamfer on a spline rim was refused as two edges).
3383: the first occurrence is grounded by default on main, so the recipe
ungrounds it before moving it. 5024: a hole's position must lie on a face, so the
centre is on the box's top edge; the volume is half of the drilled cut, exact.

The branch's placement change (placing the model returns its error) made
world_state, home_camera, bounds, open_sketch_plane, the scene builders,
to_local and auto_operation return a Result. Main added callers of them
since the branch left it; they now take the error as the branch's own
callers do:
- engine: commands pass it on (`?`); helpers answering yes/no or "found"
(snap points, a face's normal, the DXF export check) answer no for a
model that cannot be placed. Frames keep the session for main's lazy body
frames (#6356) beside the placed model the picks are on; a library apply
maps its targets on that placed model. Before an extract or a link is
replaced, the placed model is taken or the command fails.
- ui: panels, picks, dialogs and previews read the placed model through
open_meshing::session_world (none when it cannot be placed: the viewport
says why); Home and Fit frame nothing then.
- cli: the usage table is main's, with kernel-cases in it (a resolution of
the rig's commit had kept the branch's whole file).
- tests read the Results with unwrap, and main's tests of Body::tessellate
mesh through Body::mesh. Main's test of saved boolean retries goes (the
branch saves none), as does the thread half of its dialog rendering test
(the branch's thread dialog has its own); the tapped hole half stays.
- What no caller uses after the merge goes: a mesh body's span, the metric
thread refusal text, and the revolve's targets-as-shown model (main used
it for the coplanar run-on the branch removed). Main's SolidWorks Y-up
test reads the exporting system's name (the branch's STEP header has no
preprocessor or description fields).

Main gave the Thread feature two things the branch's thread rework (forms,
hands, starts, extents, runouts, tips on ThreadAsk) was written without:
- Tapped holes take catalogue sizes (ISO metric and the catalogued UNC/UNF,
G and Rp sizes): `ThreadAsk::tapped` reads the designation from the tapped
catalogue, names the thread as the catalogue does, and fits a size that is
not metric to the hole drilled for it (its tap drill). The hole feature
asks for its thread this way.
- A modelled external thread on a shaft thicker than it turns the shaft down
to its major diameter first (#4256): main's `thread_turn` makes the ring,
the shaft is cut by it, and the grooves and a chamfered tip are cut at the
turned radius. Such a shaft fits the thread.
ThreadInfo keeps the radius of the face it is on, which main's cosmetic
thread display draws at (0 in a state saved without it).

The branch rebased onto main keeps each of its commits; where both sides
changed the same code, these are the pieces neither side's commit had.
- Cargo: one [features] table in the CLI's manifest (two met in the merge).
- geom: a NURBS surface's `closed` set once in a placed copy (both sides
added it).
- kernel: the whole-face extrude tools (#2040) work around truck's boolean
on truck types, which left the workspace with the SMLib kernel; the
module, its tests and the doc crate's tool and tests go. The display
planner's flat fill (tess/fallback.rs) has no caller with the schema 4
mesher, and the tessellator's seam and uv modules are the branch's. A
body's boundary tolerance from a STEP file belongs to the truck body the
schema 4 record replaced: `with_boundary_tol` goes. `unmeshed_faces`
counts the coarse mesh as the branch does. A loft's section re-split
passes the lead's perimeter shares to main's `resample` (a circle breaks
there when the matched corners do not go round in order). Main's tests of
the mesh-based measure (the SMLib kernel measures exactly) and of the
IGES preprocessor name (no such field on the branch's import record) go.
- doc: a feature result carries no boolean diagnostics on the branch, so
the model cache neither writes nor reads them, and a pattern copy's miss
test runs the intersect as it is. A placed body's worker result is a
Result: a body taken from the previous placement is Ok. A thread's
clipboard remap takes main's arguments, the tapped catalogue names a
metric size by ThreadForm::Metric, and main's tests unwrap the placing
calls that return their error.

The r7 on the vertical edge runs on (tangent chain) up the side's arc on the
r5 round, a circle of radius 5: its contact line on that face would be the arc
offset 7 towards its centre, so no such round exists and the right answer is
a clean refusal. 018 picks a radius that fits (r2: 11 faces, inside the box).

mitres, shelled open below) and 014 (drafted box with tilted rounds:
every level section loses the same elliptic corner) now check closed-form
volumes, exact counts and bbox (014 also its centre of mass). 011, the
running part shelled 1.5, checks the part less its cavity built feature
by feature, the offset faces meeting sharp at concave edges as in the
rest of the tier (a distance-based offset would differ by 0.3%). All hold
on SMLib (worst 1e-6 relative).

It passed on one valid body alone. It now checks the chamfer's prism, the

010, 011 and 012 passed on one valid body alone. 010 (r7 then an r3 chain
round its arc) and 011 (two r5 rounds in a mitre) now check closed-form
volumes, counts and bbox; 012's variable round takes only its edge and
runs on into the vertical round's column, so its volume is graded as the
interval between that end carried on as a constant r5 tube and as its
growing radius. All hold on SMLib (worst 4e-8 relative; 012 at the
growing-radius end).

07, 08, 09, 11 and 12 passed on one valid body alone. Each now checks
its volume, bbox and (where derived) counts, area and centre of mass:
the three-section loft is the degree-2 interpolant r = 10 + (z-20)^2/40;
the square-to-circle loft a ruled prismatoid, its mixed area from the
sides ruled to rational quarter arcs; the periodic fit spline the cyclic

their crossing integrated exactly per wedge; the cap's union integrated
as y-intervals over x and z. All hold on SMLib (worst 9e-8 relative).

The generator had fallen behind the tree: it no longer wrote 02/021-025,
03/010, 04/011-012 and 09/012-015, and its 07/016 lacked the second round's
tangent_chain. Each is now built in cases.py; the two reporters' scripts
(04/011, 04/012) are kept verbatim in reported.py. Regenerating reproduces
the tree exactly; the only file changes are the generator's own format
(volumes to 9 decimals, one-space indent, a final newline), all under 1e-8

Three r5 rounds at (60,40,20) set back 8: the volume between the convex
hull of the body on the corner cube's faces and the rounds' prisms (both
bounds closed form or a sampled hull below the true one), the box's bbox,
and SMLib's setback-patch topology (15 faces, 36 edges, 23 vertices).

FeatureKind::Fillet gains setbacks (serde default: none, omitted when empty),
each a corner vertex and a length expression; a fillet with setbacks is
evaluated by kernel::fillet_setback. Constant-radius exact fillets with
rolling corners only (refused otherwise, in the command and in evaluation).
One distance per corner: SMLib keeps one setback per corner, not per edge.

Each (point, distance) sets back the corner at the body's nearest vertex: its

rounds' prisms bounds, 15/36/23 topology, the box's bbox) and on refusals.

At a pole or apex `EvalSurface::eval` takes the normal from a step beside the
point, trying (+h, +h) first. At the far end of an interval (a sphere's north
pole at u = 1) that step lands past the end, where the extrapolated surface
folds back over the pole, and the normal came out turned over: the pole vertex
shaded dark with a light ring around it (ladder 01/005, every sphere and dome).
Steps now stay inside the active interval of a spline or a revolution's
profile. The pole test checked only that the normal was radial, either way;
it now checks the side too.

Sizes, designations and the face's size come from ThreadForm (sizes, parse,
format) and suggested_thread_in, per form; the dialog's own trapezoidal and
buttress lists are gone. Acme sizes are listed by designation. The square
thread, which the command refuses (no standard defines it), is not offered.
Editing a thread reopens its form, hand, starts, extent (length or up to, with
its pick), start end, runouts, tip and steep flank, and OK gives them back.

Ladder 06/009 had no way to ask for one: "solid.thread has no runout (vanishing thread)
length". With SMLib's smlib_screw_sweep_radial (replay e7acea1):
- smlib: the FFI binding and Brep::screw_sweep_radial, the profile moved off the axis by a
piecewise linear law of the turn; crate test: a tooth moved out 1 mm over three turns has
A 2π (c turns + ∫ offset dt).
- kernel: sweep_helix_radial, sharing sweep_helix's checks (helix_profile).
- doc: `ease_in`, `ease_out` (a length, or ISO 3508's standard 2.5 P or short 1.25 P) fade the
groove over that length, its section moving out of the material as it turns (outward for a
shaft, inward for a nut). ease_in is at the end the thread starts from. The runout lies past
the full-form length: beyond a square stop, before a shoulder up to its clearance; at a free
end inside the face. Runouts longer than the thread are refused. No end gets one by default,
so saved threads keep their geometry.
The cut is the integral over the turn of the clipped section's 2π∫ r dA: engine test (2.5 P
and 1.25 P between two collars) within the sweep's wall tolerance times the runouts' wall area
(0.029 against a 0.036 mm³ bound), ladder 06/009 (004's shaft, a 2 P runout before the
shoulder) graded in closed form (measured 1.7e-6 off).

`tip: chamfer` cuts ISO 4753's chamfered end at each free end a modelled external thread
reaches, after the groove, so the last teeth taper into the cone instead of ending in a
ragged first turn: the material outside a cone `chamfer_angle` to the axis (default 45°)
reaching d_f = d - 2 `chamfer_depth` at the face's end (default the external minor diameter,
the largest the standard allows), a revolved ring cut by one boolean per end. Past the end the
ring keeps to the radii the groove's overrun already cuts. An internal thread is refused (its
entry takes the hole's countersink), as is a tip with no free end or on a cosmetic thread.
The cone is axisymmetric and cut after the screw-symmetric groove, so the volume is the stock's
chamfered section with the thread's material fraction: engine test (both ends 45°, and 30°
x 0.5 mm at a shaft's one free end above a collar) within 1e-4, ladder 06/017 (measured

Ladder 06/008 had no way to ask for one: "solid.thread has no start count". `starts: n` (1 to
8) cuts n grooves of lead n x P, the j-th a j/n turn round from the first (the same helix j
pitches along), in one boolean with their union. A designation that gives the lead
(M16xPh3P1.5, Tr40x14(P7)) gives the starts, and a `starts` that disagrees is refused. The
helix's self-clearance check and the turn limit use the lead.
Over the same length n grooves of lead nP take the volume of one start of pitch P: engine test
(2 and 3 starts, M10xPh3P1.5) within 1e-4 of the closed form, ladder 06/008 graded as 001

Only the ISO metric 60° thread existed. Forms now (crates/doc/src/thread_forms.rs, values and
sources in docs/threads.md): ISO metric (ISO 68-1), trapezoidal (ISO 2904 design profile, ISO
2902 sizes), general purpose Acme (ASME B1.5), metric buttress 3°/30° (DIN 513), buttress inch
7°/45° (ASME B1.9 basic profile). Each has its groove as a straight-flanked polygon, its standard
sizes (none for ASME buttress), its designations (M10, M16xPh3P1.5, Tr40x14(P7), S20x4,
1/2-10 ACME, 2.5-8 BUTT) and the size that fits a face. The square thread is refused: no current
standard defines it.
`hand: right | left | both`: a left-handed groove is the screw motion about the reversed axis
rising along it; both cuts the two grooves, crossing, in one boolean. `steep_flank` turns a
buttress. The design diameters are checked against the published tables (ISO 2904/DIN 103,
DIN 513 via IS 4696-3); every form's cut against 2π∫ r w(r) dr per turn to 1e-4 in engine tests
and to 1e-4 in ladder 06/011 to 016 (they measure within 5e-7).
FeatureKind::Thread holds every option the command has (form, hand, starts, ease_in, ease_out,
tip, chamfer_angle, chamfer_depth, steep_flank, all defaulted so saved threads load unchanged);
starts, runouts and the chamfered tip are refused as not built yet. suggested_thread_in takes the

A thread of some length ran from "the end of the face nearest the pick", a coin toss for a
pick in the middle (rig 602's 4 mm thread meant for the free bottom end ran at the head end,
cutting 1.17 mm into the hex), and every thread end at a face end got a one-pitch overrun,
which at a shoulder gouged the material past it (ladder 06/004 cut 0.9% of its volume out of
the collar).
- kernel: material_in_ring, the exact intersection of a body with a ring about a cylinder
face's axis, by an SMLib boolean.
- doc: a face end is free when no material lies past it, over the span the groove's one-pitch
overrun reaches beyond its first pitch, within the radii the groove cuts (a cap, a chamfer
the groove runs out through, a counterbore). At a free end the groove runs out as before; at
a closed one (a shoulder, a head, a blind hole's bottom) it stops with its widest part clear
of it; inside the face it stops square.
- doc: a thread of some length starts at the end nearest `from`, else at the face's only free
end, else at the end the pick lies within a third of the face of; a pick in the middle of a
face whose ends are alike is refused, naming `from`. A length as long as the face runs the
whole face. `up_to` a plane or a point's place along the axis. New fields `from`, `up_to`
default to none, so saved threads keep their meaning where it was not a coin toss.
- engine: solid.thread takes extent (full|length|up_to), from and up_to.
- ladder 06/003 (now with `from`), 004 and 007 are graded by volume and centre of mass in
closed form (a square stop inside material removes exactly length/P turns, the section being
symmetric); rig 602's method says why the thread is at the bottom, tolerance 0.02%.

Form (ISO metric, trapezoidal, Acme, ISO and ASME buttress, square), size and

A face's boundary nodes are its edges', shared with the neighbouring face.
On a nearly straight stretch (the base of a thread flank's corner, clipped by
a hex head's flats, on an iso-line of the helix) refinement met slivers
between consecutive boundary nodes: their centroid, or the middle of their
inner edge, lies on the boundary chord to rounding. Inserting it split the
boundary constraint, and the face was refused ("boundary crosses itself";
rig threads/602, refused while the body was meshed to pick the fillet's
edges). A sliver whose centroid lies on the boundary is now split at its
inner edges' middles, and a refinement point that lands on the boundary is
not inserted.
The 602 engine test assumed the old kernel's faceted thread (over 1000
faces); with SMLib the thread is exact, and the test now checks that the
fillet finishes and removes a little material.

A notch cut into a sheet's base is a cut-out, so the base outline that
edge_at and the edge names read has no edge along it: a flange picked on
the notch's bottom edge took the name of the nearest outline edge (the
plate's far edge) and was built on the stretch of it the notch left. A
pick nearer a notch's edge than any outline edge now names no edge, and
the flange runs the base's outline round that notch first, keeping as a
cut-out only what it takes of the flanges, then trims and bends as on any
edge of the outline. The edge of a hole inside the base is refused.

Convert to Sheet Metal keeps a shell's (and a plate's) own thickness, but
the rule's values were evaluated with `Thickness` the rule's: under the
default rule (2.5 mm, bend radius `Thickness`) an L 2 mm thick with its
bend modelled R 2 was rebuilt bent R 2.5, losing 8.58 mm3 (2659.911
against 2668.496), and its gap and reliefs followed 2.5 mm too. The rule
is now evaluated for the sheet's thickness (Document::rule_values_at):
in the conversion once the shell's thickness is known, for a converted
plate, and for the flanges, hems and folds added to an existing sheet.

solid.mirror and solid.pattern of bodies pushed each copy as a plain body:
no sheet model went with it, so its flat pattern, DXF and bend table were
refused ("`Body1 (2)` is not a sheet metal body"). Each copy now gets its
source's sheet model moved with it (SheetBody::moved). A reflection turns
the frame's handedness over, so a mirrored copy's frame sits on the moved
top face, thickness growing back toward the moved bottom: the same blank,
each bend turning the other way, machining depths taken from the other
face. A sheet feature on the copy rebuilds it in place.

The countersink's cone started 1% of the drilled body's size above the
entry face, widening on to rc + top tan(half) there, so above the face
it cut beyond the countersink's rim: a wall 0.15 mm from the rim was
notched (#5041, 12 faces instead of 10). The tool is now one revolved
profile: the cone from its rim on the face to just inside the bore, and
above the face the rim's own cylinder, as the bore's cylinder runs on
above it. The cone stays the profile's first segment (csink:side:0).

A Combine took its tools in their own component's coordinates and joined
them to a target kept in another component's: a root body joined into a
body of a component turned a quarter turn landed where the turn carries
its root coordinates (#3383, 2 shells and 17000 mm3 instead of one solid
of 16750). Each tool is now moved through its own placement and the
inverse of the target's (component placement, then body offset), as
state_in_frame places bodies, and a combine's cache key follows the
placements so moving a component recomputes it.

The case's base is a stadium ring (r 3..5 arcs, centres 20 apart, z 0..2),
as its description and expected volume (2 (80 + 16 pi) for the base) say,
but its extrude picked no profile, and "all profiles" is every drawn region:
the ring and the stadium island inside it. The base came out filled and the

The record's torus label is a ring torus (major > minor; the validator
refuses any other). SMLib keeps horn and spindle tori: a half disc revolved
about a line through its rim's end is a horn torus, its major radius a
rounding below its minor, and the export wrote it as a torus label the
record then refused (rig sweeps/4007, "ring torus radii"). Such a face is
now its NURBS form, unlabelled, which is its geometry in any case.

solid.shell refused an empty face list ("select 1…1000 faces"), and the
shell feature found its body from the first face picked. SMLib shells with no
face opened (the void sealed inside, its own shell): the command now takes
`faces: []`, the feature shells the one body there is or the one named
(`body`), and an outside or both-ways shell pushes no open face out of the
cavity. Rig shell/4009 declares the void's shell (`shells: 2`), as its method
says.

Where a face's loops pass a vertex more than once (two holes touching at a
point, a loop through another hole's corner), each pass took its parameters
from the pcurve of the edge leaving it, and the two pcurves round them 1e-14
apart. The triangulation got two nodes 1e-14 apart with constraints crossing
between them and refused the face ("boundary crosses itself"): rig 307, 3092
and 3887. A pass whose parameters agree with the vertex's first pass to that
rounding (1e-9 relative) now takes the first's; farther apart they are two
places of the surface (a seam's two sides, a closed spline's ends).
Rig 494 now fails: its revolved face has a dead-end edge walked down and back
up in one loop, which met the triangulation as a needle 1e-14 wide and now as
the slit it is.

fillet_max bisected the radius down on any error of a candidate fillet,
not only KernelError::TooLarge, and fillet_max_each fell back to one
radius for all on any error of a group or of the combined fillet. A
kernel failure at the radius asked for (or at any candidate) came back
as a smaller radius reported as "the largest that fits".
fillet_max and fillet_max_each now return Result<Option<..>>: only
TooLarge narrows the search or falls back to one radius, and any other
error is passed on. Ok(None) is still "no radius fits". The doc's
FilletFit::Reduce passes the error on. The test of a point with no edge

over that box, so where the boundary peaks between two samples the form
stopped short of its edge: the re-imported rod's bore ended at v = 9.99977
while its intersection with the rod reaches 10, and SMLib found the edge

form::extent unwrapped each loop of a face from its own first point, so a
hole beside the seam (a cross bore through a rod at the rod's seam angle)
came out a period away from the outer loop. The box over both was more than a
turn, cut to one turn from the hole: the face's NURBS form ran over quarters
3..7 while its seam uses lay at 4 and 8, and SMLib found the re-imported
rod's edge ends outside its face domain (SmBrep #70-#72). Each loop after the

tangent_chain followed tangent edges without looking at their convexity: a boss's concave base
arc that runs on tangentially as the convex rim of the overhang above it (rig fillets/4174,
4369) and a convex outline running into the concave edges under an overhang (4365) were sent to
SMLib as one chain. No round can pass from one side of the faces to the other, the cases'
answers stop at that vertex, and SMLib rightly refused the request (1001 in its Nx2 corner).
A chain no longer runs on into an edge of the other convexity: convex(e, v) tells, from the
second face's natural normal, the loop's direction and the first face's normal, whether the
faces meet at less than 180 degrees inside the body. With SMLib's corner and end fixes this
makes rig 4174, 4365 and 4369 pass with their analytic answers; nothing else changes.

Rig case shell/4711 (a 60 x 40 x 10 block, an r3 through hole at (22.5, 7), a 10 x 10 notch on
the front edge, shelled 2 open at the bottom) failed with "SMLib shell: operation: SMLib failed
(status 1027)". The hole is 4 = 2 x 2 from the front face: the hole wall's offset (r5) is tangent
to the front's at (22.5, 2), the walls meet along a line and the cavity would pinch to zero
thickness there, which is no solid. Refusing it is right; the refusal did not say why.
SMLib now refuses an offset whose walls would meet with its own status, SMLIB_ERR_WALLS_TOUCH
(-1110). The smlib crate reads it as Error::WallsTouch; the kernel's offset backend turns it into
a sentence with the wall, as blends turn NoRoom into one: "shell: the 2 mm walls would meet along
a line (between a hole and the side, for example), which leaves no solid there; use a thinner or
thicker wall, or move the feature". Thicker builds too (SMLib shells 4711 at 2.5, the walls
crossing and merging between the hole and the front), so the sentence offers both.
4711 expects that refusal and its message ("outcome": "refused", "refusal"), its "what" and
"method" saying why: the wall is 4 = 2 x 2, the walls meet along a line. Tests: the smlib crate
shells 4711 built from primitives (2 refused as WallsTouch, 1.5 and 2.5 valid), the kernel a
plate whose hole is 3 from its side at 1.5 (refused, with "the 1.5 mm walls would meet along a
line").
Results (run-sc.sh against SMLib a759622's code, which differs from the tree run only in

SMLib now builds a round or chamfer whose rail runs off its face across a cliff (an opening's
rim, the body's outline): the blend is made as if its faces continued and what it removes is
subtracted, so it never bridges an opening (owner decision for rig 5158/5181; fork commit
"SMLib, capi: a convex blend overflowing a cliff is subtracted from the body"). The tests that
expected a refusal for such blends now expect the body, each answer from the geometry:
- variable_radius_on_a_box_edge: 2 -> 50 on the 10x20x30 box's top edge builds at
3546.18767939 (circular sections in y = const, the r x r square less the quarter disc,
clipped to the box; rel 1e-4).
- variable_radius_from_a_spline: the "big" law builds at 6000 - 726.5334566720 (de Boor law,
split at the knot and where r crosses 10).
- a_chamfer_meets_sloped_end_planes: chamfer 25 removes 11500 - 4625 * slope
(integral of 40 - 2 * slope * y over z >= y - 5).
- g2_fillet_refuses_invalid_geometry: G2 at 25 builds at 6138.1606889 (the quintic section
with control points at thirds, clipped to 20x20, along 20).
- fillet_max_each_reduces_only_where_the_radius_does_not_fit: both edges take 4, 24438.7317761.
- hostile_inputs_are_errors: chamfer 30 on the cube builds at 1000 (y + z <= 10 along 20);
R50 still fails.
- kernel-cases fillets/1080: the 9 mm chamfer into the openings builds at 3350
(method in expected.json).

Where a cut-out's corner touches the outline (a triangle on the sheet's edge in a bend), four
walls meet along the corner's line. The touching sew paired them round the empty wedges and
gave each fan at the corner its own vertex, so a cap kept its outline and the cut-out as two
loops with a vertex each at one point: SMLib refuses that face (coincident vertices, loops
touching: its face tests 32, 38 and 39), and the bend face's two corners, a hair apart in
(u, v), left a boundary no triangulation follows.
The walls are paired round the wedges of material, as SMLib keeps a solid touching itself along
a line: an edge per wedge, the two sharing their end vertices. A face's loops that meet at a
vertex are joined there into one loop through it twice, SMLib's form of such a face.
With SMLib's face builder taking the same profile (an extrusion of the plate and its
cut-out), fixes rig sheet-metal/1095.

A loft cut from a block's whole outline (flush with its sides) down to a pad cuts the slab
above it loose: the slab and the rest touch along the outline's four edges, round the pocket
the loft leaves. SMLib keeps the pocket as a void region of its own (its check finds the body
valid): its one runtime shell is the slab's underside and the loft's faces, so the slab's
material shell faces two empty runtime shells, the infinite region's and the pocket's, and so
does the rest's. The export made one record shell per pair of empty and material runtime
shells, so each solid's closed boundary came out as two open shells ("an open, wire or vertex
shell lies in one region").
A record shell is now one material runtime shell, whatever empty shells its faces face. Empty
regions one solid's boundary faces together are one record region: the infinite region where
it is among them, else the void whose outer shell bounds it alone. The pocket, which no record
shell bounds once the solids' shared edges are split, is part of the empty space round them.

With touching: separate (the default) a join groups the joined body's
pieces by face contact. The groups that hold the material of the body
before the feature stay in it (each unless it touches one already kept;
the first group where the lineage doesn't say), and so do the groups that
touch nothing: a virtual grouping later operations take as one body. Every
other group that touches another along an edge or at a point becomes a
body of its own, and the feature's notice says so. The joined body keeps
its name and never holds an edge or point contact. A join that only
grouped pieces apart gives no notice, so KeptSeparate::Apart is gone.
one_body still keeps every piece in one body.
SMLib's export copies an edge or vertex that touching solids share once
per solid, so the record never listed those contacts:
Brep::region_contacts now takes such copies (the same curve and interval
between vertices at the same points, a vertex at the same point) as the
edge or vertex they share. A contact SMLib leaves out of the topology (the
3612 spoke tangent to its hub) is found on the exact geometry, the least
distance within the record tolerance, and reported as KeptSeparate::
Touching ("along a line or at a point").
The pending format change join-touching-bodies stays: older designs kept
pieces touching along an edge or at a point in one body too. Its notes say
so, and the reopened legacy emboss still expects touching: one_body.

buried tab and a_join_adds_only_its_sketch's 0.1 mm gap.
join_meeting_nothing_keeps_the_first_body expects one body and no notice.
The #3378 spoke stays 1 mm inside the hub.
New tests: blocks touching along an edge are split with the along-an-edge
notice; blocks apart stay one body without one; a ring with an arm on its
corner edge and a hub apart gives ring and hub in one body and the arm on
its own (doc); the engine's notice for an edge contact; the record's
contacts of cubes sharing an edge or a vertex (kernel).

Each edge is sampled to the chord tolerance on its own, so where two curves of one face run
closer together than their chords sag (the two arcs of a thin lune, the sliver caps of a
joined ring of cylinder segments) the chords crossed although the curves do not, and no
triangulation follows such a boundary ("boundary crosses itself").
After the edges are sampled, every face's boundary is checked for chords that cross another
of the face, in its loop or another, and on a closed surface across whole periods (chords
ending on a pole are left out). The edge segments that cross are halved at their curve
parameter's middle, on the edge, so every face of the edge gets the same new nodes, and the
faces of the edges split are checked again until no chords cross. A boundary still crossing
after 16 rounds, or an edge past its node cap, is an error naming the face and the edges.

Every edge segment now spans at most a quarter turn of its curve, whatever the chord
tolerance: a hole far below the tolerance (a 1 mm hole through a 990 mm plate at a 2 mm
chord) stays a polygon with area, where each half arc had been one chord and the two
chords lay on one line, a hole of no area.
The boundary check takes boundary nodes at the very same (u, v) as one vertex, as the
triangulation does: two loops touching at a vertex they share (a ring standing on a
perforated plate, tangent to the holes beside it) bound a face the triangles follow. A
seam's two uses, one point in space a period apart in (u, v), stay two.

seam_flags matched only an edge between two faces on one curved surface.
A whole turn of a cylinder is one face whose seam it uses twice, and
history::edge_faces lists that face once, so the seam came out as [x]
and was never flagged: it was drawn and picked, and a blend pick at the
vertex where it meets a rim (ladder 07-fillets/017's (23, 15, 20) on a
boss's base circle) resolved to the seam, which SMLib then rejected. An
edge both of whose uses lie on one curved face is now a seam too, for
every consumer of the flag (display, picking, blend resolve, projection).
The blend's own edge selection took the plain nearest edge: the tangent
chain seeded from it and grew into seams (a pick at the top of a boss's
seam ran down it into the base round's seam, ladder 08-chamfers/008), and
the variable fillet's edge and the fillet's grouping of picks could
differ from the edge the blend resolved. They now take the edges the
blend's resolve picks, and a chain never grows into a seam or a smooth
join.

Every feature command reads touching (separate | one_body) as it reads
participants; the box and extrude contracts declare it. A feature result
carries notice {message, contact, action} when its join kept solids
apart ("These bodies only touch along an edge, so they were kept as
separate bodies."), the action a timeline.edit that sets touching to
one_body; programmatic calls open nothing.
Tests adjusted: join_meeting_nothing_keeps_the_first_body now expects the
separate body and its notice by default and the old single body of two
lumps with touching one_body; the schema key lists and the
FeatureResult literal gain the new fields.
Engine tests whose subject is a body joined from pieces that share no
volume make it with touching: one_body (posts joined while apart, a
cube joined clear of another, a cylinder joined clear of a ring, a tab
joined in a component); a legacy design reopens with touching: one_body
on its emboss; the 0.1 mm gap of a_join_adds_only_its_sketch leaves the
block a body of its own; and the #3378 spoke starts 1 mm inside the hub,
so the join merges its targets instead of touching the hub along a line.

body's pieces that share no face into bodies of their own, named, with

several pieces. The state records how the kept-apart pieces met
(KeptSeparate: along an edge, at a point, apart) for the feature's

Older builds kept every join's pieces in one body: the pending format

The display's smooth joins were certified only between ruled B-spline patches
along a Line record. SMLib gives an extruded profile's rulings as degree-1
B-splines of two control points, and sweeps a profile curve within tolerance of
an arc as a cylinder (a ring of 256 cubics is 512 cylinder faces), so no join
was certified. A straight edge is a line or such a B-spline; a plane, cylinder or
cone gives its outward normal along the edge in closed form at both ends (their
difference is the uncertainty, so an edge that is no ruling certifies nothing).
The closed-edge fixture cuts its hole with one circle: SMLib trims a loop of
eight cubics as eight edges.

The kernel blends exactly the edges given; the Fillet and Chamfer features
expand each pick to its tangent chain (kernel::tangent_chain) before the call
(4593fd07). Six tests written before that passed one pick and expected the
chain: they now ask for it as the features do, with their analytic expectations
unchanged (10 faces along the rounded corner, the sphere corners of #1557, the
boss's half circle, the rounded rectangle's tiny end, the rounded box's loops).
blend_smlib's notes no longer say SMLib follows the chains.
fillet_tabbed_plate_outer_loop_and_partial_selection_after_hole is left as it

A degree-1 patch of four control points on a parallelogram (a plane as an IGES

take the plane's closed forms instead of going to SMLib (which drew the rim
circle of 3806's base as a 385-point spline).
SMLib may run a one-face sheet's loop against ours. A use's pcurve is the same
either way, so the loop's way round is read from an edge the face uses once and
every use is matched with it (3806 failed with 'a use SMLib did not keep').

SMLib alone, an open sheet with the trims it has and without the others, and
SMLib makes those as it makes every trim it needs (GetOrCreateUVTrimCurve on

its exact pcurve on the label: u fixed at the arc's azimuth, v its angle from the outward

- A placed revolution has a NURBS form: its profile's control points turned about the axis on
the quarter grid from angle zero, weights multiplied, then its matrix; the record takes forms on
revolutions.
- `form::extent`: a face's parameter box from its boundary projected on its label (the collapsed

`form::edge` is the one rule sew and the STEP reader share: a circle about a revolved face's
axis is labelled on that face's frame, and a circle or ellipse edge gets its form. The STEP
reader now gives every imported edge its label and form before any pcurve, and every
cylinder, cone, sphere and torus face its form over the extent its label's pcurves give; the
pcurves, the outer-loop choice and the turn-over test then run on the forms, and the record
carries them.
With the pcurve fit turned off, the STEP and IGES circle cases pass (8 of the 9 import cases

A flat-pattern edge folded across a bend is a helix, which no NURBS is: sheet metal already

the point and first three derivatives of its angle about the axis (through the form's quarter
parameter, by the chain rule) and of its height along it, broken where the angle crosses a
quarter (the form's parameter is only once differentiable there), halved until they lift onto

The bend's rim arcs carried frames of their own (x toward the arc's start), a fraction of a
quarter from the bend cylinder's, so their forms were off the cylinder's quarter grid and no
straight pcurve lay along them. `form::on_frame` relabels such a circle on the face's frame (the
same circle, its interval shifted); its form is then on the face's grid, its pcurve u = ±s + c.
`along` takes u or v as the edge's parameter either way along, offset. The volume test steps to
a pcurve's ends exactly (t0(1-f) + t1 f), as an interval's end may now carry rounding.
With the fit off, 38 of the 44 sew cases pass (from 29). With it on, the rig is unchanged
(333/372, ladder 101/116, no case changed).

Every circle and ellipse edge sew builds now carries its NURBS form, its interval in the form's
parameter; every cylinder, cone, sphere and torus face its form over the extent its label's
pcurves give; and every pcurve is computed on the forms, so a bend's rim circle is a straight
line on the bend and an affine image on the flange, exactly. The volume test evaluates the faces
on their forms. A form interval's end within rounding past its last quarter stays on it.
With the pcurve fit turned off, 29 of the 44 sew cases that needed it pass (from none); with it
on, all 44 pass as before.

On a plane, a B-spline or NURBS edge's control points go through the plane's affine parameters
and the result is cut exactly (bspline::segment) to the edge's interval, so a circle's form gives
its exact pcurve on any plane. On a spline face (a NURBS form), an edge that runs along the face's
parameters at its own pace gets the straight (u, v) line it is: between its ends' parameters, or
with u or v its own parameter (a rim on the same quarter grid). Each is taken only where it lifts
onto the edge to within 1e-9 of the geometry's size; nothing is fitted.

A form's parameter is now the angle's quarter on its frame plus the arc's parameter in it, and a
form spans the quarters its interval needs (up to five for a turn). Every form on one frame has
the same parameter at the same angle, so a circle edge and the cylinder it bounds agree along it,
and an arc across the frame's x axis, or starting anywhere, has a form. Traces its label to 1e-14
on such arcs, negative angles and a turn from 30 degrees.

`brep::form` builds each analytic kind's exact B-spline the way SMLib holds its own: a circle
or ellipse as four rational quadratic quarter arcs from its frame's x axis on [0, 4] (angle and
parameter related in closed form), a cylinder or cone as that circle times a line along the axis,
a sphere as the circle times a half circle of latitude, a torus as the circle times its tube's
circle, a line as the degree-1 B-spline on its own parameter. A circle and every face it bounds
then share one parameterisation. Each traces its label to 1e-14.

The assembly kept a face's domain and pcurves, which are in its NURBS form's parameters, but
dropped the form and computed new pcurves and the domain on the analytic surface. The form now
travels with the face, and its pcurves and domain are computed on it.

A shell's `forward` is about the surface the face's (u, v) are on, its NURBS form when it has
one, which may run against its cylinder, cone, sphere or torus. The kernel read it against the
analytic surface, so a fillet's bore whose form runs the other way was a shaft and an M10 thread
was refused in its 8.5 mm hole. `Face::form_turns` says when the form turns the normal.

No floor of ours on tolerances (1e-6 of the body's size, 30 times SMLib's 1e-5 default): the
record's tolerances go back into SMLib, which approximates to them, so the floor coarsened every
later operation. No recognition of NURBS edges as lines or circles: an edge is a circle where
SMLib holds an SmCircle (with its NURBS form), and a NURBS edge keeps SMLib's trims on its own
parameter. crashes/2992 and sweeps/1853 pass.

Edge::curve_interval (and brep::curve_interval for assemble's edges) gives the interval on the
edge's curve itself: a form circle's angles of its ends, its frame turned by the SMLib conversion
so the angle grows along the NURBS. lip and the ruled surfaces read arcs by it; the hull, the
blend tangents, the patch pcurves, point paths, IGES output and the prism runs evaluate on
Edge::parameters. assemble carries an edge's form through.

The SMLib conversion reads and writes EDGE_NURBS_FORM: a circle edge's record keeps the circle

The edge mirror of a face's NURBS form: Edge::nurbs keeps the NURBS SMLib holds a conic as, and

(valid_position, exploded view, fastener at a point, STEP insert matrix).
ui: panels, picks and hovers read the session's placed model through
open_meshing::session_world; a model that cannot be placed shows no placed bodies, and the

Every SMLib analytic surface is a B-spline surface, and its trims are in that NURBS's
parameters. Face::nurbs keeps that NURBS: the face's domain and pcurves are its (u, v), and
`surface` says what the face is. Face::parameters is the surface every (u, v) evaluation uses.
The SMLib conversion reads and writes it (fork FACE_NURBS_FORM, SMLIB_REV c4483f6); the STEP

Exporters write a plane as a CONICAL_SURFACE whose semi-angle falls a whisker
short of 90 degrees (#4006: pi/2 - 7e-12): its height over the face spans
4e-11, a parameterisation ill-conditioned for everything downstream. The
reader now measures the cone's deviation from its limit plane (the plane
through the placement across the axis) over the face's boundary points and,
should the face hold the axis, the apex; within the file's distance
uncertainty the face's surface is that plane, oriented as STEP's normal.
One criterion, the deviation over the extent against the tolerance; no

Loop2::circle and circle_from gave two half arcs, so everything built from a circle came out in
two: an extruded wall in two faces, a rim in two edges, and so every round, chamfer or sweep on
it in two B-spline halves that SMLib cannot join (two separately parameterised arcs meet at
different curve parameters, SmVertex::IsTopologicalVertex; different free-form surfaces are not
topological, SmEdge::IsTopological). A circle is now one arc of a whole turn from its start
angle: one closed edge, one wall with a seam, one round. Sketch circles, the cylinder builder
(circle_from at its seam angle) and every other builder take it through Loop2; SMLib's arc
curves take a whole turn (smlib_sweeps clamps to one) and ArcSweepCylinder makes the whole
cylinder.

Seven sheet-metal cases failed in smlib_planar_faces (status 1001/1006). Every refused
curve list, in the rig's dumps, has curves of which more than two meet at one end point:
flange regions of one flat pattern touching at their corners (405, 349 x2, 436, 1481, 725,
723) and an outline passing a point twice where a cut-out's corner lies on the sheet's edge
(1095). SmBrep::CreatePlanarFacesWith3DCurves, behind SmApiCreatePlanarFaces, documents
that it fails for such "spine points (where more than two curves share a common
end-point)" (SmBrep.cpp); the sheet handed it all of an operand's loops at once.
A sheet is now built one simple loop at a time: each loop (outer counter-clockwise, holes
clockwise) split where it passes a point twice, each simple loop its own planar face, the
counter-clockwise ones united and the clockwise ones taken away with SMLib's 2D boolean,
which takes faces touching at a point. extrude_planar_regions uses the same sheet.
The read-back keeps the contract the regions had: a face's loop that passes a point twice
(a cut-out touching the outline) comes back as simple loops, counter-clockwise pieces
material and clockwise ones holes of the piece that holds them.
Release CLI, SOLIDCRAFT_KERNEL=smlib: 405, 349 (72 and 90 degrees), 436, 1481, 723 and 725
pass. 1095 now gets past the planar regions; its extrusion of a plate with a cut-out
touching its edge at one point fails in SMLib's export ("a closed shell bounds two regions
and encloses one"). Every other sheet-metal case fails or passes as in rig-1, and 529

The five "boundary winds around the surface" refusals of the first SMLib rig run (solid.hole
1355, solid.revolve 1853, 1866 at 180°, 3191, 466) are one mechanism: a revolved face whose
profile ends on the axis (a drill point, a cone tip, a half slot about its centreline) has a
pole, and its two meridian edges meet there with pcurves half or a whole period apart in the
angle, the parameter the pole leaves free. The boundary unwrapped every step to the nearest
copy, so at the pole it moved the next meridian a period along (1866's quarter sphere: from π
to 2π instead of 0) or, where the pole closed the loop (3191: v from 1 back to 0), the closing
step did; the loop then drifted a whole period and the face was refused as winding.
The pcurves are exact and run on continuously, so nothing within an edge is unwrapped now.
Where one edge meets the next, a pcurve starting a whole period from where the previous one
ended is moved back by it, except in a direction the meeting point is a pole of: there the
two pcurves' own values are the ends of the boundary's run along the pole, which the split
poles then carry. Each loop starts at a node off every pole whose predecessor is off them too,
so seam::drift's nearest-copy closing step never crosses a pole. All five cases pass;
tessellation/ and sweeps/ otherwise as in the rig run (1856 and 3006 pass, slow under a
machine load of 190; 2552 hangs as before).

Owner's decision for strips whose rulings turn freely along their edge (a face's
normal along a free-form face, which was refused): the far edge is not the
offset curve but a B-spline the kernel defines, and the strip is exactly the
ruled surface between the edge and it.
The far curve has the edge's own degree, knots and weights (so the ruled NURBS
needs no knot merging); it runs from the strip's start corner to its end corner
(where the rulings at the edge's ends reach); its interior control points are
given (handles) or the least-squares solution of weighted terms, the
construction's parameters: closeness to the rulings' ends at the edge's
Greville abscissae (W_CLOSE), fairness by arc length (W_FAIR), each end leaving
along the chord to the other end (W_TANGENT, one small function), and at a joint
where the chain runs on smoothly with shared sides the first and second
derivatives by arc length matched to the neighbour's (W_JOIN), in one solve
along the chain, an exact neighbour's far edge matched as it is. Exact strips
are unchanged.
ruled_far_handles gives each free strip's default handles; ruled_surface_with
takes moved ones. The Ruled Surface feature saves them as `far` (per chain
edge, null for the default; pending format note ruled-far-handles), and
surface.ruled takes them as `far`.

history), on a cylinder whose wall's loop uses its seam twice.

uses, faces by the record's surfaces, vertices by the record's points, the mesher's own

solidcraft-smlib is a dependency of every build (it answers NotBuilt without
SMLib), so the SMLib sides of surfaces.rs and blend_smlib.rs no longer sit
behind cfg(feature = "smlib"), and their stub modules go; blend_smlib's tests
run in every build like the rest. This also uses offset_backend::thicken and
the smlib_sweeps curve conversions in builds without the feature, which left
them unused there.

The three refusals of the cornered controlled sweep become the owner's rules:
- an orientation direction turns the section about the corner's binormal like
any sweep, then turns it back about its normal to the direction's frame
evenly along the next run, as a twist (direction_offset: the turn between
the carried section and the direction law's section there);
- guide rails follow a path with corners when each rail has a corner of its
own at every corner of the path, in the plane halving it and by the same
turn about the same axis; the rails are cut there into each run's
(run_rails), anything else is refused with the corner named;
- round a closed path with corners the first run starts from the closing
mitre and the last ends on it; a twist is allowed where the profile maps
onto itself (closing_offset), an end scale is refused.
Each run's station count now follows its own turn, twist included.
solidcraft-smlib is a dependency in every build (it answers NotBuilt without
SMLib), so smlib_sweeps' imp is no longer behind the smlib feature and its
stubs and not_built go; polyhedron calls offset_backend in every build.

A sweep that twists or scales refused any path whose direction jumps by more
than 1e-3 rad, a branch on the path's shape. It now takes the corner model of
the plain sweep: each smooth run is swept through stations by the laws a smooth
path has (twist and scale running with the length along the whole path, each
run going on from the section the last ended with), and the runs meet at each
corner in a mitre. Turning with the path, each run goes on past its corners as
a prism of its section there (the laws hold still across the mitre: the two
runs' sections meet on the plane halving the corner only when both are the
corner's section) and is cut back to that plane, then turned through the
corner onto the next run; only moving along the path, the runs meet at the
corner's section. The mitre plane is one function for both (mitre_of).
Refused, with the reason, where a control has no meaning at a sharp corner: an
orientation direction (it turns the section by its own turn, not the corner's,
so the two runs' sections don't meet), guide rails (their sections jump where
the path turns), and a closed path with corners (a twist or scale keeps the
last section off the first).

Intersection::point started its Newton solve from the last point found (a Cell holding both
surfaces' parameters) when that landed near the leader, as truck took a hinted point. The
answer then depended on what was evaluated before, so CurveEval was not Sync, and the
clearance check, which shares a body's DistanceShape (its edges' CurveEvals) across worker
threads, did not compile; with threads it would also have made the result depend on their
interleaving. Each point is now solved from the leader's own point, the path the hint fell
back to, and the unused trace tolerance goes with the hint.

sheet_hole_cut chose by failure: a hole's drills were tried all at once and, if that was
refused, one by one; each drill was tried as a flat cut-out and, if that was refused (or
machined nothing), as a bore. Now the drill's geometry decides, one path each:
- SheetBody::drilled_panels: the panels a straight drill meets and how square it is to each
(|panel normal · axis|); a drill into a bend is refused, as before. add_bore uses it.
- sheet_drill: square across every panel it meets is Drill::Across (sheet_primitive_cut, a
cut-out or pocket of the flat pattern), along every one into a rim is Drill::Along
(sheet_bore_cut, a bore), meeting no sheet is None, and anything else (square to one panel
and along another, or at an angle) is refused with the angle message.
- The all-at-once pass (sheet_drill_cuts) passes its errors on; its None (the drills not all
square along one axis) still puts the model back and drills them one by one.
- sheet_bore_cut passes add_bore's refusal on instead of answering None.

The boss's post and ribs, the boss's hole, the snap fit's arm and the rest started a few
hundredths of their height inside the material (and the hole and the groove ran on as far

The kernel has no boolean retries now, nor their diagnostics
(capture_boolean_diagnostics, BooleanDiagnostics, BooleanStrategy), nor the near-coaxial
crescent (coaxial_overlap, coaxial_candidate, with_attempt_budget). What read them goes:
- doc: FeatureResult and the evaluation cache carry no boolean diagnostics, and no "Boolean
retry" warning; the saved model no longer writes them (an older file's are ignored);
- engine: timeline.inspect / feature inspection drop `boolean_diagnostics`; fuzz runs and
the CLI fuzz summary drop their retry counts;
- inspect.interference: each pair is the bodies' Intersect, measured; the near-coaxial
crescent, the by-piece intersection of bodies in several pieces and the unverified notes
go (the command's doc no longer lists near_coaxial);
- inspect.clearance: an overlap is the bodies' Intersect, measured near its region; the pin
tries, the cut-down copies of large bodies (clipped, narrowed), the union cross-check
(union_disagrees, contradicted) and the malformed-part check (plausible) go, and the
measure near the origin passes its move's error on.
Tests: the retry test and the unit tests of the deleted checks are removed; the barrel join
test (tests/boolean_diagnostics.rs, now tests/barrel_join.rs) keeps its geometry checks;
the pin-in-bushing test expects the filleted case measured; assertions on empty diagnostics
and on near_coaxial are dropped; the corpus fixtures lose the diagnostics key and the one
retry warning.

Before sewing, each edge of one input is split exactly (Brep::split_edges) at every vertex
of another input that lies on it within the stitch tolerance away from its own ends, so a
patch whose corner meets a body's edge part way (the five-plus-sided fill's midpoints)
sews with no T-junction. The pieces carry their edge's history. The search is the nearest
of 64 samples refined by golden section, over the vertices within a chord's reach of the
edge's samples. Nothing else in stitch changes.

Each piece keeps the edge's curve on a sub-interval, a new vertex sits on the curve at each
split, every use becomes uses of the pieces with its pcurve cut at the same parameters
(bspline::segment), wire edges likewise; the result is in canonical order with each
edge's source edge. What a sheet needs so that another's vertex on one of its edges is a
vertex of both.

part()'s walk becomes renumbered(): the record of given source regions in canonical order.
part() hands it the regions it cuts; canonical() hands it every region as it is, open,
wire and vertex shells included, for records builders put together in their own order.
Each edge's uses come from the walk; a source list naming exactly those uses keeps its
radial order (turned to start at the primary use), as part() did.

The strips keep their model (exact where the rulings move the edge by an affine
map, a ruled B-spline fitted within 1e-3 otherwise; mitred or rounded corners;
an inside corner cut back). Each strip is built on its own on the record: the
chain edge as its exact NURBS (a circle or ellipse arc rational quadratic), the
far edge its image (its control points mapped) or the fit's, the surface a plane
or the ruled NURBS between them with straight pcurves along its parameter lines.
A mitre's triangles are flat polygons; a round corner's sector is SMLib's revolve
of the incoming side about the corner's axis. The faces are stitched by SMLib
(surfaces::sheet_of, which now takes the operation's operands), each strip made
in place of its edge, each corner face in place of the two edges there. Tests
read the record; the check that the strips stand on the box's own edges now
looks for edges lying along them, as the result is a body of its own.

Only moving along the path, the runs meet as they are. Each wall keeps the

SMLib's boolean takes touching and coplanar faces exactly, so the tools no longer bend
around them, and no tool is tried a second way after a refusal:
- extend_for_coplanar / grow_profile_for_coplanar (a cut or join tool run on past faces it
lies on, its profile grown out of walls it touches), Surroundings and its clearance probe,
fill_void_holes (holes over empty space taken into the profile, #1360),
trim_embedded_join_ends (a join's buried ends cut off, #2059), the touching-face checks
(kernel::can_join_touching_faces / can_join_all_touching_faces) that decided when the
exact tool could go in, the profile that "grows wherever the samples find room" when the
build failed, region_samples, and the revolve's grown profiles;
- a tapered tool's run-on into the face it stands on (taper_run_on_fits, face_level_at) and
its straight TAPER_FOOT: the tapered tool is the profile drafted over its length;
- apply_traced's batched boolean that, when refused, put the model back and ran the tools
one by one (and common_join_target, which only it used): the tools run as the operation
always runs them;
- a pattern's copy of a reduced fillet tried again as a new fit when the copied radii were
refused: the copy uses the radii the original was built with;
- union_apart / join_apart errors are passed on instead of leaving the tools apart.
The command behaviour stays: the same tools, the same lineage, the same at-once boolean of
tools apart. The tests of the deleted growth and trimming (coplanar_growth_tests) go with
them.

general_fill takes loops of three to sixteen edges. quilt_body assembles fill_iso's
patches into one sheet: each loop edge whole, or for five or more its two halves at the
middle of its interval, both on the edge's exact curve record and sharing a midpoint
vertex; each spoke a new edge from that vertex to the centre; every pcurve the straight
line in (u, v) of its side. The history marks every face generated, each edge or half a
piece of the body's own edge, each spoke new. A reversed loop edge's knots keep the
interval's ends exactly, so pieces name the edge's own vertices.

A loop of N >= 5 edges is N four-sided patches about a centre point: each edge split at
the middle of its parameter interval, a spoke from each midpoint to the centre, patch k
on the second half of edge k-1, the first half of edge k and the two spokes beside them.
All patches share one compatible space, so each spoke is the same control points in both
patches it divides and the centre one point; the least-squares solve takes them once
and adds rows opposing the two patches' derivatives across each spoke (tangent there).
The one- and three-/four-sided fill is the one-patch case of the same model. The result
lists each patch's sides (edge pieces with their parameter ranges, or spokes) and the
spoke curves; every pcurve is a straight line in (u, v).

sketch.intersection_curve (LinkSource::Intersection, crates/doc/src/
project.rs) intersected the two bodies' display meshes triangle by triangle
and chained the segments into polylines: a curve known only as points, off
the true intersection by the meshes' chord.
kernel::meeting_edges(a, a_face, b, b_face, chord) takes each side whole or
as one face (that face alone as a surface body, surfaces::taken), tags both
and imprints the first by the second in SMLib (smlib_imprint: "each of its
faces that `tool` meets cut along the intersection", capi/include/smlib.h).
SMLib intersects the faces' surfaces and trims each curve to both faces, so
the edges the imprint makes are exactly where they meet; its own history
says which they are (an edge no edge of either operand became). Each comes
back as its record curve on its interval, from SMLib's export of the
imprinted body, with its points from that body's mesh at `chord`. Sides that
do not meet give none.
The intersection link now stores each edge as a wire with its exact curve
(Wire::exact, the existing WireCurve; no new type or format change), its
points at 1/1000 of the larger body. project3d::mesh_intersection, its
triangle/triangle test and segment chaining go; project3d::mesh_of becomes
part_of (the body and, for a face reference, the face index).
Needs in crates/kernel/src/lib.rs (the coordinator's): `mod intersection;`
and `pub use intersection::{MeetingEdge, meeting_edges};`.

Curve::RationalSpline (rational where a weight is not 1) and each UV curve
the method returned as a Curve2, with SMLib's type, deviation estimate and
the 3D curve's natural interval; ssi::intersect loses its sample count. A
curve SMLib does not hold as a B-spline is Error::Unsupported (it is never
approximated); a B-spline whose knot count is not points + degree + 1 is an
argument error.
The SSI corpus scorer (tests/ssi_corpus.rs) samples the exact curves itself
where the corpus runner samples them: 4001 parameters spread evenly over the
3D curve's natural interval and over each UV curve's interval, the surfaces
evaluated at the UV samples, samples that cannot be evaluated dropped. The

before. A rail lying in the last section's plane crosses it all along, first at
the far section, 100 mm from the bow's curve, and the loft was refused ("a guide
rail crosses section 2's plane"). A rail runs from the first section to the

uses, and SMLib joins the faces across them (Brep::merge_faces: each edge
removed where SmEdge::IsTopological finds the faces' surfaces coincide), so the
merged face is SMLib's and the history its own tags (Merged), composed through
the body's. SmBrep::Simplify is not this operation: it refits curves and

A tool is now a set of schema 4 record surfaces, each over a parameter box,
unbounded where the tool is: a plane; a face's surface over its own box; a
sketch curve as one patch per segment swept along the direction (a line a plane
strip, an arc swept square to its sketch a cylinder strip, any other segment its
exact rational Bezier extruded), an open curve continued along its end tangents
past the body. SMLib cuts the faces where the patches meet them
(Brep::split_faces: its intersection curves trimmed to each face by
MergeCurvesOnSurface) and slices a body with one patch (Brep::split_body); the
history is SMLib's own tags. Nothing is traced on a mesh, sampled or fitted.
Which side of the tool a point is on is its offset along the normal of the
nearest patch, each patch's surface prepared once with its projection grid
(ToolSide), never per point. ToolSide::of and side_of_point take the body the
tool must reach past; face_side becomes face_sides (every face of a body, one
mesh); analytic_field becomes analytic_face (a face of a body, on its record);
split_any returns the face map instead of the truck imprint. split_edges_at and

Seams and merged topology tell faces on one surface apart by the record's own surfaces
(offset::surf_of: plane, cylinder, sphere, cone, torus) and, for free-form faces, by the very
same surface record, never by fitting circles, spheres and cones to mesh vertices or by
comparing mesh normals along an edge. Edges are welded by their record vertices and middle
point, split lines and pinches read the record edge's points, a cone's apex is checked against
its faces' record vertices. The mesh still gives faces of no area and a cylinder face's extent
along its axis; a cylinder's side (hole or boss) is the record's.

planar_regions_boolean replaced each free-form loop (a font's curves, an ellipse) with arcs
fitted within PLANAR_FIT_TOL before its own line/arc arrangement, and a loop the operation
cut kept those arcs: a cut free-form outline was extruded inexactly. Now each operand is a
sheet of planar faces built from its loops' own curves (Brep::planar_faces; lines, arcs and
the Béziers and conics as NURBS, exactly) and SM_API's 2D boolean combines them
(Brep::boolean2d): SMLib's topology intersector, the one the solid booleans use, splits the
operands' edges where they cross and the result's edges are copies of those curves. The
faces read back exactly (prism_curve::projected: lines, arcs, each Bézier span as the
segment it is). The Rust arrangement (crossings, ray parity, chaining, the fit and the
"exact again" restoration) is deleted: one source, no fitting.
extrude_planar_regions unites its regions the same way (balanced unions of one-region
sheets) and refuses pieces of the union that share a vertex, read off the result's
topology instead of a line/arc crossing test on fitted arcs.
Signatures stay (doc/sheet.rs and mesh_convert call them as before); `tolerance` is the gap
a loop may close within and the least tolerance edges are read back at. PLANAR_FIT_TOL
stays for doc/engine's flat patterns, which fit their own loops. smlib_sweeps::curve (the
Seg2 to SMLib curve conversion) is made pub(crate) for the sheets.
Tests: those of the deleted helpers (crossings, ray parity, closest_param, segment boxes)
are gone; the free-form test now asserts what the exact boolean gives (the half-ellipse
notch is the ellipse's own conics, area exact to 1e-6; the joined ellipses are conics), and
the fitted-arc budget assertion is dropped. Without the smlib feature the booleans are
refused ("not supported yet").

edge, on its interval and run the loop's way, is a side, so its pcurve is a straight line

curvature from the surface's exact second derivatives. Corners whose neighbours' tangent

A sweep path through 3D sketch curves sampled every planar sketch curve in it
into a 0.01 mm polyline, and took every linked 3D curve as the points its link
stored, so SMLib got a many-cornered polyline (and refused a smooth one). Now:
- a planar sketch curve in such a path is its exact segments
(PathPiece::Segs of PathSeg::of_sketch over exact_segs);
- a linked curve whose source has an exact curve keeps it: Wire::exact holds
the record curves (WireCurve: schema 4 curve + interval) end to end along the
wire, set with the wire when the link is resolved: an included body edge its
record edge (kernel::brep_record), an included sketch curve leaving the plane
its segments (kernel::sketch_record_curve). Wire::map carries them with a
placement. The sweep follows them through kernel::curve_path (line, arc,
ellipse as rational quadratic spans, polyline, B-spline as Bézier spans).
- curves known only as points (projected onto a face, intersection and iso
curves: the link resolves them on the mesh) stay points.

PathSeg::Bezier(SpaceBezier) replaces PathSeg::Cubic: a rational Bézier span in

spans and an edge's own curve are one kind of segment, swept by SMLib as the
NURBS it is. SpaceBezier evaluates, differentiates (quotient rule on the
hodograph), measures and walks by length (Gauss-Legendre), reverses and maps.
edge_path gives a body edge's record curve as path segments exactly: a line,
an arc, an ellipse as rational quadratic spans, a polyline's lines, a B-spline
as its Bézier spans between knots (bspline::segment); an intersection curve
(no exact curve in the record) is refused. PathPiece::Segs carries such exact

extend_surface keeps its signature, options and error messages. One model:
SMLib extends the surface past a side of the face's parameter box
(smlib_extend_sheet, CreateExtendedSurface: natural continues the end spans,
tangent G1, curvature G2) and the face stays one face on it, tagged so the
face is Modified and its sides keep their edges. Several picked sides grow
the box on each. Up to a target, the face is extended 50 body sizes past
its edge and trimmed back with trim_keep (SMLib's exact intersection),
keeping the piece the face lies in. Back to the bounds is untrim of the
picked edge's face, in place, with its holes; one already there is
refused. A plane's straight edges with neighbours lengthened still go
through surfaces::extend. Edges are picked on the schema 4 record (samples
of each edge's curve), an edge two faces share or of a hole refused as before.
Not ported (every far edge there was a cubic fitted through marched
samples, which the exact-B-splines rule forbids): an edge that is not a
whole side of its surface's box (trimmed edges, curved planar edges such as
a disc's, a notch), mitred corners on such faces, sides run square to the
edge on a non-box face, and bodies of more than one face. These now answer
"not supported yet: ...". Tangent and curvature no longer add a separate
run-off face: SMLib's G1/G2 extension is one face (the engine's
surface.extend description says so).
Tests ported keeping their assertions: the planar extension, the cylinder

The faces' descriptions become a record with exactly the topology they give: vertices
and edges shared by key (lines, circles or flat arcs as their exact rational quadratic,
Bezier chains as B-splines), planes about the boundary's mean, revolved lines as
cylinders, cones or planes, extruded arcs as cylinders, ruled walls as B-splines with
exact iso-line pcurves. assemble() groups faces into shells, puts closed shells in
regions (a cavity where the outward normals enclose negative volume, in the solid whose

SMLib imports the record as trusted; the body and the face each body face came from
follow SMLib's order. The edge-sheet and vertex-fan logic for touching bodies is kept.

heal: a body's faces on one surface merged and its edges on one curve joined by SMLib
(Brep::merge_faces, SmBrep::RemoveTopologicalEdgesAndVertices), the edges along its split lines
kept, with SMLib's history over the body. Its booleans already end the same way
(SmMerge::BooleanPostProcess). The truck healing is deleted with what only it did: coplanar and
collinear merges by hand, flat surfaces rebuilt as planes, and approximate edges refitted as
lines or arcs from samples. on_split_line stays; edge_points reads a record edge.
Deleted, with no port: the retries around the old boolean's failures (touching_walls,
bore_guard, tangent_cylinders, sphere_lens, tool_reseam, candidate_reach). Each re-ran a failed
boolean with a changed tool or split faces; SMLib's boolean is the one path, and a case it
fails is its defect to fix there. Their own tests go with them (the helpers' unit tests in
issue_788_tests, bore_union_tests, candidate_reach_tests, and sphere_lens' relaxed-tool test);
the #2750 lens cut's result test stays, as a boolean test, without the retry diagnostics.
Heal's tests built truck prisms and a truck spline edge: deleted.

The neighbours of the deleted faces are rebuilt from the body's record: each keeps its own
plane (every moved corner lies on it) and its edges away from the gap; corners on the gap move
to where the neighbouring planes meet, and the gap closes with straight edges shared between
the rebuilt faces. Moved and restored edges are recorded as pieces of the edges they replace
(assemble.rs: Assembly::piece), so the history is as before: untouched faces kept, neighbours
modified, edges kept, pieces of their edges, or where their faces meet.
Test deleted: delete_pocket_keeps_an_imported_face_around_it bowed the edges of a truck body in
place to show that a face losing only whole loops keeps its surface; a record body has no such
in-place edit, and every rebuilt face now keeps its own surface.

The band is built on the body's record: the face keeps its other loop and the band's edge, the
walls rise along the face's loop (continuing the walls below) and along the band's edge
(planes along lines, cylinders along arcs), and the band's top is the face's plane moved up.
Each face is given with its outside, so no orientation is tried: the eight flips the old

The emboss is built from the body's record: the wall's face loses the profiles' footprints,
each profile adds planar walls and its cap on the wall's cylinder at the new radius, and SMLib
builds the body from the finished record (assemble.rs: a record taken apart and finished again
in canonical order, pcurves from the record's routine for new uses, the record's own for kept
ones). surf_of and with_same_surface read the record's analytic surfaces; the topological
offset and draft that only the old kernel used are deleted (SMLib's offset faces and draft in
offset_backend replace them).
#3782: the saved pick had to lie on the half of the wall the sketch is tangent to (its angle
inside that face's span). The wall is every exterior cylindrical face of the body (a stepped or
interrupted cylinder is refused before), so the pick is checked on the cylinder between the
endcaps. The sleeve test's far-side pick now succeeds; a pick on the bore is still refused.

The fork's shims now hold an operation SMLib reports done to having done
something (SMLIB_ERR_NO_EFFECT, -1107: a blend that made no face, a face
move or draft that moved no face). It maps to Error::NoEffect, and the

The fork pin moves to 6bb2938: the chamfer side fix of the piecewise

faceted_boolean (a body with a closed triangle mesh) faceted the body's curved faces and ran
its own BSP polygon boolean, then rebuilt a truck solid. It now builds the mesh into a
solid: each run of coplanar triangles sharing edges (corners within `tol` of each other's
planes) one planar face, its boundary chained into loops (split where a loop passes a vertex
twice, holes given to the innermost outer loop), sewn with sew_touching; SMLib's boolean
takes it with the body, whose faces stay exact. The history over [a, mesh] is the boolean's
over [a, tool] with the tool's own over the mesh substituted: each tool face from its
triangles, each tool edge the meeting of the runs either side.
Deleted with the BSP and the rebuild: planar_boolean and sliced_planar_boolean (the truck
boolean's exact fallback for touching planar faces: on SMLib the boolean is one path),

The prism module kept two things: the 2D arrangement of planar regions
(planar_regions_boolean, and extrude_planar_regions, which normalises the material with it,
proves the pieces apart and extrudes them with crate::extrude, SMLib's extrusion with its
face sources), and a second route to the solid boolean: prism operands read section by
section, the result sewn and its history rebuilt from section tags (prism_boolean,
prism_union_between_caps, the stacked and free-form variants, prism_lineage.rs) and the
column-local variant (prism_local.rs). On SMLib a boolean is smlib_boolean, with SMLib's
own history: the second route is deleted, with its tests (prism_spline_tests.rs, the
stack/prism tests in planar_tests) of what no longer exists.
The section tags shrink to what the arrangement uses: the free-form segment a fitted arc
stands for. wall_along reads a record surface (cylinder, revolved line, spline net) for

measure_backend asked SMLib for mass properties at 1e-8, the finest its
integrator allows and below the range SmApiBrepComputeMassProperties
documents ("Relative accuracy, clamped to [1e-4, 1e-1]", SmApiQueries.h,
whose cost is "governed by dRelativeAccuracy"). The tight request was there
because the documented range did not hold on faces bounded by circles
(KNOWN_ISSUES.md); the fork's dcbb07d integrates each trim-curve knot span
on its own, and such faces now meet it (a cylinder's volume 1.8e-6 off at
1e-4). At 1e-8 SMLib's measure was most of the regression rig's time on a
modelled thread (threads/602).
The measure now asks 1e-4: ten times inside the 1e-3 it is held to (AGREE
against the mesh measure, and the rig's volume and area tolerance). NURBS
spheres and tori can still miss 1e-4 by a small factor (tangency-labs/
solidcore#384; a torus's volume 2.5e-4 at 1e-4), inside that 1e-3.

straight edge, edge tangents at the ends. It now runs before SMLib, so a blend that runs
past its faces is TooLarge with the largest size that fits (fillet_max_each, the taper

fillet_max_each groups the edges by their faces and ends in the record. fillet_g2_corners

With no targets picked, an extrude's Join, Cut or Intersect changed every body
of the active component it met, shown or hidden: a hidden coincident copy was
joined in and disappeared. Where some bodies of the active component are
hidden, the shown ones become the feature's participants, kept with it, so
showing or hiding bodies later doesn't change the model. Explicit targets and
participants, and a face's or a face sketch's own body, still win.
Test: the issue's plate with a hidden copy and a rim joined on.
Main reached the same fix for Cut and Intersect in #3961 (its targets-based

Three defects in restating trimmed surfaces (144/143) as STEP, kernel-agnostic:
- A boundary loop is one closed curve (IGES 5.3 composite curve: each piece ends
where the next starts), but each piece's ends were sewn into vertices by
distance alone, so pieces that miss by more than the sewing tolerance left the
loop open and the face was dropped (#3845). Surfaces are now read first and sewn
after: every meeting point of two pieces is one vertex (union of the two), the
STEP reader then carries the distance as the vertex's tolerance.
- With no parameter-space curve to give the start, a composite whose first piece is
written end to start kept that direction, so the second piece did not connect
(#3913). The first piece now runs from its end away from the second.
- All sewn surfaces were written as one shell, so two separate closed boxes came in
as one body of two shells that SMLib's check refuses (#3972). Each connected set
of faces is now its own shell and body (Body1, Body2, ...); a shell writes only
the vertices its edges use, in the sewer's order.

EvalSurface::wrap asked uv::closed whether a spline closes on itself every
time it evaluated a point outside the knot interval, and that test walks the
whole control net (its extent, then the first and last rows). A tessellation
of a closed spline unwraps its parameters across the seam, so about half its
evaluations are outside: on a coil's helical tube (thousands of control
points) the test was 80% of the tessellation's time, 30 s of the coil
command on SMLib (sweeps/3832, sweeps/793).
EvalSurface::Nurbs now carries `closed`, set by EvalSurface::nurbs from the
same test; wrap and uv::domain read it. An affine map of the surface keeps it
(closedness does not change under one). The answers are the same as before. The constructor's callers in
crates/kernel/src/tess (size.rs, surface.rs) change with it.

The tests in tess/ build their bodies as before and plan crate::brep_record of them; the
assertions stay. Changed where what they compared is gone:
- surface.rs: each face evaluates through eval_surface and its record-parameter map as the
record's own evaluator (SurfaceEval) evaluates it, point and natural normal over the face's
box (was: as truck evaluates it); the kinds counted are the record's (planes and analytic
surfaces; SMLib's primitives have no spline faces, which truck's sphere was).
- edges.rs: edges are the record's; the intersection-node test becomes: every edge between two
curved faces puts each node, through each face's pcurve at the node's curve parameter, on that
face's surface at the node, within the edge's tolerance (was: Newton's per-node parameters
within 1e-7, which tess/ssi.rs no longer computes).
- tests.rs: "reference mesher" comparisons are against Body::mesh (the same mesher on the same
record, at a finer tolerance for the cross-hole volume). Removed the assertion that
seam::turns_more_than_once finds the thread's winding walls: that test of which mesher to use
no longer exists.

Each edge node keeps its curve parameter; each face reads its nodes' parameters from its own
pcurve of the edge at that parameter, so nothing on the boundary is projected and a seam's two
uses (each with its pcurve) are its two sides: the cases the projection could not tell apart
("boundary winds around the surface", sides that cross where projection snapped them, poles).
The record's (u, v) go to the evaluator's in closed form (tess::surface::Params): the same for
planes, splines and revolutions; (θ, v) to (−v, θ) on a cylinder's or cone's generator; on a
sphere or torus (θ, φ) to (1 − s(φ), θ), s the rational meridian's parameter, from
tan(φ'/2) running linearly over each span (φ' from the span's middle).
A pcurve that does not cover its edge's interval, or places a node farther from the edge than
ten times the chord tolerance plus the edge's own tolerance, is an error naming the face and the
edge: the record is wrong there (for an analytic face, a trim left in SMLib's internal NURBS
parameters rather than the record's would show here).

A drawn 3D spline reached the kernel only as its sampled polyline (Wire.pts), so SMLib refused
to sweep along it ("not supported yet: SMLib sweep along a smooth path of points"). The doc
holds the spline's fit points; the curve is the centripetal Catmull-Rom spline that
fit_polyline samples. Each span of it is a cubic (Barry-Goldman), and its derivative at a fit
point depends only on that point, its neighbours and the two knot intervals, so neighbouring
spans share it: the spline is exactly one cubic Bézier per span, C1 across the spans.
- geom: catmull_rom holds the curve: samples() (fit_polyline's arithmetic, moved verbatim;
sketch::fit_polyline now calls it) and beziers(), the exact spans; ArcLength on CurveN
(Gauss-Legendre per knot span, Newton for the parameter at a length).
- kernel: PathSeg::Cubic, a cubic Bézier in space (the 3D counterpart of PathSeg::Curve, which
is planar), with its arms wherever PathSeg is matched (start/end, tangents, length, point at
a length, turn, SMLib curve as a degree-3 NURBS, halving). PointPath / PathPiece carry a path
through 3D sketch curves: polylines as points, drawn splines as their fit points (reversed
when the path runs them backwards); PointPath::segs gives SMLib the spans and the lines;
sweep_point_path_with sweeps it (SMLib through sweep_with, so corners, twist, scale, rails and
orientation take the existing routes). A smooth polyline piece (a projected or linked curve,
which the kernel only has as points) is still refused on SMLib.
- doc: path_points builds the PointPath (a wire with three or more fit points is a spline
piece); solid sweep and pipe call sweep_point_path_with; rails, surface sweeps and curve
networks take its points as before.
Checked in scratch (not committed): the spans pass through every fit point and every
fit_polyline sample at its parameter (1e-12), C1 at the joints and round a closed spline;
samples() is bit-identical to the old fit_polyline over 1180 random open and closed inputs;
SMLib sweeps of a radius-2 circle along an open spline and round a closed one match
pi r^2 L (L by independent quadrature of the curve's definition) to 1e-7 and 3e-8.
sketch/wire.rs: the existing closed-spline test reads SPAN_SAMPLES from its new home.

A Join with one target takes every tool, whichever it meets, but it grew the
target by one tool at a time: each union took the whole result so far, and
each step first meshed it to see whether the tool met it (which with one
target decides nothing). n tools cost n^2 in every per-body step of a
boolean (converting the operands, checking the result, exporting it back),
whichever kernel runs it: a combine of 64 separate pegs (booleans/3455) took
400 s on SMLib, of 36 lofted blades and a disk (crashes/2992, sweeps/1856)
485 s and 97 s.
With one target, the target and the tools are now unioned pairwise, level by
level, so each body takes part in about log2(n) unions. The result is the
same union under the target's name, with the lineage of every union. Several
targets keep the absorption order they need. The doc and engine join and
combine tests passed and failed on SMLib as before (measured before the
rebase).

uv::project, given no hint that converges within `accept`, evaluated a grid
of up to 16384 points of the whole surface for every point it placed, then
sorted all of them by distance. The grid is the same for every point of a
surface, and a face's pcurves place hundreds of points on one surface: on a
modelled thread's helical faces that grid was most of a boolean's time on
SMLib, in the operands' records, SMLib's export of each body and the
result's (threads/2526, the ladder's threads).
uv::Starts keeps the grid, filled on first use; uv::project_with takes it,
and a face's pcurve fit (pcurve::On) keeps one per face. The 32 nearest
starts are picked with a partial select instead of a full sort, in the same
order (nearest first, grid order where equally near), so every point gets
the parameters it got before. (The tessellation's boundary projection can
take the same grid; crates/kernel/src/tess is the mesh agent's.)

On a B-spline face the export now takes each edgeuse's UV trim exactly as
SMLib holds it (EDGEUSE_NURBS_*): the face's parameters are SMLib's, so the
trim is the pcurve, reversed exactly (knots t -> a + b - t) where the
edgeuse runs against its edge, its knots mapped onto the edge record's
parameter where that is an affine image of SMLib's (identity for spline
edges, as_line's map for NURBS lines, the C side's map for lines), and its
end knots set to the edge interval where they differ by rounding (within
the schema's 1e-9 slack, else an error). Changed: export.rs `curves`
(per-edge TrimMap), new `trims`, `mapped`, `Face::given`,
`Edge::trim_map`, the face loop in `native_ordered`, `pcurves`,
`outer_area`.
Analytic faces and circle/ellipse edges keep brep::pcurve: SMLib keeps an
analytic face's trims on its internal rational B-spline (SmCylinder.h:
"the map from one to the other is not linear") and a circle's on its NURBS
parameter, neither an exact B-spline in the record's angle parameters.
brep::pcurve::EdgeUse gains `given`, a producer's exact pcurve taken as it
is (structure and interval checked, moved by whole periods with its loop,
never refitted). Existing construction sites (STEP reader, tests, truck
adapter) pass `given: None`; the existing tests change only for the new
field.

tess::plan takes a brep::Brep: faces, loops, shells' face sides and edges in the record's
order. Surfaces go to the evaluator's form from the record (planes, splines and revolutions
through SurfaceEval; a cylinder, cone, sphere or torus as the exact revolution of its line or
rational-arc generator about its axis). Edges are sampled on the record's own curve evaluator
(CurveEval), an intersection curve included, so tess/ssi.rs and the per-node parameters it
carried are gone; every boundary node's parameters come from projection.
No fallback is left in the planner's path: a curve that does not evaluate on its interval is
an error naming the edge (it was a two-point chord, or truck's evaluation); a surface the
evaluator cannot express an error naming the face and its kind. Errors name the face, its
surface kind and, for a node off the surface, the loop, node and point. The module doc states
the order: a cheaper layout where the face suits one, else constrained Delaunay in (u, v),
else an error.
MAX_ANGLE_BOUNDARY and MAX_RELAX are tess::size's own. Removed with truck: the winding test
and pole-to-pole seam test that chose between this planner and truck's mesher, and
boundaries_on_surfaces (truck blends). The tests in tess/ still build truck bodies and are
left for the record-based Body.

Through SMLib, in place of "not supported yet":
- A sweep along a path with corners: each smooth run swept on its own and
the runs joined at each corner in a mitre (each run swept on straight past
the corner and cut back to the plane halving it, where the next meets it
face to face), including the corner where a closed path closes; only
moving along the path, the runs meet on the profile. History: walls from
their segments (found half-way along each run), caps where the path ends.
- A free-form path curve (a spline's Bézier pieces, conics) reaches the
kernel as PathSeg::Curve, its exact piece, instead of the sketch's
polyline of lines: SMLib sweeps along the curve itself; truck's sweeps
flatten it as before (now the piece's own polyline within 0.01 mm, which
turns ladder 04/004 into a pass for truck too). Patterns along a path
flatten it and measure as before. A sweep that twists, scales or follows
rails places its stations by length along the curve.
(Such a controlled sweep still refuses a path with corners.)
- A loft through sections with holes: each section's outline and holes are
one SMLib profile, the holes matched as for truck.
- A loft to a point: SMLib's pyramid (smlib_loft_to_point).
- A draft extrusion with a straight foot: the foot's prism and the drafted
part (sloping from the foot's top to the far end the taper gives) joined
face to face; each segment names its foot and its sloping wall.

sweep along a straight path is an extrusion and one turning with arcs about
one axis a revolution (exact walls), and a sweep round a closed path closes
its walls on each other, without caps.

The case's own method says one body with an inner shell (the void of
radius 18.5 inside the ball of radius 40), but without a "shells" entry
the rig asks one shell per body. It now asks two, as the method derives.
SMLib still fails the case on its volume: 294558 mm3, near the sum of
the two balls (294604) rather than their difference (241561), so the
inner shell is not taken as a void.

again in the offset's merge (rig shell/3103, a two-half cone frustum
shelled open at the top, now one valid solid at the closed-form
volume).
- ffaf4e8: an intersection edge's end goes to its own vertex when its
ProtoVertex resolved into several (rig fillets/1488, the slab joined

On SMLib a sweep with a twist, an end scale, an orientation direction
or guide rails, and a loft with guide rails, were refused. They now
place the profile at stations by the laws the kernel already defines
for them (sweep_path::controlled_stations / railed_stations, and the
loft_rails law: plain loft between the sections moved onto the rails),
each section the profile's exact image, and SMLib skins the walls
through them (Brep::sweep_stations, Brep::loft). The path is sampled
exactly on its lines and arcs, a station per degree of turn: SMLib's
skin interpolates with free ends, its error falling as the square of
the step (a quarter-twisted square is 2e-7 off in volume at 1.4
degrees, 2e-6 at 2.8). Round a closed path the last section has to
land on the first (closing_offset, as for truck) and the ends are
joined. A railed loft needs each section's curves to pair with the
others' (same kind), else "not supported yet".
A path of points (3D sketch curves) was refused outright on SMLib; a
line or a polyline with corners is now swept as its lines (the
corner refusal still applies), and only a smooth polyline of more
points (a drawn 3D spline) stays "not supported yet".
History in the builders' vocabulary: caps from the start and end
section planes, walls from the profile segments (round a closed path,
from points inside the walls at the middle station).

thinner than the wall (#397), nested shells imported in any order (#388) and

zero inside the edge is refused; the split coil's halves now measure within

The kernel accepts `truck` (as well as unset) for its truck backend, and

A face's grid lines are thinned to MAX_FACE_GRID points (and now to at most that, where the
rounding of thin() could leave it a little over), but the cut grid adds the face's motorcycle
traces to them and then refused when its cells came out over the cap. The face fell through to
Delaunay, whose refinement budget a face of that size is far past: a split coil's wall at the
measuring tolerance got 90 000 triangles where it needs 320 000, and the halves of #793's coil
measured 1.5% short of the whole. The cut grid now thins its full lines (the same evenly spaced
choice as the face's grid, moved into grid.rs) until the cells fit.

SMLib writes a modelled thread's groove walls as splines winding once per pitch, and splits the
bore or shaft into one face per turn, so no face of revolution has a loop turning more than once
and turns_more_than_once missed the body. Truck's mesher then took the winding walls: meshes
reaching 1.4 mm past the block (#1995, #2526, #3311, ladder 06/004), volumes of -1.8e7 and boxes
120 m wide (#2038 join, ladder 06/003), or spade's "!previous_region.is_empty()" assertion inside
its constrained triangulation (#3952, ladder 06/001, 06/002). A spline face now has an axis too:
the mean binormal of an iso-line that winds more than once about it, through the iso-line's
centre; a boundary loop turning more than once about that axis routes the body to the display
plan, as a helical trim on a cylinder already did.
Truck's own coils (sweep_helix's spline walls) go the same way; their walls are longer than a
grid's 1024 lines resolve at the measuring tolerance (three turns of a 20 mm coil need ~1200),
so a direction may now have 8192, the grid as a whole still capped at MAX_FACE_GRID.

A thread's root band that runs out through an end face (a strip a quarter pitch wide winding
ten turns, ending obliquely, so it has no four corners to blend) fell through to the butterfly
of a round face. Its cuts ran lengthwise through the strip, seeded the whole way: ~200 000
points whose triangles zigzagged along the band, six times its area and up to 1.6x the chord
tolerance off the surface. A curved face whose division across one parameter has no inner line
(straight and within a side there) and with no room for a lattice seed now skips the patch and
cut-grid layouts and goes straight to Delaunay of its boundary nodes with sag refinement:
11 600 triangles for the whole part instead of 438 000, within the tolerance, the triangles'
area matching the surface's. A fillet narrower than a side but curved across keeps its layouts
(Delaunay from its boundary alone runs out of refinement budget at fine tolerances).
cdt::has_room tells "no seed fits" apart from "the lattice is too large to look through".

Each loop of a face is projected on its own, so along a closed direction a
hole can come out a whole period away from the outer loop. A revolved
dome (rational spline closed in v, bounded by its rim, its seam both ways
and the pole) has its outer loop opened at the pole into v in [-1, 0],
while a hole cut by a ball next to the seam projected into [0, 1]: the
triangulation covered the hole as well, and the cut measured 48118.36 mm³

On a thread's root band (1.4 mm tall at a pitch of 1.5) a point on the band's lower rim lies
0.1 mm from the rim of the turn below. The search's starts are dense across the band and
sparse along it, so its four nearest starts all lay on the turn below, Gauss-Newton settled
there, and the pcurve fit refused the edge ("the curve at 0 lies 0.1008 mm off the surface",
ladder/06-threads/007). The search now goes on through the nearest 32 starts until one
converges within the accepted distance, and stops at the first that does.
The test strips now put their knots at other angles on each turn (7.3 control points a
turn), as SMLib's screw sweeps do.

SMLib's intersection curves carry knots of full multiplicity where the curve is in fact
differentiable (its derivative the same either side). The pcurve fit took every such knot
for a corner and fitted the two sides apart; on a thread's flank, whose u runs hundreds of
times as fast as its v, the pieces met at up to 1.4 deg in (u, v), and SMLib's check refused
the record read back (Test #7 Bad CurveKink, offset 0.9997 against cos 1 deg).
A knot that leaves a spline only continuous by its multiplicity now gets a cubic with a
tangent there when the spline's one-sided derivatives (EvalCurve::sides) agree within 1e-9
of their size. Knots where the curve does turn are corners as before.

A thread cut by SMLib's screw sweep leaves flanks that are cubic splines of hundreds of knot
spans along the helix (an M6 through 20 mm: about twenty turns over u in [0, 1]). With no
hint (an edge's first sample), the projection started from a 17 x 17 grid over the parameter
box: one start every turn and a quarter, so the nearest starts lay on the turns beside the
point's own, Gauss-Newton settled there, and the pcurve fit gave up with "the curve at 0
lies 0.87 mm off the surface" (pitch x cos 30 deg, the next turn's flank). Every modelled
thread failed its export that way.
The search now starts, along each direction where the surface has its own knots (a
spline's, a revolution's profile's), from each knot span's start and two points inside it as
well as the 16 even steps, capped at 16384 points of the surface, so every turn is searched.

Without the native feature nothing reads a sweep's curve list, and clippy -D warnings
refused its two fields as dead code. The list is built through List::new in both builds;
only the native build keeps the slices the C API reads.

SMLIB_REV moves from e1ac3c3 to capi-solidcraft 276b509: thread groove
booleans (#435, #410), a holed profile swept along a bent path (#411), a
revolution a turn past its range (#428), shell and offset faces (#402, #380,
#403), the check linear in the body (#431), a far box that leaked (#377),
fillets and chamfers where a neighbouring round collapses (#416, #417, #420,
#379), tangent faces round a non-manifold edge (#383) and split faces of an
exact NURBS surface (#387).
The last one is why the SMLib block-and-cylinder decode test no longer finds a
spline edge on part of its curve: SMLib keeps a split face's parameterization
now. The test keeps its volume check; the decode of such edges stays covered
by spline_edges_on_part_of_their_curve_load_as_that_piece.

An SMLib result where one shell uses an edge four or more times (a hole tangent to the outline,
touching holes, stepped cuts touching along a line) was refused as "not supported yet: a solid
touching itself along an edge". The export now reads SMLib's radial order round each edge
(EDGEUSE_NEXT_RADIAL, EDGEUSE_RADIAL_ENTRY) and the side of each face its material is on, and
gives each pair of faces across one sector its own copy of the edge: the pairs across material,
so the surface is cut apart round each wedge of material, unless one face would get two copies
(a face on both sides of the line), which SMLib's check refuses as coincident edges (tests 33,
34); then the pairs across the empty sectors, so that face keeps one edge on both sides, as
SMLib's crack edges do. The vertices at the ends stay shared: copies would give a face passing
the point twice two coincident vertices, which SMLib refuses too (test 32). Geometry unchanged;
each copy keeps its edge's tolerance and history (Order.pieces). The radial arrays are checked
as hostile input (in range, cycles on their own edge).
Tests: a hole tangent to a block's outline exports with the line copied once per wedge (each
copy joining faces on one side of it), every edge two uses, and goes back into SMLib valid at
the same volume; a blind hole tangent to a side leaves the side a crack; through SMLib both come
back as one solid with verified history and empty validity.

After a parameter edit, a feature's stored face point is moved onto the
face its name finds. That used the face's nearest point to the old pick,
which lies on the face's boundary whenever the pick no longer lies on the
face: a shell opened at the end of a bar picked (150,15,10), on the edge
it shares with the bottom face, so truck opened the wrong face and SMLib
refused the pick (#2531).
FaceHit::pick_point keeps the point where it still lies on the face clear
of its edges, and otherwise takes the face's nearest point among points at
least a margin inside its triangles (a few pick tolerances, capped at half
the roomiest triangle's inradius on narrow faces).

With SOLIDCRAFT_KERNEL=smlib, kernel::draft hands the picked faces (a point inside each,
from the face under each pick) to Brep::draft, with SMLib's own history: the tilted faces are
the faces themselves (Modified). Faces SMLib can't draft (a round wall, a face not parallel to
the pull) are "not supported yet", never truck. Tested in modify_history_tests: a 40 x 30 x 20
block's side at 5 degrees removes 20 x 20 tan 5 deg / 2 x 30, with its history checked against
the geometry.

Flat faces tilted by an angle about the line where each meets a neutral plane, leaning in along

A face on a B-spline surface whose first and last control columns are the
same (closed around u), bounded by loops that go once around without a seam
edge, was refused ("a loop across a closed spline surface's seam"). It now
gets a seam as cylinders and cones do, along the surface's own boundary
column (u at the start of its knots, an exact iso-curve of the net), each
loop split where it crosses that column when it has no vertex on it; the
period is the knots' width. At a pole a loop may jump across u, where the
seam's two uses meet a period apart.
The step-conformance NURBS cylinder, dome and torus ring now read. With
SOLIDCRAFT_KERNEL=smlib all 17 parts import into SMLib with their exact
volumes and face counts. A spline closed in v only, or both ways, is still
refused.

A gap the boolean fixed on one side only left the freed edge in its common-edge map, and the next

SMLib leaves a corner patch where blends meet untagged, and blends() matches no single edge to
it, so it had no origin, and the edges between two blend faces (two chamfers' mitre) none
either. The history checks refused both (modify_history_tests' corner, whole-box and mitre
cases on SMLib). Now a patch without origin is made in place of all the edges of the blend
faces beside it, as truck records a corner, and every edge of a face new to the blend is where
its two faces meet.
modify_history_tests with SOLIDCRAFT_KERNEL=smlib: the three blend cases pass (28 of 30; the
painted shell and the painted box cut's pieces are the shell's and boolean's). Truck: 30 of 30.

With SOLIDCRAFT_KERNEL=smlib, chamfer_sides (two distances, or a distance and an angle) runs
SMLib's new unequal chamfer instead of being refused: `d1` back along the face facing up most
(down most with `flip`, as truck's chamfer_sides picks its first face), the other side by the
distance or angle, with the body's history as for the other blends. A radius law SMLib refuses
as having a corner is "not supported yet", never truck's round.
Tests (with the feature): 5 and 2 on a cube edge either way round (the top face keeps 15 or 18
of its 20, the chamfer face comes from the edge), 5 at 45 degrees, and the corner law refused.

Brep::chamfer_sides reaches the fork's smlib_chamfer_sides: `distance` back along the face
whose outward normal leans most along a given direction, the other side by a second distance
(ChamferSecond::Distance) or at an angle to the first face (ChamferSecond::Angle). The fork's
smlib_fillet_variable refuses a radius law with a corner with SMLIB_ERR_UNSUPPORTED, which the
crate reads as Error::Unsupported ("not supported yet"): SMLib's section fit ran smoothly
across the corner and missed the law (4 -> 2 -> 4 on a 20 mm edge took 35.1 mm3 for 40.1;
tangency-labs/solidcore#430). Both are in the fork at the pinned bf7c272.
Tests (ops_tests.rs), against analytic values: 5 and 2 either way round (the centroid tells
which face took the 5), 5 at 30 degrees, rejected arguments; a quadratic law 4, 1, 4 and a law
down to zero (1e-5), the corner law refused and the same points joined C1 built.

With SOLIDCRAFT_KERNEL=smlib, kernel::measure and measure_mass take volume, area and centroid
from SMLib's Brep::mass_properties (integrated on the exact surfaces, accuracy 1e-8). The mesh
measure is still made, as an independent check. Where SMLib disagrees with it beyond the mesh's
own accuracy (1e-3; tangency-labs/solidcore#384), or can't take the body, the mesh measure
stands and the measurement says why. BodyMeasure and MassMeasure carry `measured_by` (smlib |
mesh) and `notes`, and inspect.measure shows both. The box and topology counts stay the mesh's.

SMLib's tolerance update now fixes the vertex gaps its check reports (gaps over half a vertex's
tolerance), and every boolean, blend, shell, offset and sweep result grows its vertex and edge
tolerances over gaps below SMLib's own rounding bound before it is handed out. A thread's groove
cut from a shaft no longer fails SMLib's check on vertex gaps of about 1e-5 mm, and an offset
sphere face no longer fails it on an edge gap of 5.015e-6 against 5e-6 (shell/2939).
Also carries the fork's blend commits since ca2559f (second offset per edge, two-setback
chamfers, variable radius laws with a corner refused) and the IGES knot check.

Where two edge uses of a loop meet at a pole (meridians of a sphere), the periodic parameter's
jump there is free, and the pcurves took whichever jump made the loop counter-clockwise. Two
meridians a three-quarter turn apart bound a quarter of the sphere or three quarters of it, and
the loop alone can't tell which: a half disc revolved 270 degrees on SMLib came back as a quarter
ball turned inside out (sweeps/2667, V = -226 against 678.6).
pcurve::pcurves_within takes the face's parameter box, as SMLib gives it, and picks the jumps
whose extent in that parameter is nearest the box's; pcurves is unchanged.

Each solid item of a STEP file goes through the schema 4 reader
(solidcraft_step::topology, at the file's units and uncertainty) into
SMLib through the flat converter, healed where SMLib's check refuses it,
and comes back as a kernel body; its faces keep the file faces they came
from. A solid the reader or SMLib refuses is not imported, with the
reason: there is no truck fallback on this path. truck's own reader is
unchanged and stays the default.
Test: the 17 step-conformance parts read into SMLib with their exact
volumes and face counts, every face traced to an ADVANCED_FACE; the three
NURBS parts stay refused by the reader (a loop across a closed spline
surface's seam), as on schema 4 today.

smlib_record_ordered is smlib_body_ordered for a record of any origin (a
STEP file's, not only a body's): SMLib's body of it, healed where SMLib's
check refuses it as given, with where each of SMLib's faces and edges is in
the record's order. A record SMLib refuses outright now goes through the
healer too before the import gives up.

Schema 4 lets a circle or ellipse edge run up to one turn past its seam
(a quarter arc after the seam is [2π, 2.5π]); SMLib's circles take angles
within [-2π, 2π], and the flat import refused the whole body as invalid
input. The mapping now gives SMLib the same arc a whole turn back, and moves
the edge's pcurves on B-spline faces by the same amount, since their
parameter is the edge's. step-conformance's plate_100_holes now imports.

Solid::face_origin lists the ADVANCED_FACE or FACE_SURFACE entity of each

169 rig and ladder cases on both kernels, graded against each case's own answer: where SMLib
fails, grouped by what goes wrong (wrong geometry, a crash, the thread groove's boolean failing
SMLib's check, shell refusals, sweeps with no SMLib path yet).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
SolidCraft's own record of a body SMLib made (the rig's record check, the saved body, the next
SMLib import) re-fitted every pcurve at the kernel's working tolerance, 1e-5 mm. SMLib's fillet
and chamfer surfaces lie some 2e-5 to 2e-4 mm off their faces, so 15 fillet and chamfer cases
failed that check although SMLib's own passed. And SMLib reported one tolerance for a whole body,
the largest any part of it needed, so one loose edge (a pocket cut left one at 0.23 mm) made the
whole body loose on its way back into SMLib.
Now the tolerances go per edge and per vertex, both ways:
- solidcraft-smlib reads and writes the fork's new SMLIB_FLAT_EDGE_TOLERANCE and
VERTEX_TOLERANCE arrays. Export gives each edge and vertex record its own (never below the
floor, which becomes the body's). Where those understate what an approximated edge needs on
its face (SMLib holds a blend's end curve 2.3e-5 mm off its plane at 2e-5), the export falls
back to SMLib's largest everywhere, as before. Import writes each record edge's and vertex's
tolerance.
- `geom::brep::pcurve::EdgeUse` carries its edge record's tolerance, and a pcurve is fitted to
it where it is larger than the face's.
- The kernel's decoded body keeps its record's edge and vertex tolerances
(`Body::tolerances`, in its edge and vertex order) after an SMLib operation and a saved body's
decode, and keeps them through a rigid placement. Its record writes them again; anything that
builds a new solid drops them.
SMLIB_REV moves to the fork commit that adds the arrays (smlib-blends-abi2 4a67471, ABI 2).
Rig and ladder fillet and chamfer cases on SMLib: 43 pass before, 60 now, none lost. Tests: a
pcurve fitted to its use's own tolerance, and the ladder's 08/006 cylinder rim chamfer whose
record, saved body and placed copy all stay valid and SMLib's check takes back.

A pick at the vertex where a cylinder's seam meets its rim lies on both edges. The body's
nearest-edge order took the seam on SMLib-made bodies, and SMLib refused to chamfer it
(the ladder's part chamfer, step 22, SM_ERR_INVALID_INPUT). A seam or a tangent join is never a
blend's edge, so a pick as near to one as to a sharp edge takes the sharp edge; anywhere else the
nearest edge stands.
Test: every pick round a cylinder's top rim, the seam's end among them, takes the rim.

Every blend entry point asks `backend()` and, on SMLib, hands its arguments to blend_smlib.rs:
fillet, fillet_each and fillet_radii (a radius per edge), fillet_g2 (SMLib's G2 blend-curve
section between the round's contacts), fillet_chord (constant-width section), chamfer, and
fillet_variable_spline (the radius law as an SMLib B-spline law; fillet_variable and
fillet_variable_points reach it, and fillet_max, fillet_max_each and fillet_tapered run on these).
Options SMLib has no construction for are refused as "not supported yet", never built by truck:
G2 corner patches, and chamfers with two different setbacks (distance and distance, or distance
and angle; equal setbacks are the equal-distance chamfer).
Each pick takes the body's nearest edge in its own edge order, as truck's blends do, and SMLib is
given that edge's midpoint, so a pick at a vertex never leaves SMLib to choose between edges. The
body goes in tagged as operand 0, SMLib's check must pass, and the decoded result carries SMLib's
history in the body's orders, the blend faces given FaceOrigin::Edge of the edge each replaced
(the picked edges and the rest of their tangent chains). The truck path is unchanged.
Tests (with the feature): a round's volume and its face's origin, a size per edge for rounds and
chamfers, a linear law from either end, refused sizes and picks.

The Rust side of the fork's smlib_blend and smlib_fillet_variable, which the kernel's fillets and
chamfers need on SMLib: `Brep::blend` takes a size per picked edge and a `Blend` (circular round,
curvature-continuous round between the round's contacts, constant-chord round, equal-distance
chamfer); `Brep::fillet_variable` rounds one edge with a clamped B-spline radius law from the end
nearest a start point. Selection errors map as for the other picking operations.
SMLIB_REV moves to the fork commit that adds them (smlib-blends, on capi-solidcraft ffcf56d).

The fork's booleans now hand out closed non-manifold results (SMLIB_REV e87e9b3, ABI 3): solids
touching each other along an edge or at a vertex, which the C API refused as "not a closed
solid". The SMLib → schema 4 mapping now gives each closed boundary its own record shell: the
faces sharing one runtime shell on the empty side and one on the material side, so solids that
share their empty side's runtime shell get a shell each. An edge or vertex faces of more than
one shell use is split into one copy per shell (same curve, interval and point), so every
shell is a closed manifold boundary; regions list each shell as before. The history follows: an
Order's `pieces` give each record edge of a split SMLib edge with the faces it bounds, and each
piece keeps the edge's origins.
SMLib's own check refuses the radial order of faces round an edge solids share, so a
non-manifold result is checked as the separate solids it becomes (imported as given). A solid
touching itself along an edge (one shell using an edge more than twice) is still refused, now
as "not supported yet: a solid touching itself along an edge".
Tests: cubes sharing an edge or a vertex unite into two shells of 1000 mm³ each, every face and
edge's history verified against the geometry; two opposite quarters cut off a slab leave two
solids. Of the pinch tests run through SMLib, cut_leaving_pieces_meeting_along_a_line now
passes; the other nine are solids touching themselves.

The kernel runs exact helical sweeps and never resizes; the check that

On SOLIDCRAFT_KERNEL=smlib the thread's groove (the ISO 68-1 trapezoid, as before) is a B-rep
screw sweep (kernel::sweep_helix, SMLib's screw sweep) cut from the body by the B-rep boolean,
whose history carries the threaded face's names on. Truck keeps the faceted groove and the
faceted boolean. thread_groove_shape holds what both build from; the size checks before it
(a hole or shaft off the thread's size is refused with the size to use) are unchanged, so

revolve and revolve_whole, extrude_tapered(_between), sweep and sweep_with, loft,
loft_with_rails, loft_regions and sweep_helix (coils, and the threads' grooves) build their
bodies with the fork's sweeps (smlib_sweeps.rs): the profile's segments go to SMLib as curves
(lines, arcs, Béziers and conics as NURBS), the result comes back through its schema 4 record,
and one SMLib's own check refuses is an error. What SMLib has no sweep for answers "not
supported yet", never truck's sweep: twists, end scales, guide rails and orientation
directions; paths with corners and paths of points; lofts with holes or to a point; draft
extrusions of profiles with holes or with a straight foot.
History is in the builders' vocabulary, found from the result's geometry as provenance.rs does
for operations without exact history: a wall comes from the segments its start edge runs along
(and, for extrusions and revolutions, whose middles it holds half-way), the face in the start
plane where the profile bounds it is the start cap, the one at the end the end cap. Straight
extrusions also carry their faces' construction sources (ExtrudeCap, ExtrudeSide), which the
box and cylinder certificates need. The loft's section matching is truck's own, now
loft_numbered_loops (split out of loft_numbered_wires, unchanged), so both kernels pair the
same vertices.

The SMLib shell passed the user's pick points to SMLib, which refuses a point as near to two
faces; a pick on a hole's wall at the line between its two halves (kernel-cases shell/4010)
failed. The open faces are now picked as truck's shell picks them (the face of the nearest
triangle), grown by the faces on the same surface joined to them (offset::with_same_surface:
a round wall stored in pieces opens whole), and SMLib gets one point inside each.
Offset faces keeps its design on both kernels: when moving the faces fails on a body with
split lines, the chosen pieces are pressed (swept and joined or cut) instead, as truck's path
always did; the booleans of the press run on the selected kernel.

smlib_body_ordered keeps SMLib's face and edge order for history only where SMLib's export
numbers the body as its record does, and compared each loop edge for edge in the same order
and direction. SMLib walks a face whose surface it turned (a hole's wall, a concave cylinder)
the other way round and may start the loop elsewhere, so a plate with a hole lost its history
through every SMLib boolean and shell although its faces and edges are numbered alike. A loop
now matches when it walks the same edges in the same cyclic order, or in the opposite order
with every edge reversed.

With SOLIDCRAFT_KERNEL=smlib (the one kernel switch), shell, offset_faces and thicken send
the body to SMLib tagged as operand 0 (offset_backend.rs) and bring the result back with
SMLib's own history, as booleans do. A result SMLib's check refuses is an error.
SMLib's tags travel through the copies its offset makes, so a shell's inner wall and a
thickened sheet's moved copy read as pieces (Split) of the face they came from. A result face
lying more than half the operation's distance from its tagged face is recorded as that face's
offset (FaceOrigin::Offset) and its edges as where its faces meet; a thickened sheet's walls,
new to SMLib, are recorded as made in place of the sheet edge their edges are tagged with, as
truck's thicken records them. Offset faces pick the faces truck's path picks (a round wall's
pieces together) and pass SMLib one point inside each; the moved faces are Modified.
The histories are checked against the geometry as truck's are (modify_history_tests), with
the analytic volumes, the thicken direction, and the refusal of walls past the L-shaped body's
inradius (8.79) that its box (half extent 10) let through before.

The analytic mapping refused every revolution that is none of SMLib's plane, cylinder, cone,
sphere or torus (a profile of any other curve, a placement that is no rigid motion), which
now also kept those faces from kernel-smlib's exact rational B-spline import (da7ccba9). Such a
face now stays a revolution, so the import sends it as its B-spline; the analytic surfaces are
still taken wherever they fit.

All operations move to SMLib at once, so the selector is no longer the booleans' own:
`SOLIDCRAFT_KERNEL=smlib|truck` (read once, unset is truck, the same refusals for an unknown
value or SMLib in a build without it) is answered by `solidcraft_kernel::backend()`
(crates/kernel/src/backend.rs), which every operation's dispatch calls. The boolean's SMLib path
moves to smlib_boolean.rs. The regression rig's kernel check (`boolean_kernel`) now answers from
the switch, and the rig and CLI set SOLIDCRAFT_KERNEL.

The record of a truck body is built to the body's working tolerance (1e-6 of its size, at
least 1e-5 mm), and truck's offsets and blends leave some edges a few times farther than that
from a face they bound: no pcurve fits, so the record and every SMLib boolean on the body
failed ("pcurve of loop 0 use 0 ...: the curve at 0 lies 3.2e-5 mm off the surface" in a
shelled revolve of the robustness generator). The record for SMLib now retries at ten and a
hundred times the working tolerance for the body, its edges and vertices before refusing; the
saved native body keeps the working tolerance. Robustness seed 64 (a filleted extrusion
joined to a cylinder), refused this way before, now builds as truck does to 1.6e-6 of its
volume.

An SMLib cylinder, cone, sphere or torus decoded as a truck revolution with its parameters
swapped (angle, profile), which truck's own revolutions never have. The tessellator then put a
cone's apex at the wrong angle: a drill point through SMLib and back meshed 41 % too large and
oracle cases 18, 55 and 56 measured wrong areas and volumes. The profile now runs against the
record's v, unswapped, which keeps the record's natural normal and truck's (profile, angle).

Truck's bodies are trusted into SMLib as given, but some miss SMLib's rules by a little (an
edge's vertex 4.4e-5 mm off it against a tolerance of 3.3e-5 after a truck operation), and
every boolean on them was refused by the check of its result. An operand whose trusted import
fails SMLib's check is imported again through SMLib's healer, and the healed body is used only
where SMLib then finds it valid; its numbering is checked against the record as before, so a
heal that renumbers leaves the result without history rather than with a wrong one.

A revolve's flat ends (a line square to the axis turned about it) were refused, so any

The export takes a closed boundary's faces from the side in the empty region and skipped
every use there that is not `same`, a rule meant only for a sheet (a shell that is its own
mate). It tested the chosen side against the mate instead of the shell against itself, so a
cavity's shell, taken from the void's side, lost its faces whose uses run opposite to their
surfaces: "a face no shell uses" for every cut that leaves a void.

Truck extrudes a circle into rational splines, so every truck cylinder reached SMLib as
splines, and a box cut by one came back with edges 0.78 mm off their faces (SMLib's own check
refused it). A rational spline that is a circular arc swept straight along its axis (one
direction linear, the second row the first moved by one vector square to the arc's circle,
weights alike) now goes as SMLib's cylinder with the face's range on it.
The revolution mapping becomes one module for both (import/analytic.rs): each candidate face's
analytic surface is checked against the record's at 25 points of its domain, each point placed
on the analytic surface by its own (u, v), and turned over where the normals disagree.

Truck's planes run through three points, their axes the face's sides, so the SMLib import sent
every truck planar face as a bilinear NURBS patch: SMLib then intersected splines where it has
planes. A plane on any axes now goes as SMLib's plane on unit axes along U and at right angles
in the plane, its range the record's domain on those axes (a face's range need not be tight;
SMLib rebuilds an analytic face's trims from its edges).
A revolution's analytic frame turns to the face's first angle so u starts at 0: SMLib's check
refuses a cylinder whose range ends past 360°. A failed SMLib check of a boolean's result now
says whether an operand already fails it.

Truck holds every round surface as a placed revolution, and a body SMLib made comes back from
truck that way too, so the SMLib import refused spheres, tori and any second boolean on a
first one's result. The import now turns each revolution of a line along or through the axis,
or of a circle centred on it or in a plane through it, under a rigid placement, into SMLib's
analytic surface: the face's range mapped from the revolution's parameters (angles moved into
the first turn: SMLib's torus breaks on a tube range below zero), checked against the
revolution at 25 points, and the face turned over (loops reversed, shell uses flipped) where
the analytic normal runs the other way. Other revolutions are still refused.
A result body's order is checked by each face's boundary edges as well as its identity:
Body::new rephases revolved faces onto new faces with the same edges.

With the `smlib` feature, SOLIDCRAFT_BOOLEANS=smlib (read once per process, default truck)
sends every kernel::boolean through SMLib: each operand's schema 4 record imported and tagged
as operand 0 or 1, SmBrep's boolean, SMLib's check at every level, the result exported and
decoded (with its geometry check). A result either check refuses is an error. The setting
naming SMLib in a build without it, or anything unknown, fails every boolean instead of
quietly running truck, so a comparison never compares truck with itself.
The history is SMLib's tags renumbered into Body::history's index spaces. The export now
reports where each SMLib face and edge lands in canonical order (its arrays follow
SmBrep::GetFaces/GetEdges, the order the tags use). The result's order is checked against the
decoded solid by face and edge identity, the operands' by re-exporting the imported body and
comparing its numbering with the record's; where either differs the result has no history
rather than a wrong one. The result gets the operands' regularization protection and planar
roles as truck's does.

Only the Delaunay layout checked its triangles against the surface. The
grid divides each parameter direction within the tolerance, but on a
doubly curved surface the two sags add up in a cell's middle, along its
diagonal (SMLib torus 1.16x at 0.01, truck sphere 1.23x at 0.1, truck torus
1.40x at 0.01); the patches round a pocket cut into a sphere at its pole
fan out from the cut with no check at all (4.34x at 0.1, 1.90x at 0.01).
Every curved face's finished triangulation now goes through tess::sag:
each triangle is measured at its centroid and at the middle of each side
inside the face, across the surface (along the normal at the point of the
same parameters, which near a pole need not be the nearest), and the side
that leaves the surface most is split, both triangles on it together, so
the face stays conforming. Boundary sides are never split: they carry the
edges' own nodes, shared with the neighbouring face. At a pole the free
parameter of a midpoint comes from the other corners.

A sphere from SMLib cut through its centre keeps one face bounded by its
rim and by its seam from the pole up to the rim, used both ways. Unwrapped
along the loop, both runs of the seam landed on one parameter line and the
loop came out one period short, so the planner took it for a face winding
round the sphere and cut it along a new line of its own. The two seam runs
stayed inside that strip as a slit of zero width, triangulated on each side
separately: open edges along the seam up to the rim (gaps up to 9.5e-3 mm
at chord 0.1), a zero-angle triangle and a non-manifold edge at the pole.
Such a loop is now unwrapped from the node after the pole round to it and
started at the node before it: the seam's uses lie a period apart on either
side of the face's parameter box, which then meshes like any sphere patch,
both uses on the seam's own nodes. It is kept as it was unless the opened
loop spans at most a period with a positive area and no longer winds.

A PlacedRevolution record goes to SMLib as its exact rational B-spline
surface: each profile control point swept round the axis by a full circle of
four rational quadratic quarters starting at the face's first angle, then
mapped by the placement. The circle's parameter is not the angle, so the
face's angle range is converted pointwise and its pcurves are not carried
(SMLib rebuilds the trims). Where the placement mirrors, the record's natural
normal is the opposite of the map's, so the directions swap.
The B-spline matches the record's surface to 1e-12 with the same normal,
forward or not, mirrored or not; truck's sphere and torus now reach SMLib
with their analytic volume (1e-6) as manifold solids.

display mesh, whose faces share each edge's points.
- It matched vertices by rounding to a 1e-6 mm grid, which splits points a rounding error apart
across a cell boundary. It now joins vertices closer than `tolerance.weld_mm` (default 1e-4 mm).
Both cases now have 0 open edges, also with the weld at 1e-6 mm.

Tiers: primitives; booleans in the degeneracy classes (coincident and coplanar faces, edge-on-edge,
vertex-on-face, tangent along a line and a circle, near-tangent gaps and overlaps of 1e-3 and
1e-6 mm, seam and pole crossings) and cuts that end in a single line (a knife-edge wedge, a V
groove and a cylinder that pinch the part in two, a hole tangent to a face, a notch flush with an
end); line-and-arc extrudes and revolves (partial, touching the axis); spline profiles, sweeps
and lofts; holes and tapped holes (blind, drilled, counterbore, countersink, M5-M8 taps, into a
curved face, near and tangent to an edge, crossing); modelled threads (external, fine, partial,
to a shoulder, internal, into a chamfer, at a filleted shoulder); fillets (constant, tangent
chains, convex and concave, variable down to 1e-3 and to 0 at a vertex, corners with equal and
unequal radii, g2 corners); chamfers (two distances, angle, three- and two-edge corners, curved);
shells and offsets; patterns and mirrors (overlapping instances that cut a core free); and
cumulative parts.
A running part grows one tier at a time through `base` (back wall, revolved boss and slot,
spline window, tapped holes, rounds, chamfers, shell, vents), and the last case adds its thread:
it carries every tier. Answers are analytic wherever the geometry has them (Pappus, Steinmetz,
ISO 68-1 basic thread profiles, exact Gauss quadrature of Bezier profiles, inclusion-exclusion
for chamfered corners), otherwise invariants; each `method` gives the derivation, and
tools/kernel-ladder/cases.py (standard-library Python, like tools/oracle-analytic) writes them.
Capabilities SolidCraft lacks are `missing` cases: multi-start threads, thread runout lengths,
fillet corner setbacks.
The golden is the first recording on truck, each tier sorted by its time. SMLib booleans are
not on this branch yet, so the smlib column records "not supported yet" for every case.

The ladder orders kernel operations by complexity instead of by random goldens: a manifest
(tests/kernel-cases/ladder/ladder.json) lists tiers in order and each tier's cases in order;
every case is graded against its own answer like any rig case, and a golden
(tests/kernel-cases/ladder/golden.json) records per case and kernel the status, the commands'
time and what the kernel made. A run compares with the golden and flags slowdowns (over twice the
time and 0.25 s more), status changes and changed counts. `--record REASON` re-measures one case
at a time, rewrites the golden with its reason and sorts each tier by the first kernel's time.
The report, docs/kernel-ladder.md, gives per tier and kernel the counts per status and the
frontier: the first case in ladder order the kernel fails. It reuses the rig's process-per-case
runner, timeout and cells; results now carry their path under tests/kernel-cases/ so cases from
other areas can be listed in a tier. The README documents `base`, `missing` and the ladder.

What the complexity ladder needs from the rig's case runner, kept in the one runner:
- A script may name a `base` case directory: that case's commands (and its own base's, up to
32 deep) run first, so a ladder case starts from the previous tier's finished part without
copying its commands. `$CASE` is each recipe's own directory; `$OUT` is the running case's
scratch directory, in its bases too.
- `missing` in expected.json reports the case as not supported yet without running it: a
capability with no command or parameter (multi-start threads, fillet setbacks) stays visible
instead of being faked with a stand-in.
- Each result carries `seconds` (the commands' own time, without process start or grading) and
`measured` (body count, face/edge/vertex counts, volume, area), for the ladder's golden.

- When SMLib's record conversion says "not supported yet" (revolved surfaces, traced intersection

body. solidcraft_kernel::SmlibCheck carries the three outcomes.

SMLib bounds an intersection edge on a piece of its spline (seed 32 intersect:
a block and a cylinder, the top disc's edges), and the truck decode refused
such an edge ("not supported yet: a spline or intersection edge on part of its
curve"), since truck bounds an edge by its curve's whole range.
bspline::segment cuts a B-spline to a sub-interval of its domain exactly:
Boehm insertion of both ends until each has multiplicity p, then the knots and
control points between them, clamped on the interval. The same points at the
same parameters, so the edge keeps its interval and the record its numbers.
load_edge_curve loads a spline or rational spline edge on part of its curve as
that piece; an intersection edge on part of its curve is still refused. Our
own records (interval = the curve's range) load as before.
Tests: segments of a rational cubic with a double knot, inside a span, across
knots, from or to a domain end, match the whole curve within 1e-12; both
spline kinds load on a piece with that range and the same points, and beyond
the domain are refused; SMLib's block ∩ cylinder decodes (it was refused) with
π r² h within 1e-3.

The adapter loads an analytic torus as truck's revolution of the whole profile
circle, a rational quadratic closed on itself, so an SMLib torus is one face
bounded by its two seam circles, each used both ways. The display evaluator's
domain gave a revolution a period around its axis only: projected along the
profile the loop jumped from one end of the knot interval to the other at its
start vertex, the plan failed ("boundary crosses itself") and the body fell
back to truck's mesher, which meshes a sphere bounded by its seam alone as
nothing (seed 60 union, a torus beside a sphere: 925.0 of 990.7 mm³).
tess::uv::closed_curve detects a closed profile the way closed does a closed
spline surface (clamped knots, first and last control point and weight the
same within 1e-9 of the polygon's extent; the shared checks are factored out),
the domain then has period = the profile's knot interval along it, and
EvalSurface::wrap/derivs wrap that parameter back into the interval, so the
plan's projection, unwrapping and both evaluators treat it as periodic. A
cylinder's or cone's line profile is unchanged.
Tests: a revolved whole circle, either parameter order, has both periods and
evaluates a period away as inside; SMLib's torus, alone and beside a sphere,
decodes without meshing to orient it, plans every face and measures within
1e-3 of 2π²Rr² (+ 4/3 πr³). With the closed profile undone the torus plan
fails as above.

Results of SMLib booleans on its own spheres came back wrong through
body_from_smlib (side-by-side runner: seed 13 cut −1611.9, seed 61 cut −252.4
against SMLib's 4056.9, seeds 46/61 union 80 % short). The schema 4 records were
right (check_geometry passes, outer loops counter-clockwise, shells out of the
material); three things on the truck side were not:
- Body::new orients a solid by the volume of truck's coarse mesh, and truck's
mesher meshes a sphere bounded by its seam alone as nothing: the rest of the
body set the sign and turned it inside out. A foreign record is oriented by
its shells, so body_from_smlib now builds the body with Body::oriented
(revolved faces turned as before, orientation kept, nothing meshed).
- rephase_revolved turns each revolved face so it sits around angle π. A face
that uses its seam both ways goes all the way round; turning its surface ran
the wrap through the face's hole, the display plan failed and the sphere
meshed as nothing. Such faces now keep their wrap on their seam (truck's own
primitives have none: their round faces are split).
- The display plan opened only a loop of one seam used both ways. A sphere face
whose meridian a trim splits uses each piece both ways, turning back at each
pole, and projected onto one parameter line ("boundary crosses itself"), so
the whole body fell back to truck's mesher and lost its sphere faces. A loop
through both poles that turns straight back at one now has its run between
the poles moved one period along, whichever way keeps it within one period
with a positive area (poles split as the planner splits them); the routing
check finds such loops too.
Test: SMLib's sphere less a box cap beside its seam, across it (seam split) and
a bar bored into its side away from the seam decode without meshing to orient,
oriented as recorded, every face meshed, within 1e-3 of the exact volume.
Before, the decode meshed the body to orient it; with only the plan's pole
handling undone the −x cap measures 50.3 of 469.1 mm³, with only the
rephase undone the bored ball 252.4 of 4059.5.

- solidcraft-cli and solidcraft-engine forward an `smlib` feature to solidcraft-kernel/smlib, so
`cargo build -p solidcraft-cli --features smlib` gives the rig SMLib's check.
- solidcraft_kernel::boolean_kernel() says which kernel this process runs booleans on.
`default` until the SMLib switch (SOLIDCRAFT_BOOLEANS=smlib) lands and answers there. An smlib
run on a build without the switch reports "not supported yet" instead of grading the default
kernel under SMLib's name.

Rows without an analytic volume (the fuzz seeds) get one from the
primitives' definitions, by no kernel: along each vertical line both
operands are exact z intervals, combined exactly, integrated over a grid
whose cell edges include every straight face, with the half-resolution
grid bounding what error is left. Each kernel's volume is graded against
it (within 1e-3 relative or 3x that bound), in the JSON per row and in the
report's summary.
On 64 seeds truck is right on all 192 rows. SMLib's own measure is wrong on
13, all with cylinders or spheres, although truck's measure of the same
exported bodies is right on every one of them; 5 give no closed solid.

Every geometry case the old kernel got wrong becomes tests/kernel-cases/<area>/<id>/: an
engine script or oracle recipe, and expected.json with the right answer, from analysis or a
hand calculation, or else the invariants. Never a kernel's output.
- solidcraft-cli kernel-cases <dir>...: runs a case and grades it. The checks are the outcome
(succeeds, or refuses cleanly), the body count, and one closed shell per body that passes the
record's structure and geometry checks and, with SMLib built, SMLib's check(All). Counts,
volume, area, centroid and box are graded where the case gives them. Each run is pass, fail,
not supported yet or crash.
- cargo xtask kernel-cases [--kernel default|smlib|both]: one process per case, so a native crash
or a hang (--timeout) is that case's result. It writes docs/kernel-cases.md: coverage per area
and source, results per kernel, and the sources looked at and skipped (<area>/skipped.json).
- solidcraft_kernel::validity and smlib_built, which the rig's checks use.
tests/kernel-cases/README.md gives the format.

When SMLib's volume of a boolean result differs from truck's, the report could
not tell a wrong body from a wrong SMLib measure. The runner now measures the
result it exports back to truck as well, keeps that volume in the JSON, and
shows it in the export column wherever it leaves SMLib's own measure or SMLib
could not measure the body at all.

The side-by-side runner now reports how long each boolean takes on truck and
on SMLib (the call alone), and apart from that the SMLib side's conversions:
the operands' truck→SMLib import and the result's SMLib→truck export, which
the app pays while truck still holds the bodies. The report gains a times
summary (median, worst, total), solid counts, the analytic volume of each named
case's union, intersection and cut, and how many results land on it.
It also runs the "each cut gets slower" case from TASK_kernel-smlib-booleans as
a named sequence: a 63.6 × 31.7 × 9.5 block, a Ø20 × 10 boss joined on top, a
slot front to back, a Ø6 cross hole through the boss and a slot that splits
the block, each step on the previous result. SMLib keeps its own results from
step to step (only the tools come from truck), in a child process like the
cases, and every step's volume is checked against its closed form.

Now it runs solidcraft_smlib::Brep::boolean on the tagged operands (cut maps
to Subtract, None is an empty result), reads the result's history from the

report compares truck and SMLib on real results.

truck lists some planar faces' hole loops before the outer loop, so the
rule that loops[0] is the outer loop never held for truck's records; moving
it in the adapter would renumber those faces' edges, which history and
names stand on. The outer loop is the one that runs counter-clockwise about
the natural normal (what check_geometry checks); the order is the
producer's, and SMLib's import puts the outer loop first, as SMLib needs.

check_geometry compared pcurve ends with edge points only, so a loop whose
pcurves enclose nothing passed whenever its uses lift onto the same 3D points:
SMLib's hole-rim fillet with both seam uses on u = 0, or a whole sphere whose
pole-to-pole seam has both uses on one line (the continuity check skips the
pole). Such a face has no surface and meshes to nothing.
Each edge loop's signed (u, v) area is now taken over 16 points of each use's
pcurve: a loop within 1e-9 of the square of its extent of zero is refused
(Problem::Empty), and each face must have exactly one counter-clockwise loop
about the natural normal, the rest clockwise (Problem::Turn). Outer and inner
are told apart by area rather than position, because the truck adapter writes a
face's wires in truck's order, which puts a hole first on some planar faces of
the sample designs (the model cache test caught it).
Fixtures: the pole-to-pole seam on one line, and a sheet whose plane axes are
swapped so its loop runs clockwise; a seamed sphere passes.

A spline surface whose first and last control rows coincide in a direction
(points and weights, knots clamped there) closes on itself, but the display
evaluator's domain gave NURBS no period. The pcurve routine therefore never
moved a seam's second use by a period: SMLib's fillet round a hole's rim (a
rational spline closed in u) got both seam pcurves on u = 0, its outer loop
enclosed no (u, v) area, the decoded face tessellated to nothing and the body
measured 6839.73 mm3 against SMLib's 6989.00.
tess::uv::closed detects the closure from the record, within 1e-9 of the
control net's extent; the domain then has period = the active knot interval's
width, and the evaluator wraps a parameter outside that interval back inside
it, so pcurves, projection, sizing and the display plan all treat the direction
as periodic. The record stays as it is. The display plan hands both evaluators
wrapped parameters (the GPU does not wrap).
Tests: a rational torus band, a NURBS cylinder and a NURBS dome with a pole,
each bounded by a seam used twice, get seam pcurves one period apart; a record
of the band passes check_geometry and its seam uses on one line are refused;
SMLib's hole-rim fillet decodes with every face meshed and SMLib's volume
within 1e-3.

profile stopped at the axis). OFFSET_SURFACE of the analytic kinds reads as the moved
surface, checked at each level. Hyperbola and parabola edges read as exact rational
quadratic pieces and a Bezier on STEP's parameter. Faces winding around a revolution get
seams along its profile. Every mapping is checked point by point and normal by normal
against STEP's own surface.

Schema 4 counts every pcurve's control points as items, which schema 3 had
none of, so a body that fitted the old 1,000,000 no longer does (a STEP
plate of 50k faces). The binary envelope's own caps on bytes, values and
entries per collection still bound a body.

A face winding around a closed (non-periodic) spline surface without a seam edge has loops
that jump across the surface's domain; it is refused for now instead of making a record whose
loops do not close. The step-conformance parts are read in a test, and the kernel's ignored
corpus comparison builds each record back into a truck solid to compare volumes.

A face on a cylinder, cone or sphere bounded by loops that go round the axis (a band
between two circles, a dome on its equator, a cone on its base and apex) gets a seam:
a ruling or meridian from one loop to the other (split where it has no vertex at that
angle) or to the pole it covers, so every loop closes in (u, v) as schema 4 requires.
Pcurves may be fitted up to 1 mm off for edges that lie off their surfaces. The kernel
gets an ignored corpus test comparing truck's face and edge counts with schema 4's.

Boxes and cylinders go into SMLib as truck's own B-reps, through their
schema 4 records (smlib_body), so both kernels start from the same input
whatever the axis. Spheres and tori are SMLib's primitives about +Z, like
truck's, since the import doesn't take truck's revolved surfaces yet. All
41 cases' operands now build; only the boolean itself waits for its shim.

SMLib B-reps leave the C API as its flat arrays, read through the crate's
one flat wrapper (crate::flat::Flat, copied out as import::Arrays), and
become schema 4 records: shell pairs merged, sheets collapsed, radial cycles
normalised, analytic surfaces as their kinds (narrowing cones kept), loops
reversed where SMLib's surface is inside out, every pcurve from
brep::pcurve, canonical order, then validate() and check_geometry(). Edges
arrive as their own kinds; NURBS edges that are lines or circular arcs (the
primitives' circles) are recognised as a fallback and counted. With the
kernel's `smlib` feature, body_from_smlib() decodes them into a Body.
Adds the cylinder, sphere, cone and torus primitives. Each primitive passes
SMLib's own check at every level, its volume from the exact mass properties
matches the closed form, and it goes round SMLib -> schema 4 -> SMLib with
its counts, volume and a clean check. Truck now meshes a whole sphere
bounded only by its seam (SMLib's sphere) through the display plan.
SMLIB_REV moves to the fork's capi-primitives (the primitives on capi-flat
40bb855).

SMLIB_REV moves to the fork's capi-static 40bb855 (flat arrays, C ABI 2).
flat.rs wraps them (Flat: arrays by id, Brep::export, Flat::import,
Brep::is_manifold_solid; FFI in ffi/flat.rs). import.rs lays a schema 4 record
out as those arrays: a closed shell becomes one SMLib shell per region it
separates, a sheet's shell holds both sides of each face, the infinite region
is marked void as SMLib has it, pcurves become UV trims on B-spline faces only
(reversed for edgeuses against their edge), planes with non-unit axes go as
their exact bilinear patch. Brep::from_record builds the SMLib body.
kernel: brep_record(body) gives a body's schema 4 record, and smlib_body
(feature smlib) its SMLib body, trusted (no healer: healing moved a
cylinder's volume by 9e-7). Box, cylinder and tilted cylinder keep their
analytic volume in SMLib (1e-9, 1e-6) and are manifold solids; truck's
spheres and tori are revolutions, refused with "not supported yet" for now.

A whole sphere bounded only by its seam (SMLib's sphere: one meridian
used twice) came out with both uses on the same u line, a loop that
encloses nothing. Two causes in the per-loop closure:
- The pole-junction search took any positive signed area as the right
turn. With the two uses on one line the area is rounding, and in most
frames that rounding is a tiny positive number, so "no shift" won over
the period shift. A turn now needs more than 1e-9 of the loop's
period box.
- Junctions counted as poles only where the surface collapses exactly.
Ends within the tolerance of a pole (as a kernel's records have them)
were closed to the nearest period instead. A junction is now free
where moving its periodic parameter by half a period stays within the
tolerance, and fit samples within a quarter of it take their free
parameter from a neighbour, so the pcurve runs straight into the pole.
Tests: the sphere bounded by its seam in four frames, three meridian
angles, circle and NURBS meridians, both loop orders, ends at or a tenth
of the tolerance off the poles; and a torus bounded by its two seams.

ValidatePointers, then AssertValid over the whole topology graph (the fork's

AssertValid hit on every periodic face.

decode builds topology with Edge::new_unchecked and Face::new_unchecked,
so a record whose curves miss their vertices or whose pcurves miss their
edges loaded and failed later inside truck. It now runs check_geometry
after validate and refuses such a record (a cache miss at the IO
boundary). Only our own cache feeds it today; STEP and SMLib exports will.

validate() is structural only, and a kernel adapter that builds topology
from the records without its own checks (truck's new_unchecked) would take
an edge whose curve misses its vertices and fail later inside the kernel.
check_geometry spot-checks what it assumes, each against the record's own
tolerance: every edge's curve meets its vertices at its interval's ends;
every oriented edge's pcurve, lifted through its face's surface, lies on
the edge's curve at the interval's ends and middle and continues the use
before it on the same period; every vertex loop's vertex lies on its
surface. A fixed number of evaluations per record, so linear in the item
budget; a point that cannot be evaluated is an error (Mismatch, naming the
record), never a panic.
The schema fixtures now carry real planes and pcurves (from
pcurve::pcurves), so every form passes; one-defect fixtures and hostile
records cover the refusals.

examples/smlib_booleans runs truck and SMLib on the same cases (named pairs
whose results are known by hand, then fuzz::boolean_shapes for N seeds),
each as union, intersection and cut, and compares volume, face and edge
counts and the shape of the history (how many faces Kept, Modified, Split,
Merged, Generated; edges from an operand edge, new, or without origin). It
writes a JSON and a Markdown report and never changes the default kernel.
SMLib runs in a child process per case, so a crash inside it is reported as
that case's result. Its primitives and booleans arrive with the operation
shims; until a call exists the case is reported as not run on SMLib.

Brep::tagged gives a copy whose faces and edges are tagged as one operand's;
after an operation on tagged copies, Brep::history reads back each result
face's origins and change (Kept, Modified, Split, Merged, Generated) and each
edge's faces and origin edges, as SMLib itself carried them through the
operation's splits, merges, copies and coincidences. Raw::history turns that
into solidcraft_geom's History, renumbered into canonical order by each
body's Order, with a new edge recorded as where its two faces meet.
The FFI declarations are in src/ffi/history.rs, beside ffi.rs. Tests cover
the C layout, hostile records, the meeting edges, renumbering and bad
orders, and (with SMLib built) a tagged box.

A new crate, solidcraft-step (L1, no modelling backend), holds the Part 21
parser (moved from the kernel, which now reads through it) and STEP geometry
as plain data: lines, conics, B-splines (rational and implied knots),
polylines, trimmed curves, surface curves with their pcurves, 3D offset
curves; planes, cylinders, cones, spheres, tori (degenerate too), B-spline
surfaces, revolutions, linear extrusions, offset and rectangular trimmed
surfaces. Each keeps STEP's own definition and parameterisation, in mm and
radians, with pcurves scaled by their surface's parameter units. Shared
entities stay shared. A writer emits the same entities back, deduplicated.
Tests per entity check values against analytic points, units, round trips
and hostile input; an ignored test reads and round-trips every edge curve
and face surface of the tangency-labs/models STEP files.

A new crate (L1, only the kernel uses it) builds tangency-labs/smlib's SMLib,
SM_API and C API with the cc crate when its `native` feature is on, from the
commit in crates/smlib/SMLIB_REV (scripts/fetch-smlib.sh fetches just those
sources). The kernel's `smlib` feature turns it on. Without it nothing C++
is built and every call returns NotBuilt, so workspace builds need no C++
toolchain.
unsafe is confined to src/ffi.rs. The wrapper owns handles, maps statuses to
errors, checks the C API version, and sends SMLib's per-call log to the log
crate. Crash reports note the native kernel call in flight.

SMLib makes narrowing cones with a negative half angle; schema 4 now takes

The adapter now saves each edge's curve record and interval when the edge first appears and
computes every face's pcurves from those records and the surface record it writes, with the
shared plain-record routine; the truck-face version in native/pcurve.rs is deleted. Loops go
in as the record keeps them (relative to the surface), so a reversed face no longer has its
wires reversed and back again.
The native tests are ported (adapter::face_alone gives one face's record for them). The cut
body's intersection pcurves now fit at 1e-6 mm too: the routine follows the converged
intersection, and truck's own points are within its 1e-6 mm of it, which the lift check
allows for on intersection edges. docs/native-brep.md says where pcurves come from and what
a surface intersection's point at t is.

solidcraft_geom::brep::pcurve::pcurves(surface, loops, tolerance) computes every edge use's
pcurve from our own records: the surface record and, per loop, each use's curve record,
interval and direction. No backend's parameter space is involved, so the truck adapter and an
SMLib conversion can share it (owner decision 2026-10-21).
brep::eval evaluates every schema 4 kind: planes, splines and revolutions through the display
evaluator (EvalSurface, EvalCurve, tess::uv), cylinders, cones, spheres and tori in closed
form in angle and height, and a surface intersection as the point of both surfaces in the
leader's normal plane (what truck's subs converges to), by Newton's method.
Exact in our parameters: lines, polylines and whole splines on planes; a circle about the axis
of a cylinder, cone, sphere or torus (a u-line); a line along a cylinder's or cone's ruling (a
v-line). Each exact pcurve is checked by lifting it; everything else is the cubic B-spline fit
the kernel had, with its span and round caps. Curve2::eval moves here from the kernel.

The parameter box, the projection of a point onto an evaluator surface (closed form on a
plane, damped Gauss-Newton elsewhere), unwrapping and the pole test work on geom's
EvalSurface alone. They move from the kernel's tessellator to solidcraft_geom::tess::uv so a
pcurve routine on plain B-rep records can use them without truck; the kernel re-exports them

A test over every design the repository keeps (the action matrix's
corpus: old design files, examples, regressions, demo and typical
designs, the oracle recipes; plus the sample designs, the engine's
design fixtures and the older designs of the hole matrix, taper and
projection tests: 154 designs). Each is rebuilt and recorded in
tests/naming/<group>/<design>.txt: per body the names of its faces and
edges with whether each follows exact history, and every stored name
(feature face picks, fillet/chamfer/bend edges, sheet metal edges, the
face a sketch is attached to) with the face or edge it finds now. A
difference fails with the design and the changed lines; record an
intended change with NAMING_CORPUS_BLESS=1, as FEATURE_WALK_BLESS does.
Face and edge indices are left out on purpose. They are the kernel's
order: truck already gives a fillet's or a boolean's faces in another
order from one process to the next (oracle 07 and 37 changed on every
run), and SMLib will order them differently again, while what must not
change is the names and what references find. Names are listed sorted.
One design's names themselves change between runs on truck
(closed_sweep_torus_cut: level wall halves numbered #1/#2 in kernel
face order); it is listed in UNSTABLE with the reason and its
difference printed instead of failed on.
Records made on this branch (truck), macOS. The whole corpus builds in

the canonical order (a reversed face walked backwards), each curve and
surface kind's parameterisation, pcurve rules, validation, history, the
SCBREP05 envelope and what the truck adapter writes and refuses.
A test lifts every pcurve of a box, a filleted box with a bore and a
sphere onto its face and checks it is its own edge at both ends and the
middle; with a reversed face's pcurves left in truck's oriented order it

Edges, vertices and the body carry the face tolerance (10^-6 of the
body's size, at least 10^-5 mm): truck's traced intersection edges sit
about 1e-6 mm off their surfaces, so the linear tolerance is too tight for
a pcurve to lift onto them. The box-and-fillet golden fixture is the
schema 4 envelope now (NATIVE_BREP_BLESS=1 rewrites it), and the adapter
tests cover a pair of lumps. The model cache's producer revision becomes
solidcraft-truck-adapter/4.

The plain B-rep follows SMLib's flat form with STEP's names: regions
(infinite first), face/wire/vertex shells, oriented faces, faces with a
domain and edge or vertex loops, oriented edges with a pcurve each, edges
with an interval, a tolerance and their list of uses, vertices with a
tolerance. Curves and surfaces are unbounded; their bounds are the edge
interval and the face domain. Loops are relative to the surface's natural
normal. Schema 3's read-only intersection and revolution records go.
The validator keeps schema 3's caps and adds the structural rules:
references, loop shape and connectivity, regions and closed shells, the
pcurve interval, natural parameter ranges, every edge's uses (primary
first, upper = !forward) and the canonical order of shells, faces, edges
and vertices. A reversed face is walked backwards, as truck's edge_iter
walks it, so truck's face and edge indices are the canonical ones.
The truck adapter writes truck's absolute wires as the loops, numbers
everything as the kernel does, and builds regions from the shells (a
tessellated nesting test only when there are several closed shells).
Pcurves come from pcurve::pcurves only; until it supports a face, encode
fails and the body is a cache miss. The envelope signature becomes
SCBREP05.

FaceOrigin, Change, FaceProv, Side, EdgeOrigin, EdgeProv and History move

Each sample of an intersection curve is one of truck's double projections

sample and halfway between. Starting from four samples a span instead of
eight halves that; the checks stay at eight points a span, and the knots
at the curve's own breaks already carry the shape. The cylinder cut by a
tilted box now takes 70 ms at 1e-3 mm and 149 ms at 1e-5 mm for all its

Faces with seams as imported faces have them (the kernel's own
revolutions come in pieces): a cylinder whose seam line is used twice
between two full circles, each a closed edge on one vertex, and a sphere
bounded by one meridian used twice from pole to pole. Their seam uses come
out a period apart, in the base period. The checks now also require every
face's outer loop to turn counter-clockwise in (u, v) for a face along its
surface's normal and clockwise against it, holes the other way: the rule
the pole junctions rely on, which every test body follows.
With SOLIDCRAFT_PCURVE_SVG=<dir>, a test writes each test body's face
loops in (u, v) as SVG for review.

Every edge not exact on a plane gets a cubic 2D B-spline on its curve's own
parameter: through the parameters of the curve's ends, least squares
through samples between (banded normal equations), with spans halved and
sampled twice as densely wherever the lift misses the curve by more than
half the tolerance, at the samples or halfway between them. Knots start
where the curve's parameterisation is less smooth: a spline's own knots
and the vertices of an intersection curve's leader polyline, with the
multiplicity a cubic needs there (without them the cylinder-minus-box
intersection curves took 400 spans at 1e-3 mm). Spans and rounds are
capped; a fit that does not converge, or a curve farther from the surface
than the tolerance allows, fails naming the wire, edge and distance.
Samples are projected with the kernel's own surface parameter search (the
evaluator's form, parameterised as truck parameterises it; truck's search
for surfaces it does not take), each from the one before, unwrapped along
periodic directions. Where the surface collapses (a pole) the undefined
parameter comes from the nearest sample that defines it, so a pcurve runs
straight into the pole. Each wire's uses are then moved by whole periods so
each starts where the one before it ends, starting after a pole junction
if there is one; at further pole junctions the offset that gives the loop
a boundary's turn is taken. The wire then moves into the base period. A
seam edge used twice is fitted once.
Truck places intersection curves on their surfaces to about 1e-6 mm, so
their pcurves need a tolerance of 1e-5 mm or more; the test records that.

A plane's parameters are affine in space, so the pcurve of a line or a
(rational) B-spline on a plane is the curve's own knots and weights with
its control points mapped into (u, v): no fit. Curved surfaces and
intersection curves still return "not supported yet". A test helper checks
every pcurve the way the schema validator does, its interval against the
curve's range, the lift error and the wire's closure in (u, v); the box's
line pcurves lift onto their lines' ends bit for bit.

* Hebrew: translate the new Describe Command label; list he in the control protocol
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Hebrew: catch up with main's catalog and the new ribbon (#3457)
- Translate the 258 messages main added since the branch was cut, drop
the 38 it removed (10 renamed ones keep their translation) and
retranslate the two whose English changed (toolbar → application bar).
- The timeline title is ציר הזמן, matching the glossary.
- Ribbon buttons split their labels into two lines from the start of
the string; Hebrew labels come in display order, so the first line
showed the end of the phrase ("חדשה / סקיצה"). For right-to-left
labels the first line now takes the words at the end of the string,
and a shortened line loses characters, and shows its ellipsis, on the
left. The word-boundary sweep checks Hebrew from the lines the galley
is built from, since epaint's right-to-left rows carry zero-width
glyphs.

* Hebrew: after rebasing onto main, load the Hebrew face with the cached system fonts
main now searches the system fallback faces once (SystemFonts, on a thread);
the Hebrew face joins that search with its coverage check. Drop the three
camera-animation messages main removed (#4296) from the Hebrew catalog.

* Hebrew: translate the messages main added after the catch-up (#3457)
Translates the messages main added since the last catch-up: the history
bar's buttons and name toggles, the 3D mouse driver and axis mapping, the
thread size columns, the File view (home page), the redesigned Preferences, the new issue report
dialog, free orbit and the assistant's setup card. Drops the one message
main removed. The catalog has every English message again, so the
complete-catalog checks pass for he.
* Arabic interface language (right-to-left, on the Hebrew bidi path)
Adds an original Arabic translation of the whole English catalog
(assets/locales/ar.json, every message) and registers it. `ar` joins the
complete catalogs, so a message added to en.json later fails the build
until it is translated. It goes through the right-to-left path of #3458
unchanged: crate::bidi puts each message in display order and leaves
every Arabic word's letters in reading order for harfrust, which joins
them with the font's own tables. Ribbon labels use the right-to-left line
split from the same stack.
fonts.rs adds a system Arabic fallback after the Latin interface font,
which keeps spaces, digits and Latin text so each Arabic word stays one
shaped run: Segoe UI/Tahoma/Arial on Windows, SF Arabic/Geeza Pro/
Damascus/Tahoma on macOS, Noto Sans or Naskh Arabic/KACST One/DejaVu Sans
on Linux, or NotoSansArabic-Regular.ttf in CRAFT_FONTS_DIR. It is the first
fallback for an Arabic UI (Arial Unicode, a CJK candidate, has Arabic
letters without joining data) and the last otherwise; like Thai and
Hebrew it is never promoted for a CJK interface.
Tests: the catalog comes back in display order with no directional
controls, and Arabic laid out with a real font lands on screen word by word
in reading order.
* Hebrew: review the catch-up translations; restore the camera-animation messages (#3457)
- Review of the 533 messages translated in the previous commit: 21
corrected. Keys in the motion dialog are keyframes (נקודות מפתח, as
in Add Key), the Design workspace is תכן as in its label, a dropped
"(Direct Driver)" is restored, terms aligned with the rest of the
catalog (פורמט, סוכן קוד, רצועת הכלים), and a few calques reworded.
- Translate ui.animate_view_changes, ui.animation_speed and
ui.look_at_anim_desc, which main has again, so he stays complete.

* Arabic and Hebrew: translate the messages main added since (#3457, #3762)
Both catalogs again carry every English message. The 760 messages main added
since the last rebase (render workspace, material editor, standard views,
sheet metal Path Flange, AI app connections, document-on-disk notices and
more) come from A-AL-ANAZI's translations on #3768; the five Perforate dialog
messages are new here. The earlier Hebrew review is kept on top of them, and
33 of the new Hebrew messages are corrected: "completed" was "perfect"
(מושלם → גמור), Regrade read as ranking (now תיקון צבע מחדש), shaders,
guarantee, the Mirror reflection mode, simulations and displacement.

Each command that names a body (appearance, material, move, ...) mapped it to
its component's own name by working out every placed body's world name and
frame, so a command on a large assembly cost a walk of the whole design. The
list is now kept with the world-placement cache while it is current.
Co-authored-by: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Naming a placed body scanned every occurrence and body of the design, so the
world state and every caller naming all placed bodies grew with bodies times
design size. WorldNames indexes the design once and names each body in time
proportional to its occurrence path; one naming routine serves both it and the
single-body scan. Names are unchanged (a test compares them with the scanning
implementation).

* Viewport: palette-indexed scene and incremental appearance updates
- Move triangle, line and instance colours and opacity into a per-scene
palette (an R32Uint texture, WebGL2-safe); appearance edits update
palette entries instead of vertex bytes.
- Build CPU body triangles as one canonical vertex stream per block with
opaque/glass/faded index lists; an opacity class change rewrites only
the index list.
- Cache resolved body appearances by a per-body key, so an edit resolves
only the bodies whose look changed.
- Split the model scene key from the session revision: selection and
view-only commands no longer rebuild or upload the model scene.
- Replace the O(n^2) section-index lookup and per-placement instance scan
with hash lookups.
Co-Authored-By: Claude Code <noreply@anthropic.com>
* Viewport: skip unchanged palette work when rebuilding
- Reuse each body's appearance key while the document is unchanged.

* Viewport: draw block classes as vertex runs, not index lists
A body's vertices are three per triangle in mesh order, so each draw class
is a few runs of the block's vertex buffer: all-opaque blocks need no index
buffer, and an opacity class change uploads nothing. A fragmented class
(more than 64 runs) falls back to one index buffer.
Each triangle is written as one record into a block reserved up front,
which takes the cold scene build of a 7.1M-triangle assembly from 97 ms
to 55 ms (main: 83 ms).
Also fix reindexing a block whose bodies are drawn elsewhere: it walked
the mesh's triangles from that body's start, past its own vertices.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* Viewport: draw the highlight's own block, and light faded bodies without copies
The highlight scene keeps its feedback (a hovered face, a body copied on
the CPU) in a block of its own; since blocks became vertex runs, only the
model's blocks were drawn, so that feedback was uploaded and never shown.
Draw the highlight's blocks with its triangles.
Whole faded and see-through bodies (another component active, or an
appearance below full opacity) were lit by copying every triangle on the
CPU at each hover change: 85 ms for a design row of 812 bodies. They are
now drawn again from the model's own block vertices, in the highlight
palette with their slots set to the highlight colour, or as placements of
the model's shared triangles. The picture is the same as the copy's.
Adds a GPU frame benchmark for document-tree hover (ignored test).
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* Viewport: count scene uploads, and keep the sorted glass stream across colour edits
Renderer::uploads reports the bytes the model scene's last change uploaded
(geometry, placements, palette rows, planned colours, re-evaluated vertices).
Without order-independent transparency the global glass stream is kept while
the blocks' see-through triangles are the same, so a colour edit on a glass
body uploads palette rows only. Tests assert both on a GPU.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* Viewport: keep palette slots and looks without rehashing every body
A rebuild found every body's palette slots by name and wrote them back,
allocating and hashing a new key per body, and copied every shown name into a
set to check the arena still belongs to the design. Slots are written back only
when a body's faces grew, and the looks cache is pruned only when it holds more
bodies than are shown. Adds the STEP-file benchmark (SOLIDCRAFT_SCALE_STEP) and
the colour command's own time to the assembly benchmark.

* Viewport: round-pick construction lines through the scene palette
The axis and centre feedback for round picks (#4610) drew with a raw colour;

* Viewport: draw faded and see-through bodies from their plans with OIT
A body faded outside the active component, or see-through, left the GPU
tessellation path and was built triangle by triangle on the CPU, so working in
a component of a large assembly rebuilt every other body. Where the renderer
blends see-through surfaces order-independently (GpuTarget::oit, set by the
renderer), a body whose faces share one class is drawn from its plan: chunks
are split by class, opaque passes, AO and the section draw only opaque chunks,
and the OIT pass draws the rest. The sorted fallback keeps them on the CPU.
The model and its highlights decide through one rule (model_plan_class).

A cut (or intersect) that names no bodies went through every body it met,
hidden ones too: a body hidden to keep it out of the cut was cut anyway. When
some of the active component's bodies are hidden, the cut now stores the shown
ones as its targets, so the hidden bodies stay as they are, and stay so once
shown again (the model never depends on what is shown). With nothing hidden it
goes through every body it meets, as before.

Until a connection had shown the token, its first line (up to 16 MiB)
was parsed whole into a JSON value. A line of [0,0,...] that size is
hundreds of MB once parsed, so 16 connections without a token could
make the app run out of memory and lose unsaved work. The token is now
read from the request object without building the rest of it: other
fields are only skipped, and anything but an object with a string

and Douglas-Peucker, and adds lines and cubic Bezier splines through Insert
SVG's add_geometry to a new sketch on the canvas plane, with the canvas'
width, centre, rotation and flip. Holes stay holes; one undo step.
The image's declared width x height is checked before decoding (at most
40 megapixels) and the decoder runs under image::Limits, since canvases
are capped by file size, not pixel count.

* Add Open in Slicer for the selected bodies (#2595)
One command saves the selected bodies as a 3MF in millimetres (an STL if the 3MF can not be written) and opens it in the last slicer used. It is on the File menu, the Mesh tab and the body right-click menu. The first time, or when that slicer is gone, it asks which one with the same list Save as mesh uses. The Save as mesh dialog is unchanged.
* Send slicer files to a private per-user folder (#2595)
Files sent to a slicer used to go to a shared folder in the temp directory. They now go to the user cache folder (mode 0700 on Unix), under a name that stays the same for the same design and bodies, so sending again replaces the file and the slicer can reload it. The file is written to a temporary name and renamed into place. If the name can not be replaced, as on Windows while the slicer holds the file open, the copy gets a number and the status line says so. Files older than seven days are deleted at startup. The first send tells the user that sending again replaces the open file, and so does the tooltip of Open in Slicer. Send to slicer in Save as mesh uses the same path.
* Open files in a running slicer (#2595)
PrusaSlicer, SuperSlicer, Bambu Studio and Cura are started with --single-instance, so a slicer that is already open loads the file instead of opening a second window. OrcaSlicer has no such flag and is left alone, and macOS bundles are single-instance already. PrusaSlicer 3.0 ships a launcher entry that already carries --single-instance-on-url; it keeps that one and never gets a second flag. It is a preference, on by default, and scripts can pass single_instance. Preferences also gets a button to forget the slicer Open in Slicer remembers.
* List slicers the desktop entries say open 3MF or STL (#2595)
On Linux the scan of desktop entries now also lists a program that claims 3MF or STL in MimeType, even when it is not in our table of known slicers. The table still supplies names, ids, icons and flags for the ones it knows. Entries marked NoDisplay or Hidden are skipped, and so are terminal programs and SolidCraft itself. The existing size and count limits stay. The Windows scan now looks inside a Prusa3D folder, where PrusaSlicer installs itself.
* Only start slicers the user can see or chose (#2595)
file.save_mesh took a slicer parameter that could be any executable path, so a script or an MCP client could run any program. The slicer now has to be one of the detected slicers (by id or name) or a program the user already added under Custom, which the app hands to the engine from its settings. The same rule holds for file.open_in_slicer. The agent chat already asked before any file command; its question now also names the slicer.
* Review fixes for Open in Slicer (#2595)
The file name hash keeps all 64 bits instead of 32. When Open in Slicer has to fall back to an STL, the status line now says so. The engine test that sets the chosen programs clears them again. The unused "could not make the folder" message is gone from the catalogs, and the docs say plainly that finding slicers by file type is Linux only.
* Keep unsaved designs apart and hide Open in Slicer in the browser (#2595)
Two unsaved designs with the same name and body names got the same file in the slicer folder. Every document now has a uid that is new for each New, Open and Recover and stays the same for the life of the document, and the file name uses it (with the process id) until the design has a path. At the first Save As the name changes to the path-based one, so the slicer gets one new file; the old one goes with the seven-day sweep.
The browser can not start a program, so Open in Slicer is now disabled there: the engine command reports why, the File menu item and the body and component right-click items are greyed, and starting it anyway says so on the status line instead of opening a dialog. The Save as mesh dialog keeps its browser guard for the open flow too.
* Put the Session doc comment back on Session (#2595)
The new NEXT_UID static had landed between the doc comment and the struct it describes.
* List every install of a slicer, and test the first Save As (#2595)
Detection kept one entry per known slicer, so a system PrusaSlicer 2.9 and a Flatpak 3.0 beta showed up as one. Every distinct install is listed now. The same program found twice, through a desktop entry and through PATH, is still one. When a slicer has several installs, each gets an id made from where it was found (prusa#comprusa3dprusaslicer) that stays the same on every run, and a name worked out from its command and location without running anything: PrusaSlicer (system), PrusaSlicer (Flatpak, beta), PrusaSlicer (AppImage). A lone install keeps its plain id and name. The plain id or name still picks the first install, so a remembered "prusa" keeps working. Single-instance flags and the other per-slicer behaviour go by the id without the install part.
Also a test that the first Save As changes the file name once and later sends keep the name that comes from the saved path.
* Start PrusaSlicer 3.0 first and send the file once it is ready (#2595)
PrusaSlicer 3.0 starts through slic3r-app-launcher, which ignores a file given at a cold start whatever the flag, and loads it over D-Bus when an instance is already running. A small table in slicers.rs names such slicers by their command; today it holds that launcher, so PrusaSlicer 2.9 and OrcaSlicer are untouched. Ready means a name starting with com.prusa3d.prusaslicer.BroadcastListener. is on the session bus, read from busctl --user list with no new dependency. If busctl is missing or fails, nobody waits and the file is sent as before.
When the slicer is not ready, Open in Slicer starts it without the file and looks every 200 ms for up to 10 seconds. The wait runs on another thread, so the window stays live, and the status line says Starting PrusaSlicer. Once the name appears the file is sent with the same arguments as before. If the limit passes, the status line says the slicer did not respond, that the file is already saved, and to send again. A second click during the wait only repeats the Starting line, so there is one launch and one send. Scripts calling file.open_in_slicer wait inside the command by default, or pass wait: return or no.
* Always show the slicer picker for Open in Slicer (#2595)
File > Open in Slicer, the Mesh tab entry and the right-click entry now always open the picker, with the slicer used last time pre-selected, so the usual case is one click or Enter. Scripts and file.open_in_slicer with a slicer still send without a dialog. The preference button that forgot the remembered slicer is gone: it could no longer make anything ask again, and it did not clear the pre-selection either. The guide says how it works now.
* Leave Bambu Studio out of the single-instance list (#2595)
Open files in a running slicer now adds --single-instance for PrusaSlicer, SuperSlicer and Cura only. Bambu Studio is started as it is, so it may open a second window. A test pins that, for the detected slicer and for one the user picked as a custom program. The guide and the preference tooltip no longer name Bambu Studio as getting the flag.
* Sort the English catalog and leave features.md to the generator (#2595)
cargo xtask lists wanted one message moved in en.json after the rebase. docs/features.md is written by the Generated files workflow on main, so the row I had added by hand is gone from this branch; the workflow adds Open in Slicer when it lands.
* Drop the unused folder message from the Vietnamese catalog (#2595)
Vietnamese arrived on main after I removed ui.save_mesh_temp_failed from the other catalogs, so the check that every translated id exists in English failed on it. Nothing uses the message any more.
* Say so when a started slicer can not be found again (#2595)
After Open in Slicer had started a slicer on its own, a failure to look it up again to send the file just returned, so the status line stayed on Starting and then nothing. It now says the slicer was started, that it can not be found to send the file, and where the file is saved. A test covers it.
* Say why a failed busctl ends the wait (#2595)
If busctl fails partway through a wait, the wait stops and the file is sent, the same as when busctl can not be run at all. That is on purpose: a file sent too early is dropped quietly and costs one more send. A comment in wait_for_ready says so.
* Keep the readiness wait inside its limit (#2595)
wait_until asked the probe before checking the deadline, including right after a sleep, so a yes could be accepted after the limit, and busctl ran with no timeout, so one look could outlast the whole wait. The deadline is checked first now, the probe is told how much time is left, and busctl is given at most two seconds (less near the end of a wait) and is killed after that. A hung busctl counts as not telling, which sends the file as before. This covers the first look on the UI thread too. Tests cover a slow probe, the shrinking time left, and a fake busctl that hangs, answers and fails.
* Send the file that was already written once the slicer is ready (#2595)
When the wait for a started slicer ended, the UI ran file.open_in_slicer a second time. That exported the design again on the UI thread, from whatever the session looked like by then, and could write a numbered copy while the timeout message still named the first file. The wait now keeps the slicer it found and the answer of the first call, and opens the file that was written. A test changes the design during the wait and shows the same file is sent, is not written again, no command runs, and no second file appears.
* Send with the single-instance flag after starting a slicer (#2595)
After Open in Slicer has started a launcher that needs a start first, the file has to reach the instance that is now running, so the send that follows a start carries --single-instance whatever the preference says. A normal send, to a slicer that was already up, still follows the preference. A comment in both places says why. The test uses a plain launcher command with the preference off: the normal send has no flag and the send after a start has it.
* Find the remembered slicer again after an uninstall (#2595)
With two installs the remembered key is prusa#prusaslicer. Remove the other install and the lone one is plain prusa, which matched neither the exact key nor the plain-key fallback, so the picker fell back to the first slicer in the list, maybe a different one. The key is now also matched by the part before the #, so the same slicer is pre-selected. A test covers the lone install, a plain key with two installs, an exact key, and that another slicer is never picked.
* Say a second click did not send anything while a slicer starts (#2595)
While a started slicer is being waited for, another click showed Starting <the first slicer> even when it had picked another slicer or other bodies. It now says it is still waiting for that slicer and that nothing else was sent. The test checks the wording and that it names the slicer being waited for.
* Label macOS installs by their application (#2595)
An open -a command resolved its program to /usr/bin/open, so every application on a Mac was labelled system. Labels for open commands now come from the .app path: /Applications is system and a folder under home is shown as ~/Applications. A test with two PrusaSlicer.app bundles and a made-up home checks both labels and that the ids differ.
* Pick the same place for a program found twice every time (#2595)
When two desktop files, or a desktop file and PATH, pointed at one program, the first one read was kept and its file name went into the id, so the ids could change with the order the folders were read in even though nothing was installed or removed. The place that sorts first now speaks for the program. A test with two aliases and a second install lists them with the folders in both orders and gets the same ids and commands.
* Treat flatpak run spelled two ways as one install (#2595)
flatpak run ... and /path/to/flatpak run ... with the same arguments had different install keys, so one invocation could be listed twice. The launcher is now compared by its file name and the arguments are kept, so both give the same key, while a different branch is still its own install. The test uses a real launcher file so the full-path entry is not skipped as stale.
* Say plainly that a late yes is accepted on purpose (#2595)
The comment on wait_until said a slow probe could not accept a yes that came too late. That was not what the code does: no probe is started after the limit, but one already running may finish and its yes is taken, because the file should still go. The comment now says so, with the bound: the limit plus that last probe, which in production is given the time left and so ends by the limit. A test has a probe that runs past the limit and says yes, and checks it is accepted and the wait stays within limit plus the probe time, and that a probe that says no is not followed by another.
* Give reading busctl the same deadline as running it (#2595)
After busctl exited, the output was read with a join that could wait forever if a process it left behind kept the pipe open. The reader now hands the text back over a channel and the wait uses the time that is left of the same limit, and gives up with nothing otherwise. The polling sleep no longer overshoots the time left either. A test uses a fake busctl that backgrounds a sleep with its output inherited and exits at once: the call returns within its limit.
* Tell two different flatpak launchers apart (#2595)
Comparing only the file name of the launcher made /opt/tool-a/flatpak run ... and /usr/bin/flatpak run ... with the same arguments one install even when they are different programs. The launcher is now found the way any program is, through PATH and with links followed, and its name stands in only where it can not be found. The test has flatpak on PATH and the same file by its path as one install, a different executable of the same name as a second, a different branch as a third, and the fallback when there is no PATH.
* Keep waiting when busctl is slow, send only when it is missing or fails (#2595)
Since the busctl timeout, a slow busctl came back as "can not tell", and that was read as send now. One slow look, likely just when a cold PrusaSlicer 3.0 is starting under load, ended the wait and sent the file early, which gets dropped. The look now says why it has nothing: slow means not up yet, so the wait goes on to its limit and then reports that the slicer did not respond; a missing or failing busctl still means it can not be told and the file is sent. The comments name only those two cases. Tests use fake busctl programs: one that hangs keeps the wait going to the limit and times out, a missing one sends at once, one that says not up and then fails sends, and one that names the slicer is ready.
* Do not open an empty path when the answer had no file (#2595)
If the answer kept for a started slicer had no path, the send ran open with an empty string. The tick now says there is no file to send and starts nothing. The test gives a wait with no path, checks the error line, and that the fake slicer was never run.
* Drop the unused folder message from the Danish catalog (#2595)
Danish arrived on main with ui.save_mesh_temp_failed, which this branch removed from English because nothing uses it any more, so the check that every translated id exists in English failed. The entry is gone from the Danish catalog too.
* Always start the 3.0 launcher with the single-instance flag (#2595)
A hand run showed that starting the PrusaSlicer 3.0 launcher with no file while a 3.0 is already running forwards to it and exits when the flag is there, but opens a second full window when it is not. A slow first look at the bus can start the launcher twice, and with the preference off the flag was stripped. A slicer that has to be started first now keeps the flag on that start whatever the preference says, the same reasoning as the send after a start; when nothing runs the flag does no harm. A normal send with the preference off still has none. The test covers the launcher entry, a bare launcher command, a normal send and a slicer that is not on the table.
* Swap --single-instance-on-url where it does not hand the file over (#2595)
A hand run on the PrusaSlicer 2.9.6 Flatpak showed that its entry's --single-instance-on-url does not forward a file to the running instance: every send opened a new one, three after a cold start and two sends. With plain --single-instance the second process finds the first, forwards, and exits. So when a command carries --single-instance-on-url and the slicer is not on the wait table, that is, not the 3.0 launcher, it is replaced by --single-instance, with the file markers handled as before, when the preference is on, and stripped when it is off. On the 3.0 launcher the flag does forward and stays. The comment on the rule says why. A test uses the real 2.9.6 and 3.0 Flatpak command lines.
* Cut long slicer names to fit the picker (#2595)
With installs listed on their own, a name like PrusaSlicer (Flatpak, master) is wider than its row. The list painted it with no limit, so it ran out of the popup, and the closed selector wrapped it onto a second line. The list now lays the name out on one line that ends in an ellipsis when it does not fit, the selector truncates, and the full name is in the tooltip when it was cut (for a program the user added, ahead of the delete hint). A test checks that a long name is cut to one line within the width and a short one is left alone.
* Keep the 3.0 launcher's flag on a send whatever the preference says (#2595)
A hand run with the single-instance preference off showed the 3.0 launcher needs its flag on a send too, not only on a start: a cold start with a file and no flag loaded nothing, and a send to a running 3.0 left a launcher process that never forwarded. A slicer on the wait table now gets the flag on every launch, as it already did when started alone. The doc comment says why. The preference text, in English, Japanese and Chinese, and the guide now say that PrusaSlicer 3.0 is the exception to turning this off. The tests that took the flag away with the preference off now expect it, for the launcher entry, a bare launcher command and the 3.0 Flatpak line; the test of the send in the UI checks the first send carries it.
* Keep the install-flag swap to PrusaSlicer, found by what it is (#2595)
The swap of --single-instance-on-url for --single-instance ran for any program whose command had the flag, so another program with that flag would have been rewritten. It is now a PrusaSlicer rule: it applies to a slicer recognised as PrusaSlicer by its identity, its id or, for a program the user picked, the name it goes by, never by a version number. The single-instance table uses the same identity check. A test keeps the flag of a program that is not PrusaSlicer, strips it when the preference is off, and swaps it for a picked program named PrusaSlicer.
* Do not promise a hard bound in the wait comment (#2595)
The comment on wait_until said the production probe ends by the limit. Its clock starts after the process is spawned, and killing and reaping the process and scheduling are not bounded by it, so it is a polling and read budget with process overhead on top. The comment says that. Comment only.
* Tell PrusaSlicer 2 from 3 by the installed version (#2595)
PrusaSlicer 2 and 3 need different handling, and the rules had to guess from the command line. Each install of PrusaSlicer now carries its major version, read when it is detected from the release at the top of its appstream metadata and never by running the program: a Flatpak's own files (the branch the command names, else the current one), or the metainfo file beside a desktop entry. PrusaSlicer older than 3 is sent the file with --single-instance in place of --single-instance-on-url, which does not hand a file over there, and is not waited for. PrusaSlicer 3 and newer keeps the launcher's flag, is started on its own, waited for, and sent the file. When the version can not be read, the command decides as before: the slic3r-app-launcher launcher counts as 3, and any other entry is left as it is. A program that is not PrusaSlicer is untouched whatever its flags. Tests use metadata fixtures, no Flatpak: 2.9.6, 3.0.0-alpha10, a branch that is not installed, a system package, an unreadable version with and without the launcher, and a non-PrusaSlicer program with the same flag.
* Make the busctl wait tests steady under load (#2595)
One of them failed once in a full run at its first assertion and passed alone. A script that has only just been written can fail to start (text file busy) while another test forks, and that reads as a busctl that is missing. The fake programs are now started once, patiently, with a flag they answer at once, before a test relies on them; a hanging one uses exec so it is killed cleanly. The time bounds that could trip on a busy machine are several seconds now, and the checks are on outcomes: not ready and keeps waiting, send now, and the number of looks. Thirty runs alone, thirty of the whole slicers filter and thirty of the busctl tests under eight busy loops all pass.
* Say what the busctl reader thread leaves behind (#2595)
The thread that reads busctl output is left to end when the pipe closes. A busctl that answered but left a process holding its stdout reads as slow, and every poll of such a bus can leave one blocked reader behind until that process lets go. A comment next to the thread says so. Comment only.
* Make Save as mesh a plain export (#2595)
Save as mesh asked for the bodies and the format, and could also send the file to a slicer with a checkbox and a slicer list. Sending now has its own command, so the checkbox, the list and the Send label are gone from this dialog: bodies, format, a file dialog, Save. The two settings that only the checkbox used, save_mesh_send and save_mesh_slicer, are no longer kept; a settings file that still has them loads, and they are ignored. The strings only they used are gone from the catalogs. The slicer list stays in the dialog of Open in Slicer. file.save_mesh keeps its slicer parameter for scripts. The guide describes the two as separate.
* Rename Open in Slicer to Send to Slicer (#2595)
The command sends a file to a slicer rather than opening one, and a later Send to App can share the name. File menu, Mesh tab, right-click menus, the dialog button, status lines, the guide and the English, Japanese and Chinese strings now say Send to Slicer, and the command id file.open_in_slicer is file.send_to_slicer. It is new in this change, so there is no alias. The remembered slicer is stored as send_slicer, and the question the agent chat asks says send to. Module and type names stay as they are.
* Put the send targets in one table and one send pipeline (#2595)
The known slicers, the list of slicers with a single-instance flag and the rule for slicers that must be started and waited for were three separate things. They are one table of targets now: id, label, kind, names and program files, accepted formats and the default, how the file is handed over, the single-instance flag, the version from which PrusaSlicer's on-url flag hands a file over, and the wait-for-ready rule. Programs that are not in the table are slicers with the same defaults. The kind is slicer, the only one so far; its comment says it is where a later Send to App would plug in. The send itself is one function: write the bodies, find the target, start it and wait if its rule says so, hand the file over, report. Detection and resolution take a kind. Nothing changes for what already worked.
file.save_mesh keeps its slicer parameter, now through the same function, with its export arguments and result unchanged: a cold PrusaSlicer 3 is started and waited for before the file goes, and it accepts the program path of a detected slicer as file.slicers lists it (file.slicers gives it as program). A path is accepted only when it is the program of exactly one detected target, and that target's own command and arguments run; a launcher several entries share, such as /usr/bin/flatpak, is refused as ambiguous, and any path nobody listed or chose is refused. The parameter and the code say it may be deprecated later in favour of file.send_to_slicer or a Send to App workflow, which is a possibility and not a plan.
Tests go through file.save_mesh itself for the two reported failures, a listed AppImage path and a cold PrusaSlicer 3 that is waited for, with the slicers and the busctl made up; and they check that the result and the file are what an export without a slicer gives, and that a path that is not listed, or is shared by two entries, writes nothing. The pipeline has its own tests: a cold launcher waited for, one already up, wait return, and one that never comes up. A test of save_mesh that shared a file name with another is given its own.
* Keep an AppImage's id through an upgrade (#2595)
When a slicer has several installs, each gets an id made from where it was found. For an AppImage that was its file name, which carries the version, so upgrading it changed the id and the remembered choice missed. The id is now made of the slicer's id, the fact that it is an AppImage and a short hash of its folder, so a new version that replaces the old one in the same folder keeps the id, and the same AppImage in another folder is its own install. Two versions kept side by side in one folder are two installs: while both are there, their file names are added to their ids to tell them apart.
A remembered id is found again only when it names exactly one install. An id that was one AppImage and is now two versions, or a plain id that is now several installs, is treated as not remembered, so the picker starts from the first entry as on a first run and does not quietly pick another install; a single install left of the same slicer is still found, as before. Installs that are not AppImages are told apart as before. An id from before this change no longer matches. Tests cover an upgrade, two versions side by side, a second folder, and the picker's side of each case.
* Add Open with EasyPrint to Send to Slicer
EasyPrint is Printables' slicer in the browser. It's a plain text row in
the Send to Slicer dialog, backed by a new file.open_in_easyprint
command. The command exports the bodies as a 3MF (or STL), hands them to
the host to upload to slicer.printables.com/import, and the app opens the
link that comes back. The desktop app uploads with ureq and the browser
build with fetch, so this is the one send target that works on the web.
The model leaves the machine, so the command refuses without
consent: true, the dialog asks once and remembers, and an AI agent's
request asks first. A model over 100 MB is refused before anything is
sent, and a failed upload shows as an error with the reason.
The chat's privacy note said SolidCraft sends nothing anywhere, which
isn't true any more, so it now says that about the chat. New strings are
in every catalog.

Changing a dimension's value re-solved its sketch as the smallest move from
the stored positions, which splits the change between both ends: a
rectangle side set from 40 to 60 mm grew 10 mm each way. parameters.change
now first solves a sketch whose length dimension (distance, horizontal or
vertical distance, line length) the parameter drives with that
dimension's first point held, and stores the result, so evaluation has
nothing left to move. Where holding it can't solve (a symmetry moves both
ends), evaluation solves as before.

* claim: #4784
* Part properties: one table of keys, each with its scope, check and label (#4784)
SolidCraft's part-property keys (project, part number, revision, author,
organization, description, licence) were declared once but listed again
by hand in each command, error, dialog and window. They are now one
table, metadata::KEYS: each row has the key, where it may be set
(Scope: the design, a component or both), how its value is checked and
the message id of its label. A new key is one row.
Metadata::set is told whose metadata it changes (Owner::Design or
Owner::Component), and a key is taken where its scope covers that
owner. is_well_known, both set commands, document.metadata,
component.metadata, the refusals, the Design Properties dialog and the
Bill of Materials window read the table; the hand-written lists are
gone (WELL_KNOWN, the label match whose fallback named any unknown key
"License", the window's three labels). metadata::BOM_KEYS names, in
column order, the keys a bill of materials lists for each part:
component.metadata returns them, component.metadata.set takes each as a
parameter of its own and the window edits them; a test keeps each one a
row of the table that a component takes. Free properties use the keys'
text rule (metadata::check_text) instead of a copy of it. The params
docs point to document.metadata's properties instead of repeating the
keys.
Every key accepted before still is, on the design and on a component.
Two things change:
- a refused key or a full metadata on a component says "part property"
("`bogus` is not a part property: …", "part properties are limited
to …"), not "design property";
- changing the design's own properties no longer evaluates the model.
The fields that change no geometry are named once,
Document::with_part_properties_of: the design's metadata, and each
component's metadata and free properties. It compares them first and
copies the design only when one differs, as before.
The shortcut is for a session's own edits only. A command that gives
the session another design (doc.open, file.new, doc.recover: through
Session::replace_design, which now counts them) is refreshed in full,
however little the new design differs from the one before, so its
joints are solved and its occurrence state pruned. Before, opening a
design that differed from the open one only in render settings or
component properties skipped that; with the design's properties in the
list it would have for two revisions of one part too.
Tests: the table (one row per key, the dialog's order); the bill of
materials' keys (rows a component takes, in column order); each scope
on each owner, and refusals that name the owner (the empty key, an
unknown key, a 256-byte key shown cut); the text check at 4096 bytes,
line breaks, tabs and control characters; hostile keys and values
refused without a change; only-part-property changes in each scope,
and changes beside them (units, a component's name, an added, removed
or swapped component); document.metadata.set, remove, undo and redo
evaluate nothing; opening a revision that differs only in its author
solves its joint; the component wording, the shortcuts and the limits;
the dialog's and the window's labels from the table.
What the tests can't reach: every row is Scope::Both, so a known key
refused for its owner (the wrong-owner branch of check) can't happen
yet. It becomes live with the first single-scope row, bom_type, a
component-only key.
Left for later (not this topic):
- Metadata::others() ignores scope, so a component-only key stored on
the design would be neither a dialog field nor listed under other
tools' data. It matters from the first single-scope key (bom_type).
- assembly.bom's rows, its CSV columns and the window's grid headers
still name the three keys by hand; the bill of materials module's
rewrite will read BOM_KEYS.
- The bill of materials types (P1, #5107, into drawings) still use
WELL_KNOWN and the two-argument set: once this is on main, bom_type
is rebuilt on it as one KEYS row with Scope::Component, set through
Owner::Component.

* Sketch pattern: a spacing arrow dragged past zero gives a negative spacing (#5497)
The drag arrow floored an unsigned value at a small positive number, and the
rectangular sketch pattern's two spacing arrows were unsigned, although the
command takes a negative spacing and typing one works. Both arrows are signed
now, like the Extrude, Move and offset ones.
The test drags each arrow back past its start: without the change the first
one stops at 0.001.

* Drag arrows: the solid pattern spacing and one-sided sketch offset go negative too (#5497)
The solid rectangular pattern's Spacing arrow and the sketch Offset distance
arrow were unsigned, so a drag back past the start stopped at a small positive
value, although both commands take a negative value and typing one works. Both
are signed now. A symmetric offset uses only the distance's size, so its arrow
still stops at the curve.
Tests: the solid pattern arrow dragged 10 mm back gives Spacing -10 and the
copies on the negative side (without the change: 0.001); the offset arrow
dragged across its circle gives -1 mm and the same circle as typing -1 mm
(without the change: 0.001), and a symmetric offset stays positive.

* Release: sign the Windows binaries and MSI through SignPath Foundation
When the SIGNPATH_API_TOKEN secret exists, each Windows job sends the
three .exe files to SignPath before packaging, then the MSI built from
them, using the GitHub artifact flow from SignPath's docs. The policy
is test-signing unless the signpath_signing_policy dispatch input or
the SIGNPATH_SIGNING_POLICY repository variable says otherwise. Without
the secret the jobs build unsigned exactly as before.
package.ps1 gains -Phase stage|package so signing can sit between the
build and the MSI; the artifact configuration to paste into SignPath is
packaging/windows/signpath-artifact-configuration.xml.

* Placement handles: shared module, with Rest as the first tool
The Rest handles spike becomes a shared module, place_gizmo, so other features placed on a face can
use the same marker and knob. The mechanics (crosshair with its three states, the grab offset, the
footprint while dragging, the turn knob) live in place_gizmo.rs. The handles own the pointer through
canvas::owns_pointer, as the move triad does, so navigation and Select Other's press-and-hold leave
them alone. Each tool is one file under place_gizmo/ that gives a Spec: which dialogs it serves,
which commands' Position input also takes sketch points, where the place is, how the pointer
re-places it, its footprint and its turn, if any. The module lists the tools one per line, so tools
added on separate branches each add one `mod` line and one list line. Rest is the first.
The handles are always on; the preference the Rest spike had is gone. The POINTS accept flag on a
Position input is granted from the tools' Specs instead of a Rest-only arm in the plastic dialog's
start. Handles are published as `rest:position` and `rest:rotate` as before.
Seen straight down, the dialog's height arrow collapses onto the place and its value box sits just
right of it, where it took the press meant for a knob pointing that way. The knob now slides out
along its ray until it is clear of the box.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Placement handles: Boss
The marker moves a boss across the model, also from Edit Feature, and its Position input takes
sketch points while the handles are on, so a screw boss can be dragged onto the centre of a
circle drawn for it. A boss is round, so it gets no knob; the footprint while dragging is its
outer circle. Published as `boss:position`.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Placement handles: Snap Fit
The marker moves a snap fit across the model and its Position input takes sketch points while
the handles are on, so the arm can be put where a sketch says (#3423). The knob points the
catch: it turns between the four directions the Catch Direction combo offers for the face, so
the knob and the combo always agree; the command keeps only those four, so there is no free
turn. The footprint while dragging is the arm's foot, its thickness behind the place and its
width across. Published as `snap_fit:position` and `snap_fit:rotate`.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Placement handles: the look in one file
Everything that draws the handles (the crosshair and its three eased states, the knob's ball, the
cased lines, the angle label, the colours) moves from place_gizmo.rs into place_gizmo/look.rs, so a
restyle touches one file and the mechanics (hit radius, drags, knob geometry) stay where they are.
No change in behaviour.

* Placement handles: behind a Design preference, off by default
The handles sit behind Preferences > Design > Placement > Placement handles (`placement_handles`,

drawn or published. The tests switch the preference on; one checks the default.

* Placement handles: the move marker as designed in the prototype, drawn with theme tokens
The marker is a dot with four arms to the screen cardinals: short and dotted at rest, longer with open arrowheads when pointed at, solid while dragging, each state growing out of the previous one (360 ms). Sizes are the prototype's. Its core is the icon highlight and its casing the marker halo, the tokens main's hole handle uses, so the literal allowance goes. The tip shows while pointing, not during a drag.

* Placement handles: the dialog's drag arrow stands above the move marker
With the handles on, the Height arrow started at the marker's centre and ran through its upper arm, head on arm tip. The arrow now keeps the marker's full reach and a gap free at the base, its shortest length grows by as much, and the base dot is left to the marker. Other dialogs are unchanged (clearance zero).

* Placement handles: a turn ring on the face replaces the knob
The ring lies on the face about the move marker's centre, drawn in perspective, a fixed 65 px on screen like the move triad's arrows (it is a control of something on the screen, not a measure of the model). At rest it is a short dotted arc with an open chevron grip just outside; pointed at, the dotted circle opens from the grip both ways round and the grip slides in and fills; while turning, a solid arc around the grip. Dragging the grip turns the feature as the knob did, through the same handle name, so the harness tests stand.
The floating value box yields: with a handle's centre under it, it moves to the other side of the arrow's tip or above it, since seen straight down the box sat exactly where the grip is. A handle the arrow's stem crosses keeps the pointer.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
* Placement handles: a compass while turning, and the turn pulled onto the face's compass points
Four ticks just outside the ring at the face's in-face world directions (the ones the Snap Fit combo names, +X, −Y, …) appear while turning and stay put, so you can see how far you have gone. A Rest's turn is pulled onto one of them within 8°, otherwise it steps by 5° as before; Alt or Ctrl frees it. The readout beside the grip names the point it sits on ("90° · +X") and keeps clear of the ring.

* Placement handles: the footprint in the preview's blue, the idle handle steps back
The footprint drawn while the marker drags is a filled shape in the preview's own blue with a thin darker edge, not a white outline, so white stays reserved for what can be grabbed. While one handle is dragged the other fades to a quarter and comes back when the drag ends.

* Placement handles: the ring in the preference text, the docs and the tests' wording
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
* Placement handles: the look as tuned in the app
Marker: drawn to the redrawn design (dot r 3.9 pt, two dashes per arm, a filled head 8.7 × 7.1 pt whose base is where the outer dash began); pointed at, the outer dash becomes the head (its far end narrows to a point, its near end widens); dragging runs the inner dash on into the head as a shaft. Every casing is 0.4 pt outside the edge, for lines, heads and the dot alike.
Ring: the grip and the compass lie in the ring's plane like the circle, so the grip is never skewed against it; the grip is a thick chevron with a hole that flattens into the base as the grip slides onto the ring, and fills; the dotted circle stays while turning, with the solid arc laid over it; opening eases in and takes 0.3 s, leaving is a 0.15 s fade over the resting ring, not the sweep backwards; a drag keeps the angular gap of the press, so the grip does not jump onto the pointer; the compass ticks and the readout's point name are in their axis colours, and the grip takes the axis colour (eased) while aligned with one, with that point's tick left out; free turning keeps a hair of pull (0.5°) so an axis can still be hit; the readout wraps to a half turn.
Value box: with a ring it keeps out of the circle the ring, grip, compass and readout sweep, one place per view, nothing moves when a turn starts; also when the value does not evaluate and there is no arrow.

The animations the handles grew (a factor eased in and out each way on its own time and easing, a handle stepping back while the other works, a colour that comes and goes from the last one it was on, the gap a press keeps for its drag, an offset that slides instead of jumping) move out of place_gizmo into motion.rs, so the next manipulator reuses them. The look's timings become Transitions in look.rs. No change in behaviour: the contact sheet before and after is identical, the harness tests stand.

* Axes and points from circular edges and round faces
In 3D, a round edge or face stands for its circle wherever a command
takes an axis or a point.
Revolve, Surface Revolve, both Circular Pattern dialogs, Plane at Angle
and Move -> Rotate take a circular edge (through its centre, along its
normal) or a cylinder, cone or torus face (its axis). The features keep
the pick as a model reference, so they follow the model when a parameter
moves it. Straight edges work as before; flat faces are refused.
Every 3D point input takes a circle's centre: construction points (which
follow the circle), To Object, patch points, hole placement, and Move's
pivot and points. Hovering shows the axis as a dashed construction line
or the centre as a star, and the dialog's chip names what the pick
stands for ("centre of edge 10", "axis of face 3").

placed the same way), as the viewport and the other round picks do.

Sketch (New Sketch), Create (Frame Member) and Configure (Parameters,

With a section shown, the marking pass decided where the cap shows (the stencil) and wrote the
depth everything after it tests against. #1768 gave it the faces' FACE_BIAS for the second job,
so edges draw over their own faces (#1434). For the first job its slope part is unfair: next to an
edge where a back face seen through the cut meets a front face, the front face won a band about a
pixel wide although the back face is nearer. The cap skipped that band, and the edge line showed
through the cut.
#6363 marked those samples again from the back faces, pulled toward the eye as far as FACE_BIAS
pushes. That closes the gaps beside the edges, but the pull also lets back faces win wherever they
lie within the push of a front face, along every body's far silhouettes, and the cap hatches that
band. On bherbruck's block, the band away from the cut went from 58 px orthographic and 534 px
perspective before #6363 to 618 and 780 with it. In the app, his filleted hub showed it in every
frame of a 36-step orbit in both projections.
This replaces that pass. While a section is shown the opaque model now draws in four steps (`Cut`):
1. mark: the faces by their true depth (no push): colour, the stencil and depth;
2. a triangle over the viewport sets the depth back to the far plane, colour and stencil kept;
3. push: the faces again with FACE_BIAS, depth only, so the depth is what unsectioned frames have
and edges draw over their faces as before;
4. cap: depth only, as #6728 made it; the mark pass has drawn the cap's colour and hatch, as fs_solid
draws a back face seen through the cut.
The window pass's depth reset and this one are one helper, `depth_reset_pipeline`, for either
depth direction, and its passes are built by #6728's `solid_writes`. Unsectioned frames are unchanged. The CPU rasterizer already chose the cap by
true depth.
Tests (crates/gpu/tests/depth.rs), with the device's float depth and the 24-bit fallback:
- a_cut_hides_the_edges_behind_it (new): bherbruck's block cut at y = -16, home view, orthographic
and perspective. No edge shows through the cap, and away from the cut the picture is a box of
just the kept part's: 0 px orthographic and 1 perspective (main: 618 and 780).
- bherbruck's pocket and hub tests from #6363 are kept and pass (pocket 0 px; hub 1 and 2 px over
its twelve views, as with #6363's pass).
- an_edge_on_a_face_draws_whole_at_any_angle and
an_edge_just_behind_a_face_stays_hidden_on_a_large_design also run with a section shown.
In the app (safe mode, WARP), with 625 patterned cylinders cut by a section, the frame time is
that of main (#6363): 33.5 against 34.3 ms at the home view, 34.1 against 35.2 ms with the model
filling the view.

* Face pick by point: linear work budget, so bodies with many faces take a sketch (#6720)
A face picked by its point alone charged the whole mesh once per face, and
face_contains scanned every triangle for each candidate. A block with a
modelled thread (about 5 000 faces) went past the 2 000 000 limit. The
triangles are grouped by face once, each face's test reads only its own,
and the budget charges triangles + faces.

* Sketch Dimension: value box in the design's units (#3812)
A dimension added without a value restated what it measured as
"<value> mm", whatever the design's units. In an inch design the
Dimension tool's value box therefore opened at "25.4 mm" next to a
dimension whose text read 1.000 (inches).
Document::design_length writes a measured length in the design's units
("1 in"), with enough decimals to keep it to the micrometre, so a
dimension that restates the geometry still moves nothing. The Dimension
tool, AutoConstrain's dimensions and Toggle Driven (making a driven
dimension driving) use it. Millimetre designs are unchanged.

The evaluation cache's 64 MB budget charged every cached feature result the whole model, though a
state shares every body it did not change with the state before it. A design whose model is a few
MB kept only its last few dozen results, so setting a parameter back recomputed what had dropped
out. Each result is now charged for the bodies and sketches it does not share with the state it
started from.

`Session::replace_design` swapped in the fresh session without its

So `file.new`/`doc.open` never recorded how they ended, the commands sent
after them in the same frame (a control-channel or MCP batch) were not
journaled, and a crash report then named `file.new` as the command in
flight. `replace_design` now keeps the flag, like the other session-wide
fields it keeps; only the design on screen has it set.

* claim: #6917
* Tests: the six timing assertions do not depend on the wall clock (#6917)
Six tests asserted on the wall clock. Their result depended on how loaded
the machine was and not only on the code under test: they passed on an idle
machine and failed when the test binaries ran beside each other, which is how
the suite runs (`cargo xtask test` starts every test binary at once).
CONTRIBUTING.md:196 says it: "Tests run beside each other on a busy machine,
so a test must not depend on wall-clock timing."
The change is confined to the six test files the issue names:
- geom: the tangent chain of a helix is a ratio (750 pieces against 3 000)
instead of a limit of 200 ms.
- io: the placement budget is spent inside the reader, so the clock is gone.
- ui-egui: the classification of many faces is a ratio (900 against 3 600)
instead of a limit of 10 s.
- engine: the clearance measurement drops its 30 s limit; the boolean that
gives up reports itself.
- engine: the fillet beside a modelled thread is a ratio (a 1 mm thread
against an 8 mm one) instead of a limit of 30 s.
- ui-egui: the window frame budget goes from 250 ms to 20 s, the limit #6072
gave its own probe.
The helper is the one #649 wrote, copied into the crates that need it, with
the noise of a run as a parameter.

* test: a copied body must keep the look of the body it came from
solid.move with copy: true leaves the copy without the appearance, the
material or the face looks of the source body, so it renders with the
default look. The tests fail for that reason: the copy has no entry in
appearances.bodies, in materials or in appearances.faces.
* fix: a copied body keeps the look of the body it came from (#6423)
A move with `copy: true` pushed a new body but left it with the default look, so the copy came out a different colour than the part it came from. The copy now carries the body's appearance and its material, as the component copy already did.
* test: keep the copy regression to the body look and the material (#6423)
* test: each copied body keeps the look and the material of its own source (#6423)
Two bodies with different appearances and different materials, copied in one solid.move: each copy must keep the look and the material of the body it came from.
Scope of the fix: the look of the BODY and its material are carried over to the copy. The per-face looks are NOT carried over: a face look is keyed by the point on the face, so the copy's faces would have to be matched and their points translated, which is a separate feature.
A drag that isn't live walks to the cursor in steps, each a held solve
on its own budget seeded on the last solved state. Past a failed step
the walk keeps trying every step (a stretch the geometry can't follow
can be followed by one it can), and each failing solve runs the
numerical solver to its limit: one drag in a 65-command sketch took
7.7-9 s, most of it in failing solves.
A failed step leaves the sketch as it was, so the steps after it all
start from the same state and none changes what the next one sees.
They are now solved eight at once on all cores; those that fail in a
row are taken as tried and the walk goes on at the first that doesn't,
as it would one by one. The drag above takes 3.7-4.3 s and every
command's reply is unchanged. Live frames, whose steps share one
frame's budget, are left as they are.

* Sketch: an offset slot can still be moved by the dimension that places it (#6569)
An offset arc is drawn round its source's own centre, and its ends are
held while the sketch solves (the offset is rebuilt from its source
afterwards). Its arc condition, both ends as far from the centre, then
only tied that shared centre, and the source arc with it, to the middle
of the held ends: a slot offset by 1 mm lost a degree of freedom, and
the length that places it was refused as conflicting.
The solver and the constructive reading now leave out the arc condition
of an offset arc round its source's centre (Sketch::offset_arc_follows_source),
as #4466 did for the Parallel between an offset line and its source. The
source's own arc keeps the centre; nothing changes without an offset.

A rectangular, circular or path pattern of an extrude cut through sheet metal was refused
("this sheet machining cannot be preserved in its flat material"), though the cut itself is
kept as a cut-out of the flat pattern. The pattern replayed its copies through the generic
boolean, whose sheet check refuses any change the sheet model can't keep; the cut goes through
the sheet's flat machining first.
Each copy of an untapered extrude cut is now machined into the sheets the same way, in its
moved sketch plane (a moved copy keeps the extrude's prism certificate), and then cut from the
other targets. A copy that meets a folded bend is refused as the cut is there. Mirrored copies
(the sketch plane turns over) and patterns of an intersect (which cut with the union of their
copies) keep the generic path.

* claim: #5853
* Batch: refuse a step that would fail at its turn before the first step runs (#5853)
engine.batch and the MCP batch tool checked only a batch's shape up
front. A misspelled command id in a late step was found at its turn,
after every earlier step had run, and then all of it was rolled back: a
160-step batch with a typo as its last step ran for a minute and
changed nothing.
solidcraft_engine::batch_preflight::check finds, before anything runs,
the first step the batch would certainly refuse at its turn: a step
without a command, an unknown command id (the error names the closest
ids, as at the step's turn) or, with strict parameter checking, a call
that breaks its command's typed contract. Anything that depends on the
design is left to the step's turn.
- engine.batch (control channel) checks against the app's registry and
its session's level; view.pick, which the app answers itself, passes.
- The MCP batch tool checks when the commands run in its own process
(headless, with --param-check from the backend). A running app may be
another version with other commands and checks the batch itself; its
reply's not_run is passed on.
- The refusal is the failing step's reply with completed 0, undone 0,
not_run listing every step and a note.
Tests that used an unknown command only to make a late step fail now
use a step that fails at its turn (a bad extrude distance), so they
still test rollback, timings and file.new as before.

Holes picked on parts are rarely exactly in line. A closed loop through
axes a few hundredths of a microradian apart (a lever, link and a rod on
a cylindrical axle) can't close exactly: it closes to nanometres, and the
gap grows as it turns. The loop solver wanted 1e-7 mm, so it threw such a
closure away (the loop stayed open, its parts at 0 dof) or stopped a drive
or drag after a fraction of a degree.
The conflict check is now 1e-4 mm / 1e-6 rad (it was below what its
message can show), and joint.drive / motion and joint.reach close the
loop at each step as at the start: to the tight tolerance where they get
there, otherwise within the conflict check.

* Body rename: an imported assembly's other bodies keep their names and components (#2175)
An Import keeps its body names by the file's body index, and builds no body for the
file's later instances of a repeated part (`skip`). Renaming a body stored the names by
the body's place in the model instead, so every name after the first skipped instance
landed one slot early (and the new name could land on a skipped slot). The rename looked
right until the design was rebuilt; then those bodies took other names, dropped out of
their components and showed up loose in the import's top component.
`Feature::body_name_slots` maps the bodies a feature builds to their stored slots, and
`Feature::pin_body_names` stores current names through it. The rename, the pinning of
later features' names (rename and suppress) and `Document::body_rename_from` use them.

* claim: #6646
* Control channel: document.revision, a design revision and a document id (#6646)
A program that follows the open design asks document.revision and exports
only when the answer moves: document_id names the open design (kept through
edits, saves and renames, another for each design started or opened, never
shared between two tabs or two runs) and revision moves whenever the design,
what is hidden or an uncaptured component position changes. It stays put on
reads, selections and view changes, unlike the session's view revision.
The revision is read lazily: the session remembers the design it last
reported (held weakly, so Arc::make_mut can never change it in place and its
address can't be reused) and takes a new number from one counter for the
whole run when the design is another one. The control method answers at once,
also while a slow command computes; engine.execute reaches the same command
for scripts and MCP.
* document.revision: hash the run's id prefix with the process's random keys
A clock set before 1970 gave every run the prefix 0, so a restarted app could
answer a new design with the id and revision of the old one. The docs no
longer promise an answer at once: a screenshot waiting for an opened design to
be meshed still holds the requests behind it.
* document.revision: its label in the complete catalogs (ja, zh)
* claim: #6985
* Control channel: control.subscribe and design.changed events (#6985)
A connection that sends control.subscribe gets the active design's id and
revision in the reply (as document.revision answers), then a
{"event":"design.changed","params":{document_id, revision}} line whenever
either changes, so a live link need not poll.
The window publishes the design at the end of each frame's logic and
drawing while a connection is subscribed (one atomic load otherwise). Each
subscribed connection waits on that from a thread of its own and writes
the latest after a 100 ms gap, so a burst of changes is one line. Replies
and events share one lock per connection, each written whole (#6390).
* control.subscribe: the reply before any event, a second one refused
The events thread started before the subscribe reply was written, so a
change right after the window's answer could reach the client before the
reply that named the older revision. The subscription now starts holding
the connection's line lock and writes the reply under it.
A second control.subscribe on a subscribed connection is refused on the
connection itself: its answer could arrive behind a newer event. When no
thread or socket is left for the events, the reply says it did not
subscribe instead of ok.
* control.subscribe: a second one does not lose a finished late reply
The already-subscribed answer came before the busy check, so a request that timed out and had finished since lost its reply: control.pending then said the app ended it without one. It now comes after the busy check and drops a finished late reply as every other request does.
* control_server: declare the subscribe guard at the top of the loop

A line tangent to an arc at the arc's end had no sense: the tangency held
with the line on either side of its touch point, so pinning a line's far
end across the corner left the line cutting back through its fillet, and
when the solver found the mirrored corner the arc kept its stored
direction and became its three-quarter complement, inside out.
The solver now keeps each fillet an arc of its corner. A line tangent at an
arc's end keeps its sense there (it leaves the arc as it did) and the arc
its side of its chord, compared with the positions before an interactive
move or the stored ones. A corner that mirrored gets its arc on the
mirrored side: its ends swapped where the solve ran the arc round the
other way with the lines following, or the arc reflected across the line
that stayed and solved again where a line cut back through. A solve that
would loop the arc the other way round, or fold a line onto it, is refused
as a fold is. A drag's cursor-following steps keep the fillets too, so a
line dragged through its own fillet stops at the arc.
The kit slider adds a real `egui::Slider`, lets egui paint it, then paints an
opaque rectangle over it and draws the kit's track and thumb on top. That mask
was exactly `slider_width` wide, and egui places its handle so the circle's
right edge lands on `rect.right()` at the maximum, so the fill stopped flush
with the handle and its last column survived as a light sliver beside the
value box. The kit's own thumb cannot hide it either: its radius is
`t.space_8` while egui's handle radius is `input_radius`, about two pixels
larger.
Extend the mask one pixel past its right edge. The gap before the editor is
`item_spacing.x`, so nothing else is covered, and only the maximum was
affected: at the minimum the handle's left edge coincides with the mask's left
edge, which a fill does cover.

* Sketch display: each sketch samples within its own budget (#6524)
After a large DXF was inserted, lines drawn in a later sketch vanished
once finished: only their end points showed and could be picked, and
hiding the DXF sketch brought them back.
The display cache had one sampling budget for every shown sketch (4096
curves, 131 072 vertices per model state and view). Sketches are drawn
and picked in timeline order, so a large imported drawing used it all
and every later curve came back empty (BudgetLimited): not drawn, not
pickable, while the points, drawn separately, stayed.
Each sketch now has its own budget with the same limits (curves,
profiles, vertices and nodes). The cache as a whole is capped at 65 536
curves and 16 384 profiles, so memory stays bounded however many
sketches are shown.

* Context menu: the Appearance flyout closes when the pointer moves to another row (#6657)
Hovering Appearance opened its quick-choice flyout, but resting on a plain
row of the same menu never closed it: only another submenu row replaced it.
Now a flyout closes once the pointer moves onto another row and rests there
for 0.3 s, so a diagonal path to the flyout across a neighbour keeps it open.
A flyout opened with the keys stays open while the pointer is still.

A feature's face points are moved onto their named faces before it is
evaluated, so a To Object extrude follows its target face when an earlier
feature moves it. A pattern's or mirror's copies were built from the
feature as stored, with the face where it was picked: after a gear's disc
was made thicker, the tooth reached the new top but its pattern copies
kept the old height. The copies now use the same moved points; the move
is one helper used in both places.

* Test: sketch Intersect keeps its exact cuts, crosses curved faces on the surface, cuts on a top face
Intersect's cut of a box, a cylinder, a sphere and a tilted cylinder, as it is on main, pinned.
Two cases where it is not exact: a plane through a cylinder's rim cuts the mesh's chord (its sides
come out at 6.3159 and 6.3085, not the square root of 40; a hole's walls at 25.0122), and a plane
on a body's top face finds nothing ("projects to nothing on this sketch plane").

* Sketch Intersect: crossings on curved faces lie on the surface; a plane on a top face cuts it
Problem: the plane cut that sketch Intersect makes of a body's mesh (project::section) took a
crossing on an edge where a curved face meets another (a cylinder's rim on its cap) from the
merged normals, which are undefined at the crease, so it fell on the chord: a cylinder's sides came
out 0.01 mm off and uneven. A plane through a vertex or on a face counted the vertices on it as
below, so a plane on a body's top face crossed no edge and found nothing.
Solution: the crossings are found by section_segments, which section fits as before: an edge where
a curved face meets another takes the curved face's normals, so the crossing lies on its surface;
a vertex within 1e-9 x the mesh's size of the plane is on it, on one side for every edge (below
when the mesh lies on or above the plane, else above), and an edge ending there crosses at that
vertex, which is an exact point for the fit. Each segment keeps its B-rep face, for a section that
groups them by face. Cuts that were exact are unchanged.

The first test in each GPU path shard compiles the path pipeline cold
on lavapipe (335-502 s on 16 vCPU, 665 s on 8, against the 600 s setup

cache on a sticky disk that main commits, so the first test reads it

A change computed off the window thread ran here with only the results of the evaluation
ahead's last evaluate primed. A parameter change evaluates twice (before and after its sketch
stores the new solution), so its first evaluate here found nothing to take, and on a design whose
states pass the evaluation cache's budget it recomputed the features on the window thread: the
window froze for seconds after Computing ended. The run now also takes what the evaluation ahead
kept (KeptResults, as an agent's control requests already do).
The catalogue entry Quantity served both the pattern dialogs' number of
instances and the motion study's plotted quantity. Nine locales had
translated the second meaning, so the rectangular pattern dialog showed
e.g. "Größe" above "Anzahl 2" in German.
The motion study's row now reads motion.plot_quantity (a pending file
that keeps every locale's previous word there). Quantity takes each
catalogue's own ui.quantity text, which the "Quantity 2" row already
shows; nothing is newly translated. The glossary lists Quantity under
words with more than one meaning.

On 8 vCPU the first merge-queue run after #7066 failed: one gpu path
test went past the 600 s pipeline-setup budget (665 s; 204 s for the

The 108 gpu path:: tests run one at a time (gpu-path test group) and took
about 36 of Native Linux tests' 45 minutes in a merge-queue run. They now
run in a GPU path tests job, three hash partitions on 8 vCPU, beside the
other tests; Native Linux tests leaves exactly them out. A `gpu` output of
Select checks drives both the job's `if` and the `ci` check.
The Windows jobs now run in a merge group only when its diff reaches what
they exercise (the pull request patterns and the Cargo.lock graphics-stack
check), not on pushes to main, and still nightly and by hand.

SolidCraft runs through XWayland whenever an X display is available. A
compositor that doesn't let X11 apps scale themselves draws the window at
100 % and stretches it. docs/nix.md said so only for fractional scaling,
but GNOME 47 (RHEL and Rocky Linux 10) does it at any scale: the report
shows 1.05 physical pixels per point at 200 %.
The troubleshooting page gets a section with the cause, the Window system
preference, SOLIDCRAFT_WAYLAND=1 for 0.21.0 and earlier, and the file drop
trade-off; docs/nix.md links to it.

* claim: #4214
* Viewport: the grid fades with the distance instead of cutting off (#4214)
The ground grid stopped at a fixed distance from the view, so its edge showed
as a cut across the picture. It now fades out with the distance from the
middle of the view, and it is gone before either of the two lines that used to
cut it: its own edge, and the picture's far plane.
Each grid line is drawn in pieces, and each piece is as faint as the fade
makes it at the distance where it lies. The 'under' batch is drawn by the
overlay pipeline with alpha blending, so the colour's alpha reaches the
frame.
* The headless grid fades with the distance too (#4214)
The headless path (solidcraft-cli snapshot, the home-page thumbnail, the MCP
screenshot) drew the grid from the engine's palette, where a line had no
alpha: the grid still ended in a cut, and at a low camera angle the cut was
in the picture.
A SceneLine now carries an alpha, the CPU rasterizer blends with it and the
GPU capture passes it on, so the engine's grid can fade. The fade itself
moves to the engine, next to the grid's other geometry, and both paths use
it: the headless grid now reaches as far on the ground as the view is wide
(the ground stretches as it is seen at a slant) and dissolves into the
distance instead of ending in a line.
* Fix the headless/viewport grid fade divergence (#4214)
The engine stretched the grid's size with the slant of the plane it is seen at, the viewport stretched it only on the ground, so on a sketch's plane the picture's grid reached further than the window's (153.42 mm against 120.00 mm). Both now share one grid_ext, which the picture and the window draw the same grid from.
* The grid fades out before the picture's far plane cuts the ground (#4214)
The window's grid faded against a far plane of its own: the scene's radius
clipped by the projection's camera (260 mm away at 400 mm of distance), while
the picture itself cuts the ground at the far plane of its own projection
(223.7 mm at the same distance, because the projection frames the scene's
bounds and not its radius). The grid was still a third of its strength where
the picture cut the ground, so the cut showed as a straight line across the
view.
The fade now ends at the far plane the picture's projection uses, and the
grid is gone before that plane cuts the ground.
The test that watched the fade now measures the ink of each row of the
picture, and checks that the grid is already gone in the ten rows above the
row where the far plane cuts the ground: the point it compared before lay
beyond that plane, where both renders draw nothing at all, so the comparison
was always true.

The reviewer asked for the pictures to be attached to the PR (or in a gist),

* docs: say how to attach a picture, and what a gist is for
The review of this pull request pointed at two things in the note on

- Attaching works in the browser for anyone who can comment: drag the
file into the comment. The limit is the command-line agent, whose
upload needs write access to this repository. Say that, instead of
claiming that a contributor without write access cannot attach a file.
- A gist suits a log or another text file; it does not render a picture
inline. Say what it is for, so nobody hits that dead end.

unchanged.

The Joint dialog kept a round edge (a hole's rim), a straight edge and a
corner as plain points where they were picked. When the part got thicker,
a hole moved or the part got longer, the origin stayed where it was and
the jointed part overlapped the other one. An edit that left the picked
spot where it was (lengthening an arm away from the jointed hole) looked
fine, which hid it. Faces and hole walls were already found by name.
The dialog now sends a round edge as its circle's centre with its z, and a
straight edge or corner as an edge pick with its z. The engine keeps them
by name (the round end by its wall and the face across its rim, the edge
and corner by their edge and face names), with the frame the pick showed;
where it can't (no planar face beside the edge, no names), it keeps the
point as before. Edge origins get an optional axis (along the edge, or a
fixed direction) so a hinge on an edge keeps turning about it.
Tests: every joint type and as-built, for each way the dialog picks an
origin, with the arm made thicker, its hole moved and the arm lengthened,
inside one design and through Update Links.

* Move and Align on placed components: picks and vectors where they are shown
A body in a component placed away from its own frame (an imported part
set upright) moved the wrong way: Move's vector, axis and pivot were
taken in the root's frame, so moving the upright plate up moved it along
its own frame's z. They now turn with the frame of the bodies moved.
Align mapped each pick into the frame of the body under it, so aligning
two separately placed parts mixed two frames (the plate landed at right
angles), and its snap points were never mapped at all. Align now finds
its picks, face normals and snaps where the view shows them and takes
both ends into the moved bodies' frame.

Extrude, revolve and the primitives preview their tool on its own. That

active) the tool showed at right angles to the picked face, though the
feature itself came out right.

* Every new command comes with input and output schemas
A test fails for a command without a contract or an output type, unless it is a planned!
placeholder or listed in schema/unconverted.txt, which holds the 400 commands that predate
the rule and only shrinks: the test also fails when a listed command has its schemas, when
the list names a command that doesn't exist, or when it isn't sorted.
`checked!` now takes only the command's id and checks the contract that id publishes
(`run_checked_as`), so the contract enforced is always the one described. Another test runs
every command that has a contract in strict with an unknown key, so a contract is never
published without `checked!`, under the command's own id, enforcing it.
A new book page, Command schemas, explains how to write a contract and a reply type, the
tests to add, the shared field types and how to add one, with a checklist; the failure
messages point to it. "Adding a command", CONTRIBUTING.md and AGENTS.md now include the
schemas, and the MCP tool description and docs/mcp.md no longer list the converted commands.

* Viewport theme: a light 3D view in a dark window, and the reverse (#4146)
Preferences › Interface › Theme gets a Viewport row under the theme tiles:
Follow theme (the default, as before), Light or Dark. Light or Dark draws
the 3D view in the built-in Light or Dark theme's colours whatever the
window uses, so a dark window can show the model on a light view and the
other way round; it works with every theme, theme files included.
The view takes the background and grid, bodies, selection and hover, the
origin, previews, sketches with their dimensions and glyphs, the navigation
cube and triads, box selection and the analysis colours. Panels, dialogs,
menus and the chips over the view keep the window's. Text and warnings drawn
straight onto the view (the sketch status line, the loose-end and midpoint
markers, the section's cut outlines, the 3D sketch tool and the sketch tools'
previews) take the view's side, so they read on its background.
theme::ViewportTheme is the setting (saved as `viewport_theme`: theme, light
or dark; an unknown saved value reads as Follow theme, as ColorVision's
does). Tokens::get() takes the view's colours from the other side only when
the view's dark or light differs from the window's; Tokens::view() is the
view's side for colours drawn onto it. The ground shadow follows the view
(the scene and highlight caches already key on the colours themselves),
ui.render draws in the view's colours, and ui.prefs takes `viewport_theme`
and reports `viewport_dark`. An older release ignores the setting and draws
everything in the theme.

* Sketch Dimension: arc length from an arc and its end point (#754)
The arc-length dimension existed (sketch.dimension type arc_length) but
the Dimension tool could only give an arc its radius. An arc and one of
its own end points, in either order, now dimension the arc's length:
click the arc, then its end. The pair was refused before ("cannot
dimension that combination"), so no existing result changes. A point
where the arc's end is (a coincident line end) counts as that end.

* Sketch: hovering a circle's edge wakes its centre
A circle's or arc's centre was hard to take with Line or Dimension: it is a small
point in the middle of empty space, taken only within 8 points of the pointer, and
nothing showed where it was. Hovering a circle or arc of the sketch being edited
now wakes its centre: drawn (a cross in a ring) and taken from 16 points away, so
the pointer can go from the edge across the inside to it. Hovering another curve
or point puts it back to sleep, as does leaving the sketch.

* Browser: surface bodies get the surface icon in the Bodies folder (#4165)
Every row in the Bodies folder had the solid body icon, so a surface (an
open shell, such as a Surface Revolve of an open curve) looked like a
solid. A body whose shell does not close now shows the existing surface
icon; solids keep the body icon.
Body::is_surface walks every shell's edges, so ModelBody caches it once per
body (shared by clones, like outline_bounds) instead of the browser
checking it every frame.

* Warn when Ollama models lack tool support (#4846)
Check Ollama model capabilities in the background and cache results per
endpoint and model. Show an advisory warning for models without tools,
expose it through ui.agent_chat, and document the behavior.
Cover capability parsing, warning selection, background probing, caching,
and selection changes with synthetic regression tests.
* Keep the Ollama capability probe out of the web build
The panel never calls it there, so it would only be dead code.

solid.loft already closes to a point (a section {sketch, point}), but the Loft
window's Profiles input took profiles only, so a pyramid or cone tip couldn't
be made from the UI. The input now also takes a finished sketch's point, sent
as an apex section in pick order; profiles of one sketch still make one
section.

* claim: #5543
* Extrude: a profile drawn twice is cut once, not as two coincident tools (#5543)
A circle drawn twice at one place is two profiles of one region. Extruded
together they were two coincident tools: a cut through a 121-hole grid with
four such circles retried the boolean with the tool nudged (four times) and
took 25 s instead of 0.5 s.
merge_regions, which every extrude, revolve and surface feature runs on the
regions it builds from, now leaves out a region whose boundary repeats an
earlier one (within 1e-7 of its size; corners and segment middles on the
other loop both ways, holes alike). The selection itself keeps its
multiplicities, as profile_refs' tests require.

* claim: #6186
* Timeline: a reorder evaluates the design once, from the cache it already has (#6186)
timeline.reorder checked the move on a copy of the model, then dropped it,
so setting the reordered design evaluated the moved part of the timeline
again; reorder_many (and moving features into a group) checked on an empty
model, recomputing the whole design even for a move near the end. The
check now starts from the session's own model, and the session keeps the
model it was checked on.

Search Console lists docs.solidcraft.io/, /introduction.html (the same page) and /guide/mcp.html as duplicates without a user-selected canonical. The Pages build now adds a canonical link to every book page (index.html and introduction.html both name /), skips the redirect stubs that already have one, marks 404 and the toc frame noindex, and writes a robots.txt pointing at a generated sitemap.xml.

SolidCraft is a clean-room, open-source, pure-Rust parametric 3D CAD application:
sketches with a constraint solver, a parametric timeline of features, a B-rep
kernel, and a desktop UI that agents can drive. Projects published by
[storytold](https://github.com/storytold) can serve as references for implementation conventions.
Any code adapted from other projects (MIT OR Apache-2.0) is noted in ATTRIBUTION.md.
SolidCraft is a clean-room, pure-Rust parametric 3D CAD app (sketch solver, feature timeline, B-rep kernel, an egui UI that agents drive). This file is a router: the hard rules, then the skill to read for your task. Humans: CONTRIBUTING.md.
## Product name
SolidCraft everywhere: crates `solidcraft-*`, binaries `solidcraft` and `solidcraft-cli`,
`.solidcraft` designs, the `solidcraft/N` format tag, `SOLIDCRAFT_*` environment variables,
settings and recovery folders, the MCP server name, docs, CI and packaging. The old name
survives only in the explicit compatibility shims listed in `docs/compatibility.md`; don't add
new uses of it anywhere else. Public docs/web/Flatpak deployments use project Pages
`/solidcraft/`; do not add permanent old-name Pages aliases.
## Start here
Work: ROADMAP.md, "Where help is wanted most" in CONTRIBUTING.md, issues labelled `help wanted`, `good first issue`, `needs-triage`; architecture in `docs/architecture.md`. Act when the code, docs and rules settle a question; ask only when it changes what users see. Local `plan/` notes are optional.
## Start every session here
1. Read `plan/STATUS.md` (current milestone, next task), then the task in `plan/execution-plan.md`
and the relevant `plan/architecture.md` section.
2. Kernel and library decisions: `plan/adr/0001-geometry-kernel.md` (what we may depend on, what
is rejected for licence reasons).
3. Follow the autonomous operation protocol (`plan/execution-plan.md` §6). Don't stop to ask
unless it lists the decision as the owner's.
## Hard rules (what enforces each)
- Independent: never copy another product's code, icons, text or templates; never drive or take data from commercial CAD. `skills/solidcraft-ground-rules/SKILL.md`.
- No GPL/LGPL/AGPL code, not even reading it (OpenCASCADE, FreeCAD, SolveSpace, CadQuery, LibreCAD, QCAD): `cargo xtask licences --check`.
- Every asset is original or openly licensed with a row in ATTRIBUTION.md; read `assets/AGENTS.md` before icon work: `cargo xtask assets`, `cargo xtask icons`.
- Never crash: no unwrap/expect/panic/unsafe in non-test code (unsafe allowlist in crash-safety), errors are `Result`, input is hostile: clippy `-D warnings`, `hostile_params_never_panic`.
- Model decisions (what an operation does, which bodies it touches, which face or edge a point or name means, depths, nearness) use exact geometry; a mesh is for display, export, previews and mesh bodies (`xtask/mesh-decisions.txt` only shrinks): `cargo xtask mesh-decisions`.
- Everything is a command and programmatic calls never open dialogs: `skills/solidcraft-commands/SKILL.md`.
- One outer UI container, one camera path (`navigation::handle`), colours from theme tokens: `cargo xtask ui-containers`.
- Application code is Rust only and builds for wasm: `cargo xtask wasm`, `cargo xtask web-offline-test`.
- The product name is SolidCraft; the old name lives only in `docs/compatibility.md`.
- Sorted lists (message catalogs, `mod` lines, languages) stay sorted: `cargo xtask lists`. Never edit generated files (`docs/features.md`, `THIRD-PARTY-LICENSES.txt`) in a PR.
- A design-format change is ONE new file in `crates/doc/src/format/pending/`: `scripts/test-format-pending.sh`.
- A command has input and output schemas (will become required; `schema/unconverted.txt` only shrinks): `skills/solidcraft-commands/SKILL.md`.
- New UI strings go in `assets/locales/pending/<slug>.json`, ATTRIBUTION rows in `attribution/pending/<slug>.md`: `cargo xtask lists`.
- A changed default keeps the old behaviour behind a preference and fills the PR's `Changes a default:` line, and no second PR for an issue a lower-numbered one closes: `pr-checks.yml`.
- A regression test goes in the area's existing test file, never a per-bug file (#3226).
- Look at open PRs first, claim with a draft PR (lowest number wins), one topic per PR, never force-push `main`, no pushes just to catch up with `main`: `skills/solidcraft-contributing/SKILL.md`.
- Show observable changes with real screenshots or a recording, captured yourself.
- Run `cargo xtask ci` before every commit, without switching branches while it runs. `cargo xtask skills` keeps this file and `skills/` honest.
`plan/` is gitignored (local only).
## Never crash
People trust SolidCraft with their designs; a crash loses their work. **This outranks feature work.**
- **No panics in non-test code:** no `unwrap()`, `expect()`, `panic!`, `unreachable!`, `todo!`,
`unimplemented!`; no `unsafe` (`unsafe_code = "forbid"`). The exceptions, in the app crate and in
`crates/threedx-client` (which deny it instead), have no safe API: the macOS-only
`crates/threedx-client/src/macos.rs` (loads the 3Dconnexion driver's client framework at run time
and calls through its function pointers), two functions in
`apps/solidcraft/src/open_documents.rs` (macOS hands Finder files only to an Objective-C
method), the Windows-only `apps/solidcraft/src/native_crash.rs` (the exception filter that
records crashes inside native code such as graphics drivers), the Windows-only
`apps/solidcraft/src/native_frame.rs` (the window procedure that answers the resize-border hit
test of the window without OS decorations, and gives its class the icon the taskbar falls back
on) and the Windows-only
`apps/solidcraft/src/space_mouse/windows_hid.rs` (asks Plug and Play which HID interfaces are 3D
mice, so no other device is sent anything).
- **Errors are `Result<T, E>`** through the crate's error type and `?`. An unfinished feature
returns an error ("not supported yet: …"); it never panics.
- **Input-derived numbers are hostile** (command parameters, design files, control-channel
input): `get()` not `[i]`, finite checks, caps on sizes and loop counts.
- **Third-party kernel calls are guarded:** everything that calls `truck` goes through
`solidcraft_kernel::guard`, which turns a panic into `KernelError::Internal`.
- **Last-resort guard:** `Session::execute` runs every command under `catch_unwind`; an escaped
panic restores the design and reports `EngineError::Internal`.
- **Crash reports:** the desktop app writes every panic and every unclean exit to a local crash folder,
with the design and the commands that reproduce it (`solidcraft_engine::crash`, docs/crash-reports.md).
When someone says the app crashed, look there first: `solidcraft-cli crashes`, `crashes show <id>`,
artwork from commercial CAD products — ever.** Command icons are the original SVG masters in
`assets/icons/ui/design/svg/`, compiled through `crates/ui-egui/src/icon_svg.rs`.
**Before any icon, icon assignment or media edit, read `assets/AGENTS.md`,
`assets/icons/ui/AGENTS.md` and `assets/icons/ui/STYLE_GUIDE.md`.** Use the canonical
bases and named finished references there; never invent a parallel icon style. Any file asset must be original or openly licensed and **must have a row in ATTRIBUTION.md**
(`cargo xtask assets` enforces it). Screenshots of commercial CAD software are never committed.
Breaking this rule is the most serious mistake you can make in this repo.
- **Everything is a command.** User-visible behaviour = a command in `crates/engine/src/cmd/*`
(`CommandSpec`: id = our own dotted, lower-case id `<area>.<thing>[.<variant>]` such as
`solid.extrude` or `sketch.rectangle.two_point`, never another product's command id; label;
toolbar tab and panel; icon; shortcut; params doc; `enabled`; JSON `run`) + tests. The toolbar,
dialogs, sketch tools, palette, scripts, CLI and control channel all reach the same commands.
- **Programmatic calls never open dialogs.** `engine.execute` runs the JSON form; only toolbar
clicks (`ui.start`) start interactive tools and dialogs, which then run commands.
- **Layering** is enforced by `cargo xtask layers`: L0 `geom` → L1 `sketch`, `kernel`, `render`

| M15 | Frames and weldments (#4003): structural members along 2D and 3D sketch lines, butt and mitre corners, trim to faces and bodies, end caps, gussets, cosmetic welds and a cut list. Done: the profile library (`frame.profile.list`, `frame.profile.properties`, `frame.profile.insert`): bar, round bar, rectangular and round tube, angle, channel and I-beam, each SolidCraft's own parametric definition with exact fillet arcs and exact section properties (area, centroid, second moments), tested against hand-computed values; members (`frame.member`): one body per straight line of a 2D or 3D frame sketch, following parameter edits, with a built-in profile (its dimensions parameter expressions) or a profile sketch (its drawn material by alternating nested loops), anchor, angle and mirror; each member's name kept with its line. Left: corners, trims, end caps, gussets, welds, cut list, FRAME tab and dialogs | in progress | 60 |
M6 navigation preferences include **Touchpad**: Shift + pointer movement pans, Alt/Option +
pointer movement orbits without a mouse button, and vertical scrolling zooms. Other presets
retain their saved two-finger scroll preference; camera motion is available through
`view.navigate` and modifier-aware `ui.move` automation.
With the **Fusion** preset and two-finger pan enabled, two fingers pan and Shift + two fingers
orbit freely, with pinch zoom and mouse bindings unchanged. The shared navigation handler
applies the same gestures to model and Render views and blocks orbit on flat pages.
editable, and Automatic size returns to the face's suggestion. Cosmetic/modelled and
full/partial-length options remain available. This does not add tolerance classes or
left-hand threads.
- New Body extrusion and face-offset previews show completed intermediate geometry while a
drag continues, then catch up to the exact final value. Changes to the selected geometry,
operation or feature still discard obsolete results. Distance arrows and their value boxes
follow the current frame's input.
- Large fine modelled threads use pitch-based helix resolution and tighter faceted
reconstruction fallbacks, preserving thin crests and closed shells on large shafts.
## Physical material data
- Physical material card validation (#923/#922) provides typed SI mechanical and
thermal data, per-property sources/conditions and isotropic/orthotropic stability
checks through read-only `material.properties.validate`. It does not assign or
persist properties, provide a solver or enable rendering; see
[the contract and staged follow-ups](docs/physical-material-cards.md).
- Directional elasticity (#994) queries the validated card in material-local axes
through read-only `material.properties.directional`, with source/condition review.
It does not assign body frames, predict structural behavior or enable a solver.
## Library foundations (#785, #786, #787)
- Local scalar libraries (#846) inspect/export bounded portable catalogs and copy exact
selected appearance/material revisions into existing design definitions in one undo step.
Appearance offers local loading/search/export; physical materials use existing commands.
This slice is independent of the render stack and does not change the document format.
See [the contract and limits](docs/book/src/dev/local-libraries.md).
- Proposed phases cover offline bundled/project/user packs, physical materials and
appearances, editable wood mapping, and parameterized component/assembly families.
Stable identity/revision, copied design definitions, provenance and resource limits
apply from the first implementation. Existing material, appearance and standard-part
commands remain the application paths. See [the proposal](docs/book/src/dev/libraries.md)
for source/license review and acceptance gates. This is planning only: pack loading,
texture rendering and expanded component families are not implemented by this entry.
## Render foundation
- Original starter appearances (#1722): 34 opaque recipes through existing commands, with six explicitly unavailable glass recipes and preserved legacy looks; see [the contract](docs/render-starter-appearances.md).
- Bounded linear film accumulation (#1696) supplies caller-admitted mean/variance storage and complete-pass views; actual progressive consumers remain separate. See [the film contract](docs/render-film.md).
- Definition-local visual mapping (#1214) supplies a bounded numerical frame, physical repeat coordinates and a deterministic one-time grain-axis suggestion. It adds no saved record or texture consumer; see [the mapping contract](docs/render-visual-mapping.md).
- Explicit texture normalization (#1218) produces completed float RGBA with
role-aware linear color/data semantics, bounded matrix/TRC ICC conversion and
opt-in EXIF orientation. It retains high-precision raw samples and records lossy
gamut clipping only when explicitly requested. It is not a renderer/resource
consumer; see [the supported policy and limits](docs/render-texture-normalization.md).
- Opt-in opaque PBR (#1046) connects persisted surface parameters to the integrated
product viewport and CPU PNG, using a fixed direct-light studio. Geometry and mass
stay unchanged. HDRI, transmission and textures remain separate gates.
See [the consumer and limitations](docs/render-opaque-pbr.md).
- Combined integration is tracked in #842, with independent scalar libraries in
#863 and richer PBR/material-card transport in #1086. See [phase boundaries and validation gates](docs/render-integration.md).
Render/library consumers use the merged asynchronous picker (#1127). Material-card
UI (#1094), texture mapping and HDRI lighting remain explicit follow-ups.
- R4a adds bounded CPU product-image jobs, cancellation and atomic PNG export through
engine commands, the Render panel, CLI and persistent MCP. Immutable captures and
results stay outside persistence/undo; native workers and cooperative browser tasks
share the same work protocol. See [jobs, limits and export](docs/render-jobs.md).
- R3 adds an overlay-free product scene and the integrated Render workspace, with
runtime GPU host capabilities, per-document drafts and named camera/background
controls. Design keeps its camera and drawing policy. Raster transparency remains
approximate; PBR and environments are later slices. See
[workspace and scene contracts](docs/render-workspace.md).
- R2 adds bounded named render setups in document format 21 and the read/save
and selected occurrence frames; cancel and successful edits preserve one-step undo history.
Placed feature edits preview through the edited timeline entry, and cylindrical Emboss guides
use the sketch's actual target, author or uniquely placed third-component frame.
Revolve rotators follow the actual signed axis and support symmetric and two-sided extents;
dragging a To Object extent converts its derived value to an explicit angle. Legacy reversed-axis
symmetric geometry is preserved through format 11's explicit legacy convention. New revolves
use the sketch-normal direction for each selected profile, including To Object and curved
target trimming, independently of the selected axis sign.
- Cylindrical emboss/deboss wraps bounded orthogonal line profiles, including holes, concave
outlines and nested islands, onto complete exterior cylinders or coaxial sleeves with exact
radial walls. New features infer a unique eligible cylinder when the face field is empty;
ambiguous targets require an explicit face. Saved target
and author occurrence paths retain the chosen placements; missing/split faces refuse rather
than retarget. General free-form profiles, seams, stepped cylinders and other curved surfaces
remain unsupported. STEP round-trip and independent radial/volume checks cover this subset.
- Shell and offset faces work on bodies of planes, cylinders, cones, spheres and tori (convex or not:
filleted boxes, bosses, domes, countersinks; corners where four or more planes meet, such as a
floor falling to a drain, as long as the corner's edges are all convex or all concave); draft on convex planar bodies and on walls (planes, cylinders → cones) between caps; lofts through three or more sections are smooth (B-spline sides through every section), two
sections ruled. Circular-meridian barrels retain curved inner walls through either axial
opening (#2421). Solid lofts preserve holes through sections with matching hole counts
(#2435), including inner walls and caps with openings; a hole cannot appear or disappear
between sections, and sections with holes cannot collapse to a point.
- Sketch corner tools: fillet and all three chamfer modes pick a connected corner even when
its endpoint overlaps the fixed origin or a loose point. Ordinary drawing still snaps to
the origin; clicked UI regressions verify geometry, closed profiles and undo.
islands share the same boundaries in flat preview, DXF and unfolded solids. Detached material
pieces survive unfold/refold as one logical sheet group, including split flanged sheets.
Cut-outs made in the flat pattern cross bends at any angle or curved: their edges fold to
helices and curves on the bend, their walls square to the sheet. Free-form bases use bounded
sampling.
Parallel prismatic partial-depth cuts retain pocket side and depth through transfer and
unfold/refold, with separate pocket contours in preview and DXF. Planar Intersect preserves
exact holes and retained islands, including the union of multiple selected profiles, and
records complementary depth layers as pockets while retaining the stock gauge. Unsupported
tapered or bend-crossing machining refuses atomically instead of restoring material later.
Sketches attach to a sheet's flat faces (base and flanges, either side) by panel, in the
flat pattern's coordinates, and follow it through rebuilds and unfold/refold.
A flange on another flange's far edge (a return) follows that flange's closed end and keeps
clear of the flange beside it, and the returns of one feature are mitred toward each other
with the rule's gap where their flanges meet at a corner; returns of separate features, and
flanges on returns, are not closed toward each other.
- Rolling-ball fillet accuracy: independent offset-cylinder tee references check surface
distance, actual trimmed tessellation, supporting-cylinder contacts and tangency at two
scales. The measured trimmed-part error is below 0.0001 mm; this is an analytic geometry
check. Under-resolved fits return an error.
- Contact driving checks the trajectory between clear endpoints, including linked joints,
playback and sparse motion exports. Checks use bounded tessellation samples, not exact
continuous collision detection; local thin walls and small details remain limitations.
See [contact-set limits and recovery](docs/contact-sets.md).
## Assembly dragging
The design's first part is grounded when it is made, and a left-button drag repositions a free part (`occurrence.drag`: one undo step, exact occurrence paths including repeated jointed definitions, any floating-chain member carries the chain, grounded parts and joints hold where present, Escape cancels).
## 3D sketch bridges
3D sketch drawing snaps to points on other visible sketch planes without flattening them onto
the active plane. Bridge endpoints capture their source positions; associative endpoint links,
construction-plane selection of 3D wires and loft guide rails remain separate work.
Feature dialog header chevrons collapse and restore the form without discarding selections
or edited values, including the Appearance panel.
## Construction on 3D paths
Plane Along Path has a viewport path selector, fractional position, live preview and timeline
editing. Construction planes and points resolve drawn 3D wires without applying their sketch
plane a second time. Curved paths use sampled segments; multi-curve chains, absolute distance
and reference-object placement remain separate work, as do loft rails and centerlines.
## Design properties (#1015)
- Designs carry project, part number, revision, author, organization, description and licence
in an optional `metadata` object (File → Design Properties…, `document.metadata.*`,
`inspect_design`). STEP and IGES headers and 3MF model metadata take the fields their format
has a place for. Other tools keep their own data under a reverse-DNS key, kept as it is
through open, edit and save and never exported. See [design properties](docs/book/src/guide/files.md#design-properties).
Per-component properties (a part number per component) can follow with the same type.
## Document-opening performance
- Desktop STEP import prepares consecutive independent solids in bounded batches with up
to eight workers, retaining serial traversal, result order and persistent source identities.
The web path remains serial. Original multi-solid fixtures show 64–81% lower complete
import times; single-solid assembly parts are not scheduled across nodes. See
[measurements and limits](docs/perf.md#parallel-step-body-preparation-2026-10-12).
- Design containers (#303, phase one) separate and deduplicate STEP, raw images and
lossless binary mesh arrays while keeping plain JSON as a supported Save As/export
format. Generated-mesh storage measurements reduce serialization and decoding work;
a seekable reader defers original blobs until after provisional display.
See [container format](docs/design-container.md) and [performance measurements](docs/perf.md).
- Warm saves with explicit `cache: true` can include a versioned native B-rep cache through SolidCraft-owned topology
and geometry records, with a separate truck adapter and bounded binary reader. Exact
face-source certificates and operation history survive codec round trips. A provisional
picture can be generated before original blobs are read; editing and measurement wait
for authoritative reconstruction. Cached metadata binds preview and reconstruction to
the same document despite concurrent file writes. Default saves omit this cache and never force cold
evaluation or meshing; explicit `preview: true` remains a separate warm-mesh option.
Keys, resource budgets and document/revision guards reject incompatible, hostile or
stale results. A second modelling kernel still requires its own tested adapter.
- Warm saves with explicit `cache: true` can also carry a bounded PNG thumbnail from already cached meshes.
Home reads it without rebuilding the design when its local picture is missing;
mismatched or malformed thumbnails fall back to normal generation. The image is
kernel-independent and saving never forces cold meshing to produce it.
- Parameters with units and expressions, and configurations.
- Faces and edges keep their names through edits, so references survive changes.
- Components, assemblies, joints, motion studies and exploded views.
- Sheet metal with flat patterns and DXF export, and a plastic-enclosure subset.
- A Render workspace with GPU rendering, studio lighting, materials and image export
(first release in 0.22.0).
- Import and export of STEP, IGES, 3MF, STL, OBJ and DXF, and FreeCAD and Rhino files.
- Autosave and crash recovery, and the browser build of the same app.
The full list of commands is in [docs/features.md](docs/features.md). Release notes for each
version are on the [releases page](https://github.com/tangency-labs/solidcraft/releases).
## In progress now
Each feature below is a [milestone](https://github.com/tangency-labs/solidcraft/milestones) holding
the issues for it, so the count shows how far along it is. Counts are as of 2026-10-25, one per
feature or request. Work merged on a feature branch (`drawings`, `render`) counts as built but
reaches the app only when that branch merges. They are rough, not a promise.
- **[Rendering & materials](https://github.com/tangency-labs/solidcraft/milestone/17)**: in progress, 9 of 34 pieces done, 3 of them built only on the `render` branch and in the app when it merges. The basic Render workspace is already in releases (0.22.0); the interface rework (#6281) and the material and light libraries are what is left.
- **[Drawings](https://github.com/tangency-labs/solidcraft/milestone/8)**: in progress, 3 of 21 pieces built (2 in releases, 1 on the `drawings` branch), and 3 more partly built there (sheets and borders, bill-of-materials types, the paper scene). Not in the app yet: it lands when the `drawings` branch merges. Today you can export the current view as a DXF.
- **[Sheet metal](https://github.com/tangency-labs/solidcraft/milestone/15)**: in progress, 1 of 30 requests done. Flanges, hems, unfold and flat patterns already work; the 30 are extensions, mostly the per-edge flange options (segments, miters, partial flanges, reliefs) and bend allowance.
- **[Sketching](https://github.com/tangency-labs/solidcraft/milestone/14)**: in progress, 12 of 50 pieces done. Dimension types, selection and snapping options.
- **[Solid modeling](https://github.com/tangency-labs/solidcraft/milestone/2)**: in progress, 9 of 50 pieces done. Blends, holes, threads and patterns.
- **[Assemblies & joints](https://github.com/tangency-labs/solidcraft/milestone/3)**: in progress, 4 of 19 pieces done. Joints, motion studies and exploded views already work; placement rules, linked sub-assemblies, fastener stacks and weldment corners are the pieces left.
- **[Import & export](https://github.com/tangency-labs/solidcraft/milestone/5)**: in progress, 7 of 39 pieces done. FreeCAD, SolidWorks and point-cloud import, and mesh export options.
- **[AI agents & MCP](https://github.com/tangency-labs/solidcraft/milestone/18)**: in progress, 2 of 8 pieces done. Agent chat and the MCP server.
- **[Interface, web app & plugins](https://github.com/tangency-labs/solidcraft/milestone/4)**: in progress, 31 of 96 pieces done. Ribbon redesign, navigation, themes, the web app and plugins.
- **[SMLib kernel migration](https://github.com/tangency-labs/solidcraft/milestone/1)**: in progress, 1 tracking issue open. The kernel is moving from truck to NVIDIA's SMLib (usd-brep, Apache-2.0) on the `kernel-smlib` branch; it is not in releases yet. Tracked in [#4012](https://github.com/tangency-labs/solidcraft/issues/4012).
## Next
- **[Surfacing](https://github.com/tangency-labs/solidcraft/milestone/16)**: next, 6 of 14 pieces done. Patch, trim, blend and match exist; the rest of the surface toolset is planned.
- **[Manufacturing / CAM](https://github.com/tangency-labs/solidcraft/milestone/9)**: next, 1 pieces tracked, none done. There is no CAM in SolidCraft yet. Send to Slicer and a first toolpath slice are in review; proposals are [#1153](https://github.com/tangency-labs/solidcraft/issues/1153) and [#1621](https://github.com/tangency-labs/solidcraft/issues/1621).
Features are not tied to a release or a date. Work lands in the daily releases as it is finished.
Anything without a milestone, such as bug fixes, is not a feature and is not listed here.
## How releases work
- Releases ship daily, as numbered versions (v0.22.0, v0.22.1) with nightly pre-releases in
between. They are delivered through the in-app updater.
- SolidCraft tells you when a newer stable release exists and never updates without asking.
Where it can replace itself safely (AppImage, Windows installer and portable builds) there is
an **Update now** button; downloads are checked against the release's SHA-256 list. See
[updates and privacy](docs/book/src/guide/updates.md).
- Design files carry a format number. A new version opens designs from older versions, but an
older version refuses a design saved by a newer one (0.22.0 writes format 35, and 0.21.0 and
earlier will not open it). Each release's notes say when the format changed. Keep a copy of
an important design before you move to a new version.
