The set-back corner's hole is filled with one four-sided patch per corner of
the hole meeting at a centre point (solidcraft_geom::fill_quad), each holding
its two half-sides exactly (rational rows for the rounds' sections, standard
form, rational-line pcurves), G2 to its neighbours and to the next patch
across its spoke; the height-field fill (fill_matched) is removed. The kernel
grades a corner's seams as the ladder does (corner_continuity), and the ladder
uses it. Ladder 07/015 and 07/019: 15 and 18 faces.
Known: the eight-corner box test is ignored: at some corners SMLib gives one
half of a section as a polynomial spline 1.7e-5 mm off its round, tangent out
of its plane, which the patches cannot meet within tolerance.

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
keep the drill they stored either way.

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;
1/2 NPT: 17.473 mm, drilled 11/16 in (17.4625 mm).

A preset's thread options save `modeled` and `ease_out` (a named ISO 3508 runout or the fade's
length, kept portable as the other lengths are) and recall them into the dialog. A runout
without a modelled thread is no preset's. Recalling checked the thread with the metric parser
only, so a UNC, G, Rp, Rc or NPT preset was refused; it checks the tapped-thread catalogue now.

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
4753 hint come from the catalog entries already on develop.

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`
drops a saved `ease_in` as the design opens. The runout test covers the short, standard and a
sub-turn fade at the inner end.

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
change file; `pending/thread-ends.rs` records them and rewrites a saved `tip: chamfer` to
`both`.

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.

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

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).

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

The M10 thread's 32 flank-piece joins meet with normals about 1.5e-6
degrees apart (measured independently with seam_diagnostics); each is
left out of the shaded view, stays pickable and stays in the wireframe.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.

Main's Arabic and Hebrew catalogs (#3768) arrived with thread.direction, thread.left_hand and
thread.right_hand, the labels of #4414's screw direction, which this branch replaced with the

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
the Rust caches the PRs into it restore.

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.

Every job that builds the kernel with SMLib runs scripts/fetch-smlib.sh after the toolchain:
the host's prebuilt archive, the matrix target's for cross builds, wasm32's for the web jobs.

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.

On the web target the smlib build compiles SMLib for wasm32-wasip1 with wasi-sdk's clang
(WASI_SDK_PATH), with wasm exceptions in the exnref encoding that wasi-sdk's libc++ and Rust
use, and links wasi-sdk's libc++, libc++abi, libunwind and libc. The WASI calls libc makes are
defined in ffi.rs: stdout and stderr go to the log, the clocks are the page's (the C API times
every call), and there is no file system or environment. solidcraft-web gets an smlib
feature, off until CI has wasi-sdk.

Code main added since the last rebase reads the placed model, a camera or a scene
as values; on this branch they return Result. Picks and the edit dialogs read the
session's placed model through open_meshing::session_world, as the others do; the

computed edit pass the error on; tests unwrap. A test meshing bodies uses

A modelled thread never changes the size of the shaft it is on (#1018, #2853): a
shaft thicker than the thread is refused with the size to make it, as
tests/kernel-cases/threads/2705 expects ("this 14.6 mm shaft is too thick for a
modelled M14 thread; make the shaft 14 mm for M14"). This takes out the turn-down
of #4256: `thread_turn`, the fit that let a thicker shaft through, and its tests;
the 9 mm shaft refusing an M8 and the preview's M6 refusal on an 8 mm shaft are

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).
cases.py now writes 013 (the corner setback, graded by its convexity bounds)

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

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°

pitches along), in one boolean with their union. A designation that gives the lead

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%.

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

A cone face bounded by its base circle and its seam out to the apex and back
turns once round the axis and closes at the apex. add_seams counted the turn
as a loop without a seam and added another, out and back from the same

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
1.9e-4 off the bore (SmBrep #4, SmEdge #13). Each sample higher or lower

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

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);

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.

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.

apart (twice), two cubes for interference, a ring with a cylinder, the
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.

A feature's touching parameter says what a join makes of solids that
share no volume and no area: separate (the default) splits the joined
body's pieces that share no face into bodies of their own, named, with
history and lineage, as a cut's pieces are; one_body keeps one body of
several pieces. The state records how the kept-apart pieces met
(KeptSeparate: along an edge, at a point, apart) for the feature's
notice.
Older builds kept every join's pieces in one body: the pending format
change join-touching-bodies gives each joining feature of an older design
touching: one_body, so existing designs keep their bodies.
kernel-cases 2896-join-arm-end-near-ring-wall-gap: the arm meets nothing,
so it now stays a body of its own (body_count 2, one shell each).
kernel-cases that join solids apart to make the body they test ask for
it with touching: one_body: 3379 (the hub joined to the ring before the
spokes reach it), 3455 (64 pegs in one body) and 3526 (a two-lump target
for an intersect).

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
or STEP B-spline writes it) is that plane at every parameter, so its pcurves
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

none of its uses brings a pcurve to (over its boundary's extent on its label), and every edge
whose uses bring none and whose faces are planes, splines or on forms (a circle about such a

- A meridian of a sphere or a tube circle of a torus (a circle in a plane through the axis) has
its exact pcurve on the label: u fixed at the arc's azimuth, v its angle from the outward
radial, alpha + s t.
- 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
parameter at a pole bounds nothing; a boundary that never goes round covers the turn), what its
form is built over with no pcurve involved.
- A face that goes all the way round gets a form of exactly one turn, closed and so periodic.
- `along` projects inside the face's box (a spline extended past its knots, or a profile turned
past the face, has other preimages), and takes a closed form within the record's tolerance, as

`On::fit` and everything it used (samples, least squares, breaks, filled poles) are deleted, and
the STEP reader no longer retries a face at ten times its tolerance. A pcurve is exact (closed
form, an affine image, or a straight line along a form's parameters) or the face is refused:

The rig and ladder are as with the fit (333/372, 101/116; none lost; 3806, already failing, now

`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
gives its 3D curve as degree-7 Hermite pieces of the fold, within 1e-7 mm. Its pcurve on the
bend is now built the same way, on the edge's own parameter: degree-7 Hermite pieces matching
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 edge within 1e-7 of its size. An approximation by construction from exact derivatives, like
the edge; nothing is fitted. B-spline and NURBS edges alike (a NURBS's derivatives from its
homogeneous form). Breaks within rounding of each other are one.

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

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.

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

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

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
semi-angle threshold.

The angles a cylindrical wall spans came from its arc's two ends about its middle; a wall in
one piece has a whole circle for an edge, whose ends are one point. The circle's parameter is
its angle, so the span is the edge's interval about the angle of its middle: half the turn
either side for a whole wall, as for any arc.

A rim's arc was its two ends and the point halfway, its circle found through the three: a
whole circle, one closed edge now, has one end and no circle through it. Each arc piece carries
its circle's centre and the angle it turns about the face's normal, read off the record circle
(its parameter is the angle), and offsets, profiles, edges and walls are made from those; the
loops' turning is read through points a third and two thirds along each arc. assemble's
unused edge_point goes.

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.
Cases, singly on 9f5ad20c: fillets/1191, 2797, 3753 and sweeps/1269, 2295 fail before and pass

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
(a hang in rig-1) passes.

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`.

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.

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

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

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.

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

write::topology::layout says which shells make each solid (a material region's outer shell
and its voids) and which are sheets, and outer_loop which loop of a face is its outer one;
the STEP writer uses both, and the IGES writer can too.

Import: every solid is read by solidcraft_step::topology into its record and taken into
SMLib as given (step_in/parallel.rs smlib_part), the one path; the truck readers
(step_in/brep.rs, split.rs, geom.rs) are deleted. Placements are column-major 4x4 matrices
from solidcraft_step::read placements; an instance is its part's record moved there
(ops::transform_matrix), or the very part at the identity. Assemblies, names, colours,
shared displays and the public API are unchanged. step_orientation_errors lists the faces
the STEP reader turns over (their loops disagree with their same_sense).
Export: each body's record is written by solidcraft_step::write::topology as the exact
B-rep (solids per material region, open shells as a surface model, the record's pcurves);
step_out writes products, units, colours and assemblies around it with Writer. The truck
writer and every post-processing pass (split-face merging, sheet trimming, analytic
recognition, short-edge collapse, the re-read fallback) are deleted. The context's
uncertainty is the loosest record tolerance exported.
Tests: ported to the record API with their assertions. Deleted, as tests of deleted
internals: conic_tests extruded_ellipse_seam_uses_profile_angles_for_oblique_sweeps and
conic_arcs_are_exact (truck geometry reader), tests offset_surface_analytic_geometry_and_
orientation, offset_surfaces_nested_and_hostile and periodic_knot_bsplines_are_read_on_
their_domain (truck geometry reader), corpus_truck_and_schema_4_counts (truck comparison);
the orientation counter asserts (crate::body::ORIENTED, gone with orienting by mesh).

A placed revolution is written exactly whenever its placement maps revolutions about the
axis onto revolutions (one scale across the axis, another along it, then a rotation or
reflection), its profile placed with it; a conic profile stays a conic under a similarity.
A void's CLOSED_SHELL keeps the record's sides (normals out of the material, into the void)
through an ORIENTED_CLOSED_SHELL .T., as SolidCraft has written voids. Reader::frame reads an
assembly placement (AXIS2_PLACEMENT_3D, or _2D in the XY plane).

faces as ADVANCED_FACEs on their exact surface with FACE_OUTER_BOUND/FACE_BOUND of
EDGE_LOOPs and VERTEX_LOOPs, edges as EDGE_CURVEs on their exact curve over the record's
interval, and the record's exact pcurves as PCURVEs of SURFACE_CURVE/SEAM_CURVE. A record
surface's (u, v) map linearly onto STEP's (planes on their orthonormal frame, narrowing
cones turned over, revolutions angle first), and pcurves go through the same map.
Writer::add_distinct writes topology entities unshared. topology::Solid lists the faces
the reader turned over (their loops disagree with their same_sense).

surface's own row at the point's other parameter (each control point its

then bisected on the pcurve), the pieces between kept where their middle lies
inside the face (even-odd over the loops), neighbouring inside pieces joined.

Rulings that are constant, or keep their angle to an arc's axis, move the edge by
an affine map: the far edge is the edge's exact image and the strip exact. Any
other ruling field (a normal turning along a free-form face, a tangent carried
round a free-form curve) ends on an offset curve, which has no exact NURBS form
in general: SMLib holds one only implicitly (SmOffsetCurve) or approximates it
(NL_CrvOffset.h, N_CrvOffsetApprox), and its ruled surface (SmApiCreateRuledSurface)
takes two B-spline curves it is given. Such a strip was a B-spline fitted within
1e-3; it is now refused by name. The fitted-strip test checks the refusal.
The round-corner cases count one face per corner: SMLib's revolve makes a quarter
turn one face, where truck's cone builder made two (12 faces and joins, now 8).

SMLib is the only kernel now. cargo xtask kernel-cases ran every case once
per kernel asked for (--kernel default|smlib|both), setting
SOLIDCRAFT_KERNEL per run, and wrote a column per kernel; solidcraft-cli no

The rig and the ladder run each case once, through solidcraft-cli built with
--features smlib (cargo run passes it), and report one result per case:
--kernel and the env var are gone. Each run has an output folder (--out,
default target/kernel-cases, target/kernel-ladder for the ladder) holding
results.json (every case's full result, which --results used to write on
request) and dumps/<area>-<case>/: every case runs with
solidcraft-cli kernel-cases --dumps=<out>/dumps, so a failed SMLib call
leaves its inputs for replay.
The ladder's golden holds one entry per case: golden.json is the last
recording's smlib entries, which predate SMLib running every case (its
reason says so); record it again after the first SMLib-only run.

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.

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

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};`.

solidcraft_smlib::set_dump_dir. `solidcraft-cli kernel-cases --dumps=DIR` now points SMLib's
dump folder at DIR/<area>-<case> before each case runs, so a failing call leaves its

turns it off after the run. Off without the flag. The kernel exposes it as

ssi::intersect took a sample count and gave each intersection curve as
samples: its 3D points, its UV points on each surface and the surfaces at
them. The fork's 947eedc hands out the curves SMLib's intersectors return,
exactly (smlib_ssi_curve_nurbs: degree, knots, control points, weights), and
drops the samples; SMLIB_ABI_VERSION 4.
SsiCurve now holds the 3D curve as a schema 4 Curve::Spline or
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
unit test plane_through_sphere_is_a_circle evaluates the exact curve.
Nothing else used the samples. SMLIB_REV: the fork at 947eedc.

Copy, unstitch, reverse and remove faces, Patch (a sketch region, or a planar loop
of a body's edges) and Extend work on the body's record: Parts puts any faces,
edges and vertices into canonical order, and each face taken is the body's face
(Kept), its edges the body's. Sheets are SMLib's sweeps with no caps (extrude,
revolve, curve sweep, stations for twist/scale/orientation/rails), a chain at a
time; a loft lofts each column of matched segments and stitches the columns.
History: a wall comes from the segments its edges in the start plane lie along.
Stitch joins the bodies' records and sews them with smlib_stitch, faces and edges
carried back to the bodies through SMLib's tags. Offset Surface offsets each face

loft_rails.rs placed stations between truck wires. Its law now works on the

Case 4056 (a keel rail lying in the bow's sketch plane): rail() anchored every
section at the rail's first crossing of the section's plane after the section
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
last, so the last section is met where the rail ends; the sections between are
met at their first crossing, as before.

planar_sources reads each face's oriented plane from the body's record

truck faces; the lineage rules are unchanged. planar_regularize picks the edges

source unless generated walls, off every split line) from the record's edge
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
surfaces by knot removal and sampling.
The planar_sources tests read face points, edges and planes from the record;

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

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

Encoding writes the body's own record and decoding makes the body from it: the adapter to and
from the old kernel is gone. A record goes into SMLib as given (SMLib's own form); one SMLib
refuses is an error that names why, never sent through SMLib's healer. A body made by SMLib keeps
the SMLib body. The bounded preview of a decoded body is a coarse mesh from the planner, charged
to its triangle budget.

A boolean is SMLib's boolean, its history SMLib's tags: the jittered retries, tool nudges, prism
and coaxial routes, the retry result guard and their diagnostics are gone. A rigid placement moves
the record; any other matrix goes through SMLib's transform (new Brep::transformed over
smlib_brep_transform). Bodies apart join as their records side by side (brep part::compound),
with each piece's faces, sources and history; apart means their exact boxes do not meet. A split
is the intersection with a half-space box, with no faces pushed off the plane.

What stays is the composition of a multi-step operation's histories (composed, placed, kept,

Deleted with the old kernel: heal_build, truck_result, heal_body and heal_prism_result (heal

The SMLib point sweep refused a polyline whose points turn gently (a smooth run

the path its points make, and SMLib's cornered sweep mitres it at each point.
Curves with an exact form no longer reach the kernel as points (previous
commit); what still does (curves projected onto a face, intersection and iso
curves, sweep_path's point lists) is followed as those points.

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
space of degree 1 to 9 (homogeneous control points), so a drawn spline's cubic
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
curves in a point path; PathSeg gains reversed, mapped (a placement) and
of_sketch (a sketch segment on its plane). The cubic_* helpers are deleted.

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
strip along its axis, around and both (now an extruded arc, not a truck
revolution), the extruded strip, the parabola extended naturally (now a
conic extruded), back to bounds (the saddle from loft_sheet and trim),
hostile requests. Deleted, as what they test no longer exists:
neighbours_lengthened_or_square, self_intersecting_extensions_are_refused,
a_disc_grows_by_its_curved_edges, neighbouring_faces_extend_together, the
tangent/curvature run-off half of the B-spline test, and

untrim keeps its signature and messages. The face is picked in SMLib by a
point inside it (the centre of its largest mesh triangle), holes by their
points; SMLib deletes the holes or rebuilds the face over its surface's
parameter box with the holes kept (fork c6c7fb4). The body goes tagged as
operand 0, so faces and edges come back with their origins; the untrimmed
face is Modified. A face whose span goes all the way round its surface now
closes on the seam instead of being refused.

loft_sheet and trim instead of truck types; the torus face copied out by a

A solid body holds its record (canonical faces, edges and vertices are the body's everywhere) and
builds its SMLib body from it on first use, or keeps the one the operation made. Queries read the
record: planar faces, outline and exact bounds, counts, closed shells, lumps from its material
regions (record parts, with their history), shell nesting from its regions. The orientation mesh,
the revolved-face rephasing, kept tolerances and the old kernel's mesh caches are gone. History's
edge faces come from the record's edge uses. The kernel no longer depends on the old kernel's
crates; SMLib's crate is a plain dependency (without the smlib feature it answers not built).

patch_loop picks the closed loop among the record's edges, certifies a plane (lines by
their ends, splines by their control points, conics by centre and tilt, traced curves by
a planar support) or fits the height field, and assembles one face on the body's own edge
records; the height field's parameters are plane coordinates, so each line or spline
edge's pcurve is its exact projection (segmented to the edge's interval). The history
marks the face generated and each edge the body's own. A fit on circular, elliptic or
traced edges, whose pcurves on the spline have no exact form, is refused by name, as is
the general fill (G1/G2, points, loops bounding no height field) until it is ported.

The faces' descriptions become a record with exactly the topology they give: vertices

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
winding number about it is one), orders everything canonically and validates it.
SMLib imports the record as trusted; the body and the face each body face came from

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

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.
Brep::mass_properties keeps MEASURE_ACCURACY (1e-8) as its tests' default.
SMLIB_REV: the fork at dcbb07d.

A rotation and a translation move every point, axis and control point and leave parameters,
pcurves, tolerances, orientation and the canonical order as they are: the same B-rep in other
coordinates. Placing a body (assembly instances, patterns) no longer needs a kernel round trip.
Reflections and scalings change parameters or geometry kinds and go to the kernel.

A join is hidden when both faces are clamped Bezier B-spline surfaces swept by one
linear translation (read from the record's spline net, the face's side from its shell)
and the edge is a straight line on a ruling of both, their normals agreeing within the
certified angle, as before. The edges are the record's, in the order the mesh has them.
Tests take the record (a closed edge's equal end vertices, the ruled face by its spline
net, ruled() on record control nets); the case that bowed a truck edge in place is
removed (a record edge cannot be changed under a body).

blend_vertex.rs (a sphere at three rounded edges) built blends on truck; SMLib's blend

fillet and chamfer through the public functions only, so it stays, mounted from blend.rs.
curveblend_tests.rs and curveblend_law_tests.rs go with the builder: they test its

SMLib's constant-chord round (smlib_blend, SMLIB_BLEND_CHORD). On a straight edge
between planar faces a radius law whose band runs past the faces at any of 256 stations
is refused as too large before SMLib runs, as before. The edge setup, the band check and
the taper's room read the body's schema 4 record: planar faces' outward normals, the
directions into them, side edges' exact tangents at the ends; a curved boundary is
divided to within the clearance for the containment test. RadiusSpline evaluates with
the geometry crate's B-spline basis.
The truck variable-radius surface builder and the rolling-ball law and chord blends are

fillet, fillet_each, fillet_g2, chamfer and chamfer_sides blend every picked edge in one
SMLib call (smlib_blend / smlib_chamfer_sides), which builds the rounds, their tangent
chains and the corners where they meet. The #1080 fit check (blend_fit) reads the body's
schema 4 record: planar faces' outward normals, the direction into a face across a
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
and the doc's reduce path rely on that), and the volume and wrong-way checks after it.
fillet_max_each groups the edges by their faces and ends in the record. fillet_g2_corners
is refused: SMLib's corners are a sphere or a Coons patch, not G2.
The local truck blends, their reorder search and every truck helper they used are gone.
Tests: blend.rs's tests call fillet/chamfer instead of the deleted internal `blend`; the
assertions on the deleted quintic construction's surface and curve parameters and on

radii the two walls cross along two ellipses that meet at the two points
where the walls are tangent (x = 25 and 35, y = 20, z = 10), so each wall is
left in two pieces that touch only at those points, with no edge between
them: separate faces, 10 in all. SMLib makes those 10 (volume exact); truck's

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
shown_scope in extrude); this one, which also covers Join and keeps the shown
bodies as participants, replaces it. Its test stays.

A closed path was always followed from the start of its first picked curve,
wherever the profile stood on it. A profile drawn at the middle of a line was
then carried round the path standing off it by the distance between the two
(walls offset, the rounds turned the wrong way, on both kernels). Now the
closed chain begins where the profile's plane crosses it nearest the profile,
the curve there split in two (or at the joint there); open paths and paths
that already start on the profile's plane are unchanged.
Test: a 4 x 3 profile at the middle of the bottom line of a rounded rectangle
swept round it: Pappus volume and the tube within 2 mm of the path.

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

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

sorted all of them by distance. The grid is the same for every point of a

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

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

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.
(not built: base in progress) tess/ has no errors under cargo check; the rest of the crate is
the no-truck branch's.

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.
Cases now passing on SMLib: booleans/3633, sweeps/1184, 2435, 3111, 3006,
3505, 561, 96, ladder 04/003 and 004.

The fork's new smlib_loft_to_point (a pyramid from a planar section of lines
to an apex) as Brep::loft_to_point. The pin brings the sweeps' other
changes: a loft's section may hold holes (loops lofted loop to loop), a
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.

Two SMLib fixes (tangency-labs/smlib r-shell-fillet):
- b0e84f4: faces an extended offset already mated are not intersected
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
with a nudged pleated loft, valid again; booleans/2801 passes too).

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).

SMLIB_REV moves from 276b509 to capi-solidcraft 2d7c7ed: a fillet crash at an
unsupported corner (#453), rounds ending on a tangent seam (#418), radius laws
with a corner (#430) or that cannot be evaluated (#458), a round over a hole
(#422), a sphere's own patches kept apart (#423), offset surfaces extended the
same way whatever was evaluated first (#419), swept walls sharing their planes
(#434), the internal thread's last vertex gap (#410), shells across rounds
thinner than the wall (#397), nested shells imported in any order (#388) and
the tessellator held to its chord tolerance (#390).
Three tests follow: a radius law with a corner is now built, so the SMLib
tests check its volume (8000 - (1 - pi/4) 20 28/3) and that a law pinching to
zero inside the edge is refused; the split coil's halves now measure within
1e-5 of the closed form, so they are held to it rather than to the whole
coil's mesh, which is only within 3e-3.

The kernel accepts `truck` (as well as unset) for its truck backend, and
`boolean_kernel()` reports that backend as `default`. The rig compared
the raw setting with that name, so a run with SOLIDCRAFT_KERNEL=truck

not truck" instead of grading it. The rig now names unset, empty 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
instead of SMLib's 46424.50 (tangency-labs/solidcore#433, kernel case
sweeps/3528-revolved-dome-cut-by-a-ball-on-its-seam). Every other loop is

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.

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,

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

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).

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.

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.

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

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

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).

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
of the record's faces, in the record's face order, so a body made from the
record (in another kernel) can trace its faces to the file, as the truck
import's face_origin does.

Imprint cuts each face of a body where a tool body meets it (the fork's

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).
Tests: per-edge rounds and chamfers and the chord round against analytic volumes, the linear law
from either end, and refused laws and picks.

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
refuses a thread off its hole's or shaft's size is the engine's sugar
(AGENTS.md). So the seven cases (995, 1443, 2152, 2969, 3366, 2369,

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
neither kernel fits a thread to a face that is too large or too small.

With SOLIDCRAFT_KERNEL=smlib, extrude (and extrude_whole_sides, so boxes and cylinders too),
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.

Brep::extrude (straight or drafted), Brep::revolve, Brep::sweep (turning with the path or only
moving along it), Brep::loft and Brep::screw_sweep wrap the fork's new smlib_sweeps.cpp shims.
Profiles, paths and sections are lists of sweeps::Curve (lines, circular arcs, NURBS), turned

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.

inward wall that leaves no room inside the body with its own status, Error::NoRoom, instead of
an argument error, so callers can say what is wrong; the test that a wall thicker than the box

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

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

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.

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.

SMLIB_REV moves to tangency-labs/smlib capi-solidcraft 1499681, eight SMLib
commits for surface/surface intersection: an empty curve is no longer
reverse-traced (SM_ERR_NULL_POINTER), tangent curves are traced once, curves
split at singular crossings, interior tangential contact points, tangential
curves and branches through tangent nodes, small loops above tolerance, and
high-order contact curves covered across their band. The corpus test's pass
list grows from 81 to 111 cases; the 8 still failing are all below SMLib's
1e-5 zone tolerance (angles 1e-6..1e-8, offsets 1e-7, loops of 2e-6 or less).

With the native feature, smlib_global_intersect_at_1e_6 builds both
surfaces of every case through solidcraft_smlib::ssi, intersects them
at approximation tolerance 1e-6 with the corpus runner's 4001 samples
per curve, turns the answer into what the runner writes for gsi, and
scores it. It asserts the exact set of passing cases (81, as score.py
grades the runner: 81 PASS, 25 INCOMPLETE, 11 WRONG TOPOLOGY, 2 ERROR),
so a regression and an improvement both fail until the list changes.

ssi_score::score_case grades an engine result (sampled curves with xyz,
uv1, uv2, both surfaces at the UV samples and the curve type; points;
status; or a crash) against a corpus case: CRASH, ERROR, INCOMPLETE,

ssi_corpus.rs checks every case parses, every NURBS surface lies on its
truth, the truth itself passes (bar unsplit singular points), and the
verdict rules. The ignored parity test scores the corpus runner's raw
outputs and compares with score.py: 119/119 identical verdicts and
flags for SMLib GlobalSurfaceIntersect at 1e-6 (81 PASS).

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.

784, 1753 and the two 1666 lofts came from holes in exported meshes, so

Two faults made simple curved solids look open (#818's blind hole: 80 open edges, a stadium
slot: 52):
- It meshed with `refine`, the measuring mesh, which splits triangles across curved faces on
their own and leaves T-junctions on the edges they share with neighbours. It now checks the
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.

- `"watertight": true` meshes each body (chord tolerance `tolerance.mesh_mm`, default 0.01 mm)

Reverts 1375e905. A modelled thread fits by default: a hole too wide for it
is filled to the tap drill, a shaft too thick is turned down to the major

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.

`"outcome": "solid_or_refused"` takes a clean refusal, or else grades the result as usual. Two
bodies that touch along a circle only (#168, #3841) have no one-solid union: a refusal or the two

(two bodies, a refusal) and now agree.

- `"shells": N` in expected.json grades the total number of shells: a body with a sealed void
holds two, and some joins keep several lumps in one body. Those cases (#3175, #3455, #3526,

- When SMLib's record conversion says "not supported yet" (revolved surfaces, traced intersection
curves), its check gives no verdict. That's shown but not graded, since it isn't a fault of the
body. solidcraft_kernel::SmlibCheck carries the three outcomes.
- `$OUT` in a recipe is a scratch directory outside the repository, for files a case writes. The
two STEP-export crash cases write there instead of /tmp.

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.

The smlib_booleans example answered "not supported yet" for every SMLib case.
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
tags, and measures its volume with mass_properties at MEASURE_ACCURACY, so 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.

Brep::boolean (union, subtract, intersect; Ok(None) for an empty result), Brep::solid_count,
Brep::fillet, Brep::chamfer and Brep::shell, over the fork's smlib_ops.cpp shims (ffi/ops.rs).
Edges and faces are chosen by points, each the nearest within a tolerance; a point that
selects nothing or cannot decide is Error::NoMatch / Error::Ambiguous with its index, and a
solid input that gives anything but a closed solid is Error::NotSolid. Fillets and chamfers
take whole tangent chains; a chamfer distance is the setback along each face; a shell's
thickness is negative inward.
The C API with these shims is version 2 (the fork's capi-flat line), so ABI_VERSION is 2.

SURFACE_OF_REVOLUTION reads as a placed revolution (u the angle, v the profile's parameter,
STEP's normal); SURFACE_OF_LINEAR_EXTRUSION as an exact spline surface, the profile as a
(rational) B-spline times degree 1 along the vector; a circle extruded along its axis or
revolved in a plane through the axis as the cylinder or ring torus it is. Line, conic and
open-conic profiles are bounded by the face (a closed conic's seam outside it, a revolved
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

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

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-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.

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

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.

SMLib runs in a child process per case, so a crash inside it is reported as

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

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.

ffi::line was a safe public function reading any raw pointer. The log
callback now lives in ffi.rs, reads the C string there, and hands the
crate a String through a safe sink, so no safe function takes a pointer.

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
them as they are (r(v) = r0 + v tan a already covers them), with the
natural v range below the apex. The check that no region lists a shell
twice was quadratic per region (about 1e9 comparisons at the caps); it now
remembers the last region that listed each shell.

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
and its tessellation is unchanged.

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
about 20 s on 14 cores (designs run side by side).

The corpus naming test (next commit) records what every stored face and
edge name resolves to, and must find it exactly as a rebuild does. Three
lookups were crate-private: `locate_face_on_body` (a feature's face
points, tried on the body the feature names first), `blend_target` (the
body a fillet or chamfer rounds) and `Document::anchored_face_indices`
(the faces a face-attached sketch is on). Visibility only; no behaviour
changes.

docs/native-brep.md describes schema 4: the records with their SMLib and
STEP names, regions and shells, the loop convention, every edge's uses,
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
fails by 30 mm.

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
unchanged (fields, serde derives) to solidcraft-geom, so a backend can
report history without depending on solidcraft-kernel. The pure methods
(composition, renumbering, count checks, mark_shared_split) move with
them and return brep::history::Failed, which converts to
KernelError::Failed with the same "history: …" message.
What needs a kernel body (History::identity, check, face_sources) stays
in the kernel as the BodyHistory trait; solidcraft_kernel::history
re-exports the types, so existing paths keep working.

A band of a cylinder bounded by two full circles and no seam cannot close
in (u, v): each loop's pcurve runs one period. The test records that such
loops come back continuous and a period open (the caller needs a seam
there), and that a hostile tolerance is refused.

Each sample of an intersection curve is one of truck's double projections
(about 0.13 ms in a release build), and a fit evaluates the curve at every
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 (release), from 183 and 638 ms.

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.
