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.

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

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

* geom: ring_edges for the edges of a closed ring
Every walk over a polygon's edges, the last back to the first, spelled
x.iter().zip(x.iter().cycle().skip(1)); eighteen of them now call
geom::ring_edges. Three redundant take(len) calls go with them.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* geom: Ring, a closed ring that knows it is closed
A Ring holds items in order around a closed polygon, loop or fan; edges()
walks each with the next and the last with the first, corners() each
with both neighbours. Ring<Vec2> has signed_area and even-odd contains.
Loop2::polyline returns a Ring, as do doc's face_loops and
boundary_loops, kernel's coplanar wire samples, CapLoop's segments,
tess pieces' rings, the gizmo's plane quads and the navigation cube's
facets. Their walks take edges() or corners() instead of wrapping an
index; sketch's text-hole test and doc's poly_area become contains and
signed_area. Loop2::joints pairs each segment with the next.
Replaces the ring_edges free function.

* geom: Chain, Ring and Path; bounds for a chain of points
Ring becomes Chain<T, Closed> beside Path = Chain<T, Open>: edges()
closes a ring and stops at a path's end, Path::close makes the ring,
and bounds() (the empty box for no points) serves both. Eight
hand-rolled min/max folds over a loop's polyline call bounds(); doc's
flat_polyline returns a Ring.

* geom: area and inside on Ring for any planar point
Ring's signed_area and contains take any Planar point (Vec2 or
[f64; 2]). The cam profile in joints_cam is a Ring: its own even-odd
test goes, and its edge walks, gap and area take edges(). face_params'
loop area, the text path's winding, tess pieces' ring area and the
copies in three tests call signed_area or contains; the formulas are
the same term for term.

* doc: sheet's closed outlines go through Ring
dedup takes and returns a Ring (dropping a last point back on the first
is what makes it a ring's), near_outline walks a Ring's edges, and the
copy of it beside fold checks calls it. point_in goes: its callers ask
the Ring. Its formula anchored each crossing on the other end of the
edge, so the two can differ only for a point on an edge to the last
digit; one caller sets such points aside first, the others test a
region's interior point, a cut's midpoint or another outline's corners.

Ring<Vec3>::area_vector is half the sum of a × b round the ring. heal's
loop_area, lip's outer-loop turning and the revolve's loop orientation
summed it by hand with a wrapped index; they take it from the Ring
(the half is exact, and two of them only read its sign).

* geom: Aabb3 from points; boxes built and asked through it
Aabb3 collects from points (skipping non-finite ones, as add does) and
gains inflated, contains and meets. Fifteen hand-rolled min/max folds
over points or boxes in kernel, doc and engine become collect or union,
and their "within tol of the box" tests become inflated(tol).contains.
blend's refused-edge boxes and naming's face index hold an Aabb3.
A NaN point is now outside every box, where the old negated
comparisons let it in; an infinite point no longer stretches a box.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* geom: Aabb2, the plane's box; 2D folds and box tuples use it
Aabb2 mirrors Aabb3 (collect, add, union, inflated, contains, meets)
and adds relative, a point's place in the box. sketch's link and
link_loops each had that formula; link_loops' boundaries, prism's
segment and loop boxes, profiles' shape boxes and grid, and ends'
segment box hold an Aabb2 instead of a (low, high) pair. Folds in the
cam, sketch bounds, sheet's perforation grid and the sketch clipboard
collect one.
Boxes are built from the same terms (a round's box keeps c - r - tol).
As with Aabb3, a NaN point is outside every box and an infinite point
no longer stretches one.

Chain::bounds returns an Aabb2. Its callers keep it: sheet's hole and
cut boxes (loop_box), letter boxes, island outlines and line-near-cut
test use meets, contains and inflated; profile's outline overlap and
max_clearance, profiles' box tests and the cam test read its corners.
flat_size and the flat pattern's JSON size are the union of the loops'
boxes (0 × 0 for no loop, where the pair fold gave -∞).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* geom: Aabb3::intersection; hand-grown and hand-met boxes use the box
Aabb3::intersection is the box both hold. ops' four overlap boxes of a
boolean's operands take it, and seven boxes grown by hand (ops' body
boxes, the distance set's bounds, coplanar's face box, eval_more's
padded mesh box, compare's group and region boxes) call inflated with
the same amount on every side.

* Prism boolean: a curved edge at one level crosses the walls there only (#1209)
The prism boolean sews its result slab by slab and keeps, for each section segment, the operand
wall it was read beside; its history is built from those tags. `Stations::new` took every curved
edge between two walls as crossing them at every level, so where two pieces of one cylinder are
stacked (an arm's round end under a boss of that radius) the circle between them cleared the
wall tags of every slab. `prism_lineage::sewn` then gave up, the join or cut came out with no
history, and every face of the body was named from geometry (`exact: false`).
A curve whose control points lie at one level (a B-spline, or a NURBS curve with positive
weights, which lies in their convex hull) is at that level: it crosses the walls there only.
Any other curve still spans every level.

A planar union no longer leaves a sliver where an edge crosses its neighbour, so a sheet whose outline runs on past a flange's edge with a slight bend unfolds again.
- A new cut was clipped against the panel with every one of its cut-outs, so
each hole of a perforation cost the square of all the holes before it and the
second cut of 500 ran out of the flat budget. A tool is now clipped against
only the cut-outs whose boxes meet its own (the same result).
- The planar booleans' point-in-loop test now skips loops whose box is clear of
the point, before the costly on-the-loop test; with a thousand holes that test
was most of the time.
The 1000-hole panel now takes about 15 s instead of failing.

Walls swept along a spline have flat B-spline tops and bottoms, so booleans between them went to the general intersection, which fails on coincident spline faces. Such faces are now put on true planes, and two prisms of the same height and direction are decided in 2D with their spline outlines fitted by arcs within a micron. The result is kept only when its volume is plausible; otherwise the general boolean takes over. The free-form flag is cleared by a drop guard so an unwinding boolean can't leave it set.
Fixes#844.
A coincident face is pushed apart only when the space it moves through holds nothing that changes the result; otherwise the boolean falls through to the exact strategies.

Sheet-metal cut-outs and base flange outlines drawn with ellipses, splines or text stay exact curves in the flat pattern and the unfolded body; the folded body follows them with tangent arcs within 0.001 mm (#659).
A flat face that no construction certificate names on its own now attaches by its exact history name (a new lineage face certificate): cut walls and floors, chamfer faces, each pattern or mirror copy, side walls a Join merged, and the pieces a later feature split a face into. Construction certificates still come first; a seed keeps its certificate when it is patterned. Two flush extrudes of one outline joined end to end keep their exact history in the prism boolean. Face sketch 52% -> 71%, offset plane 52% -> 71%, press-pull/extrude from face 41% -> 60% in the action matrix; baseline blessed.

Two line segments that lie on one another within the tolerance, a hair from parallel, no longer report a crossing somewhere along their overlap; the ends of the overlap split the edges instead. This stops booleans from leaving sub-tolerance edges or stray vertices.

Pattern copies of a post joined to a body already holding the original post had
their tops in its plane, so every join first pushed faces apart (about 190 ms,
then discarded). Faces now coincide only where their boxes meet, the push-apart
retry runs once per boolean instead of twice, and splitting prism outlines skips
the sampled arc projection for points off the arc's circle.
Sensor enclosure evaluation: 3.07 s -> 1.63 s, same bodies.

The planar arrangement solved a line and a circle, or two circles, for their two
crossings even where the curves only touch. At a tangent contact the two roots are
rounding noise spread along the curves by its square root: a 1e-12 mm error in the
centre's distance from the line puts them 2e-6 mm either side of the contact on a
2 mm arc, well inside the tolerance of both curves; when the noise falls the other
way there is no root at all. Cutting a rounded corner (an arc tangent to the two
edges it ends on) out of a plate with planar_regions_boolean then ran that far along
the plate's edge past the arc's end before turning onto the arc: a 200 x 37 plate
turned by 0.25 degrees came back with six edges, one of them 3.45e-6 mm long.
Curves that touch within the arrangement's tolerance now meet at the one point their
centres give: the foot of the circle's centre on the line, or the point on the line
of centres of two circles tangent inside or outside. Circles of nearly one radius
about nearly one centre keep the general formula.

* Tangent hole contacts: every symmetric contact gives the same faces (#307)
Three things made the four symmetric contacts of reference case 42 differ:
- The 2D prism boolean's ray-parity test miscounted a ray grazing the bottom
of a patterned hole, whose two halves are read back with centres a few ulps
apart: one half counted the touch, the other missed it. The loop chaining
then failed and those cuts fell back to the general boolean, which treats
circles tangent within its tolerance as overlapping and splits the hole.
The ray is now moved off vertices and arc extremes by far less than any
modelling tolerance.
- The prism result's volume check used a coarser mesh than the operands, so
a plate with many holes read too large and correct results were rejected.
- The merged topology did not join a hole's two pieces across the line where
two tangent holes touch (four faces meet there).
Case 42 now gives 39 faces (33 holes, 6 planes); its expected.json pins it.

A sheet-metal tray built at 2000 x 2500 mm with an edge flange on all four
edges (72° or 90°) and unfolded failed to rebuild when W and H went to
400 x 300, 600 x 450, or W alone to 400: "planar region arrangement failed
or exceeded its bounded processing budget". The same tray drawn at 400 x 300
unfolded, and growing it worked.
The sketch solved again after the change leaves its corners ~1e-13 mm off,
so the flanges inherit a hair of tilt and their panels and bend zones meet
the trimmed base within 1e-13 mm instead of exactly. The flat pattern is a
balanced union of those pieces, and the arrangement chains its output loops
within 10 tol. In a later round, ray parity classified a bend zone's edge
midpoint that lay level with a corner whose two lines did not quite meet:
the ray slipped through the gap without a crossing, the zone's edges counted
as inside the other operand and were dropped, and the outline no longer
closed. A rectangle turned by 1e-14 rad failed the same way.
inside_loop now closes the gap where one line ends and the next begins with
a straight connector while it counts crossings; exactly closed joints are
unaffected. Joints with an arc keep the arc's own endpoint rule, which
treats ends within its angular tolerance as on the ray (a connector there
double counted at a circle split into two arcs).

A cut of stepped prisms sews a wall over one segment through successive
slabs as one face, and the generated planar walls are then joined on
their common supports. Until now such a piece carried no history.
- prism_lineage: a sewn wall records what it is over in each slab it
spans (Spec::Wall { levels, slabs }), so a coalesced wall comes from
the operand walls under it in every slab
- the sewn piece's history is attached before the joining and carried
through it (Built::Traced); planar_regularize composes the history of
the body it joins with the join itself
- a composed face is Split only where record::mark_shared_split finds an
origin under several faces; an inner Split alone no longer makes one
- Body::same ignores history: an operation that leaves a body as it is
gives the same body, carrying that operation's history
The two boolean history tests that waited for this run again, and the
coalesced and regularized step cuts are covered.

The far edge of a stepped slab (the operand cap edge where a segment's
wall ends) was recorded by testing whether each slab segment runs along
an ending cap's segment in 2D, a tolerance comparison of coordinates.
Matching by topology makes the far edge exact by construction instead:
when the wall's top is the ending level, nothing crosses it there, and it
meets the caps at that level in exactly one edge, that edge is over every
segment beside the wall, with no position compared.
A vertex walk up the wall's side edges from the segment's ends was tried
first and does not settle the cases that need it: a notched or stepped
wall continues past a segment's end (no side edge rises from it), and
walls split by earlier stations have mid-chain vertices with no side edge.
Whenever the walk succeeds, the wall is a rectangle over the segment and
the one-edge rule above already holds.
The positional match remains only where topology cannot say which edge
is over a segment: a wall that meets the ending caps in several edges (a
top split at earlier station vertices, or beside a wall crossing it at
that level) or that carries on past the level elsewhere. It is documented
in `Section::mark_far` and its pair budget no longer stops topological
marking. Far edges are also only marked on the slab that actually ends at
the level (a gap level no longer revisits an earlier slab).

Chamfer is one of the most common features and is usually applied right
after a cut. A chamfer cuts with a prism cutter, and its history came out
None after four of the six common box cuts. Without exact history, any
reference to a chamfer face (or a face it trimmed) falls back to geometric
guessing in naming, which can silently re-attach to the wrong face.
Two gaps in the stepped-prism section tags caused it, both now closed by
bookkeeping at construction, never by sampling or geometric tie-breaks:
- Cap edge at the far end of a slab. A slab's section is read off the cap
where it starts and carried up to the cap where it ends; that cap's
outline can run along one wall in several collinear edges, so which one
a result edge lies on was unknown. When the stack is read, each slab
segment that runs end to end along one segment of an ending cap's
outline (beside the same wall) records that cap edge as `far`; the
lineage takes it when it bounds the wall and the result cap.
- Walls an earlier cut left in coplanar pieces. A segment carried through
a level kept the wall it was read beside, even where that wall gives
way to another piece at the level (or within the slab), so the tag named
the wrong face. `Stations` records the operand's edges across walls;
at each level a carried segment keeps its wall when nothing crosses it
there, moves to the one wall across it when it ends there, and is
otherwise unknown (no history). A wall crossed inside a slab is unknown
too, for simple and stepped prisms alike.
chamfer_after_box_cuts now covers all six cuts (notch, pocket, step,
slot, hole, bite), each verified against geometry and composed through
the cut over [block, tool]. The layered partial-depth cut test now
verifies its second cut, whose history was None before.

ops::boolean's result carries its history over [a, b] whichever path made
it, recorded by the code that builds the faces:
- truck path (incl. jitter retries): shapeops history mapped through the
order-preserving copies and the cut's turned tool, then through healing
- heal records which input faces each healed face merges and which input
edges each joined or exact edge replaces (HealMap); opt-in, so heal_keep
callers pay nothing
- trivial shortcuts, the void, glue, faces pushed apart (push_faces records
its own history; the slab cut back on a union maps to the operands'
faces in that plane), the nudged retry, by_lumps and join composition
- prism booleans: section segments carry tags (operand cap edge, the wall
beside it, its vertices) through the 2D boolean; walls, caps and edges of
the extruded or sewn result follow from them
- planar and faceted polygon booleans: polygons carry their operand face;
faces join the pieces across edges, edges come from the pieces either side
History gains renumber/over (and consuming forms) for composition;
record gains regions/traced/build helpers. truck-shapeops
*_with_history now return the solid with an Option history. Paths that
cannot report (bore narrowing via offset, inexpressible lineage) leave the
result without history. Boolean results, tolerances and fallback order are

Persist typed sketch dimensions and bounded ordered configuration rules in format 8. Use exact occurrence paths and source identity for editing, movement, appearance, and mass. Preserve sheet material regions through cutting, folding, and exact DXF export; retain nested cavities and material islands.
Validation: cargo xtask ci passed, including 368 engine tests, 178 UI tests, 68 UI scenarios, 136 kernel tests, and the 10-crate wasm check. Actual preview workflows and legacy format-7 origin-corner reopening were inspected.
