* Add a one-surface fill of closed 3D loops to geom
A closed loop of curves that does not lie in a plane has no exact surface;
the usual answer is one smooth face fitted over it. fill_loop does that:
- the loop's best-fit plane (Newell normal), with a frame chosen from the
loop itself so the result does not depend on where the loop starts, its
direction, or where the part sits
- the loop seen along that normal must be simple and must not fold or run
along the normal; otherwise it is refused ("not supported yet"), never
filled with wrong geometry
- one non-rational bicubic B-spline height field over the loop's box,
fitted by least squares to the loop's samples (The NURBS Book 9.4.1,
9.4.3, eq. 9.62/9.65) with a thin-plate smoothness term
lambda*A*int(h_uu^2 + 2 h_uv^2 + h_vv^2), A one grid cell's area, so the
fit is the same at any scale; only planes are reproduced exactly
- span counts per direction (long narrow loops fit), refined until the
loop is within tolerance, else refused with the deviation reached
bspline: bisected span search, basis functions on a stack array, one
clamping helper shared by curves and surfaces, one binomial helper.

* Patch fills non-planar loops of edges with one smooth face (#250)
surface.patch with edges refused any loop that is not planar ("not
supported yet: patching a loop that is not planar"). It now fills it:
- planar loops still get one exact planar face, but planarity is certified
conservatively: lines by their ends, B-spline/NURBS edges by their control
points, intersection curves by their samples lying on a support plane
within tolerance; a loop that can't be certified is filled instead
- other loops get one face from geom's fill_loop, bounded by the body's own
chained edges, whole (no split): its history is one generated face whose
edges are the body's, and it stitches back into a closed solid
- intersection-curve edges are sampled by a seeded, guarded double
projection shared by the planarity test and the fill (plane_fit)
- the face tolerance is 10x the planarity tolerance (documented: later
operations take the face to contain its edges within it)
- edge picking runs inside the guard; the geom->truck conversion is shared
with the T-spline sheets (spline_conv); the Newell plane fit is shared with
STEP import
Tests: 3- to 8-sided, concave (dart, arrow, plus), flat-corner, two-edge and
imported rims fill as one face and stitch closed (volumes against an
independent integral); finite mesh normals, same result for any pick order
or placement; non-height-field loops and too-fine detail are refused.

The Patch dialog's only test used a sketch profile. Picking the four
curved rim edges of a box cut by a sideways cylinder now makes one
surface.patch command whose result is a single smooth face over the rim.

* Sketch on a cylinder primitive's caps (#420)
A solid.cylinder's caps carried no construction certificate, so a sketch
on its top or bottom was refused unless fixed:true (#420's crossed
cylinders, built from primitives).
- kernel: FaceSource::CylinderCap { producer, high, plane };
Body::with_cylinder_certificate turns a cylinder's two extrude caps into
certified caps. kernel::cylinder's output is unchanged for its other
callers.
- doc: FaceCertificate::CylinderCap { high }, named F<id>:top / F<id>:bottom
as the cylinder's face names already are; New Body and Join cylinders
are certified, shells carry it as their planar source.
- format 15: designs can store the new certificate kind; version 14
designs need no change, and older builds ask for an update instead of
meeting an unknown kind.
Tests: top and bottom attachments follow a height and base edit and a
reopen; crossed joined cylinders keep both caps attachable; a shelled
cylinder's floor keeps its cap identity; malformed certificate JSON is
refused.

A Union dropped every construction certificate, so after any join no face
could take a durable sketch: sketch.create failed with "this face has no
exact planar source" even on a face the join never touched (#420, and the
"CREATE SKETCH: operation failed" reports #344, #195).
- kernel: map planar sources through a Union from both operands, with the
same exact-support rule Cut uses. Coplanar supports of the two operands
carry distinct identities, so a face merged from both stays without one.
- doc: Join extrude and Join box tools are certified like new bodies; a
cap moved off its designed height (into the target, or past a curved To
face) is not certified. Join producers are accepted when certifying.
Tests: both operands' faces attach and follow an upstream edit and a
reopen; a merged coplanar face is refused and fixed:true works; a face a
join covers whole is lost without moving to the new roof. Tests that used
a joined face as their "uncertified" example now use a merged face; the
trimmed-face case in a_sketch_on_a_face_stays_on_that_face now stays
attached to the surviving piece.

kernel::sew refused a solid with a thin planar face away from the origin: a slab
30 x 2 mm and 0.00013 mm thick with a corner at (-300, -200, 5), turned 0.45 rad
about x, failed with "sew: face 1: cannot attach a plane to a wire that is not on
one plane", though its faces are flat to 1e-14 mm.
truck's plane fit sums the cross products of a boundary's control points about a
centre and takes the points' sum for that centre (it divides by the number of wires,
not of points): eight times as far from the origin as a rectangle of four lines. The
sum is the same about any centre, but its rounding grows with the square of the
centre's distance, and on a thin face, whose normal is short, it turns the normal far
enough for truck's own 1e-6 flatness test to fail: truck finds the slab's four thin
faces 3.0e-7 to 2.1e-6 mm out of the planes it fitted.
A planar face keeps truck's plane wherever truck gives one. Where truck refuses, the
same fit is made on a copy of the boundary moved so that the mean of its control
points is the origin, and the plane is moved back; a boundary that leaves its plane
or has no area is refused as before.

A body of several pieces (a plate and the islands a cut leaves inside its
holes, such as letter counters) was written as one BREP_WITH_VOIDS whose
other shells were voids. Export now writes one solid per lump, each with
its face colours; a real void stays a void of its lump.

A full revolve of a profile with more than one edge on the axis (a spherical shell's half ring:
both radial lines lie on it) took the generic sweep, built in place. Truck tessellates the
degenerate faces those edges sweep reliably only with the axis through the world origin, so on a
sketch plane off it the body measured about a third too large (a shell from r 18.5 to 40, 10 mm
above XY: 324 339 mm³ instead of 241 561), and booleans with it failed or removed the wrong side.
Such profiles are now swept about an axis through the origin and translated into place, as
revolve_touching_axis already does for profiles with one edge on the axis.

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.

A cut-out made in the flat pattern could cross a bend only with edges
running along the bend or square to it: a round hole or a slanted slot
over a bend line failed to fold ("not supported yet: curved cut-outs
across a bend", "... cut-out edges running across a bend at an angle").
Sheet: a flat edge in a bend zone now folds whichever way it runs: along
the bend to a line, across it to an arc, and any other way to a curve on
the bend's cylinder (a slanted line to a helix). The curve is carried as
a chain of cubic Hermite pieces fitted within 1e-7 mm on both faces of
the sheet, with breaks that depend on the flat edge only, so the top
face, the bottom face and the wall share them. The wall between the two
chains is a ruled surface with radial rulings: the cut-out's wall stays
square to the sheet. The bend's own faces stay exact cylinders, now sized
to the whole boundary of their cell (a curved edge may bulge past its
corners).
Kernel: such an edge has no line, arc or conic form, so the sewing
interface gets EdgeSpec::Chain (a chain of cubic Bézier pieces: a cubic
B-spline with triple inner knots, its ends on the shared vertices) and
SurfSpec::Ruled (two chains joined by straight lines, so a wall built
from the chains holds them exactly). The sheet module's rev_edge becomes
EdgeSpec::reversed, so the new variant is handled where edges are
reversed.
The test for "along" and "across" is in millimetres (1e-6 mm at the
edge's ends) instead of relative 1e-9, so coordinates rounded by a script
fold as drawn.
Tests. Kernel: a box with one wall bulging as a cubic (chains of two
pieces at the bottom and the top, the wall ruled between them) sews to a
valid solid of the analytic volume, 27.6 (measured 27.59965); chains with
the wrong number of control points, a NaN or too many pieces, and a ruled
wall between chains of different piece counts, are refused. Sheet: a slot
turned 30° and a round hole across 72°, 90° and 108° bends fold to valid
solids that lose the cut-out's flat area times the thickness (K = 0.5:
400 and 100.53 mm³, measured within 0.02); a slanted flat edge folds to
its exact helix within 1e-7 mm (measured 1.9e-8) on both faces; lines
along and across the bend keep their line and arc. Engine:
fold_through_cut_outs now expects a round hole across a fold to fold, and
to unfold to the same round hole; the per-bend machining guard (#296)
sews a bend that carries a round cut-out, so a hole beside it cuts and a
hole in the bend is still refused.

* fix: fillet fit review follow-ups
From the review of #388 (merged before these landed):
- The Fillet dialog's Applied Radius showed nothing when editing a fillet
that was already reduced: the preview found the radius by diffing the
states before and after. The engine's preview now keeps the command
replies, and the dialog reads the radius of the feature they name.
- Pattern copies of a reduced fillet try the radius the original was
reduced to first, instead of each searching again (up to 16 fillets).
- fit: reduce with a chord or variable radius is refused instead of being
silently ignored.
- One helper appends a note to a feature's warning; too_large is imported
like unsupported in the loop and curve blends.

Every panic (in a command, in the kernel, anywhere else) and every unclean
exit (abort, stack overflow, kill) leaves a report in a local crash folder:
message, file:line, a trimmed backtrace, version, commit, system and renderer,
the command and recent commands, and when possible the design and replay.json
that reproduce it (solvecraft-cli crashes replay <id>).
- Cost: nothing until the app installs the hook (tests, CLI and web never
do); then one small journal line per top-level command of the design on
screen, taken back with a truncate when the command changed nothing.
- Unclean exits: each run holds a lock on its journal; a journal nobody holds
at the next start belongs to an app that died. Autosaves restart the
journal from the autosaved design.
- Bounded: a crash's signature (place + message, numbers ignored) is counted,
not rewritten; at most 5 new reports per run, 20 reports, 50 MB, 90 days;
recovered kernel panics are pruned first.
- Agents: diagnostics.crash_reports / crash_report / crash_reports.clear
commands, the MCP crash_reports tool, solvecraft-cli crashes, solvecraft
--crash-log; diagnostics.crash_test (with SOLVECRAFT_CRASH_TEST) checks it.
- People: the Crash Reports window opens after a crash (Help > Crash

- Release builds keep line tables for file:line in backtraces.
Tests: child processes that really panic in a command, in the kernel, on a

kernel::sew builds an arc edge, and the wall an extruded arc sweeps, with truck's
three-point arc (circumcentre, then a turn about it). On a very flat arc that
construction ends off its own vertex: a 12 mm chord with a 0.08 um sagitta (a 225 m
radius) ends about 1e-6 mm short of it, and the planar face holding the arc, 1238 mm
from the origin, fails with "cannot attach a plane to a wire that is not on one plane".
truck's plane fit takes the sum of the wire's control points as its centre, so a gap
of that size is scaled by a distance of the order of the coordinates and tilts the
estimated normal beyond the fit's 1e-6 flatness tolerance.
Arcs whose sagitta is under 1% of the half chord are now built as their exact rational
quadratic (apex 2/(1-t^2) along the bow, weight (1-t^2)/(1+t^2), t the sagitta over the
half chord), for edges and for the extruded walls on them. Deeper arcs keep truck's
construction.

* feat(kernel): typed TooLarge refusal and fillet_max search
Blend refusals caused only by the size (larger than the neighbouring faces,
taller than the walls, longer than the next edge, larger than a corner
radius) now return KernelError::TooLarge, displayed as before. fillet_max
finds the largest radius below a request at which the fillet of the edges
works, to three significant digits, by building candidates; it is an explicit
call (up to 16 fillets), not run on every refusal.
A corner edge that doesn't run square to the edge is now reported as such
instead of as a blend larger than the neighbouring faces.

* feat: fillet fit option reduces a radius too large for its edges
solid.fillet takes fit: exact (the default, as before: a radius too large
for the geometry around the edges is refused) or reduce: the radius is
reduced to the largest that works for all the picked edges (kernel
fillet_max, three significant digits, every candidate built). The feature
stores the requested radius, so it refits on every evaluation; when it
reduces, the feature's warning says so and the command returns
radius_applied. Pattern copies of the fillet use the same rule. The file
format writes fit only when it is reduce.
The Fillet dialog gets a Radius Fit row (Exact / Reduce to Fit, constant
radius) and, when the preview reduced the radius, an Applied Radius line;
editing the feature keeps the choice.
One radius for all edges for now; per-edge radii and taper follow.

* 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 straight-edge fillet required each end of the edge to meet exactly one more
face, square to the edge. Now an end may meet one planar face at any angle
(the round ends in it along an exact ellipse, the cross-section slid along
the edge onto the plane) or two planar faces meeting at the end vertex: the
round ends across both and cuts back the edge between them where its
cylinder crosses it (Vida, Martin and Varady 1994: trimlines joined across
existing faces). The cylinder is swept to cover both trimmed ends. Square
ends are built as before.
This rounds the mitres where two chamfers meet at a plate's corner, and a
concave edge where a post stands on a plate (the round's end caps extend
the post's end faces); both were refused.

Since 4e595de a partial-depth cut that ends inside a cylinder runs through the
exact stacked-section path, which leaves 0.3 mm wide strips of the cylinder wall
beside the cut. Their tessellation is one triangle wide, too few distinct
samples for the cylinder fit, so the merged topology reported them as a sphere
and a freeform face. Where the mesh fit finds no plane or cylinder, use the
face's exact surface (plane, cylinder or sphere) instead.

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).

* Add B-spline basis, knot insertion and NURBS surfaces to geom
Freeform faces need local refinement and gap-free joins between patches
with different knot vectors, which tensor B-spline grids cannot give;
T-splines can, and the first user is an N-sided Boundary Fill of
non-planar loops. This lays the univariate groundwork they rest on, in
the L0 geometry crate so it stays independent of the B-rep kernel:
- Cox-de Boor basis of one function from its local knot vector, on
half-open spans with a left-limit side for the domain end, with
derivatives (NURBS Book eq. 2.5, 2.9)
- knot insertion into a single basis function (Sederberg et al. 2004
section 3) and Bezier extraction of one function by repeated insertion
- Boehm knot insertion for curves (NURBS Book A5.1), de Casteljau
evaluation and sub-segments
- a rational tensor NURBS surface with evaluation, knot insertion and
clamping, and a rational Bezier patch type
All input is checked (finite, monotone knots, positive weights, size
caps) and returns SplineError; nothing indexes unchecked.

* Add T-spline surfaces: T-mesh, evaluation, AS check, refinement, extraction
Tensor B-spline faces refine only by whole rows and columns and cannot
join patches with different knot vectors without gaps. T-splines allow
T-junctions in the control net, which fixes both; the first user is an
N-sided Boundary Fill. This adds the maths only (no command, no change
in behaviour):
- T-mesh in index space with knot values per line, validated (outer
rectangle, rectangular faces, no empty lines, size caps); local knot
vectors read off rays from each vertex, rays leaving the mesh repeat
the boundary (Sederberg et al. 2003 section 3)
- rational T-spline evaluation and first derivatives for odd bi-degree,
with a complete (p-1)/2-line frame and the domain inside it
- T-junction extensions and the analysis-suitability check (Scott et al.
2012 section 2)
- local refinement that keeps the surface exactly: requested knot lines
are cut in, then every original blending function is carried as a
record and split (violation 1) or the mesh gains edges (violations 2
and 3) until each record is a blending function of the refined mesh
(Sederberg et al. 2004 section 3); analysis-suitable input stays
analysis-suitable by carrying conflicting T-junctions across faces
- NURBS <-> T-spline conversion for meshes without T-junctions, and
Bezier extraction over the rectangles no blending-function knot line
crosses
Measured: regular T-spline vs NURBS < 1e-12, round trip exact, partition
of unity with T-junctions < 1e-14, refinement deviation <= 1.4e-14 over
40 random refinements, Bezier patches vs surface < 1e-14.

* Convert T-splines to sewn NURBS sheet bodies in the kernel
A T-spline is only useful to the modeller once it is a B-rep face set.
tspline_sheet builds an open shell: a mesh without T-junctions becomes
one clamped NURBS face; otherwise each Bezier element is a face, and
sides are split at the T-points where neighbours' corners land, so all
faces share vertices and edges and the sheet is one oriented shell
(V - E + F = 1). Every truck call runs under guard. No command yet;
Boundary Fill will be the first caller.
Tests: one face for a regular surface, sewn Bezier faces with
T-junctions, tessellated points on the surface to ~1e-9 mm, and hostile
control nets (coincident, 1e300, needle-thin) never panic.

* Loop blends accept straight wall seams that are not lines
Filleting or chamfering the top outline of two overlapping cylinders whose
concave edges were rounded failed with "the wall seams must be straight":
the round's contact lines with the cylinders are straight NURBS curves, and
the loop blend only accepted seams stored as lines. A seam now counts as
straight when every sample lies on its chord; it is trimmed as a line as
before.
* Fillet and chamfer arrows point into the body
The radius arrow pointed out of the body along the edge's bisector, so
dragging it away from the edge grew the round. It now points into the
material, like the shell's thickness arrow: dragging toward the body grows
the radius or distance, dragging out of it shrinks it.
* Toolbar: no cap on pinned buttons (Fixes#323)
Every pinned command gets a toolbar button; `promoted()` is only the
default layout of a fresh or reset toolbar. A toolbar too narrow for every
button now collapses panels into their drop-down (one button that opens it,
listing every command, pinned ones included) from the right, then moves the
last panels into the » menu, instead of pushing a wide panel and everything
after it into ». Nothing is dropped.

narrower still puts it in », and Reset Toolbar restores the defaults.

* fix(kernel): loop fillet as tall as its wall uses the wall up
Rounding a loop with a radius equal to the height of its walls was refused
("the blend is taller than the walls"): r = 2 on the top edge of a 2 mm
disc failed while 1.999 worked. When every wall seam ends exactly where the
wall-side rail would, the walls are consumed: their far edges become the
blend's rails and the walls and seams are removed. Walls used up only in
part, and radii past the limit, are still refused.

Why: every reference a user makes to a face or edge (fillet and chamfer
edges, sketches on faces, shell/draft/offset faces, joints, appearances)
is stored as a name and found again after any upstream edit. Those names
were re-derived by sampling points of each face and voting, and pieces
of a split face were numbered by where their centres lay. After an
upstream edit that splits, merges, mirrors or shrinks a face, a fillet
or sketch could silently re-attach to the wrong face, and nothing told
the user. The kernel now reports exact history for its operations, so
names follow it and fail loudly instead of guessing.
- crates/doc/src/lineage.rs: a feature's kernel histories composed into
one lineage over nameable operands (bodies before the feature, moved
copies, shell cavities, tools named by role: sketch curve, cap, box
side, imported face). Instrumented: extrude/revolve/sweep/loft tools,
join/cut/intersect, lumps after a cut, fillet/chamfer, shell, draft,
split face/body, pattern/mirror (bodies and features), combine,
boundary fill, move/scale, offset/delete face, thread, import.
- crates/doc/src/history_names.rs: names from lineage; split pieces told
apart by the faces only they touch (F2:top#[F2:side:l4,F4:side:l4]),
merged faces answer to every name (aliases), lump bodies ordered by
their faces' names instead of shell order.
- crates/doc/src/name_lookup.rs, piece_names.rs: references resolve by
exact name, alias or bounding faces, else nearest piece with a
warning; names worked out from geometry (operations without history)
are reported when only geometry decided.
- Format 14: names stored by older formats get a legacy mark and are
found as the build that saved them found them (some geometric names
name a face history names differently: a tube's outer wall was named
after its inner circle). New corpus file saved by 9a979cf.
- kernel: Body::lumps carries each piece's history over the whole.
- Adversarial tests: split, merge, mirrored twins, shrink to a sliver,
moving cut with body pieces, history-less bodies, certified sketch.
- docs/book/src/dev/naming.md describes the real mechanism and why.

union_apart joins bodies whose boxes are clearly apart (many pattern tools,
#261) without any intersection work: their shells side by side. Each face
and edge of the result is its piece's own, unchanged, and the result now
says so (a history over the pieces), so a pattern's cut keeps the exact
names of every copy's faces.

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.

EdgeOrigin::Meet now names each side as a Side: the sorted, de-duplicated
origins of the face there. substitute maps a side to the union of the inner
faces' origins, so a meeting with a face an inner operation merged keeps its
lineage; meeting() derives sides from whole faces. Fillets after box cuts
that leave coplanar pieces now report exact history. Prism lineage meets a
cap of several origins and resolves wall junctions away from shared
vertices by the operand's one edge between the walls. bore_union's recut
reports history only for a one-face bore (pieces of a two-arc bore's recut
wall were given both arcs).

Fillets (local, loop, rolling ball, corner, variable, chord), chamfers
(cutters, local corners, loops, two sides), shell, draft, offset faces,
split face/body, delete face, patch/copy/stitch/trim/extend and
transforms record their history over [body] while they build: faces
rebuilt from the body's, blends in place of edges (corner patches in
place of the edges at the corner), shell walls as offsets, edges as
pieces of the body's or where two faces meet. Multi-step operations
compose each step. The push-face offset fallback now has history, and
the bore union composes its narrowed tool.
A reflection reorders a body's edges, so transforms now match edges by
identity (mirrored copies reported the wrong edges).

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
unchanged.

One numbered loop type (crate::numbered) carries each segment's profile
numbers through orientation, snapping, circle re-seaming, re-sampling and
rotation; every builder orients its regions through it once. Builders that
make their own side faces pair each face with its provenance as it is made
(ruled walls by the wire edges each face holds, smooth lofts, coils and path
sweeps by segment), and cap_and_close appends the caps itself. Column
following is kept only for faces truck sweeps internally (rsweep, tsweep
along paths, cones, where an apex vertex stays put). Extrude derives face
sources and history in one topology pass. One attach entry point takes
operands with their edges already indexed.
Geometry, face order, face sources and recorded origins are unchanged.

Extrude, revolve (partial and full turn), tapered extrude, loft (incl. to a
point), sweep, path sweep, coil, primitives, lip, emboss and thicken attach
the exact history of the bodies they build: each face's profile segment, cap
or operand face, and each edge's operand edge, recorded by topology identity
inside the building call. Nothing is sampled; a body whose faces do not follow
the expected construction carries no history. Face sources are unchanged.

Bodies can now carry the exact history of the operation that made them:
for each result face its origins among the operation's operands (kept,
modified, split, merged, or generated from a profile segment, cap, edge or
offset) and for each edge the faces it separates and the operand edge or
face pair it came from. History is recorded by the operation, never
sampled, and checked against the body when attached.
- history.rs: the vocabulary (moved from provenance.rs), History::check,
identity, substitute (composes an operation with the one that made an
operand, including bodies made from a sketch) and face-source propagation.
- One edge order for a body (body::edge_order), shared by tessellation and
history, so history edge indices are the mesh's edge indices.
- Transforms report an identity history; placed_topology documents the
face/edge order guarantee it relies on.
- provenance.rs keeps the geometric trace for operations that do not yet
report history.

A constant-radius fillet whose setback equals the width of a neighbouring
face was refused ("the blend is larger than the neighbouring faces"), so
r = 3 on the vertical edges of a 6 mm wide box failed while 2.999 worked.
The corner edge is now consumed: the rail ends at its far vertex and a side
face used up at both ends is removed, its remaining edge becoming the rail.
A face used up at one end only, and radii past the limit, are still refused.

* test: reproduce #261 (Rectangular pattern of a hole cut scales super-linearly)
* Patterns of many hole cuts scale near-linearly (#261)
Two quadratic costs:
- Meshing a face tested every point against every segment of every boundary
loop, so a plate face with hundreds of holes meshed in quadratic time. The
vendored truck-meshalgo inside test now skips loops whose parameter box is
clear of the point (they wind zero times around it).
- A pattern cut each copy in turn, rebuilding and re-checking an ever more
complex target per copy. Copies whose boxes are clear of each other are now
one tool of many pieces (kernel::union_apart, no intersection work), cut once.
512 holes now take ~7 s instead of not finishing. The test's volume tolerance is
widened from 1e-6 relative to 0.1 % of each hole: the measure meshes the bores
and reads each hole ~0.06 % small, on main too.

* Hole-pattern test: a budget CI can meet; coarser apart-box meshes (#261)
CI runs every test binary at once and is about ten times slower than a
machine running this test alone (15 tests passed 60 s in the last run), so the
512-hole pattern (about 6 s alone) hit the 60 s timeout there. The budget now
only has to tell linear from the quadratic hang: 300 s timeout, 120 s budget.
union_apart meshes each copy coarsely (2 % of its size, box grown by twice that).
Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Hole-pattern test checks the scaling, not a wall-clock time (#261)
CI runs every test binary at once: the 512-hole pattern (about 6 s alone, 10 s
CPU single-threaded) took 177 s there, so no fixed time is reliable. The test
now patterns 128 and then 512 holes and requires the second to take under 8x
the first (linear is 4x, measured 3.5-4.2x here; the old quadratic cost was 16x
or more), each with the volume check and a 900 s hang guard.

* test: reproduce #268 (Panic from truck-topology lib.rs:186 when joining struts that end on a bore wall)
* Sew refuses edges whose ends weld to one vertex (#268)
The sewer welds vertices on a 1e-6 grid but only rejected edges shorter than
1e-9, so a sliver edge between the two welded its ends into one vertex and
truck-topology panicked ("Two same vertices cannot construct an edge") inside
the guard. Such an edge is now a degenerate-edge error before any truck call,
and the boolean takes its usual fallback.

* Fillets along a straight edge between two cylinders: the rolling-ball blend trims curved cap edges to its contacts
The edge where two overlapping extruded arcs meet is a straight line between two cylinders
ending on planar caps. The rolling-ball blend built its sections and surface, but only
straight seams could be shortened to the contacts, so a circular cap edge was refused with
"a curved edge where the blend ends". Curved seams now keep the part of their curve between
the new ends, found from the nearest of a few samples (a search from the far end of a long
arc can settle on the opposite side of the circle).
The ball's surface projections start from each face's last answer instead of a cold search,
falling back to one when the warm answer leaves the surface's parameters or is farther than
the last point: about 4.5x faster per fillet (370 -> 80 ms), so dragging the radius is usable.
Fixes#237
Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Curve blend: refuse a closed curved seam where the blend ends
A seam that starts and ends at the same vertex (a full circle) has no
"between" two contacts, so trimming it built a broken edge. Return
"not supported yet" instead. The curved-seam trim moves into
trim_curved_seam so it can be tested directly.
