* Fix recovery for unsaved background tabs (#2884)
* Recovery: scheduled autosaves of every tab write on the worker thread (#2884)
After #3139, Autosaver::save waits for the write and Autosaver::tick runs
it on a worker. The scheduled path now goes through tick (which skips a
tab whose previous write is still running), so several dirty tabs no
longer write on the window thread each interval (#3044). save stays for
Save, close and shutdown. Each tab's autosaver has no clock of its own:
the shared cadence decides when it is due. The tests wait for the
writes a tick started.

* Recovery: closing a tab waits for its running autosave before removing the entry (#2884)
With the autosave on a worker thread, discard could remove the files and
the lock while a write was still running; the write then recreated the
entry without a lock, and the next launch offered a design closed with
Don't Save. discard now ends the running write first, as Drop does.

A feature's name labels it and builds nothing, but a timeline rename evaluated
the whole design again (about 70 s on the Prusa Core One assembly, and again
for undo). When the only change is one feature's name, the model renames its
result, sketch and construction geometry in place and takes the renamed
design's fingerprints. A rename other features follow (a plane a sketch is on)
or of a failed feature still evaluates the design.

A closed loop whose joints meet a few nanometres apart along their parallel
axes (faces modelled that far apart) passes the conflict check, but the loop
solver wanted 1e-7 mm before it moved anything. No value of a planar loop
takes such a gap out, so every drive of it stopped at once (stopped_by_loop,
fraction 0) and joint.reach called the loop open.
The solver now closes such a loop as far as it comes and, when what is left
is within the conflict check, keeps it that closed on the way. joint.drive,
joint.reach and the nearby pose of the dof count share it.

Display meshes triangulate a trimmed face in parameters scaled by the

On an imported part with 2.5 million triangles, every frame of a Section
Analysis drag looked up the picked face's plane several times (each lookup
tessellates the whole body, about 0.1 s) and cut every triangle again for
the outline (38 ms).
- planar_face keeps its last answers for the model state they were found in.
- The outline cuts through a SectionIndex: the mesh's triangles sorted into
slabs along the cut's normal, kept per mesh while the normal stays, so a
cut looks at one slab (0.06 ms on that part) and finds the same segments.

face to face - where the crossing strip is smaller than a face triangle -

A body rename changes names only, but committing it went through the general
"design changed" path: the whole timeline was evaluated again. On an imported
assembly that means reading the STEP file again and meshing every body (about
100 s on the Prusa Core One, and the same again for undo).
When the only change from the previous design is one body rename (the
features' stored body names and the body-keyed maps the rename updates), the
model now renames the body in its results instead: every body keeps its
geometry and meshes, and the fingerprints are set to the renamed design's so
the next evaluation reuses everything. Undo and redo of the rename take the
same path. A rename the model can't follow that way (the body is changed or
named by a later feature, sheet metal, threads) still evaluates the design as
before.
`bench-open --ops script.json` times commands and their undo on an opened
design, with the view work each leaves.

sketch and curve a swept side came from), whether the origin resolves and
why not; plus kind, offset, angle, flip, values with limits, expressions,
the motion links it is in, and its solve errors and conflicts. Its id ends

(`joints: false` leaves them out). joint.list and joint.inspect share the

`sketch.trim.path {points, dry_run?}` walks a polyline and, at each place it
crosses a curve trim may change, removes that piece exactly as `sketch.trim`
would there, in the order crossed and in one undo step. A piece already gone
is not trimmed again; projected geometry, infinite lines, offset outputs and
pieces trim refuses are passed over (reported in `skipped`). It returns each
trim's result and each removed piece as a polyline; `dry_run` reports them
without changing the design.
With Trim on, a press and drag in the viewport draws that path: the pieces it
would remove light up (a dry run of the command) and letting go runs it. A
click still trims the one piece under it.

When every route of the general boolean fails, it falls back on the sampled answer

even when the bodies' facets cross well past their faceting error. For an
intersection that keeps exactly the material it was asked to trim: teeth standing
0.27 mm out of a trimming cylinder came back untrimmed, and `solidcraft-cli run`
exited 0 with a part 16.918 mm in radius.
An intersection whose sampled answer is contradicted by facets crossing by more than
twice the depth the warning reports (6 x the check mesh tolerance, three times the
faceting error of two meshes) now fails, and the model is kept. Cuts and unions keep
the fallback: shelling a body in two pieces relies on it (a cavity tool grazing the
other piece), with the same depth and ignored volume as this case.

* Sheet metal: refuse a flat pattern that no longer matches the body
A feature that is not sheet metal can change a sheet body's material
without its sheet model knowing: a mirror combined into it, an extrude
joined onto it, a fillet or chamfer on a corner. The flat pattern, the
DXF and the bend table then wrote the sheet as it was before, a part
other than the one in the design, with no warning.
The evaluator now notes, per sheet, the first such feature: one that
changes the body's shape while its sheet model stays the same. That
feature warns, and sheet.flat_pattern, sheet.export_dxf (also with
per_body) and sheet.export_bend_table refuse with "not supported yet",
naming it. A sheet metal feature, or machining the sheet keeps as
cut-outs, rebuilds the body from the model: it clears the note and
warns that the change is not kept. Moving the body, splitting its faces
and cosmetic threads leave the flat pattern as it is.
* Sheet metal: a modelled thread is refused in the flat pattern too
Only a cosmetic thread leaves a sheet body's material as it is. A
modelled thread cuts the thread profile into the hole, which the flat
pattern does not have, and a later sheet metal feature dropped it
without a word. It now marks the sheet like a fillet does: it warns,
the flat pattern, DXF and bend table refuse naming it, and the feature
that rebuilds the body says the thread is not kept.
A loft through two sketches on the same plane built a flat body of zero
volume and reported success, so the mistake surfaced later, if at all
(a measure of 0, or a boolean that did nothing).
`loft_wires` now checks each pair of consecutive sections: parallel
planes with the second section's centroid in the first's plane are
refused with "loft sections i and i+1 lie in the same plane (no volume
between them)". The tolerance scales with the section's distance from
its plane's origin.
Test: two circles on XY; the loft fails with that message and leaves no
body.

`PlaneRef::walk_exprs` stopped at `Flipped`, so a sketch created with
`flip` on an offset plane (`{plane: "XZ", offset: "d", flip: "x"}`) did
not list the offset as an input. Changing `d` rebuilt nothing that read
the sketch, and the model went stale.
`Flipped` now continues to its base, as `Offset` and `AtAngle` do, in
both `walk_exprs` and `walk_exprs_mut`.
Test: a loft between XZ and a flipped XZ plane offset by `d` has the
volume for d = 30, and for d = 50 after `parameters.change`.

* claim: Convert to Sheet Metal keeps a plate where it is
* Convert to Sheet Metal keeps a plate where it is
Converted without bend edges, a plate moved by one thickness: a 100 x 60 x 2
plate on XY came out at z -2..0 picked on its top face, 2..4 picked on its
bottom. The sheet's frame (its base panel's bottom face, thickness along its
normal) was put on the plate's far face facing away from the picked face, so
the material grew out into empty space.
The frame now lies on the picked face with z into the material, as Convert
with bend edges does. The sheet is the old one moved back by the thickness:
same orientation, flat pattern, flange directions and pocket layers.
A test converts the plate from either face and checks its bounding box; the
engraved-plate test now checks the plate's position, not only its thickness.
Autosave serialised and wrote the whole design on the window's thread: about
120 ms on the Prusa Core One assembly (its 61 MB STEP text inside), a hitch
once per interval after every change, and more once saves keep the evaluated
model. A tick now takes a snapshot of the design (its Arc and what is hidden)
and writes it on a worker; a later tick takes up the outcome, and no new write
starts while one runs. Crash replays rebase onto the autosave only when the
design is still the one written. Save and close still wait for the write, and
dropping the autosaver lets a running write end.

the feature. `scripts/param_audit.py` summarises a test run's audit logs, and the schema

`solid.box` (`hole_face_tests.rs`) and `symmetric` on `solid.extrude` (`face_tests.rs`).
Both are removed, so the tests build what they always did. Comments no longer call

truck placed a face that no intersection divides (every face of a shell
that meets nothing of the other) by counting the faces a ray crosses,

counted the wrong way, and an inward shell (a void, a cut's inverted
tool) was read as a solid: a cut beside a sealed void came out empty,
refused or, with a tool whose bounding box covers the target, taken with
the body gone. Intersections of such bodies came out empty as well.
In an AND the crossings now count as each face is oriented, and an
inward shell holds what lies outside it. An OR keeps truck's count.
The corrected cut let a folded offset through: an arc edge next to a
face it meets tangentially had its ends moved past its middle, and the
arc went the long way round (robustness seed 73's shell). The offset
refuses an arc whose middle crossed its chord, as it does a straight
edge that turned round.

* kernel: a blend runs along chains of several faces and lines closed rims up (#764)
A blend's chain may run along the boundaries of several faces (a tube's rim
along the halves of its wall): each edge continues from its own best-facing
face, read station by station. Before, a chain had to be the edges of one face,
so every rim of a revolved or cylindrical surface was refused.
Two closed chains blend from matching seams: the second chain's start (searched
by arclength, then narrowed) and direction are the ones that put each station
closest to its partner, so rims whose seams sit apart no longer twist. A
picked `seam` point on each chain fixes the start instead. A closed chain
against an open one is refused. Closed chains leave towards each other's
centroid, not a point on the rim.
Stations are read on the edges' own curves, not on the chords of the length
table (they sat up to the chord's sagitta inside a curved edge), and the
reported gap is measured to the curves.

A station where a tube wall's two halves meet sits at a corner of one half's
parameters; with a leave direction that turns round the wall (tubes off each
other's axis) the shape could not be read there and the blend was refused. The
neighbouring chain edge's face holds the same point and reads it.

* blend: review clean-ups (#764)
- ChainLine keeps one list of samples instead of four parallel lists.
- frames_on and boundary_gap take the chain's ChainLine instead of rebuilding it.
- A station is read on the neighbouring face only when it sits on the vertex the two edges
share, each face once, and each face keeps its own walk.
- The seam rule (a closed chain starts at it, an open one runs from the nearer end) lives in
ChainLine::start_at_seam; pair_with reuses the start of its both-ways search.
- support_faces projects with curveblend::project; loop_area sits with plane_through.
- surface.blend parses `align` and `seam` through one point_pair; the Blend and Ruled dialogs
share body_and_edges.

A cut whose tool ends exactly on a face of the target (a hole cut from a pocket's floor up to the
plate's top face) could come out of the general boolean with the target's face whole over the hole
and the tool's end face under it: a skin of no thickness that keeps the hole closed. No volume
shows it and the sampled membership checks see the hole either way, so the result was kept. The
result check now refuses a body with a planar face lying back to back on another of its own planar
faces with nothing behind part of it (`coplanar::has_skin`), and the retries take the cut.

* Iterate instead of indexing in nine loops
Replace index loops that look up neighbours by position with enumerate,
zip(cycle().skip(1)) for wrap-around pairs and zip(skip(1)) for
consecutive pairs. No behaviour change.

* 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.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* 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.

* geom: area_vector on Ring<Vec3>; three Newell sums use it
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.

* kernel: prism's segment boxes are plain Aabb2s
The SegBox alias named a (low, high) pair; Aabb2 says it itself.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* geom: Chain::bounds is an Aabb2; the boxes #2382 left as pairs follow
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.

A line and a circle or arc can now be dimensioned to the circle's edge
(ConstraintKind::LineCircleDistance, saved as line_circle_distance): the gap
while the line misses the circle (0 is tangency), or how far the edge reaches
past the line when it cuts through (stored as `inside`).
Rebased onto main as one commit (the branch's own changes; its merges of main
dropped). Conflicts resolved: the test mod lines in cmd/sketch.rs (both kept,
sorted), and README.md, whose feature list main moved to docs/capabilities.md;
the line-to-circle dimension is listed there now.

Two empty numerical cut attempts stopped the boolean retry sequence before
the exact geometric strategies ran. When the result guard refuses that empty
candidate, the exact strategies (sliced planar, pushed walls, local prism,
sphere lens, seam halves) now try the cut first; if none recovers it, the
original empty candidate and diagnostics are kept, before any displaced
numerical retry.
Rebased onto main as one commit (the branch's own changes, its merges of main
dropped). The only conflict was the new engine regression test next to
main's #1985 STEP export tests in boolean_regression_tests.rs; both are kept.
* kernel: loft guide rails (#201)
A loft follows one or two guide rails between its sections: stations are added between each two
sections, each the plain loft there moved so that the point a rail guides lands where the rail
crosses the station's plane — turned about the loft's direction and scaled (or stretched across
to the rail) with one rail, carried, turned and sized between two. The sections and caps stay
exact; the smooth loft runs through sections and stations. Solid and sheet lofts.

`rails` (one or two {sketch, curves}) and `rail_fit` (scale | stretch), stored on Loft and
SurfaceLoft (one pending format note), parsed by the sweep's rail parser (now shared) and built
through the kernel's railed loft. Rails on a loft to a point, or on a surface loft with edge
sections or end continuity, are refused as not supported yet. The rails' sketches are walked as
the feature's references and their components placed like a sweep's.

* loft rails: review clean-ups (#201)
- Sweep and loft rails share one turn-and-size map (`sweep_path::rail_frame`).
- A station's middle and the loft's direction come from one curve through the sections'
middles (exact derivative) instead of two more plain-loft evaluations per station; at most
33 wires, so railed faces stay light.
- Nearest points on a section use `param_on` (kept only where the search comes nearer); the
size uses `Aabb3`; one B-spline builder; anchors keep their nudge.
- The railed and plain lofts share one path in `loft_with_rails` and `loft_sheet_with_rails`.
- The engine leaves the not-yet-supported refusals to the design's evaluation; both lofts start
their rails from the first section's first point.

* Sheet metal: a corner relief no longer depends on the order the corners are cut in
The corner reliefs are planned against the base as it is before any of them is
cut, and the two reliefs at the ends of one edge are compared with each
other. Before, every relief was cut into the base as it went, so the corner
after it saw the relief of the corner before it: the square relief reaches
further from its corner than the round one does (4 / cos(α / 2) against 4), so
on a short edge it was left out where the round one was cut, and which of the
two corners kept its relief depended on the order the flanges were made in.
The reliefs themselves are unchanged: a round about the corner through the
angle the base fills there, or the square with that side (a kite where the
corner is not square, its cuts square to the two edges). What is new is that
they are planned first and cut together, so that a corner's relief depends on
the base and on the other reliefs, and not on the order they are cut in. Two
reliefs that would overlap are still refused, now with a note that says so.
Covered: the four relief shapes at corners of 60° and 120°, with the flanges
of equal and of unequal height, through the kernel and through the engine
(where the flat pattern and the DXF keep one clean loop).
Co-Authored-By: Claude Code <noreply@anthropic.com>
* Sheet metal: cover the corner reliefs at a corner that is not square
The engine and the UI had no test at all for a base whose corners are 60° and
120°: the flat pattern, the DXF, the unfold and the rule manager's own square
relief were all untested there. They work; this says so.
Co-Authored-By: Claude Code <noreply@anthropic.com>
* Sheet metal: say what happens when a corner relief is left out
The guide now says that the reliefs at the corners of one edge are cut
together, and that two of them that would overlap leave the second one out.
A relief that cannot be cut is reported, not dropped.
Co-Authored-By: Claude Code <noreply@anthropic.com>
* Sheet metal: write the corner relief's expected corners out
The engine test hard-coded the corners of the trimmed base; it works them out
instead, and the numbers the test and the sketch share are written with the
precision they need.

Save ran on the window's thread: about 130 ms on the Prusa Core One design,
and more than a second once saves keep the evaluated model. The toolbar's
Save and Save As now run the command on a scratch copy of the session on a
worker; the design waits for it as it waits for a file picker (commands are
refused meanwhile), and the outcome is taken up as running the command here
would have left it: the name and links the save gave the design, its file,
its saved state (`Session::adopt_save`), the echo, the error status, the
recent files and the home thumbnail. A tab closing or the app quitting after
Save waits for the write, as does the app's exit. Scripts, the control
channel and the browser build still save in place.

* inspect.clearance: pairs whose bodies did not change are not measured again
Each clearance check measured every close pair again, though between two
checks usually only a few bodies change or move. Results are now kept per pair,
keyed by both bodies' geometry and placement and the check's settings; a pair
whose two bodies are unchanged is taken from that cache. With 40 overlapping
parts, a check after moving one of them took 0.8 s instead of 23 s (741 of 780
pairs reused). Pairs that could not be worked out are tried again each time.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* inspect.clearance: boxes and placed keys exactly as before the reuse
The pair boxes are taken over the mesh's triangles with finite corners, as a
distance shape's are, so pruning is unchanged. A placed body's identity now
includes its model body's own frame, so two placements are never mistaken for
one another.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* inspect.clearance: a large body is meshed once for all its pairs
Each pair that touches cuts the larger body down to the pair's region with a
kernel boolean, and that boolean meshed the whole body twice: once for its
checks and once inside the intersection. A sheet with 600 faces paid about
2.5 s per pair for meshes that were the same every time.
A body can now keep its meshes for reuse (Body::keeping_meshes); its booleans
take the meshes from there, and the intersection takes its shell meshes
from there too (truck-shapeops: and_with_history_meshed). Clearance uses such
copies for one check. Results are unchanged to the bit. On a 3 x 2 m sheet
with bends and 300 holes, the clip took 0.23 s per pair instead of 2.6 s, and
24 rivets took 5.6 s instead of 16.5 s.

* inspect.clearance: pins on one cylinder with their hole are answered or reported in seconds
A pin seated line to line in its hole, on its axis, and with a blend running into its wall
(a fillet under a head) sent the boolean through minutes of retries that ended unchecked; a
pin a hair off its hole's axis was passed as clear. Clearance now asks first whether the pair
holds such a pin (from the faces' surfaces alone). On its axis the boolean gets a few tries,
which answer plain pins at once; a hair off, or when those tries fail, the shared volume is
worked out apart by coaxial_overlap, which now also takes the zero-offset, equal-radius case,
moves the hole's wall when a blend keeps the pin's from moving, and checks its band more
tightly. What neither answers is reported as unchecked, naming the pin.
The kernel gains with_attempt_budget: the booleans run inside it get a number of tries of
the kernel's own intersection between them, the same on every machine.

* inspect.clearance: the bodies left whole meet their booleans with their meshes kept
A body that meets several others at one size (a bracket with balls pressed into it) was
meshed again for each pair's intersect: only the clipping used the copies that keep their
meshes. The intersect, the pin work and the union check now take those copies too.
