* STEP import: mesh band faces that wrap around a closed surface correctly
Fixes two related bugs that caused SolidCraft to fail to mesh a face wrapping
all the way around a closed, non-periodic surface (a revolved ridge band, or a
tube-shaped B-spline surface): a missing face, a folded/self-overlapping
triangulation, or a hole in the rendered body.
1. Ring edges that run slightly off their surface. STEP files write a surface
and the curves bounding it to the file's own declared uncertainty, so a
ring edge can legitimately sit a few micrometres off the surface it
bounds. The code finding where a ring edge crosses the planned split line
compared against the edge's raw (off-surface) point using a hardcoded
tolerance far stricter than the file's own precision, rejecting a valid
cut. Now matches against the point on the surface directly below the ring
crossing, respecting the file's declared tolerance.
2. Closed B-spline surfaces, their slits and their slivers. truck only treats
the rotation of a revolved surface as periodic; a face on a B-spline
surface whose control net closes on itself (a tube) wasn't recognized as
wrapping around at all. This produced a folded face, a hole (a boundary
loop landing a full period away from where it should cut), and one
near-zero-width sliver face costing the entire body its tessellation
plan. Adds periodicity detection for closed B-spline surfaces, period-
aware hole-loop alignment, dropping of zero-width slit boundaries, and
isolating a too-thin-to-triangulate face so it no longer takes the rest
of the body down with it. The GPU shader's periodic wrap mirrors the CPU
math so the two don't drift apart.
Regression tests: band_faces_split_when_ring_edges_run_off_their_surface,
band_face_with_a_zero_width_slit_is_still_meshed,
a_sliver_face_too_thin_to_triangulate_does_not_cost_the_body_its_plan.
Ablation-tested: disabling either mechanism in (2) reproduces its target
test's original failure message while leaving the other test unaffected.
* STEP import: mesh the band's split faces, not just split them
jyviko asked whether a band wall missing from the interactive app's render
was a shading issue or a genuinely missing face. It was missing: the ring-
edge split fix made the band's topology correct, but plan_face still
produced zero triangles for the two new sub-faces.
Two causes, both in plan_face (crates/kernel/src/tess/mod.rs):
1. The tolerance for how far an imported boundary may lie off its surface
was tied to the requested mesh's chord tolerance instead of to the
body's own size. A finer display tolerance could then reject a boundary
a coarser one had just accepted, so the face would drop out exactly when
zooming in on it.
2. Near a sharp corner of this flat-panelled band, several boundary points
that are legitimately a few micrometres apart (within the STEP file's
own declared precision) all projected onto the same surface point. The
boundary loop then repeated a point in (u, v), which a triangulator
can't follow, so the face's plan failed outright. One face without a
plan costs the whole body its plan, and the fallback mesher can't
handle a closed B-spline surface either, leaving both halves of the
split band with no triangles at all: present in the topology, invisible
in every renderer, and absent from the body's volume.
Fix: scale the off-surface tolerance to the body's own extent (new
Rules::extent), and collapse a run of boundary nodes that land on the same
surface point to one (drop_collapsed) before triangulating.
Regression test additions to band_faces_split_when_ring_edges_run_off_their_surface:
the body's volume now matches the analytic pentagon prism (was a third of
it - only the top cap - before this fix); display_plan leaves no face
without triangles from coarse to fine tolerance; and the actual tolerance
and facet angle the viewport draws with gives the split band its full
lateral area on both halves.
Confirmed on review_band_big.step, the fixture behind the review screenshots:
volume's relative error against the analytic pentagon prism drops from
1.4e-4 to 4.1e-6, and the band wall now occludes the floor grid behind it
in a snapshot the same way the top and bottom caps always did.
Full kernel suite: 739 tests, 0 failed.
* STEP import: hold an imported boundary to the file's own tolerance, not the part's size
jyviko: the off-surface acceptance added in the last commit
(rules.extent * OFF_SURFACE) scaled with the part, so a 2 m part
silently accepted a boundary 2 mm off its surface while a 20 mm copy
of the same part accepted only 0.02 mm. A STEP file's own declared
uncertainty does not grow with the part, so the bound shouldn't either.
Body gains boundary_tol: Option<f64>, Some(file's declared tolerance)
for a body read from STEP (crate::step_in::Units::tol, already used
by the ring-split fix in split.rs), None for anything this kernel
built. It's set before the import's own unmeshed-face check runs, and
carried over by the two face-split operations that re-cut an imported
surface (splitface.rs, outline.rs), since the file's uncertainty still
describes those boundaries afterward.
plan_face's accept now reads: the file's own tolerance when the body
declares one, or the old chord-tolerance/extent bound otherwise. The
old bound's tol * 10.0 term had to go too, not just the extent term:
at a 2 m part's typical display tolerance that term alone is ~20 mm,
nearly ten times the extent bound jyviko objected to, so keeping it
would have left the exact 2 m/2 mm example still silently accepted.
Two new tests in step_in/tests.rs:
- band_faces_split_when_a_scaled_copy_runs_off_its_surface: the same
band fixture at a realistic 2 m scale with the same absolute slop
and declared uncertainty as the small one, meshes the same way at
every chord tolerance from coarse to fine.
- off_surface_budget_follows_the_file_not_the_part_size: the actual
regression. The same off-surface error is accepted or refused the
same way whether the part is 20 mm or 2 m; a 2 mm error against a
1 µm declared uncertainty is refused at both sizes now (accepted at
2 m under the old bound, refused at 20 mm - that asymmetry was the
bug). Checked at both a coarse and a fine display tolerance.
Known gap, not fixed here: a STEP-imported body saved into a
.solidcraft design and reopened loses boundary_tol (native.rs's
decoder has no field to read it from) and falls back to the old
extent-based bound on reload. Today's design format has no concept of
this value at all; persisting it is a real format change, out of
scope for this fix.
Full kernel suite: 776 tests, 0 failed. clippy -D warnings clean.
* Display plans for STEP threads and pointed ends (#3847)
Three faces cost a threaded or pointed STEP part its whole display plan, so it
was drawn from the reference mesh: cracked, faceted, and never refined up close.
- A loop through a pole (a cone's apex on the boundary) seemed to wind around
the surface: the jump at the apex, unwrapped to the nearest copy, was
arbitrary. The loop is turned to end where it leaves the pole, so the step
that closes it is an ordinary one (`seam::close_through_pole`).
- Projection onto a spline with hundreds of spans (a helical flank) restarted
from a 16 x 16 grid and settled on another turn; it now starts from two
points per span, capped.
- Sag refinement no longer inserts a point exactly on a boundary side, which
split the side and failed the face.

A face whose boundary runs out and back along itself (two edges between the
same vertices, a rounding apart, as STEP files write slivers) encloses nothing
and is planned with no triangles. A face still refused after its edges are
divided finer (a cusp, a sliver whose sides sag across each other, a small cap
at a pole) is filled flat from its shared boundary nodes, so the rest of the
body keeps its display plan instead of falling back to the reference mesh.

* STEP import: a spline written over a tiny parameter range is read over one (#2814)
Some writers parameterize splines over a few millionths (a humanoid robot's
edges span 5.4e-6). The kernel tells parameters apart only to 1e-6, so over
such a range it evaluated the curve's end wrongly, and trimming an edge to its
vertices dropped a control point: the bodies could not be stored exactly and
the whole model cache was left out of the design. The knots are now stretched
to span one; the curve is the same and edges are trimmed by their vertices, so
nothing read from the file refers to the old parameters.

* model cache: a body keeps its file's declared accuracy (#2814)
A body restored from the cache dropped the accuracy the file it was read from

runtime values, and only when there is one.

* tess: a boundary within a hundredth of its body lies on its surface, at every quality (#2814)
#1721 held a body read from a file to the accuracy the file declares. A writer
declares what it aims for, not a bound its edges keep: a 251-body robot
assembly declaring 0.01 µm has boundaries 10 to 30 µm off their surfaces, and
95 of its bodies lost their display plans. The bound is a hundredth of the
body again, what Normal quality always allowed, and now the same at every
quality, so zooming in still never drops a face (#1721's point). A file
declaring more raises it.

* STEP import: keep faces whose edge vertices sit slightly off their curves
Some exporters write an edge's vertex beside the end of its curve, further off
than the accuracy the file declares (a surface export declares
0.01 mm and puts a vertex 0.19 mm off two spline ends). The reader refused
such edges and left the face, and with single-face bodies the body, out.
A vertex may now sit up to the file's tolerance or 1/1000 of the model's size
(the diagonal around its VERTEX_POINTs), whichever is larger, never more than
the existing 1 mm ceiling. Spline and open-conic edges have the end control
point moved onto the vertex, so every such edge meets its vertices exactly.
The file's declared accuracy still governs closed-curve, seam and circle
checks.
* tess, io: review clean-ups (#2814)
- A sliver face is one whose loops are all slit: drop_slits finds it in the
retry after a failed plan, so the pre-check on every face (folded) is gone.
- The flat fill uses cdt::triangulate (a lenient fill that leaves out sides
crossing one already kept) and its flood-fill inside test, and the plane
from geom::Plane.
- Refinement only builds its indexes when a face was refused, takes the
faces to plan again from edge_faces, and re-samples edges on the pool;
Rules::finer for the finer rules.
- One PackageWriter::fits for the model cache, the preview and the thumbnail.
- The band split's ring tolerance lives in split.rs; comments say what the
off-surface bound is now.
- The CLI logger prints Level::as_str().

Save As and Open use the browser's file dialogs where the File System Access API exists; Save writes back to the same file, its handle kept in IndexedDB across reloads. File > Download design added. Other browsers keep storing designs in OPFS.
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.

BIZ UDPGothic's Cyrillic glyphs are full-width (1.0 em), so promoting the
CJK font to the front of Proportional made Ukrainian text look wide with
large gaps between letters, broke word wrapping, and truncated UI labels.
When CJK text loaded on the web, install_cjk_font hard-coded "ja" and
stayed promoted after switching to Ukrainian or English.
Pass the live UI language to install_cjk_font_for so the CJK face only
leads a CJK UI. Keep fetched CJK font bytes on the web shell and re-apply
fonts when the language changes, and add a regression test that a
non-CJK UI keeps the CJK face as the last fallback.
* Spike: typed parameter contracts and JSON Schemas for solid.box and solid.extrude
The schema RFC's spike (plan/schema-spike.md). solid.box and solid.extrude get
typed contracts with generated JSON Schemas (2020-12), checked in front of the
unchanged handlers by a per-session level: off (the default, which changes
nothing), warn (the call runs and gains param_warnings) or strict (the call is
refused and the design left alone). Also engine.describe and the MCP tool
describe_command, `solidcraft-cli mcp --param-check off|warn|strict`, a
FeatureResult type for feature replies, and an env-var audit recorder
(SOLIDCRAFT_PARAM_AUDIT) used to check the contracts against every test.
Local spike branch; not for upstream as is (see the results report).

* Parameter contracts: put the audit recorder behind a feature; drop two ignored test keys
The audit recorder is now on only in a build with the engine's `param-audit` feature
and `SOLIDCRAFT_PARAM_AUDIT` set. Its code is still compiled, linted and tested without
the feature. `scripts/param_audit.py` summarises a test run's audit logs, and the schema
module's docs give the steps for converting a further command.
Two tests passed keys their command ignores, which the audit found: `position` on
`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
the contracts a spike.

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

* Snapshot: draw a see-through appearance see-through, and give the CLI --body, --tool and --section
A headless picture dropped a body's opacity: the scene carried only a colour, so a design with
a translucent appearance was drawn opaque by `solidcraft-cli snapshot`, by MCP screenshots and
in a design's thumbnail, although the window has always drawn it as glass. There was then no
way to look at the body a cut would remove inside the material it meets: only a volume to
measure and reason about, which hides exactly the errors a picture makes obvious (a tool that
stops short, or lands in the wrong place).
- `SceneMesh` carries the body's opacity; `view::build_scene` takes it from the design
(`model_body_opacity`), and a selected body stays solid so the selection colour reads.
- The GPU capture routes a see-through body into the scene's glass at its own alpha, as the
viewport does; the CPU rasterizer draws the solid bodies first (they own the depth buffer),
then the see-through ones blended over them, far sides before near sides and without writing
depth, so what lies inside shows and a line between the two is not hidden.
- `snapshot --body NAME:opacity=0.3,color=#rrggbb`, `--tool NAME` (that body solid in the tool
colour, the rest see-through) and `--section z=27` run the commands the app itself runs
(`appearance.assign`, `inspect.section`): the options are shortcuts, not a second renderer.

* Tests: measure the tool colour as it is drawn through a see-through target
The tool-colour filter was derived on paper and demanded a red more than twice either other
channel, which the target in front of it tints away (measured: (200, 108, 85) through opacity
0.3); and the colour check painted the tool, which a solid target hides.

* fmt
* Snapshot options: strip the colour's # rather than slicing it; README
Slicing `value[1..]` on an input-derived string is what the house rules ask us not to write,
even where a length check has already made it safe. The error a failed assignment reports now
names the body rather than claiming it came from --body, since --tool reaches it too.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* --tool: assign the bodies around the tool in groups, not one command at a time
Each appearance.assign is an undo step with a document snapshot behind it, so one per body
made --tool cost grow with the size of the design for no reason: the bodies around the tool
all get the same opacity, and the ones that share a colour can be named in one call. A design
whose bodies all wear the default grey now costs two commands whatever its size.

* Rasterizer: say where its glass and the GPU's differ
Splitting each see-through body by facing orders its own two layers; it does not sort across

The kernel will move from truck to solidcore (#1597). The tests that must
catch regressions across that switch are the ones that don't depend on the
kernel: the reference tests and the robustness goldens. cargo-mutants checks
whether they would notice a change in the kernel's behaviour.
- apps/solidcraft-cli/tests/oracle_cases.rs: the reference tests as a cargo
test (ignored; CI keeps replaying them through cargo xtask oracle), run
over one process per core.
- .cargo/mutants.toml: mutants are judged by that test and the pull-request
sample of the robustness goldens, not by the kernel's own unit tests.
- A mutants profile (ci with incremental builds): about 15 s to rebuild after
a kernel change instead of about 3 minutes.
- docs/mutation-testing.md: how to run it, its cost, two cargo-mutants 27.1
problems and the pilot's results (15% of sampled kernel mutants caught).

BSplineSurface::uuder and vvder multiplied the second differences by p

1/(p − 1) of its second derivative: a cubic surface's curvature read as
half. This is why a G2 boundary surface on a cylinder measured half the
curvature it carries (#763). New tests hold both to finite differences
for degrees 2 to 5.

* test(kernel): a boundary patch with straight corners measures its own area
A stadium's arcs meet its lines at 180°, so the Coons patch is singular
at its corners. From such a corner the reference mesher's boundary walk
ran onto the B-spline's extrapolation past its domain (a planar spline
passes through every point of its plane there), and the face measured
289 mm² for its 158.5 (#763). The vendored mesher's bounded projection
(nearest_projection, #2043) keeps the walk on the domain; this holds it
there, by the faces, the measuring mesh and the display mesh. The
display path (#1653) was never affected.

* feat(geom,kernel): three-sided boundary surfaces (one side collapsed to a point)
A network curve may be a PointCurve: the apex where the two sides beside
it meet. The curves through it cross it at the point itself, its row of
the net collapses there, and the kernel's face leaves that side out of
its loop (three edges, one vertex at the apex). One point per patch, as
a side; refused elsewhere, when it moves, or with a continuity
condition. Tests: a triangle and a quarter disc filled flat with their
analytic areas (40 mm², 25π), by geom and by the kernel's faces and
meshes.

* feat(doc): boundary surfaces through curve networks and loops of three or four
FeatureKind::SurfaceNetwork saves a network as `u` and `v` curves, each
a sketch chain (planar or 3D), a chain of a body's edges with an
optional G1/G2 continuity, or a point (the apex of a three-sided
patch), and an `operation` that can join the surface into the body of
its edges. A SurfaceBoundary of three or four sketch curves, refused
until now, builds as the flat Coons patch of its loop (three collapse
the side opposite the first curve). The format change is one pending
file; feature-walk goldens record the new variant's sketches, bodies
and points.

* feat(engine): surface.boundary through loops of three or four and curve networks
The command keeps its loop form (two to four curves of one sketch; three
and four now build the flat patch of the loop, crown refused there) and
gains a network form: `u` and `v`, each curve a sketch curve id, a
{sketch?, curves} chain (planar or 3D), a {body, edges, continuity?}
edge chain (g1/g2 with the face beside it) or a {point} for a
three-sided patch, with `operation` new or join. Edits may move between
the two forms (timeline.redefine accepts the command now that it has a
dialog).
Tests: analytic areas of loop patches and of a hyperbolic paraboloid
bounded by four 3D lines (every mesh vertex on z = xy/10), a loft
across two sketches, G1 and G2 measured across a cylinder's edge with
inspect.continuity (angle < 0.1°; curvature jump 1e-16 with G2 against
0.027 with G1), 26 hostile networks refused without panicking, and u/v
added to hostile_params_never_panic.

* feat(ui): Boundary Surface dialog
Curves and Cross curves take sketch curves and edges (picks that meet
end to end in one sketch or body are one chain); Continuity and
Operation (New Body or Join). Two to four sketch curves of one sketch
with nothing across are the loop patch; anything else is a network.
Edit Feature brings either back (per-side orders, crown and stations
the dialog does not show are kept). Strings in en, ja and zh.

* test(oracle): a boundary surface through a loop, thickened (#763)
Case 83: four sketch curves (a square's three sides and a half circle
for its top) make one boundary surface, thickened 2 mm; analytic values
from tools/oracle-analytic/cases_surfaces.py (V = 2A, area 2A + 2P,
centroid by moments). Recipes gain boundary_surface, thicken and remove.

* refactor: boundary surfaces, review cleanups
Project onto the face once per derivative evaluation (the frame is
passed to natural() and reused by scale()), keep each track's
finite-difference step instead of rescanning its table, export the
kernel's edge-pick and chain caps and the default station count for
the engine, doc and dialog to share, map TooLarge spline errors to
KernelError::TooLarge, reuse the engine's operation parser, and skip
the dialog's sketch lookup when the picks are no loop.

* claim: #1801
* Insert SVG: the file picker opens on SVG files (#1801)
Every Open went through one host picker whose filters start with designs, CAD
files and meshes, so Insert SVG (and Insert DXF) in a sketch opened on STEP,
IGES and meshes, and the SVG file had to be found under another filter.
The host's pick_open now takes the extensions the command reads and offers
them as the picker's first, default filter. Insert SVG and Insert DXF pass
their type; every other Open passes none and keeps the list it had. The
browser host ignores them (it shows its own file panel).

SolidCraft read the HID device directly, which bypasses spacenavd and
everything set in spnavcfg (swapped and inverted axes, sensitivity, dead
zones). When the daemon's socket is there it is read instead, with a fixed
32-byte record decoder and no library; without it the hidraw path is
unchanged. The daemon sends a record only when values change, so its
readings are held until the next one rather than going stale.

FreeCAD .FCStd and Rhino .3dm files open, insert and drop like STEP and IGES:
cadmpeg (Apache-2.0, pinned =0.6.1, native builds only) detects the format,
decodes it under its service resource caps, validates the model and writes it
as STEP AP214, which becomes an Import feature in a new component named after
the file, with the up and names options.
Only the fcstd, rhino and step codecs are compiled in (no default features).
ACIS is left out: cadmpeg's sat codec is a ShapeManager stream decoder.
native_cad.rs is the single importer seam. Self-made FreeCAD and Rhino box
fixtures, hostile-input, ZIP-bomb and cap tests, engine tests for the
component path; the browser build reports these formats as not supported.
A note under design format 23 says an Import's file can name these formats.
