The old ids live only in crates/engine/src/legacy_ids.rs (the legacy migration table): find_command maps them, so old scripts, recipes and control calls keep working, and saved shortcuts, recent and pinned commands are migrated on load (designs store no command ids). Parity maps the observed catalog ids to ours through xtask/data/fusion-ids.tsv. The agent rule now reads: our own dotted id, never another product's. Cargo.toml's repository points at github.com/bherbruck/solvecraft.

blend_corner.rs rebuilds the planar faces at the ends of the filleted edges (three planar faces and three straight edges at each such vertex) and keeps the rest. One round at a vertex ends in the third face's exact section of its cylinder; two rounds with the third edge sharp trim each other (rolling ball: the crease from where their contact lines cross to the third edge for equal radii, else to the smaller round's contact line on the face that ends the larger one, which gets the exact section between); three rounds meet a sphere for equal radii, else a rational degree-4 patch through plane sections of the cylinders, the sections turned so that the cylinders' curvatures agree where two meet on a face and the patch fitted tangent to all three (within 0.01 degrees) and to the face at its closed corner.
kernel::fillet falls back to it when the local blends refuse: an edge that ends on an earlier round (any radius) takes the round off (delete_faces) and blends both edges together, so r3 next to r2 and a third edge into a mitred pair work. delete_faces: a gap stretch along several deleted faces keeps the corners between them (two rounds meeting in a mitre come off back to the sharp corner). splitface::fit is shared for the crease.
Tests: volumes against the strips-minus-overlap reference (exact strips, overlap integrated; checked against an independent 1D integral), the sphere-octant formula for three equal rounds, tangency along the patch, closed meshes, refusals without panics.

New kernel file blend_variable.rs. The hooks into blend.rs are visibility
only: plane_normal, vtx, rebuild_face and unsupported are now pub(crate).
- fillet_variable(body, edge, start, r0, r1) works on the same edge
configuration as the constant fillet (straight edge, planar faces, end
faces square to it). The radius runs linearly from the end nearest
`start`, and every section square to the edge is a circular arc. The
blend is an exact degree (2, 1) rational B-spline: arc control points
move linearly.
- fillet_chord(body, edges, chord): the radius per edge comes from its
face angle (chord = 2 r cos(phi/2)).
Fillet feature: style constant | chord | variable {radius2, start};
FusionFilletEdgesCommand takes type, radius2 and start.
Tests:
- Variable 2 -> 5 on a box edge removes (1 - pi/4) L (r0^2 + r0 r1 + r1^2)/3.
Starting from the other end gives the same solid; equal radii give the
constant fillet; too large is refused.
- Chord 4 on a right angle equals radius 4/sqrt(2).
- Engine: both types by command.

- solvecraft_io::vfs: the engine's file access (disk natively; in the browser an in-memory set of
files the host loads and stores). File commands and write_atomic go through it.
- Web host (apps/solvecraft-web/src/files.rs): stored designs are read from OPFS at start
(storage.persist() asked for) and written back when a command writes one; Save/Save As keep
designs in the browser, exports (STEP, STL, 3MF, OBJ, ...) download as files.
- File > Open shows "Files in this browser": open, insert, rename, download, delete, plus open or
insert from the computer (showOpenFilePicker where there is one, an <input type=file>
otherwise). Files dropped on the page are inserted or opened.
- Unsaved work is autosaved to OPFS and offered again after a reload or crash.
- Start page recents come from the stored designs, with thumbnails. In the browser the samples
are built when opened (a picture blocks the page there, and a kernel panic can't be caught).
- Pages without OPFS (http on a network address, old browsers) keep designs in local storage.

For solvecraft-params' Split Face feature:
- Sketch tools are chains of Seg2. A single line splits by its plane and a
single arc by its cylinder, exactly (a circular edge on a planar face);
longer chains and splines follow the curve.
- split_faces_with_map gives the source face of each face of the result.
- A listed face the tool misses is an error naming it (split_any keeps
the lenient form for Trim).

Three step_in tests and two split tests failed in debug builds only:
truck's debug_new asserts simple loops and two distinct end vertices, but
faces whose loop runs a seam edge both ways and full-circle edges on one
vertex are valid. Meshed faces and edges are now built unchecked. ci
(release) was unaffected; the kernel tests pass in debug and release.

The standard parts library by type (with its ISO standard), size and length, the size's table
values and a picture of the part; picking a hole's wall or rim seats it there with a rigid joint
(the live preview shows it seated), without a pick it goes at the origin. Opens on
FusionFastenersCommand (and parts.insert); OK runs FusionFastenersCommand. Its own icon.
Insert's world picks (`at`, `point`, `direction`) go through the component frames like other
picks. Tests for the library parsing and the insert parameters; checked in the app: an M3 socket
head cap screw seated in a drilled hole with its joint.

Kernel extend(body, edges, distance) moves the picked straight edges of a
planar surface outward in its plane, with neighbours meeting them. Doc
feature SurfaceExtend, engine FusionExtendCommand. Tests: 10x10 extended
by 5 past one edge gives 150, past two gives 225; the engine patch, trim,
extend and thicken gives 240.

Kernel (surfaces):
- Bodies with an open shell are surface bodies (Body::is_surface).
- patch_region: a planar patch of a sketch region. patch_edges: a planar
patch filling a closed loop of a body's edges.
- copy_faces: faces copied out as a surface.
- stitch: sew surfaces along coinciding edges, turning faces to agree; the
result is a solid when it closes.
- trim: cut a surface by a plane or face and keep one side.
- thicken: offset planar and circular-cylindrical faces along their
normals (one side or symmetric) into a solid. Plane copies slide;
cylinder copies scale about the axis, exact for NURBS circles. Free
edges get ruled walls. Faces meeting at a sharp edge are refused.
Doc features Patch, Stitch, Thicken (with operations) and SurfaceTrim;
engine commands FusionSurfacePatchCommand, FusionSurfaceStitchCommand,
FusionSurfaceThickenCommand and FusionSurfaceTrimCommand.
Tests (volumes):
- A 10x10 patch thickened by 2 gives 200, also symmetric.
- Half a cylinder side thickened outward gives half a ring; both halves
inward give the full ring.
- Six faces of a box stitched back give 6000; an open box with its top
patched from the edges, stitched, gives 6000.
- Trim keeps 30 or 70 of 100.
- Engine: patch, trim, thicken gives 140.

The Split feature takes an optional face tool (FaceAt, the face through a
point on a named body) and splits with kernel split_body, the tool's
surface extended; otherwise the plane as before. Engine test: a box split
by a cylinder's side into the core and the rest.

split_body(body, tool) divides every face where the tool meets it and
closes each side with the piece of the tool surface inside the body.
- Patches have outer loops and holes.
- Bands go round a cylinder or another surface of revolution.
- Each side falls apart into its connected parts.
- A body the tool misses comes back whole.
Faces that are B-spline sheets but really planes or circular cylinders
(extruded faces) split as the whole plane or cylinder: the tool is
extended, and the field is exact and cheap.
Tests (volumes): a box split by a plane (2400/3600); a holed plate split
through its hole into two equal halves; a box split by a cylinder's side
into the core (pi*16*30) and the rest; a plane that misses.

split_faces(body, faces, tool) divides the chosen faces where the tool
meets them and leaves the solid unchanged. It handles:
- lines across a face;
- closed lines inside a face (a disc inside a ring);
- lines that run into a hole (the face is divided around it).
Edges the line ends on are cut in every face that uses them. The tool's
zero set is traced on a finely divided triangulation of the face, each
point is placed exactly on the surface by bisection in its parameters,
the ends are placed exactly on the boundary edges, and a cubic is fitted
through the points (a line when they are straight).
Tests: a box top split by a plane (areas 80/120, later booleans still
work); a cylinder side split by a sketch line; a cylinder top split in
ring and disc by a smaller cylinder's face; a plate top split through
its hole into two equal halves; a tool that misses is an error. Volume
and area are unchanged in every case.

- IGES import (kernel iges_in, from the published specification). The file
is restated as STEP and read by the STEP reader, so an IGES file becomes
the same Import base feature.
- Manifold solid B-reps (186/514/510/508/504/502).
- Trimmed (144), bounded (143) and bare B-spline surfaces, sewn into a
solid by shared edges, with face orientation made consistent.
- Curves: lines, arcs, ellipses, composite and rational B-spline curves.
- Surfaces: planes, analytic surfaces 190-198, B-spline surfaces,
surfaces of revolution and tabulated cylinders.
- Transformations, units, colours, names (406 form 15 or labels).
Open, insert and drop .igs/.iges like STEP.
- IGES export (kernel iges_out): each body as a manifold solid B-rep on the
surfaces a STEP export uses, with name properties and colours.
ExportCommand to .igs.
- OBJ import as mesh bodies: objects/groups, polygons fanned, negative
indices, bad lines reported.
- STL: binary files whose header starts with "solid" and those with a zero
triangle count read as binary; non-finite vertices dropped; facet
normals ignored; ASCII with non-UTF-8 names. Mesh bodies get consistent
winding (stray inverted facets turned over).
- Tests: primitives and features round-trip through IGES (volume, area,
name, colour). Six trimmed patches sew into a closed box. Hostile IGES,
OBJ and STL inputs never panic. STL quirks. The engine exports a design
to IGES and opens it again. All 76 oracle parts round-trip through IGES
with matching volume (local check).

What a component holds moves with its occurrence, and picks in the world land in the
component's frame:
- Sketches and construction planes show where their component is placed (free move, joint
drive, Capture Position); sketch.inspect reports sketch points in the world.
- frames.rs maps a command's world picks into the frame of the body they lie on (through the
inverse of its placement: a moved component or a pasted instance), points that make new
geometry into the active component's frame, and directions with them; instance body names
("Body1 (Pin:2)") become the component's body. Fillet/chamfer edges, shell/offset/draft
faces, face extrude/revolve, sketch on face, holes, sheet metal and plastic picks, primitives,
appearance faces, analyses. Once per command (not again for commands run by commands); the
active-frame fallback stays for commands without a table. Nothing changes while every
placement is the identity.
- component.move_bodies keeps a body where it is in the world (Document.body_offsets: from the
new component's frame to the one it was made in; renames and deleted components follow).
- The UI reads the placed model (Session::world_state) for display, picking, sketch editing and
dialogs; live previews use it once anything is placed.
Tests (engine): sketches and construction planes move (and turn) with the component; world
picks fillet, sketch, hole and make boxes in a moved component; a pick on a pasted instance;
move_bodies keeps the world place there and back; a sketch on a face follows a Move feature.
QA's s34 now runs.

The read-back check (fallback to unmerged pieces) imported every export.
Now it runs only when some body actually had faces merged. Oracle 41
(42 faces, nothing merged): export no longer re-imports, which saved 7 s.
Pipe flange (merges): 1.1 s for the read-back.
