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.

glTF files open, insert and drop like 3MF/STL/OBJ: a component named after the file, the node tree as nested rigid components, repeated meshes as occurrences, metres to mm, Y up turned to Z up by default (up: z keeps axes), materials as PBR appearances. Bounded, hostile-input tested reader; no new persisted data. Closes#1505.

* Imports become components: a STEP assembly's tree as nested components (#1386)
Every imported file (STEP, IGES, 3MF, STL, OBJ: inserted, dropped, opened as a
design, or file.insert_step / file.insert_mesh / doc.open from scripts, the CLI
and MCP) now comes in as a new component named after the file, with its Import
feature inside it. A STEP assembly's products become nested components; a part
placed more than once is one component with an occurrence per placement, and
the Import feature skips the file's later copies (`skip`, format 21 note). The
contents are held as one rigid group (rigid joints, glyphs hidden); moving an
inner part is refused until component.unlock ("Unlock Contents") releases it.
Y up turns the import's component. Replies report component, component_name
and occurrence. Undo is one step; designs with loose imports are unchanged.

Part of #771 and #772. solid.sweep and surface.sweep take orientation (perpendicular, parallel or a direction), twist (up to 4 turns) and end scale (0.01 to 100), applied about the profile's normal through the path's start; default options run the old sweep, so existing sweeps are unchanged. New fields are optional, left out when unset and noted under format 21; twist and scale are model parameters. Both sweep dialogs get Orientation, Twist and End Scale rows; labels in every catalog. Checked on main + this branch: cargo check --workspace, kernel/engine/UI sweep tests, the doc suite and the robustness goldens.
file.insert_step and doc.open on a STEP file take `up` (turn a Y-up file so its up is +Z) and `names` (names for the imported bodies). The MCP tool and the app's control requests pass them through; an import without them works as before. Tests in the kernel's STEP reader, the engine, MCP and the file-load UI; docs/step-import.md and docs/mcp.md describe both.
snapshot starts from --in (a design or STEP file) with the script on top, as run does, and refuses options it doesn't take; an unknown command id names the closest registered ids.
A round or chamfer whose edge chain runs on across a curved seam (the end circle of a lofted tube whose axis bends) is now built: the section solve keeps its contact on the seam through a plane taken afresh at the seam's nearest point at each step. Straight seams are unchanged. Robustness seed 41 is re-recorded: its second fillet, refused before, now builds. Fixes#1213.

A loft section with a hole is refused with a clear message instead of being lofted as if filled, in both section-to-section and section-to-point lofts. Fixes#1184.
* Smart Extrude: direction from the picked side, Cut into a body stays a Cut (#1257)
- A sketch profile (or a thin extrude's curve) extrudes toward the side it was
picked from: from the bottom view it goes down. Body faces still go outward.
- The automatic operation is latched per side of the profile: a drag that starts
into a body is a Cut and stays one past the far side; a Join does not become a
Cut when it reaches another body. Passing through zero decides afresh for the
new side.
- An explicit operation, Direction or Reverse ends the automatic choices.
- auto_operation also looks just past the profile, so a long cut through a body
reads as a Cut from the start (the engine's operation: "auto" too).

When projecting a face's boundary loop onto its surface fails from an unhinted first point, the walk is retried once from the first point an unhinted search does find; a walk that succeeds is unchanged. A fillet strip on an extended surface now meshes, so the rim cut in the reported case builds in one boolean.

Thin Extrude builds walls of a set thickness along sketch curves, open chains and closed loops, with the wall centred, inside, outside or on both sides at two thicknesses. Saved under format 20 (thin on an Extrude); an extrude without thin saves as before. Closes#721.
Bodies imported with the same label come in as X, X (2), X (3). Renaming one of them no longer renumbers the others: body.rename now pins the current names of the feature's other bodies when it stores the new one, so later renames, materials, appearances and features still find them.
timeline.export_script (and solidcraft-cli script) writes a design's history as a command script that solidcraft-cli eval replays into the same design, so a bug that only shows on one design becomes a one-file repro. timeline.add restores one stored feature with its id, names and references, through the same checks a design file gets when it opens.
Closes#886. SychPL's #1078 approached the same issue independently; thanks to both.

Cutting one lofted round tube from another failed in truck's divide_face ("parameter boundary") for some section counts: the intersection points lie on the loft's seam, the previous point's parameter can sit a hair outside the range, and the Newton search from there fails.
The boundary is built as before; only when that returns None is it built again leniently, starting each search from the hint clamped into the parameter range and, as a last resort, searching the whole surface. Nothing that succeeds today changes. The boolean-retry guards are untouched.
Fixes 5 of the 6 failing hollow-elbow cases in #968 (new test crates/engine/src/tests/loft_cut.rs, volumes within 0.3% of exact). 90 degrees / 14 sections still fails in a later step and stays open in #968.
Walls swept along a spline have flat B-spline tops and bottoms, so booleans between them went to the general intersection, which fails on coincident spline faces. Such faces are now put on true planes, and two prisms of the same height and direction are decided in 2D with their spline outlines fitted by arcs within a micron. The result is kept only when its volume is plausible; otherwise the general boolean takes over. The free-form flag is cleared by a drop guard so an unwinding boolean can't leave it set.
Fixes#844.
Body::with_planar_sources compared every planar face of a result with every unsourced planar face of its inputs, so a boolean on an import with a few thousand facets ran out of its comparison budget before it started. The lists are now sorted by normal x and each face only compares with entries inside a narrow normal window found by binary search; the exact same_support test and the work budget are unchanged. Adds an engine test joining a pin onto a 4000-sided imported prism.
find_close_pair's budget now counts the grid's own work too (each cell a triangle is filed under or visits), not only the pair tests, so a pathological pair of meshes can't spend unbounded time building and walking the grid. Adds tests for find_close_pair and the budget.
Agent tool calls (MCP, and bridged control requests carrying allow_paths) reach files only in the open design's folder (strictly inside home or the temporary folder, not in a hidden folder, and never its hidden files), the app's recovery folder, the server's private scratch folder and each --allow-path; --allow-any-path lifts the limit. Paths are resolved first, so .. and symlinks that lead out (including a save through a link, #845) are refused. On Windows, UNC, device, NT, verbatim non-drive, drive-relative, alternate-stream, reserved-device and 8.3 short-name paths are refused before any file system call, and the resolved path must be on a local drive. doc.recovery_discard and doc.recover {discard} delete only real recovery entries. Docs: mcp.md, control-protocol.md, README.
tests/robustness/goldens.json records what each of seeds 0-95 builds: its steps, how it ended (ok, or the kind and the start of the error it was refused with) and, for the design it left, the bodies' total volume and area (within a relative 1e-6) and their face, edge and shell counts. tests::robustness_goldens fails on any change; ROBUSTNESS_GOLDENS_BLESS="why" records one, with the reason and the seeds it moved. Pull requests that touch crates/kernel run every 8th seed; pushes to main and the nightly run every seed.

Adds `fit: taper` to Fillet: where a constant radius doesn't fit along a straight edge, it follows the room there as a smooth spline, down to zero where a face closes to a point. Taper to Fit is in the Fillet dialog, and the feature's warning says how far it tapered.
Extrude and Revolve from a body face take `face_body` to say whose face is meant where faces of several bodies meet flush at the picked point. Without it, an ambiguous pick now names the bodies that meet there instead of saying there is no face. Fixes#703.

Fillet fit: reduce lowers the radius only where it doesn't fit: picked edges are grouped where they can limit each other (sharing a face or vertex), and each group gets the requested radius where it fits, otherwise the largest that does. Refs #293.

A flat face that no construction certificate names on its own now attaches by its exact history name (a new lineage face certificate): cut walls and floors, chamfer faces, each pattern or mirror copy, side walls a Join merged, and the pieces a later feature split a face into. Construction certificates still come first; a seed keeps its certificate when it is patterned. Two flush extrudes of one outline joined end to end keep their exact history in the prism boolean. Face sketch 52% -> 71%, offset plane 52% -> 71%, press-pull/extrude from face 41% -> 60% in the action matrix; baseline blessed.

MCP batch takes verbose: false for compact replies: feature steps leave out the full body list and sketch steps the ids they repeat outside created. Feature replies now also list changed_bodies and removed_bodies next to created_bodies, so a compact reply still shows every effect of a step. Un-ignores the #530 regression test. Fixes#530.

Tapered extrudes accept profiles that mix lines and tangent arcs (slots, D-profiles, rounded rectangles): each arc keeps its centre and angles and its radius moves with the taper, so its side stays an exact cone; lines are offset and mitred. An arc meeting another edge at a corner is still refused. Un-ignores the #546 regression test. Fixes#546.

Draft extends the picked faces to every face on the same surface, so one pick on a cylinder's side (stored as two halves) drafts the whole round wall into a frustum. Un-ignores the #547 regression test and adds a kernel test for a round hole. Fixes#547.

A copy added by raising a body pattern's count after a rename is numbered after the highest stored copy, so it no longer takes the number the rename freed. Un-ignores the #372 regression test and adds one for undo/redo and save/reopen. Fixes#372.

Fixes#374. Feature replies gain created_bodies: the bodies the new feature made, apart from the ones it changed or that were already there. Documented in the execute tool description and docs/mcp.md.
When a body that was already cut into pieces is cut again, the new pieces are numbered past the names already taken ("Bar (2)"), instead of reusing "Bar (1)".

When adjacent profiles are merged for one extrude, collinear lines on either side of where a shared boundary ended are joined back into one edge, so the body has no split faces or extra vertices for later booleans to trip on.

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.

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.

* 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.
