* Fillet: refuse a result with openings in its surface (#871)
A fillet on #871's part (radius 1 on a window's edges and on the sides of a
block 1.26 mm away) came back closed as topology with every face meshing, but
the rounds overlapped and the end faces' boundary loops crossed, so the model
showed holes. The constant-radius fillet now checks its result before taking it:
the body's mesh, welded within a millionth of its size, must have no edge
without as many triangles running the other way along it, except for cracks
within the mesh tolerance where fitted curves meet. A result that fails is
refused, so the corner build gets its try and the radius search treats it as
too large.
Body::open_mesh_edges is the check. Kernel tests cover the #871 part (refused
at radius 1, closed with a round on every edge at 0.5), and an engine test runs
the fillet from the report and leaves the part as it was. All 96 robustness
seeds build the same with and without it.
Fixes#871

* Check fillets for crossed face boundaries, not free mesh edges
Free edges in the mesh also come from cracks where fitted curves meet (corner
patches, rounds ending on curved edges), so the mesh test refused good fillets.
The check is now on the cause of #871: a planar face whose boundary loops cross
each other or themselves has no inside. Body::crossed_face_loops samples each
planar face's loops within 1/1000 of the size and counts proper crossings
(touching within a millionth doesn't count).
The pyramid apex blend and the loft fillets build again. Ten action-matrix fillets
stay refused, recorded in the baseline: r = 3 on the 2 mm rim of oracle 09's
shelled box (the round runs past the inner wall; the result was 240 mm3 lighter
than any round can make it), and the six seam-edge fillets on oracle 60's bolt
holes, whose boundary jumps across the hole.

- A fold's zone clipped across the root of a tab folded before on the same
line kept a sliver of no width there, which made the zone look like it
crossed a slanted edge. The one real piece is the zone now (#638).
- When the tabs a fold line spans can't take the side beyond them along,
because it joins the side that stays through other material (a tab on the
inside edge of an L, the fixed point on the far leg), the tabs' own ends fold
instead, the same part as with the fixed point on the near leg (#639).

* Name a side drawn on several sketch curves by all of them
An extrude named each side wall after the one sketch curve its profile
segment lies on. A wall along two coincident lines (squares drawn edge to
edge) or along collinear lines merged into one profile segment had no
single curve, so it was named from geometry and could not carry a sketch
attachment. One sketch extruded up and down and joined (the logo) refused
a sketch on every one of its side walls.
Such a side is now named by every curve it lies on, in sketch order: the
first is its name, the others aliases. The set is fixed by the sketch, so
the name is exact. The refusal message no longer blames merged faces.
Adds the reported logo design and a synthetic up-and-down join to the
action-matrix designs, and a regression test that sketches and extrudes on
every flat face, fresh and after save and reopen.

- A new cut was clipped against the panel with every one of its cut-outs, so
each hole of a perforation cost the square of all the holes before it and the
second cut of 500 ran out of the flat budget. A tool is now clipped against
only the cut-outs whose boxes meet its own (the same result).
- The planar booleans' point-in-loop test now skips loops whose box is clear of
the point, before the costly on-the-loop test; with a thousand holes that test
was most of the time.
The 1000-hole panel now takes about 15 s instead of failing.

On a large thin sheet the probes around the fixed point stepped clean through
the sheet (twice the mesh tolerance of a 465 mm part is more than its 0.8 mm
thickness), so a point exactly on the face touched no material and the fold
was refused. The probes now also step a quarter of the thickness.

* Rounded Rectangle sketch tool (#891)
A new SKETCH > CREATE command, sketch.rectangle.rounded, in the Rectangle
family: two opposite corners and a corner radius make a 2-point rectangle
whose four corners are filleted alike, as one undo step. The radius is one
parameter (one radius dimension, the other arcs equal to it), so changing it
changes all four corners. While drawing, Width, Height and Radius boxes take
typed values; typed width and height dimension the overall size between
opposite sides. Without a typed radius the corners get a fifth of the shorter
side.

Session::replace_design keeps auto_project when file.new, doc.open and doc.recover swap in another design, and the UI keeps it across tabs, adopt and the last-tab close. Regression tests in engine (sketch_project) and ui-egui (documents).
Rolling-ball blends now handle knife edges, where the two faces have opposite normals; an edge that runs out along an end face tangent to one side; and rounds that end in an earlier round on curved faces, picked together or one after another. The three edges at a vertex of smooth faces, rounded to one radius, end in a piece of sphere. When the given order of up to four edges is refused, or leaves a face boundary off its surface, other orders are tried.
Closes#851.

Offsets picked faces along their normals into a new surface body: planes and cylinders move exactly, other faces get a fitted B-spline within tolerance, and offsets that would fold over are refused. Adds the SurfaceOffset feature (noted under format 18), the surface.offset engine command and an Offset Surface dialog.

A design with components and joints exports as a URDF robot description (file.export to .urdf, the MCP export tool, solidcraft-cli run --out, File > Export URDF...). It writes one binary STL per component in metres, links with mass, centre of mass and inertia from material density, and maps rigid, revolute, slider, cylindrical, pin-slot, planar and ball joints to URDF joints or short chains. Loops, broken joints and loose parts are reported as warnings. Options: mesh_prefix, effort, velocity. Docs in docs/urdf.md.
Each wall of a surface built from sketch curves (Surface Extrude, Revolve, Sweep and Loft) is now named after the curve it comes from, exactly rather than from geometry, so references to those faces survive edits.
Surface Loft lofts open or closed curve chains, one section per sketch in pick order, into surface bodies. Adds the SurfaceLoft feature (format 18 note), the surface.loft command, a dialog with Edit Feature support, and kernel and engine tests.
Part of #757.
#825 chose the faces to split by boxing each face, dividing its curved edges down to the contact tolerance; on the sensor enclosure's lid that division never finished (press/pull and extrude on 18 faces grew past 24 GB and timed out in the action matrix, on CI as here). The boxes now come from the edges' control points, with no division; a face whose extent can't be found counts as near. A test holds the lid's press/pull to a time budget.

Surface Sweep carries open curves and closed profile boundaries along a sketch path into surface bodies, with smooth walls along curved point paths. Adds the SurfaceSweep feature (format 18 note), the surface.sweep command, a dialog with Edit Feature support, and kernel and engine tests.
Part of #757.
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.
Surface Revolve turns open curves and closed profile boundaries about a sketch axis into surface bodies, with cone apexes and sphere poles where a chain ends on the axis, and a closed shell made solid. Adds the SurfaceRevolve feature (format 18 note), the surface.revolve command, a dialog with Edit Feature support and analytic kernel and engine tests.
Part of #757.
A lip picked on a face that isn't a shelled body's rim, such as the Sample Plate's top
face with its two holes and the boss standing on it, ran its band round the largest inner
edge. That was the boss's foot, so the band stood against the boss's wall and the join
failed with a boolean error about curved faces.
The band now goes round the face's opening (an inner edge with no material just over the
face inside it). A rim face that has a smaller hole in it still works. A face whose inner
edges are only where other features stand on it, or whose openings are alike in size (a
plate's holes), is refused with a plain message that names the rim face it needs.
Fixes#892.

Generates N parts of four primitive bodies, each moved into a placed component. The test (12 parts) checks the open, the world placement and the saved round trip; the ignored bench_generated_assembly prints parse, evaluation inside and outside the features, mesh warm-up and Measure.
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.
Hole centres from a sketch now drill into the material on whichever side of the sketch plane it lies: material the spot starts in wins, then the nearest body ahead, else against the sketch normal as before. A sketch on a part's underside or below it now drills up into the part. Covers counterbores, through-all, edge and corner centres, patterns and reopening.
Delete Face takes heal (default true, as before). With heal: false the picked faces are removed and the gap stays open, leaving the remaining faces as a surface body (kernel remove_faces); deleting every face is refused. Saved only when false, noted under format 18.
Display meshes after opening, the face names read when a feature finds a face by name, and inspect.measure over all bodies are now worked out per body on plain scoped threads (solidcraft_kernel::for_each_on_threads / map_on_threads), in body order and with the same results; the browser build stays serial.
A sketch text gets an optional style: bold and italic faces (a slanted fallback for italic), left/center/right alignment, letter and line spacing, and a path curve of the same sketch for the baseline to follow (reverse takes the other side). Edit Text gets B/I toggles, alignment, spacing fields and a Path chip, all live. The style is saved only when not plain and is noted under format 18.
solidcraft --control PORT writes a random per-launch token to a user-only file (<data>/control/PORT.token; 0700/0600 on Unix, icacls on Windows; SOLIDCRAFT_CONTROL_TOKEN overrides) and refuses any connection whose first request lacks it. mcp --connect, the demo and packaging smoke clients send it. MCP execute/batch/open/save/export/screenshot are annotated destructive and open-world, new_design destructive. Docs: control-protocol.md, mcp.md, AGENTS.md, pending release note in releasing.md.

Renaming a body used to replace every string in later features equal to its old name, including sketch text, plane and feature names and expressions. Now only values under keys that name bodies (body, bodies, target, targets, tools) at any depth are rewritten, with a test that a sketch text spelling the body's name stays while a move follows the rename.
A hole drilled square to a flange's panel, not only the base's, is now a flat cut-out of the sheet: it unfolds with its panel to where the bend allowance puts it, shows in the flat pattern and DXF as a circle, and survives unfold and refold. A pocket tool spans the cut-outs already inside it (a counterbore's hole), so the order they are made in no longer matters. Fixes#560.
When an extrude cuts with profiles whose outlines stay more than 1 µm apart (the letters of a text), their tools are apart too, so they are joined and cut from the body in one boolean instead of one per profile. A ten-letter text cut drops from about 13 s to 1.5 s with the same result. Sheet metal targets and touching profiles keep cutting tool by tool. Tapered extrudes are unaffected.
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.
