The params doc listed start_offset? with no description, and an extrude in direction negative with a positive start offset surprised a user. The behaviour is unchanged (an offset start plane, as in Fusion); the params doc of solid.extrude and the Extent field doc say so.

The loft's top lies in the pocket floor. truck's boolean cannot take coincident faces, and the exact polygon fallback (planar_boolean) only takes bodies whose faces are all planar, so the hole's cylinder ruled out the only path that handles this cut. planar_boolean now first tries a sliced form: when an axis-aligned slab holds the tool and none of the body's curved faces, the body is split on the slab's planes (planes clear of the body's own faces), the planar middle piece takes the exact boolean, and the pieces outside are glued back on along the cut faces (the middle piece is healed first so its edges match theirs). Pieces in several parts are refused rather than glued into one shell. split_by_plane's half-space code is now ops::half_space, which this uses.
Tests: loft_cut_beside_a_round_hole replays examples/regressions/loft_cut_beside_round_hole.json and checks the exact volume (slab - pocket - prismatoid - hole; fails on main). With the hole made after the loft, the body is the same (volume, area, 19 faces, 42 edges).

Moving a body transforms its intersection-curve edges, and truck-geometry 0.5.0 scales each curve's tolerance by the operator norm of the matrix. matext4cgmath 0.1.0 computes it from eigenvalues through a quartic whose Newton refinement loops while the residual is above a tolerance and never gives up. For a translation matrix all four eigenvalues are 1, and near that quadruple root the iteration can cycle forever (about one translation in eight of the boolean retries' shifts, by a scan of sizes 0.1-2000 mm). matext4cgmath is vendored with both Newton loops stopped after 100 steps (vendor/README.md, ATTRIBUTION.md).
truck master no longer computes the norm in transform_by, so the vendored copy can go once a truck release after 0.5.0 is adopted.
Tests: moving_a_body_with_an_intersection_curve_edge_ends (kernel) cuts a cylinder with a tilted box and moves the result by one of the shifts that hung (hangs on main). examples/regressions/oblique_cut_of_cylinder_hang.json is the variant of the oblique cut that hung the app; it hangs on main, and since the previous commit it passes without reaching the shifted retries, so it is replayed by the engine test as a scenario only.

The boolean checks its result by meshing both operands and the result, then sampling membership densely where the operands' boxes overlap. The mesh step came from the larger body's size (0.46 mm here), which facets the bar's 3 mm arc so coarsely that two meshes of the same arc disagree over a few percent of the thin overlap box, and a correct cut failed the 0.4 % mismatch limit. The step now also follows the smallest side of the overlap box (2e-3 of it), never finer than 1e-5 of the size, so it only changes where the bodies meet in a region much thinner than they are. truck's first result for the cut is then accepted, and it matches a split of the bar by the tilted plane.
Tests: oblique_cut_through_a_small_arc_matches_a_split replays examples/regressions/oblique_cut_of_cylinder.json and compares with solid.split_body by the same plane (fails on main). The full suite runs no slower.

heal_keep evaluated the result's intersection curves outside any guard. truck panics where such a curve no longer evaluates, and the panic escaped boolean_whole, so the retries and fallbacks that would have succeeded never ran. heal_keep now runs under guard and returns the solid unhealed when healing panics (as its doc already promised for failures), and the boolean builds its result body under guard too, so a result that cannot be built counts as a failed attempt.
Tests: shallow_loft_cut_from_the_top_face replays examples/regressions/shallow_loft_cut_from_top_face.json and checks the exact prismatoid volume (fails on main with the panic).

Use egui pointer ownership for viewport navigation and picking, view-cube
interaction, and sketch-dimension hover. Cover scrolling, model selection,
and cube interaction under floating dialogs, including after they close.
Shield constraint glyph and move-gizmo highlights from overlapping UI too.
Clear strict Clippy warnings and use the same saved path in the recent-file
scenario on Windows and Unix.
Fixes#87
Group kernel pieces across circular rims and hidden surface seams for hovering, selection, dialogs, and measurement. Preserve physical references and cover full-item toggling and picking with regression tests.
Fixes#88
kernel::fillet_variable_points(body, edge, start, [(position, radius)...], smooth): the radius law is a B-spline of the edge parameter (straight pieces, or C1 cubic pieces with Catmull-Rom slopes), and since every section's arc is affine in its radius the blend is exactly a rational B-spline (degree 2 across, the law's degree along) with B-spline contact curves on the faces. The largest radius along the edge decides whether the blend fits. Fillet type variable takes mid: [[position, radius expr], ...] and smooth; middle radii are parameters of the feature (Mid radius) and follow user parameters. Tests: straight pieces against (1 - pi/4) L (a^2 + ab + b^2) / 3 per piece, smooth against the integrated law, either end as start, refusals; engine test with a parameter-driven middle radius.

- solvecraft-cli fuzz / fuzz-one: seeded random modelling sessions (boxes, extruded profiles with arcs, revolves; joins and cuts of boxes, cylinders and spheres, fillets, chamfers, shells, holes, patterns) on a grid that makes coincident faces and tangencies common, every step checked (command ok, every body a sound solid via the new Body::validity, volume moving the right way), plus the boolean volume identity on random primitives; one process per seed with a time limit; failures minimised to scripts
- shell/offset: corners where a curved face meets another at an angle are refined onto the moved surfaces (Newton); edges that are neither lines nor arcs are rebuilt through their moved points; one shell per piece; faces that would cross say so (not supported yet) instead of leaving a cavity inside out; flat revolved faces count as planes; the unhealed body is tried when the healed one fails
- cylinders start their seams at an odd angle (grid-aligned seams broke booleans along them)
- partial revolves of profiles touching the axis build no zero-area face on the axis
- booleans on bodies in several pieces retry a piece at a time
- regression tests for each, and a fixed set of seeds in cargo test

The merged face count no longer joins faces across a Split Face line, and Offset Face's same-surface grouping stops there. A piece whose move the body's topology cannot follow (its neighbour stays put) is swept along its normal and joined on or cut in, giving walls along the split line as in Fusion. Engine test: a split box top counts 7 faces; one half up 5 (27000 mm³), the other down 3 (25200 mm³).

Split Face records the new edges as polylines on the body (Body::split_lines); the document carries them through later features. STEP export no longer joins pieces of one surface across such a line, and healing (fillets, chamfers, booleans, shell, draft) no longer merges coplanar pieces there, while incidental pieces (boolean leftovers, seam halves) still merge as before. Tests: plane and cylinder splits keep their face count through a STEP round trip (and join without the record), a second split keeps both lines, and an engine test exports a split box after a fillet with 8 faces.

Release assets are now the programs themselves: SolveCraft and solvecraft-cli .exe for Windows,
plain Linux binaries plus the AppImage, a macOS .dmg (SolveCraft.app with an Applications link) and
the universal CLI binary; only the web app stays a zip. The notes template takes {tag}, says to
chmod +x on Linux and macOS, and GitHub adds the change list.
Since no LICENSE or NOTICE file rides along any more, the programs carry them:
THIRD-PARTY-LICENSES.txt (written by `cargo xtask licences` from cargo metadata and each shipped
crate's own licence files, 419 crates; `cargo xtask ci` checks it is current) is embedded with
