bherbruck d6cdec40da Fix modelling regressions and reconcile WIP UI work 2026-10-10 15:37:00 -04:00
CypherNaugh_0x aa268f0f0e Faster tests: hostile_params_never_panic shares its commands across threads (154 s to 20 s), the design-file fuzz test tries its seeded cases on all cores (21 s to 7.5 s), the kernel's tangent-primitive boolean test runs its three seeds at once, and the headless scenario harness skips the software viewport render it threw away every frame (scenarios 63 s to 26 s). kill_mid_save waits for the saver to reach a varying round instead of sleeping a fixed time, so it holds on a busy machine 2026-10-10 13:24:08 -04:00
CypherNaugh_0x 9508ee749c Shell refuses a wall thicker than a rim instead of returning a corrupt body: the topology-preserving face offset now checks every planar face's moved loops, and a loop that turns inside out or two loops that cross (a rim or ledge narrower than the move, e.g. a bowl opening sliding past the slab's outer edge) is an error naming the spot. Before, the self-crossing cavity went into the boolean and the shelled body came back with roughly twice its volume and its centre of mass outside the body, so every later cut failed its volume check 
The check is geometric, not a tuned threshold: on the reported basin (18 mm rim, sloped bowl wall) the rim strip reaches zero width at 15.17 mm and the shell is refused from there on. Tolerances only absorb rounding (scaled to the body size), and at most 2000 straight edges per face are compared pairwise. Arc edges and curved faces are not checked.

This is a guard, not the full fix. Building such a shell needs the offset to change topology: drop the strip that collapses and let its neighbours meet, as offset_body already does for rounds thinner than the move, extended to planar faces. That is substantially more work in the most delicate part of the kernel (rims, ledges, steps, arc-bounded strips) and is left for a separate change; until then the workaround is to model the hollow directly (an offset loft and a box cut).

bherbruckandClaude Opus 5.5 67c79ec91c Lips on rounded, shelled rims: the band along the rim's edge is raised from the body's own faces (kernel::raise_band: the rim face split along the band's exact offset edge, the band's walls swept up from the walls below, a top), since a join can't merge walls that continue each other; grooves cut with a band reaching into the free side so no wall coincides; tests against the band's area times its height 
Fixes #29

bherbruckandClaude Opus 5.5 80f5a58806 Re-land the robustness batch on main (#6): fillets running into an earlier round go to blend_corner (any radius) instead of the same-radius undo; the lip and drilled-hole regression tests move into tests/robustness.rs with the new command ids; measuring 5000 faces is checked for its counts, its time in an ignored perf test run alone

bherbruckandClaude Opus 5.5 ccde7a4837 Robustness runs and the kernel fixes they found 
- 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
