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

bherbruckandClaude Opus 5.5 38a6ae3d38 Topology counts: a horn torus pinched to a point is one face (smoothness ignores an edge's ends and points without a normal), with a degenerate loop at the pinch counted as Fusion does (two edges and a vertex); oracle 50 passes, 76/76

bherbruckandClaude Opus 5.5 109b8acbb5 Topology counts weld coincident vertices and edges, and merge two pieces of one surface only across an edge that just those two share: tangent holes touching along a line keep the wall cut at the pinch, the same way at every pinch (oracle 42 passes; 75/76)

bherbruckandClaude Opus 5.5 46f3ff713d Fillets of edges meeting at corners in any selection order: blends go one at a time in an order that works (a run along a planar loop waits for a selected edge meeting its inner corner, then bridges the arc it left), so three edges at a box corner give a sphere octant

bherbruckandClaude Opus 5.5 3e7826fe56 Fillets and chamfers along closed chains of curved edges between any two smooth sides (a branch pipe meeting a main pipe): a ball rolled along the edge gives the contact curves and the blend (rational B-spline through exact arcs, smooth across the chain's joints); side faces trimmed to the contacts and seams shortened; merged topology joins free-form faces that meet smoothly by their exact normals

Export: ExportCommand/CLI --out/MCP export with .3mf write a 3MF Core package
([Content_Types].xml, _rels/.rels, 3D/3dmodel.model; millimetres), one
mesh object and build item per body, named after it, vertices shared and
welded watertight (T-junctions between faces split), base-material colours
when bodies carry one (STEP colours now ride on bodies). Tessellation as
for STL. File > Export 3MF.

Import: doc.open/drag-drop/CLI/MCP open accept .3mf and .stl; Insert Mesh
(ParaMeshInsertAlignCommand) adds them to a design as a MeshImport feature.
Kernel mesh bodies render, measure exactly, move and export; solid
features refuse them with a clear error. 3MF reading flattens components
and build transforms, converts units, reads colours; sizes, entries,
nesting and element counts are capped.

bherbruckandClaude Opus 5.5 a97af44979 M0: truck-based kernel with local fillets and chamfers, parametric document timeline 
The kernel moved from monstertruck to truck: truck's booleans handle blind
holes, pockets and bosses that monstertruck's did not (see the ADR). Fillets
and chamfers on straight convex edges between planar faces are our own exact
local B-rep operation. The document holds parameters with unit-aware
expressions and a timeline that re-evaluates incrementally.
