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

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)

Booleans about twice as fast: point-in-mesh tests through a per-direction grid (sampling checks), one mesh of the result for both its volume and membership checks, operand volumes from their meshes, and the intersection tried at the coarser tolerance first (oracle run 10 → 5 minutes); free-form faces merge in the topology counts when their normals agree within 2.5°

Merged topology: a sphere's normals must be radial too (torus strips no longer pass for spheres), so torus pieces merge (40)

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

Shell and offset faces on bodies of planes and cylinders (filleted boxes, bosses: each face moves along its normal, cylinders change radius, corners and arcs follow); surface classification leaves out singular points (cone apexes); recipes: holes on cylinders drill toward the axis

STEP export: unique ids, plain curves, right revolution senses; seams on split faces
...
Vendored truck-stepio (writer only): an intersection curve's second surface
was written at the first one's id (duplicate ids for every boolean edge),
and revolved surfaces lost their orientation (the modeling-surface sense was
always true; inverted or mirrored revolutions came out inside out). Export
now writes intersection edges as C1 cubic B-splines through exact points,
so files carry plain 3D curves and no redundant surfaces.
Vendored truck-meshalgo: hinted parameter searches that run off a B-spline's
domain are rejected or clamped (meshing their grid never finished).
STEP import: straight revolution profiles are bounded in the meridian plane
and stop at the axis; loops on revolutions start away from the axis; face
extents include edge end points. Edges between pieces of one split surface
draw as seams.
kernel::step_validate checks a STEP file (duplicate ids, dangling
references, dense numbering); the oracle replay now exports every rebuilt
part, validates it and re-imports it with no warnings and the same volume
(all 32 rebuildable cases pass).

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.
