A cut or an intersection between prisms (a plate and the tools through it) is now decided in 2D before either operand is meshed. A body's size and volume are measured once, a placement reads its orientation from its matrix, the evaluation cache is bounded to 64 MiB, and STEP import copies fewer shells. Hole plates evaluate 20-30% faster with less memory, and models are unchanged.

A cut of stepped prisms sews a wall over one segment through successive
slabs as one face, and the generated planar walls are then joined on
their common supports. Until now such a piece carried no history.
- prism_lineage: a sewn wall records what it is over in each slab it
spans (Spec::Wall { levels, slabs }), so a coalesced wall comes from
the operand walls under it in every slab
- the sewn piece's history is attached before the joining and carried
through it (Built::Traced); planar_regularize composes the history of
the body it joins with the join itself
- a composed face is Split only where record::mark_shared_split finds an
origin under several faces; an inner Split alone no longer makes one
- Body::same ignores history: an operation that leaves a body as it is
gives the same body, carrying that operation's history
The two boolean history tests that waited for this run again, and the
coalesced and regularized step cuts are covered.

EdgeOrigin::Meet now names each side as a Side: the sorted, de-duplicated
origins of the face there. substitute maps a side to the union of the inner
faces' origins, so a meeting with a face an inner operation merged keeps its
lineage; meeting() derives sides from whole faces. Fillets after box cuts
that leave coplanar pieces now report exact history. Prism lineage meets a
cap of several origins and resolves wall junctions away from shared
vertices by the operand's one edge between the walls. bore_union's recut
reports history only for a one-face bore (pieces of a two-arc bore's recut
wall were given both arcs).

Fillets (local, loop, rolling ball, corner, variable, chord), chamfers
(cutters, local corners, loops, two sides), shell, draft, offset faces,
split face/body, delete face, patch/copy/stitch/trim/extend and
transforms record their history over [body] while they build: faces
rebuilt from the body's, blends in place of edges (corner patches in
place of the edges at the corner), shell walls as offsets, edges as
pieces of the body's or where two faces meet. Multi-step operations
compose each step. The push-face offset fallback now has history, and
the bore union composes its narrowed tool.
A reflection reorders a body's edges, so transforms now match edges by
identity (mirrored copies reported the wrong edges).

ops::boolean's result carries its history over [a, b] whichever path made
it, recorded by the code that builds the faces:
- truck path (incl. jitter retries): shapeops history mapped through the
order-preserving copies and the cut's turned tool, then through healing
- heal records which input faces each healed face merges and which input
edges each joined or exact edge replaces (HealMap); opt-in, so heal_keep
callers pay nothing
- trivial shortcuts, the void, glue, faces pushed apart (push_faces records
its own history; the slab cut back on a union maps to the operands'
faces in that plane), the nudged retry, by_lumps and join composition
- prism booleans: section segments carry tags (operand cap edge, the wall
beside it, its vertices) through the 2D boolean; walls, caps and edges of
the extruded or sewn result follow from them
- planar and faceted polygon booleans: polygons carry their operand face;
faces join the pieces across edges, edges come from the pieces either side
History gains renumber/over (and consuming forms) for composition;
record gains regions/traced/build helpers. truck-shapeops
*_with_history now return the solid with an Option history. Paths that
cannot report (bore narrowing via offset, inexpressible lineage) leave the
result without history. Boolean results, tolerances and fallback order are
unchanged.

One numbered loop type (crate::numbered) carries each segment's profile
numbers through orientation, snapping, circle re-seaming, re-sampling and
rotation; every builder orients its regions through it once. Builders that
make their own side faces pair each face with its provenance as it is made
(ruled walls by the wire edges each face holds, smooth lofts, coils and path
sweeps by segment), and cap_and_close appends the caps itself. Column
following is kept only for faces truck sweeps internally (rsweep, tsweep
along paths, cones, where an apex vertex stays put). Extrude derives face
sources and history in one topology pass. One attach entry point takes
operands with their edges already indexed.
Geometry, face order, face sources and recorded origins are unchanged.

Extrude, revolve (partial and full turn), tapered extrude, loft (incl. to a
point), sweep, path sweep, coil, primitives, lip, emboss and thicken attach
the exact history of the bodies they build: each face's profile segment, cap
or operand face, and each edge's operand edge, recorded by topology identity
inside the building call. Nothing is sampled; a body whose faces do not follow
the expected construction carries no history. Face sources are unchanged.
