jyvikoandClaude Opus 5.5 6d9452ad84 Verification oracle: tests/oracle cases, cargo xtask oracle, fixtures, docs/oracle.md, CI job
The oracle binary (modelcraft-testkit) runs each case's recipe through the
command engine, measures its quantities by JSON pointers into step outputs
or commands, compares them with the cited references and the frozen
fixtures, and writes docs/oracle.md. 20 theory cases (patch tests of every
solid element, Timoshenko cantilevers, Lame, Kirsch, beam frequencies,
torsion and bending through couplings, explicit waves and impact, CDT
invariants), 8 published benchmarks (MacNeal-Harder patch, straight and
curved cantilevers, thick cylinder, Scordelis-Lo with solids, NAFEMS LE1,
LE10, FV32) and 10 pending cases with citations.

Constrained Delaunay mesh of a stepped block: exact volume, valid elements

The corpus part stepped-block (three boxes, a pocket cut through), built with SolidCraft from design.json, tetrahedralized by mesh.tet.generate. Every boundary face is planar, so the tessellation is exact and the mesh's volume must equal 47000 to rounding.
