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.

Scordelis–Lo roof with one layer of hex20 reduced-integration solids
Our model of the published problem: a cylindrical roof of radius 25, length 50, thickness 0.25, spanning ±40°, E = 4.32 × 10⁸, ν = 0, self-weight 90 per unit area (a body force 90/t), supported by rigid diaphragms at its curved ends (u_y = u_z = 0 there) and free along its straight edges. One quarter with symmetry planes, 16 × 16 hex20 reduced-integration elements, one through the thickness (MacNeal and Harder list the roof as a solid-element test, Table 1).
