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.

Pure bending through a distributing coupling
A 20 × 1 × 2 bar of 20 × 2 × 4 hex20 elements clamped at x = 0; its end face is coupled to a reference point by a distributing coupling, and a moment of 10 about y acts on the point (E = 1000, ν = 0).
