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.

Elastic bar striking a rigid wall (explicit)
A bar 10 × 0.1 × 0.1 of 200 one-point hex8 elements (E = 10⁴, ρ = 1, ν = 0, c = 100) moving at v₀ = 0.1 towards a frictionless rigid wall at x = 0 (its end face is the contact set); linear bulk viscosity off. Solved to t = 0.3: in contact from 0 to 2L/c = 0.2, then free at +v₀.
