 5. Review Jacobian rules, determinant checks, derivative transforms, and distortion handling.
 6. Review integration rule, Gauss points, weights, and full/reduced/selective integration policy.
 7. Check element residual, internal force, external force, stiffness, tangent, symmetry, and positive definiteness expectations.
-8. Assess rigid body modes, patch test readiness, hourglass, shear locking, volumetric locking, singular Jacobian, conditioning, and convergence risk.
-9. Decide status: `pass-for-implementation-planning`, `needs-formulation-revision`, `needs-research`, `needs-reference-model`, or `blocked`.

 - Confirmed defects, risks, open questions, and test recommendations are separated.
 - Missing derivations are returned to Formulation Agent instead of being silently fixed.
 - Evidence gaps are routed to Research Agent or Reference Model Agent.
