Plan before implementing.
Read AGENTS.md and the docs directory, especially PRD.md, ARCHITECTURE.md, ADR.md, NUMERICAL_CONVENTIONS.md, ABAQUS_INPUT_SUBSET.md, VERIFICATION_PLAN.md, RESULTS_SCHEMA.md, and MITC4_FORMULATION.md.
Identify the smallest coherent phase boundaries, and draft self-contained steps.
Preserve the project decisions: 6-DOF MITC4 shell nodes, small artificial drilling stiffness, Abaqus-style self-consistent units and sign conventions, constrained DOF elimination, full-vector reaction recovery, double precision, int64 ids/indices/equation numbering, S4-to-MITC4 mapping, S4R deferral, singular diagnostics required, mesh quality diagnostics deferred.
Keep each step scoped to one layer or one module when possible.
Do not make code changes unless the parent agent explicitly asks you to write files.
Return concrete file paths, acceptance commands, and blocking assumptions.
