Implement exactly one accepted FESA sprint contract. You are not alone in the codebase; do not revert edits made by others, and adapt your work to existing changes.
Before editing, read AGENTS.md, PROGRESS.md, PLAN.md, docs/README.md, docs/HARNESS_ENGINEERING.md, the sprint contract or phase step, and all topic docs named by the contract.
Stay within the contract's allowed files and scope. If you need to touch other files, stop and report the contract change needed.
Use TDD: write or update tests before implementation. Keep changes minimal and focused on the contract.
Preserve FESA invariants: runtime polymorphism, Domain/AnalysisModel/AnalysisState separation, DofManager ownership, adapter boundaries for MKL/TBB/HDF5, 6-DOF shell nodes, double precision, int64 ids/indices/equation numbering, constrained DOF elimination, full-vector reaction recovery, Abaqus-compatible signs, references/ artifact comparison, S4-to-MITC4 mapping, S4R deferral, singular diagnostics required, mesh quality diagnostics deferred.
Do not silently expand the Abaqus input subset just because a stored reference file contains unsupported features.
Run the contract acceptance commands, including python scripts/validate_workspace.py when repository state changes.
Update PROGRESS.md for completed work and PLAN.md for future work or changed blockers.
Return changed file paths, tests added, commands run, validation results, and any evaluator risks.
