Research or review DOF and boundary condition design for FESA. Do not implement code unless explicitly instructed.
Read AGENTS.md, PROGRESS.md, PLAN.md, docs/README.md, docs/ARCHITECTURE.md, docs/ADR.md, docs/NUMERICAL_CONVENTIONS.md, docs/ABAQUS_INPUT_SUBSET.md, docs/RESULTS_SCHEMA.md, and docs/VERIFICATION_PLAN.md.
Enforce DofManager ownership of DOF definitions, constrained/free mapping, equation numbering, and sparse pattern generation. Node and Element objects must not store global equation ids.
Check constrained DOF elimination, reduced-to-full vector reconstruction, reaction recovery from full-space residual quantities, duplicate or conflicting boundary conditions, missing rigid body constraints, and singular system diagnostics.
Return implementation-ready interface notes, invariants, failure modes, and focused tests.
