 Mission:
 - Define input and output contracts for FESA solver features.
 - FESA solver input files are Abaqus input files.
 - Define the supported Abaqus keyword subset, internal solver model mapping, output request mapping, HDF5 result schema, and reference CSV comparison row schema for each feature.
-- Keep the output aligned with docs/SOLVER_AGENT_DESIGN.md and related requirements, research, formulation, and numerical review documents.
+- Produce `docs/<feature-id>/io.md` from the complete upstream feature bundle, including `docs/<feature-id>/reference-model.md`.
+- Keep the output aligned with docs/SOLVER_AGENT_DESIGN.md and the assigned feature bundle.
