FESA Multi-Agent Progress

Current Status

• Project documentation has been reframed from a harness-only project to the FESA structural solver project.
• Initial MITC4 solver implementation plan exists in docs/project-plan/SOLVER_IMPLEMENT_INITIAL_PLAN.md.
• Solver architecture guidance exists in docs/ARCHITECTURE.md.
• ADR and PRD have been updated for MITC4, MKL, TBB, HDF5, tolerance, reference artifacts, and solver state separation.
• Multi-Agent coordination files live under docs/: docs/PLAN.md, docs/PROGRESS.md, and docs/WORKNOTE.md.
• Project plan/design documents live under docs/project-plan/.
• Common per-run AI Agent rules live in docs/AGENT_RULES.md.

Completed

• Defined the nine-step solver development workflow.
• Recorded initial MITC4 feature scope: linear static, MITC4 shell, Abaqus .inp subset, HDF5 output, Abaqus S4R primary reference.
• Recorded tolerance policy: abs(error) <= 1e-5 OR relative(error) <= 1e-5.
• Recorded architecture principles: Domain, AnalysisModel, AnalysisState, DofManager, factory/registry, adapter layers, deterministic TBB assembly, MKL PARDISO, HDF5 result model.
• Moved handoff documents from repository root to docs/.
• Moved solver plan/design documents to docs/project-plan/ and updated agent, skill, test, and document references.
• Extracted common per-run rules from the solver agent design into docs/AGENT_RULES.md.
• Updated .codex/agents/*.toml, .codex/skills/*/SKILL.md, and related tests to reference docs/AGENT_RULES.md instead of the solver agent design document.

In Progress

• Ready for the next stage: requirements baseline for mitc4-linear-static-shell.

Next Tasks

1. Create docs/requirements/mitc4-linear-static-shell.md.
2. Create docs/research/mitc4-linear-static-shell-research.md.
3. Create docs/formulations/mitc4-linear-static-shell-formulation.md.
4. Create docs/io-definitions/mitc4-linear-static-shell-io.md.
5. Create docs/reference-models/mitc4-linear-static-shell-reference-models.md.
6. Create docs/implementation-plans/mitc4-linear-static-shell-implementation-plan.md.

Last Validation

• 2026-06-05: After extracting docs/AGENT_RULES.md, python -m unittest discover -s scripts -p "test_*.py" passed. 85 tests ran successfully.
• 2026-06-05: python scripts/validate_workspace.py passed through the expected no-op path because no root CMakeLists.txt exists yet.
• 2026-06-05: After document relocation and reference updates, python -m unittest discover -s scripts -p "test_*.py" passed. 85 tests ran successfully.
• 2026-06-05: python scripts/validate_workspace.py passed through the expected no-op path because no root CMakeLists.txt exists yet.

Open Questions

• Exact HDF5 C library installation path is not known.
• Stored Abaqus S4R/S4 reference artifact generation process is not yet defined.
