# FESA Multi-Agent Plan
## Purpose
This file tells a new AI Agent what work is planned and how to continue without reconstructing project intent from the full conversation.
New Agents must read `AGENTS.md`, this file, `docs/PROGRESS.md`, `docs/WORKNOTE.md`, and `docs/AGENT_RULES.md` before editing files.
## Active Objective
Build the FESA structural solver foundation around the initial feature `mitc4-linear-static-shell`.
## Repository Context
- Canonical remote repository: `https://teagit.mimi1011.synology.me/baram2584/FESADev.git`
- Default remote name: `origin`
- Shared baseline branch: `dev`
- New task branches should use `codex/<short-task-name>` unless the user requests otherwise.
## Current High-Level Plan
1. Maintain project-level documentation and handoff files.
2. Analyze new solver feature requirements for `mitc4-linear-static-shell`.
3. Gather research evidence for MITC4, OpenSees `ShellMITC4`, Abaqus S4/S4R, patch tests, and Scordelis-Lo.
4. Write FEM formulation for the MITC4 linear static shell feature.
5. Define Abaqus `.inp` input subset and HDF5 output/reference schemas.
6. Define stored Abaqus S4R/S4 reference model bundles.
7. Write a TDD implementation plan.
8. Implement C++17/MSVC code using CMake/CTest, MKL, TBB, and HDF5.
9. Compare FESA HDF5 results against stored Abaqus S4R reference artifacts using `abs-or-rel 1e-5`.
10. Prepare release documentation after reference verification passes.
## Acceptance Criteria
- Every solver feature follows the stage-gated workflow in `AGENTS.md`.
- C++ production changes are test-first.
- `python scripts/validate_workspace.py` remains the default validation path.
- MITC4 reference comparison covers nodal displacement, reaction, element internal force/resultant, and stress.
- Result comparison uses a single tolerance value `1e-5` with absolute-or-relative pass logic.
- Agents can identify the canonical git remote and shared baseline branch from the project handoff documents.
## Coordination Rules
- Update this file when the plan, scope, ordering, or acceptance criteria change.
- Update `docs/PROGRESS.md` after completing work or running validation.
- Update `docs/WORKNOTE.md` after mistakes, failed approaches, environment traps, or decisions that future Agents should not rediscover.
- Keep `.codex/agents/*.toml` and `.codex/skills/*/SKILL.md` pointed at `docs/AGENT_RULES.md` for common operating rules.
- Verify `git status --short --branch` and `git remote -v` at the start of git-aware work.
## Known Blockers
- No CMake project exists yet, so `python scripts/validate_workspace.py` currently takes the no-op path.
- Abaqus reference artifacts are not generated by Agents and must be supplied by a human-approved process.
## Known Environment Facts
- HDF5 is installed locally at `C:\Program Files\HDF_Group\HDF5\2.1.1`; CMake should use `HDF5_ROOT` for this root or `HDF5_DIR` for `C:\Program Files\HDF_Group\HDF5\2.1.1\cmake`.
