# Sprint Contract: Rebaseline Audit
|
|
|
|
## Objective
|
|
Audit the existing Phase 1 implementation against the paper-based `docs/MITC4_FORMULATION.md` and produce a concrete rework map before changing solver behavior.
|
|
|
|
## Required Reading
|
|
- /AGENTS.md
|
|
- /PROGRESS.md
|
|
- /PLAN.md
|
|
- /docs/README.md
|
|
- /docs/HARNESS_ENGINEERING.md
|
|
- /docs/PRD.md
|
|
- /docs/ARCHITECTURE.md
|
|
- /docs/ADR.md
|
|
- /docs/NUMERICAL_CONVENTIONS.md
|
|
- /docs/MITC4_FORMULATION.md
|
|
- /phases/1-linear-static-mitc4/index.json
|
|
|
|
## Scope
|
|
- Inspect existing C++ implementation and tests only enough to classify what can be retained, rewritten, or deleted in later steps.
|
|
- Produce or update planning notes in `PLAN.md` and `PROGRESS.md`.
|
|
- If useful, add a short audit artifact under `phases/1-linear-static-mitc4-rebaseline/`.
|
|
|
|
## Allowed Files
|
|
- `PLAN.md`
|
|
- `PROGRESS.md`
|
|
- `phases/1-linear-static-mitc4-rebaseline/`
|
|
|
|
## Explicit Non-Goals
|
|
- Do not change production C++ behavior.
|
|
- Do not rewrite MITC4 formulas.
|
|
- Do not unblock stored-reference regression by accepting unsupported Abaqus syntax.
|
|
|
|
## Tests To Write First
|
|
- None. This is a planning and audit sprint.
|
|
|
|
## Reference Artifacts
|
|
- `references/quad_01.inp`
|
|
- `references/quad_01_displacements.csv`
|
|
- `references/quad_02.inp`
|
|
- `references/quad_02_displacements.csv`
|
|
|
|
## Acceptance Commands
|
|
```bash
|
|
python scripts/validate_workspace.py
|
|
```
|
|
|
|
## Evaluator Checklist
|
|
- The audit identifies conflicts with `docs/MITC4_FORMULATION.md`, especially old averaged-edge basis, `1.0e-6` drilling scale, analytic thickness integration, and direct shear evaluation risks.
|
|
- Future work is assigned to later rebaseline steps instead of being fixed here.
|
|
- `PLAN.md` and `PROGRESS.md` describe the new state without treating the old P1-01 through P1-14 implementation as authoritative.
|
|
|
|
## Handoff Requirements
|
|
- Record completed audit work in `PROGRESS.md`.
|
|
- Keep next implementation tasks in `PLAN.md` or later step files.
|
|
|
|
## Do Not
|
|
- Do not merge this audit with implementation.
|
|
- Do not remove old phase history.
