## Current Objective
|
||||
Rebaseline Phase 1 before any more implementation: use the revised `docs/MITC4_FORMULATION.md` as the MITC4 gate, decide how `references/quad_02.inp` should be handled despite its `Part/Assembly/Instance` structure, and draft new sprint contracts before reworking the solver.
|
||||
Execute the new Phase 1 rebaseline plan in `phases/1-linear-static-mitc4-rebaseline`. The old `phases/1-linear-static-mitc4` path is historical and superseded by the paper-based MITC4 formulation reset.

- Phase directory: `phases/1-linear-static-mitc4`
|
||||
- Execute with: `python scripts/execute.py 1-linear-static-mitc4`
|
||||
- Step numbering is zero-based for the harness: `step0.md` corresponds to milestone P1-01, and `step15.md` corresponds to milestone P1-16.
|
||||
- Every step file contains a sprint contract with objective, scope, allowed files, tests-first plan, reference-artifact policy, evaluator checklist, acceptance command, and handoff requirements.
|
||||
- Current phase status: rebaseline required. Do not resume the old P1-15/P1-16 path until new contracts are drafted against the revised MITC4 formulation and the `quad_02` compatibility decision.

|
||||
- Step numbering is zero-based. `step0.md` starts with a rebaseline audit, and `step15.md` is the independent evaluator closeout.
|
||||
- Every step file contains a sprint contract with objective, required reading, scope, allowed files, explicit non-goals, tests to write first, reference artifacts, acceptance command, evaluator checklist, and handoff requirements.
|
||||
- Historical phase directory: `phases/1-linear-static-mitc4`
|

|
||||
| R-012 | pending | planner + evaluator | Draft a Phase 1 redo plan and step contracts that replace or supersede the old P1-01 through P1-16 implementation path where it conflicts with the revised MITC4 formulation. | `docs/HARNESS_ENGINEERING.md`, `docs/MITC4_FORMULATION.md` |
|
||||
| R-011 | partial | generator + Abaqus compatibility evaluator | Resolve through rebaseline step 1: review `references/quad_02.inp` and `references/quad_02_displacements.csv`; either add a normalized Phase 1-compatible derivative input or create an explicit parser compatibility plan. | `phases/1-linear-static-mitc4-rebaseline/step1.md`, `docs/ABAQUS_INPUT_SUBSET.md`, `docs/VERIFICATION_PLAN.md` |
|
||||
| R-013 | pending | user + verification agent | Add enough additional small Abaqus S4 reference cases for the PRD target of three stored Phase 1 references: one single-element case, one simple multi-element plate/shell case, and one curved shell benchmark. | `docs/PRD.md`, `docs/VERIFICATION_PLAN.md` |
|
||||
|
||||
## Phase 1 Definition Of Done

## Current Status
|
||||
Phase 1 is being rebaselined before more implementation. P1-01 through P1-14 have an initial C++17 implementation, but it is no longer authoritative until reviewed against the revised paper-based `docs/MITC4_FORMULATION.md`. The user added `quad_02.inp` and `quad_02_displacements.csv`; `quad_02` uses `TYPE=S4`, but still includes `Part/Assembly/Instance` and `*Density`, so the next planner must decide whether to normalize it or add a dedicated parser compatibility sprint.
|
||||
Phase 1 has a new rebaseline phase definition in `phases/1-linear-static-mitc4-rebaseline`. The old `phases/1-linear-static-mitc4` path is historical and superseded after the MITC4 formulation reset. P1-01 through P1-14 have an initial C++17 implementation, but it is no longer authoritative until reviewed against the revised paper-based `docs/MITC4_FORMULATION.md`. `quad_02` is now the stored S4 reference pair, but its `Part/Assembly/Instance` and `*Density` features remain a compatibility decision for rebaseline step 1.

|

|
||||
Summary:
|
||||
- Added a new 16-step Phase 1 rebaseline phase that supersedes the old Phase 1 execution path while preserving the old phase as historical record.
|
||||
- Split the redo into audit, reference onboarding, core guardrails, parser/domain, validation diagnostics, DOF/reaction foundation, results/comparator, MITC4 geometry, MITC4 covariant strain tying, material/integration, stiffness/drilling, patch benchmarks, assembly, linear static workflow, stored-reference regression, and evaluator closeout.
|
||||
- Updated `PLAN.md` so new agents execute `phases/1-linear-static-mitc4-rebaseline` and treat the old `1-linear-static-mitc4` phase as blocked/superseded.
|
||||
- Kept unresolved decisions visible: `quad_02` normalization versus explicit parser compatibility sprint, RF CSV availability, and the PRD target of three stored Phase 1 reference cases.
|
||||
|
||||
Verification:
|
||||
- Parsed `phases/index.json` and `phases/1-linear-static-mitc4-rebaseline/index.json` with PowerShell `ConvertFrom-Json`.
|
||||
- Verified all 16 rebaseline step files contain the required sprint contract sections from `docs/HARNESS_ENGINEERING.md`.
|
||||
- `python scripts/validate_workspace.py` configured CMake, built `fesa_core` and `fesa_tests`, and ran CTest successfully.
|
||||
- CTest result: 1 test executable passed.
|
||||
|
||||
Follow-up:
|
||||
- Start with `python scripts/execute.py 1-linear-static-mitc4-rebaseline` when ready.
|
||||
- Step 1 must resolve how to use `quad_02` without silently expanding parser support.

# 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

||||
- /PROGRESS.md
|
||||
- /PLAN.md
|
||||
- /docs/README.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`

||||
|
||||
## 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.

# Sprint Contract: Reference Onboarding
|
||||
|
||||
## Objective
|
||||
Create a Phase 1 reference path for `quad_02` without modifying the original Abaqus artifact or silently expanding parser support.
|
||||
|
||||
## Required Reading
|
||||
- /AGENTS.md
|
||||
- /PROGRESS.md
|
||||
- /PLAN.md
|
||||

|
||||
- /references/quad_02.inp
|
||||
- /references/quad_02_displacements.csv
|
||||
|
||||
## Scope
|
||||
- Inspect `quad_02` and document its supported and unsupported features.
|
||||
- Add a normalized Phase 1-compatible derivative input if selected by the planner, keeping the original `quad_02.inp` unchanged.
|
||||
- Add notes or manifest metadata for unit system, source solver, expected outputs, and tolerances.
|
||||
|
||||
## Allowed Files
|
||||
- `references/`
|
||||
- `docs/ABAQUS_INPUT_SUBSET.md`
|
||||
- `docs/VERIFICATION_PLAN.md`
|
||||
- `PLAN.md`
|
||||
- `PROGRESS.md`
|
||||
- `tests/` only for reference artifact parsing/comparator tests
|
||||
|
||||
## Explicit Non-Goals
|
||||
- Do not implement `Part`, `Assembly`, or `Instance` parser support in this step unless this contract is revised first.
|
||||
- Do not edit `references/quad_02.inp` or `references/quad_02_displacements.csv`.
|
||||
- Do not compare solver displacements until the MITC4 rebuild and end-to-end workflow are complete.
|
||||
|
||||
## Tests To Write First
|
||||
- Test that original `quad_02.inp` is recognized as stored provenance with unsupported `Part/Assembly/Instance`.
|
||||
- If a normalized input is added, test that it contains only the documented Phase 1 subset.
|
||||
- Test `quad_02_displacements.csv` column loading and 121-row node-label parsing.
|
||||
|
||||
## Reference Artifacts

||||
```
|
||||
|
||||
## Evaluator Checklist
|
||||
- Original Abaqus files are preserved.
|
||||
- Any normalized derivative file has a clear name and provenance note.
|
||||
- Parser scope remains aligned with `docs/ABAQUS_INPUT_SUBSET.md`.
|
||||
- Tolerances and result mapping are documented before regression use.
|
||||
|
||||
## Handoff Requirements
|
||||
- Update `PROGRESS.md` with reference files changed or added.
|
||||
- Update `PLAN.md` if parser compatibility remains blocked.
|
||||
|
||||
## Do Not
|
||||
- Do not treat `*Density` as material support.
|
||||
- Do not allow `Part/Assembly/Instance` through the Phase 1 parser accidentally.
