## Current Objective
|
||||
Continue the new Phase 1 rebaseline plan in `phases/1-linear-static-mitc4-rebaseline`, starting with P1R-15 independent evaluator closeout. The old `phases/1-linear-static-mitc4` path is historical and superseded by the paper-based MITC4 formulation reset.
|
||||
The `phases/1-linear-static-mitc4-rebaseline` execution path is complete through P1R-15. Continue by closing the remaining product-level Phase 1 reference gaps before claiming the full PRD Phase 1 Definition of Done. The old `phases/1-linear-static-mitc4` path is historical and superseded by the paper-based MITC4 formulation reset.

## Current Status
|
||||
Phase 1 has a new rebaseline phase definition in `phases/1-linear-static-mitc4-rebaseline`. Steps 0 through 14 are complete. `quad_02_phase1.inp` is now the normalized Phase 1-compatible input path for the stored `quad_02` S4 reference pair, while the original `quad_02.inp` remains preserved unsupported provenance.

Phase 1 has a completed rebaseline execution path in `phases/1-linear-static-mitc4-rebaseline`. Steps 0 through 15 are complete, and P1R-15 recorded a pass-with-documented-gaps evaluator closeout. `quad_02_phase1.inp` is now the normalized Phase 1-compatible input path for the stored `quad_02` S4 reference pair, while the original `quad_02.inp` remains preserved unsupported provenance.

Full PRD Phase 1 completion still depends on the open reference gaps R-010 and R-013. The old `phases/1-linear-static-mitc4` path is historical and superseded after the MITC4 formulation reset.

|

Summary:
|
||||
- Performed the independent closeout review for the `1-linear-static-mitc4-rebaseline` phase.
|
||||
- Recorded a PASS verdict for the rebaseline sprint sequence, with product-level Phase 1 reference gaps explicitly documented instead of silently approved.
|
||||
- Marked P1R-15 complete and marked the rebaseline phase complete in the phase registry.
|
||||
- Updated `PLAN.md` so the next work is closing R-010 and R-013 before claiming full PRD Phase 1 completion.
|
||||
|
||||
Verification:
|
||||
- `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:
|
||||
- R-010 remains open: add Abaqus reaction-force CSV artifacts, preferably `*_reactions.csv`, or explicitly adopt internal equilibrium tests as the Phase 1 RF verification basis until Abaqus RF output is available.
|
||||
- R-013 remains open: add enough additional small Abaqus S4 reference cases for the PRD target of three stored references: one single-element case, one simple multi-element plate/shell case, and one curved shell benchmark.

- The PRD target of three stored Phase 1 reference cases is not yet satisfied; only `quad_02_phase1` is an active stored displacement regression.

# Evaluation Report: P1R-15 Phase 1 Rebaseline Closeout
|
||||
|
||||
Date: 2026-05-04
|
||||
Evaluator: Codex
|
||||
|
||||
## Verdict
|
||||
|
||||
PASS for the `1-linear-static-mitc4-rebaseline` sprint sequence, with documented product-level Phase 1 reference gaps.
|
||||
|
||||
This verdict closes the rebaseline execution path through P1R-15. It does not claim that the broader PRD Phase 1 reference target is fully complete, because R-010 and R-013 remain open in `PLAN.md`.
|
||||
|
||||
## Scope Reviewed
|
||||
|
||||
- `AGENTS.md`
|
||||
- `PLAN.md`
|
||||
- `PROGRESS.md`
|
||||

- `phases/1-linear-static-mitc4-rebaseline/index.json`
|
||||
- Completed rebaseline handoff notes in `PROGRESS.md`
|
||||
|
||||
## Evidence
|
||||
|
||||
- Rebaseline steps P1R-00 through P1R-14 were already marked complete before this evaluation.
|
||||
- `python scripts/validate_workspace.py` passed on 2026-05-04. The command configured CMake, built `fesa_core` and `fesa_tests`, and ran CTest successfully.
|
||||
- The active stored reference regression uses `references/quad_02_phase1.inp` and compares FESA `U` against `references/quad_02_displacements.csv`.
|
||||
- The original `references/quad_02.inp` remains preserved as Abaqus/CAE provenance and is not treated as parser acceptance evidence for `Part/Assembly/Instance`.
|
||||
- `RF` is recovered from the full vector path and covered by in-repo equilibrium/reaction tests; no Abaqus `*_reactions.csv` artifact is available yet.
|
||||
|
||||
## Checklist
|
||||
|
||||
| Item | Result | Notes |
|
||||
|---|---|---|
|
||||
| AGENTS critical rules satisfied | PASS | PLAN/PROGRESS were read before edits, architecture/numerical/reference rules were checked, and Abaqus execution was not required. |
|
||||
| Harness contract followed | PASS | Step 15 stayed inside the allowed evaluation/documentation scope and did not implement missing solver behavior. |
|
||||
| TDD expectations met for implementation steps | PASS | Earlier generator steps recorded failing-first or test-first validation where code was changed; Step 15 is evaluator-only. |
|
||||
| MITC4 formulation alignment | PASS | Rebaseline steps 7 through 11 are tied to the paper-based formulation document and current drilling scale policy. |
|
||||
| Parser subset discipline | PASS | Unsupported Abaqus/CAE provenance remains documented instead of silently expanding the Phase 1 parser subset. |
|
||||
| Full-vector RF recovery | PASS with reference gap | Implementation path preserves full-space stiffness/load state and tests full-vector RF recovery. Abaqus RF CSV comparison remains open as R-010. |
|
||||
| Stored displacement reference regression | PASS with PRD gap | `quad_02_phase1` displacement comparison passes. The PRD target of three stored references remains open as R-013. |
|
||||
| PLAN/PROGRESS synchronized | PASS | Step 15 updates move the active objective to post-rebaseline reference completion. |
|
||||
|
||||
## Residual Gaps
|
||||
|
||||
- R-010: Add Abaqus reaction-force CSV artifacts, preferably `*_reactions.csv`, or explicitly accept internal equilibrium tests as the Phase 1 RF verification basis until Abaqus RF output is available.
|
||||
- R-013: Add enough additional small Abaqus S4 reference cases to satisfy 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.
|
||||
|
||||
## Closeout Decision
|
||||
|
||||
Mark `phases/1-linear-static-mitc4-rebaseline` complete. Continue project work from `PLAN.md` with R-010 and R-013 as the next reference-readiness tasks before claiming full PRD Phase 1 completion.
