# 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`.

## 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.
