+# Evaluation Feedback: P1A-09 Architecture Evaluator Closeout
+
+Date: 2026-05-05
+Evaluator: Codex
+
+## Verdict
+
+pass
+
+## Findings
+
+No material architecture, guardrail, numerical-convention, parser-subset, result-schema, or validation regressions were found.
+
+## Evidence
+
+- Required project guardrails and topic documents were read before evaluation: `AGENTS.md`, `PROGRESS.md`, `PLAN.md`, `docs/README.md`, `docs/HARNESS_ENGINEERING.md`, `docs/ARCHITECTURE.md`, `docs/ADR.md`, `docs/NUMERICAL_CONVENTIONS.md`, `docs/ABAQUS_INPUT_SUBSET.md`, `docs/VERIFICATION_PLAN.md`, `docs/RESULTS_SCHEMA.md`, and `docs/MITC4_FORMULATION.md`.
+- `include/fesa/fesa.hpp` is now an umbrella include facade only. A direct search for implementation tokens such as `namespace fesa {`, `inline`, `class`, `struct`, `enum`, and `using` in that file returned no matches.
+- Production symbols are no longer concentrated in `fesa.hpp`; they are separated under the documented module families in `include/fesa/Analysis`, `include/fesa/Assembly`, `include/fesa/Boundary`, `include/fesa/Core`, `include/fesa/Element`, `include/fesa/IO`, `include/fesa/Load`, `include/fesa/Math`, `include/fesa/Material`, `include/fesa/Property`, `include/fesa/Results`, and `include/fesa/Util`.
+- Matching `src/` module directories and thin `.cpp` compile units exist for the architecture module set, and `CMakeLists.txt` compiles `src/*.cpp` recursively into `fesa_core`.
+- Current implementation bodies remain mostly inline in module headers. This is accepted for this refactor because the sprint contracts allowed module headers or implementation files and the migration goal was to remove `fesa.hpp` as the primary implementation body. If stricter `.cpp` implementation ownership is desired later, it should be handled by a dedicated ABI/build-time hardening contract.
+- `Node`, `Element`, and the lightweight `Material` domain record remain under `Core` as planned in the P1A-00 migration map to avoid a `Core -> Element` or `Core -> Material` dependency cycle. Element kernels and MITC4 material-law helpers are owned by `Element` and `Material`.
+- Direct module include tests exist for Core, Math, IO, Results, Element, MITC4 stiffness, Assembly, and Analysis.
+- `quad_02_phase1` remains the executable stored-reference path for Phase 1, and the displacement CSV regression is still covered by the main validation test suite.
+
+## Checklist
+
+| Item | Result | Notes |
+|---|---|---|
+| Contract compliance | PASS | Evaluation-only step changed only phase/status/handoff files. |
+| Architecture alignment | PASS | `fesa.hpp` is a facade; module ownership is now visible under `include/fesa/*` with matching `src/*` compile units. |
+| Numerical conventions | PASS | No DOF order, precision, int64, constrained/free mapping, or full-vector RF behavior was changed. |
+| Abaqus subset discipline | PASS | No new parser support was added; unsupported Abaqus/CAE scaffolding remains outside Phase 1 parser scope. |
+| MITC4 formulation | PASS | No formulation, tying sign, integration, drilling, or stiffness behavior was changed by this evaluator step. |
+| Results schema | PASS | `U` and `RF` result model behavior remains covered by tests. |
+| Reference verification | PASS | `references/quad_02_phase1.inp` and `references/quad_02_displacements.csv` remain the active stored displacement regression path. |
+| Validation | PASS | `python scripts\validate_workspace.py` passed; CTest reported 9/9 test executables passed. |
+| Handoff | PASS | Phase status, `PLAN.md`, and `PROGRESS.md` were updated. |
+
+## Residual Non-Blocking Gaps
+
+- R-010 remains open: reaction-force CSV artifacts are not yet onboarded with a documented schema, tolerance, and automated comparison.
+- R-013 remains open: the PRD target of three stored Phase 1 reference cases is not yet satisfied.
+- Optional future hardening: move large inline module bodies from public headers into `.cpp` files if compile-time, ABI, or encapsulation policy later requires it. This should not be mixed with solver behavior changes.
+
+## Acceptance Commands
+
+```powershell
+python scripts\validate_workspace.py
+```
+
+Result:
+
+- CMake configure succeeded.
+- `fesa_core` and all test executables built successfully.
+- CTest passed 9 of 9 test executables.
+- Validation succeeded.
