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

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.
