# C++ 모듈화와 공개 API 정리
## 목적과 개발 결과
모델·요소·assembly·procedure·backend·I/O 책임을 분리하고 공개 header의 vendor 의존을
격리했다. Naming/format/header guard·Doxygen 계약과 HDF5/reference 동작의 보존을 확인했다.
당시 revision·명령·수치 결과와 환경 실패는 [검증 기록](verification.md)에 남긴다.
## 재사용 Handoff
현재 architecture·수명은 [ARCHITECTURE](../ARCHITECTURE.md), C++ 규약은
[CODINGSTYLE](../CODINGSTYLE.md), 실행은 [operations](../operations.md)를 따른다.
실제 공개 header와 대응 src consumer를 함께 읽으며 `.hpp` 시절의 API명·임시 Step 명령을
다시 도입하지 않는다. 원본 reference와 물리·tolerance를 리팩터링 편의로 바꾸지 않는다.
## 실패와 교훈
상속된 `FESA_HARNESS_CODEX_SANDBOX`로 Python default 계약 검사가 실패했던 사례는 환경
오분류를 피하는 근거다. Clang-format의 변경 유무와 exit를 분리하고 link 성공만으로
MSVC runtime·dependency 설정이 완성됐다고 판단하지 않는다. 그때의 pass는 현재 codebase
전체의 재검증 결과가 아니다.

| clang-format repository dry-run | Pass: 163 files. |
| clang-tidy selected public-header check | Pass: 46 headers, exit 0, zero naming diagnostics outside the two documented contract exceptions. |

| Header extension policy | Pass: 0 `.hpp` under `include`, `src`, `tests`. |
| Fresh MSVC x64 Debug configure | Pass. |
| MSVC x64 Debug build | Pass: `fesa_tests`. |
| CTest discovery | Pass: 206 tests. |
| Full CTest | Pass: 206/206. |
| Approved reference suites | Pass: 3/3. |
| Reference tree no-change | Pass before and after compare: `git diff --exit-code 1e5758f -- reference` exit 0. |
## Failure classification and failed test inventory
Blocking classification: `none`.
Nonblocking diagnostics:
- `environment`: inherited `FESA_HARNESS_CODEX_SANDBOX=danger-full-access` caused the raw pytest command to fail one default-sandbox test. The same pytest command passed 21/21 in a child process with only that override removed.
- `style`: initial clang-format dry-run reported four whitespace/line-ending findings. Formatting normalization introduced no tracked source-content diff, and the rerun passed.
- `static-policy`: clang-tidy reported header-guard trailing underscores and two
`const` parameters because its generic macro/constant categories differ from the
higher-priority FESA guard and parameter conventions. It reported no other naming
diagnostics, and the required command exited 0.
Failed blocking tests after clean verification: none.
## Handoff recommendation
Proceed to Physics Evaluation Agent. Build/test evidence is sufficient for the final
Implementation-owned gate; no compile, link, test, reference-comparison, or
environment blocker remains.
## No-change assertion
No production behavior, reference artifact, reference tolerance, comparator contract,
or generated Doxygen output was changed in Step 24.
## Open issues
None blocking.

# C++ Object-Oriented Modular Refactoring Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use
> `superpowers:subagent-driven-development` (recommended) or
> `superpowers:executing-plans` to implement this plan task-by-task. Steps use
> checkbox (`- [ ]`) syntax for tracking.
>
> In FESA, those task-by-task semantics are mediated by the project Harness. Do not
> invoke an implementation skill or select a Step directly; a separate user request
> must start `scripts/execute.py`, which selects exactly one pending Step.
**Goal:** Preserve the current B33, MITC4, and linear-static numerical and external
contracts while converting the FESA C++ production code to explicit object-oriented
boundaries, focused modules, shared utilities, Google C++ style, and production-only
Doxygen documentation.
**Architecture:** Domain owns immutable polymorphic semantic definitions through
`std::unique_ptr` and stable `EntityIndex` positions. `ElementDefinition` remains
separate from runtime numerical `Element`, and load, boundary-condition, analysis,
material, and property abstractions each have independent hierarchies. Existing
deterministic assembly, result identity, HDF5 schema, and reference comparison
contracts remain unchanged.
**Tech Stack:** C++17, MSVC x64 Debug, CMake, CTest, GoogleTest, Intel oneMKL,
Intel oneTBB, HDF5, clang-format, clang-tidy, and optional Doxygen configuration.
## Global Constraints
- Follow `/docs/CODINGSTYLE.md` and the official Google C++ Style Guide baseline.
- Use PascalCase for every C++ function and accessor; use `.h` production headers
with full-path include guards; retain `.cpp` as the FESA source-file exception.
- Add Doxygen comments only to production code. Do not add Doxygen coverage to tests.
- Keep C++17 and MSVC x64 Debug compatibility and add no compiler warnings under
`/W4 /WX`.
- Preserve the approved B33 and MITC4 formulations, signs, units, coordinate systems,
reduction order, result row identity, HDF5 schema, tolerances, and reference files.
- Do not implement MITC3, solid elements, dynamics, eigenvalue analysis, response
spectrum, random vibration, density, plasticity, anisotropy, distributed load, body
force, or MPC behavior.
- Do not expose MKL, TBB, HDF5, Win32, or vendor integer types from public solver-core
headers.
- Every C++ production change requires a related C++ test and an in-Step
`RED -> observed failure -> minimal GREEN -> focused/full VERIFY` cycle.
- Do not run `scripts/execute.py` until the user gives a separate explicit execution
request.
- Doxygen comments and `Doxyfile` configuration are in scope; generated Doxygen
output is deferred and is not a blocking command for this phase.

| `source_requirement` | `/docs/superpowers/specs/2026-08-16-cpp-object-oriented-modular-refactoring-design.md` |

| `date` | `2026-08-16` |
## 2. Readiness Check
- The written refactoring design and the 25-Step draft were explicitly approved on
2026-08-16.
- B33 and MITC4 requirements, formulations, numerical reviews, I/O projections, and
reference contracts already exist and remain upstream read-only inputs.
- Required reference inputs and CSVs are present under
`/reference/cantilever beam/` and `/reference/shell/`.
- `clang-format.exe` and `clang-tidy.exe` are present at
`C:/Program Files/LLVM/bin/`; the current long-lived process PATH need not contain
that directory because the plan uses the absolute paths.
- Doxygen generation is intentionally deferred by user decision. The implementation
still adds production comments and a warning-strict `Doxyfile` for later use.
- No missing formulation, tolerance, HDF5 projection, or artifact decision prevents
implementation planning.
## 3. Implementation Scope
### Included
- Repository policy/tooling and Implementation Agent enforcement.
- Mechanical `.hpp` to `.h`, header guard, PascalCase, formatting, and production
Doxygen conversion in reviewable module slices.
- Shared `Vector3`, dense-BLAS internal adapter, ASCII utilities,
`SourceTargetResolver`, and owner-based DOF invariant validation.
- Independent abstract boundaries for material, element property, semantic element
definition, runtime element, load, boundary condition, and analysis.
- Current concrete B33, MITC4, isotropic linear elasticity, beam/shell property,
concentrated nodal load, prescribed displacement, and linear-static behavior.
- Responsibility-based splits of domain mapping, result recovery, and HDF5 writing.
- Full MSVC/CTest and existing B33/MITC4 external reference verification.
### Excluded and non-goals
- New physics, input keywords, output datasets, tolerances, reference artifacts, or
runtime performance optimization.
- A common root base shared by unrelated element, load, material, and analysis types.
- A giant material interface containing density, plasticity, and anisotropy options.
- Registry/plugin frameworks, global static registration, speculative `Clone()`, or
unnecessary shared ownership.

| `T21` | domain-mapper-modules | `T11`, `T13`, `T18`, `T19` | Mapper split by semantic responsibility. |
| `T22` | result-recovery-modules | `T17` | Recovery split into global, beam, shell, and commit responsibilities. |
| `T23` | hdf5-writer-modules | `T17`, `T22` | HDF5 writer split without schema changes. |
| `T24` | final-quality-reference-gate | all prior tasks | Full style, build/test, HDF5, determinism, and reference evidence. |
Each task maps one-to-one to `/phases/cpp-object-oriented-modular-refactoring/stepN.md`.
## 6. TDD Test Plan
| Test ID | First failing evidence | GREEN evidence |
| --- | --- | --- |
| `P-AGENT-001` | Python contract reports missing mandatory `CODINGSTYLE.md` input. | Agent workflow contract passes. |
| `P-STYLE-001` | Policy test reports missing or incorrect clang/Doxygen configuration. | Policy and full Harness Python tests pass. |
| `C-STYLE-001..004` | Test includes/calls use `.h` and PascalCase before production conversion, causing a compile failure. | Focused module suites and full CTest pass. |
| `C-VEC3-001` | `vector3_test.cpp` cannot compile because `Vector3` is absent. | Arithmetic, finite, and normalization-boundary tests pass. |
| `C-DUP-001..004` | Tests reference the new shared seam before it exists. | Shared seam passes and old duplicate helper definitions are absent by `rg` checks. |
| `C-MODEL-001..002` | Polymorphic ownership and const stable-index tests fail before semantic bases exist. | Material/property/definition tests and Domain mapping tests pass. |
| `C-ELEMENT-001` | Base-interface creation and incompatibility tests fail before `ElementFactory`. | B33/MITC4 creation, rejection, stiffness, and recovery tests pass. |
| `C-DOF-001` | Fake runtime element layout is not accepted by DofManager. | Stable scatter/pattern and invariant tests pass. |
| `C-ASSEMBLY-001` | Fake runtime contribution is not assembled. | Serial/TBB/repeated CSR outputs remain byte-identical. |
| `C-RECOVERY-001` | Fake result bundle cannot flow through recovery. | Beam/shell identities, signs, energy, and atomic rollback pass. |
| `C-LOAD-001` | A fake Load cannot emit ordered full-DOF contributions. | Source-order accumulation and current load validation pass. |
| `C-BC-001` | A fake BoundaryCondition cannot resolve constraint definitions. | Nonzero prescribed displacement and reconstruction pass. |
| `C-ANALYSIS-001` | LinearStaticAnalysis cannot be invoked through `Analysis`. | Approved factorization/load/solve/recovery lifecycle passes. |
| `C-MODULE-001..003` | Tests reference extracted mapper/recovery/HDF5 responsibilities before their seams exist. | Existing public behavior and atomicity suites pass after extraction. |
| `C-REF-B33-001` | No new intentional failure; final gate reuses the approved external comparison. | B33 comparison passes under its existing component-scale tolerance. |
| `C-REF-MITC4-001` | No new intentional failure; final gate reuses the approved external comparison. | MITC4 translations pass at fixed `1.0e-5`; rotations remain warning-only. |
RED and GREEN evidence, command, exit code, duration, output tail, and failed test names
must be recorded during execution in the Implementation-owned reports. A final reference
gate does not manufacture an artificial RED because it verifies an unchanged approved
external contract after all refactoring tasks.
## 7. CMake/CTest Plan
- Keep the existing `fesa_solver`, `fesa_cli`, `fesa_unit_tests`,
`fesa_integration_tests`, `fesa_reference_tests`, and `fesa_tests` targets.
- Register new production/test files in `/src/fesa/CMakeLists.txt` and
`/tests/CMakeLists.txt` in their owning task.
- Do not create a new test executable or change existing test labels.
- `.harness/config.json` is absent, so use `.harness/build`, MSVC x64, Debug, and the
explicit local dependency paths recorded in each Step.
- Every C++ task runs a focused CTest regular expression and the full CTest discovery
and execution sequence.
- Step `T24` performs a fresh configure and the final B33/MITC4 reference tests.
## 8. Candidate Files and Ownership
| Responsibility | Candidate files |
| --- | --- |
| Policy/tooling | `.codex/agents/implementation-agent.toml`, `.clang-format`, `.clang-tidy`, `Doxyfile`, `tests/test_agent_skill_workflow_contract.py`, `tests/test_cpp_policy_contract.py` |
| Fixed/dynamic math | `include/fesa/math/vector3.h`, `include/fesa/math/vector.h`, `include/fesa/math/matrix.h`, `src/fesa/math/dense_blas_internal.h`, matching `.cpp` and unit tests |
| Semantic material/property | `include/fesa/materials/*.h`, `include/fesa/properties/*.h`, `src/fesa/materials/*.cpp`, `src/fesa/properties/*.cpp`, matching unit tests |
| Semantic element definitions | `include/fesa/elements/element_definition.h`, concrete definition headers, `include/fesa/model/domain.h`, `src/fesa/model/domain.cpp` |
| Runtime elements | `include/fesa/elements/element.h`, `element_factory.h`, existing B33/MITC4 kernels and new factory implementation/tests |
| Source resolution | `include/fesa/model/source_target_resolver.h`, `src/fesa/model/source_target_resolver.cpp`, focused tests |
| Solver consumers | DofManager, SparseAssembler, ResultRecovery headers/sources/tests |
| Loads | `include/fesa/loads/load.h`, `concentrated_nodal_load.h`, sources, LoadAssembler and tests |
| Constraints | `boundary_condition.h`, `prescribed_displacement.h`, `essential_constraint_policy.h`, sources and tests |
| Analysis | `analysis.h`, `linear_static_analysis.h`, sources and integration tests |
| Mapper split | focused private mapper modules under `src/fesa/io/abaqus/` with one public `domain_mapper.h` facade |
| Recovery split | focused modules under `src/fesa/results/` with one public `result_recovery.h` facade |
| HDF5 split | private modules under `src/fesa/io/hdf5/` with one public `hdf5_results_writer.h` facade |
These are implementation candidates, not permission to introduce extra public API. Each Step
must choose the minimum files consistent with the approved boundaries.
## 9. Candidate Interface Contracts
The implementation may refine parameter carrier names while preserving these semantic contracts:
```cpp
struct AnalysisRequest {
std::filesystem::path input_path;
std::filesystem::path output_path;
};
class Analysis {
public:
virtual ~Analysis() = default;
virtual Status Run(const AnalysisRequest& request) = 0;
};
class ElementDefinition {
public:
virtual ~ElementDefinition() = default;
virtual ElementDefinitionKind Kind() const noexcept = 0;
virtual const SourceEntityId& SourceId() const noexcept = 0;
virtual const std::vector<EntityIndex>& NodeIndices() const noexcept = 0;
virtual EntityIndex PropertyIndex() const noexcept = 0;
};
class Element {
public:
virtual ~Element() = default;
virtual const ElementDofLayout& DofLayout() const noexcept = 0;
virtual Result<ElementStiffnessContribution> ComputeStiffness() const = 0;
virtual Result<ElementResultBundle> Recover(
const Vector& full_displacement) const = 0;
};
class Load {
public:
virtual ~Load() = default;
virtual Result<std::vector<LoadContribution>> ComputeContributions(
const LoadContext& context) const = 0;
};
class BoundaryCondition {
public:
virtual ~BoundaryCondition() = default;
virtual Result<std::vector<ConstraintDefinition>> ResolveConstraints(
const BoundaryConditionContext& context) const = 0;
};
```
Do not add future-only methods to these bases. Factory compatibility may use a centralized,
explicit kind discriminator followed by a checked concrete access; consumers must not scatter
`dynamic_cast` or B33/MITC4 switches.
## 10. Data Flow Contract
```text
existing Abaqus .inp
-> syntax reader
-> responsibility-split semantic mappers
-> immutable Domain-owned definitions
-> AnalysisModel non-owning active view
-> ElementFactory runtime elements
-> DofManager / deterministic assembly / constraints
-> LinearStaticAnalysis
-> result recovery candidate and validation
-> authoritative results.h5 atomic commit
-> test-only deterministic projection
-> existing Abaqus CSV comparison by source identity and component
```
- B33 input and CSVs remain under `/reference/cantilever beam/` with their current
names and component-scale tolerance.
- Blocking MITC4 S4 input/displacement CSV remains under `/reference/shell/` with
fixed absolute tolerance `1.0e-5` for U1/U2/U3 and warning-only UR1/UR2/UR3.
- `/reference/shellR/` is not promoted into a blocking comparison.
- No reference artifact is renamed, rewritten, regenerated, or normalized.
## 11. Acceptance Traceability Matrix
| Requirement | Tasks | Tests/evidence | Acceptance |
| --- | --- | --- | --- |
| `R-PRESERVE-001` | `T03..T24` | all current suites, `C-REF-B33-001`, `C-REF-MITC4-001` | Full CTest and blocking references pass. |

## 12. Validation Commands
Harness Python and policy validation:
```powershell
uv run --with pytest python -m pytest -v -rs
& "C:/Program Files/LLVM/bin/clang-format.exe" --version
& "C:/Program Files/LLVM/bin/clang-tidy.exe" --version
& "C:/Program Files/LLVM/bin/clang-tidy.exe" --verify-config
```
MSVC clean configure and full verification:
```powershell
$requiredBuildPaths = @(
"C:/git/googletest",
"C:/Program Files (x86)/Intel/oneAPI/mkl/2026.1/lib/cmake/mkl",
"C:/Program Files (x86)/Intel/oneAPI/tbb/2023.1/lib/cmake/tbb",
"C:/Program Files/HDF_Group/HDF5/2.1.1/cmake"
)
foreach ($requiredBuildPath in $requiredBuildPaths) {
if (-not (Test-Path -LiteralPath $requiredBuildPath)) {
throw "Missing $requiredBuildPath"
}
}
cmake --fresh -S . -B .harness/build -G "Visual Studio 18 2026" -A x64 `
"-DFESA_GTEST_SOURCE_DIR=C:/git/googletest" `
"-DMKL_DIR=C:/Program Files (x86)/Intel/oneAPI/mkl/2026.1/lib/cmake/mkl" `
"-DTBB_DIR=C:/Program Files (x86)/Intel/oneAPI/tbb/2023.1/lib/cmake/tbb" `
"-DHDF5_DIR=C:/Program Files/HDF_Group/HDF5/2.1.1/cmake"
cmake --build .harness/build --config Debug --target fesa_tests

ctest --test-dir .harness/build -C Debug --output-on-failure
ctest --test-dir .harness/build -C Debug `
-R "B33ReferenceComparison|Mitc4S4Reference" --output-on-failure
```
Repository style and artifact checks:
```powershell
$cppFiles = @(rg --files include src tests -g "*.h" -g "*.cpp")
& "C:/Program Files/LLVM/bin/clang-format.exe" --dry-run --Werror $cppFiles
$publicHeaders = @(rg --files include/fesa -g "*.h")
foreach ($publicHeader in $publicHeaders) {
& "C:/Program Files/LLVM/bin/clang-tidy.exe" --config-file=.clang-tidy `
$publicHeader -- -x c++ -std=c++17 -Iinclude
if ($LASTEXITCODE -ne 0) {
throw "clang-tidy failed for $publicHeader"
}
}
$legacyHeaders = @(rg --files include tests -g "*.hpp")
if ($legacyHeaders.Count -ne 0) {
$legacyHeaders
throw "Legacy .hpp headers remain"
}
git diff --exit-code 1e5758f -- reference
```
Doxygen generation is deliberately absent from the blocking commands. When the user
requests documentation generation later, execute `doxygen Doxyfile` and treat warnings
as failures without committing generated HTML.
## 13. Risks and Downstream Handoff
- Global API/header renaming has a wide compile blast radius. Mechanical style Steps
are isolated from semantic restructuring to keep failures attributable.
- Domain polymorphism can accidentally destabilize vector indices or lifetimes. Tests
must prove insertion order, const access, and AnalysisModel non-owning lifetime.
- Virtual element recovery can tempt a giant result record. Preserve distinct beam and
shell rows in a backend-neutral bundle rather than adding meaningless common fields.
- Moving vector helpers can change floating-point operation order. Preserve each
formulation expression order and use exact regression where no approved tolerance
applies.
- File splits can leak vendor dependencies through public headers. Keep all HDF5/MKL/TBB
types in private implementation modules.
Downstream handoff is one bounded handoff to `implementation-agent` through the
Coordinator: execute only the Executor-selected `stepN.md`, read `/docs/CODINGSTYLE.md`
before C++ work, record RED/GREEN/VERIFY evidence, and do not advance another Step.
## 14. Harness Step Draft
- Task name: `cpp-object-oriented-modular-refactoring`
- Steps: `step0.md` through `step24.md` in dependency order shown in Work Breakdown.
- Every Step contains its own prerequisite files, test-first failure, candidate
interfaces, exact focused/full commands, and prohibitions.
- Stop conditions are an upstream contract conflict, a missing declared artifact at
final comparison, an unresolved environment dependency, or repeated build/test
failure. In each case only the current Step status payload is changed.
- Planning approval materializes these files but does not authorize
`python scripts/execute.py cpp-object-oriented-modular-refactoring`.
## 15. Open Issues
- No blocking architecture, formulation, I/O, reference, or tolerance issue remains.
- Doxygen executable use and generated documentation are deferred by explicit user
decision; this does not waive production Doxygen comments or `Doxyfile` configuration.

## Scope and no-change assertion
Step 24 added no production behavior, no comparator/tolerance changes, and no
reference artifact changes. The only implementation-owned source action during this
step was running `clang-format -i` on four files that the dry-run style gate reported;
`git diff --raw`, `git diff --numstat`, and `git diff --check` for those files were
empty after the run, so no tracked source-content diff was introduced.
No Doxygen executable, hook entry point, `scripts/execute.py`, Abaqus, Nastran,
reference solver, commit, or push was run.
## Prior Step RED/GREEN/VERIFY evidence
The final gate reviewed the Executor-recorded Step 0-23 summaries. Each prior step is
already `completed` in the phase index and retains its Executor-owned timestamps.

| `R-SCOPE-001` | No production behavior or future-feature changes in Step 24; reference tree diff against `1e5758f` is empty. |
All acceptance traceability rows from the approved implementation plan are listed
above. Their owning task rows `T00..T23` retain the recorded RED/GREEN/VERIFY
summaries, and `T24` supplies the final style, build, CTest, artifact, HDF5,
comparison, and no-change evidence.
## Handoff
Implementation gate verdict: `pass-for-physics-evaluation`.
Open issues: none blocking. The inherited `FESA_HARNESS_CODEX_SANDBOX` override is an
environment note only; the clean child-process policy command passed without code
changes.

The generated `comparison.json` files are the deterministic machine-readable
per-row decision records. The summaries below preserve row counts, worst rows,
precheck/tolerance decisions, and artifact hashes for audit.
## HDF5-to-CSV projection and tolerance contracts
### B33
- Model: `cantilever-beam-b33`
- HDF5 datasets:
- `/steps/Step-1/frames/0/nodal/displacement`
- `/steps/Step-1/frames/0/nodal/reaction`
- `/steps/Step-1/frames/0/element/section_resultant`
- Row identity: model, `Step-1`, frame `0`, instance `PART-1_1-1`, source node label, quantity, component.
- Components:
- displacement `UX/UY/UZ/URX/URY/URZ`
- reaction `RF1/RF2/RF3/RM1/RM2/RM3`
- section resultant `N/T/My/Mz`
- Tolerance: `absolute_floor + 1.0e-6 * reference_scale`, with reference scale from read-only Abaqus rows only; displacement/rotation floor `1.0e-9`, force/moment floor `1.0e-3`.
- Pre-tolerance policy: missing, extra, duplicate, nonfinite, schema-mismatched, or identity-mismatched rows fail before tolerance.
### MITC4 S4
- Case: `shell-s4`
- Source element type: `S4`
- Internal formulation: `FESA-MITC4`
- Integration rule: `2x2x2-gauss; mitc4-edge-midpoint-shear`
- HDF5 dataset: `/steps/Step-1/frames/0/nodal/displacement`
- Row identity: case, instance, source node label, component.
- Components: `U1/U2/U3` blocking; `UR1/UR2/UR3` warning-only.
- Tolerance: fixed absolute `1.0e-5` for every U/UR row; no component scale, row denominator, zero clamp, omission, or averaging affects the decision.
- Pre-tolerance policy: missing, extra, duplicate, nonfinite, header-mismatched, or identity-mismatched projected rows fail before tolerance.
## CLASSIFY
Blocking classification: `pass`.
No missing, extra, duplicate, nonfinite, schema-mismatched, identity-mismatched, or
tolerance-failed blocking row was reported by either generated comparison.
### B33 row and metric decisions
Overall: `passed=true`; row decisions: 176/176 passed; failed rows: 0; nonfinite row

Result: exit 0, `<no reference diff>`.
No reference input, CSV, tolerance, comparator contract, or generated reference
artifact was modified. Generated FESA outputs are confined to `.harness/build/`.
## Open issues
None blocking. Passing comparison is only an implementation handoff to physics
evaluation; it is not release readiness or physics approval.

Step 24 is a final verification gate and did not manufacture a new RED condition;
it reused the approved B33 and MITC4 reference comparisons after style and full
build/test verification.

| `R-DOC-001` | Policy pytest passed; 63/63 production headers had header guards and Doxygen contracts, while 0 test files contained imposed Doxygen tags. Doxygen generation was intentionally not run. |
| `R-DUP-001` | Step 7-9 summaries record the shared `Vector3`, element/result/I/O preservation tests, and duplicate-definition scans with zero remaining local definition families; full CTest 206/206 passed. |
| `R-DUP-002` | Steps 10, 11, and 15 record the single dense-BLAS adapter, shared ASCII/source resolver, and DofManager-owned invariant logic with focused tests and helper/branch scans; full CTest 206/206 passed. |
| `R-MODEL-001` | Steps 12-13 record polymorphic Material/ElementProperty/ElementDefinition ownership and stable Domain views; focused ownership tests and full CTest passed. |
| `R-ELEMENT-001` | Step 14 records semantic/runtime separation, fail-closed factory compatibility checks, virtual destruction, owner-bounded views, and zero `dynamic_cast` uses; full CTest passed. |
| `R-PIPELINE-001` | Steps 15-17 record generic DofManager, SparseAssembler, and ResultRecovery seams with fake runtime elements, deterministic/atomic tests, and zero concrete B33/MITC4 consumer branches; full CTest passed. |
| `R-LOAD-001` | Step 18 records Domain-owned Load objects, ordered contributions, validation-before-candidate accumulation, and focused LoadAssembler tests; full CTest passed. |
| `R-BC-001` | Step 19 records BoundaryCondition definitions and stable essential-constraint partition/reconstruction, including nonzero and `0 x 0 Kff` cases; full CTest passed. |
| `R-ANALYSIS-001` | Step 20 records minimal base `Run()` dispatch and procedure-owned lifecycle tests, including factorize-before-load, exactly-one factorization, all-constrained solve, and writer suppression on recovery failure; full CTest passed. |
| `R-MODULE-001` | Steps 21-23 record the approved Domain-mapper, result-recovery, and HDF5 private component splits with facade, diagnostic, identity, rollback, self-check, and atomic-finalization tests; full CTest passed. |
| `R-AGENT-001` | Step 0 records the mandatory `docs/CODINGSTYLE.md` implementation-agent contract; the final clean-environment policy suite passed 21/21. |
| `R-SCOPE-001` | No production behavior or future-feature changes in Step 24; reference tree diff against `1e5758f` is empty. |
All acceptance traceability rows from the approved implementation plan are listed
above. Their owning task rows `T00..T23` retain the recorded RED/GREEN/VERIFY
summaries, and `T24` supplies the final style, build, CTest, artifact, HDF5,
comparison, and no-change evidence.
<a id="implementation-report--handoff"></a>
### Handoff
Implementation gate verdict: `pass-for-physics-evaluation`.
Open issues: none blocking. The inherited `FESA_HARNESS_CODEX_SANDBOX` override is an
environment note only; the clean child-process policy command passed without code
changes.

<a id="build-test--failure-classification-and-failed-test-inventory"></a>
### Failure classification and failed test inventory
Blocking classification: `none`.
Nonblocking diagnostics:
- `environment`: inherited `FESA_HARNESS_CODEX_SANDBOX=danger-full-access` caused the raw pytest command to fail one default-sandbox test. The same pytest command passed 21/21 in a child process with only that override removed.
- `style`: initial clang-format dry-run reported four whitespace/line-ending findings. Formatting normalization introduced no tracked source-content diff, and the rerun passed.
- `static-policy`: clang-tidy reported header-guard trailing underscores and two
`const` parameters because its generic macro/constant categories differ from the
higher-priority FESA guard and parameter conventions. It reported no other naming
diagnostics, and the required command exited 0.
Failed blocking tests after clean verification: none.
<a id="build-test--handoff-recommendation"></a>
### Handoff recommendation
Proceed to Physics Evaluation Agent. Build/test evidence is sufficient for the final
Implementation-owned gate; no compile, link, test, reference-comparison, or
environment blocker remains.

<a id="reference-comparison--hdf5-to-csv-projection-and-tolerance-contracts"></a>
### HDF5-to-CSV projection and tolerance contracts
<a id="reference-comparison--b33"></a>
#### B33
- Model: `cantilever-beam-b33`
- HDF5 datasets:
- `/steps/Step-1/frames/0/nodal/displacement`
- `/steps/Step-1/frames/0/nodal/reaction`
- `/steps/Step-1/frames/0/element/section_resultant`
- Row identity: model, `Step-1`, frame `0`, instance `PART-1_1-1`, source node label, quantity, component.
- Components:
- displacement `UX/UY/UZ/URX/URY/URZ`
- reaction `RF1/RF2/RF3/RM1/RM2/RM3`
- section resultant `N/T/My/Mz`
- Tolerance: `absolute_floor + 1.0e-6 * reference_scale`, with reference scale from read-only Abaqus rows only; displacement/rotation floor `1.0e-9`, force/moment floor `1.0e-3`.
- Pre-tolerance policy: missing, extra, duplicate, nonfinite, schema-mismatched, or identity-mismatched rows fail before tolerance.
<a id="reference-comparison--mitc4-s4"></a>
#### MITC4 S4
- Case: `shell-s4`
- Source element type: `S4`
- Internal formulation: `FESA-MITC4`
- Integration rule: `2x2x2-gauss; mitc4-edge-midpoint-shear`
- HDF5 dataset: `/steps/Step-1/frames/0/nodal/displacement`
- Row identity: case, instance, source node label, component.
- Components: `U1/U2/U3` blocking; `UR1/UR2/UR3` warning-only.
- Tolerance: fixed absolute `1.0e-5` for every U/UR row; no component scale, row denominator, zero clamp, omission, or averaging affects the decision.
- Pre-tolerance policy: missing, extra, duplicate, nonfinite, header-mismatched, or identity-mismatched projected rows fail before tolerance.
<a id="reference-comparison--classify"></a>
### CLASSIFY
Blocking classification: `pass`.
No missing, extra, duplicate, nonfinite, schema-mismatched, identity-mismatched, or
tolerance-failed blocking row was reported by either generated comparison.
