- model data와 history data를 구분해야 한다.
- output request와 required Abaqus reference CSV 사이의 연결이 명확해야 한다.

- Reference Model Contract에는 provenance, Abaqus version/source, units, coordinate system, tolerance, reference CSV schema version이 포함되어야 한다.
- 선택 `metadata.json`은 없어도 되며, 존재할 때만 read-only로 참고하고 계약과 대조한다.
- required Abaqus reference CSV가 없으면 완료 상태가 아니라 `needs-reference-artifacts` 상태로 둔다.
- 모든 `must` requirement는 Coverage Matrix에서 model, compared quantity, FESA HDF5 dataset, reference CSV, tolerance, verification method로 추적되어야 한다.

-이 디렉터리는 Reference Verification Agent가 작성하거나 제안하는 기능별 reference comparison report를 보관하는 위치다.
+Reference Verification Agent는 Build/Test 통과 뒤 FESA `results.h5`와 기능이 선언한
+Abaqus CSV quantity를 비교한다. 비교 대상은 observable value이며 Abaqus 내부 formulation
+동등성이 아니다.

-Reference Verification Agent는 Build/Test Executor Agent 통과 후 generated solver `results.h5`와 Abaqus reference CSV files를 tolerance 기준으로 비교한다. Reference CSV는 동일한 Abaqus `.inp` 모델을 Abaqus로 해석해 추출한 변위, 반력, 내력, 응력 결과이며, FESA HDF5 dataset에서 파생된 파일이 아니다. 이 agent는 comparison과 report만 수행하며, source code, tests, CMake files, requirements, formulations, I/O contracts, reference artifacts, tolerance policies를 수정하지 않는다.
-
-기본 문서명은 `docs/reference-verifications/<feature-id>-reference-verification.md` 형식을 사용한다.
-
-## Reference Verification Agent 역할
-
-수행한다:
- `reference/<model-id>/` artifact bundle과 generated solver `results.h5`를 확인한다.
- `model.inp`, required Abaqus reference CSV files, Reference Model Contract의 provenance, reference CSV schema version, FESA HDF5 schema version, units, coordinate system, step/frame identity, node/element ID matching rule, output location, component naming, tolerance policy를 확인한다. 선택 `metadata.json`이 존재하면 read-only로 inventory하고 계약과 대조한다.
- FESA HDF5 dataset을 normalized row record로 읽고 Abaqus reference CSV row와 직접 비교한다.
- comparison command가 FESA `results.h5`에서 deterministic CSV view를 materialize할 수 있지만, 이 파일은 debugging/review용 derived artifact일 뿐 reference artifact가 아니다.
- upstream 문서가 요구할 때만 `<model-id>_strains.csv`, `<model-id>_energy_or_residual.csv`, 또는 `<model-id>_<quantity>.csv`를 추가 비교한다.
- max absolute error, max relative error, RMS error, norm error, worst id/component, missing rows, extra rows, pass/fail을 보고한다.
- 실패를 missing-reference-artifact, missing-solver-output, schema-mismatch, id-mismatch, unit-or-coordinate-mismatch, tolerance-failure, nonfinite-result, upstream-contract, environment로 분류한다.
-
-수행하지 않는다:
- source code를 수정하지 않는다.
- tests를 수정하지 않는다.
- CMake files를 수정하지 않는다.
- requirements, formulations, I/O contracts, reference model contracts를 수정하지 않는다.
- reference artifacts 또는 tolerance policies를 수정하지 않는다.
- Abaqus, Nastran 또는 reference solver를 실행하지 않는다.
- Abaqus reference CSV 파일을 생성하거나 수정하지 않는다.
- solver output을 tolerance에 맞추기 위해 보정하지 않는다.
- physics validation success 또는 release readiness를 승인하지 않는다.
+기본 문서명은 `docs/reference-verifications/<feature-id>-reference-verification.md`다.

 ## 실행 순서

-Reference Verification Agent는 항상 다음 순서를 따른다.
-
 ```text
 ARTIFACT CHECK -> COMPARE -> CLASSIFY -> REPORT
 ```

-`ARTIFACT CHECK`에서 다음 항목이 없으면 비교를 시작하지 않는다.
+`ARTIFACT CHECK`는 다음만 요구한다.

- `model.inp`
- generated solver `results.h5`
- `reference/<model-id>/<model-id>_displacements.csv`
- `reference/<model-id>/<model-id>_reactions.csv`
- `reference/<model-id>/<model-id>_internalforces.csv`
- `reference/<model-id>/<model-id>_stresses.csv`
- reference CSV schema version
- FESA HDF5 schema version
- units
- coordinate system
- step/frame identity
- node/element ID matching rule
- output location
- component naming
- tolerance policy
+- declared `.inp`
+- generated FESA `results.h5`
+- every feature-required Abaqus CSV
+- HDF5 dataset projection
+- source-ID/component mapping
+- blocking/warning behavior
+- approved tolerance

-`metadata.json`은 필수 artifact가 아니다. 파일이 없으면 inventory에 `absent-allowed`로
-기록하고 비교를 계속한다. 파일이 존재하면 read-only로 읽어 Reference Model Contract와
-실제 input/CSV의 중복 필드를 대조한다. 충돌은 `needs-upstream-decision` 또는 적절한
-schema/provenance failure로 분류하며, 파일 부재만으로 `needs-reference-artifacts`를
-선택하지 않는다.
+Canonical naming, README, metadata, Abaqus version/provenance, duplicated units/coordinates/
+step-frame fields와 reference CSV schema version은 기본 gate가 아니다.

-## 비교 대상
+Missing, extra, duplicate 또는 nonfinite required row는 tolerance 전에 실패한다. Row order
+alone으로 대응하지 않는다. FESA/Reference 값을 zero-clamp하거나 tolerance에 맞게 보정하지
+않는다.

+## 보고 항목

-선택 Abaqus reference CSV:
- `reference/<model-id>/<model-id>_strains.csv`: strain이 acceptance criteria에 포함된 경우
- `reference/<model-id>/<model-id>_energy_or_residual.csv`: energy, residual, convergence quantity가 acceptance criteria에 포함된 경우
- `reference/<model-id>/<model-id>_<quantity>.csv`: feature-specific quantity가 acceptance criteria에 포함된 경우
+각 blocking 또는 warning-only quantity에 대해 다음을 보고한다.
+
+- exact input and CSV path
+- FESA HDF5 dataset
+- source ID/component mapping
+- compared, missing, extra, duplicate, nonfinite row counts
+- max absolute and relative error
+- RMS and norm error when required
+- worst source ID/component
+- pass, fail, or warning

 ## Failure Classification

- `missing-reference-artifact`: required Abaqus reference CSV file 또는 provenance가 없다.
- `missing-solver-output`: generated solver `results.h5` 또는 comparison command가 없다.
- `schema-mismatch`: FESA HDF5 또는 reference CSV row schema가 다르다.
- `id-mismatch`: node id, element id, step/frame, integration point, component matching이 실패했다.
- `unit-or-coordinate-mismatch`: units 또는 coordinate system이 비교 가능하지 않다.
- `tolerance-failure`: schema와 matching은 유효하지만 error가 tolerance를 초과했다.
- `nonfinite-result`: NaN 또는 infinite value가 발견됐다.
- `upstream-contract`: tolerance, schema, units, output location, ID matching policy가 누락 또는 충돌한다.
- `environment`: 로컬 실행 환경 문제로 비교가 불가능하다.
+- `missing-reference-artifact`: declared input or required CSV missing
+- `missing-solver-output`: `results.h5` or comparison command missing
+- `schema-mismatch`: required source ID/component columns unavailable
+- `id-mismatch`: required source row sets do not match
+- `tolerance-failure`: blocking value exceeds approved tolerance
+- `nonfinite-result`: required FESA or reference value is not finite
+- `upstream-contract`: quantity, HDF5 projection, mapping, or tolerance missing/contradictory
+- `environment`: local comparison cannot run
