작업

1. MITC4-STATE-001..003을 먼저 작성한다.
2. Additive shell record types를 정의한다: stable element, GP1..GP4 natural location, local 3x3 frame, eight generalized strain/resultant, three section positions의 [S11,S22,S12].
3. AnalysisState에 shell rows, physical strain energy, six equilibrium components, three normalized verification metrics를 candidate-owned storage로 추가한다.
4. Validated candidate가 완성된 뒤에만 state로 commit하며 invalid/nonfinite/ inventory mismatch가 기존 state를 바꾸지 않게 한다.
5. Nonlinear director history, iteration, velocity, acceleration을 할당하지 않는다.

ctest --test-dir .harness/build -C Debug -R "AnalysisState|DomainModel" --output-on-failure
cmake --build .harness/build --config Debug
ctest --test-dir .harness/build -C Debug --show-only=json-v1

검증 및 상태 갱신

RED/VERIFY evidence를 기록하고 현재 Step 상태 payload만 갱신한다.

금지사항

• Element calculation, ResultRecovery orchestration, HDF5를 구현하지 마라.
• Nonlinear/dynamic state나 drilling-specific row를 추가하지 마라.
• 직접 commit/hook 실행 또는 reference/upstream 변경을 하지 마라.
