Known Limitations + +1. 입력은 assembly-level `TYPE=ELEMENT` surface와 uniform `DSLOAD P`의 승인 subset뿐이다. + `*DLOAD`, `P n`, `PNU`, `HP`, `VP`, `SP`, `TRVEC`, `TRSHR`, nonuniform/user pressure, + `AMPLITUDE`, `FOLLOWER`, `OP`, `REF NODE`, `*INCLUDE`와 승인되지 않은 parameter는 지원하지 않는다. +2. Surface는 single-sided `SPOS|SNEG` four-node `S4`/`S4R`만 지원한다. Node/edge/double-sided, + analytical/contact surface, part-level surface, implicit/mixed-instance ELSET, transformed instance, + S3/S8/solid/continuum-shell/membrane/beam/rigid element는 범위 밖이다. +3. 단일 linear static 또는 단일 approved `NLGEOM=YES` full-Newton static step만 지원한다. + Dynamics, thermal, contact, buckling perturbation, cavity/pipe pressure와 multiple-step propagation은 제외된다. +4. 기존 linear isotropic elastic MITC4 material/section만 사용한다. Material nonlinearity, + composite/hyperelastic/plastic section, surface offset, thickness-face arm/correction 및 pressure + distributed couple은 지원하지 않는다. +5. Pressure는 midsurface translational generalized force를 만든다. Rotational pressure entries는 + exact zero이며 physical global moment는 force arm으로 평가한다. Invalid/collapsed/folded current + surface는 `tau_J=1.0e-12` gate에서 fail-closed한다. +6. Authoritative output은 기존 `_results.h5`뿐이며 surface/load 또는 pressure-only dataset은 + 추가되지 않는다. CSV는 product output이 아니다. +7. Stored external case는 `S4`, `SPOS`, positive `P=1e6`, `NLGEOM=YES` nonlinear displacement만 + 직접 검증한다. `S4R`, `SNEG`, negative/zero pressure, linear path, objectivity와 tangent는 + passing blocking internal tests로 보완되며 별도 external reference case는 없다. +8. `UR1/UR2/UR3` external comparison은 contract상 `warning-only`다. 이번 evidence에서는 모두 + 통과했지만 향후 warning-only mismatch는 blocking U verdict를 바꾸지 않는다. +9. Reaction CSV는 `review-only`, stress CSV는 `excluded`다. Local reaction distribution이나 + stress agreement을 external acceptance로 주장하지 않으며 internal residual/equilibrium gate를 사용한다. +10. 직접 적용 가능한 public S4/S4R follower-pressure benchmark가 없다는 연구 한계가 있다. + Analytical/kernel/solution tests와 exact stored case로 보완했으며 실험 validation을 주장하지 않는다. +11. FESA는 독립 solver다. Abaqus를 포함한 다른 solver의 내부 formulation, quadrature, + stabilization, tangent 또는 result-generation equivalence를 주장하지 않는다. + +Deferred must requirement, unresolved defect, accepted blocking risk 또는 release-blocking open item은 없다. + +## 7. Release Notes Draft + +### 사용자-facing 요약 + +FESA는 이제 승인된 Abaqus `.inp` subset에서 assembly named element surface의 `S4`/`S4R` +`SPOS` 또는 `SNEG` 면에 uniform `*DSLOAD P`를 적용할 수 있다. Linear static에서는 reference +surface를, `NLGEOM=YES` nonlinear static에서는 current surface follower force와 consistent +external tangent를 사용한다. Pressure는 기존 full-space load, reaction/free residual, +global equilibrium 및 HDF5 result lifecycle에 통합된다. + +### 검증 범위 + +- MSVC x64 Debug full CTest `362/362 PASS`, focused feature tests `64/64 PASS`. +- Exact stored nonlinear case에서 factor-one U blocking `2187/2187`, UR warning-only + `2187/2187` rows pass. +- Factor-one normalized global force/moment balance는 각각 `6.758e-14`, `3.725e-14`로 + 승인 gate `1e-8`을 통과했다. +- S4R, side/sign reversal, linear reference pressure, current-area objectivity, external tangent와 + invalid geometry는 독립 internal analytical/FD/fail-closed tests로 검증했다. + +### 주요 제한 및 사용 주의 + +이 release는 single-step linear 또는 approved nonlinear static, four-node S4/S4R, existing +linear-isotropic MITC4 section과 uniform single-sided pressure만 지원한다. `*DLOAD`, nonuniform +pressure, amplitude, node/edge/contact/double-sided surface, 다른 element/procedure/material 및 +surface offset/thickness correction은 지원하지 않는다. Model-consistent unit system을 사용해야 +하며 invalid current surface geometry는 fail-closed한다. UR은 warning-only이고 reaction/stress +CSV는 external verdict 대상이 아니다. Abaqus 내부 동등성이나 실험 validation은 주장하지 않는다. + +### Artifact paths + +- Runtime authoritative output: input lexical sibling `_results.h5` +- Required reference input: `reference/shellNL-meshfine-pressure/shellNL-meshfine-pressure.inp` +- Required comparison CSV: `reference/shellNL-meshfine-pressure/shellNL-meshfine-pressure displacements.csv` +- Release record: `docs/shell-surface-pressure-load/release.md` + +## 8. Release Verdict + +**Verdict: `ready-for-release`.** + +필수 upstream gate, full build/test, blocking reference comparison과 physics evaluation이 모두 +통과했다. Must requirement `24/24`가 release scope, acceptance criterion, implementation/test +또는 applicable reference evidence와 최종 disposition에 연결되고, known limitations가 +release notes에 포함되었다. Missing/failed/stale required evidence, unresolved defect, +missing comparison file, tolerance conflict 또는 physics blocker는 없다. + +이 verdict는 FESA 내부 feature delivery closure recommendation이며 외부 release 행위를 +승인하지 않는다. + +## 9. Handoff Recommendation + +Coordinator Agent는 Gate 8을 `passed`로 기록하고 `shell-surface-pressure-load` workflow를 +내부적으로 closure하는 것을 권고한다. 추가 Correction, Implementation, Physics Evaluation +또는 upstream decision return은 필요하지 않다. Publish, deploy, package, tag, merge, commit, +push 또는 external release는 별도 명시적 권한 없이는 수행하지 않는다. + +## 10. No-Change Assertion + +Release Agent는 이 감사에서 `docs/shell-surface-pressure-load/release.md`만 생성했다. Source, +public/private header, test, CMake, build/Harness configuration, phase files, upstream feature +documents/reports, `coordination.md`, reference input/CSV, generated HDF5/log, +`docs/TOLERANCE.md` 및 tolerance policy는 수정하지 않았다. Abaqus, Nastran 또는 다른 +reference solver를 실행하지 않았고 build, CTest, Harness 또는 FESA CLI를 재실행하지 않았다. + +## 11. Open Issues + +- Missing evidence: 없음. +- Contradictory upstream verdict/status/value: 없음. Archival pre-gate metadata와 compact + trace shorthand는 Coordinator 승인 및 actual passing evidence로 교차 확인되었다. +- Unresolved defects or failed corrections: 없음. Harness duplicate-verification timeout correction은 + 이후 automatic Stop full `362/362 PASS`로 해소되었다. +- Missing declared comparison files or mappings: 없음. +- Release documentation gap: 없음. +- Blockers: 없음.
