-## 2. Release Scope
-
-| 구분 | 포함 범위 |
-| --- | --- |
-| 기능 | Assembly-level `*SURFACE, TYPE=ELEMENT, NAME=<name>`의 `SPOS|SNEG` member에 step-level `*DSLOAD`의 uniform finite scalar `P`를 적용 |
-| analysis type | 단일 linear static의 reference-configuration pressure, 단일 `NLGEOM=YES` full-Newton nonlinear static의 current-configuration follower pressure와 external tangent |
-| elements | Source type과 label을 보존하는 four-node `S4`, `S4R`; 기존 FESA MITC4 선택 |
-| materials/sections | 기존 linear isotropic elastic MITC4 shell material/section; 이 기능은 material 범위를 확장하지 않음 |
-| load semantics | Positive `P`는 selected surface normal 반대 방향, negative `P`는 방향 반전, load factor는 정확히 한 번 적용 |
-| assembly/physics | Stable full-DOF external load/tangent assembly, free/constrained projection, reaction/free residual, current-arm global force/moment equilibrium, deterministic ordering |
-| input subset | Direct `<instance>.<element-label>` member와 explicit `INSTANCE=`에 결속된 flat assembly ELSET member; case-insensitive lookup과 stable raw/source identity |
-| result scope | 기존 schema `0`/`1` HDF5의 displacement, generalized force/residual, reaction, global equilibrium 및 기존 MITC4 result chain; 새 pressure-only dataset 없음 |
-| reference scope | Exact stored nonlinear S4/SPOS/positive-`P` case의 factor-one nodal `U1/U2/U3` blocking, `UR1/UR2/UR3` warning-only comparison |
-| artifact scope | Runtime authoritative artifact는 `<stem>_results.h5`; CSV는 external reference/debug evidence이며 FESA product output이 아님 |
-
-Release 범위에서 제외되는 핵심 항목은 `*DLOAD`, nonuniform/field/user pressure,
-node/edge/double-sided/contact surface, S4/S4R 이외 element, material nonlinearity, dynamics,
-thermal/contact/buckling, multiple-step propagation, surface offset/thickness-side correction,
-pressure-only result quantity 및 다른 solver 내부 알고리즘과의 동등성 주장이다.

-## 3. Gate Evidence Inventory
-
-| Gate evidence | feature/status 감사 결과 | release disposition |
-| --- | --- | --- |
-| `requirements.md` | 동일 feature, must `001`–`024`; 초기 `draft-for-coordinator-gate-review` label을 유지하지만 Coordinator Gate 1 통과 및 이후 전 단계의 binding baseline으로 사용됨 | pass |
-| `research.md` | 동일 feature; 초기 gate-review label을 유지하며 formulation/reference 범위와 non-equivalence 경계가 후속 문서에 반영됨 | pass |

-변경은 `coordination.md`와 `physics-evaluation.md`뿐이다. 평가 후 source, test, CMake,
-reference artifact 또는 tolerance 변경은 없다. 초기 문서의 archival status label과
-`implementation-report.md`의 compact requirement/evidence shorthand는 Coordinator 승인,
-`implementation-plan.md` §11, 실제 named-suite inventory, reference 및 physics evidence로
-교차 확인했다. Release acceptance를 바꾸는 미해결 상태·범위·수치 모순은 없다.

-
-### 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.
