+
+The full CTest output reported no failed-test inventory. The build emitted no compiler/linker
+output beyond `ninja: no work to do.`; the build tree audit found no new `warning C####` or
+`: warning:` record. The only diagnostic setup issue was that standalone HDF5 inspection tools
+need Intel `libmmd.dll` on `PATH`; this did not affect the staged test executables, CMake build, or
+CTest and is not a product failure.
+
+## Results and handoff
+
+The selected `.harness/config.json` preset was used throughout. All commands were run from the
+repository root in an x64 VsDevCmd environment. The final status is
+`pass-for-physics-evaluation`; no Harness Python command was required because this Step did not
+change Python, hooks, or agent configuration.
+
+This Step changed documentation and its own phase status only. It did not modify C++ production,
+tests, CMake, Harness configuration, tolerance, reference artifacts, or output data. The immutable
+reference artifact audit before and after comparison was identical; see `reference-comparison.md`.

 ## 1. Metadata and Feature Scope
 
 - feature_id: `nonlinear-static-newton-raphson`
-- workflow_state: `needs-implementation`
+- workflow_state: `completed`
 - owner_agent: `coordinator-agent`
 - request_date: `2026-08-18`
-- last_updated: `2026-08-24` (Harness attempt 1 timed out before Step 0 evidence; Step 0 retry dispatch package ready)
+- last_updated: `2026-08-28` (STAGE8-RELEASE-001 return audited; eight-stage workflow completed)
 - process_classification: `architectural`
 - requested_capability: Newton–Raphson 방법을 사용하는 새 nonlinear static analysis procedure
 - proposed_scope_boundary: 첫 release는 initial configuration 기준 Total Lagrangian, materially linear + geometrically nonlinear MITC4로 제한한다. 요구조건 인터뷰와 8단계 evidence gate를 먼저 완료하며, 승인 전에는 상세 수치·I/O·구현 범위를 확정하거나 기존 linear-static lifecycle을 변경하지 않는다.
 - naming_note: 사용자 표현 `Newton-Rhapson`은 표준 명칭 `Newton–Raphson`으로 정규화했다.
-- current_goal: Retry the user-authorized no-push Harness execution of materialized phase `nonlinear-static-newton-raphson`; Step 0 `cli-output-lease-and-derived-names` remains the only current Step after attempt 1 failed before Step evidence.
-- constraints: 승인된 Stage 1-5 hashes, physics/scope/tolerance/authoritative output/public compatibility, `rho_M <= 1e-12`, fixed-global source identity, no drilling load channel과 Stage 6 materialization evidence를 보존한다. Retry `python scripts/execute.py nonlinear-static-newton-raphson` without `--push`; do not run `--push`, force-push, or use `danger-full-access`. Attempt 1 failure is classified as `harness-uncaught-step-codex-timeout-no-retry` attempt 1; if the same classification reaches attempt 2, stop automatic rework and route to `needs-user-decision` or `blocked`. `scripts/execute.py` owns branch, pending-Step selection, retry, timestamps, commits, advancement and top-level phase status. Each Implementation Agent session owns only the Executor-selected current `stepN.md` and must perform `RED -> observed failure -> minimal GREEN -> VERIFY`, updating only that Step status plus summary/error/blocked payload. Do not advance Physics/Release until `implementation-report.md`, `build-test.md`, `reference-comparison.md` and passing implementation evidence exist. Stress CSVs are optional inspection/order evidence only with no comparison projection; `RM3` is excluded; shellNL `U` is blocking, `UR` warning-only, constrained `RF` families and physical spatial `RM1/RM2` are blocking; exact source-ID prechecks and `docs/TOLERANCE.md` are preserved. Reference input/CSV 생성·수정·rename·정규화와 Abaqus/Nastran/reference solver 실행을 금지한다.
+- current_goal: Stage 8 `ready-for-release` is audited and the eight-stage workflow is closed. Root retains the user's requested final commit/push; no external release action is authorized.
+- constraints: 승인된 physics/scope/tolerance/authoritative output/public compatibility, `rho_M <= 1e-12`, fixed-global source identity, no drilling load channel, thresholds `1e-2`/typed absolute `1e-3`, four-channel AND, Full Newton, fixed stepping, no line search, 100-iteration limit, `docs/TOLERANCE.md`, reference artifact filenames/hashes, stress optional inspection and `RM3` exclusion을 유지한다. USER-DECISION-004 option 1 keeps local nodal `RF1/RF2/RF3` and physical spatial `RM1/RM2` review-only/nonblocking, with blocking factor-one global applied-plus-reaction resultant force `[3]`, global resultant moment `[3]` and accepted free-DOF residual gates/evidence; global resultant semantics are global origin `[0,0,0]`, current force arms and spatial physical nodal moments. USER-DECISION-006 supersedes/retire prior moment-only `1e-9` and all `fesa.env`/runtime-config discussion: do not add `fesa.env`, config parsing, runtime API, or product behavior. Current authoritative decision fixes both normalized factor-one global FORCE and MOMENT balance gates at `<=1e-8` while preserving exact formulas, sum-of-contribution scales, zero-scale rule, quantities/source identity, blocking/review/warning dispositions, NSNR-069 free-residual gates, HDF5 schema, reference artifacts and `docs/TOLERANCE.md` separation. Sequential reapproval is delegated to Coordinator without intermediate user approval through Stage 4 Numerical/reference, Stage 5 I/O and Stage 6 Implementation Planning materialization; Steps `11` and `12` are completed under the approved Codex CLI `0.150.1`/Ninja/MSVC envelope. Stage 8 may create only `release.md`; no push, no `danger-full-access`, no reference mutation/solver, no source/tests/CMake/upstream/tolerance edit, and no publish/deploy/package/tag/external release. Any required contract change beyond the fixed `1e-8` global balance threshold stops as blocker.
 - repository_audit: 기존 worktree에는 `.codex/agents/*.toml`과 `AGENTS.md`의 사용자 변경이 있으며 이를 보존한다.

Root evidence also reports workspace-write smoke pass `HARNESS_SMOKE_OK` in `20.4s`, MSVC baseline build pass and CTest `214/214`; the Python baseline `xhigh` vs `extra high` failure is pre-existing/unrelated.

-  - If all Steps complete, Stage 6 evidence docs: `docs/nonlinear-static-newton-raphson/implementation-report.md`, `docs/nonlinear-static-newton-raphson/build-test.md`, `docs/nonlinear-static-newton-raphson/reference-comparison.md`.
-- acceptance_gate: Stage 6 can pass only after the materialized phase completes and Coordinator audits implementation-report, build-test, reference-comparison, full MSVC x64 Debug build/CTest, blocking reference comparison and no forbidden reference/upstream/tolerance mutation. Attempt 1 is a clear first `harness` failure, so the next bounded dispatch remains Implementation/Harness retry.
-- stop_condition: Run only the no-push Harness executor for this phase. Do not dispatch Correction Agent for this first clear harness failure. If `harness-uncaught-step-codex-timeout-no-retry` recurs and reaches attempt 2, stop automatic rework and set workflow to `needs-user-decision` or `blocked`. Do not dispatch Physics Evaluation or Release. Do not run Abaqus/Nastran/reference solvers or generate/modify reference CSVs. Do not manually bypass Executor ownership of branch, pending selection, retry, timestamps, commits or advancement.
-- missing_evidence: Successful Step 0 Harness/Implementation return with RED/observed failure/minimal GREEN/VERIFY evidence and Executor-managed Step status, or a new classified failure return from `scripts/execute.py nonlinear-static-newton-raphson`.
+- current_dispatch: `none`

+- acceptance_gate: All eight stages passed and `release.md` recommends `ready-for-release`; Coordinator closure is recorded.

 ### Latest Sub-Agent Return
 
-- target_sub_agent: `implementation-agent` via Harness Executor
+- target_sub_agent: `release-agent`
 - output_paths:
-  - 없음: attempt 1 failed before Step evidence; `step0-output.json`, `implementation-report.md`, `build-test.md`, and `reference-comparison.md` were not produced.
-- status: `failed-before-step-evidence` (Harness uncaught timeout); Coordinator classification `needs-implementation-retry`
+  - `docs/nonlinear-static-newton-raphson/release.md`
+- status: owner `ready-for-release`; Coordinator decision `passed`
 - evidence_summary:
-  - Root reported no-push execution attempt 1 on an isolated branch/worktree: `python scripts/execute.py nonlinear-static-newton-raphson`.
-  - During Step 0 dispatch, `codex exec --json --sandbox workspace-write ...` remained active without source/test edits and timed out at `1800.7s`.
-  - `scripts/execute.py::_invoke_codex` raised uncaught `subprocess.TimeoutExpired`, so Executor did not produce `step0-output.json`, did not enter `MAX_RETRIES`, and Step 0 remains pending with no implementation evidence.
-  - Workspace-write smoke passed with `HARNESS_SMOKE_OK` in `20.4s`; root therefore classified sandbox helper/auth as functional and `danger-full-access` as unjustified.
-  - MSVC baseline build passed and CTest passed `214/214`; Python baseline has a pre-existing unrelated contract failure in HEAD `41816c8` (`xhigh` actual vs `extra high` expected).
-  - Coordinator records normalized failure classification `harness-uncaught-step-codex-timeout-no-retry`: attempt 1. Because this is the first clear harness failure, the next bounded dispatch remains `implementation-agent` via no-push Harness retry; `correction-agent` is not selected.
+  - `release.md` SHA-256 `0DA80387B137DAA7629D4B0A0C1E5442F90E17F142345379669B2E1D1962E1D1`; all 11 required sections and `ready-for-release` verdict are present.
+  - Gate inventory hashes match current Stage 1..7 files; full CTest `302/302`, reference `9/9`, `pass-for-physics-evaluation`, and `pass-for-release-agent` are recorded.
+  - Requirement/release sets are exactly 24/24 unique IDs, missing/extra/duplicate `0`, all `included-pass` with acceptance, test or reference evidence and release disposition.
+  - Known limitations and Release Notes include local RF/RM review-only, UR warning-only, `RM3`/stress exclusion, malformed optional stress row, weak stored nonlinear response, MITC4 locking risk and no external-solver equivalence claim.
+  - Requirements draft/pending metadata and missing literal reference-comparison feature_id are transparent nonblocking documentation issues tied to authoritative exact path/hash/approval evidence; upstream files were not edited.
 - blockers:
-  - 없음.
-- self_audit_findings: Coordinator recorded root execution evidence only, verified the local phase index still lists Step 0 as `pending`, did not run Harness/build/tests, and changed only `coordination.md`.
-- return_contract_check: status, evidence summary, blockers, failed-output absence and retry dispatch decision are present.
-- acceptance_evidence_check: Stage 6 remains `in-progress`; no Stage 6 pass evidence exists.
+  - 없음
+- self_audit_findings: Release owner created only `release.md`; no source/test/CMake/Harness/upstream/reference/tolerance mutation, build/test/reference solver, publish/deploy/package/tag/external release, commit or push.
+- return_contract_check: Output path, `ready-for-release`, gate/traceability/validation/limitation evidence, blockers, SHA-256, no-change assertion and closure recommendation are complete; Coordinator audit passed.
+- acceptance_evidence_check: Stage 8 passes and Coordinator closes the workflow as `completed`; this does not authorize an external release action.
+
+### USER-DECISION-004 Selected Path
+
+- selected: User explicitly approved option 1 on `2026-08-26`.
+- meaning: exact local nodal `RF1/RF2/RF3` and physical spatial `RM1/RM2` rows remain deterministic source-key/schema/finite/inventory/error-reporting evidence but become review-only/nonblocking; `RM3` remains excluded.
+- blocking evidence: factor-one global resultant force `[3]`, factor-one global resultant moment `[3]`, and accepted free-DOF residual gates/evidence. Resultant moment uses the existing I/O global-equilibrium contract: global origin `[0,0,0]`, current force arms and spatial physical nodal moments.
+- unchanged: displacement comparison remains blocking, `UR1/UR2/UR3` remains warning-only, stress CSVs remain optional inspection/no comparison projection, `docs/TOLERANCE.md` applies where external comparison remains, and exact source-ID prechecks are preserved.
+- prohibited: no averaging/collapse/zero clamp, no tolerance relaxation, no comparator weakening, no reference artifact edit, and no Abaqus S4 internal-equivalence claim.
+- re-approval path: Stage 1 requirements, Stage 4 Numerical/reference and Stage 5 I/O are re-approved. Stage 6 implementation-planning revision draft is returned, Coordinator-audited, user-approved and materialized by MATERIALIZATION-003. DECISION-042 now supplies the separate explicit Step 11 Harness/Implementation request. Stage 3 formulation has no immediate dispatch because current §11.4 and §13.4 already define full residual/reactions and global resultant identities.
+
+`MESH-REFINEMENT-SPIKE-001` remains diagnostic evidence that option 3 is not met by the current Abaqus S4 coarse/fine pair. `TRANSLATION-REPORT-001` remains translation-only diagnostic evidence and does not authorize final reference-model, tolerance, comparator, HDF5 schema, implementation, Harness, Step 12, Physics or Release changes.

Proof: shellNL has no external rotational generalized force, so approved `D_M=max(||f_int||inf,||f_ext||inf)` gives `eta_M=1` for every nonzero rotational residual; focused CTest #288 reproduced the failure and 100/100 log records have numerator=denominator, relative branch, pass=0. | `needs-user-decision` | USER-DECISION-003: choose a residual-moment convergence contract path before requirements/formulation/numerical-review/io/planning rework or stop the feature |

Coordinator preflight verified isolated linked worktree, branch `feat-nonlinear-static-newton-raphson`, HEAD `65b56b1`, Step 11 `pending` with historical `started_at`, Step 12 `pending`, Codex CLI `0.149.1`, approved `windows-msvc-ninja-debug` preset/config, runner `--disable unified_exec`, and approved dirty state with preserved comparator files. | `needs-implementation` | Launch no-push Harness Executor under DECISION-038/039 envelope; await Step 11 return; no `danger-full-access`, push, reference mutation, reference solver, Step 12, Physics or Release |
+| 2026-08-25 | Step 11 reference-comparison return and REWORK-008 dispatch package | `needs-rework` | Harness exit `2`; Step 11 blocked; Step 12 pending; `step11-output.json` SHA-256 `0F3B876AF84398EB1D2C90335998115797054B012899DE27E4070A6F533EEF91`. Selector/control/log fix passed and factor-one HDF5 exists, but reference gate `15/16` failed on blocking reaction RMS. Additional read-only diagnosis shows deterministic key mapping and global equilibrium but local reaction redistribution mismatch already present in linear-limit reactions, so Correction must audit implementation-vs-upstream-contract before any production edit. | `needs-correction` | Root profile dispatch to `correction-agent` for REWORK-008 diagnostic; no tolerance/reference/HDF5 schema contract change, reference solver, reference mutation, `danger-full-access`, push, Step 12, Physics or Release |
+| 2026-08-25 | REWORK-008 upstream-contract return and USER-DECISION-004 gate | `blocked` | Correction returned `needs-upstream-decision`, classification `upstream-contract` / `reference-blocking-model-adequacy-conflict`, Section 13 SHA-256 `C8AC5A5015E5F9622E2964F514F2C06572F953B5244F006044DEDDF0F3D0A194`. It found no reaction computation/storage/mapping defect: residual→reaction→HDF5 mapping exact, constrained `phi=0`, global resultant matches, and local RF/RM mismatch already exists in FESA-linear versus Abaqus-linear while each solver NL≈linear. No forbidden files changed by correction; reference diff clean and HEAD unchanged. | `needs-user-decision` | USER-DECISION-004: choose local nodal reactions review-only with global equilibrium blocking, global resultant-only blocking, or independent formulation-appropriate local-reaction benchmark; do not dispatch further work before explicit choice |
+| 2026-08-25 | MESH-REFINEMENT-SPIKE-001 numerical-review dispatch | `in-progress` | User added untracked main-checkout `reference/shellNL-meshfine` artifacts and explicitly approved a spike design for USER-DECISION-004 option 3 candidate validation. Coordinator verified read-only hashes/rows and feature-worktree missing state, then recorded a bounded `numerical-review-agent` package for artifact/input-equivalence/row-identity readiness only. | `needs-user-decision` | Root profile dispatch to `numerical-review-agent`; no final option selection, reference solver, artifact mutation, tolerance/comparator/HDF5 schema/implementation/Harness/Step 12/Physics/Release change |
+| 2026-08-25 | MESH-REFINEMENT-SPIKE-001 diagnostic return and Coordinator audit | `passed` | Fine artifacts copied byte-identically; required displacement/reaction artifacts are valid, stress is optional inventory only with one malformed optional key. Existing executable run exited `0` and produced H5/log hashes. Translation/rotation pass common tolerance, but local RF/RM rows still fail per-row gates; inplane reaction worsens under refinement. Global resultants and free residuals are sound. The same Abaqus S4 coarse/fine pair is not an independent formulation-appropriate local-reaction benchmark. | `needs-user-decision` | Ask user to choose USER-DECISION-004; Coordinator recommends option 1 review-only local nodal rows plus blocking global equilibrium/resultants; no Harness/Step 11 rerun before approval |
+| 2026-08-26 | TRANSLATION-REPORT-001 focused reporting dispatch | `in-progress` | User approved bounded focused report design for `docs/nonlinear-static-newton-raphson/translation-displacement-comparison.md`: coarse/fine U1/U2/U3 translation-only comparison with exact artifact/HDF5 identity, source-key prechecks, `docs/TOLERANCE.md`, metrics, worst rows, mesh trend and exclusions. | `needs-user-decision` | Root profile dispatch to `implementation-agent`; only the focused report may be created; do not create canonical `reference-comparison.md`, run solver/Harness/reference solver, edit code/comparator/tolerance/reference artifacts, change USER-DECISION-004, or advance Step 11/12 |

Coordinator/root audit verified exact artifact hashes, coarse/fine U-key prechecks, `docs/TOLERANCE.md` pass metrics, explicit exclusions, diff check pass, tracked reference diff clean and canonical evidence docs absent. | `needs-user-decision` | Historical pre-decision state; superseded by USER-DECISION-004 option 1 entry below. No Step 11 rerun, Step 12, Physics or Release before required upstream re-approval |
+| 2026-08-26 | USER-DECISION-004 option 1 approval and requirements dispatch package | `in-progress` | User explicitly selected option 1. Coordinator recorded local nodal RF/RM as review-only/nonblocking, global resultant force/moment plus accepted free residual as blocking reaction/equilibrium evidence, verified Stage 3 formulation has no immediate semantic rework need because §11.4/§13.4 already define reactions/global resultants, and recorded the Stage 5/6 projection audit item for current-position/spatial-moment global equilibrium versus raw-residual implementation helper. | `needs-requirements` | Root profile dispatch to bounded `requirement-agent` for `requirements.md` only; after owner return, Coordinator audit and explicit user approval are required before Stage 4 |

Coordinator closed REAPPROVAL-008 and prepared bounded DRAFT ONLY `implementation-planning-agent` package requiring `fesa-cpp-msvc-tdd` plus project-local `harness`; the owner must audit existing Step 11+ plan/phase state and return a chat draft only. | `needs-implementation-plan` | Root profile dispatch to `implementation-planning-agent`; no planning-file materialization, Harness, build, CTest, solver, reference solver, source/test/CMake/reference/tolerance edit, commit or push before draft approval |
+| 2026-08-27 | REAPPROVAL-009 Planning draft return and Coordinator audit | `passed` | Planning Agent returned `draft-ready-for-user-review`, blockers none, no files changed/executed. Coordinator verified the draft is a minimal Step 11/12 revision: preserve Steps `0..10`, reset/rename only Step `11` after approval, keep Step `12` pending, cover AUDIT-001 current-arm/spatial-moment projections, no new HDF5 dataset/public header, internal/external tolerance separation, fine primary/coarse companion and approved Ninja/MSVC commands. | `needs-user-decision` | Ask user to approve or reject the Stage 6 revision draft; do not materialize planning files or run Harness until explicit approval |
+| 2026-08-27 | REAPPROVAL-009 draft approval and MATERIALIZATION-003 dispatch package | `in-progress` | User explicitly approved the Coordinator-audited 2-Step draft. Coordinator prepared materialization-only dispatch to `implementation-planning-agent`, required `fesa-cpp-msvc-tdd` plus project-local `harness`, fixed current input hashes and allowed only `implementation-plan.md`, `phases/index.json`, phase index, `step11.md` and `step12.md` as outputs. | `needs-implementation-plan` | Root profile dispatch to `implementation-planning-agent`; no Harness/build/CTest/solver/reference solver, code/tests/CMake/upstream/reference/tolerance edit, evidence-doc creation, commit or push |

Coordinator verified JSON parse, 24/24 requirements mapping, clean placeholder scan, scoped `git diff --check` pass, `NSNR-PROC-019` collision handling, Step `11` pending, Step `12` pending, Steps `0..10` preserved, canonical evidence docs absent, tracked reference diff clean, and no execution/commit/push. | `needs-implementation` | Await separate explicit no-push Step 11 Harness/Implementation request; do not run Harness automatically |
+| 2026-08-27 | Step 11 no-push Harness/Implementation execution approval | `in-progress` | User explicitly approved `Harness/Implementation 시작`. Coordinator verified current runner CLI takes slug `nonlinear-static-newton-raphson`, current phase has Step `11` pending and Step `12` pending, and prepared a no-push `implementation-agent` via Harness dispatch for Step `11` only under DECISION-038/039. Step `12` is outside this approval; current runner loops over pending steps, so root/Executor must enforce the one-step boundary or stop before Step `12`. | `needs-implementation` | Root may run `python scripts/execute.py nonlinear-static-newton-raphson` only under the recorded no-push Step 11 envelope; await Step `11` return |
+| 2026-08-27 | Step 11 execution recurrent runtime block | `blocked` | DECISION-042 Step11-only execution used the approved no-push envelope but timed out after `1800s`; `step11-output.json` SHA-256 `9FCBC5CE10E2C1B931EC16CADFADF7684C45FBB0B11D9A404922D607EB16706D`, exit `124`, stderr `Codex timed out after 1800 seconds.`, stdout nested command executions stuck `in_progress`. Retry was prevented by secondary CP949 `UnicodeEncodeError` printing `↻`. Read-only shell smokes under tested flag/env variants did not complete. Step `11` and Step `12` remain pending; no production/test/reference edits, commit or push. | `needs-user-decision` | No automatic correction dispatch; user must choose a runtime/runner route before any Step `11` rerun |
+| 2026-08-28 | USER-DECISION-005 option A and Step 11 runtime-smoke dispatch | `in-progress` | User approved option A: use official current Codex CLI `0.150.1` to restore the runtime/update path, prove same `workspace-write`/filtered WindowsApps PATH/`CODEX_HOME`/VsDevCmd/hooks/Terra-xhigh/`--disable unified_exec` envelope with a bounded nested shell smoke, then rerun only Step `11` no-push if the smoke passes. | `needs-implementation` | Root may perform the Codex `0.150.1` smoke preflight and, only on pass, launch Step `11` Harness/Implementation under the active dispatch; Step `12`, push, `danger-full-access`, reference solver/artifact mutation and manual hooks remain forbidden |
+| 2026-08-28 | USER-DECISION-005A smoke pass and Step 11 dispatch confirmation | `passed` | Root supplied smoke success evidence: Codex CLI `0.150.1`, app SHA-256 `CBD657DDFE151D1A6EBAD660BEFFDBD3265DC5AFF4B3A6095124D3E2F0156F2F`, doctor `20 ok/0 fail`, same-envelope smoke `93.621s`, nested exit `0`, command_execution completed, command exit `0`, output `CODEX_SHELL_SMOKE_OK`, stderr empty. Coordinator updated `BLOCKER-002` to smoke-passed and confirmed Step `11` dispatch. | `needs-implementation` | Historical smoke gate pass; superseded by the Step `11` blocked return below |

Current authoritative decision fixes both normalized factor-one global FORCE and MOMENT balance gates at `<=1e-8`; all formulas, sum-of-contribution scales, zero-scale rule, quantities/source identity, blocking/review/warning dispositions, NSNR-069, HDF5 schema, reference artifacts and `docs/TOLERANCE.md` separation are preserved. User delegated Stage 4/5/6 reapproval and Step `11` completion without intermediate approval waits, bounded to this threshold-only change. | `needs-numerical-review` | Root/profile dispatch to `numerical-review-agent` with `fesa-numerical-review`; allowed outputs only `numerical-review.md` and `reference-model.md`; do not start Stage 5, planning, Harness, Step `11` retry, Step `12`, reference solver, push or `danger-full-access` before owner return and Coordinator audit |

+# Nonlinear Static Newton-Raphson Correction Report
+
+## 1. Metadata
+
+| key | value |
+| --- | --- |
+| feature_id | `nonlinear-static-newton-raphson` |
+| source failure report | `docs/nonlinear-static-newton-raphson/coordination.md`; `phases/nonlinear-static-newton-raphson/step0-output.json`; `phases/nonlinear-static-newton-raphson/step1-output.json` |

+
+`implementation-report.md`, `build-test.md`, `reference-comparison.md`는 아직 생성되지 않았으므로 현재 Coordinator failure evidence와 Executor의 `step0-output.json` 및 `step1-output.json`을 source failure report로 사용했다.
+
+Sections 2-6의 Codex `0.147.0` 내용은 initial correction history이고 Sections 7-9는 REWORK-004 history다. Section 10은 FileTracker diagnosis history이고 Sections 11-13은 이전 correction history다. Current correction과 status는 Section 14가 supersede한다.
+
+## 2. Failure Triage
+
+- classification: `harness`
+- normalized classification: `harness-nested-codex-windows-shell-tool-execution-hang`
+- first failed command:
+
+  ```powershell
+  codex exec --json --model gpt-5.6-terra --config 'model_reasoning_effort="xhigh"' --sandbox workspace-write --dangerously-bypass-hook-trust --cd C:\git\FESADev\.worktrees\nonlinear-static-newton-raphson -
+  ```
+
+- failed target or test: nested shell smoke `cmd.exe /d /c echo CODEX_SHELL_SMOKE_OK`
+- evidence tail: baseline diagnostic는 45초 안에 종료되지 않았다. JSONL에는 `item.started`, `type=command_execution`, `status=in_progress`가 기록됐지만 대응하는 completion event와 `CODEX_SHELL_SMOKE_OK` 출력이 없었다. 진단 root PID `11292`와 관찰된 descendant PID tree를 `taskkill /PID 11292 /T /F`로 종료한 뒤 `remainingPids=[]`를 확인했다.
+- historical evidence: `step0-output.json`도 exit code `124`, stderr `Codex timed out after 1800 seconds.`를 기록했고 `Get-Date`, `cmd.exe /d /c echo test`, `exit 0` 등의 nested command가 `status=in_progress`에 머물렀다.
+
+## 3. Root Cause Summary
+
+실패 경계는 repaired Python Executor의 timeout/retry 처리나 FESA C++ 구현이 아니라 local `codex-cli 0.147.0`의 nested command execution runtime이다. 같은 worktree에서 direct PowerShell과 `cmd.exe`는 정상 실행되고, focused Harness Python test도 통과하며, runner-equivalent Codex baseline만 nested shell completion을 반환하지 않았다.
+
+Local CLI help는 `--disable <FEATURE>`와 `--enable <FEATURE>`를 문서화하고, `codex features list`는 `code_mode_host`를 `stable true`, `shell_tool`을 `stable true`, `unified_exec`를 `stable false`, `hooks`를 `stable true`로 보고했다. 다음 좁은 가설을 한 변수씩 검사했다.
+
+| variant | result | command completion evidence |
+| --- | --- | --- |
+| baseline | 45.318초 timeout 후 exact PID tree cleanup | `item.started/status=in_progress`; completion 및 echo output 없음 |
+| `--disable code_mode_host` | exit `0`, 33.322초 | shell 미실행; stderr `code-mode host is disabled`; completion event 없음 |
+| `--enable unified_exec` | 45.299초 timeout 후 exact PID tree cleanup | completion event 및 echo output 없음 |
+| `--disable code_mode_host --enable unified_exec` | exit `0`, 25.922초 | shell 미실행; 동일한 fail-closed host-disabled error |
+
+따라서 `--disable code_mode_host`는 shell execution을 복구하지 않고 tool host를 fail-closed로 제거한다. `unified_exec`도 단독 또는 조합에서 실제 shell completion을 만들지 못했다. Codex 내부 결함의 더 세부 원인은 repository evidence로 확정할 수 없으며, 안전한 documented runner flag workaround는 입증되지 않았다. 이는 implementation defect, test defect 또는 CMake registration issue가 아니라 external Codex runtime blocker다.
+
+## 4. Correction Scope
+
+- changed source files: `scripts/execute.py` (`codex exec` argv에 adjacent `--disable`, `unified_exec` 추가)
+- changed header files: 없음
+- changed test files: `tests/test_execute.py` (Implementation Agent command contract regression assertion 추가)
+- changed CMake files: 없음
+- changed report files: `docs/nonlinear-static-newton-raphson/corrections.md`
+- excluded upstream contract files: `requirements.md`, `research.md`, `formulation.md`, `numerical-review.md`, `reference-model.md`, `io.md`, `implementation-plan.md`
+- excluded artifacts/policies: phase definition/index, production C++, reference inputs/CSV, `docs/TOLERANCE.md`
+
+초기 correction cycle에서는 safe workaround가 입증되지 않아 runner/test를 변경하지 않았다. 이후 user/root가 Codex `0.149.1`의 bounded smoke로 `--disable unified_exec` runtime envelope를 입증했고, REWORK-004에서 그 pair만 TDD로 추가했다. 기존 Harness-repair 변경과 다른 owner의 dirty-worktree 변경은 그대로 보존했다.
+
+## 5. Verification Evidence
+
+| purpose | command | result |
+| --- | --- | --- |
+| installed CLI | `codex --version` | exit `0`; `codex-cli 0.147.0` |
+| documented options | `codex exec --help`; `codex features list` | exit `0`; `--enable/--disable`, `code_mode_host`, `unified_exec`, `shell_tool`, `hooks` 확인 |
+| targeted reproduction | runner-equivalent `codex exec ... --sandbox workspace-write ...` + one echo tool request | 45초 timeout; command started, completion/output 없음; exact tree cleanup 후 remaining PID 0 |
+| focused Harness Python | `uv run --with pytest python -m pytest -v -rs tests/test_execute.py` | exit `0`; 10 passed |
+| full Harness Python | `uv run --with pytest python -m pytest -v -rs` | exit `1`; 23 passed, 1 failed |
+| MSVC Debug build | `cmake --build .harness/build --config Debug` | exit `0`; solver/CLI/unit/integration/reference targets built |
+| CTest discovery | `ctest --test-dir .harness/build -C Debug --show-only=json-v1` | exit `0`; 214 tests discovered |
+| full CTest | `ctest --test-dir .harness/build -C Debug --output-on-failure` | exit `0`; 214/214 passed |
+
+`.harness/config.json`은 없었다. Existing `.harness/build/CMakeCache.txt`는 `Visual Studio 18 2026`, `x64`, approved local GoogleTest/MKL/TBB/HDF5 paths를 사용하므로 Harness auto-detected build tree를 재사용했다.
+
+Full Python failure는 pre-existing out-of-scope contract mismatch다: `test_agent_toml_and_limited_skill_yaml_schemas_are_parseable`가 actual `xhigh`와 expected `extra high`를 비교한다. Dispatch 지시에 따라 이 test, `AGENTS.md`, agent profile을 변경하지 않았다.
+
+Stop hook은 Harness Step 실행을 금지한 이번 correction session에서 별도 Codex Step 종료 evidence를 생성하지 않았다. Hook entry point의 수동 실행은 project contract가 금지하므로 대신 config-resolved full MSVC build와 full CTest를 직접 실행해 결과를 위에 기록했다.
+
+## 6. Traceability
+
+| requirement id | task id | test id | failing command | corrected file | acceptance criterion |
+| --- | --- | --- | --- | --- | --- |
+| `FESA-REQ-NSNR-083` | Step 0 `cli-output-lease-and-derived-names` | `CORR-HARNESS-SMOKE-001` | runner-equivalent `codex exec` invoking `cmd.exe /d /c echo CODEX_SHELL_SMOKE_OK` | 없음 | workspace-write, hooks, `gpt-5.6-terra`/`xhigh`, no-push, no `danger-full-access`를 유지한 실제 shell completion과 exact echo output; 실패 |
+| `FESA-REQ-NSNR-083` | Step 0 `cli-output-lease-and-derived-names` | `CORR-HARNESS-SMOKE-002` | same smoke with `--disable code_mode_host` | 없음 | shell completion 복구; 실패 (`code-mode host is disabled`) |
+
+Runner correction acceptance criterion이 충족되지 않았으므로 Implementation Step 0의 `NSNR-CLI-*` RED/GREEN은 시작되지 않았고 Step 0 status는 `pending`으로 유지된다.
+
+## 7. Handoff Recommendation
+
+- recommendation: Coordinator Agent를 통해 Implementation Agent에 `needs-implementation-rerun` 요청.
+- corrected runner contract: nested command는 `codex exec --disable unified_exec --json ...` 순서로 실행된다.
+- preserved execution contract: Coordinator가 관리하는 rerun launch environment는 Codex `0.149.1`, aligned `CODEX_HOME`, approved WindowsApps PATH filtering, `workspace-write`, project hooks, `gpt-5.6-terra`, `xhigh`, no-push, no `danger-full-access`를 유지해야 한다.
+- scope boundary: 이 correction은 runner option gate만 복구했다. Harness phase, Implementation Step 0, reference comparison 또는 physics success를 주장하지 않는다.
+
+## 8. Stop Condition
+
+- repeated failure: normalized classification attempt `2`는 초기 Codex `0.147.0` failure history로 보존한다.
+- external mitigation: user/root의 Codex `0.149.1` bounded smoke와 `DECISION-038`이 새 좁은 runner correction을 승인했다.
+- correction result: required adjacent `--disable unified_exec` pair와 regression test가 GREEN이다.
+- residual blocker: runner correction 자체 blocker는 없음. Full Python suite의 pre-existing `xhigh` actual 대 `extra high` expected mismatch는 변경하지 않았다.
+- upstream ambiguity/reference artifact gap: 없음; reference artifact는 읽기/수정/생성하지 않았다.
+- final stop: correction-owned edits와 검증이 끝났으므로 여기서 중단하고, phase rerun 판단과 실행은 Coordinator/Implementation Agent에 반환한다.
+
+## 9. REWORK-004 TDD And Verification Evidence
+
+### Failure and Minimal Correction
+
+- classification: `harness`
+- implementation defect: Codex `0.149.1`에서 통과한 runtime envelope의 `--disable unified_exec` option을 `scripts/execute.py`가 nested `codex exec`에 전달하지 않았다.
+- RED test: `test_invoke_codex_uses_implementation_agent_command_contract`
+- minimal GREEN: command vector에서 `"codex", "exec"` 바로 뒤에 `"--disable", "unified_exec"` 두 argument만 추가했다.
+- preserved behavior: `workspace-write` default/validated override, `--dangerously-bypass-hook-trust`, `gpt-5.6-terra`, `model_reasoning_effort="xhigh"`, 1800-second structured timeout, no-push default, `danger-full-access` 비사용 정책은 변경하지 않았다.

+- attempt: `1`
+- first failed stage command:

+  cmake --build .harness/build --config Debug
+  ```
+
+- failed target or test: Visual Studio 18 generator의 `fesa_solver.vcxproj`와 GoogleTest `gtest.vcxproj` CL task
+- evidence tail: MSBuild `18.8.2`가 `Microsoft.CppCommon.targets(790,5)`에서 `MSB4018`을 냈다. Inner exception은 `System.UnauthorizedAccessException`, HRESULT `0x80070005 (E_ACCESSDENIED)`이며 stack은 `NativeMethods.GetLongFilePath` -> `FileTracker..cctor()` -> `FileTracker.FileIsExcludedFromDependencies` -> `CanonicalTrackedInputFiles.ConstructDependencyTable` -> `CL.ComputeOutOfDateSources`다.
+- command-result caveat: `step1-output.json`의 item 25는 build와 CTest를 세미콜론으로 연결해 aggregate exit `0`을 기록했지만, 그 내부 `cmake --build`는 exit `1`로 실패했다. 뒤따른 stale-build CTest 성공은 Visual Studio build 성공 evidence가 아니다.
+- configure boundary: 보존된 `.harness/build/CMakeCache.txt`는 `CMAKE_GENERATOR=Visual Studio 18 2026`, platform `x64`다. CMake generation 자체가 아니라 생성된 MSBuild project의 CL dependency-tracking 단계가 실패했다.
+
+### 10.3 Root Cause Summary
+
+FESA source, Step 1 test 또는 CMake registration이 원인이 아니다. 서로 독립적인 FESA와 GoogleTest project가 동일한 `FileTracker` static initializer에서 실패하므로 project-local input보다 sandbox/environment boundary다.
+
+Microsoft의 `FileTracker.cs`는 static initialization에서 `Path.GetTempPath()`를 구한 뒤 그 경로에 `GetShortFilePath`와 `GetLongFilePath`를 적용한다. 관찰 stack의 첫 failing native call과 정확히 일치한다. 현재 inherited `TEMP`/`TMP`는 `C:\Users\baram\AppData\Local\Temp`이고 runner는 이를 재지정하지 않는다. 따라서 Codex Windows `workspace-write` restricted token이 workspace 밖 user Temp의 long-path normalization을 거부한 것이 가장 좁은 root-cause inference다.
+
+- boundary confidence: `high` — 두 project에서 같은 FileTracker initializer/`E_ACCESSDENIED`가 재현됨.
+- exact denied-path confidence: `medium-high` — Microsoft source의 static field order와 inherited Temp가 일치하지만 failing API가 path argument를 log하지는 않음.
+- implementation classification: environment-owned sandbox/MSBuild interaction; implementation defect, test defect, CMake registration issue가 아님.
+
+검토한 primary vendor evidence:
+
+- Microsoft MSBuild source: `https://github.com/dotnet/msbuild/blob/main/src/Utilities/TrackedDependencies/FileTracker.cs`
+- Microsoft CL task documentation: `https://learn.microsoft.com/en-us/visualstudio/msbuild/cl-task?view=visualstudio`
+- installed Visual Studio target: `C:\Program Files\Microsoft Visual Studio\18\Community\MSBuild\Microsoft\VC\v180\Microsoft.CppCommon.targets` lines 48-49 and 764-771

+| supported property inspection | installed `Microsoft.CppCommon.targets`; Microsoft CL task docs | `TrackFileAccess` defaults to `true` and is passed to CL; property is vendor-defined for incremental file-access tracking |
+| narrow property smoke | nested `codex exec --sandbox workspace-write ...` requesting exactly `cmake --build .harness/build --config Debug -- /p:TrackFileAccess=false` | 60-second diagnostic timeout before a command completion event; no pass/fail conclusion; exact root PID `13720` and descendants cleaned, then absent |
+| direct sandbox launcher check | `codex sandbox -P :workspace -C C:\git\FESADev\.worktrees\nonlinear-static-newton-raphson cmd.exe /d /c echo SANDBOX_OK` | 10-second timeout; no `SANDBOX_OK`; exact root PID `16708` tree cleaned, then absent |
+| workspace-write alternative evidence | Visual Studio-bundled Ninja/MSVC build in `step1-output.json` | focused CTest 27/27 and full CTest 228/228 passed |
+
+`/p:TrackFileAccess=false`는 vendor-defined 후보지만 동일 `workspace-write`에서 build completion이 관찰되지 않아 safe workaround로 채택할 수 없다. `TEMP`/`TMP`를 worktree로 재지정하는 후보도 FileTracker가 system-wide Temp를 dependency exclusion 기준으로 사용한다는 Microsoft source comment 때문에 tracking semantics 보존을 입증하지 않고 자동 적용하지 않았다.
+
+Ninja/MSVC는 같은 sandbox에서 implementation/test 건전성을 입증하지만 Step 1 VERIFY가 명시한 `Visual Studio 18 2026` generator acceptance criterion을 대체하지 않는다. 따라서 correction-agent가 phase/upstream contract 변경 없이 자동 채택할 수 없다. `danger-full-access`는 지시대로 실행하거나 시험하지 않았다.
+
+### 10.6 Traceability

+
+### 10.7 Handoff Recommendation
+
+- recommendation: `needs-user-decision`; Coordinator Agent에 `blocked` 반환.
+- safe automatic correction: 없음. Runner/CMake/Step 1 source를 변경하지 않는다.
+- decision option 1: approved implementation plan/phase owner가 Ninja+MSVC를 Visual Studio generator 대체 evidence로 명시적으로 승인한다. 이는 correction-agent 범위 밖의 upstream acceptance 변경이다.
+- decision option 2: 사용자가 `docs/HARNESS.md`의 isolated clean-worktree `danger-full-access` fallback을 명시적으로 승인한다. 이번 진단에서는 broader privilege를 사용하거나 시험하지 않았다.
+- decision option 3: Codex/Windows sandbox 환경 소유자가 direct `:workspace` launcher와 user Temp long-path access 문제를 수정한 뒤 동일 Visual Studio build를 재검증한다.
+
+### 10.8 Stop Condition
+
+- repeated failure: normalized classification attempt `1`; 같은 classification의 두 번째 자동 rework는 아직 수행하지 않았다.
+- environment blocker: direct `:workspace` no-op도 bounded completion을 내지 않아 workspace-only workaround를 신뢰성 있게 검증할 수 없다.
+- upstream ambiguity: Ninja acceptance 또는 broader sandbox 권한은 사용자/Coordinator 결정이 필요하다.
+- reference artifact gap: 없음; reference artifact는 읽기/수정/생성하지 않았다.
+- final stop: safe, vendor-supported, contract-preserving `workspace-write` workaround가 입증되지 않아 code change 없이 `blocked`로 중단한다.

+
+### 11.3 Root Cause Summary
+
+FESA C++/test/CMake target defect가 아니라 Visual Studio generator의 MSBuild FileTracker와 `workspace-write` sandbox 사이 environment failure였다. User가 option A를 승인했으므로 tracked root `CMakePresets.json`과 existing Harness preset adapter를 사용해 동일 MSVC x64 Debug compiler를 Ninja로 구동한다. Harness Python은 이미 complete preset triplet과 parent environment copy를 지원하므로 production Python 변경은 필요하지 않았다.

+- correction-agent reproduction: the exact focused test alone failed deterministically in 103.84 seconds with the same diagnostic. The original reference input was not passed to FESA.
+
+### 12.3 Root Cause Summary
+
+This is not an implementation defect in the observed convergence calculation. The implementation in `src/fesa/analysis/nonlinear_static_procedure.cpp` supplies same-trial free rotational residual, internal moment and external moment to `EvaluateNewtonConvergence`. `src/fesa/analysis/nonlinear_static_control.cpp` then implements the approved `NSNR-069` and formulation Section 14.1 literally:
+
+\[
+D_M=\max(\|f_{int,f}^{\phi}\|_\infty,
+          \|f_{ext,f}^{\phi}\|_\infty),\qquad
+\eta_M=\frac{\|r_f^{\phi}\|_\infty}{D_M}
+\]
+
+for every nonzero \(D_M\), with the typed absolute `1e-3 force-length` branch available only when \(D_M=0\) exactly.
+
+The approved `reference/shellNL/shellNL.inp` contains only `Set-1, 3, -100000.` under `*CLOAD`; it applies no rotational moment component. Therefore the free rotational external vector is exactly zero and
+
+\[
+r_f^{\phi}=f_{int,f}^{\phi}-0=f_{int,f}^{\phi},
+\qquad
+D_M=\|f_{int,f}^{\phi}\|_\infty=\|r_f^{\phi}\|_\infty.
+\]
+
+For every nonzero rotational residual, \(\eta_M=1>10^{-2}\). The channel can pass only if floating-point assembly produces the exact zero vector, at which point and only then the exact-zero branch is selected. Thus the current approved denominator structurally prevents practical convergence for a no-applied-moment shell case even when its residual is well below the approved typed absolute threshold.
+
+The reproduced log contains 100/100 parsed iteration records with exact printed equality between `residual_moment_numerator_norm` and `residual_moment_denominator_scale`; all 100 use `branch=relative` and `pass=0`. Representative values are:
+
+| iteration | numerator | denominator | branch | pass |
+| ---: | ---: | ---: | --- | ---: |
+| 1 | `2.363968570753043e-09` | `2.363968570753043e-09` | `relative` | 0 |
+| 2 | `1.4372536725204554e-06` | `1.4372536725204554e-06` | `relative` | 0 |
+| 3 | `3.138301877925187e-06` | `3.138301877925187e-06` | `relative` | 0 |
+| 99 | `3.8876064110127118e-06` | `3.8876064110127118e-06` | `relative` | 0 |
+| 100 | `4.6441010823627948e-06` | `4.6441010823627948e-06` | `relative` | 0 |
+
+Every listed numerator is below `1e-3 force-length`, but the approved exact-zero-denominator predicate forbids use of that absolute branch. Changing the implementation alone would contradict the approved requirement and formulation.

+
+### 12.7 Handoff Recommendation
+
+- recommendation: return `upstream-contract` / `needs-user-decision` to Coordinator Agent. Do not request an Implementation Agent rerun yet.
+- narrowest contract alternative: when the matching external residual-channel scale is exactly zero, select the existing typed absolute gate (`||r_f^phi||inf <= 1e-3 force-length`) even if the internal residual is nonzero; retain the current relative denominator when matching external scale is nonzero.
+- broader contract alternative: make residual convergence pass when either its typed absolute gate or its current relative gate passes. This is simpler and symmetric across force/moment channels but changes acceptance for all load-scale regimes.
+- scale-based contract alternative: define an explicit nonzero model force-length reference scale for moment residual normalization, including its deterministic characteristic-length source. This is more general but expands the numerical contract and needs formulation/numerical review.
+- non-solution: changing the reference deck to add an applied moment would not correct the same structural failure for supported no-moment load cases and would also violate immutable reference ownership in this correction.
+
+Any selected alternative requires the owning upstream documents and tests to be revised and approved before production code changes. Correction Agent does not choose among them.
+
+### 12.8 Stop Condition
+
+- upstream ambiguity: the exact approved `max(internal, external)` denominator and exact-zero branch are the demonstrated cause.
+- implementation stop: any code-only pass would relax/reinterpret `NSNR-069` and formulation Section 14.1.
+- reference artifact gap: none; all declared reference artifacts exist and remain unchanged.
+- repeated failure: normalized classification attempt `1`; no automatic second implementation correction is safe before an upstream decision.
+- final stop: status `needs-upstream-decision`; Step 11 remains blocked and Step 12 remains pending.

+
+### 13.3 Root Cause Summary
+
+Observed reaction computation/storage/mapping path에는 implementation defect evidence가 없다.
+
+1. `nonlinear_static_procedure.cpp`는 같은 accepted state에서 `residual = internal.force - external.generalized_external_force`를 만들고 `trial.reaction = trial.residual`로 저장한다. `nonlinear_analysis_state.cpp`는 모든 DOF에서 이 두 identity를 검증한다.
+2. `nonlinear_hdf5_results_writer.cpp`는 translation reaction을 그대로 쓰고 rotational reaction만 승인식 `J_l(phi)^(-T)`로 physical spatial moment에 변환한다. 24 constrained nodes에서 `phi=0`이므로 이 변환은 identity다. Full-precision HDF5 audit에서 constrained translation과 generalized residual의 차이, constrained moment 변환 차이, constrained `phi`가 모두 exact `0`이었다.
+3. Comparator는 `/model/nodal_constraint_mask`와 `(case, state, instance, node label, component)` exact key를 사용한다. 이번 실행이 schema/missing/extra/duplicate/nonfinite failure가 아니라 family tolerance report까지 도달했으므로 storage와 row mapping precheck도 통과했다.
+4. Dominant RF3/RM1/RM2 mismatch는 nonlinear 전용 경로에서 생기지 않는다. FESA nonlinear-linear 최대 차이는 RF3 `2.9441580409184098e-06`, RM1 `1.3046948879491538e-05`, RM2 `1.2039316061418504e-05`이고, Abaqus nonlinear-linear 차이는 각각 `0`, `5.0022208599999994e-12`, `1.1141310098e-11`이다. 그럼에도 FESA linear와 Abaqus linear 사이에는 nonlinear과 동일한 local RF3/RM mismatch가 이미 존재한다. 예를 들어 node 31 RF3는 FESA `1059.5675655371299`, reference `339.61334199999999`; node 22 RM1은 FESA `-1564.1175318019484`, reference `-515.62542699999995`다.
+5. 전체 constrained reaction 합은 FESA nonlinear `[7.9591888635377472e-12, 7.2906680692597092e-12, 100000.00000082512]`, Abaqus nonlinear `[4.5008441418303846e-13, -1.7997131562808022e-12, 99999.999592799955]`로 global balance와 sign이 일치한다. Stored `/global/equilibrium`도 `[-5.2007287365540833e-12, 2.1302730413008675e-11, 99999.999999999985, 1.5669833723712425e-11, 6.4043503405991029e-12, -3.0183203934097235e-11]`다.
+6. RF1/RF2는 nonlinear에서 새로 생기는 weak geometric membrane reaction이지만 FESA extrema `±1.3774894254907935`와 Abaqus extrema `±1.9166318200000001`의 차이는 storage/mapping 오류가 아니다. Linear Abaqus reaction은 거의 zero이고, independent FESA MITC4와 Abaqus S4가 서로 다른 local nodal support-force redistribution을 만들 수 있다는 approved formulation/model limitation 안에 있다.
+
+따라서 demonstrated cause는 nonlinear reaction implementation이 아니라 reference blocking quantity의 model-adequacy 전제다. Approved `reference-model.md`는 linear reaction CSV를 review-only로 두면서, 같은 local RF3/RM distribution을 nonlinear에서 blocking으로 승격한다. Project contract는 FESA MITC4의 integration/stabilization/internal behavior가 Abaqus S4와 동등하다고 주장하지 않는다. Global equilibrium은 맞지만 formulation-sensitive local nodal reaction 분포가 1% RMS를 만족해야 한다는 분석적 또는 독립 benchmark 근거는 없다. 이를 code-only로 Abaqus 값에 맞추는 것은 formulation/model adequacy 또는 reference acceptance contract 변경이며 Correction Agent 범위를 벗어난다.
+
+### 13.4 Correction Scope
+
+- changed report file in this rework: `docs/nonlinear-static-newton-raphson/corrections.md`
+- changed production source/header/test/CMake files in this rework: none
+- preserved pre-existing dirty Step 11 files, including selector/control/log tests, comparator/reference tests, plan/phase/coordination and upstream approval edits
+- excluded upstream contract files: `requirements.md`, `formulation.md`, `numerical-review.md`, `reference-model.md`, `io.md`, `docs/TOLERANCE.md`
+- excluded immutable/reference files: `reference/**`, stored Abaqus CSV, HDF5 schema and tolerance policy
+- prohibited actions not performed: new RED test without an implementation defect, production/comparator/test/CMake change, tolerance weakening, reference artifact generation/modification, Abaqus/Nastran/reference solver, Harness phase execution, Step 12/Physics/Release advancement, `danger-full-access`, commit, push
+
+No focused RED test was added because the dataflow audit disproved a bounded nonlinear computation/storage/mapping defect. The existing focused integration test is already RED for an upstream blocking/model-adequacy assumption; encoding a replacement expected result before upstream approval would itself change that contract.
+

+
+### 13.7 Handoff Recommendation
+
+- recommendation: return `upstream-contract` / `needs-user-decision` to Coordinator Agent. Do not request an Implementation Agent rerun and do not advance Step 12 until an upstream alternative is explicitly selected and approved.
+- recommended narrow alternative: align nonlinear local nodal RF/RM disposition with the approved linear reference contract—keep local rows as read-only model-adequacy/physics-review evidence, while blocking reaction evidence is global force/moment equilibrium plus free-residual checks. Blocking displacement comparison remains unchanged.
+- local-to-global alternative: retain reaction as a blocking external quantity only after projecting it to formulation-independent global resultant force/moment families; keep exact local nodal rows as warning/characterization evidence.
+- local-blocking alternative: if exact local RF/RM rows must remain blocking, Numerical Review/Reference Model owners must supply an analytical or independent formulation-appropriate benchmark, or explicitly approve Abaqus S4 local nodal reaction distribution as an FESA MITC4 model-adequacy target after a mesh/formulation study. Implementation must not calibrate reactions to Abaqus without that decision.
+- excluded alternative: tolerance relaxation, row averaging/collapse, comparator weakening or reference artifact rewriting is not acceptable.
+
+Each viable alternative changes blocking quantity/model-adequacy ownership in `requirements.md`, `numerical-review.md`, `reference-model.md`, `io.md` and the implementation/reference plan. Correction Agent does not select or edit those contracts.
+
+### 13.8 Stop Condition
+
+- upstream ambiguity: current contracts simultaneously disclaim Abaqus S4 internal equivalence, make linear local reaction review-only, and require the same formulation-sensitive local distribution as nonlinear blocking evidence.
+- implementation stop: no nonlinear reaction computation, storage or exact-key mapping defect was reproduced; a code-only pass would alter formulation/reference meaning.
+- reference artifact gap: none; required artifacts exist, remained read-only and have empty reference diff.
+- environment blocker: none; configure/build/discovery completed and full CTest reproduced only the intended reference failure.
+- repeated failure: `REWORK-008` classification attempt `1`; no automatic implementation correction is safe before the upstream decision.
+- final stop: status `needs-upstream-decision`; Step 11 remains blocked, Step 12 remains pending, and Physics/Release remain ineligible.

+
+### 14.3 Root Cause Summary
+
+이번 실패는 solver, comparator 또는 `1e-8` gate defect가 아니라 Harness child launch environment defect다.
+
+1. 이전 launcher filter는 `C:\Program Files\WindowsApps\Microsoft.PowerShell_*` entry만 제거했다.
+2. 따라서 `C:\Users\baram\AppData\Local\Microsoft\WindowsApps` entry와 그 아래 `pwsh.exe` execution alias가 PATH에 남았다.
+3. Nested Codex shell resolver는 남은 user-local alias를 선택했고, Windows native `workspace-write` sandbox는 그 alias의 child process 생성을 Windows error 5로 거부했다.
+4. PATH에서 `\\WindowsApps(?:\\|$)`에 일치하는 모든 entry를 제거하면 현재 환경의 Program Files entry 세 개와 user-local entry 한 개가 함께 제거된다. 이때 `pwsh`는 resolve되지 않고 `powershell`은 `C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe`로 resolve된다.
+5. Root가 같은 Codex CLI `0.150.1`, `gpt-5.6-terra`, `xhigh`, `--disable unified_exec`, `workspace-write`, `CODEX_HOME=C:\Users\baram\.codex` envelope에서 이 filter를 적용한 nested smoke는 위 Windows PowerShell을 선택해 exact `FESA_CODEX_SHELL_SMOKE_OK`를 출력하고 exit `0`으로 끝났다. Correction audit의 독립 direct smoke도 같은 executable, exact output과 exit `0`을 확인했다.
+
+따라서 repository runner나 Step 11 implementation을 고칠 필요가 없다. Rerun launch에서 PATH predicate만 전체 WindowsApps entry를 제거하도록 바로잡으면 된다.

+
+### 14.7 Handoff Recommendation
+
+- recommendation: return `corrected-for-implementation-rerun` to Coordinator Agent and request one bounded Implementation Agent rerun of Step 11 only.
+- exact launch correction: reuse the approved `STEP11-EXECUTION-003` Step11-only wrapper and change only the launch PATH filter to the following predicate after VsDevCmd x64/dependency environment setup and before `codex exec`:
+
+  ```powershell
+  $step11PathEntries = $env:PATH -split ';' | Where-Object {
+      $_ -and $_ -notmatch '\\WindowsApps(?:\\|$)'
+  }
+  $env:PATH = $step11PathEntries -join ';'
+  $env:CODEX_HOME = 'C:\Users\baram\.codex'
+  $env:FESA_HARNESS_CODEX_SANDBOX = 'workspace-write'
+  ```
+
+- preserve exact runtime: Codex CLI `0.150.1`; implementation-agent `gpt-5.6-terra`/`xhigh`; `--disable unified_exec`; project PreToolUse/Stop hooks; VsDevCmd x64; approved `FESA_GTEST_SOURCE_DIR`, `MKL_DIR`, `TBB_DIR`, `HDF5_DIR`.
+- preflight must resolve `powershell` to `C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe`, leave `pwsh` unresolved, and print exact `FESA_CODEX_SHELL_SMOKE_OK` with exit `0`.
+- run only Executor-selected Step 11, no `--push`; hard-stop before Step 12. Do not use `danger-full-access`, run a reference solver, mutate reference artifacts or alter runner/source/test/CMake/phase/upstream/tolerance files as part of this launch correction.
+
+### 14.8 Stop Condition
+
+- repeated failure: normalized classification count is already `2`; if the corrected all-WindowsApps filter still produces the same `CreateProcessAsUserW` failure, do not start another automatic retry. Return `needs-environment-fix` to Coordinator with the new output artifact.
+- environment blocker: cleared for one bounded Step 11 rerun by the same-envelope smoke; no repository-local code fix is required.
+- upstream ambiguity: none introduced by this correction; fixed `1e-8` force/moment gate and all approved contracts remain unchanged.
+- reference artifact gap: none examined or changed in this correction.
+- final stop: status `corrected-for-implementation-rerun`; Step 11 and Step 12 remain `pending` until Executor/Implementation owner action.

 ## Readiness Check
 
-- Upstream document status: Stage 1 requirements approved, Stage 2 research passed, Stage 3 formulation ready for numerical review and approved downstream, Stage 4 numerical/reference review passed for I/O definition, Stage 5 I/O definition approved.
+- Upstream document status: Stage 1 requirements, Stage 4 numerical/reference review and Stage 5 I/O definition are complete; REAPPROVAL-012 fixes both factor-one normalized global force and moment balance gates at `<=1e-8`. Stage 3 formulation §§11.4/13.4 already supplies the accepted residual/reaction/global-resultant meaning.
 - Missing decisions: none.
-- Missing required comparison files: none for declared blocking/reference families.
+- Missing required comparison files: none. Fine primary, coarse companion and linear-control exact inputs/CSVs are present; stress files are optional inventory only.
 - Planning can proceed: yes.
-- `.harness/config.json`: absent during planning inspection. Each Step must recheck at execution time and use it first if it appears.
+- REWORK-008의 local reaction blocking conflict는 USER-DECISION-004 option 1로 해소되었다. Local nodal RF/RM은 review-only이고 factor-one global force/moment balance와 accepted free residual이 blocking이다. `AUDIT-001` current-arm/spatial-moment implementation seam은 Step 11에서 RED-first로 닫는다.

+  `NSNR-HDF5-014`, `NSNR-REF-001..023`, residual-selector GREEN과 comparator/CMake 작업이 있다.
+  새 계획은 이를 reset/replay하지 않는다.
+- `implementation-report.md`, `build-test.md`, canonical `reference-comparison.md`는 아직 없고 Step 12가 actual evidence에서만 생성한다.
+- `CMakePresets.json` tracks the approved `windows-msvc-ninja-debug` contract. The ignored `.harness/config.json` selects the matching configure/build/test presets and `.harness/build-ninja-msvc-debug` binary directory.

+## Implementation Scope
+
+Included behavior:
+
+- Existing schema-v1 `/global/equilibrium [6]`에 global origin `[0,0,0]`, accepted current
+  position `X+u`, independently spatial-converted applied/reaction moments를 사용하는
+  applied-plus-reaction balance error를 기록한다.
+- Existing schema-v1 nodal datasets와 exact constraint mask에서 accepted free residual,
+  constrained reaction resultant와 global balance error를 서로 다른 evidence로 재구성한다.
+- Fine nonlinear primary, coarse nonlinear companion와 linear control을 exact read-only artifact로
+  비교한다. U는 blocking, UR은 warning-only, local RF/RM은 review-only, RM3/stress는 excluded다.
+- Internal global force/moment는 dimension-separated normalized `1e-8`, accepted free residual은
+  NSNR-069으로 blocking 검증하고 external families만 `docs/TOLERANCE.md`를 사용한다.
+
+Excluded behavior and non-goals:
+
+- New HDF5 dataset/schema version, public header/API, tolerance, reference artifact 또는 solver scope
+  추가가 아니다.
+- `fesa.env`, runtime configuration, CLI option 또는 product solver acceptance behavior를 추가하지
+  않는다. `1e-8`은 comparator-owned internal verification gate의 fixed value다.
+- Local nodal reaction을 global sum으로 대체하거나 Abaqus S4와 FESA MITC4 내부 정식화
+  동등성을 주장하지 않는다.
+- Steps 0–10 구현/history replay, selector RED 재현, Abaqus/reference solver 실행, Physics/Release
+  판정은 포함하지 않는다.

 ## Validation Commands
 
 Each Step must:
 
-1. Recheck `.harness/config.json`. If present, use the configured Harness build/test commands.
-2. If absent, use:
+1. Use the ignored `.harness/config.json` preset contract and tracked `CMakePresets.json`.
+2. Confirm the Harness parent environment was initialized by VsDevCmd x64 and contains `FESA_GTEST_SOURCE_DIR`, `MKL_DIR`, `TBB_DIR`, and `HDF5_DIR`.
+3. Run:
 
 ```powershell
-cmake --fresh -S . -B .harness/build -G "Visual Studio 18 2026" -A x64 `
-  "-DFESA_GTEST_SOURCE_DIR=$gtestSource" `
-  "-DMKL_DIR=$mklDir" `

+ctest --preset windows-msvc-ninja-debug --show-only=json-v1
+ctest --preset windows-msvc-ninja-debug --output-on-failure
 ```
 
-Focused CTest commands are written explicitly in each `stepN.md`.
+Step 11 focused commands additionally include:
+
+```powershell

 Harness Python validation is not in scope unless a Step changes Harness Python behavior, hook behavior, or agent configuration.
 
 ## Risks And Downstream Handoff
 
-- Main implementation risk: current `LinearStaticAnalysis` owns parse/map and HDF5 write internally. Step 10 must refactor through prepared analysis flow so log close precedes HDF5 finalization for both linear and nonlinear runs.
-- Main numerical risk: nonlinear MITC4 tangent and finite rotation derivatives must pass internal derivative/objectivity tests before reference comparison can be meaningful.
-- Main backend risk: nonlinear tangent can be nonsymmetric. Preserve SPD `MklPardisoSolver` unchanged and add separate `TangentSolver`.
-- Handoff to Implementation Agent through Coordinator: execute Steps 0..12 in order, one current Step at a time, with RED observed failure evidence before GREEN implementation, then focused/full CTest. Final reference gate is Step 11; evidence-document closure is Step 12.
+- Current numerical risk: nonzero prescribed motion exposes the existing raw-residual/initial-arm
+  shortcut. The minimal fix must preserve same-state, stable-order and mask-before-spatial-conversion
+  semantics; passing zero-prescribed shellNL cases alone is insufficient evidence.
+- Current reference risk: fine/coarse U and internal balance/free-residual are blocking, but local RF/RM
+  may still show large review-only errors. Do not convert those findings into omitted rows, relaxed
+  tolerance or a blocking gate.
+- Current worktree risk: Step 11 contains partial selector/comparator/CMake edits. Preserve and continue
+  those files; do not delete, reset, replay selector RED or replace the comparator design wholesale.
+- Handoff to Implementation Agent through Coordinator: after a separate explicit Harness request,
+  resume only Executor-selected Step 11. Preserve existing `NSNR-PROC-019`, `NSNR-HDF5-014` and
+  `NSNR-REF-020..023`; first re-observe the current-case old-gate RED, then add `NSNR-REF-024..025`
+  before changing the comparator-only shared force/moment gate to `1e-8`. Verify preserved
+  selector/log tests, then run focused/full preset validation.
+  Step 12 remains actual-evidence closure.

+## Harness Step Draft
+
+| Step | name | one-module scope | prerequisites | stop condition |
+| ---: | --- | --- | --- | --- |
+| 11 | `equilibrium-projection-and-reference-gate` | Nonlinear accepted equilibrium projection, exact HDF5 location and test-private reference gate | Steps 0–10 completed; approved upstream hashes; partial Step 11 work preserved; VsDevCmd/preset dependency environment | Stop on unexpected RED, public API/schema/tolerance/reference change, reference mutation, or any focused/full failure. |
+| 12 | `execution-closure-and-evidence-docs` | Fresh evidence reports plus directly superseded PRD/ARCH/ADR statements | Step 11 completed with actual command/reference evidence | Stop if Step 11 is incomplete, evidence is stale/untraceable, a code/test/CMake change is needed, or any final command fails. |
+
+Both Step files contain exact commands, file ownership, RED/GREEN/VERIFY order and prohibitions.
+Materialization does not select or execute either Step.
 
 ## Open Issues
 
-None.
+None blocking planning. Revised upstream contracts and exact required artifacts are complete; actual
+RED/GREEN/build/reference outcomes remain Step 11/12 evidence and are not pre-claimed.
 
 ## Plan Approval Boundary
 
-The user-approved plan and pending phase files do not authorize Harness execution. `scripts/execute.py nonlinear-static-newton-raphson` requires a separate explicit user request.
+The Coordinator-audited REAPPROVAL-012 revision authorizes this planning/phase materialization and
+blocked-to-pending recovery. It does not itself execute Harness; Executor invocation remains under
+the Coordinator's separately audited execution authority.

+
+Before any build or reference command, `NSNR-EVID-001..007` failed as expected.
+`implementation-report.md`, `build-test.md`, and `reference-comparison.md` were absent. The
+global documents still advertised `--output`, only the prior linear output path, and did not state
+the approved nonlinear current-arm/reaction and fine/coarse reference dispositions. This was an
+evidence freshness failure, not a solver failure. No report was created until the fresh commands
+below completed.

+Its RED evidence covered: initial-arm/raw rotation balance (`NSNR-PROC-019`), obsolete
+`location=global-origin` (`NSNR-HDF5-014`), missing fine inventory (`NSNR-REF-020`), blocking
+local RF/RM (`NSNR-REF-021`), obsolete `1e-10` balance rejection (`NSNR-REF-022`), pre-tolerance
+row rejection (`NSNR-REF-023`), inclusive `1e-8` boundary (`NSNR-REF-024`), and exact-zero scale
+(`NSNR-REF-025`).
+
+The minimal GREEN slice was limited to the nonlinear procedure current-arm/spatial balance
+projection, HDF5 location metadata/self-check, and test-private reference comparator/case
+inventory. The relevant production files were `nonlinear_static_procedure.cpp`,
+`nonlinear_hdf5_results_writer.cpp`, and `hdf5_self_check.cpp`; test changes remained in the
+procedure, writer, convergence/log, and reference-comparator tests. This Step made no C++, test,
+CMake, Harness, tolerance, or reference-artifact change.
+
+Fresh VERIFY reran the preserved controls. The focused `NonlinearStaticProcedure` and
+`NonlinearHdf5ResultsWriter` command passed 7/7, including
+`NonzeroPrescribedMotionWritesCurrentArmSpatialAppliedPlusReactionBalance` and
+`WritesSchemaV1GlobalBalanceErrorLocation`. The reference command passed the inclusive and
+exact-zero global gate tests. This closes `AUDIT-001`: the tests exercise nonzero prescribed
+translation and rotation, `x=X+u`, component-mask-before-conversion, independently converted
+applied and constrained rotation covectors, and `location=global-balance-error`.

+
+Implementation-owned classification is `pass-for-physics-evaluation`. The only numerical
+differences retained are six deterministic local RF/RM review-only findings; they do not alter
+the blocking verdict. No warning-only UR family failed. This report does not claim physics or
+release readiness, and numerical agreement does not assert Abaqus S4 internal formulation
+equivalence.
+
+No Step 12 production behavior changed. Reference inputs and CSV files were read-only and their
+pre/post inventory, byte sizes, timestamps, and SHA-256 values were identical.

+global origin `[0,0,0]`, current force arm과 spatial physical nodal moment를 지정했으므로 이
+dataset의 authoritative meaning은 처음부터 formulation §13.4의 **global
+applied-plus-reaction balance error**다. Raw full-residual sum, initial-coordinate arm 또는 raw
+rotation-coordinate covector를 이 path에 쓰는 것은 schema-compatible implementation이 아니다.
+이 의미 명확화는 path, shape 또는 component를 바꾸지 않으므로 schema version을 올리지 않는다.
+
+같은 accepted frame의 세 equilibrium quantity는 다음처럼 서로 다른 HDF5 projection으로
+재구성된다. 별도 중복 summary dataset은 만들지 않는다.

+| constrained reaction resultant | `/model/nodal_constraint_mask`를 `/nodal/generalized_residual`에 먼저 적용해 constrained generalized reaction을 만들고, rotation block만 accepted `phi`의 `J_l(phi)^(-T)`로 spatial moment로 변환한다. Current position은 `/model/nodes.coordinates + /nodal/displacement[UX,UY,UZ]`다.

Stable node order로 formulation §13.4의 합을 계산한다. | global force `[3]`, global spatial force-length moment `[3]` about `[0,0,0]` | `blocking-internal` |
+
+Componentwise constraint selection은 spatial moment 변환보다 먼저 수행한다. 따라서 partial
+rotational constraint나 nonzero prescribed rotation에서도 constrained reaction resultant에 free
+generalized residual이 섞이지 않는다. Local `/nodal/reaction` display나 full residual sum을 위 세
+quantity 중 다른 하나의 substitute로 사용하지 않는다. Nonzero prescribed translation에서는

+
+Internal equilibrium은 Abaqus CSV comparison이 아니다. Fine primary와 coarse companion의
+각 accepted factor-one HDF5 frame에서 Section 7.5.1의 projection을 사용한다.
+
+| family id | exact HDF5 rows/components | gate |
+| --- | --- | --- |
+| `coarse.accepted_free_force_residual` | 75 free `RU1/RU2/RU3` rows와 같은 rows의 internal/external force | NSNR-069 force channel |
+| `coarse.accepted_free_moment_residual` | 75 free `RPHI1/RPHI2/RPHI3` rows와 같은 rows의 internal/external generalized moment | NSNR-069 moment channel |
+| `coarse.global_force_balance` | factor-one `/global/equilibrium` `FORCE_1..3` | normalized `<=1e-8` |
+| `coarse.global_moment_balance` | factor-one `/global/equilibrium` `MOMENT_1..3` | normalized `<=1e-8` |
+| `fine.accepted_free_force_residual` | 1,875 free `RU1/RU2/RU3` rows와 같은 rows의 internal/external force | NSNR-069 force channel |

+| `fine.global_moment_balance` | factor-one `/global/equilibrium` `MOMENT_1..3` | normalized `<=1e-8` |
+
+Global balance의 force scale은 applied/reaction nodal force contribution의 2-norm 합 중 큰
+값, moment scale은 current-arm force moment와 spatial physical nodal moment contribution의
+2-norm 합 중 큰 값이다. Force와 moment를 분리해 `norm(balance_error)/scale<=1e-8`을
+적용한다. Scale이 exact zero이면 balance error도 exact zero일 때만 pass한다. Absolute floor,
+`max(1,S)` 또는 zero clamp는 없다. Accepted free residual은 NSNR-069의 external-channel exact-zero/
+nonzero branch를 그대로 재현한다. 이 internal gate에는 `docs/TOLERANCE.md`, Abaqus value 또는
+local reaction error를 적용하지 않는다.
+
+Constrained reaction resultant force `[3]`와 moment `[3]`는 Section 7.5.1의 distinct
+`review-only-summary`로 함께 계산·보고한다. `/global/equilibrium`, constrained reaction
+resultant와 accepted free residual 중 어느 하나를 다른 quantity의 대체 dataset으로 쓰지 않는다.

-  의미 또는 reference identity와 충돌하는 blocking defect는 확인되지 않았다.
-- reference readiness: `reference/shellNL` 및 `reference/shell`의 선언 파일과 CSV는
-  읽을 수 있고 row identity/precheck/tolerance 계약을 정의할 수 있다.
-- boundary: 이 verdict는 I/O Definition 진입 허가이며 implementation, reference comparison
-  pass, physics evaluation 또는 release readiness 승인이 아니다.
-
-`reference/shellNL`은 `nlgeom=YES`와 factor-one final frame을 갖는 저장 reference로 사용할 수
-있지만, 주요 `U3`와 stress 값은 선형 `reference/shell`과 거의 같다. 관찰된 nonlinear 신호는
-주로 약한 in-plane coupling이다(`RF1/RF2` 최대 약 `1.9166`, `U1/U2` 최대 약
-`1.29e-11`). 따라서 이 CSV 세트만으로 finite-rotation objectivity, exact tangent,
-rollback 또는 큰 변위 benchmark를 통과했다고 판단하지 않는다. 해당 항목은 아래의
-blocking internal tests로 분리한다.
+- reason: 승인 정식화는 fixed-initial-reference Total Lagrangian MITC4, finite rotation,
+  nonlinear `24 -> 20` map, objective drilling, same-trial residual/tangent, reaction의
+  spatial-moment 변환과 current-arm global balance를 구현 가능한 수치 계약으로 정의한다.
+  Revised requirements와 충돌하는 formulation defect는 없다.
+- reaction disposition: local nodal `RF1/RF2/RF3`와 physical spatial `RM1/RM2`는 exact
+  source-key/schema/inventory/finite/error evidence를 유지하는 `review-only`다. 이 값은
+  formulation-sensitive nodal redistribution이므로 blocking verdict를 결정하지 않는다.
+  Local `RM3`는 계속 제외한다.
+- blocking equilibrium: 각 nonlinear case의 factor-one accepted state에서 `(a)` global
+  applied-plus-reaction force balance, `(b)` global applied-plus-reaction moment balance,
+  `(c)` accepted free-DOF force/moment residual evidence가 blocking이다. `(d)` constrained
+  reaction resultant는 별도 quantity로 보존하지만 balance error를 대신하지 않는다.
+- reference readiness: `reference/shell`, `reference/shellNL`와
+  `reference/shellNL-meshfine`의 선언 input 및 필요한 displacement/reaction CSV가 존재하고
+  읽을 수 있다. Fine case는 사용자가 요청한 mesh-refined nonlinear evidence이며 coarse
+  case와 서로의 reference에 독립적으로 비교한다. Merge 후 추가된 read-only
+  `reference/shellNL-meshfine_02` bundle도 별도 verification 대상으로 inventory했다. 이
+  post-closure 추가는 기존 세 case의 gate, 과거 Stage 6 comparison 또는 Release verdict를
+  소급 변경하지 않는다.
+- boundary: `pass-for-io-definition`은 I/O 계약을 다시 정의할 수 있다는 뜻이며 reference
+  comparison pass, implementation completion, physics 또는 release 승인이 아니다.

+1. **Global applied-plus-reaction balance error**: applied와 constrained reaction을 더한
+   force `[3]`와 moment `[3]`; blocking.
+2. **Constrained reaction resultant**: constrained reaction만 합한 force `[3]`와 current-arm

-MMS, broader locking/distortion characterization은 유용하지만 승인된 Stage 4 pass 조건은 아니다.
+현재 nonlinear implementation helper는 full residual을 합하고 initial Domain coordinates와
+raw rotational generalized residual을 사용한다. 현재 `shellNL`/`shellNL-meshfine` support는
+prescribed `u=phi=0`이므로 initial/current support arm과 generalized/spatial support moment가
+일치하고, 이 helper는 작은 free residual을 제외하면 constrained reaction resultant에
+가깝다. 그러나 applied load를 더한 balance error는 아니며 세 quantity 중 어느 것도
+일반적으로 대체하지 못한다. 지원 범위의 nonzero prescribed translation/rotation에서는
+반드시 current position과 `J_l(phi)^(-T)` spatial-moment conversion을 적용해야 한다.
+
+### 3.3 Numerical risks and nonblocking artifact issue
+
+- Fine stress CSV에는 element `1`, `SNEG`의 `Node Label=ss` 한 행이 있다. Stress는 승인된
+  FESA Gauss direct recovery와 위치가 다르고 수치 comparison에서 제외되므로 이 optional
+  inspection artifact의 malformed identity는 I/O 진입 blocker가 아니다. Artifact를 repair,
+  normalize 또는 rewrite하지 않는다.
+- Coarse/fine Abaqus `S4`와 FESA MITC4가 동일한 local support reaction distribution을
+  만들어야 한다는 formulation evidence는 없다. Global balance와 free residual로 blocking
+  physics를 검증하고 local rows는 오차를 숨기지 않은 채 review-only로 남긴다.
+- Stored cases의 response는 weak geometric-nonlinear regime다. Reference displacement pass가
+  tangent, objectivity, finite-rotation 또는 rollback 검증을 대신하지 않는다.
+- `shellNL-meshfine_02`는 topology와 constraint inventory는 fine case와 같지만 source load가
+  `F1=+1e8`, `F2=+1e8`, `F3=-1e8`이다. 기존 fine case의 `F3=-1e5`와 같은 물리 case 또는
+  mesh-only refinement로 취급하지 않으며 각자의 reference에만 비교한다.
+
+### 3.4 Open questions

+I/O Definition 진입을 막는 open question은 없다. Public large-response benchmark, shell MMS와
+broader locking/distortion portfolio는 useful future evidence지만 이번 gate의 추가 조건이 아니다.
 
 ## 4. Numerical Risk Assessment
 
 | risk label | assessment | required control / downstream evidence |
 | --- | --- | --- |
-| `rigid_body_modes` | 물리/internal/drill energy가 finite rigid motion에서 objective해야 하며 pure drill만 regularized 되어야 한다. | finite rigid translation/rotation superposition에서 strain, stress, physical energy, drill gamma, residual을 blocking invariant로 확인한다. |
-| `patch_test` | Green-Lagrange direct strain과 MITC tied shear가 같은 trial geometry와 같은 first/second variation을 써야 한다. | membrane, bending, twist, transverse-shear patch를 linear limit와 finite valid trial perturbation에서 각각 확인한다. |
-| `symmetry` | applied nodal moment가 없으면 physical/drill tangent는 exact arithmetic에서 symmetric이다. Fixed-spatial moment work tangent는 일반적으로 nonsymmetric이다. | no-moment case만 scaled symmetry check 대상으로 두고, moment case를 임의 symmetrization하지 않는다. |
-| `positive_definiteness` | nonlinear tangent는 load state, compression, near-buckling에서 indefinite일 수 있다. Positive definiteness는 일반 gate가 아니다. | stress-free constrained linear limit의 nonsingular solve와 singular negative case를 분리하고, factorization failure를 숨기지 않는다. |
-| `hourglass` | S4/S4R 모두 `2 x 2 x 2` full integration이므로 one-point reduced hourglass path는 승인 범위 밖이다. | source type으로 reduced/selective integration 또는 hourglass stabilization을 선택하지 않는 unit/integration test가 필요하다. |
-| `shear_locking` | MITC shear tying은 transverse-shear locking을 완화하지만 모든 thin-shell mesh에서 locking-free를 보장하지 않는다. | patch/reference evidence를 blocking으로 두고 broader thin/thick convergence는 nonblocking characterization으로 둔다. |
-| `volumetric_locking` | approved plane-stress shell, St. Venant-Kirchhoff-type material restriction에서는 `N/A`다. | 3-D incompressible material 또는 `nu >= 0.5` 의미로 확장하지 않는다. |
-| `membrane_locking` | original-style MITC4는 curved/distorted nonlinear meshes에서 membrane locking 위험이 남는다. | known limitation으로 기록한다. MITC4+ 성능 또는 Abaqus S4/S4R internal equivalence를 주장하지 않는다. |
-| `distortion` | positive Jacobian이라도 severe distortion/warpage는 conditioning과 stress accuracy를 악화할 수 있다. | 모든 Gauss/tying/center/recovery location의 finite, positive predicate를 fail-closed로 적용한다. 추가 quality cutoff는 요구하지 않는다. |
-| `singular_jacobian` | `J0 <= 0`, `j <= 0`, invalid reciprocal basis, invalid polar stretch는 residual/tangent를 무효화한다. | failed location을 omit/average/clamp/repair하지 않고 model/trial failure로 처리한다. |
-| `conditioning` | thin shells, small fixed drill scale, near-mechanism constraints는 Kff conditioning을 악화시킬 수 있다. | scaled matrix diagnostics만 사용하고 solver regularization/fallback으로 singularity를 숨기지 않는다. |
-| `convergence` | Full Newton은 same-trial consistent tangent에 의존한다. No line search/cutback이므로 difficult step은 deterministic nonconvergence가 될 수 있다. | NSNR-069/070 four-channel gates, iteration `1..100`, nonfinite rejection, no hidden retry를 integration tests로 고정한다. |
+| `rigid_body_modes` | Physical/internal/drill energy는 finite rigid motion에서 objective하고 pure drill만 regularized 되어야 한다. | finite rigid superposition에서 strain, stress, physical energy, drill gamma/energy와 residual covariance를 blocking invariant로 확인한다. |
+| `patch_test` | Green-Lagrange direct strain과 MITC tied shear는 같은 trial 및 first/second variation을 써야 한다. | membrane, bending, twist, transverse-shear patch와 linear limit을 확인한다. |
+| `symmetry` | Applied nodal moment가 없으면 physical/drill tangent는 exact arithmetic에서 symmetric이다. Fixed-spatial moment work tangent는 일반적으로 nonsymmetric다. | no-moment case만 scaled symmetry gate를 적용하고 moment case는 derivative consistency로 검증한다. |
+| `positive_definiteness` | Nonlinear tangent는 compression/near-buckling에서 indefinite일 수 있다. | positive definiteness를 global gate로 만들지 않고 singular/malformed tangent와 물리적 indefiniteness를 구분한다. |
+| `hourglass` | S4/S4R 모두 `2 x 2 x 2` full integration이며 reduced/hourglass path는 범위 밖이다. | source label로 integration 또는 stabilization을 바꾸지 않는 test가 필요하다. |
+| `shear_locking` | MITC shear tying은 transverse-shear locking을 완화하지만 general locking-free를 보장하지 않는다. | patch/reference evidence를 blocking으로, broader thin/thick study를 characterization으로 둔다. |
+| `volumetric_locking` | approved plane-stress shell과 `nu < 0.5` 범위에서는 `N/A`다. | 3-D incompressible behavior claim으로 확장하지 않는다. |
+| `membrane_locking` | original-style MITC4는 curved/distorted nonlinear mesh에서 membrane locking 위험이 남는다. | known limitation으로 보존하고 MITC4+ 또는 Abaqus 내부 성능을 상속한다고 주장하지 않는다. |
+| `distortion` | positive Jacobian만으로 accuracy는 보장되지 않지만 별도 calibrated quality cutoff는 승인되지 않았다. | 모든 Gauss/tying/center/recovery location을 fail-closed 검사한다. |
+| `singular_jacobian` | `J0<=0`, `j<=0`, invalid reciprocal basis/polar stretch는 residual/tangent를 무효화한다. | failed point를 omit, average, clamp 또는 repair하지 않는다. |
+| `conditioning` | thin geometry, small fixed drill scale와 near mechanism은 conditioning을 악화시킨다. | scale-aware diagnostics를 쓰고 hidden regularization/fallback을 금지한다. |
+| `convergence` | Full Newton은 same-trial consistent tangent에 의존하고 line search/cutback이 없다. | NSNR-069/070, four-channel AND, iteration `1..100`, finite-first와 no retry를 고정한다. |
+| `reaction_distribution` | local nodal support distribution은 element formulation/mesh/stabilization에 민감하다. | exact local error report는 유지하되 global balance/free residual만 blocking한다. |
 
 ## 5. Consistency Checks
 
 | check | result | evidence |
 | --- | --- | --- |
-| units and dimensions | `pass` | Translation/force, rotation/moment, stress/resultant dimensions are separated. Convergence channels keep force, force-length, length and dimensionless rotation separate. |
-| signs and residual convention | `pass` | Global residual is `f_int - f_ext`; constrained full residual is reaction and free residual is equilibrium evidence. Fixed-global dead force has no configuration derivative. |
-| DOF ordering and free/constrained assumptions | `pass` | Per-node global order is `[UX, UY, UZ, URX, URY, URZ]`; Newton solve uses stable free coordinates with `Delta q_c = 0`. Valid `0 x 0` free system is trivial success. |
-| coordinate transforms | `pass` | `Q=Exp(phi^)Q0`, left-spatial update, `J_l` variation, physical swing map and spatial reaction moment conversion are explicitly defined. |
-| kinematic operator / B matrix | `pass` | Green-Lagrange strain, MITC shear projection and both first/second variations use the same trial identity. |
-| constitutive contract | `pass` | Constant symmetric `C5` maps engineering Green-Lagrange strain to second Piola-Kirchhoff stress; no material history is introduced. |
-| Jacobian rules | `pass` | Fixed reference `J0` is integration measure; current `j` and `det F_c` are validity checks. Failed locations are not skipped. |
-| integration policy | `pass` | S4 and S4R share four midsurface Gauss points times two thickness points; reduced/selective integration is prohibited. |
-| residual/tangent consistency | `pass` | Complete tangent includes material, geometric, map-Hessian, objective drill Hessian and fixed-spatial moment work derivative terms. |
-| tangent symmetry expectation | `pass` | Symmetric only for conservative no-applied-moment case; generally nonsymmetric moment tangent must remain unsymmetrized. |
-| output locations | `pass-with-handoff` | Nodal U/UR/RF/RM and shell stress/resultant logical quantities are defined; exact HDF5 projection remains I/O-owned. Current nodal SPOS/SNEG stress CSV는 Gauss direct recovery와 일대일 대응하지 않으므로 external numerical comparison은 N/A다. |
+| units and dimensions | `pass` | Translation residual/reaction은 force, rotation residual/reaction moment는 force-length다. Force와 moment family 및 norm scale을 혼합하지 않는다. |
+| signs | `pass` | `r=f_int-f_ext`; constrained entry는 reaction, free entry는 equilibrium evidence다. Balance는 `applied+reaction`이고 reaction resultant는 reaction만 합한다. |
+| DOF ordering | `pass` | Global node order `[UX,UY,UZ,URX,URY,URZ]`; stable free/constrained partition과 `Delta q_c=0`을 보존한다. |
+| coordinates and moment conversion | `pass-with-handoff` | Global origin `[0,0,0]`, current arm `X+u`, spatial moment `J_l(phi)^(-T) r_phi`가 승인 의미다. `AUDIT-001` 구현 projection audit가 남는다. |
+| kinematic operator | `pass` | Green-Lagrange strain, MITC shear projection 및 first/second variation은 same-trial identity다. |
+| constitutive contract | `pass` | Constant symmetric `C5`가 fixed-reference engineering strain을 second Piola-Kirchhoff stress로 매핑하며 material history가 없다. |
+| Jacobian rules | `pass` | Fixed `J0`가 integration measure, current `j`와 `det(Fc)`가 validity predicate다. |
+| integration | `pass` | S4/S4R 공통 four midsurface by two thickness points; reduced/selective integration은 금지한다. |
+| residual/tangent | `pass` | Material/geometric/map-Hessian/drill/moment-work derivative가 complete same-trial tangent를 이룬다. |
+| recovery locations | `pass-with-handoff` | Nodal U/UR/reaction 및 Gauss direct shell recovery logical meaning은 정의되었다. Final dataset projection은 I/O-owned다. |
+| reference identity | `pass` | Case/state/instance/source label/component로 match하고 row order를 identity로 쓰지 않는다. |
 
 ## 6. Verification Readiness
 
-### Blocking internal numerical tests
+### 6.1 Blocking internal numerical tests
 
-Implementation Planning shall carry these as feature-required tests before any reference-comparison success claim:
+기존 승인 수치 portfolio를 유지한다.
 
-Mixed translation/rotation 검사는 fixed-reference characteristic length
-`L=max(||X_I-X_J||)`와 node block `Dq=diag(L I3,I3)`를 사용한다. Tangent test direction은
-`||p_hat||inf=1`, perturbation은 `q +/- h Dq p_hat`으로 두고
-`h={1e-3,3e-4,1e-4,3e-5,1e-5,3e-6,1e-6,3e-7}` 전부를 검사한다. Roundoff plateau 전
-최소 두 interval에서 centered-difference observed order `>=1.5`이고 한 interior point가
-scaled error `<=1e-6`여야 한다. Single-`h` 우연 통과는 허용하지 않는다.
+1. Stress-free `q=0` linear MITC4 residual/tangent/recovery와 physical/drill split.
+2. `||Q^TQ-I||_F<=1e-12`, `|det(Q)-1|<=1e-12`, `d=Qe3` 및 branch margin.
+3. Mixed translation/rotation scaled tangent directional derivative schedule와 interior scaled
+   error `<=1e-6`; zero analytical direction `<=1e-10`.
+4. No-applied-moment scaled tangent symmetry `<=1e-12`; applied moment는 derivative
+   consistency만 검사한다.
+5. Finite rigid objectivity의 scaled physical strain/stress/energy/drill/residual `<=1e-10`.
+6. Membrane/bending/twist/shear patch, component order와 bottom/top stress sign.
+7. Fixed-global force/moment identity, `rho_M<=1e-12`, absolute prescribed path와 zero
+   constrained Newton correction.
+8. Exact fixed-factor sequence, factor one, iterations `1..100`, pass at 100, no 101/cutback/retry.
+9. NSNR-069/070의 finite-first exact-zero/nonzero branches, inclusive thresholds와 four-channel AND.
+10. Trial/recovery/solve/output failure rollback과 deterministic assembly/frame/row/diagnostic order.
 
-1. Linear limit: at stress-free `q=0`, nonlinear element residual/tangent/recovery reduce to approved linear MITC4 signs, `2 x 2 x 2` integration and physical/drill split.
-2. Rotation state invariants: every committed/trial `Q` satisfies `||Q^T Q-I||_F <= 1e-12`,
-   `|det(Q)-1| <= 1e-12`, and `d=Q e3`. Global/swing/twist `pi` branch angular margin은
-   `sqrt(epsilon_double)`, 약 `1.4901161193847656e-8` rad보다 커야 한다.
-3. Tangent directional derivative: compare `Dq^T K_T Dq p_hat` with the central
-   residual derivative under the schedule above in separated force and moment channels.
-   Zero analytical directions require exact-zero construction and scaled absolute error
-   `<=1e-10`; nonfinite metric은 허용하지 않는다.
-4. No-moment tangent symmetry: after work-conjugate congruence `Dq^T K_T Dq`, no-applied-moment
-   tangent scaled Frobenius symmetry error `<=1e-12`; applied fixed-spatial moment cases are checked for
-   exact derivative consistency, not symmetry.
-5. Finite rigid objectivity: superposed finite rigid motion leaves physical strain/stress,
-   physical energy, drill gamma/energy and internal residual at scaled `<=1e-10` levels.
-6. Patch/sign recovery: membrane, bending, twist and transverse shear patch states preserve
-   component order and bottom/top stress signs.
-   Analytical strain/resultant/stress error is relative `<=1e-9`.
-7. Load and boundary path: fixed-global force/moment source identity, `rho_M <= 1e-12`
-   rejection/projection, absolute factor-one boundary path and zero constrained Newton
-   correction are tested independently.
-8. Newton lifecycle: factor identities use ordinal `j*h` values strictly below one,
-   followed by one exact assigned `1.0`; cumulative `lambda += h`와 tolerance-based duplicate
-   endpoint는 금지한다. For `shellNL` the expected intended factors are `0.1, 0.2, ...,
-   1.0`. Iterations are `1..100`, pass at `100` is allowed, iteration `101` is forbidden.
-9. Convergence gates: NSNR-069/070 four-channel inclusive `<=` rules, typed zero-scale
-   `1e-3` thresholds and nonfinite rejection are tested without adding energy or line-search gates.
-10. Commit/rollback and determinism: failed trial, recovery, solve or output does not mutate
-    the prior committed state or prior authoritative final result; row/diagnostic order is stable.
+### 6.2 Factor-one blocking equilibrium contract
 
-### Downstream reference comparisons
+각 nonlinear case의 accepted factor-one state에 대해
 
-The required stored-reference cases and logical quantities are defined in
-`docs/nonlinear-static-newton-raphson/reference-model.md`.
+\[
+\mathbf a_{F,I}=\mathbf F_I^{appl},\qquad
+\mathbf c_{F,I}=\mathbf F_I^{react},
+\]
 
-- `shellnl-s4-final` is the primary nonlinear external reference at accepted factor one.
-- `shell-s4-linear-limit` is the read-only linear-limit/reference-identity regression for the

-External comparison uses only accepted-state quantities and `docs/TOLERANCE.md`. Missing,
-extra, duplicate or nonfinite required rows fail before tolerance. The comparison result itself
-is Implementation Agent ownership.
+를 stable source-node order로 계산한다. `x=X+u`이고 applied physical moment는 formulation
+§13.4의 effective physical-work moment다. Define
+
+\[
+\mathbf e_F=\sum_I(\mathbf a_{F,I}+\mathbf c_{F,I}),\quad
+S_F=\max\left(\sum_I\|\mathbf a_{F,I}\|_2,
+               \sum_I\|\mathbf c_{F,I}\|_2\right),

+S_M=\max\left(\sum_I\|\mathbf a_{M,I}\|_2,
+               \sum_I\|\mathbf c_{M,I}\|_2\right).
+\]
+
+Force와 moment는 각각 `rho_F=||e_F||2/S_F`, `rho_M=||e_M||2/S_M`로 검사하고 둘 다
+`<=1e-8`이어야 한다. 이 threshold는 승인된 nonlinear acceptance value이며,
+unclamped sum-of-contribution scale과 dimension-separated form은 승인된 linear MITC4
+global-equilibrium convention을 유지한다. `S=0`이면 balance도
+exact zero일 때만 `0`, 아니면 fail하며 absolute floor, `max(1,S)` 또는 zero clamp를 두지 않는다.
+
+Accepted free residual은 cross-unit combined norm을 만들지 않는다. Factor-one accepted trial의
+free translation-force와 free rotation-moment rows가 각각 NSNR-069의 exact gate를 다시
+재현해야 한다: matching external scale이 nonzero이면 approved infinity-norm relative gate
+`<=1e-2`, exact zero이면 typed absolute `<=1e-3` force 또는 force-length다. 두 channel 모두
+finite-first로 통과해야 한다.

 ## 7. Required Revisions
 
 ### Formulation Agent
 
-None before I/O Definition. The current formulation is numerically sufficient for the I/O
-contract. Current source element/node SPOS/SNEG stress CSV에 맞추기 위한 extrapolation,
-averaging 또는 새 recovery 의미는 추가하지 않는다.
+없음. §11.4/§13.4의 reaction, spatial moment와 global balance 의미는 revised requirements를
+충족한다.
 
 ### Research Agent
 
-None before I/O Definition. Public large-response benchmarks and shell MMS remain useful future
-evidence, but the current Stage 4 gate does not require another research pass.
+없음. Stored fine-mesh case와 internal invariant portfolio가 이번 I/O gate에 충분하다.
 
 ### I/O Definition Agent
 
-Define parser/semantic/HDF5/log projection for the logical quantities and row identities in
-`reference-model.md`. Preserve the split between blocking internal nonlinear tests and external
-stored reference comparison; do not claim Abaqus internal equivalence.
+`reference-model.md`의 logical quantities와 source identity를 최종 projection으로 연결한다.
+`AUDIT-001`의 balance error, constrained reaction resultant, accepted free residual을 별도
+quantity로 유지한다. Current-arm/spatial-moment semantics와 factor-one identity를 보존하고
+local RF/RM review-only disposition을 blocking으로 되돌리지 않는다.

-- Preserve required source identity: case, accepted state, instance, node label and component.
-  Stress artifact의 element/node/section identity와 stored element-label order는 read-only
-  inventory로 보존하되 FESA comparison row로 합성하지 않는다.
-- Keep `U1/U2/U3` blocking and `UR1/UR2/UR3` warning-only. For `shellNL`, compare

-  families from `reference-model.md`. `RM3`와 stress는 comparison에서 제외한다.
-- Apply `docs/TOLERANCE.md` exactly; do not add an independent absolute floor, row averaging,
-  source-order matching, or calibration gate.
-- Treat `shellNL` as weak but valid nonlinear final-state reference evidence; require the
-  blocking internal tests above for tangent/objectivity/rollback/finite-rotation correctness.
+- `pass-for-io-definition`; blockers: 없음.
+- External families는 `docs/TOLERANCE.md`를 그대로 사용한다. Independent absolute floor,
+  averaging, collapse, source-order matching, clamp 또는 calibration gate를 추가하지 않는다.
+- Internal factor-one global force/moment balance는 Section 6.2의 dimension-separated normalized
+  `1e-8` gate, accepted free residual은 NSNR-069 force/moment gate를 사용한다.
+- Fine primary와 coarse companion nonlinear cases 모두 U blocking/UR warning-only를 유지한다.
+- Post-closure `shellnl-meshfine-02-s4-final`도 같은 U/UR 및 local RF/RM disposition을 사용하되,

+HDF5는 `reference-comparison.md`에 적힌 build-local exact path에서 직접 읽었다. Optional FESA
+debug CSV view는 선언되거나 필요하지 않아 사용하지 않았다. Factor-one
+`nodal/displacement`, `global/equilibrium`, `global/energy`, direct shell stress와
+`accepted_frames`를 확인했다.
+
+### 2.3 Read-only reference evidence
+
+Canonical reference bundle은 `reference-comparison.md`가 inventoried한 12개 exact file을 사용했다.
+
+- `reference/shellNL-meshfine/`: input, displacement, reaction, stress inventory
+- `reference/shellNL/`: input, displacement, reaction, stress inventory
+- `reference/shell/`: linear input, displacement, reaction inventory, stress inventory
+
+각 SHA-256은 `reference-model.md`와 `reference-comparison.md` inventory에 일치한다. 비교량은
+fine/coarse/linear `U1/U2/U3` blocking, `UR1/UR2/UR3` warning-only, fine/coarse local
+`RF1/RF2/RF3`와 physical spatial `RM1/RM2` review-only다. `RM3`와 stored element-corner
+stress는 numerical comparison에서 제외되었다.
+
+Reference model의 목적은 중앙 `DOF 3=-100000` fixed-global dead load를 받고 둘레의 all-six
+DOF가 고정된 `10 x 10`, thickness `0.5` square plate의 coarse/fine nonlinear response와
+linear-limit source identity를 검증하는 것이다. Nonlinear cases는 `0.1` 간격으로 factor one까지
+진행한다.
+
+## 3. Physics Checks
+
+| physics check | result | evidence and interpretation |
+| --- | --- | --- |
+| global equilibrium | `pass` | Fine normalized force `2.09625758e-12`, moment `2.74546602e-10`; coarse force `8.25122661e-12`, moment `1.41375091e-10`. 네 값 모두 approved inclusive `<=1e-8`다. HDF5 `/global/equilibrium`은 `location=global-balance-error`, current arm, global origin `[0,0,0]`, spatial moment 의미를 가진다. |
+| reaction consistency | `pass` | Applied `F3=-100000`에 대해 constrained-reaction resultant `F3`는 fine/coarse 모두 약 `+100000`이고 다른 force components는 roundoff 수준이다. Applied-plus-reaction force/moment와 accepted free force/moment residual이 각각 blocking gate를 통과했다. Local RF/RM six-family discrepancy는 승인 계약상 review-only nodal redistribution evidence이며 global reaction/resultant identity를 대체하지 않는다. |
+| displacement direction | `pass` | Downward load에 대해 node 2 final `U3`는 fine `-2.56338e-5`, coarse `-2.35504e-5`; reference도 각각 `-2.57957054e-5`, `-2.37408203e-5`다. HDF5 path는 factor `0.1..1.0`에서 fine `-2.56338e-6 .. -2.56338e-5`, coarse `-2.35504e-6 .. -2.35504e-5`로 부호 반전·jump·rollback 없이 진행한다. |
+| symmetry / expected zero | `pass` | Center node 2의 factor-one `U1/U2`와 rotations는 fine/coarse에서 약 `1e-17` 이하로, centered load와 symmetric all-edge constraint의 expected-zero response와 일치한다. Fresh physics-focused CTest에서 finite rigid objectivity, zero internal force, rigid translation nullspace와 no-moment tangent symmetry checks가 통과했다. |
+| element force balance | `covered-by-approved-invariants` | 승인 HDF5에는 standalone element nodal-action balance dataset이 없고 external element-force comparison도 요구되지 않는다. 대신 complete element residual/tangent same-trial identity, patch recovery, stable assembly covariance tests와 accepted global/free equilibrium gate가 문서화된 expectation을 충족한다. 별도 element-force output을 invent하지 않았다. |
+| stress/strain | `pass-sanity-evidence` | HDF5 direct fixed-reference Gauss stress는 finite다. Element 1/GP1의 `[S11,S22,S12]`는 fine bottom `[-264846,-77843.6,914.879]`, middle `[1.94695,0.530775,-0.0224511]`, top `[264850,77844.8,-914.925]`; coarse도 bottom/top sign이 반대이고 middle이 작아 centered plate bending sign/thickness pattern과 일치한다. Stored CSV는 corner/SPOS-SNEG identity로 위치가 달라 numerical stress comparison이 승인되지 않았으므로 이를 tolerance pass로 재분류하지 않는다. |
+| rigid body mode | `pass` | 둘레 all-six-DOF support가 global rigid-body motion을 제거하고, accepted path에 비정상 large translation 또는 singular/nonfinite 증상이 없다. Fresh focused tests에서 proper triad/director, finite rigid objectivity, zero internal force, rigid nullspace와 invalid branch rejection을 확인했다. |
+| energy/residual | `pass-sanity-evidence` | Factor-one physical strain energy는 fine `1.28169`, coarse `1.17752`로 finite positive이며 near-linear relation `0.5*100000*abs(U3_center)`와 일치한다. 이는 secondary sanity evidence이고 승인 energy convergence gate는 아니다. Fine/coarse accepted free force/moment residual은 NSNR-069 blocking gate를 통과했고 log에는 nonfinite/failed accepted state가 없다. |
+| model coverage | `pass` | Fine 729-node/676-element primary, coarse 49-node/36-element companion, linear control과 internal linear-limit/tangent/objectivity/patch/rollback portfolio가 승인 NSNR-030 scope를 덮는다. Stored response는 weak geometric-nonlinear regime이고 original-style MITC4의 curved/distorted membrane-locking risk는 알려진 한계지만 Numerical Review가 이번 release의 additional benchmark/convergence gate로 승인하지 않았으므로 model-coverage gap을 새로 만들지 않는다. |
+
+Fresh physics-focused verification command:
+
+```powershell
+ctest --preset windows-msvc-ninja-debug -R '^(NonlinearMitc4Shell|NonlinearMitc4Recovery|NonlinearMitc4Residual|NonlinearMitc4Tangent|NonlinearMitc4Objectivity|NonlinearMitc4Patch|FiniteRotation|NonlinearStaticProcedure)\.' --output-on-failure
+```
+
+Result: `23/23` passed, exit `0`, total real time `5.12 s`.
+
+## 4. Failure Classification
+
+- blocking classification: 없음
+- resolved finding: `PHYS-STATUS-001`; corrected `reference-comparison.md`가 required overall
+  `pass-for-physics-evaluation` handoff와 detailed
+  `blocking-pass-with-review-only-findings` verdict의 관계를 명시했다.
+- observed failures: `equilibrium-failure`, `reaction-inconsistency`,
+  `displacement-direction-failure`, `symmetry-failure`, `stress-location-failure`,
+  `element-force-inconsistency`, `rigid-body-mode-suspected`, `nonfinite-result`,
+  `model-coverage-gap`, `upstream-contract`, `environment` 모두 없음.
+
+## 5. Evaluation Verdict
+
+- verdict: `pass-for-release-agent`
+- physics evidence disposition: documented equilibrium, reaction, displacement, symmetry/objectivity,
+  stress/strain sanity, rigid-body, residual/path and model-coverage checks show no physical failure.
+- pass disposition: documented physical expectations passed and no physics/model-coverage/I/O/upstream
+  blocker remains.
+- release meaning: this verdict authorizes Release Agent evaluation through Coordinator only. It is
+  not Release approval, publish/deploy/package/tag authorization, or external-solver equivalence.
+
+## 6. Handoff Recommendation
+
+- handoff: `Release Agent`, always through `Coordinator Agent`
+- recommendation: Release Agent는 current approved hashes, Stage 6
+  `pass-for-physics-evaluation`, 이 문서의 `pass-for-release-agent`, known limitations와
+  review-only findings를 사용해 release readiness만 audit한다.
+- boundary: Physics Evaluation Agent는 release readiness, final release checklist, release notes,
+  publish/deploy/package/tag를 승인하지 않는다.
+
+## 7. No-Change Assertion
+
+이 Stage 7 작업은 `docs/nonlinear-static-newton-raphson/physics-evaluation.md`만 생성했다.
+Source code, tests, CMake, Harness, requirements, research, formulation, numerical review,
+reference model, I/O contract, implementation reports, reference artifacts와 tolerance policy를
+수정하지 않았다. Abaqus, Nastran 또는 다른 reference solver를 실행하지 않았다.
+
+## 8. Open Issues
+
+| id | severity | issue | gate effect |
+| --- | --- | --- | --- |
+| `PHYS-META-001` | nonblocking | `requirements.md`의 draft/pending metadata가 authoritative Coordinator/user reapproval record와 stale함 | 현재 hash의 explicit approval로 physics authority는 해소됨; Release traceability audit에서 투명하게 유지 |
+| `PHYS-LOCAL-001` | nonblocking | six local RF/RM families have review-only discrepancies | approved disposition 유지; global force/moment balance와 free residual을 blocking evidence로 사용 |
+| `PHYS-STRESS-001` | nonblocking | stored corner/SPOS-SNEG stress와 FESA direct Gauss recovery 위치가 다르고 fine optional stress row 하나의 node label이 malformed | stress numerical comparison 제외 유지; artifact를 repair하지 않음 |
+| `PHYS-LIMIT-001` | known limitation | stored cases are weak geometric-nonlinear plate responses; original MITC4 has known curved/distorted membrane-locking risk | approved current portfolio에서는 blocker 아님; broader claim 금지 |

+# Nonlinear Static Newton-Raphson Reference Comparison
+
+## Verdict
+
+`blocking-pass-with-review-only-findings`. FESA HDF5 is the authoritative solver output. The
+Abaqus CSV files are read-only external comparison evidence; the observed agreement does not imply
+Abaqus S4 internal formulation, integration, stabilization, or recovery equivalence.
+
+Overall handoff status: `pass-for-physics-evaluation`. This handoff classification records that
+all blocking comparisons passed; the detailed verdict above remains
+`blocking-pass-with-review-only-findings` because the six local RF/RM findings are review-only.
+
+The literal execution order was `ARTIFACT CHECK -> COMPARE -> CLASSIFY -> REPORT`.
+
+The `COMPARE` commands were
+`ctest --preset windows-msvc-ninja-debug -R "^NonlinearStaticReference\." --output-on-failure`
+(exit 0, 905.404 s, 9/9 passed), followed by
+`ctest --preset windows-msvc-ninja-debug -R "^(NonlinearStaticReference|ReferenceTolerance|Mitc4Reference)\." --output-on-failure`
+(exit 0, 930.617 s, 9/9 matched tests passed). The fresh full CTest run then passed 302/302;
+its command and output tail are recorded in `build-test.md`.

 ## 2. Reference Acceptance Scope
 
-Required scope는 두 stored case다.
+승인 closure 계약의 세 stored case를 유지하고 merge 후 별도 검증할 한 case를 추가한다.
 
-- `shellnl-s4-final`: `nlgeom=YES` nonlinear static S4 final accepted state를 비교하는
-  primary external reference case.
-- `shell-s4-linear-limit`: 같은 S4 mesh의 `nlgeom=NO` read-only linear-limit/reference-identity
-  regression case. 이 case는 nonlinear response evidence가 아니며, 현재 stress CSV의 element-label
-  ordering을 row-order matching으로 사용하지 않는다.
+- `shellnl-meshfine-s4-final`: 사용자가 추가하고 검증을 요청한 729-node/676-element
+  mesh-refined nonlinear primary case. External `U1/U2/U3`와 factor-one internal equilibrium은
+  blocking이다.
+- `shellnl-s4-final`: 49-node/36-element coarse nonlinear companion regression. Fine case와
+  별도 reference에 대해 external `U1/U2/U3`와 factor-one internal equilibrium을 blocking으로
+  검증한다.
+- `shell-s4-linear-limit`: 같은 coarse topology의 `NLGEOM=NO` linear-limit/source-identity
+  regression. Nonlinear response evidence로 부르지 않는다.
+- `shellnl-meshfine-02-s4-final`: 729-node/676-element post-closure nonlinear additive case.
+  과거 canonical Stage 6 `reference-comparison.md`에는 포함되지 않았으며 merge된 current code로
+  별도 verification한다. 이 pending comparison은 기존 세 case의 승인 gate 또는 Release verdict를
+  소급 변경하지 않는다.
 
-`shellNL`은 final-state reference comparison에는 충분하지만 weak nonlinear response다. Dominant
-`U3`/stress 값이 linear case와 거의 같으므로 finite-rotation objectivity, consistent tangent,
-commit/rollback과 convergence lifecycle은 `numerical-review.md`의 blocking internal tests로 검증한다.
+모든 selected case에서 displacement `U1/U2/U3`는 blocking, `UR1/UR2/UR3`는
+warning-only다. Coarse/fine/post-closure local nodal `RF1/RF2/RF3`와 physical spatial `RM1/RM2`는
+common external policy로 exact error/precheck evidence를 만들되 review-only이고 전체 blocking
+verdict를 바꾸지 않는다. Local `RM3`와 stress는 numerical comparison에서 제외한다.
 
-## 3. Reference Case Inventory with exact input and required CSV paths
+Coarse와 fine은 각자의 input/CSV에 독립적으로 비교한다. 두 mesh 사이 node interpolation,
+row pairing, averaging, collapse, observed convergence order 또는 direct coarse/fine equality
+gate를 만들지 않는다. Fine case 추가는 Abaqus S4와 FESA MITC4의 element formulation,
+integration, stabilization 또는 internal behavior equivalence를 의미하지 않는다.
+`shellnl-meshfine-02-s4-final`도 자기 input/CSV에만 독립적으로 비교하고 기존 fine case와
+cross-case equality 또는 mesh-convergence gate를 만들지 않는다.

 ## 4. Source Identity and Component Contract
 
-### 4.1 Accepted-state identity
+### 4.1 Case and accepted-state identity
 
-- Abaqus identifiers are case-insensitive semantic identities. Input spelling
-  `Part-1-1` and CSV spelling `PART-1-1` match as one instance while original text is
-  retained in artifacts and reports; no file or row is rewritten.
-- `shellnl-s4-final` rows require exact CSV `Frame` value
-  `Increment     10: Step Time =    1.000`, mapped logically to the accepted factor-one state.
-- `shell-s4-linear-limit` rows have no `Frame` column and map to the single final static state.
-- Row order is never a matching identity. It may only be used for deterministic reporting after
-  source keys are matched.
+- Instance identity는 case-insensitive semantic match다. Artifact spelling `Part-1-1`과
+  `PART-1-1`은 같은 instance이지만 file text를 rewrite하지 않는다.
+- 세 nonlinear case required rows의 exact CSV Frame은
+  `Increment     10: Step Time =    1.000`이며 accepted factor-one state에 대응한다.
+- Linear case에는 `Frame` column이 없고 single final static state로 해석한다.
+- Row order는 identity가 아니다. Stable key match 후 deterministic reporting order로만 정렬한다.
 
-### 4.2 Nodal displacement contract
+### 4.2 Nodal displacement and rotation
 
-Required mapping is `U-U1/U-U2/U-U3 -> U1/U2/U3` and
-`UR-UR1/UR-UR2/UR-UR3 -> UR1/UR2/UR3`. U is global length; UR is the
-dimensionless fixed-initial global rotation-vector output. Logical key is
+CSV `U-U1/U-U2/U-U3`는 logical `U1/U2/U3`, `UR-UR1/UR-UR2/UR-UR3`는
+logical `UR1/UR2/UR3`에 대응한다. Key는
 
 ```text
 (case_id, accepted_state, canonical_instance_name, source_node_label, component)
 ```
 
-Both cases require source node labels `1..49` exactly once. U components form one
-blocking translation family and UR components form one warning-only rotation family,
-preserving the project MITC4 classification.
+이다. Coarse/linear은 labels `1..49`, fine과 post-closure `_02`는 `1..729`를 각각 정확히 한 번 요구한다.
+U는 global length/blocking, UR은 fixed-initial global rotation-vector/warning-only다.
 
-### 4.3 Nonlinear reaction contract
+### 4.3 Local reaction review contract
 
-Reaction comparison applies only to `shellnl-s4-final` and only to the input boundary
-`Set-2` nodes:
+Reaction source rows는 input `Set-2` constraint mask로 선택한다.
 
-```text
-1,3,4,5,6,7,8,9,14,15,16,17,22,23,24,25,26,27,28,29,30,31,32,33
-```
+- coarse: `1, 3..9, 14..17, 22..33` — 24 nodes, all six DOFs constrained.
+- fine: `1, 3..9, 34..57, 82..153` — 104 nodes, all six DOFs constrained.
+- post-closure `_02`: fine과 같은 exact `Set-2` inventory — 104 nodes, all six DOFs constrained.
 
-All six global components are constrained at these 24 nodes. Other CSV node rows remain
-part of file/schema/finite inventory but are not numerical reaction rows: FESA free entries
-are equilibrium residual evidence, not Abaqus free-node zero reactions.
+다른 CSV node rows는 file/schema/finite inventory지만 local reaction numerical rows가 아니다.
+Free FESA entries는 reaction이 아니라 accepted free residual evidence다.
 
-| CSV components | logical quantity | FESA meaning | disposition |
+| CSV components | logical quantity | matching FESA meaning | disposition |
 | --- | --- | --- | --- |
-| `RF-RF1`, `RF-RF2` | fixed-initial shell-plane reaction force | constrained translational full residual, global force | blocking family |
-| `RF-RF3` | fixed-initial transverse reaction force | constrained translational full residual, global force | blocking family |
-| `RM-RM1`, `RM-RM2` | tangent-plane spatial reaction moment | `J_l(phi)^(-T)` conversion of the constrained generalized reaction, global force-length | blocking family |
-| `RM-RM3` | director/drilling-axis reaction review value | stabilization-dependent; no physical external equivalence target | excluded |
+| `RF-RF1`, `RF-RF2` | in-plane local reaction force | constrained translational full residual, global force | `review-only` |
+| `RF-RF3` | transverse local reaction force | constrained translational full residual, global force | `review-only` |
+| `RM-RM1`, `RM-RM2` | tangent-plane physical reaction moment | constrained generalized residual converted by `J_l(phi)^(-T)`, global spatial force-length | `review-only` |
+| `RM-RM3` | director/drilling-axis row | no approved physical external equivalence target | `excluded` |
 
-In-plane and transverse force are distinct model-fixed logical projections and therefore
-use distinct families. Raw generalized rotation-coordinate residual is not matched directly
-to the CSV `RM` value.
+Raw generalized rotational residual을 CSV RM에 직접 match하지 않는다. Review-only는 row omission을
+허용한다는 뜻이 아니다. Exact row precheck와 common-policy error/RMS를 모두 보고하되 그 결과가
+blocking verdict를 변경하지 않는다는 뜻이다.
 
-### 4.4 Stress review identity and comparison exclusion
+### 4.4 Distinct factor-one equilibrium quantities
 
-Stress rows have read-only identity
+각 nonlinear case에서 같은 accepted factor-one state를 사용한다.
+
+| logical quantity | source identity / projection | components | disposition |
+| --- | --- | --- | --- |
+| accepted free residual | input mask로 결정한 stable free `(instance,node,global DOF component)` rows; force와 moment channel 분리 | free `UX/UY/UZ`; free `URX/URY/URZ` generalized covectors | `blocking-internal` |
+| constrained reaction resultant | constrained source rows만 current arm과 spatial physical moment로 합산 | force `[1,2,3]`; moment `[1,2,3]` | `review-only-summary` |
+| applied-plus-reaction balance error | all resolved applied sources plus constrained reactions; global origin `[0,0,0]`; `x=X+u`; physical spatial nodal moments | force `[1,2,3]`; moment `[1,2,3]` | `blocking-internal` |
+
+Constrained reaction resultant force is `sum(F_react)`. Its moment is
+`sum(x cross F_react + M_react)`. Balance error adds the corresponding applied force and
+`x cross F_appl + M_appl`. Accepted free residual is neither sum. 세 quantity는 exact
+source/state identity를 공유하지만 interchangeable하지 않다.
+
+현재 stored case의 constrained prescribed `u=phi=0` 때문에 support current arm과 initial arm,
+generalized moment와 spatial moment가 수치적으로 일치한다. 이는 supported general nonzero
+prescribed translation/rotation에서 initial arm/raw rotational residual을 재사용할 근거가 아니다.
+
+### 4.5 Stress inventory and exclusion
+
+Stress inspection key는
 
 ```text
 (case_id, accepted_state, instance, element label,
  element-corner node label, SPOS/SNEG section surface, component)
 ```
 
-Every current element has its four connectivity nodes and one `SPOS` plus one `SNEG`
-row per node. The files are ordered in contiguous ascending element-label blocks `1..36`;

-The identity is nevertheless not the approved FESA recovery location: FESA emits direct
-`[S11,S22,S12]` at four midsurface Gauss locations and bottom/middle/top positions, without
-nodal extrapolation or averaging, and does not emit `S33`. Consequently no stress column

 ## 5. Row Prechecks
 
-Before tolerance, the comparator shall fail the affected comparison if any required condition
-below is false.
+Tolerance 또는 internal metric 전에 다음을 검사한다.
 
-1. Exact declared input path and every `required comparison artifact=yes` CSV path for the
-   case exist and are readable.
-2. Required headers are present after trimming surrounding whitespace from header names.
-3. `shellnl-s4-final` contains only the exact required `Frame` value for required rows.
-4. Wide CSV rows expand to component rows using the component contract in Section 4.
-5. Required source row keys are unique. Duplicate wide keys or duplicate expanded component keys fail.
-6. Displacement projection requires all 49 source nodes and declared components. Nonlinear
-   reaction projection derives the exact 24-node/component set from the input constraint mask;
-   it does not infer reaction identity from CSV zero values.
-7. FESA and reference required projected row-key sets are exactly equal: missing and extra rows
-   both fail.
-8. Every required numeric value is finite. Nonfinite required FESA or CSV value fails before tolerance.
-9. Optional stress inventory uses `(instance, element label, node label, section point)` and verifies
-   the current ascending element-label blocks, connectivity nodes and SPOS/SNEG pair. This inspection
-   does not create a stress equality gate.
-10. Required rows are not omitted, synthesized, normalized, averaged, sorted into a different identity,
-   zero-clamped, or repaired.
+1. 각 case의 exact declared input과 해당 disposition에 필요한 CSV가 존재하고 readable하다.
+2. Header는 surrounding whitespace만 trim하고 required names/components가 모두 있어야 한다.
+3. Nonlinear required rows의 Frame은 exact factor-one identity여야 한다.
+4. Wide CSV는 Section 4 contract로 component rows에 결정적으로 expand한다.
+5. Wide key와 expanded key는 unique해야 한다. Duplicate는 affected family를 tolerance 전에 fail한다.
+6. Input node inventory와 source constraint mask로 expected key set을 만든다. CSV zero values 또는
+   row position에서 reaction identity를 추론하지 않는다.
+7. FESA와 reference projected key sets는 exact equal해야 한다. Missing과 extra rows를 모두 fail한다.
+8. Required FESA/CSV/internal values와 derived scales/norms는 모두 finite여야 한다.
+9. Internal free residual rows는 exact free mask와 force/moment partition을 보존한다. Global balance는
+   모든 applied source와 constrained reaction을 stable source order로 한 번씩만 사용한다.
+10. Local review rows는 global resultant로 collapse하거나 대체하지 않는다. Review precheck failure는
+    deterministic review failure로 기록하지만 blocking verdict를 변경하지 않는다.
+11. Warning-only precheck/tolerance failure는 deterministic warning을 만들고 blocking verdict를
+    변경하지 않는다. Blocking precheck failure는 전체 comparison을 fail한다.
+12. Row omission/synthesis, averaging, source-order matching, clamp, normalization 또는 artifact repair를
+    허용하지 않는다.

 ## 6. Tolerance and Blocking/Warning Policy
 
-Use exactly `docs/TOLERANCE.md` for every external reference family. This report does not invent
-or calibrate tolerance values.
+### 6.1 External families
 
-For each comparison family:
+Section 4.6의 모든 external blocking, warning-only와 review-only error report는
+`docs/TOLERANCE.md`를 그대로 사용한다.
 
-- `S = max(abs(reference_value_i))`, using reference values only.
-- near-zero band is `0.01*S`.
-- if `abs(reference_value_i) <= 0.01*S`, row passes iff `abs(fesa-reference) <= 0.01*S`.
-- otherwise row passes iff relative error `<= 0.05`.
-- family relative RMS is `RMS(error)/S <= 0.01`.
-- no independent absolute-error floor, `max(1, S)` clamp, row omission, averaging, or zero clamp is allowed.
-- if `S = 0`, the family passes only when all FESA values are exactly zero; otherwise report
-  `zero-reference-scale-nonzero-error`.
+- Reference-only `S=max(abs(reference_i))`, near-zero band `B=0.01*S`.
+- `abs(reference_i)<=B`이면 `abs(fesa-reference)<=B`.
+- 그 외 row는 relative error `<=0.05`.
+- 모든 row와 `RMS(error)/S<=0.01`이 함께 pass해야 family가 pass한다.
+- Independent absolute floor, `max(1,S)`, omission, averaging 또는 zero clamp는 없다.
+- `S=0`이면 모든 FESA 값도 exact zero일 때만 pass한다.
 
-Families are separated by the exact case/logical quantities in Section 4.5. Current
-reference-only scales provide a reproducible reader/comparator audit:
+Observed reference-only scales는 reader/family audit evidence이며 calibration 값이 아니다.

-Any `blocking` family row or RMS failure fails the reference comparison for the feature.
-`warning-only` failures produce deterministic warning evidence but do not change the blocking
-verdict. `RM3` and stress artifacts create neither a blocking nor warning-only tolerance family.
+Blocking family의 precheck/row/RMS failure만 전체 external-reference verdict를 fail한다.
+Warning-only는 warning, review-only는 deterministic review finding/error table을 남기지만
+blocking verdict를 바꾸지 않는다. `RM3`와 stress는 family를 만들지 않는다.
+
+### 6.2 Internal equilibrium families
+
+- Accepted free force/moment residual은 factor-one accepted trial에서 NSNR-069을 그대로
+  재현한다. Nonzero matching external scale이면 infinity-norm relative `<=1e-2`; exact-zero
+  scale이면 typed absolute `<=1e-3` force 또는 force-length다.
+- Global force/moment balance는 `numerical-review.md` §6.2의 sum-of-contribution scale과
+  dimension-separated normalized metric을 사용하며 각각 `<=1e-8`이다.
+- Internal gate에 external family tolerance, absolute floor, reference-derived scale 또는 local
+  nodal reaction error를 섞지 않는다.
 
 ## 7. Open Issues and I/O Handoff
 
 Open issues blocking I/O Definition: 없음.
 
-I/O Definition Agent handoff:
+Post-closure verification status: `shellnl-meshfine-02-s4-final`은 artifact/schema/family contract가
+준비되었지만 과거 canonical Stage 6 comparison에는 포함되지 않았다. Merge된 current code의
+별도 실행과 comparison evidence는 Implementation Agent 소유이며 이 inventory는 pass/fail을
+선언하지 않는다. 이 pending evidence는 기존 feature closure 또는 Release verdict를 바꾸지 않는다.
 
-- Project only the comparison quantities in Sections 4.2, 4.3 and 4.5 to authoritative FESA
-  result datasets without changing source identity or final comparison disposition.
-- Preserve `Frame` handling for `shellnl-s4-final` as accepted factor-one state identity; do not expose
-  trial Newton history as reference rows.
-- Derive constrained reaction identity from the input mask. Compare `RM1/RM2` with the global
-  spatial physical reaction moment, not the raw generalized rotation-coordinate covector.
-- Preserve approved Gauss direct stress recovery. Do not create element-corner stress,
-  extrapolation, averaging or a stress CSV projection for the current optional SPOS/SNEG artifacts.
-- Keep `RM3`, `S-S33`, `S-S11`, `S-S22` and `S-S12` out of current comparison families.
-- Use the common tolerance policy exactly as written above and in `docs/TOLERANCE.md`.
+I/O Definition Agent handoff through Coordinator:
 
-Reference artifact status: complete for I/O Definition. No declared required input or required
-comparison CSV is missing or unreadable. Optional stress CSVs are present and readable as inventory
-evidence only. No reference artifact was generated, renamed, repaired, normalized, or modified.
+- Fine primary와 coarse companion nonlinear case의 accepted factor-one identity를 보존한다.
+- Post-closure `_02`는 기존 fine case와 독립 case/family로 projection하고 별도 current-code
+  verification에 사용한다.
+- Section 4.4의 `(a)` applied-plus-reaction balance error, `(b)` constrained reaction resultant,
+  `(c)` accepted free residual을 separate logical quantities로 최종 projection한다.
+- Global moment는 origin `[0,0,0]`, current `X+u` force arm과 spatial physical nodal moment를
+  사용한다. General nonzero prescribed translation/rotation에서도 initial arm/raw rotational
+  residual을 재사용하지 않는다.
+- Local RF/RM은 exact source-key/schema/inventory/finite/error reporting이 있는 review-only다.
+  Local rows를 global sum으로 대체하거나 blocking으로 되돌리지 않는다.
+- Approved Gauss direct stress recovery를 유지한다. Optional element-corner stress artifact에
+  맞춘 extrapolation/averaging 또는 stress comparison projection을 만들지 않는다.
+- Common external tolerance와 exact prechecks를 변경하지 않는다.
+
+Reference artifact status: required input/displacement/reaction artifacts are present and readable.
+Optional fine stress identity issue는 transparent nonblocking inventory finding이다. 어떤 reference
+artifact도 생성, rename, repair, normalize 또는 수정하지 않았다.

+
+## 6. Known Limitations
+
+1. Coarse/fine local nodal `RF1/RF2/RF3`와 physical spatial `RM1/RM2`에는 six review-only
+   discrepancy families가 남아 있다. Exact source-key/schema/inventory/finite/error report는 유지하지만
+   blocking verdict는 global force/moment balance와 accepted free residual이 결정한다.
+2. Local `RM3`는 approved physical external comparison target이 없어 excluded다.
+3. Stored corner `SPOS/SNEG` stress와 FESA direct Gauss `BOTTOM/MIDDLE/TOP` stress는 위치·복구 identity가
+   다르므로 numerical comparison에서 제외된다. Fine optional stress CSV에는 element `1`, `SNEG`의
+   malformed `Node Label=ss` 한 행이 있으며 artifact를 repair하지 않는다.
+4. `UR1/UR2/UR3` external comparison은 warning-only다. Current portfolio에서는 모두 통과했지만 향후
+   warning exceedance가 blocking failure로 자동 승격되지는 않는다.
+5. Stored nonlinear plate responses는 weak geometric-nonlinear regime다. Finite-rotation/tangent/objectivity/
+   rollback은 internal invariant tests로 보강했지만 broad large-response benchmark 또는 experimental
+   validation claim은 하지 않는다.
+6. Original-style MITC4는 curved/distorted/thin nonlinear mesh에서 membrane-locking과 conditioning
+   위험이 있다. MITC4+ 또는 Abaqus `S4/S4R` 성능을 상속한다고 주장하지 않는다.
+7. 첫 release는 one-step, materially linear, fixed-increment Full Newton 범위다. Limit-point traversal,
+   material nonlinearity, follower/distributed load, adaptive increment와 broader Abaqus keyword compatibility는
+   지원하지 않고 fail-closed한다.
+8. Rotation-vector principal chart, director/swing/twist branch와 geometry/Jacobian validity 밖의 상태는
+   fail-closed한다. No line search/cutback/retry이므로 difficult path의 automatic recovery를 보장하지 않는다.
+9. Global force/moment `<=1e-8`은 comparator-owned internal verification gate이며 runtime user setting이나
+   `fesa.env` 계약이 아니다. External CSV families에는 별도로 `docs/TOLERANCE.md`만 적용한다.
+10. Numerical agreement은 Abaqus formulation, integration, stabilization, state update 또는 recovery의
+    internal equivalence evidence가 아니다.
+
+## 7. Release Notes Draft
+
+### 기능 요약
+
+FESA에 fixed-initial-reference Total Lagrangian 기반 geometric-nonlinear `FESA-MITC4` static
+procedure가 추가되었다. Solver는 fixed load-factor path에서 Full Newton-Raphson을 수행하고,
+수렴한 increment만 HDF5 schema v1 accepted frame으로 commit한다. Trial/committed finite-rotation state,
+deterministic per-iteration log, rollback-safe output lifecycle, current-arm/spatial-moment global equilibrium
+evidence를 포함한다.
+
+### 사용과 산출물
+
+- 실행: `fesa.exe <model.inp>`
+- 결과: input sibling `<stem>_results.h5`
+- 진단: input sibling `<stem>_log.txt`
+- 지원 핵심 범위: one `*STEP, NLGEOM=YES`, one four-value `*STATIC`, source `S4/S4R`, isotropic
+  linear elastic shell, `*CLOAD`, `*BOUNDARY`의 approved subset.
+- Literal `--output`은 제거되었고 alias/deprecation form 없이 exit `2`로 거부된다.
+
+### 검증 범위
+
+MSVC x64 Debug full CTest `302/302`, nonlinear/extended reference `9/9`, Physics focused `23/23`이
+통과했다. Fine/coarse nonlinear plate와 linear control의 `U1/U2/U3` blocking comparison,
+warning-only UR, accepted free residual 및 normalized global force/moment `<=1e-8`을 검증했다.
+
+### 사용자에게 알려진 제한
+
+Local nodal RF/RM discrepancy는 review-only이며 `RM3`와 stored stress comparison은 제외된다.
+Fine optional stress CSV의 malformed node label은 read-only로 유지한다. UR은 warning-only다.
+Stored nonlinear cases는 weak response이고 original MITC4는 curved/distorted mesh membrane-locking 위험이
+있으므로 broader large-response, locking-free 또는 external-solver internal-equivalence claim을 하지 않는다.
+Material nonlinearity, multiple/mixed steps, follower/distributed loads, line search/cutback/retry,
+arc-length와 broad Abaqus keyword compatibility는 지원 범위 밖이다.
+
+### Evidence artifacts
+
+- `docs/nonlinear-static-newton-raphson/implementation-report.md`
+- `docs/nonlinear-static-newton-raphson/build-test.md`
+- `docs/nonlinear-static-newton-raphson/reference-comparison.md`
+- `docs/nonlinear-static-newton-raphson/physics-evaluation.md`
+- Authoritative solver artifact: each input sibling `<stem>_results.h5`
+
+## 8. Release Verdict
+
+- verdict: `ready-for-release`
+- gate basis: full build/test evidence passed, reference comparison overall status is
+  `pass-for-physics-evaluation`, Physics status is `pass-for-release-agent`, 24/24 must requirements have
+  explicit acceptance/test/reference/release disposition, and no blocking evidence gap remains.
+- qualification: six local RF/RM findings, stress/RM3 exclusions, warning-only UR와 model-coverage limitations are
+  approved and disclosed nonblocking limitations, not unresolved implementation defects.
+- feature identity disposition: `reference-comparison.md`의 literal `feature_id` omission은 exact
+  path/title/hash/handoff binding으로 해소되고 contradictory identity가 없으므로 verdict를 낮추지 않는다.
+- authority boundary: 이 verdict는 internal feature delivery closure recommendation이다. Publish, deploy,
+  package, tag, external release 또는 solver equivalence claim을 승인하지 않는다.
+
+## 9. Handoff Recommendation
+
+Coordinator Agent가 이 보고서의 exact path/hash와 `ready-for-release`를 독립 audit한 뒤 Stage 8을
+`passed`로 기록하고 8-stage workflow를 closure할 것을 권고한다. Evidence gap return 또는 owning
+sub-agent rework는 필요하지 않다. 사용자가 요청한 commit/push는 Coordinator/root가 Release gate
+audit 후 별도로 수행해야 하며, 이 Release Agent는 commit, push, tag 또는 publish를 수행하지 않는다.
+
+## 10. No-Change Assertion
+
+이 Stage 8 작업은 `docs/nonlinear-static-newton-raphson/release.md` 하나만 생성했다. Coordinator가
+동시에 소유한 pre-existing `coordination.md` 변경은 읽기만 했고 수정·revert하지 않았다. Source code,
+headers, tests, CMake, Harness, requirements, research, formulation, numerical review, reference model,
+I/O, implementation/physics reports, reference artifacts와 `docs/TOLERANCE.md`를 변경하지 않았다.
+Abaqus, Nastran 또는 다른 reference solver, build, CTest, Harness, publish/deploy/package/tag 작업을
+실행하지 않았다.
+
+## 11. Open Issues
+
+Blocking open issue는 없다.
+
+| id | severity | disposition |
+| --- | --- | --- |
+| `RELEASE-META-001` | nonblocking documentation | `requirements.md`의 historical draft/pending metadata는 current-hash explicit user approval와 Coordinator Stage 1 pass로 해소된다. Upstream 문서는 이 gate에서 수정하지 않았다. |
+| `RELEASE-META-002` | nonblocking documentation | `reference-comparison.md`에는 literal `feature_id` field가 없지만 exact bundle path/title/SHA-256/Stage 6 handoff와 Physics source hash가 feature identity를 결정적으로 고정한다. Contradictory identity는 없고 upstream report는 변경하지 않았다. |
+| `RELEASE-LOCAL-001` | accepted risk | Six local RF/RM families remain review-only findings; global balance/free residual blocking evidence passed. |
+| `RELEASE-STRESS-001` | accepted limitation | `RM3`와 stored stress numerical comparison은 excluded; fine optional malformed stress row는 read-only로 유지한다. |
+| `RELEASE-COVERAGE-001` | known limitation | Weak nonlinear stored response와 original MITC4 curved/distorted membrane-locking risk가 broader claims를 제한한다. |
+
+Missing required report, failed pass status, unresolved defect, missing declared comparison file 또는
+contradictory acceptance evidence는 발견되지 않았다.

 ## 10. Tolerance Policy
 - `.inp` values remain in the user's consistent unit system; FESA performs no unit inference or conversion.
-- Only nonzero-scale convergence ratios are dimensionless and pass with `<=1e-2`.
-- Exact-zero residual thresholds are `1e-3` force and `1e-3` force-length; correction thresholds are `1e-3` length and `1e-3` dimensionless rotation. Equal literals do not merge their dimensions.
-- External comparisons use `docs/TOLERANCE.md`; internal invariant, tangent, endpoint-arithmetic and physics tolerances are fixed by Numerical Review before implementation.
+- Residual ratios with nonzero matching external-channel scale and correction ratios with nonzero current-trial incremental-solution denominator are dimensionless and pass with `<=1e-2`.
+- Exact-zero matching external-channel residual thresholds are `1e-3` force and `1e-3` force-length; exact-zero correction-denominator thresholds are `1e-3` length and `1e-3` dimensionless rotation. Equal literals do not merge their dimensions.
+- External blocking, warning-only, and review-only error reporting use `docs/TOLERANCE.md` without changing their verdict disposition; internal invariant, tangent, endpoint-arithmetic, free-residual and global-balance tolerances are fixed by Numerical Review before implementation.
 
 ## 11. Reference Case Requirements
-- The current Stage-1 gap is selection of exact stored nonlinear input and only the CSV quantities required for acceptance.
-- Numerical Review owns artifact readiness, blocking/warning families, source/component identity and HDF5 projection; this gap does not require another Stage-1 user question.
+- Stored nonlinear candidates use exact read-only input/displacement pairs `reference/shellNL/shellNL.inp` with `reference/shellNL/shellNL displacements.csv`, and `reference/shellNL-meshfine/shellNL-meshfine.inp` with `reference/shellNL-meshfine/shellNL-meshfine displacements.csv`. Exact local-reaction review artifacts are `reference/shellNL/shellNL reactions.csv` and `reference/shellNL-meshfine/shellNL-meshfine reactions.csv`; they are not missing-required blocking artifacts. The existing linear-limit pair is `reference/shell/shell.inp` and `reference/shell/shell displacements.csv`.
+- Numerical Review shall fix which exact nonlinear candidate case or cases are blocking versus diagnostic, the factor-one HDF5 projection, required source rows/components and comparison families, and the internal tolerances for global balance/free-residual gates. `U1/U2/U3` are blocking, `UR1/UR2/UR3` are warning-only, local nodal RF/RM rows are review-only, and `RM3` and stress have no numerical comparison projection.
+- All selected local review rows retain deterministic identity, schema, finite-value, inventory, and error reporting even though they cannot fail the blocking verdict. A physical global resultant sum is not a substitute identity for those local rows, and no row is averaged, collapsed, omitted, zero-clamped, or repaired.
 - Agents do not run Abaqus, Nastran or another reference solver and do not create, rename, repair or normalize stored reference artifacts.

+- Numerical Review: verify the revised NSNR-069 branch and unchanged thresholds/four-channel AND, endpoint arithmetic, tangent/objectivity/state-invariant checks, benchmark portfolio and performance adequacy. Fix exact coarse/fine reference roles, local review projection/families, and factor-one global balance/free-residual tolerances while preserving local RF/RM review-only, `RM3` exclusion, displacement/rotation disposition, exact prechecks, immutable artifacts and common external tolerance.
+- I/O Definition: HDF5 schema/projection/chunking/factor-0 handling, log representation/failure presentation and path/collision conventions. Audit and keep separately identifiable `(a)` global applied-plus-reaction balance error, `(b)` constrained-reaction resultant and `(c)` accepted free residual; global moments use current positions and spatial physical nodal moments about `[0,0,0]`, including supported nonzero prescribed translation/rotation cases.
+- Implementation Planning: backend adapters, output ownership primitive, candidate filename, performance targets and requirement-traced TDD plan. Stage 6 must test the three equilibrium identities separately and must not reuse one implementation dataset as another without proving its approved projection semantics.

+This focused report recomputes only global translational displacement components
+`U1/U2/U3` for the existing coarse `reference/shellNL` case and the added fine
+`reference/shellNL-meshfine` case.  It is diagnostic evidence for the observed
+mesh sensitivity; it does not create or replace the canonical Stage 6
+`reference-comparison.md`.  In particular, it is not Step 12 implementation
+evidence and does not change any workflow gate.
+
+The two meshes are compared separately to their own read-only Abaqus CSV
+artifacts.  No coarse-to-fine node interpolation, row pairing, averaging, or
+direct FESA-to-FESA error was used.

+
+## 3. Source identity and prechecks
+
+The comparison key is
+
+```text
+(accepted_state=factor-one, canonical_instance_name, source_node_label, component)
+```
+
+`canonical_instance_name` is matched case-insensitively; the CSV/HDF5 source
+spelling itself is not rewritten.  CSV columns were selected after trimming only
+surrounding header whitespace.  The `U-U1/U-U2/U-U3` columns map respectively to
+HDF5 `UX/UY/UZ`.  Row order is not part of the identity and was not used for
+matching.
+
+| mesh | component rows | duplicate CSV wide/component/HDF5 keys | nonfinite CSV/HDF5 values | missing HDF5 keys | extra HDF5 keys | precheck |
+| --- | ---: | --- | --- | ---: | ---: | --- |
+| coarse | 147 | `0 / 0 / 0` | `0 / 0` | 0 | 0 | pass |
+| fine | 2,187 | `0 / 0 / 0` | `0 / 0` | 0 | 0 | pass |
+
+Each CSV contains only the exact factor-one `Frame` value shown above.  Thus the
+row prechecks required before numerical tolerance evaluation pass for the
+translation projection in each mesh.
+
+## 4. Applied tolerance policy
+
+`U1/U2/U3` remain one global-length, blocking translation family within each
+case.  The component rows in Section 6 are diagnostics only: they use the same
+case-family scale and near-zero band below and do not introduce a component
+scale, component-specific tolerance, or a new approved family.
+
+For the reference values `r_i` and FESA values `f_i`, `docs/TOLERANCE.md` is
+applied exactly:
+
+\[
+S=\max_i|r_i|,\qquad B=0.01S,\qquad e_i=|f_i-r_i|.
+\]
+
+- If `|r_i| <= B`, the row passes iff `e_i <= B`.
+- Otherwise, the row passes iff `e_i / |r_i| <= 0.05`.
+- The whole family also requires `RMS(e_i) / S <= 0.01`.
+- There is no independent absolute-error gate, `max(1,S)` floor, zero clamp,
+  row omission, or averaging.  A zero-scale family would require exact FESA
+  zero; neither translation family has zero reference scale.
+
+## 5. Translation-family results
+
+| mesh | rows | `S` | `B=0.01S` | near-zero / significant rows | row failures | max absolute error | max significant-row relative error | RMS error | `L2(error)` | relative RMS | verdict |
+| --- | ---: | ---: | ---: | ---: | ---: | ---: | ---: | ---: | ---: | ---: | --- |
+| coarse | 147 | `2.3740820300000001e-05` | `2.3740820300000003e-07` | 122 / 25 | 0 | `1.9037855439354404e-07` | `8.5711169439298945e-03` | `2.4530813178127803e-08` | `2.9742030342848264e-07` | `1.0332757195473908e-03` | pass |

+
+Both sets have zero row failures and relative RMS values below the common
+`0.01` threshold.  This is a translation-only diagnostic pass; it is not a
+full external-reference verdict for the nonlinear-static feature.
+
+## 6. Component diagnostics under the unchanged family scale
+
+The `near-zero/significant` counts and every row decision below use the Section 5
+family band `B`, not a component-derived scale.  A dash for maximum relative
+error means all rows of that component were near-zero and were therefore judged
+only by the approved absolute-band rule.

+## 8. Mesh trend interpretation
+
+The fine-mesh translation relative RMS divided by the coarse-mesh translation
+relative RMS is
+
+\[
+\frac{2.2723025777921402\times10^{-4}}
+     {1.0332757195473908\times10^{-3}}
+=0.21991251074664606.
+\]
+
+This is a `78.008748925335397%` reduction in the separately measured
+reference-normalized translation RMS.  It is consistent with the hypothesis
+that the coarse-case discrepancy is mesh-sensitive, and the fine case also
+passes the same row/RMS policy.
+
+It is not an observed order of convergence, a proof of monotonic convergence,
+or a solution-accuracy claim outside these translation rows: the two models have
+different meshes and distinct external-reference outputs, and no common-mesh
+interpolation or mesh-size-rate study was performed.
+
+## 9. Explicit exclusions and no-change assertion
+
+This report deliberately excludes:
+
+- all reaction quantities;
+- `UR1/UR2/UR3` rotations;
+- all stress quantities, including the user-noted `reference/shell` element-label
+  ordering change;
+- Newton convergence lifecycle and iteration-log acceptance beyond identifying
+  the accepted factor-one HDF5 frame;
+- `USER-DECISION-004` disposition;
+- Step 11 and Step 12 status, Physics Evaluation, and Release readiness.
+
+No source, test, CMake, comparator, tolerance policy, phase file, canonical
+reference-comparison report, declared input, or reference artifact was modified
+for this report.  The report also does not create `implementation-report.md`,
+`build-test.md`, or `reference-comparison.md`.
+
+## 10. Handoff
+
+Within this narrow scope there is no artifact, identity, finite-value, or
+translation-tolerance blocker.  The report is handed to the Coordinator as
+translation-only diagnostic evidence; gate ownership and all excluded work remain
+unchanged.
