# Nonlinear Static Newton–Raphson Coordination Record

## 1. Metadata and Feature Scope

- feature_id: `nonlinear-static-newton-raphson`
- workflow_state: `needs-implementation`
- owner_agent: `coordinator-agent`
- request_date: `2026-08-18`
- last_updated: `2026-08-24` (REWORK-004 corrected; no-push Harness rerun authorized)
- 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: Stage 6 no-push Harness/Implementation rerun is authorized for Executor-selected Step 0 and subsequent approved phase progression under the corrected `codex exec --disable unified_exec` runner envelope.
- 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. The authorized rerun envelope is Codex CLI `0.149.1`, `CODEX_HOME=C:\Users\baram\.codex`, child launch PATH filtering of `C:\Program Files\WindowsApps\Microsoft.PowerShell_*` and `C:\Users\baram\AppData\Local\Microsoft\WindowsApps`, `workspace-write`, implementation-agent `gpt-5.6-terra`/`xhigh`, hooks retained, no-push, no `danger-full-access`, and runner-retained `--disable unified_exec`. Do not edit feature contracts/reference artifacts/tolerance policies, run Abaqus/Nastran/reference solvers, or advance Physics/Release until `implementation-report.md`, `build-test.md`, `reference-comparison.md` and passing implementation evidence exist.
- repository_audit: 기존 worktree에는 `.codex/agents/*.toml`과 `AGENTS.md`의 사용자 변경이 있으며 이를 보존한다.

## 3. Active Dispatch Package and Latest Sub-Agent Return

### Active Dispatch Package

- feature_id: `nonlinear-static-newton-raphson`
- current_dispatch: `stage-6-no-push-harness-implementation-rerun`
- target_sub_agent: `implementation-agent` via Harness Executor (`python scripts/execute.py nonlinear-static-newton-raphson`; root launch required)
- required_inputs:
  - User explicit execution request on `2026-08-24`: `Harness/Implementation를 실행해주세요.`
  - Attempt 1 failure evidence: no-push Harness command `python scripts/execute.py nonlinear-static-newton-raphson`; `codex exec --json --sandbox workspace-write ...` timed out at `1800.7s`; `_invoke_codex` raised uncaught `subprocess.TimeoutExpired`; no Step 0 source/test edits, no `step0-output.json`, no `MAX_RETRIES` handling.
  - Bounded Harness repair evidence: Implementation Agent changed only `scripts/execute.py` and `tests/test_execute.py`; TDD RED 3 expected failures, GREEN 3 passed; focused `tests/test_execute.py` 10/10 passed; full pytest 23 passed/1 pre-existing HEAD contract failure `xhigh` actual vs `extra high` expected.
  - Repair behavior now required: Codex timeout returns structured exit `124` and reaches `MAX_RETRIES`; runner reads `.codex/agents/implementation-agent.toml` and passes `gpt-5.6-terra` plus `xhigh` settings to `codex exec`.
  - Root independent review evidence: no new defect found; focused `tests/test_execute.py` 10/10 reproduced; full suite reproduced the same single pre-existing `xhigh` vs `extra high` mismatch.
  - Attempt 2 failure evidence: repaired Executor wrote `phases/nonlinear-static-newton-raphson/step0-output.json` with `exitCode` 124 and stderr `Codex timed out after 1800 seconds.`; stdout shows the Implementation Agent completed a turn but every nested command execution remained `status=in_progress`.
  - Runtime blocker evidence: nested commands hung for skill file reads, `Get-Date`, `cmd.exe /d /c echo test`, and `exit 0`; root classifies the cause as nested Codex Windows shell tool execution hang, not model delay, build, source, sandbox/auth, or the repaired Executor timeout/no-retry path.
  - Active process evidence from root: Executor auto-started another internal retry at `2026-08-24T02:58:35+09:00` under `python execute.py` PID 13820 / `codex` PID 7704; root terminated those unauthorized retry PIDs and verified none remain.
  - Root decision after blocked-no-auto-retry: authorize one bounded Correction Agent diagnostic/rework cycle because the repeated implementation failure is infrastructure/runtime, not physics/source/build.
  - Correction Agent return: status `blocked`, output `docs/nonlinear-static-newton-raphson/corrections.md` SHA-256 `C9F93AC99225725C88BB7F0BABC8F7D75D3E05082070090328203DB3776BEFE6`, no runner/test edits from correction, no safe documented CLI flag workaround proven.
  - User/root runtime update evidence: standalone Codex CLI updated `0.147.0 -> 0.149.1` under `CODEX_HOME=C:\Users\baram\.codex`; `codex doctor --json` reported current/consistent installation.
  - User/root bounded smoke evidence: baseline still fails through inaccessible WindowsApps `pwsh`, direct `codex sandbox` elevated/unelevated `cmd echo` exits 0, and nested smoke passes only when launch env filters `C:\Program Files\WindowsApps\Microsoft.PowerShell_*` plus `C:\Users\baram\AppData\Local\Microsoft\WindowsApps`, aligns `CODEX_HOME`, retains `workspace-write` and hooks, uses implementation-agent `gpt-5.6-terra`/`xhigh`, and passes `--disable unified_exec`; output was exactly `CODEX_SHELL_SMOKE_OK\r\n`.
  - REWORK-004 Correction Agent return: status `corrected-for-implementation-rerun`; changed only `scripts/execute.py`, `tests/test_execute.py`, `docs/nonlinear-static-newton-raphson/corrections.md`; no Harness phase, C++ source, CMake, reference solver, commit or push.
  - Coordinator audit: current `scripts/execute.py` lines 300-315 pass exact adjacent args `--disable`, `unified_exec` immediately after `codex exec`; current test `test_invoke_codex_uses_implementation_agent_command_contract` asserts the pair while preserving `gpt-5.6-terra` and `model_reasoning_effort="xhigh"`.
  - `AGENTS.md`, `docs/SOLVER_AGENT_DESIGN.md`, `docs/HARNESS.md`, `docs/HARNESS_WORKFLOW.md`, `.agents/skills/harness/SKILL.md`, `.codex/hooks.json`
  - `docs/nonlinear-static-newton-raphson/implementation-plan.md` SHA-256 `BF4FC7A5CFDEEC19D62A36E1DF7CC34C0B9F614FA0A0FD8D0A321ADC73E69580`
  - `phases/index.json` SHA-256 `F8BE89D579C303410BD1D2CD17AF33FCAD72BF68D9E10C3F644A39D1AA7331FB`
  - `phases/nonlinear-static-newton-raphson/index.json` SHA-256 `439B67E1DED442D828EB5C31DAB35D28F32DBA6F66537512CAFFB5616956C137`
  - Executor-selected initial current Step: `phases/nonlinear-static-newton-raphson/step0.md`, Step 0 `cli-output-lease-and-derived-names`, status `pending`
  - Approved Stage 1-5 hashes: requirements `910E351F3F90FFA42F07D15206B55E62C05EAE821E250424430148337506EBF2`; research `C920A6B02381230D1DB419D73FE767D611B36720D27D6410507BA88C3CA28EEE`; formulation `DFA629888041D5762FD0DF4271353464A692B325DC0C821A8D8689688C1EAFD0`; numerical-review `9517E11804C45A6F3822D18821D52EA493AE20353C8FFAD61E960F4315977D01`; reference-model `52D10B1D0C0500B295C5E48BCB3618B309D9696371B8070D4E3DCEE8D3D74CD3`; io `DBB959A68F17D67CA2B42569610B9C1B595A8BFB5502BC194B7E62B656031B28`.
  - Preserved materialization evidence: exactly one pending phase entry, 13/13 pending steps, Step 0 remains pending, no implementation evidence docs yet.
- expected_outputs:
  - Executor-managed no-push phase execution from Step 0, with branch/pending selection/retry/timestamps/commits/advancement owned only by `scripts/execute.py`.
  - Each Implementation Agent session performs only its Executor-selected current Step `RED -> observed failure -> minimal GREEN -> VERIFY`, updates only that Step status payload, and stops.
  - Final Stage 6 evidence remains `docs/nonlinear-static-newton-raphson/implementation-report.md`, `docs/nonlinear-static-newton-raphson/build-test.md`, and `docs/nonlinear-static-newton-raphson/reference-comparison.md` after the approved phase reaches its final verification Step.
- acceptance_gate: Root is explicitly authorized to run no-push `python scripts/execute.py nonlinear-static-newton-raphson` in the isolated worktree using Codex `0.149.1`, `CODEX_HOME=C:\Users\baram\.codex`, a child PATH filtered of `C:\Program Files\WindowsApps\Microsoft.PowerShell_*` and `C:\Users\baram\AppData\Local\Microsoft\WindowsApps`, `workspace-write`, hooks retained, implementation-agent `gpt-5.6-terra`/`xhigh`, and no `danger-full-access`. Passing Stage 6 still requires successful Implementation phase execution plus Coordinator audit of `implementation-report.md`, `build-test.md`, `reference-comparison.md`, full MSVC x64 Debug build/CTest, blocking reference comparison and no forbidden reference/upstream/tolerance mutation.
- stop_condition: If nested shell execution hangs or cannot complete under the exact corrected runner and approved launch envelope, stop as `blocked` with the new evidence; do not broaden to `danger-full-access`, do not run Abaqus/Nastran/reference solvers, do not generate/modify reference CSVs, and do not advance Physics/Release.
- missing_evidence: No-push Harness rerun result and Stage 6 implementation evidence docs remain absent.

### Latest Sub-Agent Return

- target_sub_agent: `correction-agent`
- output_paths:
  - `docs/nonlinear-static-newton-raphson/corrections.md`
- status: `corrected-for-implementation-rerun` (owner); Coordinator decision `passed-for-implementation-rerun`
- evidence_summary:
  - `corrections.md` SHA-256 is `82572437689B41323B6533C2361F2F12BF07B5ED305825AA84C56AEEDC729930`.
  - `scripts/execute.py` SHA-256 is `E36A78E5C0AE7E91361B1AB6B995D2E8CF51569C0E0804D57F54711AFEFFB806`; `tests/test_execute.py` SHA-256 is `1E368382ABA21F5FBAC344E15E1E600B6BDAF4C4528431E4D1A757AA09D54CDE`.
  - Runner command contract now starts `codex exec --disable unified_exec --json ...` and still passes `--model gpt-5.6-terra`, `--config model_reasoning_effort="xhigh"`, `--sandbox workspace-write`, `--dangerously-bypass-hook-trust`, `--cd <repo>`.
  - TDD evidence: targeted RED failed on missing adjacent pair with exit 1; targeted GREEN passed; focused `tests/test_execute.py` 10/10; full pytest remains 23 passed/1 pre-existing `xhigh` vs `extra high`; MSVC Debug build exit 0; CTest discovery 214; full CTest 214/214.
  - Correction did not run Harness phase, edit C++/CMake/reference artifacts, run reference solvers, commit or push.
- blockers:
  - 없음 for runner-option correction; Stage 6 implementation evidence is still pending.
- self_audit_findings: Coordinator verified the correction report hash, audited current runner args and regression assertion, checked phase index pending statuses, did not run phase/build/tests/reference solvers, and updated only this isolated worktree `coordination.md`.
- return_contract_check: output path, corrected status, evidence summary, blockers and changed-file assertion are present.
- acceptance_evidence_check: REWORK-004 is closed; Stage 6 is eligible for no-push Harness rerun, but no implementation pass evidence exists yet.

Coordinator/root audit passed phase uniqueness, 13/13 pending steps without executor metadata, 151 root assertions, reference hashes/row counts and no unauthorized evidence docs/execution/source/test/CMake/reference edits. | `ready-for-implementation` | Await separate explicit Harness/implementation execution request; do not run Executor automatically |
| 2026-08-24 | Harness/Implementation execution authorization and dispatch package | `in-progress` | User explicitly requested Harness/Implementation execution. Coordinator verified materialized phase still has Step 0 `cli-output-lease-and-derived-names` as the first pending Step, preserved Stage 1-5 hashes and materialization evidence, and prepared no-push `scripts/execute.py nonlinear-static-newton-raphson` dispatch. | `needs-implementation` | Run no-push Harness executor; await Implementation/Harness return before any physics/release transition |
| 2026-08-24 | Harness/Implementation execution attempt 1 | `needs-rework` | No-push Harness attempt failed before Step 0 evidence: `codex exec --json --sandbox workspace-write ...` timed out at `1800.7s`; `_invoke_codex` raised uncaught `subprocess.TimeoutExpired`; no source/test edits, `step0-output.json`, `MAX_RETRIES`, or Step evidence. Normalized classification `harness-uncaught-step-codex-timeout-no-retry` attempt 1. | `needs-implementation` | Bounded Harness repair before retry; do not route to Correction Agent for first clear harness failure |
| 2026-08-24 | Harness repair after attempt 1 | `passed` | Implementation Agent repaired Harness timeout/profile handling in `scripts/execute.py` with tests in `tests/test_execute.py`; RED 3 expected failures, GREEN 3 passed, focused 10/10 passed, full pytest 23 passed/1 pre-existing `xhigh` vs `extra high` mismatch. Root review found no new defect and reproduced the same evidence. No phase execution, phase/source/CMake/reference/evidence docs edit, or reference solver activity. | `needs-implementation` | Retry no-push Harness attempt 2 for Executor-selected Step 0 in workspace-write; if the same normalized timeout recurs, stop automatic rework and route to `needs-user-decision` or `blocked` |
| 2026-08-24 | Harness/Implementation execution attempt 2 | `blocked` | Repaired Executor produced `step0-output.json` with `exitCode` 124 and stderr `Codex timed out after 1800 seconds.`. The Implementation Agent turn completed, but every nested shell `command_execution` remained `status=in_progress` even for `Get-Date`, `cmd echo`, and `exit 0`; Step 0 stayed pending with no production/test changes. Root cause is `harness-nested-codex-windows-shell-tool-execution-hang` attempt 2. | `blocked` | Stop remaining automatic retries; no workaround/further Harness execution until explicit user/root decision or external runtime fix |
| 2026-08-24 | Root correction-cycle authorization | `in-progress` | Root authorized one bounded Correction Agent diagnostic/rework cycle for the repeated infrastructure/runtime failure; unauthorized retry PIDs have been terminated and none remain. Coordinator prepared a correction package limited to no-op/tool smoke reproduction, local Codex CLI/config option inspection, documented flag hypothesis testing, and optional TDD runner changes in `scripts/execute.py`/`tests/test_execute.py`. | `needs-correction` | Root profile dispatch to `correction-agent` is required because this Coordinator runtime exposes no callable `spawn_agent` tool |
| 2026-08-24 | Correction Agent return and Coordinator audit | `blocked` | Correction Agent returned `blocked` and created only `docs/nonlinear-static-newton-raphson/corrections.md` SHA-256 `C9F93AC99225725C88BB7F0BABC8F7D75D3E05082070090328203DB3776BEFE6`. Baseline smoke reproduced no nested shell completion; `--disable code_mode_host` failed closed; `--enable unified_exec` hung; combined flags failed closed. Root verified no nonlinear Harness/Codex processes remain, all 13 steps pending, Python 23 passed/1 pre-existing failure, MSVC build exit 0, discovery 214 and CTest 214/214. | `blocked` | No further Harness retry until external Codex runtime update/repair plus bounded shell smoke success |

## 5. Risk, Blocker, and User-Decision Register

| id | type | description | owner | status |
| --- | --- | --- | --- | --- |
| BLOCKER-001 | dispatch | Stage 4 requires a valid `numerical-review-agent` child dispatch. Root supplied the valid profile dispatch and owner return, so this runtime-tooling blocker no longer blocks the gate. | `coordinator-agent` / runtime tooling | closed |
| REWORK-001 | report-contract | Stage 4 returned evidence had a cross-report contradiction on stress CSV and `RM3` comparison disposition. Corrected reports now consistently treat stress CSVs as optional read-only inspection/order evidence only and exclude `RM3` from comparison. | `numerical-review-agent` | closed |
| REWORK-002 | io-contract | Stage 5 `io.md` bounded correction completed: public CLI `--output` substring rejection, Newton iteration log schema, exact `VARIABLE=PRESELECT` ignored-with-warning handling, repository-wide non-Newton log lifecycle, DECISION-028/029/030 path/log lifecycle and collision semantics are now recorded in `io.md`. | `io-definition-agent` | closed |
| REWORK-003 | harness | Stage 6 attempt 1 timeout/no-retry defect is repaired in Harness infrastructure: timeouts now return structured exit `124` through `MAX_RETRIES`, and implementation-agent profile settings are passed to Codex. Same normalized failure attempt count remains 1; attempt 2 is authorized and same-class recurrence stops automatic rework. | `implementation-agent` via Harness Executor | closed |
| BLOCKER-002 | harness-runtime | Nested Codex Windows shell tool execution hung inside Implementation/Correction Codex sessions. It is mitigated for the authorized rerun by Codex CLI `0.149.1`, aligned `CODEX_HOME`, filtered WindowsApps PATH entries, smoke success with exact `CODEX_SHELL_SMOKE_OK` output, and REWORK-004 runner retention of `--disable unified_exec`. Reopen only if the same hang recurs under the exact approved envelope. | external Codex runtime / user-root decision | mitigated |
| BLOCKER-003 | dispatch-runtime | This Coordinator runtime exposed no callable `spawn_agent` tool, but root successfully performed the required Correction Agent profile dispatch. | coordinator/root tooling | closed |
| REWORK-004 | harness | Corrected: `scripts/execute.py` now passes adjacent `--disable`, `unified_exec` immediately after `codex exec`; `tests/test_execute.py` asserts this while preserving terra/xhigh routing; `corrections.md` records RED/GREEN/VERIFY and no Harness phase/source C++/CMake/reference edits. | `correction-agent` | closed |
| RISK-001 | architecture | 기존 `LinearStaticAnalysis` private lifecycle은 단일 factorization/substitution과 final frame만 소유하므로 nonlinear increment/iteration/state commit을 삽입하면 ADR 경계를 위반한다. | `coordinator-agent` routing | open |
| RISK-002 | scope | `Newton–Raphson`은 solution algorithm이고 geometric/material/contact nonlinearity 범위를 단독으로 결정하지 않는다. | `requirement-agent` | mitigated by DECISION-001 |
| RISK-003 | contract | 현재 `Element`는 displacement-dependent residual/consistent tangent/trial state 계약이 없고 `AnalysisState`는 nonlinear history를 소유하지 않는다. | downstream formulation/architecture gates | open |
| RISK-004 | input | 현재 `NLGEOM=YES`는 `unsupported-nonlinear-geometry`로 거부되고 `*STATIC` 네 값은 provenance로만 보존된다. | downstream requirements/I/O gates | open |
| RISK-005 | verification | exact nonlinear reference artifacts와 path-dependent blocking quantities가 아직 지정되지 않았다. | downstream numerical-review gate | open |
| DECISION-001 | user decision | 첫 release는 materially linear + geometrically nonlinear MITC4로 고정한다. Material-only와 combined material/geometric nonlinearity는 이 release 범위 밖이다. | user via Coordinator | closed |
| DECISION-002 | user decision | First-release geometric-nonlinear MITC4 kinematic framework는 initial configuration 기준 `Total Lagrangian`으로 고정한다. Updated Lagrangian과 corotational 의미는 이 release 범위 밖이다. | user via Coordinator | closed |
| DECISION-003 | user decision | Newton variant는 `Full Newton–Raphson`으로 고정한다. 매 iteration의 current trial/candidate state에서 residual과 algorithmically consistent tangent를 재평가하고, 그 tangent로 새 factorization/solve를 수행한다. Modified Newton과 adaptive refresh는 out-of-scope다. | user via Coordinator | closed |
| DECISION-004 | user decision | First-release nonlinear increment control은 하나의 scalar load coordinate/load factor로 approved load/BC path를 진행하는 `Load-factor control`로 고정한다. Controlled-displacement와 arc-length/path-following control은 out-of-scope다. | user via Coordinator | closed |
| DECISION-005 | user decision | 모든 approved `*CLOAD`와 nonzero prescribed `*BOUNDARY` target은 같은 dimensionless scalar load factor로 step-start 값에서 target까지 비례 진행한다. Fixed step-start BC와 independent/non-proportional amplitude/path는 out-of-scope다. | user via Coordinator | closed |
| DECISION-006 | user decision | First-release는 approved fixed load-factor increment size를 반복하고 factor 1에 정확히 도달하도록 마지막 increment만 작게 조정하는 `Fixed-size stepping`으로 고정한다. Automatic growth, cutback/retry와 explicit schedule은 out-of-scope며 attempted increment failure는 재시도 없이 analysis failure다. | user via Coordinator | closed |
| DECISION-007 | user decision | Nonlinear four-value `*STATIC`은 first positive value만 fixed load-factor increment로 사용하고 second/period는 exact supported endpoint `1`을 요구하며 positive minimum/maximum은 입력 호환성을 위해 수용하지만 runtime stepping에는 사용하지 않는 `First-value driven` mapping으로 고정한다. Strict tuple과 single-value form은 out-of-scope다. | user via Coordinator | closed |
| DECISION-008 | user decision | First-release approved `*CLOAD` force/moment component directions는 initial/current deformation과 무관하게 fixed global frame에 유지되고 common scalar factor로 magnitude만 비례 진행하는 dead-load semantics로 고정한다. Follower nodal loads, selectable dual semantics, external-load geometric tangent/follower work는 out-of-scope다. | user via Coordinator | closed |
| DECISION-009 | user decision | Nonzero prescribed `*BOUNDARY` input value는 factor 1의 absolute global-DOF `Total step target`이며 step-start committed value에서 target까지 common scalar factor로 보간한다. Incremental delta와 selectable dual semantics는 out-of-scope다. | user via Coordinator | closed |
| DECISION-010 | user decision | First release는 입력당 exactly one supported geometrically nonlinear static step만 허용하고 no-prior-history baseline에서 factor 0→1을 수행한다. Multiple nonlinear steps, mixed linear/nonlinear steps, cross-step state/load/BC propagation과 procedure transition은 out-of-scope/fail-closed다. | user via Coordinator | closed |
| DECISION-011 | user decision | First-release increment acceptance는 free-DOF equilibrium residual과 Newton correction의 두 mandatory quantity가 각각 승인 gate를 모두 통과해야 한다. Energy convergence는 diagnostic/mandatory가 아닌 out-of-scope다. Norm, normalization과 tolerance는 별도 결정으로 남긴다. | user via Coordinator | closed |
| DECISION-012 | user decision | Four channel-separated infinity gates의 nonzero-scale relative threshold는 각각 `1e-2`다. Zero denominator에는 own-channel absolute fallback을 적용하며 네 numeric literal은 모두 `1e-3`: force residual은 model-consistent force, moment residual은 force·length, translational correction은 length, rotational correction은 later-approved convention의 dimensionless rotation parameter다. `.inp` 단위 추론/변환은 하지 않는다. | user via Coordinator | closed |
| DECISION-013 | user decision | First release는 `No line search`다. 각 successful fresh tangent correction solve의 full correction을 damping/backtracking/trial-step reduction 없이 next candidate에 그대로 적용하며 merit/acceptance/reduction loop, selectable input과 fallback은 out-of-scope/fail-closed다. | user via Coordinator | closed |
| DECISION-014 | user decision | Attempted increment당 maximum Newton iteration count는 product-fixed `100`이다. Entered iteration은 `1..100`; iteration 100 gate pass는 accept 가능하고 fail 시 iteration 101/candidate/retry/cutback 없이 immediate failure 및 prior committed state/result preservation을 적용한다. | user via Coordinator | closed |
| DECISION-015 | user decision | MITC4 Newton solve는 dimensionless incremental rotation-vector correction을 만들고 authoritative rotational state는 orthonormal right-handed committed triad `Q`이며 director는 third axis다. Separate trial triad를 사용하고 large rotation은 multiplicative composition으로 갱신한다. Exact map/side/frame/parameterization/re-orthonormalization/drilling/derivatives는 downstream gap이다. | user via Coordinator | closed |
| DECISION-016 | user decision | Successful analysis의 authoritative `results.h5`는 each committed nonlinear increment마다 exactly one accepted frame을 stable accepted-factor order로 저장하고 factor-1 frame을 포함한다. Trial/failed/duplicate/missing/partial-final history는 없으며 pre-existing valid final을 exact 보존한다. Exact schema와 factor-0 frame 여부는 downstream gap이다. | user via Coordinator | closed |
| DECISION-017 | user decision | Every entered Newton iteration은 exactly one deterministic structured runtime summary를 낸다. Complete gate는 four-channel identities/norms/branch/threshold/pass/combined transition을 포함하고 early failure는 last-completed/failing stage와 later fields absent/not-evaluated를 기록한다. 이는 diagnostic-only이며 HDF5/sidecar/authoritative/reference quantity가 아니다. Transport/exit mapping은 별도 미결정이다. | user via Coordinator | closed |
| DECISION-018 | superseded user decision | JSON Lines serialization family 결정은 DECISION-023 scope reversal로 current contract에서 retire되며 historical evidence로만 남는다. | user via Coordinator | closed |
| DECISION-019 | superseded user decision | JSON stderr exactly-once emit/flush lifecycle 결정은 DECISION-023 scope reversal로 current contract에서 retire되며 historical evidence로만 남는다. | user via Coordinator | closed |
| DECISION-020 | superseded user decision | JSON field-omission/not-evaluated-list 결정은 DECISION-023 scope reversal로 current contract에서 retire되며 historical evidence로만 남는다. | user via Coordinator | closed |
| DECISION-021 | user operating policy | 물리 결과·수치 거동·public compatibility에 실질 영향 없는 serialization notation/key ordering/diagnostic formatting 등 low-risk 기본 결정은 recommended option을 자동 적용한다. Formulation/Newton/state/tolerance/load-BC/input/failure-rollback/HDF5 authoritative/public compatibility/reference acceptance는 계속 한 번에 하나씩 인터뷰한다. | user via Coordinator | closed |
| DECISION-022 | retired pending decision | JSON stderr write/flush failure policy는 DECISION-023 scope reversal로 선택 없이 retire되었다. | user via Coordinator | closed |
| DECISION-023 | user scope reversal | JSON-specific runtime log decisions와 파생 contracts를 철회하고 serialization-independent OQ-011 granularity를 보존한 simple plain-text analysis log로 재설계한다. Destination은 stderr text 대 actual `.txt` file의 substantive user decision으로 남긴다. | user via Coordinator | closed |
| DECISION-024 | user decision | Solver directly creates exactly one separate plain-text analysis-log file. Per-iteration summaries are file-only; stderr contains log open/write/close fatal diagnostic and final analysis failure summary only, with exact zero per-iteration duplication. External redirect and file+stderr duplication are excluded. Filename/location, overwrite and failure atomicity remain separate questions. | user via Coordinator | closed |
| DECISION-025 | user decision | Repository-wide architectural direction approved: all existing/future analyses use input-directory `<filename>.inp -> <filename>_results.h5` and `<filename>_log.txt`, and `--output` is removed. This requires later approved sectioned-design changes to ARCHITECTURE/ADR and cross-procedure regression evidence; no implementation/global-doc change is claimed now. | user via Coordinator | closed |
| DECISION-026 | user decision | Every invocation containing `--output`, including the formerly valid explicit path form, fails before input parsing/Analysis construction/result-log creation with exact exit 2 and one ordered `cli-usage` stderr diagnostic. No compatibility alias or deprecation window. | user via Coordinator | closed |
| DECISION-027 | user decision | Independent asymmetric lifecycle: current-run log replaces/truncates old log at invocation start and persists on success/failure; HDF5 uses sibling candidate and replaces final only after success, preserving prior valid final on failure; no cross-file pair atomicity. | user via Coordinator | closed |
| DECISION-028 | user decision | Log-I/O grouped fail-closed policy: pre-analysis abort on create/open/truncate failure; immediate abort on write/flush; close failure blocks result commit; best-effort one fatal stderr diagnostic attempt, prior HDF5 and retained log prefix preservation, no retry/fallback/continue/result commit. | user via Coordinator | closed |
| DECISION-029 | coordinator auto-default | OQ-034 low-risk plain-text representation/ordering: UTF-8 no BOM, one physical tab-separated `label=value` line per entered iteration, fixed semantic field/channel order, explicit `not-evaluated(reason)`, locale-independent finite round-trip numerics, embedded control/backslash escaping. No physics/numerics/path/state/authority change. | Coordinator under DECISION-021 | closed |
| DECISION-030 | user decision | OQ-039 user-addressed lexical identity: resolve relative input against invocation CWD, lexically normalize `.`/`..`, do not resolve symlink/junction targets, accept final `.inp` case-insensitively, remove only the last extension and preserve preceding dots/basename case; output beside normalized user-addressed path. | user via Coordinator | closed |
| DECISION-031 | superseded proposal | Same-derived-output concurrent invocation ownership의 fine-grained OQ-040 interview는 사용자 process correction으로 중단했다. 승인된 정책은 없으며 필요한 convention은 I/O/Planning owner가 repository evidence로 정한다. | user via Coordinator | closed |
| DECISION-032 | user process decision | `requirements.md`를 핵심 Stage-1 계약으로 압축하고 OQ chronology, diagnostic/path/concurrency trivia와 반복 handoff를 제거한다. Minor details는 downstream specialist convention/evidence로 정하며 approved scope/physics/tolerance/public compatibility를 바꿀 때만 사용자 결정을 다시 요청한다. | user via Coordinator | closed |
| DECISION-033 | design approval | Target 363 lines, 24 canonical requirements와 24-row Matrix, approved semantic-loss 0의 compact rewrite design. | user via Coordinator | closed |
| DECISION-034 | user process decision | Requirement Agent는 approved physics/scope/tolerance/authoritative-output/public compatibility를 바꾸는 essential decision만 사용자에게 묻고, specialist detail은 owning downstream stage가 repository evidence와 conventional FEM practice로 정한다. Equivalence claim은 금지한다. | user via Coordinator; `.codex/agents/requirement-agent.toml` | closed |
| DECISION-035 | user approval | User explicitly approved Stage 5 `docs/nonlinear-static-newton-raphson/io.md` SHA-256 `DBB959A68F17D67CA2B42569610B9C1B595A8BFB5502BC194B7E62B656031B28` and requested Implementation Planning. | user via Coordinator | closed |

## 6. Rework-Loop Control and Stop Condition

- normalized_failure_attempts: `requirements-next-question-routing-mismatch`: 1; `requirements-output-failure-atomicity-scope-ambiguity`: 1; `requirements-compact-public-contract-omission`: 1; `formulation-equilibrium-reaction-symbol-collision`: 1; `formulation-moment-admissibility-work-inconsistency`: 1; `numerical-review-cross-report-disposition-contradiction`: 1; `io-contract-public-cli-log-output-request-gap`: 1; `harness-nested-codex-windows-shell-tool-execution-hang`: 2
- automatic_rework_limit: 동일 normalized failure classification `2`회
- correction_agent_policy: 명확한 implementation failure는 먼저 `implementation-agent`에 반환하고, 반복되거나 원인이 불명확할 때만 `correction-agent`를 dispatch한다.
- stop_condition: 동일 classification이 두 번이면 자동 rework를 중단하고 workflow를 `needs-user-decision` 또는 `blocked`로 전환한다.
- correction_cycle_authorization: Root-authorized REWORK-004 correction returned `corrected-for-implementation-rerun`; no further correction is active. If the same nested shell hang recurs under the exact corrected runner and approved launch envelope, stop as `blocked` rather than broadening privileges.

## 7. Final Workflow Closure

- closure_status: `not-eligible`
- required_evidence: `docs/nonlinear-static-newton-raphson/release.md`의 `ready-for-release` recommendation
- closure_record: 없음

## 8. No-Change Assertion

- source_code: production solver source 변경 없음; earlier Harness repair and REWORK-004 owners modified only `scripts/execute.py` within runner scope.
- tests: production C++ tests 변경 없음; earlier Harness repair and REWORK-004 owners modified only `tests/test_execute.py` within Harness Python test scope.
- CMake: 변경 없음
- reference_artifacts: 생성·수정·rename 없음
- tolerance_policies: 변경 없음
- phase_files: user-approved planning owner가 `phases/index.json` pending entry와 `phases/nonlinear-static-newton-raphson/index.json`, `step0.md`..`step12.md`를 materialize함; Executor attempt 2 generated `phases/nonlinear-static-newton-raphson/step0-output.json`; Step 0 remains pending and Coordinator did not edit phase files.
- Harness: Implementation Agent bounded repair와 REWORK-004는 `scripts/execute.py`와 `tests/test_execute.py`에 한정됨; REWORK-004 did not run nonlinear Harness phase, commit or push. Coordinator did not run Harness/phase/build/test; root no-push rerun is now authorized under the approved corrected envelope.
- feature_documents: 이번 coordinator update에서는 isolated worktree의 `coordination.md`만 갱신함; Correction Agent가 `docs/nonlinear-static-newton-raphson/corrections.md`를 갱신했고 `implementation-report.md`, `build-test.md`, `reference-comparison.md`는 아직 생성되지 않음
