Execution-prep evidence

• Feature ID: mitc4-shell-feast-eigen
• Owner: implementation-agent
• Input contract revision: r2
• Step: mitc4-shell-feast-eigen-execution-prep / 0 bounded-execution-deadlines
• Outcome: retry — Full VERIFY CTest failed once outside the assigned implementation paths; Coordinator classification is required.

RED

uv run --with pytest python -B -m pytest -v -rs tests/test_harness_timeouts.py returned exit code 1 twice. The first run exposed one test-double setup issue; after that test-only correction, the second run failed 4/4 on the intended pre-change defaults: Executor 1800, Stop shared deadline 1800, CommandSpec 1800, and registered Stop 1800.

Applied scope and partial GREEN

The following owned runtime defaults now match the approved finite limits:

• scripts/execute.py: StepExecutor.CODEX_TIMEOUT_SECONDS = 14400
• scripts/hooks/stop_validation.py: TOTAL_TIMEOUT_SECONDS = 7200
• scripts/msvc_harness/models.py: CommandSpec.timeout_seconds = 7200
• scripts/msvc_harness/process.py: execute_plan(... total_timeout_seconds=7200)
• docs/HARNESS_WORKFLOW.md: shared 7200-second deadline and 7500-second registered Stop explanation

The next focused command returned exit code 1: 2 passed, 2 failed. The executor and shared-deadline/process tests passed. The remaining hook contract test fails because .codex/hooks.json still contains registered Stop timeout 1800.

Blocker and unexecuted verification

The assigned apply_patch edit for .codex/hooks.json was rejected twice by the workspace sandbox as outside the writable project scope. The file is therefore unchanged; no alternate write mechanism was used. This is an environment failure, not a tolerance, contract, or implementation reinterpretation.

Focused verification cannot reach exit 0 until the approved 1800 -> 7500 hook edit is writable. Consequently the prescribed CMake configure/build/CTest and full pytest verification were not run. No reference comparison is applicable to this operational Step. The source currently loads an Executor wrapper deadline of 14400, but this session's actual registered Stop/Codex exit remains unobserved and the registered config still declares 1800.

git diff --check completed with exit code 0. A later read-only JSON status check through uv run python -B -c ... could not initialize the user uv cache because access to C:\Users\baram\AppData\Local\uv\cache\sdists-v9\.git was denied; it did not modify the Step status and is additional environment evidence rather than a replacement for the required verification.

Handoff

Required environment action: make the owned repository file .codex/hooks.json writable to this Step, then apply only its registered Stop timeout change to 7500 and rerun Focused VERIFY followed by Full VERIFY. Existing started_at is preserved; no attempt_history, timestamp, branch, commit, upstream contract, or reference artifact was changed.

재개 실행 결과 (authoritative)

이 절은 위 attempt 1의 historical record를 대체하는 현재 Step 0 실행 결과다. Feature/owner/revision은 mitc4-shell-feast-eigen / implementation-agent / r2이며, 요구 trace는 FEM-REQ-MITC4-EIGEN-023/025, MFE-C27, IO-T11이다.

RED → GREEN

• 최초 uv run --with pytest python -B -m pytest -v -rs tests/test_harness_timeouts.py는 exit 1이었다. 등록 Stop 1800 대 7500의 intended RED와, 상속된 FEM_HARNESS_CODEX_SANDBOX=danger-full-access 때문에 발생한 test-double setup failure를 구분했다.
• workspace-write와 짧은 새 --basetemp를 사용한 direct venv 재현은 exit 1, 3 passed, 1 failed였다. 유일한 failure는 stop["timeout"] == 7500에 대한 실제 1800 값으로, 승인된 intended RED다.
• 최소 GREEN은 .codex/hooks.json의 Stop timeout만 1800에서 7500으로 변경했다. 이전 Correction의 scripts/execute.py classifier 변경과 tests/test_execute.py는 재변경하지 않았다.
• 같은 timeout test는 exit 0, 4 passed였다. 새로운 short workspace --basetemp로 Focused VERIFY를 재실행해 exit 0, 136 passed, 45.05 s를 확인했다. classifier inventory는 test_environment_classifier_ignores_successful_source_echo 6 cases, test_environment_classifier_retains_runtime_helper_failure 16 cases, test_successful_source_echo_preserves_terminal_and_retry 15 cases로 통과했다.

Full VERIFY와 terminal failure

Command	Exit	Result
cmake -S . -B .harness/build -A x64	0	MSVC x64 cache configure, 3.79 s
cmake --build .harness/build --config Debug	0	Debug build, 5.88 s
ctest --test-dir .harness/build -C Debug --show-only=json-v1	0	362 tests discovered, 2.14 s
ctest --test-dir .harness/build -C Debug --output-on-failure	8	361/362 passed, 1086.77 s

ShellSurfacePressureApplication.InputWithoutPressureRetainsExistingNonlinearBehavior 한 건이 output-busy (application exit 6)로 실패했다. 실패 output identity는 이전 classifier-correction workspace TEMP/TMP 아래였고, 실행 종료 뒤 live fesa, fesa_integration_tests, fesa_reference_tests process 및 해당 output directory는 없었다. 이 Step의 owned path 밖인 nonlinear application/integration failure이므로 source나 test를 변경하거나 terminal failure를 즉시 재실행하지 않았다.

순차 Full VERIFY는 CTest nonzero에서 중단했으므로 전체 pytest는 이번 실행에서 미실행이다. 이 operating-prep Step에는 external reference comparison이 적용되지 않으며, reference artifact를 읽거나 변경하지 않았다. 현재 source의 wrapper value는 14400, 등록 Stop JSON은 7500, shared validation/default command deadline은 각각 7200이다. 수동 test/build evidence와 registered Stop/Codex process exit는 별개이며, 후자는 이 보고서 시점에 미관찰이다.

Raw logs와 copied CTest LastTest.log는 ignored .harness/build/mitc4-eigen-evidence/prep/manual-20260906143832/에 보존했다. 현재 실행에서 변경한 tracked implementation artifact는 .codex/hooks.json과 이 보고서뿐이다. Phase Step result는 Executor history/timestamp를 보존한 채 error로 반환한다.

등록 Stop 관찰

후속 registered Stop (stop:9)도 같은 build directory에서 ctest --test-dir C:\\Users\\baram\\orca\\workspaces\\FESADev\\Eigen\\.harness\\build -C Debug --output-on-failure를 실행했다. 종료는 exit 8, 361/362 passed, real 982.52 s였고 동일한 ShellSurfacePressureApplication.InputWithoutPressureRetainsExistingNonlinearBehavior 만 실패했다. 따라서 새 등록 Stop deadline이 CTest 실행을 차단하지는 않았지만, 이 Step은 정상 terminal validation을 통과하지 못했다. Codex process의 최종 exit는 이 hook observation 자체로 주장하지 않는다.
