• Outcome: blocked-environment

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.
