# Worklog: omp-completion-hooks

Status: complete

## Objective

Codex and OMP main sessions use one completion checker, and OMP continues unverified stop attempts through its documented eight-continuation budget.

Stopping condition: focused contracts, shared checker, repository-root discovery smoke, Darwin removal of the global link, and final upstream/tag verification pass.

## Decisions

- Use one shared shell checker for Codex and OMP.
- Keep the OMP gate as a repository-local post-hook at `.omp/hooks/post/completion-gate.ts`; do not install it through Nix or user-wide OMP configuration.
- Verification is a one-shot content snapshot consumed by the next stop attempt.
- Do not patch OMP core; use the public `ExtensionAPI.session_stop` continuation budget.
- Preserve `features.unexpectedStopDetection: true`; do not add another semantic classifier.
- Pre-existing working-tree changes: none (`git status --short --branch`).

## Evidence

- Red contract: `python3 -m unittest tests/test_completion_hooks.py` failed in 1.2s for the expected missing `scripts/completion-check`, missing OMP gate hook, and absent `CODEX_STOP_CHECKER` seam. The first attempt exposed recursive unittest invocation in the old wrapper and timed out; the fixture now stubs the legacy checker commands so red failures are bounded and relevant.
- `bun test tests/omp_completion_gate.test.js`: 15 passed.
- `python3 -m unittest tests/test_completion_hooks.py`: 9 passed, including the Bun bridge.
- `scripts/completion-check`: 23 repository tests passed, then Darwin `hey check` passed; direct execution succeeded with checker output confined to stderr.
- `hey agent-audit-tests tests/test_completion_hooks.py tests/omp_completion_gate.test.js`: `PASS test-confidence`.
- `hey agent-finish --worklog .agents/worklogs/omp-completion-hooks.md`: all applicable workflow checks passed after `nix develop -c true` refreshed the generated prek manifest.
- Corrective Darwin rebuild removed the global completion-gate link; `~/.omp/agent/extensions` contains no completion gate.
- Fresh repository-root post-hook smoke settled as exact `HOOK_OK`, proving `.omp/hooks/post/completion-gate.ts` supplies `registerTool` and `session_stop` through OMP's extension runner.
- Fresh post-hook `omp --cwd config` smoke settled as exact `PRECHECK`, confirming project-hook discovery remains repository-root scoped.

## Reviews

- Plan gate blocked twice at ACP session creation: default reviewer and `--reviewer gemini` both returned `Authentication required`. Tooling waiver: execute the already approved, contract-complete plan; retry the required landing gate.
- Landing gate blocked twice at ACP session creation: default reviewer and `--reviewer gemini` both returned `Authentication required`. No model review findings were available; focused contracts, semantic diff inspection, workflow checks, rebuild, and live continuation smoke remain the evidence-backed waiver.

## Feedback

- None.

## Remaining work

- None.

## Commits

- `feat(agents): enforce OMP completion checks`
- After landing: `agent-work/omp-completion-hooks`.
