# Recent Log Failure Fix Baseline - 2026-05-20

## Scope

This baseline records fixes applied after reviewing local oh-my-pr logs for the 24-hour window ending May 20, 2026.

Implementation branch:

- `fix/log-plan-implementation`
- Base: `origin/main@72e2b5b9df3596961c5b8298ac6241df7c1d0862`
- Recorded at: `2026-05-20T15:29:35Z`

## Fixes Applied

### Watcher Lifecycle Observability

The app runtime now logs watcher start, heartbeat, and stop events with the configured poll interval.

Expected future signal:

- Each runtime start with background jobs enabled emits `Repository watcher started`.
- Each interval emits `Repository watcher heartbeat`.
- Runtime shutdown emits `Repository watcher stopped`.

### CI Timeout Diagnostics

CI timeout warnings now include pending check names and statuses when check snapshots are available.

Expected future signal:

- `Timed out waiting for CI checks to complete` identifies the checks that are still pending.
- The run metadata includes `pendingChecks` for timeout analysis.

### Repeated No-Op Babysitter Runs

No-op babysitter runs now record a PR/head marker, and the repository watcher skips requeueing the same unchanged head when feedback and CI are still clean.

Expected future signal:

- After a no-op babysitter run for a PR head SHA, the watcher logs `Skipping babysitter run because the same PR head was already checked with no necessary fixes`.
- New review feedback, failing checks, or a new head SHA still allow another babysitter run.

### Git Stderr Log Severity

Successful command stderr is now logged at `info`; failed commands still emit an error summary.

Expected future signal:

- Normal git progress output on stderr no longer inflates warning counts.
- Failed commands remain visible as errors.

## Verification

Commands run from `.worktrees/log-plan-implementation`:

```bash
node --test --import tsx server/appRuntime.test.ts server/babysitter.test.ts --test-name-pattern "watcher lifecycle|unchanged PR heads|pending check details|successful git stderr"
node --test --import tsx server/appRuntime.test.ts server/babysitter.test.ts server/backgroundJobHandlers.test.ts server/backgroundJobDispatcher.test.ts
npm run check
npm run test
```

Results:

- Focused regression suite passed: 94 passed, 0 failed.
- Adjacent background-job suite passed: 116 passed, 0 failed.
- TypeScript check passed.
- Full server suite passed: 468 passed, 1 skipped, 0 failed.

## Future Log Review Boundary

For future local-log analysis, treat log rows before this branch lands as pre-fix evidence. Only count these as regressions if they appear after the merge commit for `fix/log-plan-implementation`:

- Repeated babysitter jobs for the same clean PR/head after a no-op run marker exists.
- CI timeout warnings that do not identify pending checks when snapshots are available.
- Missing watcher lifecycle logs while background watcher startup succeeds.
- Successful git progress output classified as warnings.
