The 10th idle tick is a pure audit/maintenance tick (no code changes), so the idle ladder #5+ applies: skip pytest/ruff/guard, and instead run git status + git log origin/main..HEAD + fresh hilo stats (94/21) + scheduler/CI live checks, then persist everything to the DuckDB board, export parquet, commit only events.parquet, record last_commit post-commit (Phase-2), and push both artifacts. Cooldown (7200 s) is read from fleet.toml and never PUT (admin intent; PUTs revert).

Edge cases tested:
- **First insert on empty table** → `id=1` (`COALESCE(MAX(id),0)+1`); second tick → `id=2`.
- **Naive-UTC** → row ts `2026-08-01T22:31:38` matches `^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}$` (DuckDB `now()` = UTC, no tz suffix).
- **Dup guard** → replay of tick 45: `[dup]`, `COUNT=1, MAX(id)=1`, no new commit (`git rev-parse HEAD` unchanged).
- **Cooldown order** → a replay is blocked by cooldown first (`[skip]`), dup-guard catches crash-retries that pass cooldown.
- **`git add -f` only** → `git show --name-only HEAD` == `["events.parquet"]`; staged-set assert is a hard fail otherwise.
- **Phase-2** → `board_meta.last_commit` equals the post-commit SHA (`git rev-parse HEAD`) and `git log origin/main..HEAD` is empty (pushed).
- **Push both** → `git push origin HEAD:main` + `board.db`/`events.parquet` copied to sync dir.
