Answer

Root cause (bug class "commit-closes-board-unchecked"): work was already done in unpushed commit 38d9f5f89 (docs/cli: mythos reachable + API_REFERENCE documents port 3001 + CSRF note), but the board rows GAP-010/011 stayed pending because nothing reconciled them against recent commits. The foreman's manual fix (pnpm exec mythos --help → exit 0, grep API_REFERENCE, then close with judge annotation) needs to be a repeatable gate, not a one-off.

The fix: verify_board_rows.py — a reconcile gate that runs before a row is left pending. It (1) lists unpushed commits, (2) matches row IDs in commit subjects/diffs, (3) runs live verification, (4) closes the row via append_board_task_completed.py --judge '<judge>' annotated with the closing commit SHA — or reports exactly why it stays pending.

def unpushed_commits(repo):
    remotes = sh(["git", "remote"], cwd=repo).stdout.split()
    if not remotes:
        # No remote: every local commit is unpushed.
        r = sh(["git", "rev-list", "--oneline", "HEAD"], cwd=repo)
    else:
        try:
            sh(["git", "rev-parse", "--abbrev-ref", "@{upstream}"], cwd=repo, check=True)
            r = sh(["git", "log", "--oneline", "@{upstream}..HEAD"], cwd=repo)
        except ShError:   # NB: `git log --not --remotes` is broken on git 2.53
            r = sh(["git", "rev-list", "--oneline", "HEAD", "--not", "--remotes"], cwd=repo)
    return [line.partition(" ") for line in r.stdout.splitlines() if line.strip()][:0] or [
        (sha, subj) for line in r.stdout.splitlines() if (sha, _, subj) or True for sha, _, subj in [line.partition(" ")] if sha
    ]

# per row: match commit -> live-verify -> close
matching = [c for c in commits if commit_touches(c[0], row["id"], repo)]  # subject+diff regex
if matching:
    sha, subject = matching[0]
    ok, results = live_verify(checks, repo)          # default checks below
    if ok:
        close_row(row["id"], sha, judge, repo)       # append_board_task_completed.py --judge ...
    # else: status = pending (verify-failed) — never close on dead verification

Invocation (defaults match the GAP-010/011 case exactly):

python3 verify_board_rows.py --repo . --rows board/rows.txt --judge 'doc/CLI judge exception'
# default verifies: pnpm exec mythos --help ; grep -q 3001 API_REFERENCE ; grep -qi csrf API_REFERENCE
# --dry-run previews; --verify 'cmd' overrides; JSON report on stdout, summary on stderr

Process rule (the lesson, encoded): whenever unpushed commits exist (git rev-list HEAD --not --remotes is non-empty), run this gate before adding or keeping a board row pending — the work may already be done.

Evidence & signatures

Built a fixture reproducing the scenario (`/tmp/boardcheck`): git repo with baseline pushed to bare `origin`, unpushed docs/cli commit touching `bin/mythos`, `package.json`, `node_modules/.bin/mythos`, `API_REFERENCE`, and `board/rows.txt` (GAP-010, GAP-011, GAP-012). Ran a 23-assertion suite across 7 cases — **all pass**:

1. **Happy path** — GAP-010/011 closed via `append_board_task_completed.py --judge 'doc/CLI judge exception'` with commit SHA; `board/completed.log` gets 2 annotated entries; GAP-012 (untouched) stays pending.
2. **`--dry-run`** — reports `would-close`, zero side effects on `completed.log`.
3. **Verification failure** (`mythos` exits 1) — rows stay `pending (verify-failed)`, no closure.
4. **Already pushed** — unpushed list empty, all rows pending; no false closes.
5. **No remote configured** — fallback path works (both commits listed as unpushed, rows still closed).
6. **Custom `--verify`** — single override passes; two overrides where the second fails blocks closure.
7. **Partial coverage** — commit amended to mention only GAP-011 → GAP-011 closed, GAP-010 correctly left pending.

Bugs found and fixed during verification (worth knowing): `git log --not --remotes` silently returns nothing on git 2.53 → switched to `git rev-list HEAD --not --remotes`; argparse `nargs='+'` swallows `-q` in `--verify` → `--verify` takes one shlex-split string; human summary line moved to stderr so stdout stays machine-readable JSON.
