 * Check the G7 review queue against the live corpus.
 *
 * Exit 0 = every open entry still anchors to real text; exit 1 = drift or a
 * schema fault. Drift is a finding, never a silent pass: an entry that stops
 * matching is exactly the case G7 exists to prevent — a real defect leaving the
 * programme unnoticed because someone edited around it.
 *
 * Read-only. Nothing in the queue is machine-appliable; resolution is a human
 * review act (form b, ratified 2026-08-03).
