+FCM-M2-002 actionable delta: Stack PR #773 exists at frozen head 23d58cdb9083f2978662013103788ae176df8aca, tree bf44b0efeebf87185c672cbba2ba19b76735c4ab. Exact-head Woodpecker pipeline 1829 is terminal red: 2/794 tests relied on chmod 0500 to force projection failure, but CI runs as root so projection succeeded. Same sole owner prepared a one-file test-only deterministic injected-failure remediation, staged synthetic tree 1b9ebe4fa1a90734b6f81118e120bae5290cd350; product bytes and remote head remain unchanged while fresh independent review runs. No merge, M3, site, canary, deploy, migration, runtime, or remote authority.
