STALL_ESCALATION_REQUIRED

• Exact head: 7744b637e4dea0e1bfd8b0d7b667a7d87e0bdf39
• Merge state: MERGEABLE / CLEAN; GitHub Actions rollup is complete and successful or skipped; active non-outdated review threads: 0.
• Live blocker: seven head check suites remain QUEUED (external-app suites: Claude, Render, Cursor, MistralAI, CodeRabbit, Renovate, plus an unnamed suite). This blocks the normal release merge gate even though gh pr checks omits them.
• Ordinary owner: Reviewed Repo Orphan PR Steward has no safe branch or rerun action while those suites are externally queued.
• Receiving worker: Reviewed Repo Stall Escalator is ACTIVE hourly (BYMINUTE=50).
• Next diagnostic question: which queued external suite(s) are required by branch protection or have a zero-job/startup-failure condition, and can their provider or workflow be recovered without bypassing required review?
