MC-4413

Watchdog false-alarm — already remediated, no code change. Two events on social-pulse 2026-05-29: (1) 05:30 scheduled run failed — NotebookLMClient.from_storage() auth token expiry (same Google token-expiry family as oauth-health-check this morning). (2) 07:28 "failure" in this ticket = shepherd INTENTIONALLY cancelling the duplicate untracked scheduler self-heal runtime after MC-4402 became the canonical worker-owned rerun (dedup working as designed, not a bug). MC-4402 re-authed NotebookLM/Google and reran → today's audio delivered: audio-library/social/2026-05-29-social-pulse.mp3, 43MB, written 07:39 (matches MC-4402 completion ~07:38). Recurring pattern: 05:30 run also failed 05-22 and 05-27 on the same NotebookLM auth expiry — the daily fail→self-heal cycle works but is noisy. If it recurs, fix is a longer-lived/auto-refreshed NotebookLM token rather than per-day re-auth; not actioning now (covered by oauth-health-check auto-suspend + MC-4402). Recommend closing this watchdog ticket.

Gated — confirmed watchdog false-alarm, no code change. Two 2026-05-29 social-pulse task_runs, both explained, neither a live defect: - 05:30 failed = real NotebookLM token-expiry (Failure 1/3) — the SAME Google auth family fixed under MC-4402 (re-auth done, GWS OK 07:47). - 07:28 failed = intentional shepherd cancel of a duplicate untracked self-heal/scheduler runtime, deliberately yielding to MC-4402's canonical worker-owned rerun to avoid competing NotebookLM/audio generation. Remediation proof: canonical rerun produced audio-library/social/2026-05-29-social-pulse.mp3 = 43.5MB at 07:39 (post-re-auth). Pipeline healthy. Task enabled:true; next scheduled run (tomorrow 05:30) runs against fixed auth and will reset the consecutive-fail counter. Superseded by MC-4402. Closing.

Shadow reviewer verdict: FAIL (cycle 1/3). Reopening for fixes. Reasons: The worker claims the ticket is a watchdog false-alarm requiring no code change, but there is no committed change (done_sha is none captured, diff is unavailable). The instructions explicitly state to never return pass when there is no committed change to inspect. While the explanation is plausible, accepting it without any verifiable code or committed artifact violates the core review requirement to assess actual work rather than untrusted claims. Gaps: - No committed change or done_sha captured for inspection - No diff available to verify the claim that no code change was needed - No test evidence or smoke test results provided - Worker claims 'no code change' but there is no way to independently verify the remediation or that the underlying issue (token expiry) is actually resolved

Shepherd gate: closing this watchdog wrapper as duplicate/noise, not a live blocker. The failed task_run was intentionally produced when the shepherd cancelled a duplicate untracked social-pulse self-heal/runtime after MC-4402 became the canonical recovery lane. MC-4402 is already gated done with NotebookLM/GWS auth verified and a real social-pulse MP3 rendered; no human input or additional worker is required here.

Shepherd gate: verified MC-4413 is a duplicate/watchdog false alarm, not a new blocker. The 07:28 social-pulse failure row was the intentional duplicate-runtime cancellation while MC-4402 owned the canonical NotebookLM/Google re-auth rerun. MC-4402 is done, and the user-facing artifact exists: audio-library/social/2026-05-29-social-pulse.mp3 (43,558,435 bytes, written 07:39 SAST). Closed MC-4413 as done, cleared stale non-owning done_sha metadata, and retired its idle runtime.
