-| 2026-05-01T00:46:00Z | opus-4-7 / session continuation | 98fc7424 | Thread-audit + 3-PR fix tick. Per the discipline lesson from earlier ticks (BLOCKED-with-green-CI = audit threads), checked unresolved threads on top BLOCKED PRs: (1) #989 col3 = '(none — pivot tick)' instead of 8-char cron-id — same class as last tick's col3 fixes; replaced with 98fc7424 + thread resolved. (2) #968 body inconsistency — claimed 'Five PRs in this tick's window, four still in CI' but row breakdown shows 2 MERGED + 3 armed = 5 total, 3 in CI not 4; fixed off-by-one + thread resolved. (3) #991 P0 'starts with 1 || not | <ts> |' — false positive (Copilot mis-parsed line-number-prefix view as table content); form-2 close. Queue at 26 (24 BLOCKED + 2 ancient DIRTY). Cron 98fc7424 healthy. | #968 + #989 (1-line content fixes), #991 (form-2 close) | Observation — third tick in a row applying the BLOCKED-with-green-CI investigate-threads-first discipline. Findings keep coming because Copilot re-evaluates after every force-push and after every base-branch update. The queue isn't stuck; the threads are accumulating on a rolling basis. Discipline: every tick during queue-saturation, audit threads on BLOCKED PRs. The signal-to-merge lag pattern (~1-2 ticks once threads resolve) is consistent with the last 2 ticks' observation. |
