Deflake RepairGraceSparesInFlightCommit on loaded CI runners#19
Merged
Conversation
The commit raced wall clocks (sleep 10 ms vs 50 ms grace); a stalled CI thread overslept the whole window and the repairer legitimately stole the lock. Sync on a started flag and widen the margin to 100x (1 s grace); a maximally-delayed repairer now degrades to a vacuous pass instead of a failure.
