Flaky test Triage - 2026-09-17 #20366
Description
This issue was generated automatically by Claude Code (Anthropic's AI coding agent) running a scheduled CI-triage routine on behalf of @FrankChen021. Analysis and suggested fixes are AI-produced; please verify before acting on them.
This triage covers the 14 commits merged to master on 2026-09-16. One commit had a failed job: a push-triggered unit-test shard. The commit did not cause it. It is a known count-snapshot race in TaskQueueScaleTest that has also failed on other PRs, and the same shard passed on the neighbouring master commits before and after, and on the PR's own pre-merge run. No re-runs had been triggered.
