Parameters:

• attempt=1
• race=true
• run=2
• shard=8

Start with the sql/stats.TestCacheAutoRefresh failure and its linked test report, then trace the stack through pkg/util/admission/work_queue.go:1104 and pkg/kv/kvserver/kvadmission/kvadmission.go:412. Investigate why the test stalls or fails under race mode and confirm the test passes reliably on the affected basalt branches.
