Jira issue: CRDB-68504

Start with pkg/server/storage_api/storage_api_test.TestLivenessAPI and inspect the captured logs from the linked test report. Read health_test.go around line 140, slinstance.go around line 381, and the test_server_shim.go comments to understand the session-record deletion. Done means the liveness test passes reliably under the reported race, shard, and run conditions.
