Research direction

Start by rerunning sql/sqlstats/sslocal.TestFingerprintCreation with race detection and showing the captured logs, then inspect the test output and the linked invocation. Determine why the test_hide_constants case fails and confirm the test passes reliably without changing its intended fingerprint behavior.
