Research direction
Start by running TestCacheLongKeyLIRS and inspect testScanResistance around line 401, using the reported stack trace to follow the failing assertion. Reproduce the CI failure and determine what makes the assertion fail at i: 18; done means the test passes reliably without weakening its checks.
