Contributor guide
Research direction
Start with ClickHouseAdaptiveQueryExecSuite.scala at line 766 and inspect the linked CI console log, especially the memory-release warning and shuffle-read assertion. Trace the failing test and determine the cause of the intermittent BuildRight/BuildLeft mismatch; done means the test no longer flakes and the relevant assertion passes reliably.
