Research direction

The report only identifies a MySQL multithreading case and includes a screenshot; it names no files, tests, or entry points. Start by reproducing the case and tracing how the reader and writer tables are selected across threads. Done means the selected read and insert tables remain aligned under concurrent execution, with a regression test for the reported scenario.
