Start with the PowerBI Dashboard and the listed mTls-handshakes-kestrel, single_query, and updates benchmark results, then compare the dependency changes between the referenced builds. The issue does not name source files, tests, or a requested fix, so completion criteria are not specified beyond identifying the regression and its cause.
