Research direction

The issue names no source file, test, or code entry point. Start with the tls-renegotiation-kestrel results and the linked PowerBI Dashboard, comparing the old and new RPS values and the listed Updates dependency. Done means identifying the cause of the regression and confirming that the benchmark no longer shows it.
