ADO build 187778

A consistent change requires more than 20% median paired movement, at least 1 ms between the median runtimes, and at least 80% of pairs exceeding the relative threshold in the same direction. A slowdown without enough pair agreement is reported as inconsistent.

The displayed change is the median of paired before-and-after ratios. It is not recalculated from the two displayed median runtimes.

Unavailable or rejected data: Linux-SQL2022 (missing), Linux-SQL2025 (missing)

Both revisions use profiling-enabled builds on the same agent and database, with alternating order and discarded warmups. Results are diagnostic and do not represent production-wheel latency.

Raw samples and logs are attached to the ADO run as profiler-* artifacts.

🟡 Changes recommended

CI still downloads the 0.3.0 NuGet transport while installers require 0.4.0 wheel filenames, causing wheel validation or discovery failures.
