Research direction

Start with the benchmark workflow in docs/benchmarking-workflow-dotnet-runtime.md and the scripts/benchmarks_ci.py command shown in the issue. Reproduce the listed SCD Publish and Build filters on Windows, then compare the supplied baseline and test reports to identify the regression; done means the cause is understood and the reported performance regression is resolved or triaged.

Written by the indexing model from the issue text.
