Start with src/benchmarks/real-world/bepuphysics2/SweepBenchmarks.cs and TwoBodyConstraintBenchmarks.cs, then run the provided benchmarks_ci.py commands for each filter on Windows/x64. Compare the reported results with the linked baseline and compare commits; done means the CapsuleCapsule and BallSocket regressions are understood and no longer reproduce or are appropriately addressed.
