Start with the three benchmark entries and source ranges in src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs, then run the documented benchmarks_ci.py command for DemoBenchmarks.TwoBodyConstraintBenchmarks. Compare the baseline and test commits and inspect the linked test report and graphs. Done means the reported Windows/x64 regressions are explained and the affected benchmark results no longer regress.
