Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs, especially the BallSocket benchmark at lines 91-104, and compare the listed baseline and compare commits. Run scripts/benchmarks_ci.py with the provided filter, then inspect the linked test report and profiling workflow documentation. Done means the regression cause is identified and the benchmark result is validated against the reported comparison.
