Start by running the provided benchmarks_ci.py command for DemoBenchmarks.TwoBodyConstraintBenchmarks and compare the baseline and compare commits. Inspect TwoBodyConstraintBenchmarks.cs at the linked benchmark ranges and use the linked test report and profiling workflow documents; done means determining the cause of the three measured regressions and verifying the benchmark results after the fix.
