## Summary

personalrobotics/sscbirrt released v3.8.0, which makes motion validation public as sscbirrt.Validator, able to validate states, motions, paths, and timed trajectories; the planner returns a path or trajectory only after the validator accepts it. Edge subdivision now includes a rounding tolerance, reducing search state checks on benchmark problems by 4-14% (about 1% for door), with all problems still succeeding 100%; seeded paths differ from 3.7, while reference artifact cases and states are unchanged.
