- Correct squared-distance objectives and separate value and parameter
tolerances.
- Reuse spline span data and unchanged PSO objective evaluations.
- Preserve seam pcurve maxima and report failed interval searches.
- Correct closed-surface seeds and singular-boundary projection.
- Fix stationary endpoint transitions and HLR surface sampling.
- Preserve stable blending point references with indexed storage.
- Reuse mesh points and normals and evaluate initial nodes by knot span.
- Add regression tests, update references and mark unresolved failures.
