forbes-0023	f85dc047e8	fix(solver): enforce quaternion continuity on dragged parts during drag (#338 ) The _enforce_quat_continuity function previously skipped dragged parts, assuming the GUI directly controls their placement. However, Newton re-solves all free params (including the dragged part's) to satisfy constraints, and can converge to an equivalent but distinct quaternion branch. The C++ validateNewPlacements() then sees a >91 degree rotation and rejects the step. Two-level fix: 1. Remove the dragged_ids skip — apply continuity to ALL non-grounded bodies, including the dragged part. 2. Add rotation angle check beyond simple hemisphere negation: compute the relative quaternion angle using the same formula as the C++ validator (2*acos(w)). If it exceeds 91 degrees, reset to the previous step's quaternion. This catches branch jumps where the solver finds a geometrically different but constraint-satisfying orientation (e.g. Cylindrical + Planar with 180-degree ambiguity). Verified: all 291 solver tests pass.	2026-02-27 09:37:10 -06:00
