- Added new scene file `test_fall.scene` for testing airborne dynamics.
- Created architecture proposal in `PHASE_6a_AIRBORNE_LANDING.md` detailing airborne momentum, procedural air pose, and landing impact absorption mechanics.
- Developed specifications in `phase_6a_airborne_landing.md` outlining implementation decisions, targets, and static contracts for the airborne system.
- Introduced focused regression tests in `test_phase6a_airborne_landing.gd` to validate airborne pose, momentum, landing timeline, and queue behavior.
- Ensured all tests pass with 100% assertion success.
- Created a new scene file `ramp.scene` with terrain and stickman objects, including event rules for ragdoll and recovery actions.
- Documented Phase 6 implementation in `PHASE_6_GROUND_SNAPPING.md`, detailing the continuous dynamic IK, terrain-following locomotion, and constraints for stickman rigs.
- Defined scene structure, layered IK ownership, probe contracts, and per-frame solve order for terrain interaction.
- Verified functionality for terrain snapping, stance/swing blending, pelvis/root compensation, and navigation synchronization.
