- Disabled constraints for the stickman rig's head bone to allow for smoother animations.
- Improved mode transitions in the sandbox stage to preserve stickman poses between EDIT and DIRECT modes.
- Added side profile stabilization for knee bends in the ragdoll component to prevent unnatural poses during physics interactions.
- Enhanced the snap-to-standing functionality to restore the stickman's original pose accurately.
- Introduced new tests for validating pose preservation during mode transitions and ragdoll behavior during walking animations.
- Created a new scene for testing stickman bending and ragdoll transitions.
- 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.
- Implemented `MissingStickmanPlaceholder` class to visually indicate missing stickman assets in the scene.
- Created `StageSceneIO` class for handling JSON serialization and deserialization of stage documents, including encoding and decoding of actions and rules.
- Added tests for vector handling, rule encoding/decoding, safe file writing, root validation, and handling of missing assets.
- Introduced a new stickman asset file `bad.stk` for testing purposes.
- Enhanced test coverage for phase 5 file features, ensuring robust handling of scene data and missing assets.
