- Migrated 21 node files to V3 architecture
- All nodes now inherit from io.ComfyNode
- Replaced INPUT_TYPES() with define_schema() returning io.Schema
- Standardized all execution methods to execute() classmethods
- Updated returns to use io.NodeOutput
- Renamed VALIDATE_INPUTS -> validate_inputs, IS_CHANGED -> fingerprint_inputs
- Updated __init__.py to use ComfyExtension with comfy_entrypoint()
- Removed __init__ methods (V3 nodes are stateless)
- Added OpenSpec proposal documenting the migration
