- Qualify bare "object" as builtins.object in bpy.types to avoid shadowing by Context.object and similar properties - Use _Sequence alias import to fix mypy "collections.abc.Sequence not defined" - Filter out variables that clash with submodule re-exports (e.g. bpy.app) - Add 5.0 conformance tests from Blender 5.0 mathutils documentation Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
