CollisionComponent
Exact USDA block introduced by RCP plus fixture-backed contract evidence.
Quick Read
CollisionComponent has 7 fields.
5 written in baseline, 2 sparse-only (emitted only when changed).
Authored as def RealityKitComponent "Collider" with info:id = "RealityKit.Collider".
For large components, prefer fixtures.csv for fixture-by-fixture authored rows and matrix.csv for the derived variant matrix.
