Publish prepared GfxObj, Setup, CellStruct, and EnvCell collision records without retaining their parsed DAT BSP, polygon, vertex, or shape graphs. Strip temporary physics bundles at stable world commit, keep graph traversal only as an explicit test/tooling oracle, and report graph residency from actual retained fields.
Validated by 115 focused collision/streaming tests, a zero-warning Release build, and 8,413 passing Release tests with five pre-existing skips.
