+- `M2RawModelRepository` now owns the repeated extracted-file and optional
+  native `M2Loader` boundary for static `load_m2` and animated
+  `load_m2_animated` raw Dictionaries.
+- `StreamingWorldLoader` delegates the stale-Mesh refresh, static prototype and
+  native animated prototype reads. It retains normalization, `.tscn/.glb`
+  fallback order, missing/prototype caches, builders, permits and Node/Mesh use.
+- The repository retains no path, native object or parsed data. Empty paths,
+  absent files/classes/methods and invalid results produce the same empty-value
+  fallback contract; path join/globalization and native method names are exact.
+- No cache format, parser, material, geometry, animation or visible rule changed.
+  Synthetic missing-input timing is not asset-backed I/O/p95/p99 or fidelity evidence.
