coord(M03): claim raw M2 model repository

Work-Package: M03-RND-M2-RAW-MODEL-REPOSITORY-001
Agent: sindo-main-codex
Tests: coordination gate passed before claim
Fidelity: native-boundary extraction only; parser methods and paths unchanged

+# M03-RND-M2-RAW-MODEL-REPOSITORY-001 — raw M2 model repository
+
+<!-- OPENWC_CLAIM:M03-RND-M2-RAW-MODEL-REPOSITORY-001:sindo-main-codex:2026-07-20 -->
+
+## Ownership
+
+- Target: M03
+- Program: RND
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m03-m2-raw-model-repository`
+- Lease expires UTC: 2026-07-20
+- Integrator: M03 milestone integrator
+
+## Outcome
+
+Extract the repeated FileAccess/ClassDB native `M2Loader` boundary for static
+and animated raw model Dictionaries from `StreamingWorldLoader`.
+
+## Non-goals
+
+- Cache raw data, Meshes, prototypes, missing paths or animation decisions.
+- Build Nodes/Meshes, refresh materials or choose `.tscn/.glb` caches.
+- Change static/animated parser methods, path resolution or fallback order.
+- Add dependencies, persistence, retries or visible behavior.
+
+## Paths
+
+- Exclusive: `src/render/m2/m2_raw_model_repository.gd`,
+  `src/tools/verify_m2_raw_model_repository.gd`,
+  `docs/modules/m2-raw-model-repository.md`, this claim
+- Shared/hotspots: `src/scenes/streaming/streaming_world_loader.gd`, M2
+  finalizer/extractor/cache/pipeline/material/animation/shutdown verifiers and
+  module specs, `docs/modules/world-renderer.md`, `docs/modules/README.md`,
+  `RENDER.md`, `targets/03-renderer-facade.md`
+- Generated/ignored: `.godot`, native DLL, generated M2 resources, caches and
+  proprietary renderer corpus
+
+## Contracts and data
+
+- Static load calls native `load_m2`; animated load calls `load_m2_animated`.
+- Paths remain `globalize_path(extracted_directory.path_join(normalized_path))`.
+- Empty path, missing native class/file/instance/method, parse failure or
+  non-Dictionary result returns an empty Dictionary without retained state.
+- Each successful request creates one native loader instance as before.
+
+## Dependencies
+
+- Requires: accepted runtime Mesh finalizer package on master `1d94eac`
+- Blocks: M2 prototype/cache state extraction
+- External state: native M2Loader registration and local extracted files
+
+## Verification
+
+- Commands: dedicated invalid/missing/class/source/timing verifier; finalizer/
+  classifier/extractor/cache/pipeline/material/animation/shutdown/M2 build/facade/
+  internal-access/manifest, documentation and coordination gates
+- Fixtures: empty/missing normalized paths plus source contract; proprietary
+  success corpus remains external
+- Fidelity evidence: exact native method names, path expression and three caller transitions
+- Performance budget: 10,000 rejected empty-path calls under 1 second
+
+## Documentation deliverables
+
+- Inline public API docs
+- Module specification with inputs/outputs, ownership and source map
+- Data-flow, lifecycle/state, sequence and dependency diagrams
+- Finalizer/extractor/cache/pipeline, world-renderer, registry and RENDER updates
+
+## Simplicity and naming
+
+- Important name introduced: `M2RawModelRepository`
+- Simplest solution: one stateless RefCounted with static and animated load methods
+- Rejected complexity: generic native repository, caching, dependency injection,
+  retries, diagnostics framework or async wrapper
+- Unavoidable complexity: animated native method availability is a distinct guard
+- Measured optimization evidence: bounded rejected-input loop
+
+## Status
+
+- State: claimed
+- Done: refresh/static-prototype/native-animation M2Loader paths identified
+- Next: implement repository, migrate adapters, verify and document
+- Blocked by:
