+<!-- OPENWC_CLAIM:M03-RND-M2-NATIVE-ANIMATION-RESOURCE-OBSERVER-001:sindo-main-codex:2026-07-20 -->
+
+## Owner
+
+- Agent ID: `sindo-main-codex`
+- Target: M03 Renderer Facade and Safe Extraction
+- Branch: `work/sindo-main-codex/m03-m2-native-animation-resource-observer`
+- Worktree: `C:\Users\sindo\open-wc-worktrees\m03-m2-native-animation-resource-observer`
+
+## Outcome
+
+Move native GryphonRoost M2 animation candidate selection, synchronous raw read,
+native animated build, prototype/static-only adoption and debug diagnostics from
+the loader into a dedicated observer.
+
+## Non-goals
+
+- Change the exact native candidate predicate or add more animated models.
+- Move cached-GLB observation, ResourceLoader polling/finalize or playback.
+- Own attached instances, consume permits or change queue/batch behavior.
+- Change native parsing/building, cache formats, profiles or visible output.
+
+## Paths
+
+- Exclusive: `src/render/m2/m2_native_animation_resource_observer.gd`,
+  `src/tools/verify_m2_native_animation_resource_observer.gd`,
+  `docs/modules/m2-native-animation-resource-observer.md`, this claim
+- Shared: loader, M2 cached observer/snapshot/raw repository/prototype specs and
+  verifiers, world renderer, module registry, `RENDER.md` and M03 Evidence
+
+## Contracts and data
+
+- Only case-insensitive paths containing `gryphonroost` are native candidates.
+- Cached animated prototype wins; static-only state suppresses repeated reads.
+- Empty raw data or animated surfaces marks animation static.
+- Builder result must be non-null with at least one child; rejection marks static.
+- Successful result is adopted through first-wins prototype cache semantics.
+- Existing `M2_NATIVE_ANIM_CACHE` fields and debug gating remain exact.
+- Observer attaches/frees no Node and starts no async work.
+
+## Dependencies
+
+- Requires: accepted cached observer `6f385ed`, raw repository and prototype state
+- Blocks: remaining ResourceLoader polling/finalize extraction
+
+## Verification
+
+- Synthetic candidate/cache/static/raw/build/adoption/lifetime/logging/source and
+  timing contracts; adjacent M2/renderer gates; full headless suite and checkpoint
+  dry-run.
+
+## Documentation deliverables
+
+- Inline API docs; module API/I/O/ownership; data-flow/state/sequence/dependency
+  diagrams; adjacent renderer docs and M03 Evidence.
+
+## Status
+
+- State: active
+- Done: ownership/compatibility contract
+- Next: implementation, verification and documentation
+- Blocked by:
