M03-RND-M2-NATIVE-ANIMATION-RESOURCE-OBSERVER-001

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.
