# M03-RND-M2-CACHED-ANIMATION-RESOURCE-OBSERVER-001

<!-- OPENWC_CLAIM:M03-RND-M2-CACHED-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-cached-animation-resource-observer`
- Worktree: `C:\Users\sindo\open-wc-worktrees\m03-m2-cached-animation-resource-observer`

## Outcome

Move cached-GLB animated M2 lookup, allow/deny and primitive/schema safety
selection, threaded request admission and static-only transition from the loader
into a service that produces `M2BuildResourceSnapshot`.

## Non-goals

- Move native GryphonRoost raw-data build, debug logging or finalize drains.
- Own/free prototype Nodes or change cache/pipeline ownership.
- Change allow/deny defaults, primitive limits, candidate order or GLB rules.
- Change batching, permits, cache formats, profiles or visible output.

## Paths

- Exclusive: `src/render/m2/m2_cached_animation_resource_observer.gd`,
  `src/tools/verify_m2_cached_animation_resource_observer.gd`,
  `docs/modules/m2-cached-animation-resource-observer.md`, this claim
- Shared: loader, M2 snapshot/animation pipeline/prototype specs and verifiers,
  world renderer, module registry, `RENDER.md` and M03 Evidence

## Contracts and data

- Cached animated prototype wins; static-only and pending states do not request.
- Empty allowlist rejects; denylist wins; matching is stripped/case-insensitive.
- Historical nested/lowercase/basename `.glb` order remains exact.
- Candidate requires animations, primitive limit and accepted empty or
  `pivot_prefix_v1` schema; other schemas are rejected.
- Successful/`ERR_BUSY` request is remembered and reported pending; no usable
  candidate or request failure marks animation static.
- Service produces a snapshot borrowing the exact prototype and frees nothing.

## Dependencies

- Requires: accepted static observer `5ebf4de`, snapshot and animation pipeline
- Blocks: native animation observation and remaining finalize extraction

## Verification

- Synthetic cache/pipeline/snapshot lifecycle, policy/path/GLB metadata fixtures,
  source boundaries and timing; 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.
