# M03-RND-M2-ANIMATION-RESOURCE-FINALIZER-001
<!-- OPENWC_CLAIM:M03-RND-M2-ANIMATION-RESOURCE-FINALIZER-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-animation-resource-finalizer`
- Worktree: `C:\Users\sindo\open-wc-worktrees\m03-m2-animation-resource-finalizer`
## Outcome
Move cached animated M2 ResourceLoader status polling, terminal Resource load,
candidate finalization, prototype/static-only adoption and success diagnostics
from the loader into a dedicated two-phase finalization service.
## Non-goals
- Change cached animation eligibility, request admission or native-first order.
- Move material-prototype lookup, permit ownership, playback or materialization.
- Change ResourceLoader status order, cache formats, profiles or visible output.
- Generalize static and animated ResourceLoader paths behind callbacks/frameworks.
## Paths
- Exclusive: `src/render/m2/m2_animation_resource_finalizer.gd`,
`src/tools/verify_m2_animation_resource_finalizer.gd`,
`docs/modules/m2-animation-resource-finalizer.md`, this claim
- Shared: loader, animation pipeline/scene finalizer/prototype cache/cached
observer/world-renderer specs and verifiers, module registry, `RENDER.md`, M03 Evidence
## Contracts and data
- Pending request snapshots are polled in existing Dictionary insertion order.
- Empty Resource paths are discarded and marked static-only immediately.
- Only LOADED/FAILED statuses move into completion-order finalize FIFO.
- One permit processes one popped terminal record, including skipped/stale records.
- Existing prototype/static-only state suppresses terminal Resource loading.
- LOADED Resource is instantiated before material-prototype lookup is requested.
- Candidate repair/finalize/adoption and exact `M2_ANIM_CACHE` debug fields remain.
- Rejected candidates are released by the existing animated scene finalizer.
## Dependencies
- Requires: accepted animation pipeline, scene finalizer, cached/native observers
- Blocks: remaining loader-owned M2 material-prototype lookup and action execution
## Verification
- Synthetic polling/status/FIFO/skip/load/candidate/repair/adoption/log/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
