# 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: ready
- Done: implementation, verification and documentation
- Next: integrator no-ff merge and post-merge acceptance
- Blocked by:

## Handoff

- Commit: `e7cd967`
- Results: finalizer `28` cases / `1,000` timing iterations; all `58/58`
  autonomous headless regressions; facade/internal-access/shutdown/manifest;
  documentation `45`; coordination; checkpoint dry-run `7/7`.
- Remaining risks: private asset animation/visual/leak/p95/p99 evidence is absent;
  terminal Resource get/instantiation/repair stays synchronous; immediate prepared-
  candidate completion is a composition precondition; material lookup stays loader-owned.
- Documentation updated: new finalizer API/I/O/data-flow/state/sequence/dependency/
  ownership spec; pipeline, scene finalizer, cached observer, prototype cache,
  world renderer, module registry, `RENDER.md` and M03 Evidence.
