# M03-RND-WMO-SCENE-RESOURCE-FINALIZER-001

<!-- OPENWC_CLAIM:M03-RND-WMO-SCENE-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-wmo-scene-resource-finalizer`
- Worktree: `C:\Users\sindo\open-wc-worktrees\m03-wmo-scene-resource-finalizer`

## Outcome

Move cached WMO PackedScene terminal ResourceLoader polling, probe validation,
probe lifetime and scene/missing publication from the loader into one service.

## Non-goals

- Change `.tscn` path selection, file-size admission or request start behavior.
- Own live fallback, placement/build jobs, attached Nodes or scheduler permits.
- Change WMOBuilder cache metadata/version rules or visible output.
- Merge PackedScene and lightweight render Resource finalization generically.

## Paths

- Exclusive: `src/render/wmo/wmo_scene_resource_finalizer.gd`,
  `src/tools/verify_wmo_scene_resource_finalizer.gd`,
  `docs/modules/wmo-scene-resource-finalizer.md`, this claim
- Shared: loader, WMO scene cache state spec/verifier, world renderer registry/spec,
  `RENDER.md`, M03 Evidence

## Contracts and data

- Pending requests are polled in detached Dictionary insertion order.
- Only LOADED/FAILED statuses complete requests.
- Failed, null, non-PackedScene, non-Node3D and stale scenes publish missing.
- Accepted PackedScenes retain exact Resource identity.
- Validation instantiates once and releases accepted/rejected Node3D probes once.
- Admission, oversize logging, live fallback and shutdown order are unchanged.

## Dependencies

- Requires: accepted WMO scene Resource cache state
- Blocks: remaining loader-owned WMO live fallback/materialization cleanup

## Verification

- Synthetic status/order/type/probe/validation/lifetime/adoption/source/timing
  contracts; adjacent WMO/renderer gates; full 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: merge and post-merge acceptance
- Blocked by:

## Handoff

- Commit: `7779e9e` (`render: extract WMO scene resource finalizer`)
- Results: finalizer PASS `cases=26 iterations=1000 elapsed_ms=4.186`;
  adjacent WMO scene/render cache/finalizer/queue/planner/registry/resolver and
  shutdown checks passed; autonomous headless suite `61/61`; documentation `48`;
  coordination passed with `34` historical warnings; checkpoint dry-run `7/7`.
- Remaining risks: PackedScene probe validation remains synchronous main-thread
  work; no serialized private WMO stale/oversize, long leak, visual,
  descriptor-pressure or p95/p99 evidence was added.
- Documentation updated: new full module specification with API/I/O and
  data-flow/state/sequence/dependency diagrams; adjacent WMO cache/world-renderer
  specs, module registry, `RENDER.md` and M03 Evidence.
