+
+<!-- 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: active
+- Done: ownership/compatibility contract
+- Next: implementation, verification and documentation
