+<!-- OPENWC_CLAIM:M03-RND-M2-MESH-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-mesh-resource-finalizer`
+- Worktree: `C:\Users\sindo\open-wc-worktrees\m03-m2-mesh-resource-finalizer`
+
+## Outcome
+
+Move static M2 ResourceLoader status polling, terminal Resource/Mesh extraction,
+runtime Mesh preparation, Mesh-cache adoption and missing outcome from the
+loader into one dedicated finalization service.
+
+## Non-goals
+
+- Change static cache path selection or threaded request admission.
+- Merge static and animated terminal services behind a generic callback layer.
+- Own permits, MultiMesh materialization, prototype Nodes or SceneTree roots.
+- Change material refresh version, rebuild rules, cache formats or visible output.
+
+## Paths
+
+- Exclusive: `src/render/m2/m2_mesh_resource_finalizer.gd`,
+  `src/tools/verify_m2_mesh_resource_finalizer.gd`,
+  `docs/modules/m2-mesh-resource-finalizer.md`, this claim
+- Shared: loader, Mesh pipeline/cache/extractor/runtime-finalizer/raw-repository/
+  prototype specs and verifiers, world renderer, registry, `RENDER.md`, M03 Evidence
+
+## Contracts and data
+
+- Pending requests are polled in existing Dictionary insertion order.
+- Empty Resource paths are discarded and marked missing immediately.
+- Only LOADED/FAILED statuses enter completion-order finalize FIFO.
+- One permit pops exactly one terminal record, including skipped/cached records.
+- Existing cached Mesh suppresses terminal Resource retrieval.
+- Loaded Resource uses exact first-Mesh extraction and current refresh-version path.
+- Raw M2 data loads only when the extracted Mesh is stale.
+- Prepared Mesh is stored by existing replacement semantics; failures mark missing.
+
+## Dependencies
+
+- Requires: accepted Mesh pipeline/cache/extractor/runtime finalizer/raw repository
+- Blocks: remaining loader-owned M2 materialization and orchestration cleanup
+
+## Verification
+
+- Synthetic polling/FIFO/skip/load/extract/refresh/store/missing/source/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
+- Next: implementation, verification and documentation
+- Blocked by:
