+<!-- OPENWC_CLAIM:M03-RND-WMO-SCENE-INSTANCE-FACTORY-001:sindo-main-codex:2026-08-03 -->
+
+## Owner
+
+- Agent ID: `sindo-main-codex`
+- Target: M03 Renderer Facade and Safe Extraction
+- Branch: `work/sindo-main-codex/m03-wmo-scene-instance-factory`
+- Worktree: `C:\Users\sindo\open-wc-worktrees\m03-wmo-scene-instance-factory`
+
+## Outcome
+
+Move WMO cached-scene instantiation/currentness validation and live-prototype
+duplication with shared name/placement application into one main-thread factory.
+
+## Non-goals
+
+- Change cache lookup/admission, ResourceLoader or prototype construction.
+- Change runtime Mesh/material/occluder/shadow preparation.
+- Change attachment, placement registry, queues, permits or lifetime.
+- Change scene cache version rules or placement formulas.
+
+## Paths
+
+- Exclusive: `src/render/wmo/wmo_scene_instance_factory.gd`,
+  `src/tools/verify_wmo_scene_instance_factory.gd`,
+  `docs/modules/wmo-scene-instance-factory.md`, this claim
+- Shared: loader, adjacent WMO verifier/spec, renderer registry/specification,
+  `RENDER.md`, M03 Evidence
+
+## Contracts and data
+
+- Null scenes/prototypes and non-Node3D instantiation/duplication return null.
+- Cached instances failing the injected currentness validator are synchronously freed.
+- Accepted instances retain exact descendant Resource identities.
+- Both paths apply `relative_path.get_file().get_basename()` and the exact
+  placement-resolver Transform3D.
+- The factory returns detached roots and retains no Node or Resource.
+
+## Dependencies
+
+- Requires: accepted WMO placement resolver and runtime scene preparer
+- Blocks: remaining loader-owned WMO cache/prototype orchestration cleanup
+
+## Verification
+
+- Synthetic cached/live type, validation, freeing, exact identity, name,
+  transform, dependency/order, ownership, source and bounded-timing contracts;
+  adjacent WMO/renderer gates and checkpoint dry-run.
+
+## Documentation deliverables
+
+- Inline API docs; module API/I/O/ownership; data-flow/sequence/dependency
+  diagrams; adjacent renderer docs and M03 Evidence.
+
+## Status
+
+- State: active
+- Done: scope and contracts identified
+- Next: implement and verify factory delegation
+- Blocked by:
