 ## Status
 
-- State: active
-- Done: worktree and bounded claim created
-- Next: implement facade, migrate runtime/tool consumers, document and verify
+- State: ready-for-review
+- Done: introduced the facade, migrated two runtime scenes and three renderer
+  tools, added regression coverage and updated renderer documentation
+- Next: M03 integrator reviews and merges `3d528e3`

+- Commit: `3d528e3`
+- Results: `WorldRenderFacade` is the runtime/tool surface for typed focus and
+  detached metrics; the existing streamer remains the sole owner of queues,
+  caches, tasks, nodes and RIDs.
+- Verification: facade `delegation=3 runtime_scenes=2 tools=3`; streaming focus
+  `contract=1 runtime_scenes=2 capture_tools=3`; coordinate boundary
+  `files=105 native_boundary=1 oracle=1 consumers=5 classifier_cases=6`;
+  render manifest `checkpoints=7 coverage=7 caches=7`; seven-checkpoint headless
+  dry-run; coordination/documentation/diff gates passed.
+- Fidelity: no changes to renderer target calculation, budgets, queue order,
+  cache versions, placement, visibility, materials or animation. The dry-run
+  retained all seven checkpoint plans. No build-12340 parity claim is added.
+- External/local inputs: ignored native DLL and generated ADT resource scripts
+  were copied from master only to run the worktree smoke. Proprietary extracted
+  ADT and character GLB data were unavailable, producing the expected dry-run
+  degraded-data diagnostics.
+- Remaining risks: environment, entity visuals and ground query are not yet
+  facade contracts; streamer exported configuration remains transitional scene
+  composition; focus-source sampling adds one small main-thread adapter step per
+  process frame while target refresh remains streamer-throttled.
+- Documentation updated: inline facade API, `docs/modules/world-renderer.md`
+  public API/inputs/outputs/data-flow/sequence/ownership/recovery/status/source
+  map, and `RENDER.md` file map plus implementation note.
