 ## Handoff
 
-- Commit:
-- Results:
-- Remaining risks:
-- Documentation updated:
+- Commit: `ae40e3f` (`render: extract WMO runtime Mesh finalizer`)
+- Results: finalizer PASS `cases=27 iterations=1000 elapsed_ms=0.402` in the
+  full run; autonomous headless suite `63/63`; documentation `49`; coordination
+  passed with `34` historical warnings; checkpoint dry-run `7/7`.
+- Remaining risks: WMOBuilder surface mutation remains synchronous main-thread
+  work; no private WMO corpus, visual comparison, leak/GPU or p95/p99 evidence.
+- Documentation updated: new full module specification with API/I/O and
+  data-flow/state/sequence/dependency diagrams; renderer registry/source map,
+  `RENDER.md` and M03 Evidence.
