 ## Handoff
 
-- Commit:
-- Results:
-- Remaining risks:
-- Documentation updated:
+- Commit: `7779e9e` (`render: extract WMO scene resource finalizer`)
+- Results: finalizer PASS `cases=26 iterations=1000 elapsed_ms=4.186`;
+  adjacent WMO scene/render cache/finalizer/queue/planner/registry/resolver and
+  shutdown checks passed; autonomous headless suite `61/61`; documentation `48`;
+  coordination passed with `34` historical warnings; checkpoint dry-run `7/7`.
+- Remaining risks: PackedScene probe validation remains synchronous main-thread
+  work; no serialized private WMO stale/oversize, long leak, visual,
+  descriptor-pressure or p95/p99 evidence was added.
+- Documentation updated: new full module specification with API/I/O and
+  data-flow/state/sequence/dependency diagrams; adjacent WMO cache/world-renderer
+  specs, module registry, `RENDER.md` and M03 Evidence.
