 ## Status
 
-- State: claimed
-- Done: four cache tables and all caller/lifecycle sites identified
-- Next: implement state service, migrate adapters, verify and document
+- State: ready
+- Done: cache state, loader/test adapters, lifecycle verifier and required documentation
+- Next: integrate and run post-merge acceptance
 - Blocked by:
 
 ## Handoff

-- Remaining risks:
-- Documentation updated:
+- Commit: `cd664eb`
+- Results: prototype state passes 16 admission/identity/negative/lifecycle/source
+  cases and 100-by-256 cycles in 50.266 ms; 46 autonomous headless verifiers
+  pass, while the proprietary ADT placement probe is unavailable without
+  `data/extracted`; checkpoint dry-run passes 7/7; documentation and
+  coordination gates pass; loader-private inventory decreases from 34 to 31.
+- Remaining risks: strong prototypes remain unbounded until shutdown; successful
+  asset traversal, descriptor pressure, leaks and p95/p99 require proprietary
+  data; no original-client visual comparison is claimed.
+- Documentation updated: inline API; `m2-prototype-cache-state.md` with data-flow,
+  lifecycle, sequence and dependency diagrams; pipeline/Mesh-cache/extractor/raw
+  repository/world-renderer specs, module registry and `RENDER.md`.
