 ## Status
 
-- State: claimed
+- State: ready for integration
-- Done: rebuild predicate, one query site and two cache-clear sites identified
+- Done: classifier/cache implemented; loader query and both clear sites migrated;
-- Next: implement classifier, migrate loader adapter, verify and document
+  synthetic predicate/cache verifier and required documentation added
+- Next: integrate and run post-merge smoke on master
 - Blocked by:
 
 ## Handoff
 
-- Commit:
+- Commit: `19ca8f4`
-- Results:
+- Results: classifier PASS (`cases=12`, `iterations=100`,
-- Remaining risks:
+  `elapsed_ms=64.585`; initial `35.461ms`); billboard flag/count, invalid
-- Documentation updated:
+  variants/indices, UV rotation/speed/epsilon, four-stage cap, memoization,
+  detached diagnostics and clear contracts PASS; 33 M2/WMO/liquid/terrain/
+  facade/scheduler/streaming/coordinate/material/shutdown regressions PASS;
+  internal-access decreased to `35`; documentation and coordination gates PASS;
+  checkpoint dry-run PASS `7/7`.
+- Remaining risks: raw parser data remains Dictionary-based; the first decision
+  for a path remains authoritative until clear; classification covers the current
+  four-stage material implementation only; private asset descriptor-pressure,
+  traversal, p95/p99 and paired original-client evidence remain absent.
+- Documentation updated: inline public API; new
+  `docs/modules/m2-runtime-mesh-rebuild-classifier.md`; module registry, world
+  renderer and `RENDER.md`; data-flow/state/sequence/dependency diagrams,
+  ownership, failure/recovery, thresholds, cache lifetime and source map included.
