 ## Status
 
-- State: claimed
-- Done: scope and state transitions identified
-- Next: implement state holder, migrate loader adapters, verify and document
+- State: ready for integration
+- Done: state holder implemented; loader cache/request/reset/metrics adapters
+  migrated; shutdown regression and required documentation updated
+- Next: integrate and run post-merge smoke on master

 ## Handoff
 
-- Commit:
-- Results:
-- Remaining risks:
-- Documentation updated:
+- Commit: `d39f591`
+- Results: cache-state PASS (`cases=10`, `iterations=100`,
+  `elapsed_ms=58.727`); direct no-`.godot` cache-state run PASS (`45.361ms`);
+  WMO queue/planner/registry/resolver/material/shutdown plus 18 adjacent
+  M2/terrain/facade/scheduler/streaming/coordinate regressions PASS;
+  documentation and coordination gates PASS; checkpoint dry-run PASS `7/7`.
+- Remaining risks: accepted Resources remain strongly referenced until full
+  shutdown release; cached-scene and ResourceLoader I/O seams remain in loader;
+  no proprietary corrupt-cache fixture, asset-backed WMO traversal/leak run,
+  p95/p99 or original-client paired evidence. Full loader cannot be used as a
+  direct empty-class-cache smoke because pre-existing typed global coordinate/
+  focus dependencies require editor class registration; the extracted service
+  itself passed cold and normal editor parse passed.
+- Documentation updated: inline public API; new
+  `docs/modules/wmo-render-resource-cache-state.md`; module registry, WMO queue,
+  world renderer and `RENDER.md`; data-flow/state/sequence diagrams, ownership,
+  threading, cache-version boundary, failure/recovery and source map included.
