 ## Status
 
-- State: claimed
+- State: ready for integration
-- Done: all five loader-owned water pipeline collections and lifecycle sites identified
+- Done: pipeline state implemented; loader enqueue/start/publish/drain/release/
-- Next: implement state holder, migrate loader adapters, verify and document
+  reset/shutdown/metrics adapters migrated; required documentation added
+- Next: integrate and run post-merge smoke on master
 - Blocked by:
 
 ## Handoff
 
-- Commit:
+- Commit: `b7c036f`
-- Results:
+- Results: water pipeline PASS (`cases=12`, `iterations=100`,
-- Remaining risks:
+  `elapsed_ms=86.170`; initial direct cold run `94.576ms`); real Thread result
-- Documentation updated:
+  publication, FIFO/dedupe/task/cancel/clear/source contracts PASS; WMO caches/
+  queue/planner/registry/resolver, materials, shutdown and 18 adjacent M2/terrain/
+  facade/scheduler/streaming/coordinate regressions PASS; documentation and
+  coordination gates PASS; checkpoint dry-run PASS `7/7`.
+- Remaining risks: clear does not interrupt active WorkerThreadPool work and a
+  post-reset publication remains stale until drained/cleared, matching prior
+  behavior; payload Dictionaries require no mutation after publication; parser,
+  main-thread water materialization and asset-backed MH2O/MCLQ traversal/leak/
+  p95/p99/original-client evidence remain pending.
+- Documentation updated: inline public API; new
+  `docs/modules/adt-water-load-pipeline-state.md`; module registry, world renderer
+  and `RENDER.md`; data-flow/state/sequence/dependency diagrams, ownership,
+  threading, failure/recovery, profiles, performance limit and source map included.
