+## 2026-07-17 ADT Water Load Pipeline State Extraction
+
+- `AdtWaterLoadPipelineState` now owns ADT water pending FIFO/deduplication,
+  active WorkerThreadPool task IDs and the mutex-protected parsed-result mailbox.
+- `StreamingWorldLoader` still selects concurrency, starts/waits tasks, invokes
+  `ADTLoader`, consumes `WATER_FINALIZE` permits, rejects stale tile/path/root
+  results and builds/attaches water Nodes through `ADTBuilder` on the main thread.
+- Tile release still cancels only pending water requests; active work completes
+  and its result is discarded when tile ownership is stale. Shutdown waits task
+  IDs before clearing state; reset does not interrupt workers.
+- Pending-plus-active `water` metrics, parsing, formats, materials, profiles and
+  visible behavior are unchanged.
+- Asset-backed MH2O/MCLQ fidelity, long-traversal leak/p95/p99 and paired capture
+  evidence remain pending.
