-- Documentation updated:
+- Commit: `c590036`
+- Results: `verify_wmo_placement_registry.gd` PASS cases=10,
+  iterations=100, elapsed_ms=53.941; 21 adjacent WMO/M2/terrain/facade/
+  scheduler/streaming/coordinate regressions PASS; documentation and
+  coordination gates PASS; render dry-run PASS 7/7.
+- Remaining risks: no proprietary asset corpus or original-client paired WMO
+  capture; dry-run reports expected missing ADT/DBC/character assets; WMO
+  build/resource state remains loader-owned.
+- Documentation updated: `docs/modules/wmo-placement-registry.md`,
+  `docs/modules/wmo-placement-resolver.md`, `docs/modules/world-renderer.md`,
+  `docs/modules/README.md`, `RENDER.md`; inline public API comments added.
