+- Commit: `1807c3a`
+- Results: facade now exposes idempotent `present_entity`, explicit
+  `remove_entity` and detached diagnostics. Both runtime scenes compose a
+  `WorldEntityPresenter` that owns one replaceable visual subtree per valid
+  session `EntityId`; local player and authoritative state remain separate.
+- Verification: entity `snapshot_cases=8 lifecycle_cases=14 runtime_scenes=2`;
+  facade `delegation=9 entity_contract=6`; identities `5/5/6/5`; character
+  presentation `9/10/3/1`; coordinate boundary `files=119`; internal access
+  `43/7/9/1`; environment/ground/terrain, manifest `7/7`, shutdown, scheduler
+  (`20000` iterations), planner (`250` iterations), focus, editor parse, dry-run,
+  coordination, documentation and diff gates passed.
+- Fidelity: runtime produces no world-entity commands yet, so all seven baseline
+  plans and existing player/world output remain unchanged. No build-12340
+  display, equipment, animation, effects or visibility parity claim is added.
+- External/local inputs: ignored native DLL and generated ADT scripts supported
+  editor/dry-run only. Missing proprietary ADT/DBC/character corpus produced the
+  expected degraded diagnostics.
+- Remaining risks: PackedScene create/replace loads synchronously and is not an
+  accepted network-scale hot path; resource paths are adapter inputs rather than
+  stable content IDs; animation/equipment/effects and scale profiling remain open.
+- Documentation updated: new world-entity-presentation API/input-output/data-flow/
+  lifecycle/sequence/ownership/failure/configuration/migration/diagnostic/source-map
+  spec; world renderer, module registry and `RENDER.md` updated.
