+- Commits: implementation `b697a89`; cold-start fix `9408d88`
 - Results: `WorldRenderFacade` delegates loaded-mesh ground sampling and returns
   renderer-owned `RenderedGroundSample`; detached diagnostic snapshots preserve
   the probe report while hiding queue/tile/Mesh/Node references. Gameplay remains
   on the independent M02 `TerrainQuery` composition.
 - Verification: facade `delegation=5 ground_contract=2 runtime_scenes=2 tools=3`;
+  cold rendered-ground value `contract=3` from an empty Godot class cache;
   internal access `private_symbols=43 gameplay=7 editor_sources=9 renderer_tools=1`;
   terrain query contracts passed; coordinate boundary `files=113 consumers=5`;
   renderer manifest `7/7`; shutdown ownership, scheduler/planner, coordination,
