3D World Foundation — Phase 1R-C (governed place authoring)

Phase 1R visual qualification

• P1Tree cannot be authored inside water (validation fails)
• P2Planting bed cannot intersect the stream
• P3Playable/open ground explicitly reserved
• P4All placement obeys semantic zones + exclusions
• P5A deliberately invalid fixture is rejected
• P6Blender consumes validated truth (no layout decisions)
• P7Three consumes compiled output (no logic from meshes)
• P8More credible than the rejected unconstrained scene
• P9Founder never touches Blender
• P10Build green; runtime lazy-loaded (no 3D on initial load)

Phase 1R-C: place truth → constraint validation → Blender compilation → runtime. Impossible placements (e.g. tree-in-river) are rejected by construction; a deliberately invalid fixture is proven rejected. Character omitted. Highest automated status is GOVERNED PLACE AUTHORING PASSED — FOUNDER VISUAL REVIEW REQUIRED.
