Phase N.4 (Rendering Pipeline Foundation) ships. WbFoundationFlag flips to default-on (== "1" → != "0"). WB's ObjectMeshManager is now acdream's production mesh pipeline; WbDrawDispatcher is the production draw path. Legacy InstancedMeshRenderer is retained as ACDREAM_USE_WB_FOUNDATION=0 escape hatch until N.6 retires it. Visual verification at Holtburg passed: - Scenery (trees / rocks / fences / buildings) renders correctly - Characters connected with full close-detail geometry (Issue #47 preserved — GfxObjDegradeResolver path intact) - FPS substantially improved by grouped instanced draws + per-entity AABB cull + opaque front-to-back sort + palette-hash memoization Three high-value WB API gotchas surfaced during Task 26 visual verification and are now documented in CLAUDE.md "WB integration cribs" + plan Adjustments 7-9 + memory project_phase_n4_state.md: 1. ObjectMeshManager.IncrementRefCount only bumps a counter — does NOT trigger mesh loading. Call PrepareMeshDataAsync explicitly. 2. ObjectRenderBatch.SurfaceId is unset — read batch.Key.SurfaceId. 3. Modern rendering (GL 4.3 + bindless = every modern GPU) packs every mesh into ONE global VAO/VBO/IBO. Use glDrawElementsInstancedBaseVertex(BaseInstance) with FirstIndex + BaseVertex from the batch, not naive DrawElementsInstanced. Plan doc flipped to Final state. Roadmap N.4 → Live ✓; N.5 rebranded from "Terrain rendering" to "Modern rendering path" (bindless + multi-draw indirect on top of N.4's foundation; terrain rendering moves to N.5b). CLAUDE.md "Currently in flight" pointer updated to N.5. New memory file project_phase_n4_state.md preserves the three WB gotchas for cross-session continuity. n4-verify*.log added to .gitignore.
