-## Future: CNN v3 8-bit Quantization
+## Future: CNN v3 — U-Net + FiLM
+
+U-Net architecture with FiLM conditioning. Runtime style control via beat/audio.
+Richer G-buffer input (normals, depth, material IDs). Per-pixel testability across
+PyTorch / HTML WebGPU / C++ WebGPU.
+
+**Prerequisites:** G-buffer implementation (GEOM_BUFFER.md)
+**Design:** `cnn_v3/docs/CNN_V3.md`
+
+**Phases:**
+1. G-buffer prerequisite
+2. Training infrastructure (Blender exporter + photo pipeline)
+3. WGSL shaders (enc/dec/bottleneck, deterministic ops)
+4. C++ effect class + FiLM uniform upload
+5. Parity validation (test vectors, ≤1/255 per pixel)
+
+## Future: CNN v2 8-bit Quantization
 
 Reduce weights from f16 (~3.2 KB) to i8 (~1.6 KB).
