+## Priority 2: CNN v2 - Parametric Static Features (Task #85) [PLANNING]
+
+Enhanced CNN post-processing with multi-dimensional feature inputs.
+
+**Design:** `doc/CNN_V2.md`
+
+**Implementation phases:**
+1. Static features compute shader (RGBD + UV + sin encoding + bias)
+2. C++ effect class (multi-pass layer execution)
+3. Training pipeline (PyTorch f32 → f16 export)
+4. Validation tooling (end-to-end checkpoint testing)
+
+**Key improvements over v1:**
+- 7D static feature input (vs 4D RGB)
+- Per-layer configurable kernels (1×1, 3×3, 5×5)
+- Float16 weight storage (~6.4 KB vs 3.2 KB)
+
+**Target:** <10 KB for 64k demo constraint
