feat(cnn_v3): add G-buffer visualizer + web sample loader (Phase 7)
C++ GBufViewEffect: renders all 20 feature channels from feat_tex0/feat_tex1
in a 4×5 tiled grid. Custom BGL with WGPUTextureSampleType_Uint; bind group
rebuilt per frame via wgpuRenderPipelineGetBindGroupLayout.
Web tool: "Load sample directory" button — webkitdirectory picker, FULL_PACK_SHADER
compute (matches gbuf_pack.wgsl packing), runFromFeat() skips photo-pack step,
computePSNR() readback + comparison vs target.png side-by-side.
36/36 tests pass. Docs updated: HOWTO.md §9, README, PROJECT_CONTEXT, TODO,
COMPLETED.
handoff(Gemini): CNN v3 Phase 7 done. Next: run train_cnn_v3.py (see HOWTO §3).

See `doc/archive/` for detailed historical documents. ## March 2026 +- [x] **CNN v3 Phase 7: Validation tools** — `GBufViewEffect` (C++ 4×5 channel grid, `cnn_v3/shaders/gbuf_view.wgsl`, `cnn_v3/src/gbuf_view_effect.{h,cc}`): renders all 20 G-buffer feature channels tiled on screen; custom BGL with `WGPUTextureSampleType_Uint`, bind group rebuilt per frame via `wgpuRenderPipelineGetBindGroupLayout`. Web tool "Load sample directory" (`cnn_v3/tools/tester.js` + `shaders.js`): `webkitdirectory` picker, `FULL_PACK_SHADER` compute (matches `gbuf_pack.wgsl`), `runFromFeat()` inference, PSNR vs `target.png`. 36/36 tests. + - [x] **CNN v3 Phase 5: Parity validation** — `test_cnn_v3_parity.cc` (2 tests: zero_weights, random_weights). Root cause: intermediate nodes declared at full res instead of W/2, W/4. Fix: `NodeRegistry::default_width()/default_height()` getters + fractional resolution in `declare_nodes()`. Final max_err=4.88e-4 ✓. 36/36 tests. - [x] **CNN v3 Phase 4: C++ CNNv3Effect + FiLM uniform upload** — `cnn_v3/src/cnn_v3_effect.{h,cc}`. 5 compute passes (enc0→enc1→bottleneck→dec1→dec0), shared f16 weights buffer, per-pass uniform buffers, `set_film_params()` API. Key fix: WGSL `vec3u` has align=16, so `CnnV3Params4ch`=64B and `CnnV3ParamsEnc1`=96B (not 48/80). Weight offsets as explicit formulas. FiLM γ/β identity defaults; real values await `train_cnn_v3.py`. 35/35 tests. |
