Replaces CNNv3Effect in cnn_v3_test sequence until training is complete. 37/37 tests passing. handoff(Gemini): GBufDeferredEffect wired in timeline; CNN v3 pipeline: GBufferEffect → GBufDeferredEffect → sink. 2026-03-22T18:29:01Z skal pascal.massimino@gmail.com 2026-03-22T18:29:01Z urn:sha1:7b89a7130a998017de98dde363a8d9be61d7d44e Implements gbuf_shadow.wgsl: fullscreen render pass that reads depth from Pass 1, reconstructs world-space positions, evaluates a proxy-box SDF for each object (via inv_model), computes soft shadows for both directional lights using shadowWithStoredDistance(), and writes shadow factor to the RGBA8Unorm node_shadow_ target consumed by gbuf_pack.wgsl. Bind layout: B0=GlobalUniforms, B1=ObjectsBuffer (storage-read), B2=texture_depth_2d, B3=GBufLightsUniforms. Sky fragments (depth=1.0) are output as 1.0 (fully lit). Falls back to clear(1.0) if pipeline is not ready. 36/36 tests pass. handoff(Gemini): Pass 2 done. Pass 3 (transparency) still TODO. Phase 4 (type-aware SDF) optional after visual validation. 2026-03-22T15:21:25Z skal pascal.massimino@gmail.com 2026-03-22T15:21:25Z urn:sha1:159ca2ca19345515cdfebed9fd88646730492cd2 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.
