fix: code review cleanup — bugs, dead code, factorization (-167 lines)

2026-05-20T20:44:44Z

Bugs: - B1: fix dead tempo debug (prev_tempo captured after assignment) - B2: fix ReloadAssetsFromFile leak for disk-loaded assets; simplify DropAsset - B3: fix get_free_pool_slot leak (unregister synth + free data on reuse) - B4: volatile -> std::atomic with acquire/release in miniaudio_backend, synth - B5: fix unaligned reads in scene_loader (memcpy-based read_f32/read_u32) - B6: fix shader module + BGL + pipeline layout leaks in gpu.cc, pipeline_builder Dead code: - D1: remove unused particle_defs.h - D3: remove create_post_process_pipeline_simple (zero callers) - D4: remove empty gpu_draw() - D5: remove write-only Hybrid3D::initialized_ - D6: remove legacy pending buffer path in audio.cc Factorization: - F1: Effect::run_fullscreen_pass() replaces boilerplate in 5 effects - F2: particle_common.wgsl snippet, #include in 3 WGSL shaders - F3: gpu_create_shader_module() helper, used in 3 call sites - F5: get_world_aabb() shared between bvh.cc and physics.cc - F6: samples_to_seconds() replaces 6 inline expressions - F7: gpu_create_linear/nearest_sampler use SamplerCache; add nearest() preset 37/37 tests passing. handoff(Claude): code review batch — all items verified, no regressions.

fix(cnn_v3): remove dec0 ReLU, load FiLM MLP at runtime

2026-03-27T06:59:00Z

Two bugs blocking training convergence: 1. dec0 ReLU before sigmoid constrained output to [0.5,1.0] — network could never produce dark pixels. Removed F.relu in train_cnn_v3.py and max(0,…) in cnn_v3_dec0.wgsl. Test vectors regenerated. 2. set_film_params() used hardcoded heuristics instead of the trained MLP. Added CNNv3FilmMlp struct + load_film_mlp() to cnn_v3_effect.h/.cc. MLP auto-loaded from ASSET_WEIGHTS_CNN_V3_FILM_MLP at construction; Linear(5→16)→ReLU→Linear(16→72) runs CPU-side each frame. 36/36 tests pass. Parity max_err=4.88e-4 unchanged. handoff(Gemini): retrain from scratch — needs ≥50 samples (currently 11). See cnn_v3/docs/HOWTO.md §2-3.

feat(cnn_v3): upgrade architecture to enc_channels=[8,16]

2026-03-26T06:03:01Z

Double encoder capacity: enc0 4→8ch, enc1 8→16ch, bottleneck 16→16ch, dec1 32→8ch, dec0 16→4ch. Total weights 2476→7828 f16 (~15.3 KB). FiLM MLP output 40→72 params (L1: 16×40→16×72). 16-ch textures split into _lo/_hi rgba32uint pairs (enc1, bottleneck). enc0 and dec1 textures changed from rgba16float to rgba32uint (8ch). GBUF_RGBA32UINT node gains CopySrc for parity test readback. - WGSL shaders: all 5 passes rewritten for new channel counts - C++ CNNv3Effect: new weight offsets/sizes, 8ch uniform structs - Web tool (shaders.js + tester.js): matching texture formats and bindings - Parity test: readback_rgba32uint_8ch helper, updated vector counts - Training scripts: default enc_channels=[8,16], updated docstrings - Docs + architecture PNG regenerated handoff(Gemini): CNN v3 [8,16] upgrade complete. All code, tests, web tool, training scripts, and docs updated. Next: run training pass.

fix(cnn_v3_debug): add CNNv3Effect to debug sequence for prev.r/g/b temporal feedback

2026-03-23T07:05:12Z

timeline.seq is the canonical source — timeline.cc was wrongly hand-edited. Add CNNv3Effect + cnn_out (gbuf_albedo) node to cnn_v3_debug sequence so wire_dag() can wire GBufferEffect.cnn_output_node_ correctly. Also fix node_prev_tex_ NodeType: F16X8 (Rgba16Float+CopyDst) to match CNNv3Effect output format (GBUF_ALBEDO = Rgba16Float). Regenerated timeline.cc via: python3 tools/seq_compiler.py workspaces/main/timeline.seq Co-Authored-By: Claude Sonnet 4.6

fix(cnn_v3): shadow pass — 5 bugs fixed, labels in gbuf_view

2026-03-22T22:17:50Z

1. Camera Y-inversion: proj.m[5] = -proj.m[5] in upload_scene_data + WGPUFrontFace_CCW on raster pipeline. 2. Shadow formula: replace shadowWithStoredDistance with 64-step IQ soft shadow (8*d/t, unbounded). 3. Local→world SDF scale: d *= length(obj.model[0].xyz). 4. Shadow bias: use rasterized normal from normal_mat_tex (binding 4) instead of light direction — fixes terminator self-shadow on spheres. 5. ShaderComposer: GBufViewEffect now resolves #include via ShaderComposer::Get().Compose(). Also: per-tile channel labels in gbuf_view.wgsl via debug_str. Scene simplified to 1 cube + 1 sphere for debugging (restore TODO). Scale propagation for pulsating sphere confirmed correct end-to-end. handoff(Gemini): shadow validated. Next: restore full scene in GBufferEffect::set_scene() (20 cubes + 4 spheres, 2 lights), then run training pass per cnn_v3/docs/HOWTO.md §3.
