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.

refactor(shaders): extract oct-normal encode/decode into math/normal snippet

2026-03-22T19:10:53Z

New src/shaders/math/normal.wgsl: oct_encode, oct_decode, oct_encode_unorm, oct_decode_unorm. Registered in InitShaderComposer as "math/normal". Removed inline copies from gbuf_raster.wgsl and gbuf_pack.wgsl. 18/18 tests passing.

fix(effects): particle sync and heptagon SDF bugs

2026-03-10T22:04:13Z

- particles: stagger respawn y by golden-ratio index offset to break per-row synchronization (100 particles per row fell in lock-step) - heptagon: fix swapped atan2(x,y)->atan2(y,x) and WGSL % truncation for negative angles (broke SDF for entire lower half of shape) handoff(Gemini): heptagon now correct; particles desynchronized Co-Authored-By: Claude Sonnet 4.6

ntsc: factor common code into snippet; add RGB and YIQ input variants

2026-03-10T19:42:32Z

- Extract shared NTSC logic into render/ntsc_common.wgsl snippet - sample_ntsc_signal() hook decouples input format from processing - ntsc_rgb.wgsl: RGB input (converts via rgba_to_luma_chroma_phase) - ntsc_yiq.wgsl: YIQ passthrough for RotatingCube output - Add NtscYiq WgslEffect thin wrapper; register both in tests handoff(Claude): NTSC refactor complete; NtscYiq ready for timeline use with RotatingCube.
