9 daysfix: code review cleanup — bugs, dead code, factorization (-167 lines)skal
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.
2026-02-28refactor(gpu): move SamplerCache impl to .cc, expose single entry pointskal
get_or_create() and clear() moved out of the header-only class. SamplerSpec and presets remain inline (trivial, no deps). handoff(Gemini): sampler_cache split into .h/.cc, sampler_cache.cc added to COMMON_GPU_EFFECTS. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-02-16refactor(headless): convert nullptr checks to strippable macrosskal
Added HEADLESS_RETURN_IF_NULL/HEADLESS_RETURN_VAL_IF_NULL macros that compile to no-ops in STRIP_ALL/FINAL_STRIP modes. Files updated: - fatal_error.h: New headless check macros - sequence.cc: NodeRegistry::create_texture - post_process_helper.cc: Pipeline creation functions - sampler_cache.h: SamplerCache::get_or_create - bind_group_builder.h: Layout/group builders - pipeline_builder.h: Shader and pipeline builders - All effect constructors (7 files) Headless tests passing. STRIP_ALL builds will have zero overhead. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
2026-02-16fix(headless): add nullptr checks for GPU resource creationskal
- NodeRegistry::create_texture: skip texture creation when device is nullptr - Post-process helpers: skip pipeline/bind group creation in headless mode - SamplerCache: return nullptr for headless mode - BindGroupLayoutBuilder/BindGroupBuilder: skip creation with null device - RenderPipelineBuilder: skip shader module and pipeline creation in headless - PlaceholderEffect: skip sampler creation in headless mode - RotatingCubeEffect: early return in constructor for headless mode WIP: Some effects (GaussianBlur, etc.) still need headless checks Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
2026-02-14style: Apply clang-format to codebaseskal
2026-02-11fix: Release cached samplers before WGPU shutdownskal
SamplerCache singleton never released samplers, causing device to retain references at shutdown. Add clear() method and call before fixture cleanup. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
2026-02-10refactor: Factor WGPU boilerplate into builder pattern helpersskal
Add BindGroupLayoutBuilder, BindGroupBuilder, RenderPipelineBuilder, and SamplerCache to reduce repetitive WGPU code. Refactor post_process_helper, cnn_effect, and rotating_cube_effect. Changes: - Bind group creation: 19 instances, 14→4 lines each - Pipeline creation: 30-50→8 lines - Sampler deduplication: 6 instances → cached - Total boilerplate reduction: -122 lines across 3 files Builder pattern prevents binding index errors and consolidates platform-specific #ifdef in fewer locations. Binary size unchanged (6.3M debug). Tests pass. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
