21 hours	refactor: Deduplicate CommonUniforms with #include in WGSL shaders	skal
	Replace redundant CommonUniforms struct definitions across 13 shaders with #include "common_uniforms" directive. Integrate ShaderComposer preprocessing into all shader creation pipelines. Changes: - Replace 9-line CommonUniforms definitions with single #include line - Add ShaderComposer.Compose() to create_post_process_pipeline() - Add ShaderComposer.Compose() to gpu_create_render_pass() - Add ShaderComposer.Compose() to gpu_create_compute_pass() - Add InitShaderComposer() calls to test_effect_base and test_demo_effects - Update test_shader_compilation to compose shaders before validation Net reduction: 83 lines of duplicate code eliminated All 35 tests passing (100%) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
27 hours	fix: Resolve WebGPU uniform buffer alignment issues (Task #74)	skal
	Fixed critical validation errors caused by WGSL vec3<f32> alignment mismatches. Root cause: - WGSL vec3<f32> has 16-byte alignment (not 12 bytes) - Using vec3 for padding created unpredictable struct layouts - C++ struct size != WGSL struct size → validation errors Solution: - Changed circle_mask_compute.wgsl EffectParams padding - Replaced _pad: vec3<f32> with three separate f32 fields - Now both C++ and WGSL calculate 16 bytes consistently Results: - demo64k: 0 WebGPU validation errors - Test suite: 32/33 passing (97%) - All shader compilation tests passing Files modified: - assets/final/shaders/circle_mask_compute.wgsl - TODO.md (updated task status) - PROJECT_CONTEXT.md (updated test results) - HANDOFF_2026-02-09_UniformAlignment.md (technical writeup) Note: DemoEffectsTest failure is unrelated (wgpu_native library bug) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
38 hours	feat(shaders): Standardize all shaders to use CommonUniforms	skal
	Define CommonUniforms struct with standard fields: - resolution: vec2<f32> - aspect_ratio: f32 - time: f32 - beat: f32 - audio_intensity: f32 Updated 14 shaders to use CommonUniforms: - Replaced width/height with resolution - Unified intensity/audio_peak → audio_intensity - Moved effect-specific params to EffectParams struct - visual_debug.wgsl now uses GlobalUniforms.view_proj All shaders now have consistent uniform interface.

6 days	feat: Optional sequence end times and comprehensive effect documentation	skal
	This milestone implements several key enhancements to the sequencing system and developer documentation: ## Optional Sequence End Times (New Feature) - Added support for explicit sequence termination via [time] syntax - Example: SEQUENCE 0 0 [30.0] forcefully ends all effects at 30 seconds - Updated seq_compiler.cc to parse optional [time] parameter with brackets - Added end_time_ field to Sequence class (default -1.0 = no explicit end) - Modified update_active_list() to check sequence end time and deactivate all effects when reached - Fully backward compatible - existing sequences work unchanged ## Comprehensive Effect Documentation (demo.seq) - Documented all effect constructor parameters (standard: device, queue, format) - Added runtime parameter documentation (time, beat, intensity, aspect_ratio) - Created detailed effect catalog with specific behaviors: * Scene effects: HeptagonEffect, ParticlesEffect, Hybrid3DEffect, FlashCubeEffect * Post-process effects: GaussianBlurEffect, SolarizeEffect, ChromaAberrationEffect, ThemeModulationEffect, FadeEffect, FlashEffect - Added examples section showing common usage patterns - Documented exact parameter behaviors (e.g., blur pulsates 0.5x-2.5x, flash triggers at intensity > 0.7, theme cycles every 8 seconds) ## Code Quality & Verification - Audited all hardcoded 1280x720 dimensions throughout codebase - Verified all shaders use uniforms.resolution and uniforms.aspect_ratio - Confirmed Effect::resize() properly updates width_/height_ members - No issues found - dimension handling is fully dynamic and robust ## Files Changed - tools/seq_compiler.cc: Parse [end_time], generate set_end_time() calls - src/gpu/effect.h: Added end_time_, set_end_time(), get_end_time() - src/gpu/effect.cc: Check sequence end time in update_active_list() - assets/demo.seq: Comprehensive syntax and effect documentation - Generated files updated (timeline.cc, assets_data.cc, music_data.cc) This work establishes a more flexible sequencing system and provides developers with clear documentation for authoring demo timelines. handoff(Claude): Optional sequence end times implemented, effect documentation complete, dimension handling verified. Ready for next phase of development.
7 days	refactor: Shader Asset Integration (Task #24)	skal
	Extracted all hardcoded WGSL shaders into external assets. Updated AssetManager to handle shader snippets. Refactored Renderer3D, VisualDebug, and Effects to load shaders via the AssetManager, enabling better shader management and composition.
