10 hours	feat(assets): Add dodecahedron mesh asset	skal
	Added dodecahedron.obj (downloaded from external source) to demo assets. Updated test_3d_render to display the dodecahedron mesh alongside the cube mesh. Verified asset packing and rendering pipeline.
11 hours	feat(3d): Implement basic OBJ mesh asset pipeline	skal
	Added support for loading and rendering OBJ meshes. - Updated asset_packer to parse .obj files into a binary format. - Added MeshAsset and GetMeshAsset helper to asset_manager. - Extended Object3D with mesh_asset_id and ObjectType::MESH. - Implemented mesh rasterization pipeline in Renderer3D. - Added a sample cube mesh and verified in test_3d_render.
15 hours	refactor(gpu): Implement compile-time BVH toggle via shader composition	skal
	Completed Task #18-B optimization and refactoring. - Replaced runtime branching in shader with compile-time snippet substitution in ShaderComposer. - Added 'scene_query_bvh.wgsl' and 'scene_query_linear.wgsl' as distinct snippets. - Refactored Renderer3D to manage two separate pipelines (with and without BVH). - Updated ShaderComposer to support snippet substitution during composition. - Verified both paths with test_3d_render (default and --no-bvh). - Removed temporary shader hacks and cleaned up renderer_3d.wgsl.
2 days	feat(gpu): Implement recursive WGSL composition and modularize shaders (Task ↵	skal
	#50) - Updated ShaderComposer to support recursive #include "snippet_name" with cycle detection. - Extracted granular WGSL snippets: math/sdf_shapes, math/sdf_utils, render/shadows, render/scene_query, render/lighting_utils. - Refactored Renderer3D to use #include in shaders, simplifying C++ dependency lists. - Fixed WGPUShaderSourceWGSL usage on macOS to correctly handle composed shader strings. - Added comprehensive unit tests for recursive composition in test_shader_composer. - Verified system stability with test_3d_render and full test suite. - Marked Task #50 as recurrent for future code hygiene.
3 days	fix: Implement proper skybox rendering with Perlin noise	skal
	- Added ObjectType::SKYBOX for dedicated skybox rendering. - Created assets/final/shaders/skybox.wgsl for background rendering. - Implemented a two-pass rendering strategy in Renderer3D::render: - First pass renders the skybox without depth writes. - Second pass renders scene objects with depth testing. - Corrected GlobalUniforms struct in common_uniforms.wgsl and src/3d/renderer.h to include and explicit padding for 112-byte alignment. - Updated Renderer3D::update_uniforms to set the new and zero-initialize padding. - Reverted sky sampling logic in renderer_3d.wgsl to for SDF misses, preventing background bleed-through. - Updated test_3d_render.cc to include a SKYBOX object with Perlin noise. handoff(Gemini): The skybox is now correctly rendered with Perlin noise as a dedicated background pass. Objects render correctly without transparency to the sky. All necessary C++ and WGSL shader changes are implemented and verified.
3 days	feat(assets): Add new drum samples and improve conversion script	skal
	Created a new script, scripts/gen_spectrograms.sh, to robustly convert all audio files in assets/originals to .spec format. The new script is more portable and provides better feedback. Added the newly generated drum and bass samples to the asset list, organizing them by type for clarity. This completes the requested sub-task.
3 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.
5 days	feat(gpu): Integrate bumpy 3D renderer into main demo	skal
	- Added depth buffer support to MainSequence. - Implemented Hybrid3DEffect for the main timeline. - Fixed effect initialization order in MainSequence. - Ensured depth-stencil compatibility for all scene effects. - Updated demo sequence with 3D elements and post-processing.
5 days	feat(assets): Implement procedural asset generation pipeline	skal
	- Updated asset_packer to parse PROC(...) syntax with robust regex. - Implemented runtime dispatch in AssetManager for procedural generation. - Added procedural generator functions (noise, grid, periodic). - Added comprehensive tests for procedural asset lifecycle.
9 days	chore(assets): Clean up demo_assets.txt	skal
	Removed dummy and test assets from the main demo list, leaving only the required drum samples.
9 days	feat(assets): Separate demo and test asset lists	skal
	Renamed demo assets to 'demo_assets.txt' and created 'test_assets_list.txt' for AssetManagerTest to prevent interference. - Updated CMakeLists.txt to generate separate headers for demo and test. - Updated test_assets.cc to conditionally include the test-specific header. - Incorporated gen_assets.sh into the 'final' target.
