\ No newline at end of file +The `final` target is now part of the build system. What's next? +--- + +## Milestone Summary: Asset System & Production Pipeline (Jan 28, 2026) + +### Accomplishments: +1. **Refined Asset Management**: + * Refactored GetAsset to use an efficient O(1) array-based lookup. + * Decoupled generic manager logic (src/util/asset_manager.cc) from generated data. + * Established separate asset lists for demo and testing to prevent interference. +2. **Fully Automated Production Pipeline**: + * Integrated all steps into a single 'final' CMake target. + * Implemented scripts/gen_assets.sh for automatic spectrogram re-analysis. + * Optimized scripts/crunch_demo.sh for macOS stripping and compression (gzexe). +3. **Visual Improvements**: + * Added rotation, color shifting, and brightness boosts synchronized with audio peaks. + * Implemented background flash effect on beats. +4. **Stability & Quality**: + * Applied mandatory descriptive headers to all source files. + * Fixed various build system edge cases (e.g., target file resolution, stripped build dependencies). + * Ensured all tests (AssetManager, Synth, Spectool, Window) pass. + +### Status: +* The demo now features a working sequencer with embedded drum samples. +* Final compressed binary size on macOS is approximately 107KB (with assets). +* The project is ready for the next phase of development (cross-compilation or advanced compression). |
