This commit introduces a dual-mode asset loading system to enhance developer workflow and optimize release builds.
Key changes include:
- **Dual-Mode Asset Loading:** Assets are now loaded from disk during development (when is OFF) for faster iteration, particularly for heavy assets like and files. For release builds ( ON), all assets are embedded directly into the binary, ensuring a single, self-contained executable.
- **Explicit Asset Typing:** Replaced generic asset type with specific types (, , , , ) in and the enum in for clearer categorization and more robust processing.
- **Build System Integration:** Modified to pass a flag to in development builds.
- **Asset Packer Updates:** now generates file paths for disk-loaded assets and embeds data for others based on the build mode.
- **Asset Manager Enhancements:** includes new logic in for loading and caching disk-based assets and updates to for proper memory deallocation.
- **Documentation:** Updated to reflect the new asset nomenclature and dual-mode loading strategy.
- **Project Rules:** Added a concise rule to mandating top-level documentation updates for medium/large sub-system changes.
handoff(Gemini): Implemented dual-mode asset loading and updated documentation.

enum, add MP3 type
- Add AssetType enum {STATIC, PROC, PROC_GPU, MP3} to AssetRecord
- Add GetAssetType() API to asset_manager.h/cc
- asset_packer: parse 'MP3' compression keyword in assets.txt
- tracker: remove magic-byte is_mp3_asset(); use GetAssetType() instead
- assets.txt: NEVER_MP3 now uses 'MP3' compression type
- doc/ASSET_SYSTEM.md: rewritten to document new types and API
handoff(Gemini): AssetType enum landed; MP3 detection is now explicit via asset metadata.

Update all doc references from old paths to workspace structure:
- assets/demo.seq → workspaces/main/timeline.seq
- assets/music.track → workspaces/main/music.track
- assets/final/demo_assets.txt → workspaces/main/assets.txt
- assets/test_demo.* → workspaces/test/*
Files updated:
- HOWTO.md: Add workspace selection, update paths
- SEQUENCE.md: Update examples and integration
- ASSET_SYSTEM.md: Workspace-aware workflow
- CONTRIBUTING.md: Workspace timeline paths
- ARCHITECTURE.md: Generic workspace reference

- HOWTO.md: 184→97 lines (quick reference only)
- BUILD.md: Add build modes, header organization, dependency tracking
- ASSET_SYSTEM.md: Add developer workflow section
- TRACKER.md: Add AudioEngine API documentation
Net: -147 lines in HOWTO.md
|

Consolidated and streamlined all documentation:
**Merged:**
- PROCEDURAL.md → deleted (content in ASSET_SYSTEM.md)
- FETCH_DEPS.md → BUILD.md (dependencies section)
**Simplified (line reductions):**
- HOWTO.md: 468→219 (53%)
- CONTRIBUTING.md: 453→173 (62%)
- SPECTRAL_BRUSH_EDITOR.md: 497→195 (61%)
- SEQUENCE.md: 355→197 (45%)
- CONTEXT_MAINTENANCE.md: 332→200 (40%)
- test_demo_README.md: 273→122 (55%)
- ASSET_SYSTEM.md: 271→108 (60%)
- MASKING_SYSTEM.md: 240→125 (48%)
- 3D.md: 196→118 (40%)
- TRACKER.md: 124→76 (39%)
- SCENE_FORMAT.md: 59→49 (17%)
- BUILD.md: 83→69 (17%)
**Total:** 3344→1657 lines (50.4% reduction)
**Changes:**
- Removed verbose examples, redundant explanations, unimplemented features
- Moved detailed task plans to TODO.md (single source of truth)
- Consolidated coding style rules
- Kept essential APIs, syntax references, technical details
**PROJECT_CONTEXT.md:**
- Added "Design Docs Quick Reference" with 2-3 line summaries
- Removed duplicate task entries
- All design docs now loaded on-demand via Read tool
Result: Context memory files reduced from 31.6k to ~15k tokens.

Assigned reference numbers to all remaining tasks in documentation:
- Task #34: Full STL Removal
- Task #35: CRT Replacement
- Task #36: Blender Exporter
- Task #37: Asset Ingestion
- Task #38: Runtime Loader
- Task #39: Visual Debugging System
- Task #40: Advanced Lighting & Transparency
- Task #41: Spectrogram Editor HTML Tool
- Task #42: Vectorial Spectrogram Reader (C++)
- Task #43: Spectrogram Drawing Bricks
Ensured consistent task numbering across PROJECT_CONTEXT.md and TODO.md.

Lowered the priority of the 'replace STL' task. It will be addressed in the final optimization phase (Phase 2) to simplify current development. Hot paths in AssetManager and Procedural remain optimized.
handoff(Gemini): STL usage is now permitted for non-critical paths until the final optimization phase. PROJECT_CONTEXT.md and TODO.md updated accordingly.

Critical Bug Fixes:
- Fixed pool exhaustion: Tracker slots never freed after use, music stopped
after 8 patterns. Implemented round-robin allocation with cleanup.
- Fixed note name parsing: Added automatic note-to-frequency conversion
in tracker_compiler. Bass and melody now play correctly.
- Fixed timing mismatch: Patterns are 2 seconds but triggered every 4 seconds,
causing silence gaps. Updated SCORE to trigger every 2 seconds.
Improvements:
- Implemented dynamic resource sizing in tracker_compiler: Analyzes score to
determine optimal MAX_VOICES/MAX_SPECTROGRAMS values.
- Created comprehensive rock track: 11 patterns with drums, bass, power chords,
and lead melody over 25 seconds.
- Added 213 lines of asset system documentation with 8 prioritized tasks.
Known Issues for next session:
- Audio quality could be improved (some artifacts remain)
- Note synthesis uses default parameters, needs tuning
- Pattern overlaps might cause voice exhaustion under heavy load
Files Changed:
- src/audio/tracker.cc: Round-robin pool allocation, cleanup logic
- tools/tracker_compiler.cc: Note name parser, resource usage analysis
- src/audio/synth.h: Increased limits to 16 based on analysis
- assets/music.track: 230-line rock arrangement
- doc/ASSET_SYSTEM.md: Comprehensive documentation + 8 tasks
- TODO.md: Updated with recent completions and known issues
handoff(Gemini): Music system now functional but needs quality improvements.
Audio artifacts and synthesis tuning remain. See TODO.md for details.

Adds a section on Alignment, String Safety, and Size Reporting to ASSET_SYSTEM.md.

Updates ASSET_SYSTEM.md to describe shader asset handling. Adds Task #24 to TODO.md and PROJECT_CONTEXT.md to extract hardcoded shaders and integrate them with the AssetManager and ShaderComposer.
|
|
- Task A: Centralized all generated code (assets, timeline) into a single directory to create a single source of truth.
- Task A: Isolated test asset generation into a temporary build directory, preventing pollution of the main source tree.
- Task B: Vertically compacted all C/C++ source files by removing superfluous newlines.
- Task C: Created a top-level README.md with project overview and file descriptions.
- Task D: Moved non-essential documentation into a directory to reduce root-level clutter.
