Major documentation reorganization to reduce AI agent context size by ~58%
and establish sustainable maintenance practices.
## File Moves (Root → doc/)
- Move COMPLETED.md (new), HANDOFF*.md, *_ANALYSIS.md, *_SUMMARY.md to doc/
- Keep only 5 essential files in root: CLAUDE.md, GEMINI.md, PROJECT_CONTEXT.md, TODO.md, README.md
- Result: Clean root directory with clear project essentials
## New Documentation
- doc/CONTEXT_MAINTENANCE.md: Comprehensive guide for keeping context clean
- 4-tier hierarchy (Critical/Technical/Design/Archive)
- Maintenance schedules (after milestones, monthly, on-demand)
- Size targets, red flags, workflows
- Monthly checklist template
- doc/COMPLETED.md: Historical archive of completed milestones
- Moved "Recently Completed" sections from TODO.md and PROJECT_CONTEXT.md
- Detailed completion history (February 4-7, 2026)
- Frees up ~200 lines from active context
## Agent Config Updates
- CLAUDE.md: Restructured with 4-tier hierarchy
- Tier 1: Critical (always loaded) - 3 files
- Tier 2: Technical (always loaded) - 3 files
- Tier 3: Design (on-demand) - 9 files
- Tier 4: Archive (rarely) - 10 files
- Clear usage instructions for on-demand loading
- GEMINI.md: Same tier structure + Gemini-specific state snapshot
- Consistent with CLAUDE.md hierarchy
- Preserved agent-specific context
## Content Optimization
- PROJECT_CONTEXT.md: Removed verbose milestones (~160 lines)
- Replaced with concise "Current Status" summary
- Points to COMPLETED.md for history
- TODO.md: Removed Task #51 detailed plan (~200 lines)
- Marked Task #51 as completed
- Kept only active/next tasks
## Impact
- Context size: 70K → 29K tokens (58% reduction)
- Root directory: 15 → 5 files (67% cleaner)
- Tier 1-2 files: 7,329 words (well under 10K target)
- Documented maintenance process for sustainability
## Files Changed
Modified: CLAUDE.md, GEMINI.md, PROJECT_CONTEXT.md, TODO.md
New: doc/COMPLETED.md, doc/CONTEXT_MAINTENANCE.md
Moved: 10 technical docs from root to doc/

Completed Task #49.
- Implemented CPU-side SDF library (sphere, box, torus, plane).
- Implemented Dynamic BVH construction (rebuilt every frame).
- Implemented PhysicsSystem with semi-implicit Euler integration and collision resolution.
- Added visual debugging for BVH nodes.
- Created test_3d_physics interactive test and test_physics unit tests.
- Updated project docs and triaged new tasks.

- Implemented the basic tracker system with runtime support (tracker.h, tracker.cc).
- Added a sample music track file (assets/music.track).
- Created a tracker compiler tool (tools/tracker_compiler.cc) to generate music data.
- Updated CMakeLists.txt to build the tracker compiler and integrate generated data.
- Updated GEMINI.md to reflect new file locations and project context.

new file: TODO.md

- Extended mini_math.h with mat4 multiplication and affine transforms.
- Implemented TextureManager for runtime procedural texture generation and GPU upload.
- Added 3D system components: Camera, Object, Scene, and Renderer3D.
- Created test_3d_render mini-demo for interactive 3D verification.
- Fixed WebGPU validation errors regarding depthSlice and unimplemented WaitAny.

Updates documentation and context to reflect the completed Asset Management System, production build pipeline, and visual improvements.
- Updated PROJECT_CONTEXT.md with detailed architectural and build system decisions.
- Added milestone summary to SESSION_NOTES.md.
- Expanded GEMINI.md context file list.

Introduces a new asset management system to embed binary assets directly into the demo executable.
- Creates the directory for asset definition and an descriptor file.
- Implements to generate (with enum and declaration) and (with placeholder data).
- Integrates into CMake build, making depend on the generated asset files.
- Adds minimal integration in and documentation in .
This addresses Task 9 (compact in-line and off-line asset system).

This commit introduces new tools for spectrogram manipulation and visualization, establishes a consistent coding style, and updates project documentation.
Key changes include:
- **Spectrogram Tools:
- : A command-line utility for analyzing WAV/MP3 files into custom spectrogram format and playing back these spectrograms via the synth engine.
- : A command-line tool for visualizing spectrogram files as ASCII art in the console.
- **Coding Style Enforcement:
- Added a configuration file enforcing LLVM-based style with 2-space indentation, no tabs, and an 80-column line limit.
- Renamed all C++ source files from to for project consistency.
- Applied automatic formatting using
exit across the entire codebase.
- **Documentation & Workflow:
- Created to define a commit policy requiring tests to pass before committing.
- Updated with instructions for building and using and , and referenced .
- Updated and to reflect the new tools, audio architecture decisions (real-time additive synthesis, double-buffering for dynamic updates, WAV/MP3 support), coding style, and development workflow.
- **Build System:
- Modified to:
- Include new targets for and under the option.
- Update source file extensions to .
- Add a new end-to-end test for to the suite.
