29 hours	feat(audio): Implement audio backend abstraction (Task #51.1)	skal
	Created interface-based audio backend system to enable testing without hardware. This is the foundation for robust tracker timing verification. Changes: - Created AudioBackend interface with init/start/shutdown methods - Added test-only hooks: on_voice_triggered() and on_frames_rendered() - Moved miniaudio implementation to MiniaudioBackend class - Refactored audio.cc to use backend abstraction with auto-fallback - Added time tracking to synth.cc (elapsed time from rendered frames) - Created test_audio_backend.cc to verify backend injection works - Fixed audio test linking to include util/procedural dependencies All test infrastructure guarded by #if !defined(STRIP_ALL) for zero size impact on final build. Production path unchanged, 100% backward compatible. All 13 tests pass. handoff(Claude): Task #51.1 complete, audio backend abstraction ready Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
2 days	refactor(build): Modularize build system with static libraries	skal
	Completed the first part of Task #25. Created static libraries for each subsystem (audio, gpu, 3d, util, procedural) and refactored all executables to link against them. This improves modularity and simplifies the build process. Also fixed linker errors related to glfw, wgpu, and miniaudio.
2 days	feat: Finalize tracker asset-sample integration with unified pasting strategy	skal

5 days	clang-format	skal

5 days	style: add vertical compression rules to clang-format	skal
	- Enabled AllowShortFunctionsOnASingleLine: All - Enabled AllowShortBlocksOnASingleLine: Always - Enabled AllowShortIfStatementsOnASingleLine: Always - Enabled AllowShortLoopsOnASingleLine: true - Set MaxEmptyLinesToKeep: 1 - Applied formatting to all source files.
5 days	fix: Cross-compilation and style compliance	skal
	Fixes seq_compiler build for Windows cross-compilation. Moves common WebGPU compatibility shims to gpu.h. Applies project-wide coding style via clang-format. Verified on both macOS (native) and Windows (cross-compile).
5 days	opt: Guard debug/seek features with STRIP_ALL	skal
	Ensures that code related to the --seek command line option (simulation loops, silent audio rendering) is completely compiled out when the DEMO_STRIP_ALL build option is enabled, preserving the 64k size constraint.
5 days	feat: Add --seek command line option for fast-forward debugging	skal
	This feature allows developers to jump to a specific time in the demo sequence (e.g., './demo64k --seek 10.5'). It simulates the game logic, audio state (rendering silent buffers), and visual physics (compute shaders) from t=0 up to the target time before starting real-time playback. Audio initialization is refactored to separate device init and start.
5 days	fix: Resolve macOS build breakage and restore tools audio support	skal
	Updates gpu.cc to handle modern wgpu-native callback signatures (5 args) for macOS while maintaining Windows compatibility. Modifies audio.cc and CMakeLists.txt to ensure miniaudio encoding features are only stripped from the demo binary, not the tools (spectool/tests).
5 days	opt: Disable unused audio formats (FLAC, WAV, MP3) and encoding in miniaudio	skal
	Reduces Windows binary size from 461KB to 356KB (UPX packed) by stripping unused decoders and encoders from the runtime build. Tools (spectool) retain WAV/MP3 support.
6 days	Chore: Add missing newlines at end of source files	skal

8 days	update asset system	skal

8 days	style: Add 3-line descriptive headers to all source files	skal
	This commit applies a new project-wide rule that every source file must begin with a concise 3-line comment header describing its purpose. - Updated CONTRIBUTING.md with the new rule. - Applied headers to all .cc and .h files in src/ and tools/. - Fixed various minor compilation errors and missing includes discovered during the header update process.
9 days	feat: Implement spectool & specview; refactor coding style; update docs	skal
	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.
