Workspace for SoundCraft, a clean-room pure-Rust Pro Tools-class DAW: timebases and tempo maps, WAV/AIFF/FLAC/symphonia audio IO with peaks, SMF and MIDI ops, 26 original DSP plugins, the session model, the mix engine, ~180 registered commands with undo, a cpal player, and the agent rules (AGENTS.md, ATTRIBUTION.md).
