Extracted from op-pedal mixer-engine branch. Core components: - MixerEngine / MixerChannelStrip / MixerBus — cleaned of LV2/Pedalboard/IHost/MidiMapper deps - MixerControlServer — Unix domain socket JSON control interface - main.cpp — JACK audio I/O client with headless fallback - CMake build — auto-fetches nlohmann/json, links JACK - 9 core tests passing Architecture: JACK ports → MixerEngine::process() → JACK ports, controlled via Unix socket JSON commands.
