Raw audio never leaves the device (CS-1). Only stage-3 anchors cross the wire; σ_φ is measured locally and embedded in the world.
Open a shared set from Explore to listen and steer, or ingest audio + Train on cloud to build, play, and steer your own trained world right here. Training also measures a σ_φ calibration for your corpus, so after it finishes the instrument switches to your world — live to play and steer.
Open a shared set into Play and steer it with the same region-tilt lane. One instrument, many sources.
