Capture from Pipecat

setup drops a pipeline recorder: caller and agent on separate channels, to score offline.

1. Add the recorder

setup prints an AudioBufferProcessor recorder: input (caller), output (agent), writing one WAV with caller on channel 0.

uvx hotato setup --stack pipecat

2. Score the recording

Point Hotato at the WAV the recorder wrote. --expect yield/hold = interruption vs. backchannel.
