What is measurable

Signal	`hotato autopsy ./call.wav` maps to this mode as detector kind `agent_start_during_caller`. Printed as TALK-OVER: the agent began talking while the caller still held the floor, reported with the overlap in seconds. Needs the caller and agent on separate channels.
Establishes	The moment the agent began speaking while the caller still held the floor, and how far into the caller's utterance it landed. What else it establishes, and what your own trace settles Every threshold behind the call is printed with the finding and every frame is inspectable. What your trace settles Your own trace at that timestamp names the stage that decided to start: endpointing, the turn detector, or a barge-in setting.
Tier	Tier 1 · dual-channel audio: caller and agent separated at capture, so overlap and timing are facts of the recording, exact to the sample. hotato is MIT and runs locally, getting started.

Removal	If you wrote something quoted on this page and want it gone, one email to [email protected] does it. The removal path takes the quote, the handle and the link off this page, out of the feeds and out of the llms.txt within 24 hours, and tombstones the id so the entry cannot quietly return at a new address.
