Audio gate cooldown blocks endpoint finalization

What this is

A local audio-level gate stops forwarding the caller's audio to the speech-to-text service after a brief silence cooldown, so the remote signal that would mark the turn finished never arrives and the call stalls.

Status acknowledged: the thread it was reported in was acknowledged upstream.

What is measurable

Signal	This record stands on its own linked sources. To put a number on your own call, `hotato autopsy ./call.wav` reads a recording you already have and ranks the timing incidents in it.
Establishes	Every report below links to the original post and names the handle that wrote it; the quote is at most 30 words around the reported failure. What else it establishes, and what your own trace settles The status changes only when a re-check stores the evidence link, the quote and the date behind the change. Every timestamp comes from the fetched artifact it describes, recorded with the sha256 of the response body it was read from. What your trace settles Reproducing the mode on your own stack is the next step: the reports below carry the configuration each reporter was running.
Tier	Atlas record: every field on this page traces to a fetched public artifact. hotato is MIT and runs locally, getting started.

Removal	If you wrote something quoted on this page and want it gone, one email to atlas-remove@hotato.dev 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.
