Diarization had no probe, so a speaker pod could only ever report reachability —
and reachability is what reported ok:true for an STT image that shipped nothing
for speaker work at all. espeak provides the audio; the check is that the model
returns at least one labelled turn, which a pod with no diarization stack
cannot do.

One speaker saying one sentence is a thin test musically and an honest one here.
