Keeping a thought together across pauses

Native audio work focused on two different problems: deciding when a person has finished a thought, and giving each saved transcript event an identity that survives a listener restart.

Earlier rolling-buffer and finalization behavior had duplicated old speech or split a natural thought too early. The retained V1.5 settings grouped nearby speech segments into a conversational turn, closing it after at least 1.20 seconds of silence. In the recorded natural trial, a 12.49-second thought stayed together and a separate 1.93-second phrase became its own turn.

Recognition still had limits. Repeated attempts at one proper name were transcribed incorrectly. The repeated short events were confirmed as separate spoken attempts, not evidence that the listener was duplicating them. Segmentation and word recognition needed to be evaluated separately.

The old sequence counter restarted at one for each process. V1.6 added a fresh runtime UUID and an event ID combining that UUID with the local sequence. Compilation and linking passed on the Pi. Four saved events from the first launch and one from the second had five distinct IDs, with the second launch correctly restarting its local sequence at one.

That was a scoped restart-identity result. It did not establish exactly-once processing, machine-reboot behavior, crash recovery, or power-loss durability. The audio transcript event was still standalone and had not been connected to the state or cognition pipeline.

A separate problem remained in log writing: the installed writer could announce success without checking stream failures. A correction was prepared locally, but the session stopped before its transfer, application, build, or Pi tests. This entry preserves that boundary rather than treating the proposed fix as installed. The session date is October 1 Eastern even though some UTC evidence falls on October 2.
