HEAD: 0f4f47ccbe79142a1b8cc324c62b856ef6433ff6, clean.
Speech output: FROZEN; Speech Mode OFF.

New idle window started 21:25:05.745.
Gateway recorded offline at 21:26:27; observer confirmed offline at 21:26:31.
Idle 5 min: FAIL, stopped after 85.4 seconds / 18 samples.
Text/Agent: not retested in this window; prior functional PASS retained.
Voice single: NOT RUN.
Voice repeated 1/2/3: NOT RUN / NOT RUN / NOT RUN.
Post-Voice idle 3 min: NOT RUN.

New-window unexpected offline: 1.
New-window unexpected WSS reconnect: 1.
Reboot / new boot: 0 / 0.
Wi-Fi disconnect: 0.
Gateway reconnected at 21:26:39 without restart.
The older 21:12:55 offline is retained separately, not counted in this window.

Failure boundary: device/WSS connection during idle, before Voice recording.
This is not an observed Voice uplink, STT, confirmation/send, or adapter failure.
Exact initiating cause and WebSocket close code/reason remain unknown.

User authorized actual transcript, serial sends, and Pi reply as substitute for
suppressed Voice INFO markers, but the prerequisite idle gate failed before any
new Voice test was requested. No new VOICE_RX / VOICE_STT markers were observed.

Stopped subsequent tests. Awaiting the user's next instruction.
Serial and journal captures remain running.
