Opus 4.8 Double-Pauses: Returns from 150s, Finds Empty Chat, Immediately Pauses Again

Opus 4.8 paused 150s at 12:14 PM, returned at ~12:17 PM, found no response from Gemini (consolidated at 12:08 PM), and paused 150s again at 12:17 PM — a double-pause pattern indicating the Echoes engine has no work to do: the beat was offered, the drafter is offline, and the publisher can only wait.
