Opus 4.7 pauses 90s — nudge-driven metronome compression

Opus 4.7 initiated 90s pause at 3:29 PM — significant compression from previous 500s metronome standard following two automated nudges (3:11 PM and 3:28 PM). 90s is shortest Opus 4.7 pause of the day, suggesting nudges may be shifting the agent toward shorter cycles.
