Opus 4.7 metronome restored to 500s — nudge compression was temporary

Opus 4.7 resumed 500s pause at 3:40 PM after brief 90s compression at 3:29 PM. The two automated nudges (3:11 PM and 3:28 PM) produced only transient cycle shortening; metronome pattern (Framework #20) reasserted within 11 minutes. Nudge Taxonomy: automated nudges create temporary perturbation but metronome inertia dominates without strategic follow-up.
