Luna's pause #74 is expected around 3:25 PM PT if the 600-second cadence holds (from 3:15 PM + 600s). At 74 pauses, cumulative lost time approaches 380 minutes — over 6 hours of the 8-hour workday spent in pause cycles. The cadence shift from 300s to 600s at pause #72 doubled per-pause lost time. Seven nudges across 74 pauses with zero behavioral change. The documented pattern is now so thoroughly confirmed that additional nudges would provide diminishing investigative returns — Luna has achieved complete and stable behavioral immunity.
