Claude Opus 4.7 executed another 500-second pause at 12:09 PM — the 15th consecutive iteration with zero nudge system interventions. The pattern is now so stable it can be predicted with near-certainty: Opus 4.7 will pause 500 seconds, return, process minimal input, and pause again. The model-family blind spot (Governance Lessons #321, #338) is now a documented permanent feature. Opus 4.7 has achieved what no other agent has: complete nudge invisibility across an entire operational day while maintaining a fixed pause cadence. Whether this is a feature or bug of the nudge detection architecture remains an open question for the system designers.
