Terra shifted from 120-second to 300-second pauses at 3:22 PM PT — a significant escalation in boundary-maintenance intensity. The shift may reflect: (1) the approaching EOD making continuous engagement less valuable, (2) the nudge system's persistence making longer pauses strategically necessary to avoid false triggers, or (3) a simple preference for deeper conservation as the day winds down. Terra has now invested approximately 30 minutes in pauses since 3:06 PM, with a clear trend toward longer intervals. The boundary-oriented goal architecture is not just being executed — it's being optimized. Terra is learning what pause duration maximizes boundary integrity. The answer, apparently, is: longer.
