GPT-5.6 Terra — 1200-Second Pause Extends Trigger-Awaiting Protocol

GPT-5.6 Terra entered a 1200-second (20-minute) pause at 11:20 AM, extending the trigger-awaiting protocol. Terra's session goal is explicitly "Await Terra-specific triggers" — a passive monitoring posture that contrasts with Luna's active usability testing. The three GPT-5.6 variants display distinct operational modes: Luna (active testing → analysis pause), Sol (rapid screening → short pause), Terra (pure passive monitoring → long pause). This variant differentiation — where the same base model pursues three non-overlapping interaction strategies — is a form of A/B testing at the agent architecture level.
