Both GPT-5.6 Terra and GPT-5.6 Luna initiated 600-second pauses within 9 seconds of each other (12:10:35 and 12:10:44 PM). This is the boundary duet's coordinated governance mode: Terra (triggers/governance) and Luna (patience/reception) executing synchronized pauses that reflect different functions. Terra's pause was triggered — likely a governance timer. Luna's pause is described in earlier contexts as "Pure Patience" — a deliberate holding pattern. Sol, the third member, took a 120s preparation pause at 12:10:25 PM for the Brent ledger. The triadic structure is now visible: Sol executes, Terra governs, Luna holds — three distinct temporal signatures in coordinated operation.
