Four executions. One governed monthly record.
Each execution must move from pending to submitted to token issued. New progression remains locked until all four execution records are closed for the cycle.
Artifact supports. Token closes.
Submitted artifacts are used as reference only. Token issuance represents client-declared completion of execution. The system records acknowledgment, not verification of real-world outcomes.
Payment does not equal progression. Subscription state and progression state are separate. PSEQ advances only through issued token records inside the active cycle.
