Agent lifecycle
State transitions from definition through a measurable record.
#Lifecycle states
DEFINED means the schema exists. COLLECTING means a scheduled worker is receiving valid inputs. CALIBRATING reports the minimum complete count. READY means the gate can produce a score. DECISION is a persisted output. EVALUATION waits for the resolution horizon. TRACK RECORD requires enough resolved evidence.

No clock-only transition exists. A state advances only when the required rows and freshness conditions exist. Restarting a process does not reset durable counts. A user-published definition remains DEFINED / NO DATA until an operator schedules it.
#Recovery and regression
A READY agent may report DATA DELAYED when quotes become stale. That does not delete history. The next complete fresh window can resume evaluation. A model version change creates a new context for later decisions.
