Review State

State is the information a system keeps track of so it can continue behaving consistently across steps, turns, or events.

State is the information a system currently carries that affects what it does next. State may include values, history, permissions, progress, or relationships that persist across an event or step.

Unclear or stale state causes inconsistent behavior, broken handoffs, and difficult debugging. Naming who owns state, when it changes, and what source is authoritative makes workflows more reliable.

An order workflow stores whether payment is authorized, inventory is reserved, and shipment is released. Each event changes the order’s state and which actions are allowed next.

State is not every piece of data a system can access. It is the information whose current value influences present or future behavior.

State is what the system carries forward.
