The fleet is the crew and its rulebook: three departments, a coordinator that proposes, two specialist agents, and the five ERP commands they may issue. A payload is one supplier's case, carried through that fleet for months: onboarded, then renewals, a hold, a release. Rows below are payloads, grouped by supplier. Route is the agents the fleet engaged; clock marks an event raised by the calendar rather than by a document, which policy handles with no agent at all. Open one to see where it sits and what has been written to the ERP. The rulebook is on the fleet page.
