The event acts on something the party directly depends on or faces: a counterparty, a supplier, a regulator, a rival.
The product’s working definition.
One step removed and still exposed through a named channel: a counterparty, a supplier, a regulator, a rival. The event does not touch the party, but the thing it depends on.
How directly an event reaches a party, on the intersection cards an Event Scan or an Entity Scan renders.
Every grade here is assigned by the same rules on every scan, and the methodology page renders those rules from the code that enforces them.
