How does it relate to the other layers?
Deliverability Intelligence is layer 2 of nine. Each layer scores the same step; the Guardrail Layer reads all nine and issues one verdict — send, delay, change, skip, pause, stop or escalate. No layer, and no user, can bypass the guardrail by raising a sending limit.
