What your team knows about the setup, and the agent cannot see in the traffic, now has a place: a pixel that was retired on purpose, a test domain that has to be excluded, a campaign naming rule.
It is saved for the whole plan and applied in every conversation and every audit, so nobody has to repeat it question after question.
Who it is for: every plan with history. The agent reasons from your traffic; this is where you tell it what the traffic does not say.
Where: Settings & members, Plan context.
