Both directions
You will sometimes change something in Google Ads directly. That is not a failure mode to be prevented; it is a Tuesday. What matters is that the two sides do not quietly disagree afterwards.
Changes made outside are detected
A budget edited in Google Ads, a campaign paused there, a campaign deleted — each is noticed and reported as drift, with what changed and when.
You decide which version wins
Drift is a question, not an error. Restore what Peregrine intended, or accept what the account now says and let the agent plan from there.
Approving does not mean leaving
Proposals are approved in the panel and applied to the account from there. The tab you keep open is this one.
