Hold the learning setting before intervention

For Product GMV Max, preserve the ROI target for at least three full days before changing it unless a documented safety or business stop rule requires earlier action. Record actual spend, budget utilization, product set, and the reason for intervention.

The three-day platform guidance is not an economic guarantee. Seller-owned contribution and restoration controls still govern action.

Run the nine-confirmation close

At weekly close, a second reviewer checks all nine confirmations, the closed duration, source and policy dates, report and attribution definitions, refund maturity, fees, commission, costs, optimization mode, prior result, backup, and tested restoration.

Any no or unresolved issue returns the packet to Block. The calculator never changes a campaign, budget, target, product set, or creator setting.
