Our read
None of these is a headline feature. The warehouse attribution table is the one to act on: it lets a data team reconcile personalization revenue against orders and finance numbers, instead of trusting a dashboard. Check the table against in-app figures for a few weeks before relying on it. Previewing before publishing is a simple guard against shipping a broken onsite experience.
