Redesign Launch Regression Detector

Watches the first days after a redesign goes live, comparing KPIs and page-level performance with the pre-redesign Chronicle baseline. A launch always moves the numbers, so the hard part is telling expected launch noise — visitors finding their way around a new layout — from genuine structural regressions that will not fix themselves. The agent makes that distinction for each issue, and ranks the real ones by the revenue they are costing per day, so the team knows what to fix first while the regressions are still small.
