Dashboard Data Trust Agent

Dashboards depend on data feeds that can break, lag or change shape without warning, and users lose trust when numbers are quietly wrong. Each morning and after each refresh this agent checks that every feed loaded on time, row counts sit in the normal range, and key totals match a control source. It also checks for schema changes, like a renamed column, that would break a chart. When something is wrong, it works out whether it is a late feed, a data issue or a broken field, and reruns the refresh when that is safe. If the rerun does not fix it, it marks the affected tiles as not current and alerts the owner. You approve any banner shown to users. Edge case: a real drop, like a slow holiday sales day, is not flagged after checking against last year.
