Prompt

Given [METRIC SERIES] and [KNOWN EVENTS], investigate a sudden change without inventing causation. First check definition, tracking changes, missing records, seasonality and comparison period. Then list up to five hypotheses with supporting and disconfirming evidence, and the cheapest query or chart to test each. Separate business change from instrumentation failure. Return an evidence ladder, a cautious one-paragraph stakeholder update and a plan for the next 48 hours. Do not attribute the jump to a campaign or product release merely because dates overlap.
