Notifications

Historical preview of a rule shape

Replay a rule shape (which may or may not be saved yet) against the last N days of data and return time-series buckets with threshold breaches + the exact number of notifications the state machine would have emitted.

Powers the chart in the rule editor: as the user tweaks metric, aggregation, threshold, window, filters or the re-notify cadence, the client re-calls this endpoint and re-renders the chart. Bucket size is always equal to the rule's evaluation window so each bucket's value represents one real evaluation.
