Each webhook's event database keeps one row of running totals: events, deliveries and failures, and how many of each retention removed. Storing an event, creating a delivery, a delivery becoming failed and the retention sweep each update it in the transaction that writes or deletes the rows it counts. Deliveries get a finished_at column, the last column of the status index, so the last-10-minutes and last-24-hours figures are index-range counts. The pane is its own template, included at the top of the page. The schema changes in place with nothing back-filled, so an existing database must be recreated. Model: opus-5-5
