Hey HN,I built Verity after debugging a production issue where our job platform was sending duplicate emails to tens of thousands of hotel guests.We were running automated checkout for a chain of hotels across Germany, Spain, and New York. The process had multiple steps: validate reservations, generate folios, check guests out, send receipt emails.The job would run for 25+ minutes processing thousands of reservations. Sometimes it would time out at 30 minutes. The platform would see the job didn't complete and restart it from the beginning.The problem: some operations were idempotent through the provider (like creating a folio with the same ID), but others weren't (like sending emails).
