do you test webhook retries without drowning in fixtures?

Our provider retries aggressively and out of order under failure. Naive fixtures make CI slow and still miss race conditions. Looking for patterns that keep suites fast and realistic. Do you fake the provider clock, or replay recorded payloads? How do you assert idempotency without flaky sleeps? Share a setup that survived production incident recreations.

broke when we moved auth to the edge

We moved session checks to the edge to cut latency on every page load. It worked in staging, then failed on preview deploys when cookies crossed domains. Clock skew between edge and origin made short-lived tokens look expired. We fixed cookie domains per environment and added skew-tolerant expiry. Median auth path dropped about 120ms, with fewer cold-start surprises. Lesson: test cookies across every environment before calling a migration done.
