> `sendWindow.days` are weekdays from 0 for Sunday to 6 for Saturday, and the minutes count from midnight in `settings.timezone`. `null` removes the window.

> Send the `updatedAt` you read as `expectedUpdatedAt`, and a save that would overwrite somebody else’s change is refused with 409 `version_conflict`.

> An archived automation cannot be changed: 409 `automation_archived`.
