Pick how each workflow starts
A workflow can run on a clock, so the Monday morning report goes out before anyone logs in. It can run off an event, like an incoming webhook the moment a form is submitted or an order lands. And you can kick one off by hand when you just need it now. The same workflow can use whichever fits, and switch as the work changes.
A failed run repairs itself instead of stalling
A schedule or trigger only helps if the work still completes when no one is minding it. If a run hits a routine failure, auto-fix steps in, repairs it, and reruns, so the work finishes instead of sitting until someone notices.
