This module writes stack/runbook.md (failure half), which 3 later modules read. It is part of the paid course.
You make your system safe to run twice. You choose the one field that makes an item that item, write the ledger that remembers what has been done, and watch your second run turn into a no-op instead of a second message to the same person. You learn what partial failure looks like, when to retry and when to stop, and you write down the manual intervention path while it is calm rather than at three in the morning.
Twelve modules, thirteen files. From typing into a box to a working setup you own — no technical background assumed.
Build AI that acts. Sixteen modules, fourteen files, two tracks, and the rules written down before anything runs.
Twenty-eight modules end to end, in the order they were meant to be read.
After you pay: a sign-in link lands in that inbox and the first paid module opens. Usually under a minute.
