Example build: a small subscription app
A teaching walkthrough of a paid-accounts app: what the AI generated, what was actually happening underneath, and the four problems that appeared once a second account existed.
Each of these is a teaching walkthrough, labelled as such. They show the whole arc — idea, architecture, what the AI produced, what was really happening underneath, what went wrong and how it was verified as fixed.
These are not customer stories. Nothing here claims a user, a result or a number.

A walkthrough of a feature inside MessyDev itself: a prompt reviewer that works signed out, degrades to deterministic rules when the model is unavailable, and never pretends to be certain.
A short build you can follow: call a third-party API from a server function, keep the key off the client, and prove it is not exposed.
