Zero to a deployed system, one falsifiable checkpoint at a time.

Forty nodes across eight phases. Each one gives you a goal, two resources, a coding session, and a checklist you can genuinely fail. Nodes unlock when their prerequisites are passed — locked ones stay visible, so you can always see the shape of the road ahead.

All forty nodes are written. Nothing here has been through a pilot yet, so expect rough edges — and if a checklist item is wrong, that is a bug worth reporting.
