Every upgrade of a runtime or a database has to reach every file that installs it: the dev container, the Copilot workflow, the Cursor environment, the server script. Miss one, and one agent works on a different version from everyone else, which shows up later as a bug nobody else can reproduce.</p> <p>In the Alpha demo, the orders-api team moves from PostgreSQL 16 to 17. One line changes in <code>preconfig.yaml</code>. <code>preconfig check</code> lists every file that is now out of date, <code>preconfig build</code> rewrites them, and check is clean again.</p>
