q-pilot

1// q-pilot: checks that the user flows of a web app still work. It records the files the main loop
2// edits, and when the main turn tries to stop after UI-relevant edits it runs the affected flows with
3// the runner (a Node CLI): replay of a recorded trace, a Jev re-pick of one changed step, and a
4// verify block judged by code. Red flows block the stop; drift blocks until the person accepts it
5// (or, with trust on, until the turn's diff shows the change was intended).
6// When the classic Stop hook never reaches this module (managed settings can bypass user plugins'
7// classic.Stop), the main turn's turn.complete runs the same gate detached and, on red, submits the
8// failures as a follow-up prompt. Every hook and every helper that takes `$` lives in this file (the
9// engine follows `$` only within one module); pure helpers are in ./lib.
