The explainable agent framework — backtrack a wrong answer to the exact context that caused it (evidence, not guesses). Built on footprintjs.

/**
 * hosting/signin/source — the lifetimes, applied in ONE place.
 *
 * `signInSource` turns a {@link SignInStore} (which only keeps records) into a
 * {@link SignInSource} (which answers "who is behind this key, right now?").
 * A sign-in is live while BOTH clocks allow it:
 *
 *  - the absolute lifetime (`SignIn.expiresAt`, fixed when it was created —
 *    8 hours by default at the sign-in door), and
 *  - the idle limit (`idleMinutes` since `SignIn.lastSeenAt`) — 30 minutes
 *    under an SSO strategy, where signing in again is silent, and 60 under a
 *    password strategy, where it means retyping.
 *
 * A sign-in found past either clock is DELETED and reported ended, so the next
 * request does not find it either and an open socket carrying it closes. The
 * honest costs, stated rather than implied: a person disabled at the IdP keeps
 * access until their sign-in ends, and their roles are frozen at sign-in for
 * the same time — the library does not poll the IdP.
