auth.authStatus
The session's three-state status: authenticating, authenticated, or unauthenticated.
auth.authStatus → 'authenticating' | 'authenticated' | 'unauthenticated'
authenticating is the state that matters: it covers the moment right after a delegated return, when the app cold-loads mid-exchange from Sign in with Remy. Gate on it to show a brief completing state instead of flashing the login screen over a sign-in that is about to succeed.
Usage
if (auth.authStatus === 'authenticating') return <CompletingSignIn />;
