//  SignInTestHook.swift
//  AT-IRC
//
//  Debug-only sign-in automation for the iOS Simulator.
//
//  With ATIRC_SIGNIN_HANDLE in the launch environment, LoginView signs in
//  automatically and writes the authorization URL to a 0600 file in the app
//  container. scripts/sim-signin.sh reads that file and drives the browser
//  through the authorize page using ~/.aliceoa_bsky_social_source (via
//  socialweb scripts/oauth-signin.ts). The URL is never printed or posted;
//  the script removes both files after the attempt.
