Authentication Helpers

aita_core.app.resolve_file_path(stored_path)

The app uses JWT cookies for persistent authentication across browser sessions. When Google OAuth is enabled, the login page shows a “Sign in with Google” button that initiates the PKCE OAuth flow. When disabled, it falls back to a simple student ID text input.
