The 451 login answer escalates to last-resort account recovery through the
ap.two_step_verification.entrypoint_asyncaction (HTTP 200, no session): the app continues with that action (AccountRecoveryBloksEntrypoint) and shows the code-entry screen it opens ("Check your email"). The error is the login's server-decided outcome, so the caller can continue without reading the answer again. This is the 451 path; the older dialog withhas_identification_errorand achallenge_pickerContinue stays modelled separately.Guide: Errors
