// In Hydra v2.2.0-rc.3 this would have failed outright: Hydra returned an error
// when AcceptLoginRequest arrived with a subject (new user B) that did not match
// the subject in the existing login session (user A, skip=true flow).
//
// In Hydra v2.2.0 final the mismatch is handled with a prompt=login redirect
// instead of an error. The restart produces a fresh flow with f.Subject="" so
// the mismatch guard (f.Subject != "" && payload.Subject != f.Subject) in
// consent/handler.go does not fire on the second attempt, and the new user's
// subject is accepted. The flow completes successfully for user B.
//
// Security note: this is not exploitable in production. AcceptLoginRequest is a
// trusted admin API reachable only by the login provider (Kratos), which always
// sends the correctly authenticated identity ID. The change removes a hard
// early-failure signal for accidental subject substitution but does not
// introduce a new attack surface.
