Why redundant email checks create data inconsistency
A developer found that requiring both an OTP code and a confirmation email link for signup created conflicting records. Users who entered the OTP and logged in never clicked the second link, leaving an 'email_confirmed_at' field null despite verified ownership. This illustrates how duplicate checks can produce contradictory data states.
