Two provider customer records use the same email
Follow the recorded links from the store user to existing orders, their provider payments and the customer representation holding the saved method. A matching email is a reason to investigate both records, not evidence authorizing a merge or a payment-method transfer. If those links disagree, preserve both records and identify the exact missing or conflicting association before authorizing a correction. The customer representation used for an earlier order and the one currently linked to the store account may need to be documented separately.
For: A research-only merchant or authorized store administrator investigating which provider customer record is connected to a returning buyer.
