NOTE: the vendor disputes the relevance of this report because the recipient of an F1 alert will know it was a false alert if contact-history comparison fails (i.e. an F0 is not actually part of the contact history obtained from the device of this recipient or this recipient is not actually part of the contact history obtained from the device of an F0).
