The "Originator Address" block as the three discrete lines Fedwire carries. Numbered rather than a list because the number is part of the address: a wire with lines 1 and 3 populated must not have line 3 read as line 2.
The bank's wire sequence number, or null when the notification carries no
usable one. Fiserv emits a literal * placeholder on some wires, so this
cannot be relied on as a key — imad is the stable identifier.
The trailing digits of the CFX account the wire moved through, as the notification quotes them —
454from "Credited to account ending with 454". Three digits in every message seen so far, never a full number, so this identifies an account only in combination with the bank.Null when the notification carries no account line at all, which is ordinary rather than exceptional: Burling omits it on every debit. It is therefore NOT part of the irreducible date/amount/IMAD set in parseCommonFields — a missing suffix must never make an otherwise good wire email unparseable.
