}Link a bank line to the transfer journal entry that already booked it
accounting:writeLinks an unreconciled bank feed line to an EXISTING bank-transfer journal entry and posts nothing.
The problem it solves. Banks post the two legs of one internal
transfer on different days. When the first leg is recorded as a transfer
and the second arrives afterwards, the second leg has no twin to be
matched against (the first is already matched), so the only other verb
available records a SECOND transfer entry for the same money — one bank
GL permanently overstated, the other understated. This endpoint is the
alternative: the movement is already on the books, so the line is
attached to the entry that booked it.
The server re-validates, and the caller cannot steer it. The
journal_entry_id must still satisfy the same predicate the review
queue proposed from, re-checked under a row lock: a posted, unreversed,
unvoided CASH_MOVEMENT entry whose single attached bank line sits on
ANOTHER of this entity’s bank accounts, carries the same amount in the
opposite direction within 2 days, is not pending, and whose own memo
reads as a transfer between the operator’s accounts. Anything else is
422 transfer_link_invalid.
Bounded and idempotent by construction. A candidate entry must have exactly ONE bank line attached today, so once this call succeeds the same line cannot be linked twice and no third line can be attached to a transfer that already has both halves.
No GL postings occur. One audit row
(bank_transaction.linked_to_transfer) and one
bank_transaction.matched event. Undo is the normal unmatch: the line
is restored to unreconciled and the journal entry is left alone.
