invoice_row_id (invoice row identity)

invoice_row_id is the stable identity of a sales invoice row. Bookkeeping uses row identity for traceability when postings, exports, or later corrections need to point to the exact commercial line that drove the accounting decision.

Row identity keeps the audit trail precise when an invoice contains multiple lines with different VAT treatments or income accounts.
