PO Matching Looked Like It Halved Unsafe Invoice Approvals Until I Checked Why

Automated excerpt

Restricting to invoices whose PO world agrees with the truth removes that effect: v2 approved 151 invoices with 6 wrong, v3 approved 150 with 5 wrong. The PO check stopped 11 invoices and all 11 were wrong extractions (item text, the field a PO can see). Nothing about real invoices, purchase orders or the real registry.
