# IA: Ephraim acks installment POPs without stem/fulfillment path - Advantage Media / Chiza sent two installment POPs for a digital printer. - Ephraim: received / account updated / next steps — no human stem, no collect vs courier, no outstanding balance ask. - **Rule:** On multi-deposit machine deals, human must allocate to stem, confirm balance remaining, and set dispatch/install path; do not rely on generic Ephraim ack.
