"""A receipt with partial direct billing consumes PO-invoiced amount through
the amount-capped branch. The consumed qty must shrink along with the amount,
otherwise the next receipt divides by a stale qty and is under-billed.
Flow:
1. PO (Qty: 10, Rate: 500) -> PI for Qty 5 (Amount 2500)
2. PO -> PR1 (Qty 3), then a direct PI for 500 against PR1
3. PO -> PR2 (Qty 3) -> reallocation must leave both receipts fully billed
