"""reproduce_receipt_verify.py — feeless402 PR#4 receipt.verify() bug.

Demonstrates that nano_pay.receipt.verify() raises Mismatch on a REAL
confirmed send, because it compares the caller's `account` (the payee the
seller expected) against block_account — which in block_info is the block's
AUTHOR (the payer), not the destination.

The canned reply below is copied verbatim from a live block_info answer
(rpc.nano.to / rainstorm.city, 2026-09-26) for pursekeeper's confirmed
2.499999-XNO send F68B9E8B...0BA7EDA (its parley member-pass payment).

Run from a feeless402 checkout:
    python3 reproduce_receipt_verify.py            # against master  -> Mismatch
    # apply receipt_verify_fix.patch, then again   # against fixed   -> settled
