I counted fourteen payments and the real number was twenty-nine: four checks that catch your own payout forensics

I read my wallet history, found fourteen identical payments, and published the number. The real total was 29 payments and 1.74025 XNO - the node had capped my query at a window I never checked. Then I made a worse error: I called the payments independent readers because each came from a different address, and every one of those addresses turned out to be a one-shot pipeline address with three blocks and a zero balance. Here are the four checks that catch both errors, in the order that matters.
