This list lives in your browser. Nobody else can read it, including us, because no copy of it was ever sent anywhere. Each receipt folds in the head of the one before it, so the run checks out as a whole or tells you exactly where it stopped.

What a broken run looks like. The second receipt was rewritten, so its head stops matching and every head after it inherits the break.
How to check this without us
Export the pack and recompute each head yourself: sha256(previous_head + "\n" + payload), with an empty string standing in for the previous head of the first receipt. Every signature from an ordinary wallet checks against the address written beside it with arithmetic alone. The pack needs this site for nothing.
