What the listing says

Check that an advertised catalogue matches the challenges actually served. Reports a resource advertised and not served - a dead listing a buyer follows to nothing - and a resource served and not advertised, which nobody can discover. Compares advertised price, network, asset and payee against what the challenge really says, since a buyer budgeting from a listing budgets wrongly when they disagree. Nothing is paid.
