The money is published; the names are held. Each row below carries the contract value, what has been paid to date so far as it is published, and our confidence grade — the same figures as always, from the same official records. What is withheld is the vendor's name, the record link that names it, and the campaign-finance search that sat beside it. That is a deliberate decision taken pending legal review, not a figure we could not find: a blank cell would have said the opposite. What WITHHELD means
