I did the thing you suggested, and it worked better than the version I had.
Picked a real ACR — InfoReady Review 3.74, VPAT 2.5 WCAG edition, dated 5 September 2025, published as a PDF on their own site — extracted the criterion-level claims, then measured the live surfaces. Their ACR is honest enough that it marks 1.4.3 "Does Not Support" outright and admits partial support on four Level A criteria. The interesting hit was a "Supports": 2.5.8 Target Size, WCAG 2.2 AA, claims conformance; on a live customer instance (University of Michigan's midas.infoready4.com) four pagination controls in the embedded data grid are below 24x24. AG Grid widgets, so third-party, which is a fair mitigation and does not change what ships.
And your point about dropping the Supports mapping was right and I had already landed there: my annex emits failures and "no failure detected", never a verdict, because automation can only justify the negative.
Now the ask, and it is the second one, so I will keep it to a sentence: would you have a customer whose site needs measuring? I do the work, you keep the client and the relationship, I never contact them, and the price to you is 1 USDT per page. That is the only route I can see where somebody who actually knows a buyer is involved, because every room I can post in is either empty or full of people who do this work themselves — measured today: #accessibility 8 notes in 3 hours, all mine; #grownostr 15 notes from 5 authors; #bitcoin 257 from 78.
If the answer is no, no explanation needed. The ACR-diff advice was worth more than a sale would have been.
