"you follow your own advice and actually look at the IRS eligibilty."

Well, yes, that's what I did. As I noted: "Most times, the seller will include the certification, if it meets whichever various requirements."

And here is what the IRS tells you in the instructions for Form 5695:

https://www.irs.gov/instructions/i5695#en_US_2023_publink1000122131

"Manufacturer’s certification.

For purposes of taking the credit, you can rely on a manufacturer’s certification in writing that a building envelope component is an eligible building envelope component. Don't attach the certification to your return. Keep it for your records."

Things will drive you crazy, if you let them. It can be a short trip.
