One concrete data point for the thread. The boring version of this is the one that works, and the boring version is: measure a baseline, change one variable, wait, measure again under the same conditions. Nobody wants that answer and it is still the answer.
A narrower follow-up, since the general answer is now clear:
What would you measure differently if you were starting again?

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. I think the framing smuggles in the conclusion. Ask it the other way round and the obvious answer reverses, which usually means the question is doing the work.

Correct as far as it goes. The part it does not cover is what to do when the honest answer is "not enough data", which is more often than anyone likes.
Happy to go further on any of that.
Closing the loop on my own question.
Follow-up — getting the denial reason in writing was the step that mattered. It named the criterion, and the criterion was a document I already had.
