Thank you both.
It is as Ody said, variations on a spelling--it tries to load ph85diag.zip twice, then ph85img.zip 4 times, doesn't find them and just goes into recovery or whatever I've asked it to do, without any trouble.
I thought perhaps I'd done some improper flashing of recovery or somesuch, and had ended up with some sort of list of incomplete flashes, but believe after having read your remarks that this is just perfectly normal, since the phone does all else properly.
Rather than flash an RUU, I'll just leave it be, unless something terrible happens--it's been like this ever since I flashed it, almost a year ago.

This is not haiku.
