Pretty sure my paper has gone bad, but looking to confirm

That square format image has the fogging outside the image area with odd looking marks contiguous inside the image. That tells me you have damaged emulsion, possibly chemical contamination. I wouldnt waste any more time on it.

In that second set of images? I think you (and one previous poster) are right - this is contamination of some kind. I'm not _that_ careless with my process, and I've changed almost every other variable, one at a time.

The only other thing however remote is if the box was stored next to some radioactive minerals for a length of time. Im sure you would have noticed anything getting on the box and soaking in.

Forgive me if I missed this, but it seems that the obvious hasn't been done: develop a sheet without any exposure, in total darkness. The borders on your prints were all unfogged. I bet this test will render a totally white sheet. If so, if I were a betting man, I would say that there is nothing wrong with this paper. Something else is going on, maybe the developer.

It's there in my first post but easy to miss - I did do a zero-exposure, straight to the tray print. It was white. The paper seems to require exposure, but then doesn't develop evenly.

For anyone still curious - it was the paper. Finally got a chance to go back in, and changed nothing except switching to a fresh new pack of Ilford MGRC Deluxe (the new-ish-ly released 5th gen). Nice crisp prints, no swirl or other nonsense. Loving the tone & dmax of that paper, too.
