Rules: Standard Fillomino rules. Also, each letter represents a different positive integer.
Answer String: For each cell in the marked rows/columns, enter the area of the polyomino it belongs to. Enter just the last digit for any two-digit number.

A great puzzle. I’ve found the recent cipher puzzles, (both of Palmer’s Fillominos and Grant’s Pentominous), to all have excellent openings with very satisfying logic. Keep them coming!
On this particular one, I was nearly done at 28:30 when I realized I had broken the puzzle, (a silly error failing to imagine a potential orientation of a small polyomino caused me to mis-assign the relative sizes of the two largest letters). Even with that, I thoroughly enjoyed this one.

Your assumption can be proven at the start. Think of what happens if gurer vf n bar va gur pragre.
Oddly enough it took me a while to see that. Once I did I was kicking myself for not seeing it sooner. 🙂
Then again, when I discovered the area of the largest polyomino I was surprised for some reason and my first thought was to wonder if I had made a mistake somewhere, but I hadn’t.
