I enjoyed the grid fill and working out the unclued entries. I like others was a bit uncertain about the three cells to highlight. There is one obvious word that drops out of the three longer entries. It does not appear in the grid in a straight line. It does appear in 3 cells that are contiguous but not in a straight line. It felt wrong.
Then the penny dropped. I should read the preamble more carefully and not make assumptions All fine now.
Nice one Dimitry.
