Turns out that implementing a cyclically wrapping domain properly is much more tricky than initially anticipated. After initial analysis I decided where to draw the line and what ''esoteric features'' aspects to leave out. Then I used Knowledge-Technology (Claude) to scrutinise and improve my implementation, and to learn a lot more about integral arithmetics in general.
