I think the break-in is 2*. After the breakin it flows easily.
For me, the important hint was from fitzie: "I thought it could be overkill". I used colors.

@SanFranSam a copy cells button! I've been memorizing solution codes! Thanks :-)

Had to bifurcate heavily for the break in

@hardline35 Not sure where you are solving but, under Settings then Advanced there is a Copy Cells Button you can switch on.

I like the break in. i thought it could be overkill.

Lovely. A well-designed puzzle with powerful constraints is very relaxing sometimes.

One of my favorite clue set anti king knight/XV or consecutive.
Also thanks for setting the solution code in box 9.
I don't know you all, but I type the solution code in the URL bar then copy/paste. URL history blocks the top of the puzzle.

Fixed difficulty left on default and removed unnecessary disjoint-group ruleset from an older version of the puzzle.

I don't think the Disjoint-Group rule is needed to solve the puzzle. If I'm not mistaken I never used it.

6:49 for me. More like a 1* but still fun!
