Great puzzle! Delightful and smooth solve path the whole way through! Thank you!

(For the record, it also solves uniquely if both the yellow dots are regular kropki dots, which is cool! I'm sure there's some math thing explaining that)

Lovely puzzle. It's the second time of the day that I completely misjudge a clue and get a unique solution. For the fun, if the kropki dot in box8 was white, the puzzle has also a unique solution.
