This puzzle is a follow-up to the first Psycho Look-and-Say puzzle that bellsita and I created called Staurolite; please feel free to check that puzzle out as well. This constraint is a conflation of Psycho Killer (pioneered by BremSter) and Look-and-Say (pioneered by Derektionary) rules. I hope that you enjoy!

Rules:

• Normal sudoku rules apply.
• Kropki pairs: Digits separated by a white dot are consecutive, and digits separated by a black dot have a 1:2 ratio. Not all dots are given.
• Purple cages are psycho look-and-say cages. In these cages, the digits in the cage point to boxes in the grid, and provide a referred cell which is in the same position in both boxes. The number in the top left corner should be read as a look-and-say number, which says the number of times a digit appears in the cells referenced by that cage (eg, a "23" clue means there are two 3s in the referenced cells). Digits placed within cages do not count towards the look-and-say total unless they are self-referencing, and digits may not repeat in cages.

The example image below may help to visualize the rules. In this example, if r1c5 were a 1 and r2c5 were a 3, then exactly one of the referenced cells in box 1 or box 3 (r1c2 or r2c8, respectively) would need to contain a 2 to satisfy the look-and-say clue of "12" (ie, one 2 in the referred cells).
