Rules:
Renban Lines: Digits along a purple line form a set of consecutive digits, in any order.
Quadular Lines: Every 4 consecutive cells along a blue line must contain a complete set of residuals modulo 4. i.e: one from (4,8), one from (1,5,9) one from (2,6), and one from (3,7).
Mod-4 Cages: Digits cannot repeat within a cage. The number given in the upper left of a cage is the remainder of the cage’s sum divided by 4. (e.g. if a 2 is given in the upper left, the cage sums to one of 2, 6, 10, 14, …).

There were some intriguing interactions between the Renban lines and the rarely seen mod-4 lines and cages, not just for the break-in. At the start, this felt impossible to solve, and in the end, it still felt harder than 3*. Thanks for sharing.
