The brief
Normal Sudoku Rules Apply. Any set of three sequential cells along a teal modular line contains one digit from (1,4,7), (2,5,8), and (3,6,9). Cells along a pink renban line must for a consecutive set, in any order. Cells equidistant from the centre of the purple ZIpper line sum to the circled digit in the centre. Cells in a killer cage must sum to the clue in the corner MOD 3. Diagonals marked with arrows must sum to the clue given MOD 3. Digits joined by a black or white dot must be in a 1:2 ratio or consecutive respectively. No digits may repeat on any of the given lines (Little killers do not obey this rule) No other negative constraints.
The brief doesn't say what the black dots mean. We read them as standard Kropki dots (a black dot joins digits where one is double the other), which the setter's solution confirms.
