Hidden in plain sight

Normal sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box. Cells separated by a knight's move (in chess) cannot contain the same digit. Digits in a dotted cage sum to the total given in the top left corner of the cage without repeat. Cells separated by a black dot has one digit double or half the other (1:2 ratio). Cells separated by a white dot are consecutive. Not all dots are necessarily given.
