Rules:

Normal sudoku rules apply.

Digits in cages cannot repeat and must sum to the clue in the corner.

Digits separated by the V must sum to 5.

Digits separated by a white dot must be consecutive, and digits separated by a black dot must be in a 1:2 ratio (one digit is double the other).

Not all Vs or dots are necessarily given.

Draw a one-cell-wide loop of orthogonally connected cells that must pass through every cell in every cage without visiting any cage more than once. The loop cannot touch itself orthogonally but may touch itself diagonally. The loop acts as a polarity line, meaning adjacent digits must alternate between low (1, 2, 3, 4) and high (6, 7, 8, 9).
