The Sudoku Variant museum has closed for the day, but a Naughty Negative Snake still wants to check out the exhibits.
It breaks into the museum through the central skylight (R5C5) and wants to quickly visit every exhibit (Box) exactly once before making a hasty retreat from the museum through one of the 4 exits (Corners).

The snake consists of a single path of orthogonally connected cells that never touches itself orthogonally (diagonally is fine).
Adjacent digits along the snake must not be consecutive or in a 2:1 ratio, and must not sum to 5 or 10.

Solve the sudoku such that there exists a unique path for the snake through the museum.

All standard variant rules apply.
