Logic Masters Deutschland e.V.

This is my entry for turn 6 of season 1 of The Skunkworks League, hosted by damasosos92. In this round, the prompt was to create a puzzle in a 9x9 grid that used the winning IDs of the previous rounds (3, 6, 17, 17, 34, 45) as the only numerical clues.
Estimated difficulty is between 2 and 3 stars.

Rules:
Normal Sudoku rules apply.

Digits separated by a white dot are consecutive. Not all possible dots are necessarily given.

Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.

The loop acts as an entropic line. Each set of three adjacent digits along the loop must be one low [123], one medium [456], and one high digit [789].

Clues outside the grid give the sum of all digits on the loop in their respective row or column. Additionally, the digit in the first cell on the loop seen by the clue in its row/column is the total number of loop cells in that row/column.
