I've been meaning to explore wraparound grids with internal/external clues ever since setting this puzzle. I'm very pleased with the result, and hope you will have as much fun solving it as I did setting it. I got a range of feedback regarding difficulty estimation, and 4-star estimate definitely assumes familiarity and comfort with the standard full rank constraint.

On that note, thanks to Manta-Ray, ChinStrap, and kingoffries for testing and rule advice.

Rules:

Sudoku: Place the digits 1-9 once each in every row, column, and box.

Thermometers: Digits along a thermometer strictly increase from the bulb end.

Klein Bottle Grid: The edges of the grid wrap around, such that the left edge wraps to the right. The top and bottom also connect, but have undergone a twist such that the left end of the top wraps to the right end of the bottom. This is reflected in the coloring.

Full Rank, You-can't-escape-the-grid edition: Each row and column represents two nine digit numbers, one when read forwards and the other when read backwards. A value in a pointing pill represents the rank of the nine digit number that begins with the cell on the other side of grid border that the pill points towards. Rank 1 has the smallest value and Rank 36 the largest. There are no tied ranks. Two-cell pills are two digit numbers, read in Western reading order (so the left/top digit is the tens digit, and the right/bottom is the units digit).

Clues outside the grid are duplicates of the clues inside the grid, to help keep track of the twisted grid layout.
