Two more preparation puzzles. This one is probably my favorite take on the “worm rule”, exhibited here for rows and columns without clues. While constructing, it felt like there might be more potential in the type if the order of stalagtites wasn’t given. (The clues here are all 3s and 4s, in case you have trouble deciphering the typesetting.)

Rules Fill the grid with numbers 1 to 5 so that they don’t repeat in rows or columns. The hints around the grid denote all the increasing or decreasing sequences longer than 2 in the given row/column in the correct order. The sequence is increasing from the tip of the sign.
