Place tetrominoes into the grid so that they obey the rules of LITS (aside from the region constraint). Tapa clues indicate each individual tetromino in the surrounding squares.

In addition to the usual rules for Nurikabe, the grid has been divided into four quadrants. In each quadrant, a different rule applies:
Standard Nurikabe: Each region contains a single number indicating the size of its region. Araf Nurikabe: Each region contains two numbers. The size of each region is strictly between its two numbers. Pairs Nurikabe: Each region contains two numbers. The size of each region is the sum of its two numbers. Either-Or Nurikabe: Each region contains two numbers. The size of each region is one of the two numbers; the other should be ignored.
If there are two clues in the same region, they must be from the same quadrant. Which quadrant corresponds to which rule is left to the solver to determine.

In addition to the usual rules of Statue Park, one clue in each row and column is mislabelled. If it is black, then it is not contained in one of the shapes. If it is white, then it is contained in one of the shapes.
This is a quartet puzzle of Maximal Archipelago, Yajisan-Kazusan, Heyawake, and Smullyanic Dynasty.

In this puzzle, the grid is divided into four sections. Maximal Archipelago in the top left, Yajisan-Kazusan in the top right, Heyawake in the bottom left, and Smullyanic Dynasty in the bottom right. Together they form a large grid, and all connectivity and adjacency rules apply across the whole. In addition, each number has been replaced by a letter. Different letters refer to different numbers, with the same cipher being used throughout the whole puzzle.
Clues in the Maximal Archipelago only refer to squares in that corner. The maximality constraint also only applies to that corner, meaning that in the final solution of the puzzle, it should not be possible to add a black square to the Maximal Archipelago without breaking connectivity or adjacency.
In the Heyawake, only the borders within the grid matter for the border rule. The borders between the four grids are not used for the Heyawake constraint.
In the Smullyanic Dynasty, clues look at the squares in adjacent grids.
