Major thanks to tnop62830, who helped me fix the ruleset for this puzzle extensively.

Chaos Construction: Place the digits 1-9 in every row, column, and disjointed region, to be determined by the solver. Regions never share cells and do not need to connect orthogonally or diagonally.

Chess Regions: Each region represents the moves of a chess piece or pawn. Each piece has made a set of 8 legal, consecutive moves, starting on a square marked (on the edge) by its respective notation.

Pawns: Pawns start on either rank 2 or 8, may move two spaces on their first move, and may always move as though they captured. Pawn promotions occur on the last rank away from their starting space (1 or 9 respectively). All pawn promotions are given, and any remaining moves will be of the piece promoted to.

Check: A king is in check if the digit N in its region is seen by N in another chess piece's region, according to that piece's type. If N is a 9, it is checkmate.

Castle: Castling may occur from the starting square of a king and a rook. The king moves two spaces in the direction of the castle, and the rook moves to the other side of the king.

Notation: The given list of chess notation are moves that have occurred on the grid, in no particular order.

Ndb4 implies that two knight regions can see b4, but the move occurs from the d file.

Lines: Each given line represents a chess move by one of the 9 chess regions, starting on one end of the line and ending at the other. Whichever piece makes that particular chess move, other moves by the same type of piece must not land on or cross that line, except for the crossing given lines. (You may land on the starting square.)

Digits must differ by 5 on all green AND lavender lines.
Digits equidistant from the center of the lavender line must sum to the same number.
On the teal line, every set of three sequential digits contains one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}.
On a peach line, every set of three sequential digits contains one digit from {1,2,3}, one from {4,5,6}, and one from {7,8,9}.
On the gold line, no two digits can repeat or be consecutive.
The purple line is a consecutive set of numbers in any order.
