• Normal Sudoku rules apply.
• Entropy: Every 2x2 square of cells must contain a low digit (1,2,3), middle digit (4,5,6) and high digit (7,8,9).
• A gold cell contains its position within its row, column or box (in normal reading order).
For example the gold cell R4C8 contains either 8 (position in row), 4 (position in column) or 2 (position in box).
• All possible gold cells are given.
For example the white cell R9C1 does NOT contain 1 (position in row), 9 (position in column) or 7 (position in box).
Solution code: row one

Great puzzle! The moment when the fact just how restrictive one of the rules is clicked was quite magical, still took me quite a while tho!
