Foggy Paths

Rules:

1. Fog: Some cells are covered with fog. When a correct digit is placed into the grid, the fog will clear, revealing additional cells of the puzzle.

2. Row / Column: Each row and column will contain digits 1-9 exactly once. Additionally, one cell in each row and column is empty (marked in black).

3. Lines: Adjacent digits on the red oscillator line(s) alternate between high (6789) and low (1234). Adjacent digits on the blue parity line(s) alternate between odd and even. Neither type of line enters an empty cell.

4. Positive diagonals: Each positive diagonal (marked with arrows) contain digit 5 at most once.

5. Dots: Digits separated by a green dot have the same mod3 value (i.e., 1,4,7, or 2,5,8, or 3,6,9). Of the digits separated by a black dot, one is two times the other. Not all dots are given.
