Memoria

This is a puzzle I made in 2023 that I never published but always really liked. It was originally part of a larger pack of puzzles I made so I didn't immediately publish it, but it's been long enough that I think it makes sense to post here and have this puzzle seen by a more diverse field of solvers. Hopefully you like it!

Rules:

1. All digits 1-9 must appear exactly once each in every row, column, and 9-cell orthogonally connected region (Irregular Sudoku)

2. Cells separated by a black dot have a ratio of 1:3. Cells separated by a white dot have a difference of 5. Not all dots are necessarily given, so no negative constraint (Difference/Ratio, this specific variety sometimes called Gamma and Epsilon)
