195? 519? 951?

Normal Sudoku rules apply. Orange lines are entropic lines; any set of three consecutive digits along a line must include one low (1-3), one medium (4-6), and one high (7-9) digit. 159 rules apply: Each digit in column 1 indicates the position of the 1 in the same row (for instance, if row 5 column 1 is a 7, row 5 column 7 is a 1). The same is true of columns 5 and 9 for the digits 5 and 9, respectively.
My contribution to the recent Layers of Entropy pack of entropic lines puzzles. If you enjoy entropic lines, feel free to check out the rest of the pack at this link, or archived on the CTC Discord at #7590.
It's also the latest entry in my Empty 159 series; previous puzzles featured thermo, German Whispers, Renban, Lockout Lines, X pairs, between lines, and difference dots.
Solution code: Row 1 followed by column 6, no spaces

Unexpectedly difficult for such a combination of variants. Entropy feels like a trivial extension of 159, but the interactions here are surprisingly original.

Yet another incredibly brilliant puzzle again, I'm so shocked at how the interactions work in this puzzle, really cool stuff! ;)

Been waiting for a 159/entropy puzzle (low mid high theme). The rating is intimidating but lets see how it goes

I believe even the worst of constraints, if utilized masterfully, can create a great puzzle. This puzzle exemplifies that principle.

159 and entropy lines work surprisingly well together. Lovely puzzle. :)

Very nicely put together, but certainly not a pushover. This was a far more interesting combination of constraints that I originally thought. Nicely done!

Those contsraints do really play well together in this puzzle!

Beautiful! Loved the interactions and especially how some things were disambiguated. Thanks!
