Regional Heatwave

Normal sudoku rules apply.
Classic fog of war:
- Some of the grid is covered in fog;
- Entering a correct digit will clear all fog in that digits immediate neighbourhood.
Regionometers:
- Box borders divide lines into segments, whose sums must strictly increase from one end to the other;
- No line has multiple segments in the same box;
- Different lines are different colours;
- Lines may not branch or share cells with other lines;
- Lines may cross diagonally at cell vertices.
N.B. Lines have been made thin enough such that it is not possible to assume that diagonal line segments do or do not exist based on a few pixels of colour in the corner of a non-fogged cell (e.g. r5c1-r6c2 may be a line segment even though it doesn't appear in the top corner of r6c1).
Lösungscode: Row 9 (bottom row), left to right

I rated this 2/5 difficulty.
Really great FoW puzzle! I really liked how the solve path was clearly well thought-out & planned, and how the puzzle really utilized every aspect of the rule, right up until the very end.
This puzzle was very smooth from start to finish, and was honestly quite approachable while remaining very engaging. I think the overall difficulty was on the harder end of 2*, but not quite at the 3* difficulty level. Every step was totally fair, and my solve time also falls in the range of other 2* puzzles.
Great puzzle, thanks for sharing!

Very nice puzzle, I always forget to never write a number in a fog sudoku even to visualize the next few steps' working. I did that by mistake in one cell, which gave me some info that I didn't earn properly. But I refused to use that info until I derived with proper logic again.
Enjoyed the puzzle thoroughly nevertheless

Loved this. Got stuck because i drew my own lines and made a horrible assumption.

Fun! It definitely stretched my mind for what was hiding back there behind the fog. Beautiful work!

Super fun to solve, quite approachable in the end but certainly not easy. Everything flowed really well.

Amazing puzzle with a beautiful break-in! And surprisingly approachable - especially for a TPP-puzzle… :-)
Thank you very much for creating and sharing this lovely gem.

I am afraid I don't fully understand 1 part of the rules: what does strictly increase mean? 1<2<3 or 1<5<9?

for any "noobs" reading this:
ignore the stated difficulty. it's wrong. this puzzle is "approachable", and worthy.
all you need is
- basic sudoku (there is a "pivot", but you can find that without knowing what it is)
- understanding the concept of >
- ability to add small numbers
- knowing basic cage combinations
- basic logic

Amazing construction, challenging but smooth, thank you for this gem!

very natural solve! I especially liked how the final line serves only to remove equality as an option

What a great puzzle! Had a very smooth beginning with a tricky middle section. Thanks for sharing!

What a puzzle! After the first 5 minutes I thought I'd just whip through this and then it took me through a 3* roller coaster. I loved the final disambiguation!

What a phenomenal puzzle. This has such a casual brilliance to it, the kind of puzzle that feels like it coalesced fully formed out of the ether... almost (or maybe completely?) divine.

Very cool and fun puzzle, thanks!
