Reversion to the Mean (Regression zur Mitte)

My idea was to make the killers as subtle as possible, since the average would be 5 a priori. I hope you enjoy it! Not all the thermometers are strictly necessary, but they make the path smoother.

Here is a harder version with the same solution but shorter thermometers. I think this keeps the path closer to my intended logic. I wish I had posted this version in the first place... sorry, I'm a novice setter, and I need to check more carefully for logic bypasses.
Solution code: row 1 followed by row 2 (18 digits total)

Very cool. Even after wrapping my head around how many hidden 10s and 15s there were and how they interacted, it still took me a while to break through. I really enjoyed finding the trick.

Hint: although this puzzle doesn't have a magic square, you may find it useful to keep a magic square handy as a "map" of what triples sum to 15, and how odd and even digits participate in or block these triples.
