Rules:
Normal sudoku rules apply.
Scrin: Place several non-overlapping rectangles into the grid, each comprised of orthogonally connected cells (or a single cell). Rectangles cannot share edges. A rectangle contains at most one circle, and a digit in a circle equals the size of that rectangle. (Every circle must be in a rectangle.) The rectangles must all form a single loop through diagonal connections, with no branches.
Whispers: Orthogonally adjacent cells within a rectangle must differ by 5 or more.
For those unfamiliar with scrin, here is a link to an explanation/example on puzzlink.

Solution code: Row 1 (left to right, 9 digits)

Nice construction plesant solve.

Took longer than I'd like to admit to figure out the ruleset, but like everyone one else once it did it flowed beautifly!

An exemplary hybrid, the added whispers constraint added just the amount of tension needed in the puzzle. Not too tricky, but very enjoyable! :)

I hadn't heard of scrin before solving this puzzle, and this hybrid was an excellent introduction to the genre!

Very interesting hybrid, very well executed - who can ask for more? Thank you so much for sharing.

Nice puzzle. Took me a while to understand there’s no negative constraint on creating rectangles that aren’t in the loop, and that non-loop rectangles can share an edge with loop rectangles. Interesting ruleset.

Great pencil variant !

I had to read the rules several times and look up scrin puzzles, but once I got my head around it, a very nice puzzle with a rule set that was simple and I haven't seen before.
It would have been helpful for me to see an example and my brain somewhat misfired thinking that all rectangles would have a circle in them, but once I realized that was impossible it was a nice smooth solve.

Fun as always, mathpesto!
It would be helpful if you could put a little illustration of what is allowed with the rectangles: what a correct loop looks like vs. what a branch looks like. The rules took some figuring out.
