This is a Melon puzzle. (11 – Tapa)
or solve online (using our beta test of Penpa-Edit tools; use tab to shift between shading mode and the composite Yajilin mode where left click marks cells, right click marks dots in cells or X’s on edges, left click+drag draws lines.)
Theme: Logical
Answer String: Enter the length in cells of each of the shaded segments from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma.
Time Standards (highlight to view): Grandmaster = 5:00, Master = 7:45, Expert = 15:30

The logic to solving this puzzle is very intrinsic, I like it. The break in and the steps immediately following it are especially nice.

Wow, that was great. I needed a couple what-ifs, but all of them only try one cell each. And the path is nontrivial. Nice 🙂
Thanks for a wonderful puzzle. Both the connection and the picross logic were rather subtle.
I suppose a little T&E in a couple of places would have shaved a couple of minutes off my time, but doing that to such an elegant construction would have been sacrilegious.
