Rules:
Schrödinger Cells: Place the digits 0–9 once in every row, column, and box. To allow this, an “S-cell” appears once per box, which contains two digits simultaneously.
Lines: Digits along a gray line sum to a multiple of 10. Digits may repeat on a line if allowed by other rules.
Tapa: Shade some cells so that all shaded cells form one orthogonally connected area and no 2x2 region is entirely shaded. Circles cannot be shaded, and each digit in a circle corresponds to a block of consecutive shaded cells in the (up to) eight cells surrounding the circle. An S-cell gives two clues while a regular cell gives one. If a circle contains two clues, the corresponding blocks of shaded cells must be separated by at least one unshaded cell, and blocks can appear in either order. (For example, if a circle contains just a 4, there is exactly one block of four shaded cells while the rest are unshaded. If a circle contains a 2 and 3, there is exactly one block of two shaded cells and one separate block of three shaded cells; these blocks are separated by at least one unshaded cell.) A “0” can be placed in a circle only if it is the circle’s single clue.

Phew! Having very little experience with either Tapa or S-Cells made it easy to overlook options several times along the way, but sticking it out was immensely rewarding. Thanks for an excellent puzzle (with an equally excellent title) :D

Idk why but the concept of a "naked double" is hilarious to me. Thanks for this!

Awesome puzzle, but it was a mistake to tackle it at 2 AM :D

It took me awhile to get my head around this puzzle, but I'm happy I didn't skip it.
S-cells and Tapa combine so well together, and the third layer of the lines tied it all to make a confusing at times, yet very interesting and intriguing solve.
Thank you, mathpesto! ^_^

I was a bit reluctant to try and get into this puzzle because it seemed so hard, but I love puzzles with Schrödinger cells and decided to give it a go, and accept the risk of being sad if I were to fail. So glad I made that decision. What a wonderful puzzle to solve! Thanks!
