This puzzle is a mix between Japanese Sums and Cave.

Rules:

1. Place the digits 1-9 in every row and column exactly once.

2. The filled cells/empty cells form a valid cave solution. Circles indicate cells which are valid cave clues. Not all circles are necessarily given.

3. Outside clues are Japanese Sums clues, where "?" can replace any digit 1-9. Clues in the same row or column are separated by at least one empty cell. "?*" encodes the existence of exactly one Japanese sum clue, and "..." encodes the existence of an arbitrary number of Japanese sum clues (which may be none at all).

Penpa+ link. Enjoy!

An 8x8 example with the digits 1-5 for those not keen on parsing the above:

Lösungscode: Row 10, Column 4, with 'X' in place of empty cells.

What a corker, thanks. On several occasions I was stumped and struggling to see how I could progress, but something always showed itself eventually.

Lovely puzzle! The ending was quite thrilling due to the fact that I had made a very silly mistake in the very beginning, that luckily turned out to be easily fixable. :D

Unexpected and joyful structure deductions. Never seen anything like this!

Loved it ! Having solved some of your lastest harder puzzles, this one felt quite easier. The final disambiguation of the "almost deadly" pattern was very naughty, and it came as a very fun endpoint !

I'm assuming ?* denotes that the Japanese sum clue corresponds to exactly one digit in the grid? Is that a correct reading of the rule? The usage of "clue" here confused me but that might just be my inexperience.

-----

Hi @kjholt, that is not a correct interpretation of "?*". Apologies for the lack of rigor in the definition, but it is essentially saying that the clue could have either a single or double digit total. If it was given to be just a single digit total "?" would be written, and for double digit, "??".

Here's a quick image illustration I made with sums for a row: https://imgur.com/a/GG0LLA5 (obviously not valid, as no circle clue can be empty, but I think you can get the point here)

Hope this helps :)

Oh that makes sense! Thank you for your prompt reply; I just got to a spot in the break-in where it was clear I was incorrect so I came back here :) --kjholt

Thanks for this puzzle. the wording confused at first but I finally got the ?, ... and * where they were needed. 5*

Really cool hybrid idea and a very fun solve!

Absolutely brutal and amazing puzzle! Solving this on my phone was a scary experience, but well worth the trouble.

And I'd recommend first to solve the example, it's also a very good puzzle and helps a lot to get familiar with the rules.

Edited a line of the rules as per polar and Dandelo's suggestion

But I agree with polar that the rules (leftmost/rightmost etc.) are not correct. I've read it as intended, and the example also gives a hint, but the actual text allows to switch the inner groups, IMO.

both of you make a good point. that section just serves to confuse, so i'll omit it

Aargh, I still had the old solution code description in a tab...

Great puzzle.
