One note about the auto-answer checking is that it looks like it only works for specific notations?
E.g. for nanro I typically solve without numbers (just shading), which the solver doesn’t seem to accept.
We are noting on the Rules option on the Penpa pages what each style is checking for. Checking for the presence/absence of lots of different things is difficult when also being flexible with puzzle design rules, so that is why we are choosing one option for each style. For Nanro there will be a lot of variety in solver notation; for example, I expect other solvers will use lines instead of shading (to trace connectivity easier) and possibly further modes like shading on vs off cells in different colors.
If there is enough support for shading vs. numbers for a style like Nanro, we can change what is checked in future posts.
