As in, a clear way to detect whether a given file is lossy or lossless?
I was thinking that too, but on the other hand, even a lossless file can't guarantee that its contents aren't the result of going through a lossy intermediate format, such as a screenshot created from a JPEG.

I meant like a filename convention, and tags in the file itself.
There is some sort of tag, jxlinfo can tell you if a file is "lossy" or "(possibly) lossless".
Presumably you can look at the file and tell which mode is used, though why would you care to know from the filename?
