lgtm, a couple of questions/remarks inline.

swh/loader/git/converters.py
42

I have a hard time reading this ^ chunk (line 37 to 45).

Does that mean something like, all functions decorated with check_ids must respect the signature (self, obj: ShaFile, log=None) -> _THashable when called upon?

(That plus what the decorator actually does, checking for mismatched checksums).

Now that i said it, it actually makes sense to me...

swh/loader/git/tests/test_converters.py
116–120

why not ^ ?

or even simpler:

def sha(self):
    return lambda: self._sha

?

why not make check_id return the object?
so you can write:

return check_id(Directory(id=tree.sha().digest(), entries=tuple(entries),))
