Any updates?

I took a look at this now; apparently it seems that pydoctor does not recognize properties defined in classes implemented in C code automatically as it relies on parsing the Python source of the class, which is not accessible in this case. I'll check whether there's a way to tell PyDoctor the list of properties explicitly.

Unfortunately this seems to be an issue with pydoctor. pydoctor uses obj.__dict__.items() to iterate over all the members of a class to find out which ones are to be documented. The items that are missing from the documentation never appear in obj.__dict__, and even adding them manually to the class docstring with @ivar does not seem to help - the list of items to be documented in a class is still decided by obj.__dict__.items().

The only option that we have right now (without patching pydoctor) would be to just document the missing attributes in the class docstring in plain text. They would not appear in the list of class members but at least they would be mentioned in the HTML docs. Would that be OK for you?

Yes, that would be an improvement over the current situation, where the functions are not discoverable from the documentation alone so the reader would not know what he is missing.
