Question regarding the books in permanently unfinished status

[Beliar]

Say, there is a situation where an author has published 4 novellas in the series and half of the fifth one, before their death. As the novellas were published online as web-novels they are readily available to read.
The first four novels should obviously use full integers as part of the series (#1, #2 and so on), but what happens with the fifth one. Should it be added as #5 even in the halfway finished status? Or a fraction, like #4.5 should be used? An even smaller number, like #4.1? Or maybe it shouldn't be added at all?
As the author in question was very prolific, there are not one but a few unfinished series left by her, neither of which are on GR yet, thus the question.

I believe unfinished works are not to be on GR at all.

Unless they were officially published after the author's death.

[Scott]

Well, yeah.
This is an online thing though.

I see, then probably just a note in the description of the forth book that there is an unfinished fifth book.

Anyway, I have another tangentially related question. The same author has a short series with one novella and three short stories that precede it. How would the numbering look in such a case?

I would suggest
- if novella is significantly longer than short stories:
#0.1, #0.2, and #0.3 for short stories and #1 for the novella

- if they are all similar length:
#1, #2, #3 and #4
