Only when you narrow the scope can questions about whether PUT is a
replace or update become meaningful.  E.g. If I PUT a blog post that is
missing a summary, what does that mean in the context of a blog server.

It does mean that the summary is missing. The server

- can reject the request, or
- can accept the request and leave the summary empty, or
- it can try to extract a summary from the entry.
It can not simply re-use whatever the summary was before the PUT request. What would be the point of doing that?
