I have hypothes.is installed inside docker container locally. No serious
protection is required in such case (at least, no more than one would
use to protect private files from dangerous software like browsers).

Public annotations would better be just exported to a public server
(automatically or not).

I am not sure how it is different from using hypothes.is for the same
purpose. Note that hypothes.is uses pdf fingerprinting, so you don't
even need to store pdf on server side. If user can open the pdf
(obtained from you directly, for example), hypothes.is will
automatically show the up-to-date annotations shared via public
hypothes.is instance for that particular user.

hypothes.is uses OAuth mechanism with fine-grained control over the
access to various annotations. Also, one can run it inside encrypted
docker container (or even inside virtual machine) reducing the risk if
server is compromised.
