Has this to say about WikiJS:

Can be linked to a Git repo and do round trip, but the database is the main DB, with sync to/from Git being done at intervals via single committer ID. That said, it is “Docker ready” using NodeJS and is actively maintained.

Which is not quite true. The DB is essentially a cache. The single committer is true.

My notes:

• [[Gollum]] -- not really setup for differential access without runing a whole SSO server
• [[Realms]] -- domain is dead, last code update 2018
• [[DokuWiki]] -- git backed plugin is 5 years last update https://github.com/woolfg/dokuwiki-plugin-gitbacked, still might be worth trying
• [[Jingo]] -- https://github.com/claudioc/jingo -- worth checking, although very basic auth
