What is the purpose of the ui.content subproject? how do you prevent it from overwriting author generated content? about aem-project-archetype

In my (limited) experience with managing content, this can be considered a "seed" package, used to generate the filters for the content structure. You'll only deploy this once on a staging/production environment, otherwise - as you pointed out - will overwrite content.

However, you'll use this lots of times on a development environment, and also to replicate changes from author to publish in staging/prod and also to bring content from prod to staging if needed.
