Bookmarks

Bookmarks never federate -- see the Activities: Create -> Bookmark docs. To broadcast a URL to your audience, post a Link-type Post instead.

GET /bookmarks

makeCollection, viewer-scoped via buildVisibilityQuery.

Root-level only

This only returns bookmarks/folders where parentFolder is unset (i.e. the top level). Walking into a specific folder's contents is only exposed via GET /users/:id/bookmarks?parentFolder=<id> -- this asymmetry is deliberate, to prevent a folder-visibility-inheritance bypass (see below).

GET /bookmarks/:id

Via makeGetById(), but with a custom canView (canSeeBookmark) that additionally requires the entire ancestor folder chain to be visible. A @public bookmark nested inside a private folder is still hidden from non-owners -- folder visibility isn't just a UI grouping, it's enforced at the read layer.
