Genealogy
Answer a current two-node relation
Requires company admin access and members.view aliases. Both nodes must be visible in the same company and tree. Unavailable nodes return 404 rather than false. Strict ancestry excludes self; subtree membership includes self. root_of includes the root itself. sibling_of follows the common-parent convention, including self and separate roots; sibling set reads separately exclude self. Historical, paging, expansion, and body selectors are not accepted. Reads do not require move admission.
