The namespace a bare principal-id string belongs to.
global — account-global (comparable across every org-level context)
project — scoped to ONE project; which project is not in the string,
it comes from context (for stored engine values: the anchor resource
the document lives in)
robot — a token principal with one universal id (never needs mapping)
sentinel — <anonymous> / <system>, never a person
unknown — unclassifiable; treat as unresolvable and surface it
