      "Pairwise into shared graphs: an entity projected into a shared graph presents a pairwise identifier, never a global anchor — semantic interop cannot become a correlation identifier.",
      "Typed principals: principalKind (human | agent | service) is bound into the signed source credential by its issuing authority; an Agent can never project as a Person.",
