+# Open Questions
+
+Status: draft. These questions are intentionally non-secret and
+implementation-neutral.
+
+## Canon Questions
+
+- Should Realm stay a Scope specialization, or does it need its own canonical
+  concept because of issuer and federation semantics?
+- Should Customer Account become a canonical concept, or should customer
+  account records remain downstream commercial modeling?
+- Should Team be modeled as a Group, Organization Unit, Community, or a
+  separate specialization?
+- Should Legal Entity be a specialization of Organization or a relationship
+  between an Organization and a legal system?
+- What fields are mandatory for every Relationship versus only for sensitive
+  relationships such as delegation, representation, and synonymity?
+
+## Synonymity Questions
+
+- Which confidence vocabulary should be used for weak matches?
+- What is the minimum evidence model for strong account links?
+- How should revocation or expiry of a synonymity assertion affect downstream
+  caches?
+- How should privacy-limited links be represented so accidental broadening is
+  visible during review?
+
+## Corpus Questions
+
+- Which source notes should be backfilled first: SCIM and LDAP for record
+  semantics, OIDC and SAML for subject semantics, or OpenFGA and Cedar for
+  authorization projections?
+- How much product-specific detail belongs in source notes versus downstream
+  recommendations?
+- What citation format should the repo use once source notes are populated?
