+# InterfaceCanon derivation boundary
+
+Status: draft review proposal. Review target: interface-canon draft 0.1.1 at
+`1fc82ec6655ed286cea3be284e33d08e7b27edc3`. Acceptance requires the FIAM owner's recorded review.
+
+InterfaceCanon translates FIAM interface terminology into a focused extension to
+InfoTechCanon. FIAM retains authority over standard semantics, Core schemas,
+controlled terms, profiles, policies, reference implementation, and conformance.
+
+The consumer pins FIAM v0.2 Draft 6 at commit
+`135326756913363b098bcdee791628b5e864b8be`, including retained Draft 1 explanation,
+frozen Core schema, and Canon. InterfaceCanon owns its derived presentation and
+cross-canon mappings; it does not issue a new FIAM conformance specification.
+
+Review the definitions and distinctions in interface-canon
+`infospace/models/interface/InterfaceCanonInterfaceModel.md`, especially
+contract versus binding; endpoint versus resource selector; channel versus retained
+resource; shape versus describing artifact versus representation; and
+assertion/source versus derived lens conclusions.
+
+Accept or correct the derivation and record reviewer identity and revision.
+Acceptance concerns fidelity and authority boundaries, not FIAM release promotion,
+consumer runtime conformance, or stable InterfaceCanon publication. The FIAM draft
+and its historical package layout remain unchanged by this proposal.
