 # Downstream Recommendations
 
-Status: draft. Originally updated after IDENTITY-WP-0003 corpus backfill.
-Source references refreshed 2026-09-06 under CFED-WP-0001-T09. The implementation
-ideas below remain recommendations and do not certify consumer adoption.
+Status: draft. Updated after IDENTITY-WP-0003 corpus backfill. Implementation
+ideas derived from the canon; no implementation in this repository.
 
 ## Recommended Consumption Pattern
 
-Downstream repositories should reference [InfoTechCanon](../info-tech-canon/infospace/interfaces/federation.yaml)
-for identity, organization, access and shared evidence concepts, and
-[CommerceCanon](infospace/interfaces/federation.yaml) for counterparty and
-commercial-relationship semantics.
+Downstream repositories should consume identity-canon as a conceptual reference.
 Map schemas, APIs, CLI commands, UI labels, and authorization policies to
 canonical terms. Do not depend on this repository as a runtime package unless a
 later explicit package is extracted.
