+# Canon federation interface
+
+The [interface card](federation.yaml) publishes this canon's federation boundary
+under [accepted ADR-006](../../../the-custodian/canon/architecture/adr-006-canon-federation-concept-ownership.md).
+
+- [info-tech-canon interface](../../../info-tech-canon/infospace/interfaces/federation.yaml)
+- [the-custodian interface](../../../the-custodian/canon/interfaces/federation.yaml)
+
+Each export names its source document and current maturity. Imports identify
+actual dependencies; reciprocal navigation does not imply reciprocal semantic
+imports. Custodian supplies ecosystem governance, InfoTechCanon information-
+processing semantics, and CommerceCanon commercial semantics. Family remains
+seeded, not authored. The card scope is this federation, not every repo artifact.
+
+Reproduce G7 from the adjacent project checkout:

+  ownership_assignment: prj-canon-federation/ledger/concept-ownership.json
+  definitions: exporting canon model documents; seed areas carry no authored domain model
+mapping_rules:
+- Import a concept from its declared owner; do not copy a definition as a competing local root.
+- Identifier stays itc-ident; Registry Identifier and Proxy Commercial Identifier are Commerce specializations.
+- Evidence assertions and Evidence Source containers stay distinct under itc-evid.
+- Identity Assurance Level, governance AssuranceCase/AssuranceConclusion, and Counterparty Assurance Gradient
+  stay distinct.
+- Family is a separate seed; Community and Household are itc-org draft social collectives.
+known_deviations:
+- This card uses the existing JSON Schema string consumer / array canon_surfaces shape; richer Core section
+  24 fields are additive.
+- Exports describe availability, not proof of adoption. No reverse Commerce domain import by InfoTechCanon
+  or Custodian is asserted.
+- Custodian governs both domain canons but owns none of their domain semantics.
+expectations:
+- Validate reciprocal cards and pinned sources with prj-canon-federation/tools/validate_interfaces.py.
+- Review changed source versions explicitly and retain earlier import manifests.
+- Fleet reference acceptance remains CFED-WP-0001-T09; demand-driven residuals remain T10.
