# Federation interface publication

Native implementation of CFED-WP-0001-T08, authorized by the user's continuation
of the accepted federation plan. Review uses CUST-ADR-006 accepted-1 and the
completed model placements; no governance amendment or domain promotion.

## Publish the interface and reciprocal navigation

```task
id: COMMERCE-WP-0004-T01
status: done
priority: medium
state_hub_task_id: "ef90ef4a-07e7-5e8b-b234-5e4149edef29"
```

Publish [commerce-canon's card](../infospace/interfaces/federation.yaml) with actual imports, available exports,
source authority, maturity and both peer references. Custodian has no domain
semantics. Commerce reviews and preserves the prior Counterparty import pin.

## Verify and publish evidence

```task
id: COMMERCE-WP-0004-T02
status: done
priority: medium
state_hub_task_id: "fcb988b6-77bd-5953-94d0-44b2033d6fd1"
```

Pass schema, reciprocal-edge, ledger ownership, pinned-source and navigation
checks in the project G7 validator. For InfoTechCanon also regenerate discovery
surfaces and run make check. Publish and synchronize this native record.

## Remaining scope

CFED-WP-0001-T09 already owns fleet references; T10 owns demand-driven residual
review. This card creates no runtime adoption, Family authoring or service work.

## Result — 2026-09-06

Published card and reciprocal navigation pass the project G7 validator.
[Consolidated evidence](../../prj-canon-federation/docs/evidence/2026-09-06-interface-cards.md)
records three valid cards, six reciprocal links, unchanged import concepts and
verified historical sources. InfoTechCanon make check passes (46 tests, current
generated surfaces and small-saas proof). No new unowned residual was created;
existing CFED-WP-0001-T09/T10 retain the remaining project scope.
