+# Identity model and upstream ownership reconciliation
+
+Implements CFED-WP-0001-T05 from accepted ADR-006 and the federation ledger.
+
+## Reconcile incumbent definitions
+
+```task
+id: INFO-WP-0021-T01
+status: done
+priority: high
+state_hub_task_id: "6b907000-2be8-5dc2-8cc4-442e672bc35b"
+```
+
+Review Delegation/Identifier overlaps against accepted ownership; consolidate
+into identity and retain upstream import anchors. Disambiguate Profile,
+Relationship and assurance dimensions. Record boundary-review.md.
+
+## Author and register the identity model
+
+```task
+id: INFO-WP-0021-T02
+status: done
+priority: high
+state_hub_task_id: "a34f8f3e-70bd-5bf8-90c0-80ad047b067a"
+```
+
+Represent all 23 ledger-assigned concepts and two convenience terms; import
+organization, access and evidence concepts; adapt P1–P13. Register draft 0.1.0
+in canon, infospace, artifact graph and kernel map. Close the Access identity gap.
+
+## Verify ownership and retrieval
+
+```task
+id: INFO-WP-0021-T03
+status: done
+priority: high
+state_hub_task_id: "2ae54fb7-2079-5fbc-b745-eb36a6787fc9"
+```
+
+Check exact ledger coverage, no upstream-owned concept definitions, no duplicate
+Delegation/Identifier definitions, generated surfaces, service checks and source
+preservation. Record project evidence and synchronize native tasks.
+
+## Live continuation
+
+CFED T06 owns CommerceCanon publication; T07 corpus distribution; T08 interface
+cards; T12/T13 social collective and Family work. These remain live records;
+no stable promotion or consumer adoption is claimed by this implementation.
+
+## Verification — 2026-09-05
+
+make check passes: 45 tests, generated consistency, canon and small-saas profile
+validation. Exact ledger coverage: 23 owned concepts plus two convenience terms.
+All 34 protected seed/finished-plan hashes unchanged; links and whitespace pass.
+The exact five-edge model-import component has a documented validation exception
+with regressions for unexpected edges, members, cycles and missing rationale.
