# Shared evidence model and governance import boundary

Implements CFED-WP-0001-T11 under accepted CUST-ADR-006 R3/R5/R7. The existing
INFO-WP-0019 maintenance work remains separately owned. This plan uses the local
workplan convention's INFO prefix. Registration retains model status draft.

## Author the shared pair and worked examples

```task
id: INFO-WP-0020-T01
status: done
priority: high
state_hub_task_id: "db42df00-cf84-57a7-81a4-a5fd998717bc"
```

Own Evidence, Evidence Source, Adjudication Outcome and general evidence strength
in itc-evid. Separate assertions from containers, make capture interest explicit,
and show invoice/XML integrity and adjudication cases without claiming legal or
financial effects. Preserve the donor corpus and original seed provenance.

## Transfer the live ownership boundary and register

```task
id: INFO-WP-0020-T02
status: done
priority: high
state_hub_task_id: "00444404-1963-568d-a8e0-631adb607073"
```

Replace governance Evidence ownership with imports, update its chain pattern,
register the new model in canon and service catalogs and kernel map, and correct
live direct consumer ownership assertions. Preserve EvidenceBasis catalog
identifiers and behavior as the existing quantity-origin application.

## Verify retrieval, ownership and generated surfaces

```task
id: INFO-WP-0020-T03
status: done
priority: high
state_hub_task_id: "5b675961-de3c-57d8-a102-c2f0e9ea55e6"
```

Refresh indexes/briefs; run repository checks and focused evidence-boundary
regressions. Verify seed, catalog and finished workplan hashes unchanged.
Record evidence and reconcile native/project workplans.

## Live continuation

CFED-WP-0001-T05/T06 own identity/commerce migration imports; T07 owns research
corpus distribution; T08 owns reciprocal interface cards. These remain live in
prj-canon-federation. No consumer adoption or stable model promotion is claimed.

## Verification — 2026-09-05

make check passes: 38 tests, generated-artifact consistency, canon validation
and small-saas profile validation. git diff --check passes. All 34 protected
seed/catalog/historical plan hashes remain unchanged. The federation donor ledger
verifies its pinned source with zero unowned or multiply owned concepts.
