| FIAM evidenceRecord | Map to ITC-EVID Evidence plus Evidence Source | FIAM evidenceRecord is support metadata with source, mode and confidence. ITC Evidence is an assertion drawn for a question; source container is separately identified. This is not a one-to-one rename. |
| Evidence score | ITC-EVID Evidence strength | A FIAM Lens computes a policy-specific heuristic; confidence and support scores are not universal truth probabilities. |
| Artifact | FIAM describing/implementing artifact role | It may serve as ITC Evidence Source when addressable and versioned; the artifact is not the assertion drawn from it. |
| Artifact | FIAM describing/implementing artifact role | It may serve as ITC Evidence Source when addressable and versioned/captured where mutable; the Evidence assertion must state its explicit interest. Implementing a contract does not automatically make an artifact a KnowledgeArtifact. |

The initial review is complete. External federation acceptance and evidence of
consumer adoption remain in INTERFACE-WP-0004; publication stays draft.
## Owner-review clarifications
Network Port covers physical/device ports as well as protocol-level transport
ports; the TCP example is illustrative, not exhaustive. Resource/shape mappings
establish neither universal subtyping nor exact equivalence. Describing artifacts
may qualify as KnowledgeArtifact; implementation artifacts do not qualify merely
because they implement a contract. Evidence Source is the addressable container,
with version/capture where mutable; Evidence states the assertion and explicit
interest. These clarifications preserve the imported source meanings.
Acceptance scope and source revisions are recorded in the
[acceptance report](../reviews/acceptance/README.md). Earlier owner reviews target
0.1.1; the local clarification revision is draft 0.1.2.
