A durable, replayable citation is persisted only on an explicit cite: GET /api/v1/entries/{id-or-slug}/evidence, or the MCP cite_query tool. Both are entry-scoped, because evidence_manifests is entry-shaped; a domain answer spanning several sources has no single entry and cannot be persisted through that path."}}
