REFERENCE SCENARIO · IMPLEMENTATION-GRADERS-06 — Customs verifies product, declaration and DPP status
This scenario connects a user action to state, authority, policy, evidence and integration boundaries. It is a reference model; legal or regulatory decisions remain with the authoritative party for each data domain.
Actors / systemsCustoms Officer; Regulator/Customs Portal; declarant/Economic Operator; external Customs and DPP Registry systems.PreconditionsCustoms authority session/mandate is valid; declaration/product identifier is available; external sources are reachable or freshness is known.TriggerA customs officer opens a shipment/product verification task.
End-to-end flowMatch declaration to product identifier → resolve aliases → authenticate/authorise customs purpose → compose restricted authority view → verify registration/DPP status → compare declaration and governed product facts → inspect provenance/evidence → record decision support and authoritative hold/release reference.State modelVerification Case Open → Checked → Decision Recorded/Closed. Customs hold/release remains an authoritative external action, not a local TTID state pretending to be customs.Authority boundaryCustoms and relevant registries remain authoritative. Trusted ThingID resolves, composes, correlates and records evidence.
Policy / disclosureCustoms officer identity, legal mandate, purpose, case context, assurance and restricted-field disclosure.EvidenceResolution/correlation trace, source freshness, viewed facts, discrepancy record, external response/receipt, policy decision and audit.API / event / connectorResolver; DPP/status read; search; evidence; Customs/Registry connectors; reconciliation events.
Failure / retry / reconciliation
Registry timeout → show unavailable/freshness state; declaration mismatch → surface discrepancy; unknown external result → reconcile; never infer hold/release locally.
