REFERENCE SCENARIO · IMPLEMENTATION-GRADERS-03 — Ownership / custody transfer with evidence-backed relationships
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 / systemsCurrent owner/custodian; receiving party; Owner App; relationship/claim service; identity and mandate services.PreconditionsBoth parties can be identified to the assurance required by policy; the current relationship claim is active and transferable.TriggerAn authorised party initiates a transfer or custody handoff.
End-to-end flowResolve thing → verify current relationship → authenticate parties → validate mandate/policy → create transfer intent → recipient accepts where required → close/supersede prior relationship → issue new claim → record evidence.State modelRelationship claim Active(A) → Transfer Pending → Superseded/Closed; new relationship claim Pending → Active. DPP lifecycle remains separate.Authority boundaryTrusted ThingID records evidence-backed relationship claims; it does not turn a DPP creation event into legal ownership.
Policy / disclosureRelationship state, transferability, party identity, mandate, assurance, time-bounded acceptance and conflict rules.EvidenceTransfer intent, party authentication/mandate references, acceptance, previous/new claim linkage, timestamp and audit trail.API / event / connectorClaims / relationship API; mandate API; evidence API; lifecycle events for relationship claims.
Failure / retry / reconciliation
Recipient does not accept → expire transfer; conflicting claim → hold for policy resolution; replay/duplicate → idempotent rejection or return existing result.
