PLATFORM MODULEUI/UX BASELINE

Ownership, Custody & Delegation

Keep legal ownership, possession, custody, maintenance and delegation as separate evidence-backed relationships rather than DPP side effects.

SCOPE

What the module does—and what it deliberately does not do.

A clear negative boundary is part of the product definition.

DOES

Transfer, delegation, expiry, dispute, evidence linkage and independent status semantics.
Publishes explicit domain objects and version-aware interfaces/events.
Links business outcomes to evidence and architecture references.

DOES NOT

Does not replace external legal/identifier authorities.
Does not imply universal certification or conformity.
Does not make optional assurance mechanisms mandatory for all products.

OPERATING MODEL

Actors, inputs, outputs and authority remain explicit.

The module is not treated as a black box; its authority and evidence responsibilities are visible.

Actors

Owner · Possessor / Custodian · Delegate · Authority / dispute process

Inputs

Identity/context, versioned business data, policy inputs and external-source references as applicable.

Outputs

Versioned decision/data/evidence artifacts with correlation and provenance.

Authority boundary

Qualified by data domain; external authority is not absorbed through integration.

BUSINESS OBJECTS

Semantic objects connect UI, API, repository and evidence.

The semantic registry prevents architecture vocabulary from drifting between portals and integration contracts.

POLICY & EVIDENCE

Material actions are policy-versioned and evidence-linked.

Where the module changes a material state, the transition grammar applies.

Event

Authorized actor

Precondition

Evidence

Trusted time

Policy / profile version

Resulting state

INTERFACES & EVENTS

Reference contracts are versioned and publication-gated.

The public API package is a reference contract; actual deployment availability must be confirmed by release/environment.

POST /v1/claims/ownership
POST /v1/claims/custody
POST /v1/mandates

RELEASE GATE

SELECTINTEGRATETESTAPPROVEOPERATE

Publish support only for the exact version/profile/environment that has supporting evidence.

STANDARDS & LIMITATIONS

Mapping is not certification.

Standards are shown with status and implementation wording so reference mapping is not mistaken for assessed conformity.
