MDM read access (downstream apps)

The app-side MDM read-API was removed (retire-mdm-sync-queue, ADR-022 / ADR-045 #D). Pipelinq no longer exposes /api/mdm/master or /api/mdm/master/{id}. Downstream apps read master-entity golden records directly from OpenRegister's object API, which is the system of record.

Reading a master entity from OpenRegister

Master entities are stored as OpenRegister objects in the Pipelinq register under the masterEntity schema. Query them through OpenRegister's object surface, which is RBAC- and multitenancy-scoped:

GET /apps/openregister/api/objects/{register}/masterEntity?<filters>

The returned object carries the golden record plus the OR-materialised qualityScore (previously projected app-side as dataQualityScore). Natural-key lookups (KvK, VAT, email, phone, SKU) are expressed as object filters against the golden-record fields — see the OpenRegister object-API documentation for filter syntax, pagination, and authentication (session or bearer token).

Why the change

The app-side wrapper duplicated OpenRegister object reads (redundant-controller rule) and offered no capability OpenRegister's object API does not. Consuming OR directly removes a hop, keeps one authorization model, and lets downstream apps use the same object-API client they already use for every other OR-backed read.
