ores.dq.core

ores.dq.core is the data-quality infrastructure library for ORE Studio. It provides the badge system (severity-tagged check results attached to datasets and artefacts), dataset and dataset-bundle management, change-management tracking, coding-scheme definitions, and the FSM / ORM base classes reused by all other domain components. Business logic is exposed as NATS message handlers; no other component in the system can own FSM transitions or ORM persistence without depending on ores.dq.

• NATS request messages from UI clients and peer services (badge queries, dataset/bundle CRUD, change-management events).
• PostgreSQL connections to ores_dq_* tables.
• Domain-specific events from trading, refdata, assets, and other components that trigger DQ population handlers.

• Badge and dataset records persisted to the ores_dq schema.
• NATS response messages for all DQ operations.
• ORM base classes, entity mappers, and FSM utilities consumed by ores.trading.core, ores.refdata.core, ores.assets.core, etc.
