What to build

The database catalog (chapter 16) is applied from the estate-scoped artifact against the Postgres the handover ledger's serving entry names, while the data Project is still on the old path, as the Vault policy job already does for Vault. It creates <project>_db with its owner role <project>-owner and data role <project>-data, adopts an existing <project>_db by reassigning its objects once to <project>-owner, and the policy job writes the matching Vault database roles.

Acceptance criteria

• The spec states where the catalog applies while data is legacy, and how an existing database is adopted.
• Both implementations and their oracles, with a worked example.
• Applied twice, the catalog changes nothing the second time.
• npm run verify and the emf build pass.

Blocked by

• None (can start immediately)
