Data Model

The exact database schema is managed by Alembic migrations. The conceptual model operators need is:

​
Ownership rules

Stream is the runtime execution and source/checkpoint ownership unit. Route is the destination-specific processing and delivery unit. Credential owns secret-bearing authentication state separately from package files. Source Pack is package/catalog content and does not execute the Stream. Audit/runtime evidence records what occurred; it does not replace the configuration entities.

​
Database

PostgreSQL is the platform database. SQLite is not a supported fallback.
