These packages connect work happening inside a capability to persistence, queues, projections, analytics destinations, and request-level enforcement without making those outside systems part of the domain contract.

## Composition rule

Domain packages publish events through explicit Bridge seams. Applications decide whether an event stays in-process, enters an outbox, becomes a queued job, updates a projection, or fans out to analytics.
