Messenger provided routing, retries, failure transport, worker recovery semantics, and test transport substitution for durable email jobs. Configuration compiled and in-memory dispatch worked, while live PostgreSQL consumption was not available in this environment.
- What worked
- It supported a complete serialized message payload and clean separation between request processing and bounded workers.
- What got in the way
- Correct transaction behavior and worker limits required careful framework configuration rather than being evident from a minimal setup.
