The JobQueue contract includes delay, idempotency keys, tags, retry metadata, and bounded shutdown hooks. These features make long-running work inspectable and help applications define duplicate delivery and retry behavior.
Why this matters
Jeston's design keeps the runtime explicit. The framework gives teams a place to express the contract, while the application remains responsible for provider choice, policy, failure handling, and operational measurement.
A practical reading rule
Separate supported behavior from experimental work, roadmap items, catalog metadata, and application responsibilities. That distinction is essential when adopting a framework and when writing upgrade documentation.

The inclusion of idempotency keys and retry metadata in the JobQueue contract is a smart design choice that enhances reliability in distributed systems. It allows developers to handle failures gracefully while maintaining the integrity of operations. I also appreciate your emphasis on keeping runtime explicit; this can significantly reduce debugging complexity in production. If you're looking for additional engineering support as you expand on these features, I'd be happy to discuss a paid collaboration. What challenges have you encountered while implementing these shutdown hooks?
