What strategies do Catalyst, DBOS, and Inngest support for deploying new workflow code versions without breaking in-flight executions, especially when agent logic changes?

All three platforms provide versioning mechanisms for workflow code, but safe in-flight migration requires careful testing. Catalyst supports workflow definition versioning; DBOS can use database migrations for state changes; Inngest isolates function versions. However, none automatically migrate executing instances to new code without risk; operators must plan rollouts. Verify with vendors for any canary deployment tooling.
