[Pi Pocket's subagent implementation](https://github.com/TannerMidd/pi-pocket/blob/3e6046612db4358b599da302d5c96bd407d9de5c/src/server/extensions/subagents.ts) gives each worker a retained conversation and uses durable tasks to deliver messages and report answers. Request IDs and recorded answer IDs prevent duplicate delivery and reporting after restart. The idea worth stealing: make the handoff durable, not just the worker.
