I’d like to take this because I’ve worked on backend reliability patterns where retries and partial failures need to be handled safely.

I can extend the idempotency helpers to support multi-step flows, ensuring operations can be safely retried or resumed without duplicating side effects. I’ll also design it so clients can recover cleanly from failures across planning and execution stages, with clear guarantees for integration safety in future workflows like vault operations.
