Expand description
Deterministic workflow orchestration engine.
Scripts never call LLMs. They issue WorkflowHostRequest values over a
channel; a product host executes nested agents and replies. Results are
recorded in a Journal for resume.
Dependency firewall: this crate must not depend on machi-llm or
HTTP provider stacks.
Maturity: core.
