The supervision a workflow declares: the decision settings (a default +//! decision model and monitors) and the phase plan its chat starts with. +//! +//! A workflow file carries them in two optional top-level blocks, each named +//! after the `extension_data` record it seeds: +//! +//! - `decision_settings` is [`DecisionSettings`] verbatim, the record the +//!
