Operators

Every operator call is a Lisp form, (op args…), with no infix and no method chains. Effects (set, fetch, persist, emit, render-ui, …) run inside a transition; the rest compute values in guards, effects and render bindings. A (fn …) lambda is legal only in the slot an operator declares for it. This reference is generated from the same registry orb validate checks against, so a name that is not here does not exist.
