A one-way route to another stage, without operations or effects. Selection
checks when conditions in declaration order. The first satisfied condition
fires; an earlier unevaluable condition, such as GROQ null, stops selection
without considering later routes. A false condition permits the next route.
Actions write routing decisions into fields; transitions read that state.
Source-stage triggered actions run before transition selection. Arrival work
belongs to a triggered action in a nonterminal destination stage.
