Interface Railway

A railway over flat subagents. steps run in order on the success track; the first step that returns an error short-circuits to onError. recover optionally retries the failing step a bounded number of times before the error track. There is intentionally no loop combinator — the value is a finite tree, so it always terminates and is fully verifiable at compile time.

    _specType: "railway";
    name: string;
    onError?: RailwayStep;
    recover?: { max: number; step: RailwayStep };

onError?: RailwayStep

Error track — runs with the failing step's error payload.

`Optional` `Readonly`recover

recover?: { max: number; step: RailwayStep }

Bounded recovery: retry the failing step up to max times (finite).
