/**
 * A run's TERMINAL VERDICT: the way an agent's run ended that its caller must
 * receive as a typed error, held as a plain value a chart's state can carry.
 *
 * An agent ends some runs on a record in its state instead of a throw — a
 * reliability fail-fast, a policy halt, a denied message, a refused answer —
 * and only its run boundary (`Agent · finalizeResult`) turns that record into
 * the error. A composition mounts the agent's CHART, so that boundary never
 * runs: the composition asks the agent what the mount handed back
 * (`outcomeOf`, duck-typed — `core-flow/` imports no runner): its answer, or
 * the verdict read off the state its chart ended with. It carries the verdict
 * and raises the SAME error (`terminalErrorOf`). One translation, used by the
 * agent's own boundary and by every composition.
 *
 * Leaf module: the error classes only, no runner.
