// Execution readiness reported by a prepared SignalGraph snapshot.

// This contract is intentionally independent of SignalGraph's authoring and
// runtime declarations so hosts that only inspect routed-path readiness can
// include a small, stable surface. SignalGraph keeps its historical nested
// name as an alias to SignalGraphExecutionStatus.
