PingContract

Contract for ping events during scheduled signal monitoring.

Emitted by pingSubject every minute when a scheduled signal is being monitored. Used for tracking scheduled signal lifecycle and custom monitoring logic.

Events are emitted only when scheduled signal is active (not cancelled, not activated). Allows users to implement custom cancellation logic via onPing callback.
