TheOmenDen.StreamPulse.Scripting.Attributes.OnScheduleAttributeMarks a method as a handler fired on a cron schedule. The method must accept
(IScriptContext, ScheduleContext); the context carries the fire instant. A compiled graph carries
its authored cron expression as graph metadata — the host registers a durable scheduled job that fires
the handler at each occurrence. Missed occurrences (host offline) are skipped, not caught up.
