// =============================================================================
// DEE Action: ASA_Scenario5_CheckMaintenanceWindowOpen
// Scenario:   5 — Custom DEE Action at Every Stage
// Stage:      PreCondition (second precondition, after AllowedWeekdays)
//
// Purpose:
//   Check whether the global QMS maintenance window is currently active.
//   This is a global gate: if it returns false, ALL tasks are skipped on this
//   polling pass — no individual oven checks are performed.
//   This DEE is intentionally placed after the native AllowedWeekdays check
//   so it is never invoked on weekends, keeping QMS call volume low.
//
// Simulation:
//   The global maintenance window state is controlled by a single MES
//   Configuration Entry toggled from the MES UI:
//
//     Path : /Cmf/Tutorials/AutomationScheduleAction/Scenario5/MaintenanceWindowOpen
//     Type : Boolean
//     Value: true  → window is open  → all tasks proceed to detector evaluation
//            false → window is closed → all tasks skipped with SkippedPreConditionFailed
//
//   Set to false to demonstrate how a closed window blocks all tasks simultaneously,
//   regardless of individual oven readiness.
//
// DEE Contract:
//   Input  - Task : AutomationScheduledActionTask  (minimal context — precondition stage
//                   has no target entity; this check is global)
//   Output - Result : Boolean  (true = window open, false = window closed)
//
// Fail-closed: any exception or missing config is treated as false.
