// DEE Action: ASA_Scenario4_ValidatePackerIo
// Scenario:   4 — Controller Version Update on Workflow Ready Signal
// Stage:      Post-Action Validation (second validation, after MaxStartupTime)
//
// Purpose:
//   After PackingController A/3 has been updated to A/4 and the instance has
//   confirmed started (MaxStartupTime passed), verify that the packer's I/O
//   connections are healthy. This catches cases where the runtime started but
//   field device communication has not been fully re-established.
//   If any I/O point is in a faulted or disconnected state, return false so
//   the task is marked ValidationFailed for operator investigation.
//
// Simulation:
//   The I/O health state for each resource is controlled by a per-resource
//   MES Configuration Entry, toggled independently from the MES UI:
//
//     Path : /Cmf/Tutorials/AutomationScheduleAction/Scenario4/IoHealthy/{resourceName}
//     Type : Boolean
//     Value: true  → all I/O points connected → ProcessedSuccess
//            false → I/O fault detected       → ValidationFailed
//
//   Example entries for the tutorial resources:
//     /Cmf/Tutorials/AutomationScheduleAction/Scenario4/IoHealthy/ASA Packer-01
//     /Cmf/Tutorials/AutomationScheduleAction/Scenario4/IoHealthy/ASA Packer-02
//
//   Set to false for a specific packer to demonstrate a ValidationFailed outcome
//   while other packers complete successfully.
//
// DEE Contract:
//   Input  - Task : AutomationScheduledActionTask  (includes linked resource via EntityName)
//   Output - Result : Boolean  (true = all I/O healthy, false = I/O fault detected)
//
// Fail-closed: any exception or missing config is treated as false.
