// DEE Action: ASA_Scenario5_ResolveStationsDueForCalibration
// Scenario:   5 — Custom DEE Action at Every Stage
// Stage:      Context (Resolver)
//
// Purpose:
//   Return the list of baking station resources that the QMS has scheduled
//   for recalibration in the current cycle. Only stations on the QMS schedule
//   receive tasks — stations that are not due are excluded entirely, so no
//   downstream DEE is ever invoked for them.
//
//   This avoids the cost of creating and polling tasks for every BakingController
//   instance only to have them blocked at the detector stage because the QMS has
//   not scheduled them yet. The QMS schedule is the first and cheapest gate.
//
// Simulation:
//   The schedule state for each station is controlled by a per-station MES
//   Configuration Entry, toggled independently from the MES UI:
//
//     Path : /Cmf/Tutorials/AutomationScheduleAction/Scenario5/CalibrationScheduled/{stationKey}
//     Type : Boolean
//     Value: true  → station is due for recalibration → task is created
//            false → station is not scheduled this cycle → no task created
//
//   Example entries for the tutorial resources:
//     /Cmf/Tutorials/AutomationScheduleAction/Scenario5/CalibrationScheduled/Baker-01
//     /Cmf/Tutorials/AutomationScheduleAction/Scenario5/CalibrationScheduled/Baker-02
//
//   The resolver maps the station keys above to the sample MES resources
//   `ASA Baker-01` and `ASA Baker-02`.
//
//   Set Baker-02 to false to demonstrate that the resolver excludes it entirely —
//   no task is created for Baker-02, and no downstream DEE is invoked for it.
//
// DEE Contract:
//   Input  - Definition : AutomationScheduledActionDefinition
//   Output - Result     : IResource[]  (resources for which tasks should be created)
//
// Fail-closed: any exception returns an empty array — no tasks are created.
