Core Bridge: RealDownloadService

All UI templates share this bridge class, mapping GeneralUpdate.Core events to the IDownloadService interface.

Bridge Logic (v10.4.6 stable)

// GeneralUpdate.Core Event → DownloadStatus State Machine Mapping:

GeneralUpdateBootstrap.AddListenerMultiDownloadStatistics
    → Downloading (update ProgressPercentage/Speed/Remaining)

GeneralUpdateBootstrap.AddListenerMultiDownloadCompleted
    → Processing files (extraction/verification)

GeneralUpdateBootstrap.AddListenerMultiAllDownloadCompleted
    → Applying → Success

GeneralUpdateBootstrap.AddListenerMultiDownloadError
    → DownloadError (after N automatic retries)

GeneralUpdateBootstrap.AddListenerException
    → Failed (non-fatal exceptions don't change state)
