Feature notes: DecayedConfidenceCalculator and ObservationDecay are fully implemented. TriageQueueEvaluator and UnknownTriageQueueService provide automated triage. What's Missing items (triage queue UI, real containment data sources, decay notification, historical decay ledger) are future enhancements not blocking core decay+triage functionality.",
