This holds classification tags associated with this fault/event instance, categorizing it (for example as environmental, configuration, or connectivity related). These tags let an admin or automated system filter and group active instances by category, which is how a dashboard might, for instance, surface only 'environmental' faults across the whole domain during a facility-cooling investigation. A tag of 'environmental' on this instance would route it into a facilities-focused view rather than a networking-focused one during triage.
