Cold Case files possess three key properties: Permanence - once a player is flagged, the Cold Case designation never fully disappears from their record, even if they clear the initial investigation; Reactivation - dormant cases can suddenly become active based on player behavior, triggering when patterns match historical anomalies; and Visibility - the existence of a Cold Case is visible to all clearance levels, but the contents remain heavily redacted, creating paranoia about what the Bureau actually knows.

Cold Case serves as the Bureau's ultimate warning system - players who accumulate too many anomalies across leagues get flagged, and their records are moved to the Cold Case archive where they become targets for investigation by other competitors seeking clearance bonuses. This creates a persistent atmosphere of suspicion where even successful players must worry about their past catching up with them.
