The Tear Line manifests as a thin crimson thread woven through Bureau documents, connecting the torn edges where information was removed. The jagged tear pattern creates a distinctive visual signature - never clean, always irregular. The depth and density of tears correlate with the classification level of removed content: single thin tears indicate minor redactions while deep, ragged lacerations signal major secrets. Only players with Level 3 clearance or higher can perceive the full Tear Line pattern.

Tear Line serves as both threat and opportunity within the Containment Zone. When you discover a Tear Line on another player's file, you know the Bureau considers them significant enough to hide - but you cannot determine whether that's because they're a dangerous operative or a valuable asset. The uncertainty is the point. Players who master Tear Line interpretation gain unprecedented intelligence about competitors, but attract Bureau attention for 'observing beyond clearance.'
