Crosshatch

The Crosshatch system was implemented after the 'Holladay Signal' incident revealed that players were manipulating clearance levels to spy on each other. The Bureau created Crosshatch as a response - a system that shows different information to different clearance levels in intersecting patterns, making it impossible to map what anyone else can see. What began as a counter-surveillance measure became the primary tool for maintaining perpetual uncertainty in the Containment Zone.

The Crosshatch tag manifests as a translucent identification card with intersecting diagonal lines creating a visible crosshatch pattern. The pattern shifts based on viewing angle - what you see changes as you move around it. Embedded micro-text is visible only at certain angles, revealing fragments of information the holder may not even know exists. The tag partially obscures the holder's actual score history from lower clearance viewers while showing different fragments to different observers, ensuring no two players ever see the same complete picture.

Crosshatch determines what competitive intelligence players can access about opponents based on their security clearance level, creating persistent uncertainty about what information is actually visible. It serves as the Bureau's primary mechanism for maintaining the 'Trust No One' atmosphere - every player knows their record is being partially observed, but no player can ever determine the full extent of that observation or what others can see about them.
