The Drift Signal manifests as a player file that appears slightly corrupted - not damaged, but offset in ways that suggest transmission interference. The tag shows different information depending on viewing angle, as if the data is being broadcast from a source in motion. It carries a faint, irregular vibration like a poorly-tuned radio, and official Bureau scanners cannot determine whether the signal drift is caused by external interference or deliberate manipulation by the holder.

Drift Signal marks players whose competitive signatures have been detected drifting between expected parameters, triggering enhanced surveillance and suspicion from the Bureau. Other players viewing a Drift Signal holder cannot determine if they're facing a genuine unpredictable force, a Bureau asset running controlled operations, or someone deliberately cultivating chaos for strategic advantage.
