Appears as ghostly white tide lines on fabric and darkened patches on leather that tell the story of each day's labor - the reins show grip patterns, the hatband reveals hours under sun, the shirt collar maps the neck's testimony of heat and strain, all written in salt that won't wash away and stains that deepen with each passing season. These marks accumulate into permanent archives that transform soft gear into stiffened, salt-crusted testament. The patterns vary by task and faction, creating unique signatures readable only by those who know the work intimately enough to distinguish genuine labor from fraudulent claims.

Acts as the permanent record keeper that transforms bodily fluid into irrefutable documentation of who worked hard enough to survive elimination. When competitive scores fail to clearly separate worthy from unworthy, faction elders examine gear under harsh sunlight, reading salt patterns like scripture to render final judgment on who genuinely earned their position through sustained labor versus who rode on temporary advantage.
