The Hotspot Testimony manifests as brilliant white spots burned into magnetic tape substrate, growing brighter with each playback cycle. These thermal signatures create visible temperature gradients - hot zones where consistent attendance has worn the oxide layer thin enough to glow, cold zones where absence left the tape pristine and dark. Under proper wavelength examination, the pattern reveals a complete attendance history written in progressive degradation, with the brightest hotspots marking players who've made contact every week across multiple simulations.

Functions as the paradoxical proof system that converts mechanical damage into credible evidence, making tape degradation the highest form of attendance verification - proving that in the Chaintrix, pristine recordings indicate absence while damaged tape glowing with hotspots proves presence across all 16 movie-themed leagues.
