What this page states · not a verdict

Drawn in 26 strokes over 00:00:29, across 2 sittings. Whether external images were imported is not checked in this record (v0). The record alone allows it to be replayed from the beginning.

Forgery difficultyHigh56/100top 64% hardest to fake

To forge this process exactly, one would have to reproduce the pressure, timing, and tremor of all 26 strokes — one by one. This isn't a verdict; it reflects how dense the recorded signals are.
