When it was drawn

What this page states · not a verdict

Drawn in 41 strokes over 00:00:22, in one sitting. Whether external images were imported is not checked in this record (v0). The record alone allows it to be replayed from the beginning.

Forgery difficultyHigh58/100top 58% hardest to fake

To forge this process exactly, one would have to reproduce the pressure, timing, and tremor of all 41 strokes — one by one. This isn't a verdict; it reflects how dense the recorded signals are.
