When it was drawn

What this page states · not a verdict

Drawn in 12 strokes over 00:00:05, 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 difficultyModerate48/100top 77% hardest to fake

To forge this process exactly, one would have to reproduce the pressure, timing, and tremor of all 12 strokes — one by one. This isn't a verdict; it reflects how dense the recorded signals are.
