When it was drawn

What this page states · not a verdict

Drawn in 17k strokes over 07:23:19, across 14 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 difficultyVery high87/100top 34% hardest to fake

To forge this process exactly, one would have to reproduce the pressure, timing, and tremor of all 17k strokes — one by one. This isn't a verdict; it reflects how dense the recorded signals are.
