On 2026-08-21, our multi-venue tape recorded a ETH cascade: $76.1M in forced closes over 10 minutes (n=4,262 raw tape events in our own capture, not the whole market).
The liquidation map snapshot published 0 minutes before the start showed 13 levels; 4 were reached inside the cascade's traded range (n=13 levels, Wilson 95% lower bound 13%). Misses are shown at equal weight in the full autopsy.
The measured record at the time sat below its own validation gate - status only, per our honesty rules (the figure is not republished here).
