On 2026-10-22, our multi-venue tape recorded a BTC cascade: $75.4M in forced closes over 10 minutes (n=6,659 raw tape events in our own capture, not the whole market).
The liquidation map snapshot published 4 minutes before the start showed 29 levels; 9 were reached inside the cascade's traded range (n=29 levels, Wilson 95% lower bound 17%). 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).
