What it detects

Blink / FakeLag / ScaffoldBlink / LagRange detector — the cheat cancels and queues outgoing packets, so the entity appears frozen then snaps a large distance.

Observer signature

mag = sqrt(dx^2+dy^2+dz^2); mag < 0.01 increments freeze; on a move, if freeze >= 5 && mag > threshold (2.0), flag 'Blink'; resets freeze. Flags the pure freeze-snap shape so non-combat blinks are caught too.

False-positive guards

  • Vehicle/gliding/riptide exempt
  • Teleport exempt (tick - lastTeleportTick < 10, resets freeze)
  • Hurt exempt (tick - hurtTick < 3, resets)
  • Server-lag exempt (LAG_WINDOW=8 / BURST_WINDOW=3, resets freeze and skips)
