Each day, ICHI selects the single most consequential cyber event affecting internet-wide trust — supply-chain compromise, mass-exploitation wave, ransomware spike, or Tier-1 infrastructure outage — and records the dominant explanatory event and the VECTORS dimensions it affected. The Top Event is explanatory only; the headline composite score is the weighted VECTORS sum plus the two approved meta-condition uplifts (VID and Remediation Pressure), with no separate event uplift. This page is the running ledger.
