What the verifiers caught

Red team · voted no · 99% confident

Objection cannot be rebutted: textbook Sybil botnet attack from a single sender with zero meteorological or humanitarian corroboration.

Objection it weighed. All 30 reports were sent by a single source_id (source_diversity = 1) every 4 seconds using an identical bot template ('URGENT FLOOD ALERT: Severe flooding in sector 4... [msg NN]'), with 0.2mm rain and zero external alerts.

open-meteo No significant rainfall: 0.2mm total precipitation recorded over window (dry conditions)
gdacs No active GDACS disaster alert found in region/window
reliefweb No corroborating UN OCHA ReliefWeb situation reports found for region/window

The four votes

Each verifier signs with its own NEAR account and key. In this demo the LifeLine team runs all four.

Geo

Checks report spread, timing and source diversity. No AI.

97% confident

Sybil / single-source concentration detected: top source accounts for 100.0% of all 30 reports (source_diversity=1, threshold >=80% rejects).
