Each bubble = one cercle. Size ∝ √population, color = region. Hollow rings mark cercles with limited or missing school-data coverage. Upper-right = both signals firing; right edge alone = conflict-only watch list.
Critical Tier = top 5 cercles with reliable school-data coverage. 22 of 50 cercles are flagged Data-Limited — coverage too thin to trust the closure signal; triage falls to field-team verification.
EDI weights: 50% closure rate · 25% ACLED events / 100k · 25% fatalities / 100k (2020–2024). Each input normalised to dataset max.
