Source registry
Each monitored source has a type, region, credibility tier, language, activity flag, and expected update cadence.
Verified Data Boundary
Official-source material is the preferred basis for public updates and case data. Non-official signals can support discovery, but they do not update verified case snapshots without human review.
Case reports
Dated, source-backed case reports are the durable record. Ambiguous parsed records stay in review.
Snapshots
Country snapshots are derived from the latest published report so map rendering stays fast and traceable.
