The Contagion

A Crisis Narrative — 7 beats, 4 domains, hundreds of contacts

Beat 1: Patient Zero Identified

Carlos Mendoza (CID COR-AL01-271845) presents at a Porto Sereno clinic with acute respiratory symptoms. His complete government profile reveals touchpoints across all 10 domains — employment, education, property, tax, civil registry, and more. A single query reconstructs his entire civic footprint.

Beat 2: Economic Network Exposure

Carlos works for a business registered as BIZ-001102. Tracing its economic network reveals employees, tax filings, and port shipments connected to the same entity. Every person in this network is a potential exposure.

Beat 3: Social Services Cross-Reference

Public health officials need to identify everyone in Porto Sereno who has recent healthcare records. Cross-referencing Civil Registry addresses with Healthcare facility visits finds people who may have been exposed at the same clinics Carlos visited.

Beat 4: Supply Chain Trace

The MV Estrella del Sur arrived at Porto Sereno days before Carlos's symptoms appeared. Tracing the vessel's cargo and operator through the Business Registry reveals who handled the shipment and whether the contagion came ashore with the cargo.

Beat 5: Family & Household Exposure

Carlos's household must be quarantined. Pulling all records sharing his National ID across domains shows family members, dependents, and anyone co-registered at the same address — the immediate exposure ring.

Beat 6: Institutional Impact Assessment

The university where Carlos studied (BIZ-000847) has thousands of students and faculty. Pulling Business Registry details and Education records shows the institutional footprint — anyone connected to the university who may need testing.

Beat 7: Full Contagion Contact Trace

The complete 4-tier contact trace. Tier 1: Patient Zero's healthcare record. Tier 2: Maritime vessels and crew at Porto Sereno. Tier 3: Law enforcement quarantine response records. Tier 4: Education contacts at the affected campus. One query, four domains, hundreds of contacts — executed in seconds because SDC4 components share deterministic identifiers across every domain.
