Know which door to knock on first.
LeadSentry turns an address into an explainable childhood lead-exposure risk assessment, helping public-health teams direct testing and outreach where limited resources can matter most.
The mission
Prevention is an allocation problem.
Health departments can test for lead exposure, distribute filters, and conduct outreach. The hard part is deciding which addresses to prioritize before harm is detected. LeadSentry combines environmental evidence, housing-age context, and explicit confidence rules into one traceable decision.
Not a diagnosis. LeadSentry is a transparent triage assistant. It ranks where preventive attention may be most valuable while preserving the sources, missing inputs, and location-quality caveats behind every result.

AWS architecture
One request. Five accountable steps.
The model does not invent the score. Deterministic tools own calculation; the agent owns interpretation. AWS supplies a repeatable, serverless path from request to persisted assessment.
Expose public HTTPS entry points backed by the same Lambda.
Validates input and runs the existing LeadSentry workflow.
Combines housing age, contamination, and water-service evidence.
Stores the full assessment, evidence, action, and timestamp.

Ground-truth check
A ranking should meet reality.
Across 26 Erie County ZIP codes, LeadSentry's land-weighted mean score was compared with public childhood blood-lead outcomes from the New York State Department of Health.
Correlation does not turn a triage score into a clinical diagnosis. It does provide encouraging evidence that the ranking captures a useful signal for deciding where deeper investigation may be warranted.

Built for accountable action
An agent should show its work.
LeadSentry preserves source provenance, exposes missing inputs, compares agent decisions with a rule baseline, and keeps its deterministic scorer testable. The result is not a black-box prediction; it is an auditable recommendation for where preventive attention may matter.
