Ground Truth
Environmental public-record reporting for a US address. Independent sources load in parallel; report values link to agency records and raw fields. Failed sources remain visible rather than blocking the whole report.
- TypeScript
- Next.js
- Cloud Run
The problem
Environmental records sit across independent federal systems. Readers need to see which records support an address report and know when a source failed.
Implementation decisions
- Query independent sources in parallel so one failure does not block the report.
- Carry field-level provenance, retrieval URLs and response hashes alongside reported values.
- Use source-backed templates and show source failures instead of inventing a combined home-safety score.
