# Depureco USA AI Website Database Package v4

Last updated: 2026-06-10

v4 is a gap-fill and relationship-mapping pass over v3. It adds external authority context, entity graphing, URL/canonical inventory, selector rules, priority fusion, product claim validation, intent guardrails and source/schema audits.

## Counts
- URL inventory records: 6541
- URL watchlist records: 1895
- Entity graph nodes: 834
- Entity graph edges: 1027
- Selector rules/questions: 40
- Product claim validation records: 349
- Manual/deprioritized source sheets: 71

## New public files
- /ai/db/external-authority-reference-map.json
- /ai/db/entity-relationship-graph.json
- /ai/db/live-url-canonical-inventory.json
- /ai/db/solution-selector-rules.json
- /ai/db/priority-fusion-map.json
- /ai/db/ai-schema-gap-map.json
- /ai/db/source-sheet-audit-v4.json
- /ai/db/intent-guardrail-map.json
- /ai/db/product-claim-validation-map-v4.json
- /ai/ai-topic-router-v4.md

## Remaining work
The biggest remaining gap is a live crawl/canonical/noindex/header check and a spec-sheet/PDF extraction pass before making very specific product-level capability or certification claims.
