How it works

From public records to a defensible starting point.

SentinelGraph preserves the source, identity basis, relationship fields, and release context needed to investigate an interesting connection without overstating what it means.

  1. 01

    Version the sources

    Load current NPPES provider and HHS-OIG LEIE records into an immutable, dated release with hashes and provenance.

    • NPPES identity and provider fields
    • LEIE exclusion records
    • Source and retrieval dates
    • Reproducible release manifest
  2. 02

    Resolve identity carefully

    Keep exact NPI associations separate from name-and-state candidates. Ambiguous names are suppressed or labeled for verification.

    • Identifier validation
    • Name and state comparison
    • Ambiguity suppression
    • Match basis displayed to users
  3. 03

    Build source-literal relationships

    Create graph nodes and edges only from selected source fields. Generic role nodes and implausible routing-label addresses are excluded.

    • Provider roots
    • Addresses and telephone numbers
    • Authorized officials
    • Source-verification flags on edges
  4. 04

    Order human review

    Use deterministic signals to prioritize leads, then show the underlying graph, source context, uncertainty, and alternative explanations.

    • Priority scores, not probabilities
    • Deterministic triage and narrative
    • Bounded grounded Ask
    • Independent verification required

What the product can say

These source fields match. These records share this address or telephone number. This identity match is exact or candidate-level. This connection is prioritized for review.

What the product cannot say

This person committed fraud. This shared address proves control. This score predicts wrongdoing. This lead should trigger prosecution, referral, exclusion, or another adverse action.
