Corroborix: VerityPact
Powered by the Guardian Handshake
Two independent confirmations. One trusted record.
VerityPact is a healthcare service-verification and program-integrity platform. It asks a medical provider and a patient, veteran, caregiver or authorized representative - separately, and without either seeing the other’s response - whether a specific medical service actually occurred. The two answers are then compared by a deterministic rule set.
Agreement verifies consistency. Disagreement creates a question, not an accusation.
The Guardian Handshake
The protocol that protects the independence of the two responses.
- Each party responds independently and neither response influences the other.
- Neither party sees the other answer before submission.
- Each answer is stored as an attributable, immutable attestation.
- Matching is deterministic and safe to repeat.
- A mismatch opens a case for human review, never a fraud finding.
- Automated agents organize information; people decide outcomes.
How a verification works
One service. Two perspectives. One deterministic outcome recorded in Neon PostgreSQL with a complete audit history.
1. The provider confirms independently
The provider organization is asked, in its own words, whether it delivered a specific service to a pseudonymous beneficiary on a specific date.
2. The beneficiary confirms independently
The patient, veteran, caregiver or authorized representative is asked the same question from their perspective. Neither party sees the other answer before both are submitted.
3. VerityPact verifies or opens a question
Matching is deterministic. Agreement records a verified consistency result. Disagreement opens a structured discrepancy case for human review.
Every outcome is defined in advance
The verification matrix is a pure function of the two answers and whether a claim was billed. There is no model, no score and no judgement of intent.
| Provider | Beneficiary | Result | Case opened |
|---|---|---|---|
| Yes | Yes | verified_match | No |
| Yes | No | provider_confirmed_patient_denied | Yes |
| No | Yes | patient_confirmed_provider_denied | Yes |
| No | No (claim billed) | both_denied_billed_service | Yes |
| No | No (no claim) | service_not_delivered | No |
| One response | - | awaiting_second_attestation | No |
| No response | No response | expired_unverified | No |
| One response | Expired | partial_response_expired | No |
Built for everyone in the record
For program-integrity teams
- Deterministic, rule-based matching with no black-box scoring
- Every action attributable and recorded in an append-only audit trail
- Structured cases with neutral checklists instead of ad-hoc email threads
- Immutable attestations, versioned corrections and full state history
For patients, veterans and caregivers
- One plain-language question about one service, answered Yes or No
- An explicit “I need help identifying this service” option that is never treated as an answer
- No accusation: a mismatch is a question about a record, not about a person
- Pseudonymous references rather than names in the verification record
For providers
- A short, perspective-specific question tied to a single claim reference
- A clear record of what was asked and exactly what was answered
- A structured place to supply appointment, delivery or corrected-claim evidence
- Ordinary explanations such as coding or date errors are considered first
What this prototype is, and what it is not
This repository is a phase-one prototype running on synthetic demonstration data. It does not connect to any electronic health record, claims system, provider directory, identity-verification service, telephone system, messaging service or government system, and it must never be used with real patient information.
Corroborix is a veteran-founded company. Corroborix and VerityPact are not affiliated with, endorsed by, approved by, certified by or contracted by any government agency, insurance company or healthcare network. The platform is not HIPAA compliant, not certified and not production ready.
VerityPact does not promise to prevent fraud and never accuses a patient, provider, employee, organization, healthcare professional or representative of wrongdoing. It records what two independent parties said, and when those statements do not align, it asks a question.
