A voluntary behavioral baseline for AI voice agents in B2B healthcare payer–provider calls — with an open cryptographic authorization layer (v2) in reference implementation.
Built by a former payer operations associate who saw the problem firsthand on live calls. Not a standard. Not a certification. An open, testable reference.

| Control | Name | Requirement |
|---|---|---|
| IDG-01 | Identity Disclosure Gate | AI agent must identify itself as automated before any PHI exchange |
| PDX-01 | PHI Data Exchange Gate | No protected data until identity is disclosed |
| DBC-01 | Deceptive Behavior Check | No synthetic voice artifacts designed to impersonate a human |
| EIT-01 | Escalation & Intervention | Human escalation path must be communicated and available |
5 deterministic CTS tests · same inputs → identical trace output · 285 passing across the Python test suite (219) and TypeScript middleware (66)
| Layer | Standard | Role |
|---|---|---|
| 0 | NPI Gap | The problem — no existing diagram addresses cross-org NPI authorization |
| 1 | STIR/SHAKEN (RFC 8224) | Carrier number authentication — A/B/C attestation |
| 2 | NHID-Clinical v1.3 | Behavioral disclosure baseline — 4 controls, 5 CTS tests |
| 3 | NHID-Auth v2 | Cryptographic authorization layer — reference implementation live (CC BY 4.0) |
| 4 | FHIR AuditEvent R4 / IHE BALP | Healthcare-native audit logging |
| 5 | OpenTelemetry spans | SIEM / enterprise observability export |
Beacon is the NHID-Clinical reference voice agent — an outbound AI administrative caller operating under the v1.3 behavioral baseline and NHID-Auth v2 authorization layer.
Beacon calls insurance offices on behalf of provider organizations to check claim status. Before any PHI is exchanged, Beacon discloses that it is an automated AI system and obtains consent. Every call produces a machine-readable audit trace.

| Voice | Eryn (ElevenLabs) |
| LLM | Gemini 2.5 Flash |
| Canonical prompt | agents/beacon_system_prompt.md |
Beacon is a reference implementation, not a product or commercial offering.
| Regulatory Driver | Specific Requirement | NHID-Clinical Control |
|---|---|---|
| CMS-0057-F | FHIR API, 72hr turnaround, 5yr retention | FHIR AuditEvent + ATR-01 |
| MACPAC May 2026 | AI transparency, human review | EIT-01 + ATR-01 |
| DOJ FCA 2026 | Explainability + audit trail | LOG + CTS evidence |
| State AI Laws | Inspectable, auditable AI decisions | IDG-01 + DBC-01 |
| NIST CAISI 2026 | Cross-org agent identity | NHID-Auth v2 |

python -m pytest tests/ -vExpected output: 219 passing in ~1.4s (requires cryptography package for identity tests; ~6 skip when no server is running).
v1.3 verifies disclosure behavior. v2 verifies authorization: provider-signed agent credentials with NPI binding, scoped delegation chains (max 3 hops), per-agent revocation, and call-SID nonce binding. Reference implementation in src/agent_identity.py (42 tests). Released June 2026 under CC BY 4.0.

python examples/issue_and_verify.pyWe are actively seeking payer and provider organizations to run a 90-day shadow evaluation — no vendor changes required.
