Why 100 Days
Big visions die in vague timelines. A 100‑day sprint forces focus: prove low‑cost clearing on two high‑variance domains (insulins, outpatient imaging), demonstrate open arbitration, and show that gratitude‑forward UX can coexist with rigor.
Day‑100 deliverable: a public, queryable receipt showing every transaction cleared, every anomaly caught, and the administrative cost—down to the cent.
Founding Circle (The “Who”)
- Chief Ethicist (AI alignment): owns model audits, bias checks, model cards, red‑team drills.
- Chief Actuary / Systems Engineer: corridor math, SRV layers, solvency targets, simulation harness.
- Chief Public Advocate: community standards, transparency policy, member messaging, FOIA‑grade docs.
- Chief Data Architect (FHIR + Ledger): Node schema, FHIR/X12/NCPDP mapping, conformance, security.
Supplement with 2–3 engineers (API & data), 1 compliance/SOC‑2 lead, and an arbitration coordinator.
Anchor Partnerships (The “Allies”)
- Academic health‑economics lab: corridor research, bias audits, independent evaluation.
- State employee plan or large self‑funded employer: pilot venue for insulin + imaging.
- EHR / claims vendors: mapping support to FHIR/X12/NCPDP; test data plumbing.
- Imaging center chains + independent pharmacies: high‑variance price domains with willing partners.
Prototype Exchange (The “Proof”)
Stand up a minimal but real clearing rail for insulins (retail/specialty) and outpatient imaging (MRI/CT).
Why these two?
- High price variance: ample room to capture and document surplus.
- Clear data structures: NDC/RxCUI for insulins; CPT/HCPCS for imaging; straightforward J‑codes.
- Simple, explainable cost stacks: easy to show public “how the sausage is made.”
Cost stack we will publish (insulin example)
WAC or acquisitionbasis (contract/NADAC/340B, with provenance)Distributor markup(where applicable)Pharmacy dispense fee/marginAdmin fee(if medical route)- Final allowed price within corridor (e.g., reference ±15%)
For imaging, add site‑of‑care factor and equipment utilization where relevant.
Day 100: The Public Receipt (The “Symbol”)
An interactive, public page showing:
- Every transaction cleared with a signed trace (hash) and de‑identified fields.
- Variance vs. corridor; anomalies and their resolution path.
- Exact infrastructure cost (e.g., 0.0009 × allowed = $X) and captured surplus buckets.
- Thank‑You Economics: anonymized notes triggered by cost‑saving choices.

| Workstream | Owner | Artifacts (Day‑100) |
|---|---|---|
| UCL APIs | Data Architect | POST /claims/clear, POST /disputes, GET /nodes/{id}/corridor, signed traces |
| Corridor Math | Actuary | Reference cost sources, float rules, exception logic, bias checks |
| SRV (pilot) | Actuary | Trigger at ≥$50k; solvency target; contribution sketch; quarterly rebalance plan |
| Arbitration | Coordinator | Public docket, SLA timers, published decisions |
| Ethics | Chief Ethicist | Model cards, drift monitor, red‑team report |
| Security/Compliance | Compliance Lead | HIPAA risk assessment, SOC‑2 plan, DPIA |
Risks & Mitigations
- Data access lags: mitigate with de‑identified sandbox + synthetic data; parallel legal tracks.
- Stakeholder pushback: publish fee schedule, conflict policy, and corridor math in plain English; invite observers (shadow seats).
- Scope creep: two domains only; change‑control board; backlog the rest.
- Model bias: pre‑launch ethics audit; publish residuals by demographic proxies; add exception pathways.
Practitioner Appendix: Technical Chops
A) Prototype Exchange: Insulins
- Identifiers: RxCUI ↔ NDC set ↔ (if medical) HCPCS J‑code; device form (pen/vial).
- Cost stack: acquisition (WAC/NADAC/contract) + distribution + dispense fee/margin + admin fee (if medical) + site‑of‑care factor → corridor‑checked allowed.
- Member fairness: coinsurance applied to net; late rebates credit members.
B) Prototype Exchange: Outpatient Imaging
- Identifiers: CPT; modality (MRI/CT); body part; contrast Y/N; site type.
- Cost stack: technical + professional + facility; equipment utilization; site‑of‑care factor; corridor check.
- Arbitration: outlier hospital price routes to docket; decision updates corridor next quarter.
C) Public Receipt – required fields
- Node ID (de‑identified), date, site, allowed vs corridor, member share basis (net), signed hash, anomaly flags + resolution.
- Infrastructure fee disclosed as basis points and dollars.
D) Security/Privacy
- Minimum necessary fields; encryption at rest/in transit; audit logs; key rotation.
- De‑identification for public artifacts; BAAs for partner data; DPIA published.
