Mint pipeline.
The mint pipeline is deterministic. An encounter enters the pipeline only after both wallet signatures are present. The pipeline runs once per block (~12 seconds) and is publicly inspectable.
# Mint pseudocode — covenant Article III function mint_request(encounter) { require(patient_signed(encounter)); require(clinician_signed(encounter)); require(license_valid_at(clinician, encounter.signed_at)); instr = capture_instruments(encounter); require(len(instr) >= 1); axis = axis_math(encounter, instr, baseline=30); require(axis.lift >= threshold[axis.id]); return mint(patient_wallet, axis.lift); }
Axis thresholds.
Each of the eight axes has its own minimum-detectable-change threshold, set by the Council's audit committee on advice from the academic seats and reviewed annually.
| Axis | Code | Instrument family | Threshold | Mints / 1k events |
|---|---|---|---|---|
| Physiological Optimization | PO | HRV, BP, A1c, lipids | +0.4σ trailing | 312 |
| Nutritional Mastery | NM | FFQ, bloodwork, body comp | +0.5σ | 204 |
| Endurance & Recovery | ER | VO₂, FEV1, sleep | +0.6σ | 188 |
| Strength & Composition | SC | 1RM, DXA, grip | +0.5σ | 221 |
| Resilience & Stress | RS | PSS, cortisol, HRV-night | +0.4σ | 256 |
| Emotional & Social | ES | PHQ, GAD, social-PRO | +0.5σ | 198 |
| Therapeutic Adherence | TA | MPR, refill, biomarkers | +0.3σ | 344 |
| Preventive Vigilance | PV | USPSTF cadence, screens | +0.4σ | 209 |
Burn classes.
Of the 62,144 HCR ever burned, distribution by reason:
- Documentation reversal — clinician later corrected coding decision. 71% of all burns. The largest category by far.
- Billing claw-back — payer audited and reversed the underlying claim. 18%.
- Credential revocation — clinician was valid at signing, later suspended; events post-suspension are unwound. 8%.
- Fraud finding — Council audit committee found intentional misuse. 3%. Forty-two findings all-time.
Coverdell reserve.
The Coverdell Reserve is an opt-in custody pool, not a peg-keeper. Patients who don't want to manage their own keys can elect to have their HCR held by the Coverdell Health Trust at our institutional custodian. The reserve is capped at 15% of supply by Article V; today it sits at 6%. It is attested quarterly by an external SOC-1 firm; see attestations.
Network fees.
Mint and burn transactions cost gas, denominated in HCC. Patient-side mints are gas-subsidised by the network — patients never pay to receive HCR. Clinicians pay nominal gas (currently 0.0042 HCC per documentation event) which is reimbursed quarterly by the Council operating fund as long as documentation accuracy stays above 98%.
