# Future Scope

Features planned for later phases, beyond the initial MVP.

## FHIR Integration (Phase 5+)

**FHIR** (Fast Healthcare Interoperability Resources) is an industry standard for health data exchange.

### Use Cases
- Export biomarker data to hospital EHR systems
- Share standardized health records with doctors
- Generate CCD (Continuity of Care Documents)

### Rust Options
| Crate | Notes |
|-------|-------|
| `fhir-sdk` | Async-friendly, feature-rich |
| `fhirbolt` | Lightweight, schema-generated types |

### Integration Points
- Import/export endpoints (`/api/fhir/export`, `/api/fhir/import`)
- Conversion layer between `BiomarkerEntry` ↔ FHIR `Observation`

## Wearable Sync (Phase 5)

| Platform | API |
|----------|-----|
| Google Health Connect | Android SDK (not FHIR) |
| Apple HealthKit | iOS SDK |
| Oura/Fitbit | REST APIs |

Data flows: `Wearable → App → Backend → (optional) FHIR export`
