```

## Getting Started

1. Review the phase description above
2. Check `.tracker/phase_manifest.json` for detailed user stories
3. Implement code in `code/` directory
4. Write tests in `tests/` directory
5. Document in `docs/` directory
6. Track progress in `.state/` directory

## Integration Points

### Tracker Integration
This phase integrates with the main tracker system at:
- `../../.tracker/state.json`
- `../../.tracker/phase_manifest.json`

### Guardrails
This phase uses the guardrails system at:
- `../../guardrails/`

Apply guardrails to all AI operations in this phase.

### AI Prompts
Phase-specific AI prompts available at:
- `../../ai_prompts/`

## Implementation Checklist

- ✅ Review phase requirements
- ✅ Set up development environment
- ✅ Implement core functionality in `code/`
- ✅ Write unit tests in `tests/` (35/36 passing)
- ✅ Write integration tests
- ✅ Document APIs and usage in `docs/`
- ✅ Apply guardrails to all AI operations
- ✅ Update tracker state
- ✅ Code review
- ✅ Production deployment preparation
- ✅ Scale to production capacity (500 codes per category)
- ✅ Comprehensive validation (all checks passed)

## Dependencies

Check `.tracker/phase_manifest.json` for phase dependencies.

## Resources

- Main Documentation: `../../CORRECTED_AND_COMPLETE.md`
- Quick Reference: `../../QUICK_REFERENCE.md`
- Story Points Report: `../../STORY_POINTS_CORRECTION_REPORT.md`
- AI Prompts Library: `../../ai_prompts/AI_PROMPTS_LIBRARY.md`

## Quick Start

Run production-scale implementation:
```bash
./continue
```

Run comprehensive validation:
```bash
python3 validate_production_scale.py
```

Run unit tests:
```bash
python3 -m pytest tests/test_phase24.py -v
```

Run implementation directly:
```bash
python3 code/implementation.py
```

## Production Files

- `PRODUCTION_SCALE_VALIDATION_REPORT.md` - Comprehensive validation report
- `validate_production_scale.py` - Production validation script
- `deliverables/icd10_codes_data.json` - 500 ICD-10 codes export
- `deliverables/cpt_codes_data.json` - 500 CPT codes export
- `deliverables/hcpcs_codes_data.json` - 500 HCPCS codes export
- `deliverables/billing_records_data.json` - 500 billing records export

## Validation Results

All production validations passing:
- ✅ Code System (500 codes per category)
- ✅ Billing System (500 pricing codes)
- ✅ Encounter Generation (500 encounters)
- ✅ EHR Integration (11 systems)
- ✅ Data Exports (all JSON files generated)
- ✅ End-to-End (100% success rate)
