Lyra+ Ops Implementation Summary

Overview

This implementation adds automated data refresh capabilities and health monitoring to the ZLECAf project through:

1. GitHub Actions Workflow - Automated weekly data generation
2. Data Pipeline Script - Python script to generate AfCFTA datasets
3. Health Check API - Endpoint to monitor data file availability
4. Comprehensive Documentation - Setup and maintenance guides

What Was Implemented

1. GitHub Actions Workflow (.github/workflows/lyra_plus_ops.yml)

• Schedule: Runs every Monday at 06:15 UTC
• Trigger: Can also be manually triggered via GitHub Actions UI
• Permissions: Has write access to commit and push data changes
• Steps:
  1. Checkout repository
  2. Setup Python 3.11
  3. Install dependencies (openpyxl optional)
  4. Generate datasets using backend/make_release.py --demo
  5. Commit and push changes to frontend/public/data/

2. Data Generation Script (backend/make_release.py)

Features:

• Command-line interface with --demo flag
• Generates 5 key datasets:
  • zlecaf_tariff_lines_by_country.json - Tariff lines by country
  • zlecaf_africa_vs_world_tariffs.xlsx - Tariff comparison (CSV in demo mode)
  • zlecaf_rules_of_origin.json - Rules of origin by sector
  • zlecaf_dismantling_schedule.csv - Phase-out schedule
  • zlecaf_tariff_origin_phase.json - Integrated data

Demo Mode: Currently generates realistic sample data for testing. In production, this should be replaced with real integrations:

• e-Tariff Portal (official tariff schedules)
• UNCTAD TRAINS (trade data)
• OEC Observatory (economic complexity)

3. Health Check API Endpoint (/api/health)

Added to backend/server.py:

Endpoint: GET /api/health

Response Format:

{
  "ok": true|false,
  "files": {
    "zlecaf_tariff_lines_by_country.json": true,
    "zlecaf_africa_vs_world_tariffs.xlsx": true,
    "zlecaf_rules_of_origin.json": true,
    "zlecaf_dismantling_schedule.csv": true,
    "zlecaf_tariff_origin_phase.json": true
  },
  "message": "All data files present" | "Some data files are missing",
  "timestamp": "2024-01-15T10:00:00"
}

Use Cases:

• Integration with Netlify/Vercel deployment monitoring
• UptimeRobot or similar services for uptime monitoring
• CI/CD pipeline validation
• Health dashboards

4. Documentation

• docs/LYRA_OPS.md - Comprehensive guide covering:
  • Scheduling configuration
  • GitHub permissions
  • Production mode setup
  • API health endpoint usage
  • Testing procedures
  • Maintenance guidelines
• frontend/public/data/README.md - Data directory documentation

5. Tests

• tests/test_health_endpoint.py - Unit test for health check logic
• tests/test_lyra_ops_integration.py - Full integration test suite

How to Use

Manual Data Generation

# Demo mode (uses sample data)
python backend/make_release.py --demo

# Production mode (not yet implemented)
python backend/make_release.py

Test Health Endpoint

# Start backend server
cd backend
uvicorn server:app --reload --port 8000

# Test health endpoint
curl http://localhost:8000/api/health

Trigger Workflow Manually

1. Go to repository’s Actions tab on GitHub
2. Select “lyra-plus-ops” workflow
3. Click “Run workflow” button
4. Choose branch and click “Run workflow”

Next Steps for Production

1. Implement Real Data Sources in backend/make_release.py:
   • Integrate e-Tariff Portal API
   • Add UNCTAD TRAINS data fetching
   • Connect to OEC Observatory API
   • Implement World Bank data integration
2. Add Error Handling:
   • Email notifications on workflow failure
   • Slack/Discord webhook integration
   • Retry logic for failed API calls
3. Enhance Monitoring:
   • Add metrics collection
   • Create dashboard for data freshness
   • Monitor API response times
4. Security:
   • Add API authentication for health endpoint
   • Implement rate limiting
   • Secure API keys in GitHub Secrets

Architecture Notes

• React Frontend (not Next.js): The problem statement mentioned Next.js API routes, but this is a Create React App project. The health check was implemented as a FastAPI backend endpoint instead.
• Demo Data: All generated data is currently mock/demo data for testing purposes.
• Git Strategy: Generated data files are committed to the repository as they’re meant to be deployed with the application.
