Data Retention: Indefinite (historical voting records)

Relationships

- POLITICIAN to PARTY: Many-to-One (politician belongs to one party at a time)

- POLITICIAN to VOTE: One-to-Many (politician casts many votes)

- BALLOT to VOTE: One-to-Many (ballot contains many votes)

- POLITICIAN to POLITICIAN_ROLE: One-to-Many (politician has multiple roles over time)

Data Classification Summary

- PUBLIC: Politician names, votes, documents (public record)

- INTERNAL: System IDs, timestamps, technical metadata

- CONFIDENTIAL: None

- RESTRICTED: None

Performance Considerations

- Votes table will grow large (millions of records), requires partitioning by year

- Full-text search on DOCUMENT requires Elasticsearch integration

- POLITICIAN queries often join with PARTY, consider denormalization for read performance

Decision Points

Validation Checks

- HTML validation

- CSS validation

- JavaScript linting

- Accessibility checks (WCAG 2.1 AA)

- Link validation

- Security header validation

Security Scan Thresholds

- Block deployment: Critical vulnerabilities

- Warning: High vulnerabilities (review required)

- Pass: Medium or lower vulnerabilities

Lighthouse Budget

- Performance: ≥ 90

- Accessibility: ≥ 95

- Best Practices: ≥ 95

- SEO: ≥ 95

Error Handling

All workflows include error handling:

- Detect error - Automated checks or manual report

- Log error - CloudWatch, GitHub Actions logs

- Notify - Slack/email notification

- Rollback (if deployed) - Revert to previous version

- Fix - Implement correction

- Verify - Test fix before re-deploying

Performance Considerations

- Parallel processing: Run security scan and Lighthouse audit in parallel

- Caching: Cache CloudFront invalidation to avoid rate limits

- Incremental builds: Only process changed files
