🔄 Data Flow Verification

Create Restaurant Flow

POST /restaurants
→ Create with: healthScore: 0, isCertified: false, certificationLevel: NONE
→ Invalidate caches
✅ Complete

Add Certification Flow

POST /:id/certifications
→ Create cert
→ Fetch all active certs
→ Calculate average health score
→ Determine level from score
→ Update restaurant
→ Invalidate: certified-restaurants:*, restaurants:*, restaurant:{id}
✅ Complete

Filter Certified Flow

GET /certified?minHealthScore=70
→ Check cache
→ Query: isActive=true, isCertified=true, healthScore≥70
→ Cache for 30 min
✅ Complete

Revoke Certification Flow

DELETE /:id/certifications/:certId
→ Mark as inactive
→ Recalculate health score
→ Recalculate certification level
→ Update restaurant
→ Invalidate caches
✅ Complete
