4. HonestDog verification
- Upload a legible certificate (PDF or photo) per test in the breeder dashboard
- Certificate must show date, examining vet, and FCI/VDH logo
- Certificates older than 36 months are flagged as stale
- We extract the results from each upload using AI and check them for consistency with the dog's profile — the profile tile then shows 'verified'
