## 📋 Phase 4b: Health & Genetics (NEXT UP − v0.7.0)

> **Context:** Golden Retriever health clearances follow GRCA Code of Ethics and OFA/CHIC standards.
> This phase builds a structured, breed-aware health tracking system aligned with those requirements.

### Tier 1 — OFA Health Clearances *(Priority 1)* 🩺

The four GRCA-required clearances that must be on record in the public OFA database before breeding.

**Database (schema additions to `health_records` table):**
- [ ] Add `test_type` ENUM-style field: `hip_ofa`, `hip_pennhip`, `elbow_ofa`, `heart_ofa`, `heart_echo`, `eye_caer`, `thyroid_ofa`, `dna_panel`
- [ ] Add `result` field: `pass`, `fail`, `carrier`, `clear`, `excellent`, `good`, `fair`, `borderline`
- [ ] Add `ofa_number` VARCHAR — official OFA certification number
- [ ] Add `chic_number` VARCHAR — CHIC certification number (dog-level field on `dogs` table)
- [ ] Add `performed_by` VARCHAR — vet or specialist name
- [ ] Add `expires_at` DATE — for annually-renewed tests (eyes, heart)
- [ ] Add `document_url` VARCHAR — path to uploaded PDF/image
- [ ] Safe ALTER TABLE migration guards for all new columns

**API:**
- [ ] `GET /api/health/:dogId` — list all health records for a dog
- [ ] `POST /api/health` — create health record
- [ ] `PUT /api/health/:id` — update health record
- [ ] `DELETE /api/health/:id` — delete health record
- [ ] `GET /api/health/:dogId/clearance-summary` — returns pass/fail/missing for all 4 OFA tiers
- [ ] `GET /api/health/:dogId/chic-eligible` — returns boolean + missing tests

**UI Components:**
- [ ] `HealthRecordForm` modal — test type dropdown, result, OFA#, date, performed-by, expiry, document upload
- [ ] `HealthTimeline` component — chronological list of all health events per dog on DogDetail page
- [ ] `ClearanceSummaryCard` — shows OFA Hip / Elbow / Heart / Eyes status in a 2x2 grid with color badges (green=pass, yellow=expiring, red=missing/fail)
- [ ] `ChicStatusBadge` — amber badge on dog cards and DogDetail if CHIC number is on file
- [ ] Expiry alert: yellow badge on dog card if any annual test expires within 90 days; red if expired
- [ ] Document upload support (PDF/image) tied to individual health records

**Clearance Tiers Tracked:**
| Test | OFA Minimum Age | Renewal | Notes |
|---|---|---|---|
| Hip Dysplasia | 24 months | Once (final) | OFA eval or PennHIP |
| Elbow Dysplasia | 24 months | Once (final) | OFA eval |
| Cardiac (Heart) | 12 months | Annual recommended | Echo preferred over auscultation |
| Eyes (CAER) | 12 months | **Annual** | Board-certified ACVO ophthalmologist |
| Thyroid (OFA) | 12 months | Annual recommended | Bonus/Tier 2 |

**Complexity:** Medium | **Impact:** High | **User Value:** Excellent
**Estimated Time:** 8–10 hours

---

### Tier 2 — DNA Genetic Panel *(Priority 2)* 🧬

Embark or equivalent panel results per dog. Allows carrier × clear pairing without producing affected offspring.

**Database:**
- [ ] `genetic_tests` table: `id`, `dog_id`, `test_provider` (embark/optigen/etc), `test_name`, `result` (clear/carrier/affected), `test_date`, `document_url`, `created_at`
- [ ] Safe `CREATE TABLE IF NOT EXISTS` guard

**Golden Retriever Panel — Key Markers:**
- [ ] PRA1 (Progressive Retinal Atrophy type 1)
- [ ] PRA2 (Progressive Retinal Atrophy type 2)
- [ ] prcd-PRA (Progressive Rod-Cone Degeneration)
- [ ] ICH1 / ICH2 (Ichthyosis — very common in Goldens)
- [ ] NCL (Neuronal Ceroid Lipofuscinosis — fatal neurological)
- [ ] DM (Degenerative Myelopathy)
- [ ] MD (Muscular Dystrophy)
- [ ] GR-PRA1, GR-PRA2 (Golden-specific PRA variants)

**API:**
- [ ] `GET /api/genetics/:dogId` — list all genetic test results
- [ ] `POST /api/genetics` — add genetic result
- [ ] `PUT /api/genetics/:id` — update
- [ ] `DELETE /api/genetics/:id` — delete
- [ ] `GET /api/genetics/pairing-risk?sireId=&damId=` — returns at-risk combinations for a trial pairing

**UI Components:**
- [ ] `GeneticTestForm` modal — provider, marker, result (clear/carrier/affected), date, upload
- [ ] `GeneticPanelCard` on DogDetail — color-coded grid of all markers (green=clear, yellow=carrier, red=affected, gray=not tested)
- [ ] Pairing risk overlay on Trial Pairing Simulator — flag if sire+dam are both carriers for same marker
- [ ] "Not Tested" indicator on dog cards when no DNA panel on file

**Complexity:** Medium | **Impact:** High | **User Value:** Excellent
**Estimated Time:** 6–8 hours

---

### Tier 3 — Cancer Lineage & Longevity Tracking *(Priority 3)* 📊

Golden Retrievers have ~60% cancer mortality rate. Lineage-based cancer history is a major differentiator for responsible breeders.

**Database:**
- [ ] `cancer_history` table: `id`, `dog_id`, `cancer_type`, `age_at_diagnosis`, `age_at_death`, `cause_of_death`, `notes`, `created_at`
- [ ] Add `age_at_death` and `cause_of_death` optional fields to `dogs` table

**API:**
- [ ] `GET /api/health/:dogId/cancer-history`
- [ ] `POST /api/health/cancer-history`
- [ ] `GET /api/pedigree/:dogId/cancer-lineage` — walks ancestors and returns cancer incidence summary

**UI:**
- [ ] Longevity section on DogDetail — age at death, cause of death
- [ ] Cancer lineage indicator on Trial Pairing Simulator — "X of 8 ancestors had cancer history"
- [ ] Optional cancer history entry on DogForm

**Complexity:** Low-Medium | **Impact:** Medium | **User Value:** High (differentiator)
**Estimated Time:** 4–5 hours

---

### Tier 4 — Breeding Eligibility Checker *(Priority 4)* ✅

Automatic litter eligibility gate based on health clearance status of sire and dam.

**Logic:**
- [ ] Dog is "GRCA eligible" if: Hip OFA ✅ + Elbow OFA ✅ + Heart ✅ + Eyes (non-expired) ✅ + age ≥ 24 months
- [ ] Dog is "CHIC eligible" if all four tests are in OFA public database (CHIC number on file)
- [ ] Warning flags in Trial Pairing Simulator if sire or dam is missing required clearances
- [ ] Block litter creation (with override) if either parent fails eligibility check

**UI:**
- [ ] Eligibility badge on dog cards: `GRCA Eligible` (green) / `Incomplete` (yellow) / `Not Eligible` (red)
- [ ] Eligibility breakdown tooltip on hover — shows which tests are missing
- [ ] Pre-litter warning modal when creating a litter with non-eligible parents
- [ ] CHIC number field + verification note on DogDetail

**Complexity:** Low | **Impact:** High | **User Value:** Excellent
**Estimated Time:** 3–4 hours
