---

### 6. Frontend ⚠️ ISSUE

```bash
GET /
```

**Response:** 500 Internal Server Error

**Root Cause:** nginx configuration has rewrite loop when redirecting to index.html

**Log:** 
```
[error] rewrite or internal redirection cycle while internally redirecting to "/index.html"
```

**Status:** Health probe passes (`/health` → 200), but root path fails.

**Fix Required:** Update nginx.conf in frontend Dockerfile or ConfigMap.

---

### 7. Prometheus Metrics ❌ ISSUE

```bash
GET /metrics
```

**Response:** 500 Internal Server Error (same nginx loop issue)

**Note:** The `/metrics` endpoint is defined in backend but the request routes through frontend nginx first.

**Fix:** Either:
1. Route `/metrics` to backend in Ingress
2. Fix nginx config to not redirect all paths

---

## Database Schema Verification

All required tables exist:
- ✅ users
- ✅ programs
- ✅ program_days
- ✅ exercises
- ✅ program_exercises
- ✅ workout_logs
- ✅ custom_workouts
- ✅ custom_workout_exercises

---

## Issues Found

### Critical (0)
None

### High (1)
1. **Frontend nginx rewrite loop** - Root path returns 500. Needs nginx.conf fix.

### Medium (1)
1. **Metrics endpoint inaccessible** - /metrics routes through frontend instead of backend.

### Low (0)
None

---

## Recommendations

1. **Fix frontend nginx.conf**
   ```nginx
   location / {
     try_files $uri $uri/ /index.html;
   }
   ```
   Should ensure index.html exists or handle SPA routing correctly.

2. **Add backend metrics route to Ingress**
   ```yaml
   - path: /metrics
     pathType: Prefix
     backend:
       service:
         name: gravl-backend
         port:
           number: 3000
   ```

3. **Consider adding /api/exercises/:id endpoint** - Currently only list and alternatives exist.

## Test Environment Details

| Component | Status | Version/Notes |
|-----------|--------|---------------|
| PostgreSQL | Running | PVC backed, 1ms response |
| Backend | Running | v2-staging image |
| Frontend | Running | nginx loop issue |
| Ingress | Working | Traefik, localhost:9080 |
| K8s Namespace | gravl-staging | All 3 pods healthy |

---

## Conclusion

**The core API functionality is working correctly.** Authentication, exercises, programs, and progression logic all function as expected. 

The frontend nginx configuration issue is a deployment bug, not an application bug. Once fixed, the frontend should serve the SPA correctly.

**Recommended next step:** Fix nginx.conf and redeploy frontend before production release.
