## 📊 Current Test Coverage

**Overall Project Coverage**: ~17.5%

### Package-Level Coverage:
| Package | Coverage | Status |
|---------|----------|--------|
| `internal/validator` | 98.6% | ✅ Excellent |
| `internal/models` | 31.7% | 🟡 Good foundation |
| `internal/middleware` | 25.8% | 🟡 Good foundation |
| `internal/handlers` | 8.8% | 🟡 Infrastructure ready |
| `internal/cache` | 0.0% | ⚪ Not started |
| `internal/config` | 0.0% | ⚪ Not started |
| `internal/pdf` | 0.0% | ⚪ Not started |
| `internal/templates` | 0.0% | ⚪ Not started |
| `internal/testutil` | 0.0% | ⚪ Utility package (expected) |

**Note**: The infrastructure is complete and ready for expansion. Subsequent tasks will increase coverage toward the 70%+ goal.
