# 📋 DBBACKUP VALIDATION SUMMARY

**Date:** 2026-02-03  
**Version:** 5.7.1

---

## ✅ CODE QUALITY

| Check | Status |
|-------|--------|
| go build | ✅ PASS |
| go vet | ✅ PASS |
| golangci-lint | ✅ PASS (0 issues) |
| staticcheck | ✅ PASS |

---

## ✅ TESTS

| Check | Status |
|-------|--------|
| Unit tests | ✅ PASS |
| Race detector | ✅ PASS (no data races) |
| Test coverage | 7.5% overall |

**Coverage by package:**
- `internal/validation`: 87.1%
- `internal/retention`: 49.5%
- `internal/security`: 43.4%
- `internal/crypto`: 35.7%
- `internal/progress`: 30.9%

---

## ⚠️ SECURITY (gosec)

| Severity | Count | Notes |
|----------|-------|-------|
| HIGH | 362 | Integer overflow warnings (uint64→int64 for file sizes) |
| MEDIUM | 0 | - |
| LOW | 0 | - |

**Note:** HIGH severity items are G115 (integer overflow) for file size conversions. These are intentional and safe as file sizes never approach int64 max.

## 📊 COMPLEXITY ANALYSIS

**High complexity functions (>20):**

| Complexity | Function | File |
|------------|----------|------|
| 101 | RestoreCluster | internal/restore/engine.go |
| 61 | runFullClusterRestore | cmd/restore.go |
| 57 | MenuModel.Update | internal/tui/menu.go |
| 52 | RestoreExecutionModel.Update | internal/tui/restore_exec.go |
| 46 | NewSettingsModel | internal/tui/settings.go |

**Recommendation:** Consider refactoring top 3 functions.

## 🖥️ TUI VALIDATION

| Check | Status |
|-------|--------|
| Goroutine panic recovery (TUI) | ✅ PASS |
| Program.Send() nil checks | ✅ PASS (0 issues) |
| Context cancellation | ✅ PASS |
| Unbuffered channels | ⚠️ 2 found |
| Message handlers | 66 types handled |

**CMD Goroutines without recovery:** 6 (in cmd/ - non-TUI code)
