+**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.

+| 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 |

+| Context cancellation | ✅ PASS |
+| Unbuffered channels | ⚠️ 2 found |
+| Message handlers | 66 types handled |
+
+**CMD Goroutines without recovery:** 6 (in cmd/ - non-TUI code)
