Write-Host "-"*70

Write-Host "`n1. SilentlyContinue on Set-ExecutionPolicy (Line 2)"
Write-Host "   - Failures hidden from user"
Write-Host "   - Script continues in wrong state"
Write-Host "   - Cascades to assembly load failures"

Write-Host "`n2. No Explicit STA Thread Enforcement"
Write-Host "   - Background jobs run in MTA"
Write-Host "   - WPF ShowDialog crashes on MTA thread"
Write-Host "   - No error handling to catch this"

Write-Host "`n3. ShowDialog() Has NO Try/Catch Wrapper"
Write-Host "   - Located at WinRepairGUI.ps1 line ~3978"
Write-Host "   - Threading failures cause hard crash"
Write-Host "   - No fallback to TUI"
Write-Host "   - No error logging"

Write-Host "`n4. Assembly Loading After SilentlyContinue Operation"
Write-Host "   - Execution policy failure not caught"
Write-Host "   - WPF load may work in degraded state"
Write-Host "   - Creates race condition at ShowDialog()"

Write-Host "`n5. XAML Parsing Not Fully Error-Handled"
Write-Host "   - Error logged but fallback incomplete"
Write-Host "   - No guarantee TUI loads on XAML failure"

Write-Host "`n6. Multiple Helper Scripts Not Pre-Validated"
Write-Host "   - WinRepairCore.ps1 - no existence check before dot-source"
Write-Host "   - WinRepairGUI.ps1 - no syntax validation"
Write-Host "   - Script crashes if files missing"

# ANTI-PATTERNS DETECTED
# ============================================================================

Write-Host "`n`n[ANTI-PATTERNS FOUND]" -ForegroundColor Red
Write-Host "-"*70

Write-Host "`n1. SilentlyContinue on Critical Initialization"
Write-Host "   Pattern: Set-ExecutionPolicy ... -ErrorAction SilentlyContinue"
Write-Host "   Risk: CRITICAL"

Write-Host "`n2. No STA Enforcement for WPF"
Write-Host "   Pattern: Start-GUI called directly without STA check"
Write-Host "   Risk: CRITICAL"

Write-Host "`n3. ShowDialog Without Try/Catch"
Write-Host "   Pattern: `$W.ShowDialog() | Out-Null"
Write-Host "   Risk: CRITICAL"

Write-Host "`n4. Large Null-Check Blocks (200+ lines)"
Write-Host "   Pattern: if (`$null -ne `$W) { ... many operations ... }"
Write-Host "   Risk: MEDIUM (poor error isolation)"

Write-Host "`n5. No File Existence Pre-Validation"
Write-Host "   Pattern: . `$scriptPath (without Test-Path first)"
Write-Host "   Risk: HIGH"
