# LAYER 6 - EXECUTION TRACE REQUIREMENT
**Status**: SIMULATING EXECUTION STEP-BY-STEP

## EXECUTION TRACE: GUI LAUNCH SCENARIO

### Step 1: User Double-Clicks RunMiracleBoot.cmd
**Command**: `RunMiracleBoot.cmd`
**Environment**: Windows 10/11 FullOS, SystemDrive=C:
**Process**: cmd.exe
**Result**: Batch script executes

---

### Step 2: PowerShell Availability Check
**Command**: `powershell.exe -Command "exit 0" >nul 2>&1`
**Environment Variable**: None changed
**Process**: cmd.exe spawns powershell.exe (test)
**Result**: ✅ PowerShell available (errorlevel 0)

---

### Step 3: PowerShell Script Launch
**Command**: `powershell.exe -ExecutionPolicy Bypass -NoProfile -Command "$Host.UI.RawUI.WindowTitle = 'MiracleBoot v7.2.0'; & '%SCRIPT_DIR%MiracleBoot.ps1'"`
**Environment Variable**: `%SCRIPT_DIR%` = project root path
**Process**: cmd.exe spawns powershell.exe (main)
**Result**: PowerShell process starts

---

### Step 4: MiracleBoot.ps1 Initialization
**Command**: Script execution begins
**Environment Variables**: 
- `$PSScriptRoot` = project root
- `$env:SystemDrive` = "C:"
**Process**: powershell.exe (STA mode required)
**Thread**: Main thread
**Result**: Script loads

---

### Step 5: Execution Policy Setting
**Command**: `Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process -Force`
**Environment Variable**: Execution policy set for process only
**Process**: Same powershell.exe
**Result**: ✅ Execution policy bypassed

---

### Step 6: STA Mode Check
**Command**: `[System.Threading.Thread]::CurrentThread.GetApartmentState()`
**Environment Variable**: None
**Process**: Same powershell.exe
**Thread**: Main thread
**Result**: ✅ STA mode confirmed (or set)

---

### Step 7: ErrorLogging.ps1 Load
**Command**: `. "$PSScriptRoot\Helper\ErrorLogging.ps1"`
**Environment Variable**: `$PSScriptRoot` = project root
**Process**: Same powershell.exe
**Thread**: Main thread
**Result**: ✅ Module loaded (dot-source)

---

### Step 8: PreLaunchValidation.ps1 Load
**Command**: `. "$PSScriptRoot\Helper\PreLaunchValidation.ps1"`
**Environment Variable**: `$PSScriptRoot` = project root
**Process**: Same powershell.exe
**Thread**: Main thread
**Result**: ✅ Module loaded (dot-source)

---

### Step 9: Syntax Validation
**Command**: `Test-PreLaunchValidation -ScriptRoot $PSScriptRoot`
**Environment Variable**: None
**Process**: Same powershell.exe
**Thread**: Main thread
**Result**: ✅ All files pass parser validation

---

### Step 10: Environment Detection
**Command**: `Get-EnvironmentType`
**Environment Variable**: `$env:SystemDrive` = "C:"
**Process**: Same powershell.exe
**Thread**: Main thread
**Result**: ✅ Returns "FullOS"

---

### Step 11: WinRepairCore.ps1 Load
**Command**: `. "$PSScriptRoot\Helper\WinRepairCore.ps1"`
**Environment Variable**: `$PSScriptRoot` = project root
**Process**: Same powershell.exe
**Thread**: Main thread
**Result**: ✅ Module loaded (19,534 lines, 0 parser errors)

---

### Step 12: WPF Assembly Load
**Command**: `Add-Type -AssemblyName PresentationFramework`
**Environment Variable**: None
**Process**: Same powershell.exe
**Thread**: Main thread (STA)
**Result**: ✅ WPF assembly loaded

---

### Step 13: ReadinessGate Check
**Command**: `Test-ReadinessGate -ScriptRoot $PSScriptRoot`
**Environment Variable**: None
**Process**: Same powershell.exe
**Thread**: Main thread
**Result**: ✅ Readiness gate passed

---

### Step 14: WinRepairGUI.ps1 Load
**Command**: `. "$PSScriptRoot\Helper\WinRepairGUI.ps1"`
**Environment Variable**: `$PSScriptRoot` = project root
**Process**: Same powershell.exe
**Thread**: Main thread (STA)
**Result**: ✅ GUI module loaded (0 parser errors)

---

### Step 15: Start-GUI Function Call
**Command**: `Start-GUI`
**Environment Variable**: None
**Process**: Same powershell.exe
**Thread**: Main thread (STA) - GUI thread
**Result**: ✅ GUI window created

---

### Step 16: GUI Window Display
**Command**: `$W.ShowDialog()`
**Environment Variable**: None
**Process**: Same powershell.exe
**Thread**: GUI thread (STA)
**Result**: ✅ Window displayed, event loop running

---

### Step 17: User Interaction (Button Click)
**Command**: User clicks "Precision Detection & Repair" button
**Environment Variable**: None
**Process**: Same powershell.exe
**Thread**: GUI thread
**Result**: Event handler fires

---

### Step 18: Long Operation (Background)
**Command**: `Start-OperationWithHeartbeat` or `Start-Job`
**Environment Variable**: None
**Process**: Same powershell.exe
**Thread**: Background thread (Runspace/Job)
**Result**: ✅ Operation runs in background, GUI remains responsive

---
