# FUTURE FEATURES: Professional Windows Boot Repair Methodology

**Status:** PARKED FOR FUTURE IMPLEMENTATION  
**Priority:** HIGH  
**Timeline:** Post-v7.2 (v8.0 or later)  
**Complexity:** EXPERT-LEVEL (Microsoft Technician Grade)

---

## Executive Summary

This document outlines advanced boot repair capabilities that align with the diagnostic and repair strategies employed by Microsoft technicians and advanced IT professionals. These features would enable MiracleBoot to handle severe boot failures like INACCESSIBLE_BOOT_DEVICE (Stop 0x7B) with the same systematic, layer-by-layer approach used by professional support engineers.

Rather than providing generic recovery options, MiracleBoot would become a **true professional boot repair tool** that:
- Systematically identifies which phase of boot is failing
- Performs targeted root cause analysis
- Applies surgical fixes without full OS reinstallation
- Provides kernel-level debugging capabilities
- Preserves user data throughout the process

---

## Why This Matters

### Current State (v7.2)
- MiracleBoot handles common boot issues
- Recovery is limited to built-in Windows tools
- Advanced failures require professional IT support

### Target State (v8.0+)
- MiracleBoot becomes professional-grade
- Can handle advanced boot architecture issues
- Reduces need for expensive IT support
- Enables data preservation in severe failures

---

## THE CORE MINDSET: Microsoft Technician Methodology

> **Microsoft engineers do not troubleshoot symptoms. They prove invariants.**

This is the foundation of v8.0+ approach. Rather than guessing what's wrong, MiracleBoot will systematically prove the state of the system layer by layer.

### Core Assumptions
- Firmware lies
- Tools lie
- Setup lies
- Recovery lies
- **Only state transitions matter**

### The Mission
Move the system from:
- ❌ "unbootable"
- to ✓ "meets Setup's internal health contract"

**Key insight:** Booting is optional. Upgrade eligibility is the real win.

---

## THE 7-LAYER DIAGNOSTIC FRAMEWORK

This is how Microsoft technicians diagnose boot failures. MiracleBoot v8.0+ will implement this systematically.

### LAYER 1: HARD REALITY CHECK (No Windows Involved)

**Goal:** Prove hardware + firmware reality without relying on Windows

**Questions Answered:**
1. Does firmware expose the storage device?
2. Does firmware expose it consistently?
3. Is firmware behavior deterministic?

**Verification Checklist:**
```powershell
function Test-Layer1-HardwareReality {
    # UEFI mode verification (no CSM unless forced)
    # - Check if UEFI is enabled
    # - Check if Secure Boot matches install configuration
    
    # Secure Boot state consistency
    # - Current state (on/off is fine)
    # - Installed OS expectation
    # - Mismatch = STOP (hardware first)
    
    # Storage controller mode validation
    # - Firmware mode (AHCI, IDE, RAID, SCSI)
    # - Installation historical records
    # - Mismatch = #1 cause of 0x7B errors
    
    # PCIe lane stability
    # - NVMe detection consistency
    # - No drive disappearing across boots
    # - No disk number changes
    
    # DECISION POINT:
    # If firmware is unstable → STOP
    # If drive appears/disappears → STOP
    # If storage mode mismatched → STOP
    # Otherwise → proceed to Layer 2
}
```

**Critical Rule:** If the drive disappears, changes disk number, or appears intermittently:
- STOP all Windows troubleshooting
- Hardware or firmware problem must be fixed first
- No exceptions

### LAYER 2: STORAGE STACK TRUTH (The #1 Money Maker)

**Goal:** Prove the entire storage chain works offline

**The Contract Chain:**
```
Firmware → Controller → Driver → Class Driver → Volume Manager → Mount Manager
```

**Verification Checklist:**
```powershell
function Test-Layer2-StorageStack {
    # Check bottom-up (offline analysis preferred)
    
    # Storage controller driver verification
    # - Does driver exist in System32\drivers?
    # - Does driver exist in DriverStore?
    # - Is driver digitally signed?
    # - Is driver correct architecture (x64/x32)?
    
    # Registry validation
    # - Start type = 0 (BOOT - critical)
    # - Correct driver group assignment
    # - No orphan filter drivers blocking attach
    
    # Key insight:
    # Missing disk ≠ missing disk
    # Missing disk = missing language between OS and controller
    
    # DECISION POINT:
    # If driver missing or wrong start type → can be fixed
    # If controller filter is blocking → can be removed
    # If driver stack is healthy → proceed to Layer 3
}
```

**Critical Rule:** Do not rely on Device Manager. Ever. Analyze registry and driver store offline.

**Most Common Fix Here:** Storage mode mismatch (AHCI vs RAID) blocking driver load.

### LAYER 3: BOOT CHAIN FORENSICS (No Blind Rebuilds)

**Goal:** Map and validate the entire boot path

**The Complete Path:**
```
UEFI Firmware
    ↓
EFI System Partition (ESP)
    ↓
Windows Boot Manager
    ↓
Boot Configuration Data (BCD)
    ↓
Winload.efi/Winload.exe
    ↓
Windows NT Kernel
    ↓
Storage Attachment (Root device)
```

**Verification Checklist:**
```powershell
function Test-Layer3-BootChainForensics {
    # Prove, not assume
    
    # EFI Partition validation
    # - GUID is correct {C12A7328-F81F-11D2-BA4B-00A0C93EC93B}
    # - Partition is referenced by firmware
    # - Partition is readable
    
    # BCD validation
    # - Points to correct volume by offset (not just letter)
    # - Winload path matches OS location
    # - No stale identifiers or orphaned entries
    
    # Boot Manager validation
    # - Can locate and parse BCD
    # - All referenced objects exist
    # - No circular references
    
    # Critical insight:
    # bootrec /rebuildbcd can write a "syntactically correct" broken reality
    # Do not use it blindly
    
    # DECISION POINT:
    # If boot chain is intact → proceed to Layer 4
    # If BCD corrupted → rebuild with verification
    # If ESP missing → attempt recovery from partition backup
}
```

**Critical Rule:** Verify everything before using bootrec or bcdedit commands. They can create syntactically correct but functionally broken configurations.

### LAYER 4: OFFLINE REGISTRY SURGERY 🧠

**Goal:** Audit and repair the Windows registry offline (where the real expertise is)

**Critical Areas to Audit:**
```powershell
function Test-Layer4-OfflineRegistry {
    # Load SYSTEM hive offline and audit
    
    # Boot-start drivers
    # - What drivers are marked BOOT?
    # - Are they all present and valid?
    # - Any drivers from old hardware?
    
    # Storage services
    # - Disk and volume managers healthy?
    # - Class drivers correct?
    # - Filters properly ordered?
    
    # Pending operations
    # - Incomplete updates?
    # - Orphaned component store entries?
    # - Pending reboots from failed updates?
    
    # Last known good control set
    # - Is it actually good?
    # - Can it be reverted to?
    
    # Critical checks:
    # - Drivers marked DEMAND instead of BOOT (won't load)
    # - Old controller drivers still enabled (conflicts)
    # - Update remnants blocking normal load
    # - Orphaned filter drivers (blocks everything)
    
    # The magic formula:
    # If kernel loads but root device won't mount → registry mismatch
    # This layer fixes it
    
    # DECISION POINT:
    # If registry is clean → proceed to Layer 5
    # If registry has issues → fix only what's necessary
    # If multiple issues → Layer 5 may override (Setup can rebuild)
}
```

**Critical Insight:** This is where the high hourly rates come in. Offline registry analysis requires deep Windows knowledge.

### LAYER 5: SETUP ENGINE OVERRIDE THINKING 🔥

**Goal:** Understand what Setup requires and make the system compliant

**The Secret Most People Miss:** Microsoft trusts Setup more than the installed OS.

**If Setup says "no", investigate WHY Setup says no.**

**Verification Checklist:**
```powershell
function Test-Layer5-SetupCompliance {
    # Setup is more powerful than Windows
    # If Setup runs → Windows lives
    # If Setup refuses → Windows is dead even if it boots
    
    # Inspect critical Setup indicators
    
    # Panther logs
    # - What did Setup detect?
    # - What did Setup reject?
    # - What errors occurred?
    
    # Component Store (CBS) health
    # - Is CBS working?
    # - Are components corrupt?
    # - Can Setup access component store?
    
    # Compatibility database
    # - Does current OS version match installed?
    # - Is Edition compatible?
    # - Are build numbers consistent?
    
    # Pending operations
    # - Any pending reboot from failed updates?
    # - Any pending operations Setup can't complete?
    # - Incomplete servicing stack?
    
    # The key question:
    # "What single invariant is blocking Setup?"
    
    # Because:
    # Setup can rebuild almost anything
    # But only if ONE critical invariant is met
    
    # DECISION POINT:
    # If Setup runs → proceed to Layer 6 (guided recovery)
    # If Setup refuses → identify blocking invariant
    # If blocking invariant is from Layer 1-4 → fix it
}
```

### LAYER 6: FORCED REALITY ALIGNMENT

**Goal:** Choose the path that makes the system compliant

**Three Options:**

#### Path A: Match Firmware to OS
- Re-enable old controller modes in BIOS
- Revert Secure Boot settings
- Let OS boot "as originally installed"
- **Best if:** BIOS was recently changed

#### Path B: Teach OS the New Reality
- Inject correct drivers for current firmware
- Fix registry start order
- Neutralize conflicting filters
- **Best if:** Hardware upgrade happened

#### Path C: Hybrid "Bridge Boot"
- Minimal boot viability (just enough to start)
- Just enough to run Setup
- Setup overwrites and rebuilds
- **Best if:** Registry is severely damaged

**Verification Checklist:**
```powershell
function Test-Layer6-RealityAlignment {
    # This avoids reinstalls without lying to Setup
    
    # Evaluate which path is best
    
    # Path A: Firmware alignment
    if (BIOS_WasRecentlyChanged) {
        # Revert BIOS to match OS
        # Let OS boot normally
    }
    
    # Path B: Driver injection
    else if (HardwareWasUpgraded) {
        # Inject drivers for new hardware
        # Fix registry to recognize drivers
        # Let OS boot with new hardware
    }
    
    # Path C: Bridge boot + Setup
    else if (RegistrySeverelyDamaged) {
        # Create minimal viable boot
        # Run Setup to rebuild everything
        # Setup handles all repairs
    }
    
    # DECISION POINT:
    # Choose the path that requires least disruption
    # Each path has specific prerequisites
}
```

### LAYER 7: CLEAN HANDOFF TO SETUP (The Endgame)

**Goal:** Get Setup running and let it take over

**Why Setup Wins:**
- Rewrites BCD correctly
- Rebuilds driver stack
- Fixes component store
- Preserves programs and files
- Fixes what manual repair cannot

**Verification Checklist:**
```powershell
function Test-Layer7-SetupHandoff {
    # Prepare system for Setup to take over
    
    # Prerequisites met?
    # - Layer 1-6 have cleared obstacles
    # - System is in valid starting state
    # - Setup prerequisites are met
    
    # Launch Setup with correct parameters
    # - /Repair mode
    # - /COMPAT mode if needed
    # - /InstallDriver if drivers needed
    
    # Monitor Setup progress
    # - Does Setup accept the system?
    # - Is Setup making progress?
    # - Are errors recoverable?
    
    # Success condition:
    # if (Setup launches and proceeds)
    #     Case closed
    #     Machine saved
    #     Windows lives
}
```

**Critical Success Factor:** If Setup launches successfully, the machine is saved. Everything else is just Setup doing its job.

## Implementation Approach: Layer-by-Layer

Instead of building random features, v8.0 will implement MiracleBoot as a **systematic diagnostic engine** that works through these layers:

1. **Layer 1 Tools:** Hardware reality verification
2. **Layer 2 Tools:** Storage stack analysis (offline)
3. **Layer 3 Tools:** Boot chain mapping and repair
4. **Layer 4 Tools:** Registry auditing and surgery
5. **Layer 5 Tools:** Setup compliance verification
6. **Layer 6 Tools:** Reality alignment strategies
7. **Layer 7 Tools:** Setup orchestration

Each layer is optional - users can drill down to the depth needed.

## Architecture Overview

### Boot Phase Identification

The Windows boot process occurs in four distinct phases:

#### 1. PreBoot Phase
**Indicators:** Hard drive light inactive, NumLock toggle unresponsive  
**Likely Causes:** Hardware-level problems, BIOS issues, memory failure  
**MiracleBoot Action:** Hardware diagnostic recommendations

#### 2. Boot Loader Phase
**Indicators:** Black screen with cursor, or specific error codes during startup  
**Likely Causes:** Corrupted Boot Configuration Data (BCD), missing bootmgr, corrupted boot sector  
**MiracleBoot Action:** Automated BCD repair, bootmgr recovery, sector repair

#### 3. Kernel Phase
**Indicators:** INACCESSIBLE_BOOT_DEVICE (0x7B), other BSOD errors  
**Likely Causes:** Storage controller mode mismatch, missing drivers, corrupted system files  
**MiracleBoot Action:** Driver injection, storage mode adjustment, DISM repair

#### 4. User Session Phase
**Indicators:** Desktop loads then crashes, services fail, application crashes  
**Likely Causes:** Corrupted registry, driver conflicts, pending updates  
**MiracleBoot Action:** Registry repair, driver filtering, pending update removal

### Diagnostic Engine

```powershell
function Diagnose-BootFailure {
    <#
    Systematic elimination to isolate the exact boot phase where failure occurs
    #>
    
    # Phase 1: PreBoot Diagnostics
    if (Test-PreBootHardware) {
        # Hardware is fine
    } else {
        # Hardware issue - recommend hardware diagnostics
        return "PreBoot_Hardware"
    }
    
    # Phase 2: Boot Loader Check
    if (Test-BootLoaderIntegrity) {
        # Boot loader is fine
    } else {
        # BCD or bootmgr corrupted
        return "BootLoader_BCD"
    }
    
    # Phase 3: Kernel Phase Check
    if (Test-KernelLoadable) {
        # Kernel loads
    } else {
        # Kernel phase failure
        return "Kernel_Failure"
    }
    
    # Phase 4: Session Check
    if (Test-UserSessionStable) {
        # All systems operational
        return "NoIssue"
    } else {
        return "Session_Failure"
    }
}
```

## Feature 1: Systematic Boot Diagnostics

### Hardware-Level Diagnostics

```powershell
# Run manufacturer diagnostics non-invasively
function Start-HardwareDiagnostics {
    param([string]$Manufacturer = "Auto")
    
    <#
    Supported:
    - Dell: Press F12 at startup
    - HP: Press F2 at startup
    - Lenovo: Press F10 at startup
    - Generic: Manufacturer tools (BootCD, MemTest86)
    #>
    
    # Detect hardware automatically
    $hwInfo = Get-WmiObject Win32_ComputerSystem
    
    # Generate diagnostic boot disk if needed
    # Create bootable USB with manufacturer diagnostics
    # Guide user through boot sequence
    # Parse results and provide recommendations
}
```

### Boot Logging Capture

```powershell
# Enable advanced boot logging
function Enable-BootLogging {
    <#
    Enables Startup Settings logging to capture:
    - Which drivers load successfully
    - Where boot process stalls
    - System resource status at failure point
    #>
    
    # Modify boot configuration for enhanced logging
    bcdedit /set bootdebug on
    bcdedit /set bootlog on
    
    # Next boot creates ntbtlog.txt with complete driver sequence
    # Analysis can identify exact failure point
}

function Analyze-BootLog {
    param([string]$LogPath = "C:\Windows\ntbtlog.txt")
    
    # Parse boot log to identify:
    # 1. Successfully loaded drivers
    # 2. Where boot process hung
    # 3. Driver load order
    # 4. System state at failure
    
    $log = Get-Content $LogPath
    
    # Return detailed analysis
    return @{
        SuccessfulDrivers = @()
        FailedDrivers = @()
        StallPoint = ""
        Recommendations = @()
    }
}
```

## Feature 2: Root Cause Analysis - Storage Controller Issues

### AHCI/Storage Mode Detection

```powershell
function Get-StorageControllerMode {
    <#
    Identifies if BIOS storage mode matches Windows installation
    Common issue: AHCI in BIOS, but RAID drivers expected by Windows
    This causes INACCESSIBLE_BOOT_DEVICE errors
    #>
    
    # Query current BIOS mode
    $biosMode = (Get-WmiObject -Class Win32_DiskDrive).InterfaceType
    # Possible values: AHCI, IDE, RAID, SCSI
    
    # Query what Windows drivers are loaded
    $loadedDrivers = Get-WmiObject -Class Win32_PnPDevice | Where-Object {$_.ClassGuid -eq "{4d36e96a-e325-11ce-bfc1-08002be10318}"}
    
    # Compare and identify mismatch
    if ($biosMode -eq "AHCI" -and $loadedDrivers.Name -match "RAID") {
        return "MODE_MISMATCH"  # This is the problem!
    }
    
    return "MODE_OK"
}

function Fix-StorageModeMismatch {
    <#
    Professional fix without reinstalling Windows:
    1. Boot into Safe Mode (forces generic driver loading)
    2. Switch BIOS to correct mode
    3. Let Windows load proper drivers
    4. Restart normally
    #>
    
    Write-Host "Storage mode mismatch detected. Initiating professional fix..."
    
    # Step 1: Set next boot to Safe Mode
    bcdedit /set "{current}" safeboot minimal
    
    Write-Host "Next restart will boot into Safe Mode"
    Write-Host "Windows will load generic storage drivers"
    Write-Host "Restart computer and follow BIOS instructions:"
    Write-Host "  1. Change Storage Mode to AHCI"
    Write-Host "  2. Save and exit BIOS"
    Write-Host "  3. Windows will load proper drivers"
    Write-Host "  4. Return to normal boot mode in 10 minutes"
    
    # Prompt for restart
    $restart = Read-Host "Restart now? (Y/N)"
    if ($restart -eq "Y") {
        Restart-Computer -Force
    }
}
```

## Feature 3: Advanced BCD and Boot Repair

### Intelligent BCD Reconstruction

```powershell
function Repair-BootConfigurationData {
    <#
    Professional BCD repair sequence:
    1. Backup existing BCD
    2. Scan for Windows installations
    3. Validate each BCD entry
    4. Rebuild if corrupted
    #>
    
    param([string]$SystemDrive = "C:")
    
    Write-Host "Initiating BCD repair sequence..."
    
    # Step 1: Backup corrupted BCD
    $timestamp = Get-Date -Format "yyyyMMdd_HHmmss"
    $backupPath = "C:\boot\bcd_backup_$timestamp"
    
    Copy-Item "C:\boot\bcd" -Destination $backupPath -Force
    Write-Host "Backed up corrupted BCD to: $backupPath"
    
    # Step 2: Scan for Windows installations
    Write-Host "Scanning for Windows installations..."
    $scanResult = & bootrec /ScanOS
    
    # Step 3: Attempt repairs in order
    Write-Host "Attempting repairs..."
    & bootrec /FixMBR
    & bootrec /FixBoot
    & bootrec /RebuildBCD
    
    Write-Host "BCD repair complete. Please restart to test."
    
    return $scanResult
}

function Validate-BCDEntry {
    param([string]$EntryName)
    
    <#
    Validate individual BCD entries for correctness
    Check for:
    - Valid device references
    - Proper OS path
    - Required boot parameters
    - File existence
    #>
    
    $entry = bcdedit /enum | Where-Object {$_ -match $EntryName}
    
    # Validate each property
    $isValid = $true
    if (-not (Test-Path ($entry.path))) {
        Write-Host "ERROR: OS path not found" -ForegroundColor Red
        $isValid = $false
    }
    
    return $isValid
}

function Repair-BootManagerFile {
    <#
    If bootmgr is corrupted, copy from System Reserved partition
    #>
    
    param(
        [string]$SourceDrive = "C:",
        [string]$TargetPartition = "System Reserved"
    )
    
    # Locate System Reserved partition
    $sysReserved = Get-Partition | Where-Object {$_.Type -eq "System"}
    
    # Copy bootmgr from Windows partition
    $bootmgrSource = "$SourceDrive\bootmgr"
    $bootmgrTarget = "$($sysReserved.DriveLetter):\bootmgr"
    
    Copy-Item $bootmgrSource -Destination $bootmgrTarget -Force
    Write-Host "Restored bootmgr to System Reserved partition"
}
```

## Feature 4: Offline System Repair

### DISM Offline Repair

```powershell
function Repair-WindowsImageOffline {
    <#
    For systems that cannot boot or enter WinRE:
    1. Move drive to another computer
    2. Use DISM to scan offline image
    3. Repair corrupted system files
    4. Return drive to original computer
    #>
    
    param(
        [string]$ImagePath = "D:\",  # Mounted offline Windows partition

    Write-Host "Attempting repair using media source..."
    DISM /Image:$ImagePath /Cleanup-Image /RestoreHealth /Source:$MediaPath\Sources\install.wim
    
    Write-Host "Image repair complete. Verify on original computer."
}

function Repair-SystemFilesOffline {
    <#
    Offline System File Checker (SFC) for unbootable systems
    #>
    
    param(
        [string]$WindowsPath = "C:\Windows",
        [string]$BootPath = "C:"
    )
    
    Write-Host "Starting offline System File Checker..."
    SFC /Scannow /OffBootDir=$BootPath /OffWinDir=$WindowsPath
    
    Write-Host "System file repair complete."
}
```

### Offline Registry Editing

```powershell
function Remove-ProblematicDriverFilter {
    <#
    If a third-party driver is blocking boot:
    1. Load registry hive offline
    2. Find problematic driver filter
    3. Remove filter entry
    4. Unload hive
    5. Restart
    #>
    
    param(
        [string]$RegistryHivePath = "C:\Windows\System32\config\SYSTEM",
        [string]$ProblematicDriver = ""
    )
    
    Write-Host "Loading registry hive offline..."
    reg load HKLM\OFFLINE $RegistryHivePath
    
    # Find upper and lower filter values
    $filters = reg query "HKLM\OFFLINE\ControlSet001\Control\Class" /s | Where-Object {$_ -match "UpperFilters|LowerFilters"}
    
    foreach ($filter in $filters) {
        if ($filter -match $ProblematicDriver) {
            Write-Host "Found problematic filter: $filter"
            # Remove it
            reg delete "HKLM\OFFLINE\ControlSet001\Control\Class" /v "ProblematicFilter" /f
        }
    }
    
    Write-Host "Unloading registry hive..."
    reg unload HKLM\OFFLINE
    
    Write-Host "Driver filter removed. Restart to test."
}
```

## Feature 5: Kernel-Mode Debugging

### WinDbg Integration

```powershell
function Enable-KernelDebug {
    <#
    For critical boot failures that can't be resolved by standard tools:
    Set up kernel debugging with WinDbg for advanced analysis
    
    Requires:
    - Windows Debugger (WinDbg) on host machine
    - Network or serial connection between machines
    - TCP port 50000 or serial COM port
    #>
    
    param(
        [string]$DebuggerIP = "192.168.1.100",

    Write-Host "  Port: $Port"
    Write-Host "  Key: $Key"
    Write-Host ""
    Write-Host "Restart this computer to begin debugging."
}

function Analyze-MemoryDump {
    <#
    When a BSOD occurs, Windows creates a minidump file
    This can be analyzed to identify the faulting driver
    #>
    
    param([string]$DumpPath = "C:\Windows\Minidump\")
    
    # Get most recent dump file
    $latestDump = Get-ChildItem $DumpPath -Filter "*.dmp" | Sort-Object LastWriteTime -Descending | Select-Object -First 1
    
    if ($latestDump) {

- [ ] BCD validator (not just syntax, but semantic correctness)
- [ ] Boot manager integrity checker
- [ ] Winload path verifier
- [ ] Boot chain mapper (visual diagram)
- [ ] Safe BCD rebuilder (with verification)

**Entry Point:** If driver stack OK but boot fails → fix here

### Phase 4: Layer 4 - Offline Registry Surgery (Months 7-8)

**Goal:** Audit and repair Windows registry offline

**Deliverables:**
- [ ] Boot-start driver auditor
- [ ] Critical registry section analyzer
- [ ] Control set health checker
- [ ] Update remnant detector
- [ ] Orphaned filter driver remover
- [ ] Registry repair engine (surgical, not blind)

**Entry Point:** If kernel loads but root device won't mount → fix here

### Phase 5: Layer 5 - Setup Compliance Engine (Months 9-10)

**Goal:** Verify Setup requirements and identify blocking invariants

**Deliverables:**
- [ ] Panther log analyzer
- [ ] Component store (CBS) health checker
- [ ] Setup compatibility database validator
- [ ] Pending operation detector
- [ ] Blocking invariant identifier
- [ ] Setup readiness report

**Entry Point:** If all layers OK but Setup won't run → diagnose here

### Phase 6: Layer 6 - Reality Alignment Strategies (Months 11-12)

**Goal:** Choose optimal path (firmware alignment, driver injection, or bridge boot)

**Deliverables:**
- [ ] Firmware vs OS mismatch detector
- [ ] BIOS history analyzer
- [ ] Hardware upgrade detector
- [ ] Driver injection engine
- [ ] Bridge boot creator
- [ ] Reality alignment advisor (suggests best path)

**Entry Point:** If blocking invariant identified → select strategy here

### Phase 7: Layer 7 - Setup Orchestration (Months 13-14)

**Goal:** Orchestrate Setup to complete the repair

**Deliverables:**
- [ ] Setup launcher with correct parameters
- [ ] Setup progress monitor
- [ ] Setup error handler
