# Repair-Install Readiness Engine v1.0
## Implementation Guide for MiracleBoot v7.2.0+

---

## Overview

The **Repair-Install Readiness Engine** is a new orchestration module that bridges the gap identified in the ChatGPT analysis: while MiracleBoot excels at boot repair, WinPE awareness, and OS health restoration, it was **missing the final critical step** needed to guarantee in-place upgrade repair eligibility.

### The Problem It Solves

**Previous Workflow:**
```
Boot broken → Run repairs → "Hope it boots!" → User stuck with clean install
```

**New Workflow:**
```
Boot broken → Run repairs → Check eligibility → Normalize state → Safe to in-place upgrade
```

### Strategic Alignment

This implementation addresses multiple strategic priorities from FUTURE_ENHANCEMENTS.md:
- **Phase 1 (v7.2-v7.5)**: Foundation building — adding core recovery platform layer ✓
- **Phase 2 (v8.0)**: Enhancement — integrating intelligent decision logic ✓
- **Section 1.1**: Advanced BCD Management — complements boot repair ✓
- **Section 3.1**: Scripting & Automation — adds intelligent decision tree ✓

## Architecture

### Module: EnsureRepairInstallReady.ps1

**Purpose:** Ensure Windows is eligible for setup.exe repair-install mode (keeps apps + files)

**Key Functions:**

#### 1. `Invoke-CBSCleanup`
Normalizes Component Store state for setup compatibility:
- Clears RebootPending registry flags
- Purges PendingFileRenameOperations
- Validates component store integrity
- Runs dism /resetbase if needed

**When to use:** After primary boot repairs (SFC, DISM)

---

#### 2. `Test-SetupEligibility`
Verifies Windows meets setup.exe requirements:
- Offline registry validation (EditionID, InstallationType, CurrentBuild)
- Detects edition/build mismatches early
- Checks RebootPending flags
- Validates UBR (Update Build Revision) consistency

**When to use:** Diagnostic phase, before repairs

---

#### 3. `Repair-WinREMetadata`
Repairs Windows Recovery Environment metadata:
- Re-registers WinRE partition
- Validates ReAgent.xml
- Updates BCD recovery settings
- Ensures bootloadersettings are correct

**When to use:** When WinRE registration issues are detected

---

#### 4. `Test-SetupExeReadiness`
Pre-validates setup.exe requirements without running actual setup:
- Disk space check (10GB minimum)
- Antivirus status
- Network connectivity
- Power configuration
- Pending updates detection

**When to use:** Final validation before user launches setup.exe

---

#### 5. `Invoke-RepairInstallReadinessCheck` (Orchestrator)
Coordinates entire workflow:
1. Phase 1: Diagnostic checks
2. Phase 2: Auto-repair (optional)
3. Phase 3: Post-repair validation
4. Phase 4: Setup.exe pre-validation

Returns final recommendation status and detailed logs.

---

## Integration Points

### 1. MiracleBoot.ps1 (Orchestrator)
```powershell
# Added module sourcing
. "$PSScriptRoot\EnsureRepairInstallReady.ps1"
```
- Module is loaded alongside WinRepairCore.ps1
- Graceful fallback if module not available
- Functions available to GUI/TUI components

---

### 2. WinRepairGUI.ps1 (New Tab)
**Tab Name:** "Repair-Install Readiness"

**Components:**
- **Status Indicators:** 4 colored rectangles showing phase status
- **Action Buttons:**
  - "Run Readiness Check" — diagnostic only
  - "Run Check + Auto-Repair" — attempt fixes
  - "Export Report" — save results to file
- **Output Display:** Live color-coded status window (cyan = info, yellow = warning, red = error, green = success)

**Workflow:**
```
User clicks "Run Readiness Check"
  → Runs Test-SetupEligibility
  → Shows results with color coding
  → Updates status indicators
  
User clicks "Run Check + Auto-Repair"
  → Runs all phases
  → Attempts CBS cleanup
  → Repairs WinRE metadata
  → Re-validates eligibility
  → Shows final recommendation
```

---

### 3. WinRepairTUI.ps1 (New Menu Option #6)
**Menu Option:** "6) Repair-Install Readiness Check" (moved to prominent position)

**Submenu:**
```
(1) Check Only
(2) Check + Auto-Repair
(Q) Return to Menu
```

**Console Output:**
- Real-time status with phase headers
- Color-coded messages (same as GUI)
- Final recommendation at end
- Prompts for confirmation before auto-repairs

---

## Return Value Structure

### Invoke-RepairInstallReadinessCheck Output
```powershell
@{
    StartTime = [DateTime]
    EndTime = [DateTime]
    OverallStatus = "Success|Warning|Failed"
    FinalRecommendation = "READY_FOR_REPAIR_INSTALL|READY_WITH_WARNINGS|NOT_READY|ERROR"
    Steps = @(
        @{ 
            Step = "Setup Eligibility Check"
            Result = [Hashtable with IsEligible, Blockers, Warnings]
        },
        @{ 
            Step = "CBS Cleanup"
            Result = [Hashtable with RebootPendingCleared, etc.]
        },
        # ... more steps
    )
}
```

---

## Usage Scenarios

### Scenario 1: WinPE Environment
```powershell
# Admin mounting Windows at X:\Windows
.\MiracleBoot.ps1  # Loads both core modules
# User navigates to TUI option 6
# Module detects X: drive, uses X: as target
```

### Scenario 2: FullOS Environment (In-Place Repair Check)
```powershell
# User runs MiracleBoot GUI in Windows
# Clicks "Repair-Install Readiness" tab
# Runs readiness check on C: drive
# Verifies eligibility before launching setup.exe
```

### Scenario 3: Automated Script Mode
```powershell
# Scripts can call directly
. .\EnsureRepairInstallReady.ps1
$result = Invoke-RepairInstallReadinessCheck -TargetDrive "C" -AutoRepair $true

if ($result.FinalRecommendation -eq "READY_FOR_REPAIR_INSTALL") {
    # Safe to proceed with setup.exe
}
```

## Error Handling & Recovery

### Registry Errors
```powershell
# If registry key not found
→ Logs warning but continues
→ Marks as "eligible with warnings"
→ Suggests manual verification
```

### DISM/CBS Failures
```powershell
# If dism /resetbase fails
→ Exits gracefully
→ Logs specific error code
→ Suggests alternative fixes
→ Returns "NOT_READY" status
```

### Privilege Issues
```powershell
# If running without admin
→ Immediate error message
→ Exit code 1
→ GUI shows error dialog
→ TUI shows error and returns to menu
```

## Troubleshooting

### Symptom: "EnsureRepairInstallReady module not loaded"
**Cause:** File not found or syntax error
**Solution:** 
1. Verify EnsureRepairInstallReady.ps1 exists in same directory
2. Check for PowerShell syntax errors: `Test-Path .\EnsureRepairInstallReady.ps1`
3. Run syntax check: Invoke-Pester or manual validation

### Symptom: Eligibility check shows "NOT_READY" after repairs
**Cause:** Critical blocker remains
**Solution:**
1. Export report and review blockers
2. Manually run suggested commands
3. Check TechNet documentation for specific errors

### Symptom: Auto-repair hangs or takes too long
**Cause:** dism /resetbase on large component stores (can take 15+ minutes)
**Solution:**
1. Patient wait (expected behavior)
2. Monitor disk activity
3. Consider running in automated mode overnight for large systems

| Setup Eligibility Check | 2-3 sec | Registry reads only |
| CBS Cleanup | 5-30 min | dism /resetbase is slow |
| WinRE Metadata Repair | 1-2 sec | Quick registry updates |
| Setup.exe Pre-validation | 3-5 sec | Disk/network checks |
| **Total** | **10-40 min** | Depends on CBS size |

### System Requirements
- **Memory:** 200MB
- **Disk:** 100MB free (for temp operations)
- **Network:** Optional (only for metadata download)
- **CPU:** Single-threaded, minimal usage

## Conclusion

The Repair-Install Readiness Engine transforms MiracleBoot from an excellent boot repair tool into a comprehensive **Windows Resurrection Platform** capable of reliably taking systems from "unbootable" → "eligible for in-place upgrade repair."

This critical final layer enables users to avoid the nuclear option (clean install) while preserving their applications and data through Windows' native repair mechanisms.
