## Version Mapping System

### How It Works

**Semantic Version → 3-Digit Ordinal Mapping:**

```
Version Format: MAJOR.MINOR.PATCH
Ordinal Format: nnn (where n = 0-9 per position)

Formula: (Major × 100) + (Minor × 10) + Patch

Examples:
1.0.0 → (1×100) + (0×10) + 0 = 100
1.0.1 → (1×100) + (0×10) + 1 = 101
1.2.3 → (1×100) + (2×10) + 3 = 123
2.5.7 → (2×100) + (5×10) + 7 = 257
9.9.9 → (9×100) + (9×10) + 9 = 999
```

### Script Naming Convention

```
SQM_Update_nnn.ps1

Where:
- SQM = Sequential mojoPortal (naming prefix)
- Update = Operation type
- nnn = 3-digit ordinal matching version

Examples:
SQM_Update_100.ps1 → Version 1.0.0
SQM_Update_101.ps1 → Version 1.0.1
SQM_Update_110.ps1 → Version 1.1.0
SQM_Update_153.ps1 → Version 1.5.3
SQM_Update_200.ps1 → Version 2.0.0
```

### Why This System

✅ **Logical sequencing** — 100, 101, 102... appears in order  
✅ **No gaps** — Can't have 0.0.10 (single digit per position)  
✅ **Easy calculation** — Convert version to ordinal in seconds  
✅ **Predictable** — Always know next version number  
✅ **Scalable** — Supports versions up to 9.9.9  
✅ **File system friendly** — Works perfectly in directory listings  
✅ **Automatable** — Scripts can calculate versions programmatically

## Workflow: From Current (1.0.0) to Next (1.0.1)

### Step 1: Identify Next Version
```
Current: 1.0.0 (ordinal 100)
Next: 1.0.1 (ordinal 101) — This is a patch fix
Reason: Bug fix, no new features
```

### Step 2: Create Update Script
```powershell
# Copy template
Copy-Item ".\Updates\SQM_Update_100.ps1" ".\Updates\SQM_Update_101.ps1"

# Edit SQM_Update_101.ps1:
# $CurrentVersion = "1.0.1"
# $UpdateName = "SQM_Update_101"
```

### Step 3: Add Specific Changes
```powershell
# In Apply-UpdateChanges function:
Write-Substep "Applying migration engine bug fix"
Copy-Item ".\mojoPortal.Data.SQLite\LegacyDataMigrationEngine.cs" `
    -Destination "$SourcePath\mojoPortal.Data.SQLite\" -Force
```

### Step 4: Create Changelog
```markdown
# CHANGELOG_101.md

## Version 1.0.1 — Bug Fixes

### Issues Fixed
- Fixed module type mapping in migration engine
- Resolved null reference in analysis
- Corrected permission inheritance

### Files Modified
- mojoPortal.Data.SQLite/LegacyDataMigrationEngine.cs
- mojoPortal.Data.SQLite/LegacyMigrationHelper.cs
```

### Step 5: Test and Apply
```powershell
# Dry run first
.\Updates\SQM_Update_101.ps1 -DryRun

# Then apply
.\Updates\SQM_Update_101.ps1
```

### Step 6: Verify Success
```powershell
# Check version was updated
Get-Content "VERSION.md" | Select-String "Version"
# Output: **Version:** 1.0.1 ✓

# Verify backup was created
Get-ChildItem ".\Backups" | Sort-Object Name -Descending | Select-Object -First 1
# Output: 2024-01-20_v101 ✓

# Check history was logged
Get-Content "VERSION_HISTORY.md" | head -10
```
