```

## 🐛 **Critical Bug Fixed**

### **Issue Resolved**
**Problem**: Auto-discovery was incorrectly detecting `aitrackdown` adapter instead of the intended adapter (Linear, GitHub, JIRA) when clear adapter-specific environment variables were present.

**Example of the bug:**
```bash
# User's .env file:
LINEAR_API_KEY=lin_api_YOUR_LINEAR_API_KEY_HERE
LINEAR_TEAM_ID=02d15669-7351-4451-9719-807576c16049
LINEAR_TEAM_KEY=BTA

# MCP Ticketer incorrectly detected:
✓ Detected aitrackdown adapter from environment files  # ❌ WRONG!
```

**Impact**: Tickets were being created in the internal aitrackdown system instead of the intended external system.

### **Fix Implemented**
- **Enhanced detection logic**: Now checks for presence of other adapter variables before detecting aitrackdown
- **Context-aware confidence**: Lower confidence when other adapter configurations are present
- **Explicit override support**: Respects `MCP_TICKETER_ADAPTER` environment variable
- **Improved CLI integration**: Uses enhanced `.env` configuration loader as primary detection method

### **Result After Fix**
```bash
# Same .env file now correctly detects:
✓ Detected linear adapter from environment files  # ✅ CORRECT!
Configuration found in: .env files
Confidence: 100%
```

## 📋 **Technical Changes**

### **Files Modified**
1. **`src/mcp_ticketer/__version__.py`**: Version bumped to 0.3.1
2. **`src/mcp_ticketer/core/env_discovery.py`**: Enhanced `_detect_aitrackdown()` method
3. **`src/mcp_ticketer/cli/main.py`**: Improved CLI auto-discovery flow

### **Key Improvements**
- ✅ **Smart detection**: Considers presence of other adapter variables
- ✅ **Explicit override**: Respects user's explicit adapter choices
- ✅ **Context-aware confidence**: Appropriate confidence scoring
- ✅ **Clear priority rules**: Well-defined detection precedence
- ✅ **Backward compatibility**: All existing configurations continue to work

## 🚀 **Installation and Upgrade**

### **For New Installations**
```bash
# Install latest version with bug fix
pip install mcp-ticketer==0.3.1

# Test auto-discovery
mcp-ticketer init
```

### **For Existing Users**
```bash
# Upgrade to patched version
pip install --upgrade mcp-ticketer

# Verify upgrade
python3 -c "import mcp_ticketer; print(f'Version: {mcp_ticketer.__version__}')"
# Should show: Version: 0.3.1

# Test auto-discovery (should now work correctly)
mcp-ticketer init
```

### **No Configuration Changes Required**
- ✅ **Seamless upgrade**: No configuration file changes needed
- ✅ **Automatic fix**: Bug fix applies immediately upon upgrade
- ✅ **Backward compatible**: All existing setups continue to work
- ✅ **No data loss**: No impact on existing tickets or configurations

## 🧪 **Validation Results**

### **Test Scenarios**
1. **Linear Detection**: ✅ Correctly detects Linear when `LINEAR_*` variables present
2. **GitHub Detection**: ✅ Correctly detects GitHub when `GITHUB_*` variables present
3. **JIRA Detection**: ✅ Correctly detects JIRA when `JIRA_*` variables present
4. **Mixed Scenarios**: ✅ Handles projects with legacy directories correctly
5. **Explicit Overrides**: ✅ Respects `MCP_TICKETER_ADAPTER` setting
6. **Backward Compatibility**: ✅ Existing configurations continue to work

### **User Scenario Validation**
```bash
# Test case: User's exact scenario
# .env file contents:
LINEAR_API_KEY=lin_api_YOUR_LINEAR_API_KEY_HERE
LINEAR_TEAM_ID=02d15669-7351-4451-9719-807576c16049
LINEAR_TEAM_KEY=BTA

# Before v0.3.1 (Broken):
✓ Detected aitrackdown adapter from environment files  # ❌ WRONG!

# After v0.3.1 (Fixed):
✓ Detected linear adapter from environment files  # ✅ CORRECT!
```
