# QA: Comprehensive Output Style Enforcement Verification

## Description
Execute comprehensive testing of the claude-mpm output style enforcement system to verify it always enforces claude-mpm style as default, even when users try to change it.

**Implementation Details**:
- `OutputStyleManager` in `src/claude_mpm/core/output_style_manager.py` provides continuous enforcement
- Detects user changes and automatically restores claude-mpm style
- Integration with interactive session startup in `src/claude_mpm/core/interactive_session.py`

**Test Requirements**:

1. **Startup Enforcement**: Verify claude-mpm style is activated on startup
   - Check settings.json modification on startup
   - Verify activeOutputStyle is set to 'claude-mpm'
   - Confirm startup logging shows enforcement activation

2. **User Change Detection**: Test that changes to activeOutputStyle are detected
   - Manually change activeOutputStyle to 'default' or other values
   - Verify automatic detection and restoration
   - Test various style values (default, minimal, etc.)

3. **Automatic Restoration**: Confirm style is restored to claude-mpm
   - Verify restoration happens within reasonable timeframe
   - Check enforcement counter increments correctly
   - Ensure restoration is logged properly

4. **Logging Clarity**: Check that messages clearly indicate enforcement
   - Startup: "✅ Output style 'claude-mpm' is enforced and active"
   - Change detected: "⚠️ Output style changed from 'claude-mpm' to 'X'. Restoring claude-mpm style..."
   - After restoration: "✅ Output style 'claude-mpm' has been restored (enforcement #N)"

5. **Edge Cases**:
   - Missing settings.json file
   - Corrupted settings.json content
   - File permission issues
   - Older Claude versions (< 1.0.83)
   - Invalid activeOutputStyle values
   - Concurrent modification scenarios

6. **Performance Impact**: Ensure enforcement doesn't impact performance
   - Monitor file system operations frequency
   - Check startup time impact
   - Verify no excessive polling or resource usage

7. **Integration Testing**: Test with actual claude-mpm sessions
   - Run interactive sessions with enforcement active
   - Test during agent delegation workflows
   - Verify no interference with normal operations

**Expected Behavior**:
- Style enforcement should be transparent to users
- claude-mpm style should remain active at all times
- Clear, informative logging without being verbose
- No performance degradation
- Graceful handling of all edge cases

**Deliverables**:
1. Comprehensive test scripts covering all scenarios
2. QA report with pass/fail status for each test category
3. Performance impact assessment
4. Edge case handling verification
5. Integration test results
6. Recommendations for any issues found

**Success Criteria**:
- All tests pass with claude-mpm style consistently enforced
- No performance issues or resource leaks
- Clear logging and user feedback
- Robust error handling for edge cases
- Seamless integration with claude-mpm operations
