# Test Output Style Installer Fix - Comprehensive Verification

## Description
**Context**: The `deploy_output_style` method in `src/claude_mpm/core/output_style_manager.py` was modified to always activate the claude-mpm style regardless of whether it already exists.

**Requirements**: Verify comprehensive testing for output style installer functionality:

**Fix Details**:
1. Always activate claude-mpm style regardless of existing state
2. Replace any user customizations with system version  
3. Always set activeOutputStyle to "claude-mpm" in settings.json

**Test Scenarios Required**:
1. Fresh installation (no existing style)
2. Existing installation (style already exists - should overwrite)
3. activeOutputStyle set to different value (should change to claude-mpm)
4. Missing settings.json (should create)
5. Multiple runs (should be idempotent)
6. Corrupted settings files

**Verification Points**:
- Running installer always sets activeOutputStyle to "claude-mpm"
- claude-mpm.md file always written to ~/.claude/output-styles/
- Existing user style replaced with system version
- settings.json properly updated
- Works with fresh, existing, corrupted scenarios

**Deliverables**:
1. Comprehensive test suite covering all scenarios
2. Test execution results and verification
3. QA sign-off on output style installer functionality
4. Documentation of any issues found
