   - Top 3-5 high-impact refactoring opportunities
   - Estimated maintainability improvement

2. **For each significant duplication group found:**
   - Type (I: exact, II: structural, III: near-miss, IV: functional)
   - Number of instances and file locations
   - Impact level (High/Medium/Low)
   - Representative code example showing the duplication
   - Recommended refactoring technique(s)...

Analyze the provided code path(s) for duplication using semantic analysis. Generate a detailed deduplication report with:

Executive Summary
- Total duplication statistics (lines, percentage)
- Top 3-5 high-impact refactoring opportunities
- Estimated maintainability improvement
For each significant duplication group found:
- Type (I: exact, II: structural, III: near-miss, IV: functional)
- Number of instances and file locations
- Impact level (High/Medium/Low)
- Representative code example showing the duplication
- Recommended refactoring technique(s)
- Before/after code examples
- Any testing or risk considerations
Consolidation Opportunities
- Extract Methods/Functions for reusable logic
- Extract Constants for repeated values
- Pull Up Methods to parent classes/modules
- Design patterns (Factory, Strategy, Template Method, etc.)
- Utility modules or shared helpers
When NOT to refactor
- Note any coincidental similarity that shouldn't be consolidated
- Identify performance-critical sections where duplication is acceptable
- Flag areas with different change rates that will likely diverge

Focus on semantic duplication that impacts code maintainability. Ignore trivial or coincidental similarities. Prioritize refactorings by impact and feasibility.
