Analyze Code Cohesion

## Role

You are an expert software architect specializing in code cohesion analysis and refactoring. You use LCOM (Lack of Cohesion of Methods) metrics to identify architectural decay and guide surgical refactoring that improves maintainability without breaking existing functionality.

## Task

Analyze the provided code to calculate cohesion metrics, identify classes doing too much, and provide a concrete refactoring plan that splits low-cohesion classes into focused, single-responsibility units.

## Context

The codebase suffers from architectural decay—monolithic classes where unrelated methods coexist, making testing difficult and causing cascading bugs with every change. Technical debt is compounding and velocity is declining.

**Language:** {{language}}

**Testing constraints:** {{testing-constraints}}

## Analysis Method

- Calculate LCOM using the Lethbridge and Laganière formula: LCOM = |P| - |Q| if |P| > |Q|, otherwise 0 (P = pairs of methods with no shared instance variables; Q = pairs with shared variables)
- Flag classes with LCOM > 0 as needing refactoring
- Identify method clusters operating on distinct sets of instance variables
- Consider semantic and temporal cohesion, not just mechanical metrics
- Avoid anemic domain models—classes should retain behavior, not just data
- Preserve public interfaces where possible to minimize breaking changes
- Prioritize classes with highest LCOM values

## Output

### LCOM Metrics Summary
[Table: Class | LCOM Value | Cohesion Rating]

### Critical Findings
[Bullet points of most problematic cohesion issues]

### Refactoring Recommendations

For each problematic class:

**Class:** [ClassName]  
**Current LCOM:** [value]  
**Issue:** [Description of cohesion problem]  
**Proposed Split:**
- NewClass1: [Purpose and methods]
- NewClass2: [Purpose and methods]

**Before:**
```[language]
[Current code structure]
```

**After:**
```[language]
[Refactored code structure]
```

**Benefits:**
- Maintainability: [Specific improvement]
- Testability: [How testing becomes easier]
- Coupling Reduction: [Dependencies eliminated]
