# Name Capitalization Conflict
# Detects methods and fields with same name differing only by case

name: Methods and Field Names Should Not Differ Only By Capitalization

message: "'{{NAME}}' differs only by capitalization from existing field/method"

description: |
  Names differing only by case (value vs Value) are confusing
  and violate Java naming conventions. Use distinct names.

  ✅ FIX: Use more descriptive distinct names

  ```java
  private int count;           // field
  public int getCount() { }    // method - distinct
  ```
