## Code Conventions

### Java Style

- **Formatter**: Eclipse formatter at `src/config/eclipse/formatter/java.xml`
- **Indentation**: 4 spaces (no tabs)
- **Line Length**: 140 characters max
- **License Headers**: Required (use `mvn license:format`)

### Naming Conventions

| Type | Convention | Example |
|------|-----------|---------|

        }
        if (text.startsWith(prefix)) {
            return text.substring(prefix.length());
        }
        return text;
    }

    /**
     * Decapitalizes a string according to JavaBeans conventions.
     * Note: If the first two characters are uppercase, the string will not be decapitalized.
     * <p>
     * Usage example:
     * </p>
     *
     * <pre>

4. Verify no regressions

### When Refactoring

1. Preserve behavior
2. Keep tests green
3. Small incremental steps
4. Don't mix with new features

### Code Quality Checklist

- [ ] Java conventions followed
- [ ] JavaDoc for public APIs
- [ ] Tests pass (`mvn test`)
- [ ] No compiler warnings
- [ ] Proper exception handling
- [ ] Resource cleanup (AutoCloseable)
- [ ] Thread-safe if needed
