# FT109 Intentional Failure

### NXD Sample:

```nxd
MODULE TEST

FUNC MAIN()
    LET VALID SET TRUE

    IF VALID:
        PRINTLN("True")
```

### Result:

FAIL

### Expected Output:

FAIL - Undefined symbol

### Expected Rejection Stage:

[ ] Lexer
[ ] Parser
[ ] AST
[ ] IR
[X] Semantics
[ ] Backend

### Actual Output:

  ],

}
```

### Notes:

intentional Semantics failure. NXD requires lowercase boolean literals.
TRUE is interpreted as an identifier rather than a boolean literal.
String literals are exempt from capitalization rules.
Example:
TRUE -> invalid symbol
"True" -> valid string literal
Compiler Result:
UndefinedSymbol { name: "TRUE" }
