# PT123 Intentional Failure

### NXD Sample:

```nxd
MODULE TEST

FUNC MAIN()
    CONST NAME SET "gabriel"
    LET AGE SET 42
    LET SCORE SET 99.5
    LET ACTIVE SET TRUE

    PRINTLN(NAME)
    PRINTLN(AGE)
    PRINTLN(SCORE)
    PRINTLN(ACTIVE)
```

### Result:

FAIL

### Expected Output:

FAIL -

### Expected Rejection Stage:

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

### Actual Output:

### Notes:

intentional semantics failure. The lexer and parser accepted `TRUE` as an identifier rather than recognizing it as a Boolean literal. AST construction, IR lowering, and JSON generation completed successfully.
The Rust semantic analyzer attempted to resolve `TRUE` as a declared symbol and rejected the program with:
`UndefinedSymbol { name: "TRUE" }` All NXD boolean values are lowercase.
