# PT009 (micro test)

### NXD Sample:

```nxd
MODULE TEST

FUNC MAIN()
    LET VALID SET true

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

### Result:

COMPILER: SOFT PASS *(see notes)
SEMANTICS: PASS

Expected Output:

if valid:
    println("PASS")

```


### Notes:

Verified boolean literal parsing for true.
Verified boolean literal AST generation.
Verified boolean literal IR generation.
Verified boolean serialization into JSON IR.
Verified Rust deserialization of boolean literal nodes.
Verified IF statement parsing.
Verified AST → IR lowering for control flow.
Verified IRIf serialization and deserialization.
Verified IRStatement::If dispatch successfully reaches the Nim control-flow emitter.
Verified Nim backend emits an if construct instead of the previous placeholder (# TODO: emit if statement).
Confirmed end-to-end control-flow transport through:

#### Defect Identified:

The emitted if statement is generated outside the enclosing procedure scope

#### Impact:

Does not indicate a parser failure.
Does not indicate an IR failure.
Does not indicate a JSON or Rust deserialization failure.
Confirms control-flow functionality is present.
Requires indentation correction in the Nim emitter.
Technical Significance

This test represents the first successful validation of NXD control-flow statements through the full compiler pipeline. It confirms that boolean literals and IF statements are correctly recognized, lowered, serialized, reconstructed, and emitted. The remaining issue is limited to backend formatting rather than language feature implementation.
