# PT011 IF | ELSE

### NXD Sample:

```nxd
MODULE TEST

FUNC MAIN()
    LET VALID SET false

    IF VALID:
        PRINTLN("PASS")
    ELSE:
        PRINTLN("FAIL")
```
### Result:

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

Expected Output:

### Actual Output:

```nim
# test


proc main() =
  var valid = false
if valid:
    println("PASS")
else:
    println("FAIL")
```

### Notes:
Verified boolean literal parsing for false.
Verified ELSE parsing.
Verified else_branch AST generation.
Verified else_branch IR generation.
Verified JSON serialization of both branches.
Verified Rust deserialization of IRIf with populated else_branch.
Verified backend dispatch correctly invokes emit_if().
Verified Nim backend emits both:
if
else
Verified the entire control-flow structure survives the pipeline:

The presence of both the if and else branches in the generated output confirms that control-flow lowering, transport, and reconstruction are functioning correctly. The defect remains limited to procedure-scoped indentation.

is strong evidence that else_branch survived every compiler phase successfully. In other words, ST010 expanded the control-flow proof started by ST009. The same emitter defect persists, but no new control-flow defects were discovered. That makes ST011 a natural Soft Pass rather than a failure.
