Solutions

1. Emit one MockPassAll per package
2. Ensure the single argument is a quoted package-name string

Example fix

// before
MockPassAll("com.a", "com.b")
// after
MockPassAll("com.a")
MockPassAll("com.b")

if (mockPassAllArgs != 1) throw new IllegalArgumentException("MockPassAll takes exactly 1 package arg");

catch (SemanticCheckFailure e) { if (e.getMessage().contains("MockPassAll")) fixArity(); else throw e; }

When it happens

Trigger: `MockPassAll()` with no argument, or `MockPassAll("com.a", "com.b")` with multiple packages.

Common situations: Attempting to pass multiple packages in one call instead of repeated MockPassAll calls, or omitting the argument in templated test setups.
