Code

// codemod:skip — negative test: keeps the removed `println` call to exercise removal.
// PIN: `std/io:println` is DELETED (subsumed by print.ln / print). Calling it now
// fails loudly as KORU040 "unknown event" at compiler coordination. GREEN = removed.
~import std/io

const msg: []const u8 = "println is gone";

~std/io:println(text: msg)
