Passing This code compiles and runs correctly.
Code
// A kebab branch name survives a module boundary.
//
// `| parse-error` is a legal Koru name and an illegal Zig identifier. It has
// exactly one correct Zig spelling — the MANGLE, `parse_error` — and never the
// escape, `@"parse-error"`. Both are legal Zig, so a union declaring the field
// one way and a switch arm matching it the other each compile alone and
// disagree only where they meet.
//
// Here the union is emitted for `app/lib` and the switch arm for this consumer,
// by different code paths, which is the cheapest place that disagreement can
// show.
//
// ⚠️ THIS TEST DOES NOT HOLD THE DEFECT IT WAS WRITTEN FOR. It was written to
// pin the kebab mismatch found in orisha (six kebab branches of
// `std/runtime:run`, switched on from inside a router-transform body), and it
// passes with OR without the emitter fix — verified by reverting the fix,
// rebuilding, and re-running. Three shapes were tried: this one, the same
// nested under a subflow arm, and the same as an event implementation body.
// None distinguish. Whatever reaches the escaped spelling lives on the
// transform-generated path, which nothing here exercises. Do not read a green
// here as cover for that.

// does not. `std/runtime:run` declares six of these; this is the shape.
