+/// Guards Iter 23.1: `examples/ordering_match.ail.json` pattern-matches
+/// on the prelude `Ordering` ctor `LT` without an explicit prelude import.
+/// End-to-end: typecheck → codegen → link → run → stdout exactly `"1\n"`.
+/// Property: the implicit prelude import wired by `build_check_env` /
+/// `check_in_workspace` (Iter 23.1 Task 3) propagates through codegen so
+/// the bare ctor name `LT` resolves cross-module without an explicit
+/// `imports: ["prelude"]` entry in the source module.
