// A generic value-failable fn `($R, !E)` reached through a RE-EXPORT alias
// keeps its `!` error channel at the call site — the result types as a
// value-failable, so `or` / `try` accept it. Mirrors std.sx's
// `await :: io_mod.await` (+ `IoErr :: io_mod.IoErr`) re-export.
// Regression (issue 0153): the planned call-result type was resolved in the
// CALL-SITE module (where `LE` is a re-export alias → a non-`.error_set`
// TypeId), so `errorChannelOf` saw a plain tuple and `b.get() or {…}` built a
// malformed i1 PHI. The fix pins return-type resolution to the fn's defining
// module, matching `monomorphizeFunction`. Needs BOTH generic + re-export.
