+  Shared name-resolution helpers for the `ix` CLI commands.
+
+  Turning a user-supplied dotted name (`Nat.add_comm`, `_private.M.0.foo`)
+  into either a `Lean.Name` or a content `Address` is needed by several
+  commands (`addr-of`, `check`, …) and by benchmark drivers. These helpers
+  live here — depending only on `Address`/`Environment`/`Ixon` — so callers
+  don't have to pull in the Aiur typecheck machinery just to resolve a name.
