      # cargo's publish output for "already exists on crates.io index"
      # / "already uploaded". Same pattern as standout/dodot/padz/rustloc.
      # Replaces the prior `cargo search VERSION grep` heuristic which
      # broke when re-running an older release (cargo search returns
      # only the LATEST version, so the grep wouldn't match older ones).
