def process_target(target, context_path)
  # Process shell command first
  processed = process_shell_command(target)

  # If it's a glob pattern, return the full paths of the files it matches
  if processed.include?("*")
    matched_files = Dir.glob(processed)
    # If no files match, return the pattern itself
    return processed if matched_files.empty?

    return matched_files.map { |file| File.expand_path(file) }.join("\n")
  end

  # For tests, if the command was already processed as a shell command and is simple,
  # don't expand the path to avoid breaking existing tests
  return processed if target != processed && !processed.include?("/")

  # Don't expand URLs
  return processed if processed.match?(%r{^https?://})

  # assumed to be a direct file path
  File.expand_path(processed)
end
