You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: runner.rb
    path of file: ./repos/runbook/lib/runbook
    
    the code of the file until where you have to start completion: module Runbook
  class Runner
    attr_reader :book

    def initialize(book)
      @book = book
    end

    def run(
      run: :ssh_kit,
    
    def run(
      run: :ssh_kit,
      noop: false,
      auto: false,
      paranoid: true,
      keep_panes: false,
      start_at: "0"
    )
      run = "Runbook::Runs::#{run.to_s.camelize}".constantize
      toolbox = Runbook::Toolbox.new
      metadata = Util::StickyHash.new.merge({
        noop: noop,
        auto: auto,
        paranoid: Util::Glue.new(paranoid),
        start_at: Util::Glue.new(start_at || "0"),
        toolbox: Util::Glue.new(toolbox),
        keep_panes: keep_panes,
        book_title: book.title,
      }).
      merge(Runbook::Entities::Book.initial_run_metadata).
      merge(additional_metadata)

      stored_pose = _stored_position(metadata)
      if metadata[:start_at] == "0" && stored_pose
        if _resume_previous_pose?(metadata, stored_pose)
          metadata[:start_at] = stored_pose
        end
