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: vc_facility.rb
    path of file: ./repos/vets-api/app/models/facilities
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'facilities/metadata/client'

module Facilities
  class VCFacility < BaseFacility
    class << self
      def pull_source_data
        metadata = Facilities::Metadata::Client.new.get_metadata(arcgis_type)
        max_record_count = metadata
    
      def attribute_map
        {
          'unique_id' => 'stationno',
          'name' => 'stationname',
          'classification' => 'vet_center',
          'phone' => { 'main' => 'sta_phone' },
          'physical' => { 'address_1' => 'address2', 'address_2' => 'address3',
                          'address_3' => '', 'city' => 'city', 'state' => 'st',
                          'zip' => 'zip' },
          'hours' => BaseFacility::HOURS_STANDARD_MAP.each_with_object({}) { |(k, v), h| h[k.downcase] = v.downcase },
          'mapped_fields' => %w[stationno stationname lat lon address2 address3 city st zip sta_phone
