VividMash is identical to a Mash, with a few exceptions:

Mash uses convert_value to mashify values on input. We override it here to convert hash or array values to VividMash or AttrArray for consistency and to ensure that the added parts of the attribute tree will have the correct cache invalidation behavior.

# File lib/chef/node/attribute_collections.rb, line 167
def convert_value(value)
  case value
  when VividMash, AttrArray
    value
  when Hash
    VividMash.new(value, __root__, __node__, __precedence__)
  when Array
    AttrArray.new(value, __root__, __node__, __precedence__)
  else
    value
  end
