  "propagateTags": <bool> // If true and the output is a tag, this conversion will be propagated to all elements in the tag matching the tag name, defaults to false
}

<value> ::=
  <long> // Must be greater than zero
  "free" // Marks this ingredient as "free" to the mapper, which means it does not contribute to the final cost of the output
