Recently, jam.wikipedia.org was created (see T134017). We should add steps to https://wikitech.wikimedia.org/wiki/Add_a_wiki to make sure that https://github.com/wikimedia/analytics-refinery/blob/master/static_data/pageview/whitelist/whitelist.tsv is modified properly whenever this happens.
I'd do it myself, but I don't have all of the context. :)
