• curprev 23:4523:45, 12 January 2019‎ Rainwarrior talk contribs‎ 19,881 bytes −17‎ this article and iNES need to refer to each other, header numbering and field names should use the same convention in both

Not sure if I've listed all the relevant mappers, but I think this gets most or all cases?
• curprev 04:2404:24, 8 August 2018‎ Rainwarrior talk contribs‎ 15,098 bytes −74‎ →‎Overview: the lead already credits KH and links to his original proposal, but he is not really the writer of this living document at this point? (special thanks are also relegated to that original document)
