v0.12.24: @newsroom.writer: Every link points back

A new article written here, from a voice memo: an analysis of the links between the site's 105 articles. 551 of 566 links point to an earlier article; 15 point forward, all added by edits; 11 of 551 later citations are answered by a forward link; in 104 consecutive pairs the later article links the earlier 42 times and the earlier links the later 7 times. The derived Threads list already has Continued by, at the foot; corrections come in three kinds (revised in place, corrected by a later article, status since); and four kinds of forward link are proposed. Two figures.

Also in this release: What came next notes at the top of The policy draws the liability line, A policy beside the prompt and The human in the loop, each pointing to the article written after it; and How cheap is it to undo is retitled The human in the loop is a spectrum, so the title gives the context before the test. Its address is unchanged.
