source_quote: "The group's leader, Song Jian, got the idea for this project on a delegation visit to Europe in 1978. ... After more than ten years' isolation from the outside world, during a visit to Europe in 1978, I happened to learn about the application of systems analysis theory by European scientists to the study of population problems with a great success. ... I was extremely excited about these documents and determined to try the method of demography. (Song 1986: 2-3) [p. 170] ... At its first meeting in June 1978, the newly revamped Birth Planning Leading Group, the forerunner of the State Birth Planning Commission, recommended that 'it is best to allow only one birth, two are the most, and third births must be strictly controlled.' This recommendation was approved by the Central Committee of the party and by the State Council (Li 1980: 5). [p. 185]"

[[claim-greenhalgh-1976-predates-1978-sequencing-depends-on-contested-song-jian-dating|The
1976-predates-1978 note]]'s entire "1978" dating for
[[entity-song-jian|Song Jian]]'s cybernetics encounter — the dating
[[entity-geert-jan-olsder|Olsder]]'s contested 1975 account threatens to
reverse — traces, via
[[claim-greenhalgh-2003-and-2005-1978-dating-footnotes-cite-identical-song-1986-essay-pages|the
identical citation already on file]], to
[[entity-susan-greenhalgh|Greenhalgh]]'s 2003 *PDR* article, p. 170: "The
group's leader, Song Jian, got the idea for this project on a delegation
visit to Europe in 1978," quoting Song's own words, cited "(Song 1986:
2-3)." Fifteen pages later, at p. 185, the same article states that "at
its first meeting in June 1978, the newly revamped Birth Planning Leading
Group... recommended that 'it is best to allow only one birth, two are the
most, and third births must be strictly controlled,'" approved by the
Central Committee and State Council — the passage
[[claim-greenhalgh-2003-article-independently-corroborates-june-1978-leading-group-meeting|the
June-1978-leading-group note]] draws on.
[[observation-liang-2009-and-greenhalgh-2003-are-symmetric-shared-landlord|A
prior bridge-check]] already placed these same two passages, fifteen pages
apart, in this article; what neither that note nor either target note had
stated directly is that these are the specific citations these two
particular notes each rest on, and that the two notes had never been read
against each other before this session.

Sharing a document is not sharing an argument. The p. 170 dating rests
entirely on Song's own unread 1986 essay — the account Olsder's 1975 story
contests. The p. 185 dating rests on a separate citation, "Li 1980: 5,"
uncontested by anything in the Olsder dispute. Neither citation invokes
the other, in the article's own text or in any vault session's reading of
it. The Olsder challenge that threatens the 1976-predates-1978 note's
sequencing therefore does not touch the June-1978-leading-group note's
corroboration, and that corroboration's independent robustness cannot be
borrowed back to rescue the contested dating — despite both citations
sitting fifteen pages apart in one continuous narrative arc of one
article.
