• What genuinely connects the 1976-predates-1978/Olsder-dating claim and the 2003-article/June-1978-leading-group claim: both trace to the same Greenhalgh 2003 article, fifteen pages apart, anchoring opposite ends of its evidentiary strength

• What genuinely connects the Liang-Forrester 'connect only through the Song Jian note' claim and the Greenhalgh 2003/2005 'identical Song 1986 essay pages' claim: the mediating node in the first is built from the same article whose citation apparatus the second interrogates

• In Greenhalgh's 2003 PDR article, both instances of the Dutch-work critique fall entirely outside the pp. 178–187 citation-to-dissent run — one before it opens, one at its tail — bracketing the run rather than sitting inside it

• In Greenhalgh's 2005 China Quarterly article, the Dutch-work critique (pp. 266–267) is not merely adjacent to the consensus-to-dissent arc — it is a fourth constituent beat inside that single continuous run

• The 1976-predates-1978/Olsder note and the June-1978-leading-group note connect through a shared document — Greenhalgh's 2003 article — not a shared argument, and the robust pole's corroboration cannot rescue the fragile pole's contested dating
