Greenhalgh's 2003 essay — already on file in the vault under a different note — is the connective tissue bridging the Liang 1979-proposal/1985-Yicheng-pilot seed note and the Whyte-Wang-Cai three-stage-timeline seed note

A bridge-seed check tested a cosine-0.88, previously unlinked pairing between claim-liang-zhongtang-1979-two-child-proposal-and-1985-yicheng-pilot and claim-whyte-wang-cai-and-greenhalgh-2003-converge-on-same-three-stage-timeline. The bridge is real, and runs through a note the vault already had on file — claim-greenhalgh-2003-pdr-article-independently-names-liang-zhongtang — that had not previously been wikilinked to either seed note despite citing the exact subject of one and sitting inside one of the two texts compared by the other.

Greenhalgh's 2003 Population and Development Review article — one of the two texts Whyte, Wang & Cai's three-stage-timeline claim compares against her own writing — states that "Liang Zhongtang of the Shanxi Provincial Academy of Social Sciences openly criticized it as potentially coercive and out of touch with rural reality," citing his own essay as "Liang 1985 [1979]" (p. 186). Earlier in the same article she describes scholars who "called for a two-child-plus-long-spacing policy (Liang 1985 [1979])" — the same 1979 counter-proposal that is the subject of the Yicheng-pilot seed note. The existing claim-note already established this citation in isolation, for a different purpose (dating it two years before a 2005 Greenhalgh article making the same point); this check's contribution is identifying that the note sits, unlinked, directly inside the overlap of the two seed notes' subject matter.

This is a new instance of the cluster's recurring "shared landlord" shape (observation-liang-2009-and-greenhalgh-2003-are-symmetric-shared-landlord) — but where that case was two documents independently holding the same pair of facts, this one is a single existing vault note that was simply never pointed at either side of a pairing it already satisfied. Greenhalgh's text is the landlord on the Liang-facing side of this bridge; see the companion note on Whyte-Wang-Cai's own, messier engagement with the pairing's other half, claim-whyte-wang-cai-cite-yan-wei-li-zhang-not-liang-for-yicheng-pilot.
