Not yet independently re-checked by the verifier bee. | CORRECTED 2026-11-04 (scheduled cross-model audit, auditor claude-fable-5): source_quote carried ' (p. 269)' inside the quotation marks — a page citation baked into text presented as verbatim, the cause of the 2026-11-04 quote_sweep FAIL; the page cite was moved out of the quote (now in source_title). source_quote_2's inner quotation marks were also restored to the source's own double quotes (escaped per the 2026-10-01 quote-shape ruling) instead of swapped-in single quotes. Both passages re-verified verbatim this audit against a fresh extract_pdf of source_url (sha256 identical 1fa56f50…, tls verified; capture lines 827–830 and 808–810, running headers confirming pp. 269 and 268).

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-li-xiuzhen-1980-speech-frames-one-child-recommendation-as-still-being-tested]].
The bridge is real: both seed notes describe artifacts of one identical
real-world event, not merely a thematic echo.

[[entity-susan-greenhalgh|Greenhalgh]]'s 2005 *China Quarterly* article
states that "Song and Li Guangyuan presented the group's findings for the
first time" at "the Second National Symposium on Population Theory, held
in Chengdu from 7 to 13 December" (p. 269) — the same event the Liang seed
note (via a 2016 Sixth Tone profile) calls "the Second National Demography
Symposium in Chengdu, Sichuan province," where
[[entity-liang-zhongtang|Liang Zhongtang]]'s two-child proposal "fell on
deaf ears." The identification is clinched by Greenhalgh's own footnote 51
(p. 268), which cites "Li Xiuzhen, 'Dangqian jihua shengyu gongzuo de
xingshi he renwu' ('The situation and duties of birth planning work today
(13 December 1979)'), *Renkou yanjiu*, No. 1 (1980), p. 5" — the identical
title, romanization, journal, and issue the vault's existing
[[entity-li-xiuzhen|Li Xiuzhen]] claim-note already treats as its Tier-1
primary source, read directly by the vault on 2026-09-10. Greenhalgh is
citing the same document the vault independently read in full, and dates
it to the same closing day (13 December 1979) that document's own
conference report separately records.

Two seed notes an embedding model flagged only by vocabulary overlap turn
out to share one calendar event, corroborated from two independent reading
sessions and two different citation chains into the same primary document.
