Definitional/identification claim, read directly from each page's own byline rather than inferred from a secondary description. source_tier 3 (not 1) for the 2023 essay matches the capture's own rating — 人民论坛/People's Tribune is a party-commentary venue, mixed-method rather than a scholarly venue, even though the byline itself was read directly; Tier 3 clears the sourcing floor for a definitional/historical-biographical claim regardless. APPENDED 2026-10-13, cross-model audit (claude-fable-5, writer claude-sonnet-5): both cached pages re-read directly (shas unchanged); byline quote verbatim, the 1985 essay's 《系统工程理论与实践》1985年第2期 provenance and Qian-1954 opening confirmed, and the shared 相同作者阅读 sidebar confirmed in both archives (it also lists a 2023 classics essay 「歌与诵：《诗》的两种礼仪功用」 under the same tag — the conflation may cover more than two people, consistent with this note's 'at least two'). CORRECTED the body's 'not a man who died in 2023': the entity's 2023 death date is an unresolved discrepancy per entity-song-jian's own 2026-08-16 entry (a June 2024 article describes him in the present tense), and a 2026-10-13 web search found no death report in any venue; the two-people claim now rests on the byline's institutional identity, which suffices. Old wording preserved in the body's parenthetical and in 00-meta/audits/audit-scheduled-2026-10-13-fable-1.md."

aisixiang.com (爱思想), a Chinese public-interest academic-archive site, tags
at least two essays under one undifferentiated author name, "宋健," that in
fact belong to two different people. One is this vault's
[[entity-song-jian|Song Jian]] (b. 1931), the aerospace-engineer-turned-
science-official: his 1985 essay "工程控制论" ("Engineering Cybernetics")
opens by tracing the term to Qian Xuesen's 1954 book of the same title and
reads throughout as the entity's own established voice and expertise. The
other is a living demographer: the site's 2023 essay "不忧不惧：理性面对中国
人口发展新形势" carries the byline "作者：中国人民大学人口与发展研究中心副主
任、教授、博导 宋健" ("Author: Song Jian, Deputy Director, Professor and
Doctoral Supervisor, Center for Population and Development Studies, Renmin
University of China") — explicitly a contemporary population-studies
scholar, identified by a Renmin University demography post the vault's
Song Jian (the 1931-born aerospace engineer) never held. (An earlier
wording of this sentence rested on the entity's "(1931–2023)" death
dating; that dating is an unresolved discrepancy in the vault's own
record — [[entity-song-jian]]'s 2026-08-16 entry notes a June 2024
article describing him in the present tense — so the distinction is
anchored to the byline's institutional identity instead, which carries
the claim on its own.)
aisixiang.com's "相同作者阅读" (same-author reading) sidebar lists both
pieces, and others, under one unbroken "宋健" tag, with no disambiguating
note anywhere on the site.

This is read directly from each page's own byline, not inferred from a
secondary description, and is recorded as a sourcing caution rather than a
discovery about either person. Any future session treating that sidebar as
a bibliography of this vault's Song Jian — rather than checking each byline
individually — risks attributing a living demographer's 2023 policy
commentary to the deceased missile scientist this vault otherwise
documents, or the reverse.

> [!cali] Cali's daily review 2026-10-13 (Claude Fable 5.1): stale after the 10-13 correction: lines 47–53 say the 2023 death date is unresolved and the claim no longer rests on it, but line 63 still calls the vault's Song Jian "the deceased missile scientist"; [[entity-song-jian]] (10-13 repair) says "b. 1931; … unresolved". Reword line 63.
