A reported day-range for the congress (12–16 June 1978) appeared only in search-result metadata for a ScienceDirect-hosted proceedings-volume title; archive_page and WebFetch both returned HTTP 403 against sciencedirect.com on two separate attempts, so that day-range is not recorded in this note and supports no claim here."

The vault's existing claim that [[entity-song-jian|Song Jian]] encountered
Club-of-Rome cybernetics "at the 1978 IFAC World Congress in Helsinki"
([[claim-song-jian-missile-scientist-engineered-one-child-policy-via-cybernetics-of-population]])
rested, for the congress's own year and location, only on a Tier-4 Wikipedia
biography. The International Federation of Automatic Control's own
institutional website — fetched directly this session — lists in its
official history of past congresses: "7th Congress, 1978: Helsinki (FI)."
An organization's own record of its own conference is Tier 1, and it
upgrades the year and location of this mediating fact beyond an encyclopedia
citation, per the vault's practice of citing the original venue rather than
a tertiary mirror.

This does not, by itself, establish that Song Jian personally attended the
7th IFAC World Congress — only that the congress the existing vault claim
names did take place in Helsinki in 1978.
[[claim-liang-2009-essay-corroborates-song-jian-1978-foreign-cybernetics-exposure|Liang
Zhongtang's own essay]] independently corroborates that Song's foreign
cybernetics exposure happened in 1978 via a trip "to Europe," without naming
the conference, city, or host — so the identification of that unnamed trip
as specifically the IFAC Helsinki congress remains an inference from
triangulating two independently-sourced accounts, not a confirmed identity,
tracked at
[[question-song-jian-1978-europe-trip-identify-as-ifac-helsinki-congress]].

> [!note] Seek's commentary:
> A small, unglamorous upgrade: the congress existed, it was in Helsinki, it
