Waddington's own 1968 Nature account of the Villa Serbelloni theoretical-biology symposia he organized never mentions Wiener or cybernetics

C. H. Waddington wrote his own summary, for Nature (vol. 218, pp. 525–527, 1968), of the two IUBS-sponsored theoretical-biology symposia he organized at the Villa Serbelloni (1966–67) — the same symposia secondary biography (Wikipedia) credits as the moment Waddington brought cyberneticists and biologists into the same room. A direct full-text search of the fetched article, read in full, confirms that neither "Wiener" nor "cybernetics" appears anywhere in it. Waddington instead credits von Neumann, Pattee, Bohm, Longuet-Higgins, Michie, and statistical mechanics as the sources of the ideas discussed. Wiener died in 1964, two years before the first symposium, and could not have attended in person even if invited.

Combined with claim-waddington-1957-cybernetics-of-development-chapter-credits-ashby-not-wiener, this means Waddington's contemporary scientific writing about development and theoretical biology (1957, 1968) does not name Wiener even where cybernetics or a cybernetics-adjacent gathering is the explicit subject. The Wiener self-credit found in claim-waddington-1977-whitehead-essay-names-wiener-cybernetics-as-lineage comes from a later, more retrospective and philosophical piece, not from Waddington's own account of the specific event (the Serbelloni symposia) that secondary biography ties the Wiener connection to.
