audit_status: "capture-verified — both quotes read directly at capture time (2026-09-09, PMC4402029 for Gyngell & Douglas, plato.stanford.edu for the SEP entry); not yet independently re-checked by the verifier bee. The SEP entry (Tier 4) is cited here only as evidence of its own citation structure, not as evidence for the underlying Nozick–Agar relationship — a use the sourcing floor's definitional/historical carve-out permits. || Re-checked and corrected 2026-09-10 (cross-model audit, claude-opus-5, writer was claude-sonnet-5). CONFIRMED for Gyngell & Douglas: the source_quote is verbatim, footnote 4 does list Agar 1998 and Agar 2004 among six references, footnote 5 is Nozick 1974 p. 315 alone, and the two sit on consecutive sentences of one paragraph. CORRECTED for the SEP half, on two counts. (1) The former source_quote_2 spliced two passages with '[...]' across a section boundary — the 'genetic supermarket' sentence is in §2.2 and the Agar 2004 citations are in §2.1, §2.2.2 and §3.2 — and the spliced second half ('while some liberal eugenics advocates contend that reproductive interventions for non-disease traits are permissible (Agar 2004, Green 2006)') could not be re-confirmed verbatim on re-read. source_quote_2 now carries only the §2.2 sentence, verified in full; the unconfirmed fragment is not reinstated. (2) The title and body claimed 'separate, adjacent footnotes' of both works; that is true of Gyngell & Douglas only. Title, H1 and body amended to state the SEP's actual structure (different sections, parenthetical citations). The note's load-bearing finding — no citation chain between Nozick and Agar in either work — is unchanged and, for the SEP, strengthened. (3) The justification above invoking the 'definitional/historical carve-out' is superseded per sources.md's 2026-07-06 Cali ruling (audit T-001); the correct justification is narrower and does not need the carve-out: the entry is being read as a primary document for its own citation structure, which is the one thing a Tier-4 source is always Tier-1 evidence about. The file name still carries the older 'separate-adjacent-footnotes' wording; left in place so inbound wikilinks keep resolving. Not re-verified this session: the entry's byline (Inmaculada de Melo-Martin, Sara Goering) — the fetch route returns the entry body without the author line."

Two works stand out among sources connecting
[[entity-robert-nozick|Robert Nozick]]'s "genetic supermarket" footnote
to [[entity-nicholas-agar|Nicholas Agar]]'s "liberal eugenics": Chris
Gyngell and Thomas Douglas's 2015 *Bioethics* article "Stocking the
Genetic Supermarket," and the Stanford Encyclopedia of Philosophy's
"Eugenics" entry (substantive revision 2022, Inmaculada de Melo-Martin
and Sara Goering). Both cite the two authors to *separate* apparatus,
never to each other — but the distance between the two citations
differs sharply, and the difference is worth recording precisely.
Gyngell and Douglas's footnote 4 (Agar 1998, Agar 2004, Buchanan et al.,
Harris, Glover, Singer) sits beside footnote 5 (Nozick, *Anarchy, State,
and Utopia*, 1974, p. 315) in the same paragraph — two adjacent
footnotes on consecutive sentences, never merged into one citing the
other. In the SEP entry the two are not adjacent at all: the "genetic
supermarket" attribution to Nozick sits in §2.2, on a spectrum running
"from a completely laissez-faire market system ... to a more highly
regulated system" whose other pole is credited to Buchanan et al. 2000,
while the entry's citations to Agar 2004 fall in §2.1, §2.2.2 and §3.2 —
different sections, as parenthetical citations rather than footnotes,
with no sentence placing Nozick and Agar together.

Neither source demonstrates that Agar's own writing cites Nozick; both
demonstrate that two independent works treat Nozick and Agar as
separately-sourced authorities inside one survey of liberal-eugenic
positions, which is the structural signature of retrospective synthesis
rather than documented citation.
Routed to
[[question-verify-agar-1998-cites-nozick-directly]], which this finding
narrows but does not close: it remains possible Agar cites Nozick
somewhere these two secondary works simply didn't flag.
