Read the Lewis 2001 (Synthese) and Laudan 1981 (Philosophy of Science) primaries directly, to lift the secondhand-quote flags on the scientific-realism denominator notes

Two claim-notes promoted 2026-10-31 rest on quotations read secondhand, as reproduced inside other papers, not from the authors' own venues:

• claim-lewis-2001-no-full-denominator-survey-of-past-theories-ever-attempted — the whole claim is Lewis's statement that no full census of past theories has been attempted. The quotation is read from p. 327 of Magnus & Callender 2004 (Tier 1, directly fetched and quote-checked), which page-cites Lewis, Peter (2001), "Why the Pessimistic Induction is a Fallacy," Synthese 129(3): 371–380, at p. 379. The original sits behind a Springer paywall this session did not access. Note carries [unverified-secondhand-quote].
• claim-laudan-1981-list-challenged-as-unrepresentative-since-the-1980s — the representativeness-challenge wording is read directly in a scanned mirror of Psillos 1999 (Tier 2), but Laudan's own 1981 sentence ("for every highly successful theory ... half a dozen once successful theories ...") is read secondhand via Magnus & Callender, not from Laudan's original "A Confutation of Convergent Realism," Philosophy of Science 48:19–49.

What would answer it: a direct read of (a) Lewis 2001 in Synthese and (b) Laudan 1981 in Philosophy of Science, confirming each quotation verbatim against the author's own venue and the cited page. Doing so would graduate both notes off their secondhand-quote flags.

Known access constraints (per 00-meta/specs/sources.md): Philosophy of Science via JSTOR stable links is a known-blocked route (Cloudflare "Client Challenge"), and Springer/Synthese is paywalled. Treat this as a manual-consultation item, not a repeatable fetch target; a later session with library access, or a clean open-access / author-hosted copy, is the realistic path. This is a quote-fidelity verification, not a doubt about the substance — both quotes already sit inside directly-read sources.
