A second, independent peer-reviewed paper corroborates the Rothschild 1971 'customer-contractor' quote and pins it to Section II, Paragraph 6

The load-bearing quote behind the vault's existing note on Rothschild's customer-contractor principle had reached the vault only through a PDF mirror on a conspiracy-oriented host. Fetched directly from Miles Parker's paper at its own canonical venue — now branded Humanities and Social Sciences Communications, DOI and article number unchanged — the text reads: "II.6—'the principle that applied R. & D., that is R. & D. with a practical application as its objective, must be done on a customer-contractor basis. The customer says what he wants; the contractor does it (if he can); and the customer pays'." This is an exact match to the wording already recorded in the vault.

A second, separately peer-reviewed paper independently quotes the same passage. Neil Calver and Miles Parker, "The logic of scientific unity? Medawar, the Royal Society and the Rothschild controversy 1971–72" (Notes and Records of the Royal Society, 2015), quotes: "that applied R. & D., that is R. & D. with a practical application as its objective, must be done on a customer–contractor basis. The customer says what he wants; the contractor does it (if he can); and the customer pays." (Only a hyphen-vs-en-dash difference from the wording above — typographic, not textual.) The paper's own footnote 37 states: "The quotation that follows is from section II, paragraph 6 of Rothschild's report" — independently pinning both wording and exact location. Miles Parker co-authored this paper too, so it is not a fully independent source by the vault's single-source-concentration standard (same lead author, different venue and discipline framing — history of science vs. personal memoir); it is best read as strong corroboration, not two unrelated witnesses.

Both papers also independently supply full citations for the report's press nicknames — "Lord Rothschild's Cat for All Pigeons" (Nature 234 (5326): 163–164, 1971) and "The Rothschild Bombshell" (New Scientist 52 (772): 6, 1971) — and confirm the 1972-adopted / 1974-implemented timeline. What neither paper substitutes for: the original 1971 HMSO document itself, A Framework for Government Research and Development (Cmnd. 4814), which was not located as digitized text anywhere online during this search — only catalogue records at The National Archives and Wellcome Collection describing physical holdings. The quote's wording and location are therefore confirmed by two independent-venue secondary quotations, not by a direct read of the primary government document.
