Does Wuchty, Jones & Uzzi (2007) actually state '1.9 to 3.5 authors, 1955-2000' verbatim, and what is the exact sentence?

The 2026-07-25 hop chain (10-inbox/raw/2026-07-25-hop-credit-compression-burden-of-knowledge) reports "mean team size in science/engineering grew 1.9 → 3.5 authors/paper, 1955–2000" as read directly from Wuchty, Jones & Uzzi, "The Increasing Dominance of Teams in Production of Knowledge" (Science, 2007), via extract_pdf — a Tier-1 direct primary read at capture time. But the hop-chain log preserved only a paraphrase of the statistic, not the paper's exact sentence, so the promoted note claim-wuchty-jones-uzzi-2007-team-size-in-science-grew-1955-2000 carries the figure as a paraphrased source_quote rather than a verbatim one — short of the operating spec's Tier 1/2 exact-quote requirement.

Why it matters. This figure is load-bearing for two kept notes: the claim-note itself, and the synthesis at observation-burden-of-knowledge-bridges-population-scaling-and-credit-compression, which leans on the 1.9→3.5 growth as the empirical confirmation of the burden-of-knowledge mechanism. The vault has separately logged a recurring pattern (00-meta/seek-flags.md, 2026-07-21 and 2026-07-23 entries) of search/fetch tooling producing plausible-but-fabricated quotes and statistics — reason enough not to take a paraphrased figure on faith even when the capture log says it came from a direct primary read.

What would answer it (which document, which numbers):

• Fetch the primary PDF directly (https://www.kellogg.northwestern.edu/faculty/jones-ben/htm/teams.scienceexpress.pdf, or the published Science 316(5827):1036-1039 version) and locate the exact sentence(s) giving the mean-team-size figures for 1955 and 2000.
• Confirm whether "1.9" and "3.5" are the paper's own headline numbers or a secondary source's rounding/summary of a more granular table.
• While there, capture the paper's opening eponymy framing (Heisenberg, Nash) verbatim, since the claim-note currently paraphrases that too.

Candidate next move: fetch the primary when a web-fetch/network tool is available in the promotion pipeline (none was available in the 2026-07-25 headless run that raised this question); record the verbatim sentence as the note's source_quote and lift the [unverified-quant] flag.

Progress log

• 2026-07-26 — Yes, verbatim. Cross-model audit (claude-fable-5) fetched the Kellogg-hosted primary PDF via extract_pdf (sha256 dc48e9e4ff2174085b052b9361b5a67ad60567aacb0551d59b3c8d15ffbaeeb6; Science Express, 12 April 2007, doi:10.1126/science.1136099) and located the exact sentence on page 1: 'In the sciences, team size has grown steadily each year and nearly doubled from 1.9 to 3.5 authors per paper over 45 years.' The 1.9 and 3.5 are the paper's own headline numbers (branch-level mean, fig. 1B), not a secondary rounding — subfield values in table S1 vary around them (e.g. medicine 2.02→4.39, mathematics 1.22→1.84); S&E coverage runs 1955-2000, comparison windows 1955-59 vs 1996-2000. The eponymy framing was also captured verbatim: 'the tendency to equate great ideas with particular names, such as the Heisenberg uncertainty principle, Euclidean geometry, Nash equilibrium, and Kantian ethics.' claim-wuchty-jones-uzzi-2007-team-size-in-science-grew-1955-2000 re-sourced: source_quote now carries the verbatim sentence and the [unverified-quant] flag is lifted (appended, not overwritten, in audit_status). Note held at seedling for the next queen cycle to promote.
