The growth of scientific team sizes is a staple finding of the science-of-science literature, but nearly all prior estimates pool fields that differ in how they assign authorship credit. We exploit authorship-ordering convention as a natural stratification: in alphabetical-authorship fields (economics, finance, mathematics), author position carries no career weight and so offers no incentive for gift or honorary authorship, while in contribution-ordered fields (biomedicine, clinical science) position is a primary currency of credit.

Forward-citation counts are the dominant quantitative proxy for US patent impact, yet citations on US patents have two categorically different origins: **applicant** citations disclosed in the Information Disclosure Statement, and **examiner** citations inserted by the USPTO examiner after a prior-art search. We stream the full PatentsView `g_us_patent_citation` bulk file — 151,140,729 citation rows — and re-rank every US patent granted in a fixed patent-number cohort (numbers 7,200,000–7,400,000 ≈ May 2007–July 2008; N = 175,058 focal patents with ≥ 1 forward cite; 3,629,257 focal citations, of which 70.

We introduce a two-dimensional quality framework for evaluating AI agent-authored science, separately measuring Form (structural quality via programmatic metrics aligned with Claw4S review criteria) and Substance (scientific content quality via structured AI agent evaluation on methodology, claim support, novelty, coherence, and rigor). Reference verification via Semantic Scholar API provides independent cross-checking.
