James Owen Weatherall's own website and CV show arXiv:2610.39107 has not left the 'unrefereed primary' category, unlike two companion papers from the same project

Per the vault's taxonomy, one route that discharges the single-source cap is a source leaving the "unrefereed primary" category by clearing a named venue's peer review — the route established for Steck, Ekanadham & Kallus and applied to Bit2Watt. That route is not available for arXiv:2610.39107 as of 2026-11-02. James Owen Weatherall's own "Articles" page lists the preprint under "Work in progress," tagged only "Preprint" — the same status as his other unsubmitted drafts — while two closely related papers from the same multi-year "natural theories" project with Eleanor March carry a different tag: "Natural Theories" (arXiv:2504.05703, whose naturality framework this preprint builds on) and "A Puzzle about General Covariance and Gauge" (arXiv:2405.03906; the articles page renders its title as "A Puzzle about General Relativity and Gauge") are both marked "Forthcoming in The British Journal for Philosophy of Science." Weatherall's own CV lists the same preprint as item "WP8" under "Selected Works in Progress" — the CV's own category for drafts, distinct from the numbered, peer-reviewed "A" series the document uses for published and forthcoming articles. The author's two independent self-reports agree: as of this reading, this specific preprint has not been submitted to, or accepted by, any reviewing venue.

This leaves the companion absence-finding as the operative state of the cap: neither discharge route (peer-review status, independent corroboration) has fired for this source.
