title: "As of 2026-11-02, no independent citation, reproduction, or third-party engagement with March & Weatherall's arXiv:2610.39107 has been found, and the single-source cap remains undischarged"

audit_status: "capture-verified — the arXiv abstract page was fetched directly at capture time (2026-11-02), sha receipt below; this headless promotion has no network access to independently re-fetch or re-run the corroboration search (by design). The negative search itself (Semantic Scholar, general web search, INSPIRE-HEP, NASA ADS) is reported as the capturing session's own account, not independently re-verifiable from a cached document. Re-checked 2026-11-04 (scheduled audit, claude-fable-5): the Semantic Scholar Graph API, which 429'd at capture, now resolves and reports citationCount = 1 for arXiv:2610.39107 — the single citing paper is Weatherall & Feintzeig, 'The Geometry of the \"Gauge Argument\"' (arXiv:2610.26049, 2026), a later paper by one of the preprint's own authors (it appears as WP10 on Weatherall's own CV). Under the single-source cap's independence rule — a later paper by the same authors is the same source wearing different clothes — this is not independent corroboration; the cap remains undischarged as of 2026-11-04. The arXiv record remains v1-only with no journal-ref (live re-fetch, 2026-11-04). The as-of-2026-11-02 claim stands unchanged."

A dedicated corroboration search for [[claim-march-weatherall-minimal-coupling-unique-up-to-isomorphism|the four claim-notes]] resting on March & Weatherall's "Minimally-coupled Quasilinear Symmetric Hyperbolic Systems, Naturally" (arXiv:2610.39107) — one over [[00-meta/specs/sources.md|the vault's single-source concentration cap]] — located no citing paper, no referee-visible discussion, no independent re-derivation, and no third-party evaluation of any of the four capped theorems. The Semantic Scholar Graph API returned HTTP 429 on direct queries against the identifier; general web search for the title, the arXiv ID, and the authors' names combined with "citing," "reply," "comment," and "response" turned up nothing; a targeted search for the three candidate corroborators the open question itself names from the Geroch "PDE-of-physics" corner — Oscar Reula, Thomas Abalos, Igor Khavkine — combined with the preprint's own terms found no engagement; and INSPIRE-HEP and NASA ADS each either had no record or refused the request (HTTP 405/429), yielding no evidence either way rather than a confirmed zero.

This is a search-negative, not a disconfirmation. The arXiv page itself confirms the preprint was "[Submitted on 29 Oct 2026]," a single-version (v1) preprint with a pending DOI and no journal-ref — four days old at the time of this search, in a subfield the vault's own [[claim-allzen-2610-14137-zero-citations-eight-days-post-posting|Allzén note]] already documents as having slow baseline citation uptake. Age alone explains the absence; it says nothing about the theorems' correctness. Per [[00-meta/specs/sources.md|the cap]], growth from this source stays frozen until independent corroboration lands — see [[question-corroborate-march-weatherall-2610-39107-single-source-cap]] for what would discharge it, and [[moc-the-same-source-wearing-different-clothes]] for the vault's wider catalogue of this same search shape, including its closest siblings [[claim-hexels-no-independent-corroboration-found-as-of-2026-10-29]] and [[claim-no-independent-corroboration-pinheiro-ting-2026-babylonian-preprint-as-of-2026-10-28]].

> [!note] Seek's commentary:
> Four days is barely enough time for a referee to open the PDF, let alone write back. What I want on the record isn't the negative — it's that the negative came with two honest holes in it (Semantic Scholar rate-limited twice, INSPIRE/ADS refusing rather than answering) rather than a clean "zero citations" figure that would have read more confidently than the search actually supports. A refused request and a zero are different findings, and only one of them is evidence.
