question-corroborate-corbeel-de-haro-2026-arxiv-2610-28185-single-source-cap asked two things: what, if anything, corroborates Corbeel & De Haro's "Black Holes are about Quantum Information" (arXiv:2610.28185), and whether the held title-slogan finding (parked by the cap) should become the fourth claim-note. This capture researches both halves directly rather than re-deriving them from the preprint alone.

All sources below were fetched directly (extract_pdf for every PDF, archive_page for the one web page attempted) with verified TLS throughout. No recognition signals fired on any fetch — all four documents are plain academic prose (two arXiv physics papers, one DPhil thesis, one arXiv abstract page); none addresses an AI reader, claims special authority, or asks for anything outside normal citation. No ## Safety flags entries this session.

Claim: No independent source has engaged with Corbeel & De Haro (2026) as of 2026-10-22 — the single-source concentration cap remains undischarged, and the title-slogan claim does not yet earn the fourth slot

A search for citations, reviews, or third-party technical engagement with arXiv:2610.28185 turned up no independent author group discussing the paper. The paper's own arXiv abstract page lists no journal-ref and no citing works. The only related documents found were: (1) a PhilSci-Archive listing of the same paper — same title, same authors, dated 2025 (item 27365) — meaning the review has circulated in preprint form for roughly a year before this arXiv posting, not merely "one day"; and (2) a later arXiv paper, "Holography as an Information Principle in Quantum Gravity" (De Haro, Cinti & Corbeel, arXiv:2608.26282), which cites Corbeel & De Haro (2026) — but shares two of its three authors with the paper under review, so by the cap's own rule ("a later paper by the same authors... [is] the same source wearing different clothes") this is not independent corroboration. (philsci-archive.pitt.edu itself returned "Request Rejected" to both WebFetch and archive_page on the same route that served the listing text via web search — a new candidate for sources.md's known-blocked list, not confirmed further here.)

The three claims below (Hayden–Preskill, Almheiri et al., Timpson) are genuine Tier-1 primary reads, by different author groups in different venues, that independently confirm specific technical and philosophical content Corbeel & De Haro's review restates. But none of them corroborates the review as a source in the sense the cap requires: Hayden & Preskill (2007) and Almheiri et al. (2020) are works the review cites and summarizes, not independent assessments of it, and both predate it by years; Timpson's thesis (2004) predates it by 22 years. A primary that a review accurately summarizes is not the same as a third party confirming the review got the summarizing right — the former strengthens the floor under the vault's existing three claim-notes (two of which were flagged [unverified-mechanism]-adjacent, sourced only to "the review's own characterization"), the latter is what the cap's "independent source corroborates it" clause is actually asking for. On the plain arithmetic of sources.md's cap, that condition is still unmet. The title-slogan claim — definitional, Tier 1, and the most directly connective to the existing moc-a-shared-slogan-is-not-a-shared-model-adjacent cluster per the question's own held-finding note — remains well-formed and independently well-grounded (see the Timpson claim below), but neither its own merit nor the strength of its grounding is what the cap gates on. It should stay parked until an independent author group engages with arXiv:2610.28185 itself, or the paper's publication status changes its category.

Claim: Hayden & Preskill's own 2007 paper independently confirms the "information mirror" framing Corbeel & De Haro's review restates

A direct read of Hayden & Preskill's "Black holes as mirrors: quantum information in random subsystems" (arXiv:0708.4025; published JHEP09(2007)120) confirms, in the primary's own words, the mechanism the vault's claim-corbeel-de-haro-2026-hayden-preskill-black-hole-as-information-mirror currently sources only to the review's restatement:

"the (maximally entangled) black hole is hardly black at all — it is a quantum information mirror that returns to Bob the information Alice deposited almost as quickly as possible!"

"the black hole is a "mirror" in the sense that it returns Alice's information in a time comparable to the time it takes the information to fall into the black hole."

The paper's own closing section independently uses the exact "delicious irony" phrase the review quotes:

"In fact there is a delicious irony at the core of our analysis."

— referring to the fact that modeling black hole dynamics as a random unitary (meant to maximize concealment) simultaneously makes the black hole a near-optimal quantum error-correcting encoder, which protects information rather than destroying it. This is a specific technical-mechanism claim, directly sourced to the primary (Tier 1, different author group, different venue from Corbeel & De Haro) — it clears the sourcing floor independently of the review that restates it.

Claim: Almheiri et al.'s 2020 review independently confirms the "central dogma" term, its definition, and its status as an explicitly unproven assumption — including Hawking's own objection

Almheiri, Hartman, Maldacena, Shaghoulian & Tajdini's "The entropy of Hawking radiation" (arXiv:2006.06872) is very likely the paper Corbeel & De Haro cite as "Almheiri et al. 2021" for the central-dogma term (the discrepancy in year is unresolved here — arXiv v1 is dated June 2020; a later published version may carry 2021). The paper's Section 3, titled "The black hole as an ordinary quantum system," states the central dogma explicitly:

"As seen from the outside, a black hole can be described in terms of a quantum system with Area/(4GN ) degrees of freedom, which evolves unitarily under time evolution."

— the same statement Corbeel & De Haro's review paraphrases as the basis for claim-corbeel-de-haro-2026-black-hole-central-dogma-is-unproven-modelling-assumption. The primary independently confirms the "unproven assumption" framing central to that claim:

"We can view it as an unproven assumption about the properties of a full theory of quantum gravity."

and separately confirms Stephen Hawking's own historical objection to the dogma, named explicitly rather than inferred:

"In fact, Hawking famously objected to it."

The paper also states the term was "borrowed from biology, where the central dogma talks about the information transfer from DNA and RNA to proteins" — confirming the term's origin story as the authors' own coinage-by-analogy, not merely Corbeel & De Haro's gloss on it. This is Tier 1, a different author group and venue, directly read — it independently verifies both the technical-mechanism content and the historical attribution the existing claim-note carries.

Claim: Timpson's own thesis independently confirms the ontological-vs-methodological framing behind the review's title-slogan disclaimer

The parked title-slogan finding rests on Corbeel & De Haro's claim that their slogan follows Christopher Timpson's account in Quantum Information Theory and the Foundations of Quantum Mechanics. A direct read of Timpson's 2004 Oxford DPhil thesis (arXiv:quant-ph/0412063), the documented precursor to the 2013 book, confirms this independently, in Timpson's own words, in the thesis's own abstract:

"Accordingly, the slogan may not be understood as an ontological claim, but at best, as a methodological one."

This is the same ontological/methodological distinction Corbeel & De Haro's title-slogan disclaimer leans on, confirmed directly from Timpson's own primary text (Tier 1, different author, different venue, and 22 years prior) rather than taken on the review's word. It is a definitional/framing claim — the sourcing floor only requires Tier 3-4 for this kind, so Tier 1 direct confirmation exceeds what was strictly necessary. This strengthens the title-slogan claim's own grounding considerably, but — per the claim above — does not discharge the cap, since Timpson's thesis cannot corroborate a 2026 paper it predates by two decades.

Further leads

• Don Page's original 1993 result ("Average entropy of a subsystem," Phys. Rev. Lett. 71, 1291, arXiv:gr-qc/9305007) is cited directly inside Hayden & Preskill's own reference [12] — a further available primary for the Page-bound claim, not fetched this session; entity-don-page already exists in the vault.
• Gerard 't Hooft's 1985 paper is the other origin point Corbeel & De Haro (and, independently, Almheiri et al.'s broader literature) trace the central dogma to — not identified or fetched this session; the oldest unexamined link in this chain.
• The PhilSci-Archive 2025 listing (philsci-archive.pitt.edu/27365) for the same Corbeel & De Haro paper could not be read directly (site rejected both WebFetch and archive_page); only its indexed metadata was recovered via web search. Worth a manual-consultation attempt in a future session, and a candidate addition to sources.md's known-blocked list if the block repeats.
• De Haro, Cinti & Corbeel's "Holography as an Information Principle in Quantum Gravity" (arXiv:2608.26282) cites Corbeel & De Haro (2026) but shares authors with it — not independent per the cap's own rule, but worth reading directly if the vault ever wants a fuller picture of how this cluster of De Haro/Corbeel papers relates to claim-vinck-de-haro-2026-no-existing-definition-captures-wittens-background-independence-claim and the other Vinck & De Haro notes.
• Almheiri et al.'s paper states the central dogma is "not accepted by some researchers," without naming them beyond Hawking — a lead toward whoever else has formally objected, not checked here.

Entity candidates

• Gerard 't Hooft — person — the 1985 origin point Corbeel & De Haro cite (alongside Page 1993b) for the central dogma; the oldest foundational figure in the lineage this capture's corroborating claims rest on, not yet identified by primary source in the vault.
• Patrick Hayden & John Preskill — people — authors of the 2007 primary now directly read and quoted twice in this capture (information-mirror framing, "delicious irony"); previously flagged mention-only in the 2026-10-21 capture, now independently engaged with rather than taken on the review's word.
• Ahmed Almheiri, Thomas Hartman, Juan Maldacena, Edgar Shaghoulian, Amirhossein Tajdini — people — authors of "The entropy of Hawking radiation," the paper that appears to have coined "central dogma" in this context (borrowed from molecular biology) and the primary independently confirming its "unproven assumption" status.
• Christopher Timpson — person — his 2004 thesis (precursor to the 2013 book) now directly read and quoted, independently confirming the ontological-vs-methodological distinction underlying the parked title-slogan claim.
