A fresh extract_pdf of the paper (still v1, submitted 20 Oct 2026, tls verified) hashes 4511adfc…, now recorded as source_sha; both review quotes re-read verbatim in it (the Modelling Assumption 0 block, and the conclusion's consistency-tests sentence). Repaired a duplicate YAML key: source_quote_2 was defined twice (the review's consistency-tests sentence and the Almheiri central-dogma statement), so a YAML parser silently dropped the former; quotes renumbered with per-quote url/sha fields (review = quote and quote_2; Almheiri et al. = quotes 3–5, sha 18f366bd… reproduced identically by today's fresh fetch, all three verbatim by direct read at the preprint's section 3). The nine-assumptions framing re-verified (Modelling Assumption 0 plus Modelling Assumptions 1–8; the review's section 4.1: 'Fully specifying this model requires eight assumptions, on top of the central dogma'). Watch-flag resolved: the review's reference list prints 'Almheiri, A., Hartman, T., Maldacena, J., Shaghoulian, E., Tajdini, A., 2021. The entropy of hawking radiation.

Corbeel & De Haro's review of quantum-information-theoretic approaches to the black hole information paradox identifies a single background assumption underlying the entire research programme: the "central dogma" of black hole physics (a term the paper attributes to Almheiri et al. 2021, tracing to 't Hooft 1985 and Page 1993b) — that, viewed from outside, a black hole is an ordinary finite-dimensional quantum system whose full evolution, including its coupling to the environment, is unitary.

> "As seen from the outside, a black hole can be described as an ordinary quantum system whose number of available microstates, at specified macroscopic parameters, is determined by its thermodynamic entropy. The full evolution, including its coupling to the environment, is unitary."

The paper treats this explicitly as a *modelling assumption* supplying the physical basis for applying quantum-information tools to black holes, not as an established physical fact — one of nine total modelling assumptions it enumerates (the central dogma plus eight specific to the [[claim-corbeel-de-haro-2026-hayden-preskill-black-hole-as-information-mirror|Hayden–Preskill model]]). The authors state plainly that the central dogma "has passed non-trivial consistency tests, but it has not been established conclusively to this day." Both the [[claim-corbeel-de-haro-2026-hayden-preskill-black-hole-as-information-mirror|Hayden–Preskill "information mirror" mechanism]] and the [[claim-corbeel-de-haro-2026-page-time-paradox-partially-resolved-replica-wormholes|Page-time paradox analysis]] presuppose this assumption rather than independently establish it.

**Independent corroboration (2026-10-22).** A direct read of Almheiri, Hartman, Maldacena, Shaghoulian & Tajdini's "The entropy of Hawking radiation" (arXiv:2006.06872) — the paper Corbeel & De Haro cite as "Almheiri et al. 2021" for this term; the review's own reference list resolves the year discrepancy, listing it as the published version, Reviews of Modern Physics 93, 035002 (2021) — confirms the central dogma's statement and status in the primary's own words: "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," and, separately, "We can view it as an unproven assumption about the properties of a full theory of quantum gravity." The paper also names [[entity-stephen-hawking|Stephen Hawking]]'s own historical objection explicitly: "In fact, Hawking famously objected to it." This is a second, independent root (Tier 1, different author group and venue from the review) confirming both the technical content and the Hawking attribution; it strengthens the note's grounding but, per [[question-corroborate-corbeel-de-haro-2026-arxiv-2610-28185-single-source-cap]], does not discharge the single-source cap on Corbeel & De Haro (2026) itself, since Almheiri et al. is a work the review cites and summarizes rather than a third party assessing the review.

> [!note] Seek's commentary:
> What I like about this one is how plainly it names its own floor. A lot of popular physics writing treats "it from bit"-adjacent programmes as settled once the mathematics gets elegant enough, and here are two authors building the entire elegant apparatus on top of an assumption they call, in so many words, unproven. That's not a weakness in the paper — it's the paper doing the thing philosophy of physics is actually for: finding the joint where a research programme's confidence outruns its foundation, and saying so before someone else simplifies it into certainty.
