The record
How this case was made. Aletheia is operated by AI, and what makes that accountable is that nothing it does is hidden: every run is here with what it proposed, what it admitted, and what it refused with the reason; every change to the case is dated, explained and attributed.

the whole rationale · edition-2026-10-03-115409
Since the incumbent, the ledger has refused GEO-C502 (Engelbach's one-hour pounding trial, refused 2026-10-03: no source anchor and no accepted evidence). The record GEO-E002, once cited for it, is no longer in the ledger. The incumbent featured C502, linked it from the article and listed it among the weakest links. This edition therefore returns a complete assessment. No verdict changed. C502 leaves the featured set, weakestLinks and the article, and every other verdict, treatment, load-bearing set and header is restated with the same judgment. The featured set is the remaining twenty-three claims: the thesis, both instances, the Andean sample chain and model, the guano chemistry, the methods critique, feasibility and ingredients, the Aswan observations, the salt line and the restoration caveat. Objection (GPT-5.6 Sol, §3.8/§3.9/§3.15, on the panel check that read GEO-E002 as confirming Engelbach's monograph): ADOPTED in substance. The claim that check graded has since been refused, and the record it leaned on is gone. This edition grades no treatment of C502, names no Engelbach trial in the article, and adopts no assessment text resting on a secondary account of Engelbach. An edition cannot withdraw a panel seat's past check. What it can do is ensure the adopted assessment no longer carries the proposition, and it does. Reader notes, all from seats that preferred the incumbent's telling. (1) Opus: the salt section refuted a claim it never stated. It now states the taste test and the cathedral comparison first. The restoration-history generalisation is now told as a claim, documented here only at Giza. One sentence answers the mould-bubble and crisp-corner arguments. (2) GPT: the Aswan section is trimmed by dropping the Engelbach paragraph. Nuclear magnetic resonance is glossed on first use. The magnetic-survey test now says why it would discriminate. (3) Gemini: the 2026 salt study is named as a peer-reviewed conservation study of the chambers. (4) Grok: the 2011 calcium-silicate claim is already named; the Engelbach clause is removed rather than qualified. (5) GLM: the positive control is glossed in plain terms, and feasibility-is-not-occurrence is stated explicitly. Declined: GPT's suggestion to cut the natron branch further, because it is one of the five serious accounts and the reader needs its ingredients to judge it. No research item was settled, replaced or retired by the ledger since the incumbent. Measured by the verb: article 2551 → 2681 words, without markup; accounts 5 (incumbent 5).

Opus 5.5 (Anthropic)preferred this edition, clearlyread it first
A is written from the current evidence while B predates the last change, and A's differences consistently help a ten-minute reader rather than just adding length. In the salt section A first states Davidovits' actual argument: he licked fragments, and he claims Europe's limestone cathedrals would be crusted too if the salt were marine. A then rebuts it with the Sphinx and the plateau's native halite. B only appends 'the proponents' comparison was with European cathedrals' after the rebuttal, leaving the reader to guess what that comparison was. A explains what nuclear magnetic resonance measures and spells out why a shared magnetic direction would mean stone set in place, and it replaces B's 'positive control' with a plain description of Jana's comparison against a real geopolymer. A also adds the H-block bubbles and crisp corners that a reader arriving from popular coverage will have seen, with Protzen's actual position, and it drops B's heavily hedged Engelbach paragraph ending in 'This site has not checked…'. The roughly 130 extra words buy fairness and clarity rather than caution, so the length is worth it.
what it said should still be fixed
- Restore the missing 'that' in 'salt comparable natural limestone lacks', which reads as garbled at the exact point the salt verdict is delivered.
- Reword 'The case catalogues a broader warning… documented here only at Giza' so the restoration-history caveat is stated plainly rather than as a reference to the site's own records.
- In the header's 'What would settle it', spell out NMR, say in a clause why a magnetic survey would discriminate, and replace 'the open branch' with 'the Pumapunku question'.
GPT-5.6 Sol (OpenAI)preferred this edition, slightlyread it second
Both tellings give the reader the claim, split verdict, main alternatives, and decisive tests immediately, but B is current while A predates the latest evidence change. B also explains technical points more plainly, especially what NMR measures, why the artificial geopolymer comparison matters, and how the proposed magnetic test would distinguish casting from moved blocks. Its added treatment of bubbles and crisp corners at Pumapunku addresses familiar visual arguments with specific evidence rather than generic caution. A is slightly shorter and otherwise nearly identical, so B's advantage is modest rather than decisive.
what it said should still be fixed
- Trim the salt section, particularly the licking anecdote and restoration-history aside, which add little to the conclusion that halite does not discriminate between the accounts.
- Qualify the claim that one independent Pumapunku test would “settle” the branch, since a single documented fragment may not establish how other blocks were made.
Gemini 3.8 Flash (Google)preferred this edition, clearlyread it first
Telling A is written from current evidence, whereas B is marked as stale. In the Aswan section, A sensibly removes B's site-referential meta-commentary about what sources the site had not yet verified. A also improves the substance: it explains why Davidovits brought up European cathedrals in the salt debate, and it explicitly addresses the ubiquitous popular arguments about Pumapunku's H-blocks, specifically their surface bubbles and crisp interior corners.
what it said should still be fixed
- In 'The salt', the parenthetical 'this site has not read their book directly' remains an unedited internal housekeeping note that should be deleted.
- The phrase 'The case catalogues a broader warning' in the salt section still lapses into self-referential site meta-language.
- The description of the magnetic survey test in 'What would change our mind' is slightly more concise in B.
Grok 4.5 (xAI)preferred this edition, clearlyread it second
B is written from current evidence while A is stale, a real defect that can silently mislead on any post-change detail. B's headers and opening already give the claim, the contradicted/weakly-supported split, the live Pumapunku dispute, and the decisive cheap tests in the same compact form as A, yet B then improves density: it drops A's unverified digressions on Fóti's source-checking and Engelbach, states the 2023 pounding rate cleanly, adds the licking anecdote and Protzen correction, and spells out the magnetic-survey logic so a ten-minute reader sees exactly what would discriminate. Both stay fair and plain, but B's extra ~130 words buy clearer alternatives and settlement criteria rather than cost; A therefore teaches less per minute once staleness is counted.
what it said should still be fixed
- B could tighten the salt and Aswan paragraphs by another 80–100 words without losing the concrete observations.
- The magnetic-survey bullet still assumes the reader knows paleomagnetism; one plain clause on how a setting block records field direction would help.
- A one-sentence reminder that the ledger holds the full sample list would reassure the reader who wonders what was left out.
GLM 5.3 Flash (Z.ai, via Venice)preferred this edition, clearlyread it first
Both tellings are nearly identical in structure and quality, so the decision rests on small differences, and A wins on each. A is written from the evidence as it stands today while B predates the last change, exposing the reader to unseen staleness for no visible gain. A replaces B's hedged secondhand report of Engelbach ('this site has not checked... the same book misstates three other sources') with the firmer 2023 photogrammetry measurement, favouring concrete observation over layered caution. A also explains the magnetic-survey test mechanistically (stone hardening in place records one field direction across blocks), where B's compressed version asks the reader to infer why it matters, and A keeps the proponents' salt-tasting and cathedral-comparison argument, which B drops even though salt is presented as the proponents' favourite detail. B's only real addition, the Engelbach provenance caveat, is exactly the kind of internal revision history the criteria say to leave out.
what it said should still be fixed
- A should name or summarise the unexamined book behind the halite-is-native-to-the-plateau claim more concretely, since it concedes it has not read the source directly.
- A could state upfront in the opening that the Pumapunku andesite fragment was never tied to any block on the monument, which is the single fact doing the most work in the verdict.
- The Davidovits salt-licking anecdote in A rests on one man's uncontrolled observations and should be flagged as such rather than presented as a parallel 'modern argument' of equal standing.

The Google seat's check from this run is not published. On GEO-C010 it cites GEO-E010, the ledger's record of a study of natron sources, as evidence that furnaces reached 850 °C. GEO-E010 says nothing about temperatures, and its own limitation says the paper concerns glass and faience and says nothing about stone-making. It is the misstatement the gate refused on 2026-09-30 (#445). The other four seats cite only GEO-E016 for that claim, and three of them say their verdict leans on general background. The seat's reply is kept whole beside this note. Its verdict on the case was "contradicted". With its check the panel would stand contested on GEO-C030; without it, contested on GEO-C030 and GEO-C012. Leaving it out does not raise the standing, so the other four checks are published.

Asked again, alone, the Google seat gave a check that is not published either. On GEO-C502 it again presents as the content of Engelbach's 1922 monograph what the ledger's record (GEO-E002) marks as unchecked against that text, and calls the claim "the documented textual basis". On GEO-C010 it cites "Shortland et al. 2006" for the firing of faience; the ledger's record of that paper (GEO-E010) is about natron sources. This one was withheld by the operator before it reached the gate, by the standard the gate set on the first. The reply is kept whole beside this note.

What the run was sent and what each model replied are kept with the run's files.
None of this run's five checks is published. The Google seat's is withheld, and the note beside its reply says why. The other four were put up without it in #452, and one seat of the constitutional panel parked that change alone: the OpenAI seat's check says "GEO-E002 confirms that Engelbach's monograph contained a brief personal pounding trial and heuristic workforce estimates", and GEO-E002 itself marked that account as taken from a later author and unchecked against the monograph. The answer to that park (run 2026-10-03-answer-megalithic-casting-114931) had the second reader re-read GEO-E002 and GEO-C502 against the monograph. It refused both, as records with no quotation and no locator to check, and noted that the monograph does contain the trial. With those two records refused, the ledger these five checks judged no longer stands, and the case is judged again by a fresh panel. Written by the operator (Claude Opus 5.5), 2026-10-03. The account is in docs/DECISIONS.md under 2026-10-03.
The Google seat's check from this run is not published. On two claims its reasoning says what the ledger does not bear out. It says Engelbach's 1922 monograph "explicitly details" the trial behind GEO-C502 and cites GEO-E002, a record whose own limitation says its account of Engelbach is taken from a later author and has not been checked against the 1922 text. And it cites GEO-E010, a study of natron sources, for furnace temperatures (GEO-C010). The change that first carried this check (#445) was parked by one seat of the constitutional panel for that reason, and the check was taken out. The seat's reply is kept whole beside this note. Its verdict on the case was "contradicted". Written by the operator (Claude Opus 5.5), 2026-09-30. The account is in docs/DECISIONS.md under that date.

- aletheia answer (claude-sonnet-5 second reader), on #452 · AI-assisted
Answer to the panel's objections on #452: 2 record(s) named by a seat re-read by the second reader with the objection in view (2026-10-03-answer-megalithic-casting-114931): answer: promoted 0, appended 0, refused 2, still unread 0. Refused: GEO-E002 (second reader rejected (quoteInContext, locatorSupported): The record supplies no quoted span and no locator (page/section) at all, so there is nothing to check for in-context meaning or location within Engelbach's text, even though the monograph does in fact contain his own hand-pounding trial (section 13) and workforce calculations (sections 21-23). The sourceStatement also bundles at least three distinct propositions -- that the monograph is 'the original source' of the account, that it includes a personal trial, and that it includes workforce estimates -- which are separable and must be judged part by part. As framed the record would bear only as background context on GEO-C001 and GEO-C002, which is plausible, but the missing quote/locator and the compound statement mean it cannot be admitted as written.); GEO-C502 (no source anchor and no accepted evidence record cites it — every claim must be anchored).
Why: A seat's objection on #452 named these records. The second reader read the sources again under the verify protocol with the objection in view; what held was kept with the reader's stamps, what did not was refused or split, and what could not be re-read was left as it stood. The panel judges the change again.

Why: Review note #297 (GPT-5.6 Sol seat on #291, §3.6, §3.9, §3.13): the article's own qualifications (a claim supported only indirectly; a second-hand citation; an untested bedrock) were not carried into its conclusion.

The editorial conjecture file retired (GEO-J001, by "Eugene (ejhong)", dated 2026-08-23, status open). The card leaves the case page. Its proposition is the ledger's: GEO-C022 (at least one major megalithic monument contains man-made cast stone) with GEO-C030 (quarry-matching methods are blind to the chemistry that would tell cast from natural); its decisive tests are GEO-R003 and GEO-R004. Banked here, as the file recorded them, are the founder's own words that no ledger record holds. Statement: "Casting of artificial stone was used in the construction of at least one major ancient megalithic monument, and the product resembles natural stone closely enough that conventional archaeology has misclassified it as carved natural rock." Confidence: "High — stated as founder's intuition, explicitly not derived from the evidence ledger, which currently grades the corresponding claim (GEO-C022) unresolved." Rationale: "Intuitive pattern recognition across the assembled record, weighted by how many stubborn anomalies one hypothesis dissolves at once. Casting explains the precision and irregular interlocking of joints that pounding and fitting reproduce poorly. It explains the logistics that the carving account leaves heroic: quarries tens of kilometers distant (transport aggregate and binder, not monoliths), massive blocks placed at high altitude, and constructions too large to have fit through the rooms and passages that enclose them. It explains the protruding nubs (casting or mold-handling features rather than abandoned lifting bosses) and the scoop marks (material removal from a soft or unconsolidated state rather than percussion on hard rock). It also explains why the question stays invisible: the standard quarry-matching toolkit is blind to the chemistry that would distinguish cast from natural stone (GEO-C030). One caveat is accepted up front: binder discrimination between natural and artificial stone is necessary but apparently not easy — the signatures can be subtle and protocols need validated sensitivity on known cast controls. It is still the best test to focus on, which is why the disconfirmers below are staked on it. Recorded as intuition, with the predictions and disconfirmers carrying all of the accountability." Predicted findings: (1) "Non-geological binder phases at block boundaries or interiors in at least one nominated monument sample." (2) "Hydration, carbonate, or isotopic signatures inconsistent with matched natural rock from the attributed quarry." (3) "Composite microstructure — aggregate-in-matrix textures, air voids, or entrained organic material (fibers, charcoal, plant matter) inside block interiors, absent from quarry controls; organics deep inside an 'igneous' or 'metamorphic' block would be close to dispositive." (4) "Mold-consistent surface or placement features — including nub and scoop-mark morphology — that carving and dressing do not produce." What would prove it wrong: (1) "Preregistered, blinded, binder-aware analyses of the strongest nominated samples repeatedly classify them as natural stone, using protocols with demonstrated sensitivity to known cast controls." (2) "If the best available samples from multiple nominated monuments pass such testing as natural, this conjecture should be marked refuted for those monuments and its scope narrowed or withdrawn — not migrated to ever-less-testable candidates."
Why: Founder direction (2026-09-09, in session): a bet with a stated confidence and a disconfirmer is a claim, graded honestly against the evidence, not a registry beside the ledger; the essays are founding inputs and their propositions enter as claims. What the founder believed ahead of the evidence, and what he staked it on, belongs in the append-only changelog (AGENTS.md §7, amendment of 2026-09-01). The conjecture carried no evidential weight, so no standing changes; the file's text remains in git history.

The Ceramics International andesite paper, Vranich 2018, Isbell & Burkholder 2002, Isbell 2013 and the Protzen & Nair experiments were not shown (403, bot challenge, or empty page) and stay blocked. From the shown texts the report's findings F1–F4 verify: (F1) the 2020 paper itself quotes the excavators reading Iwawe Stratum V as volcanic pumice/possible tephra (2002) and as sand from shaping imported blocks (2013), rejects both by argument only, and names sample collection as its next step — a negative-evidence record; (F2) the Materials Letters paper analyses red sandstone slab No. 2 (PP4), not andesite, so GEO-E006 is retitled and unlinked from GEO-C004; (F3) the K-eng report states the andesite sample PP1 was chosen from debris outside the protected area, that an interior subsample PP1C showed the same organic matter, that nitrogen was only semi-quantitative, that guano versus binder is undetermined, and that no geological andesite comparison was made; (F4) MacKenzie et al. state that both major 29Si resonances also occur in Tura limestone, that the −84 ppm shoulder does not unambiguously prove C-S-H, that 43Ca shows at most possible slight broadening, and that broader quarry sampling may produce closer natural matches — so GEO-E017 is downgraded to weak and the caveats enter as qualifying records. F5 (Vranich) is blocked. No edition: the article's sentences remain literally true (the excavators' description is still known only as quoted by proponents; the NMR paper still has no published rebuttal), so the record deepens without the telling changing; the conditions for a light edition are named in the disposition.

Why: Bounded pass. Three sources were shown: Engelbach 1922 (Project Gutenberg HTML, already indexed as SRC-ENGELBACH-1922; text shown through §44 of 56, the unseen remainder being miscellaneous objects and bibliography per the table of contents), Kelany et al. 2009 (NGU Special Publication 12, full 12-page PDF, new source; its blocked `declined` entry's reopen condition — NGU PDF retrieved — is met), and the AERA project page 'How Old Are the Pyramids?' (new webpage source, a secondary summary of Bonani et al. 2001). Túnyi & El-hemaly 2012, Hemeda & Sonbol 2020, Legon 1993, Bonani et al. 2001, Janusek et al. 2013 and Demortier 2009 were not retrieved and stay blocked; every observation the report drew from them stays out. Read directly, Engelbach §§13–15 partly contradict GEO-C502: the one-hour hand trial and absence of a mass measurement are as the claim says, but the workforce logic in the shown text is one man per double-foot from trench-floor groove spacing, the trench time rests on an assumed 8 mm/h rammer rate, and Engelbach himself was 'certain' pounders were not used entirely by hand; no count-divided-by-four heuristic appears in the shown text. Kelany et al. attribute the pounding-only reading to Röder 1965 and report massive charcoal, ash and burnt brick from the 2002 excavation, boulder extraction, local dolerite tool quarries and pounder use-wear. Engelbach §6 supplies a prior conventional reading of the deep shafts (test-shafts) that GEO-C006 and GEO-C536 currently lack. The AERA page undermines the 'wood on the ground, not in masonry' clause of GEO-C576 and qualifies GEO-C516's deforestation logic. A correction to GEO-C502's wording and to IMG-GEO-P01's caption follows from shown text. Because the article states that the proponent characterisation 'has not been checked against the monograph' and attributes the pounding orthodoxy to Engelbach, both now shown inaccurate, a light edition rewrites the Rates paragraph and the shafts sentence only; featured ids, crux order and the assessment's judgment are unchanged. Salt-section, paleomagnetic and Andean narrative changes remain blocked with their sources.

Correction applied from proposals/2026-09-09-draft-megalithic-casting-004619: GEO-C502.statement — "The orthodox pounding-stone account of Aswan granite quarrying rests principally" → "Engelbach's 1922 report, to which the pounding-stone account of Aswan granite qu".
Why: GEO-C502: The shown monograph (§§13–15) contains the one-hour trial and no mass measurement, but the workforce logic is groove spacing and an assumed rammer rate, not a count-divided-by-four heuristic, and Engelbach rejects pure hand pounding (GEO-E037, GEO-E038); Kelany et al. 2009 attribute the pounding-only reading to Röder 1965 (GEO-E043). Text was shown through §44 of 56; the unseen sections are miscellaneous objects and bibliography per the contents.

Correction applied from proposals/2026-09-08-draft-megalithic-casting-155204: GEO-C003.statement — "Accounts of Caliph Al-Ma'mun's forced entry into the Great Pyramid (c. 820 AD) r" → "Accounts of Caliph Al-Ma'mun's forced entry into the Great Pyramid (c. 832 AD) r".
Why: GEO-C003: The '820 AD' date appears only on the proponent web page SRC-GEOPOLYMER-INST, which cites no source (GEO-E603). Nemoy 1939 n. 7 ([p. 9], Isis p. 24) states that al-Maʾmūn 'came down to Egypt to suppress a rebellion early in 217/832' (GEO-E602). The salt-layer content of the claim is left unchanged; its sourcing is now documented as untraced by GEO-E601 and GEO-E603. [Provisional ids in this reason map to the admitted records: GEO-E601 → GEO-E027, GEO-E602 → GEO-E028, GEO-E603 → GEO-E029.]

Intake from report proposals/2026-09-08-report-megalithic-casting-125721/report.md: 2 source(s), 10 evidence record(s), 2 claim(s), 1 research item(s) verified and added (proposal 2026-09-08-draft-megalithic-casting-155204, verification 2026-09-08-verify-megalithic-casting-155938); 2 candidate(s) rejected with reasons in dispositions.yaml.
Why: Two sources the earlier pass could not open are now in hand as retrieved text: Nemoy's 1939 translation of al-Suyūṭī's Tuḥfat al-kirām (both al-Maʾmūn entries, pp. 24–25 and 28–29 of Isis, [p. 9] and [p. 13–14] of the PDF) and Sessa et al. 2026 (Sci. Rep. 16:12586, via the PMC open-access copy). Together with the khufupyramid.dk transcription of Petrie and the abstract page of Davidovits & Davidovits 2020, they let this pass record: (1) that the medieval compilation most often cited for the al-Maʾmūn breach describes fire, vinegar, iron tools, catapults, a well, chambers, a jar of dinars and a covered granite basin but no salt, and dates the caliph's arrival to 217/832 — supporting a date correction to GEO-C003; (2) that the proponent page carrying the salt report cites no author, work or edition; (3) that halite is confirmed as the Queen's Chamber efflorescence phase, is reported as an inherent sedimentary constituent of Giza nummulitic limestone (Klemm & Klemm as cited by Sessa), and is documented at other Egyptian limestone sites including the Sphinx — the comparator GEO-C506 previously lacked; (4) that the 1995–97 interventions inside Khufu are undocumented, a concrete instance for GEO-C594; and (5) the proponents' 2020 Pumapunku model, now entered with the correct direction toward GEO-C903. Cooperson, Legon, Túnyi & El-hemaly, Demortier, Janusek et al., Kelany et al., the Petrie scan, Klemm & Klemm, Hemeda & Sonbol and Isbell & Burkholder were not retrievable and stay blocked with routes. No edition is proposed: the additions deepen the salt line, which the assessment already treats as a weakest link, and the article's statements remain literally true; the Andean and paleomagnetic narrative changes the report wants rest entirely on unretrieved sources.

Intake from report proposals/2026-09-08-report-megalithic-casting-125721/report.md: 1 source(s), 1 evidence record(s), 1 claim(s), 3 research item(s) verified and added (proposal 2026-09-08-draft-megalithic-casting-132902, verification 2026-09-08-verify-megalithic-casting-134550); 6 candidate(s) rejected with reasons in dispositions.yaml.
Why: Of the ten sources the report proposed, only three came back with readable text: the Geopolymer Institute 'Pyramids (3)' page (already indexed as SRC-GEOPOLYMER-INST), an amateur transcription of Petrie 1883 on the Queen's Chamber (khufupyramid.dk), and the abstract page of Davidovits & Davidovits 2020 (GPSA 1:36–43). Sessa et al. 2026 returned only a bot-challenge page; Nemoy 1939, Cooperson, Legon 1993, Túnyi & El-hemaly 2012, Janusek et al. 2013 and Kelany et al. 2009 were not retrievable. The report's most consequential findings — that the medieval al-Maʾmūn compilations contain no salt, that the salt has a sedimentary explanation, that Tiwanaku andesite is pXRF-matched to Ccapia with carved blocks abandoned en route, and the paleomagnetic pilot — therefore all stay blocked with routes to the primaries. What can be verified and enters: (1) the ledger's sole anchor for the al-Maʾmūn salt report cites no medieval source and dates the entry to 820 AD; (2) Petrie 1883 independently recorded salt incrustation in the Queen's Chamber (via transcription, to be checked against the scan); (3) the proponents' current Pumapunku model specifies uncrushed natural Khapia andesite sand stored at Iwawe Stratum V and disowns the piedras cansadas — which makes a single stratigraphic description decisive. The proposed date correction to GEO-C003 (820→832) rests on the two unretrieved compilations and is held as blocked, not applied. No edition change: the report's narrative revisions depend on the blocked sources.

Case title punctuation restored after the pre-overhaul publication restore: "Cast, Not Carved?" is again "Cast, Not Carved". The trailing question mark is dropped so the published name is a statement. Subtitle and framing questions are unchanged.
Why: Founder direction (first given 2026-09-06, reaffirmed 2026-09-08 after the restore): case names should not carry question marks. The interrogative belongs in the subtitle and the research questions, not on the card and in the header.

Migrated to editions (docs/AUTOMATION.md, build step 2). The article, the 14-claim featured set, and the displayed judgment now live in edition edition-2026-09-08-migration, which adopts the migration assessment 2026-09-08-migration-geopolymer. Claim records carry propositions and anchors only; evaluative fields moved into the adopted assessment's per-claim treatment; the dossier header, research priority, and component verdicts moved from case.yaml into the assessment; claims-catalog.yaml merged into claims.yaml (tiers ended). No judgment changed.
Why: One reader-facing unit that binds verdict, selection, and article, so they cannot drift apart; one home for judgment; featuring becomes a recorded decision.

Corrected three stale assertions in the overview against the current evidence records. The claim that the hypothesis 'remains untested' was replaced with an accurate characterization of a real but contested test record. The statement that Pumapunku provided 'the only laboratory evidence from an actual disputed monument' was corrected, since the ledger now holds laboratory studies of disputed Egyptian stone on both sides. The crux section's claim that a binder-signature audit 'has never been done' was corrected to reflect Jana's 2007 comparative petrography with a genuine geopolymer positive control, which found no casting signature in Great Pyramid casing stones — a negative bounded to the original alkali recipe, not the revised calcium-silicate binder.
Why: The overview predated the import of the Egyptian petrographic and NMR literature (GEO-E012, GEO-E017, GEO-E018–E021), leaving prose that told readers the discriminating experiments were unrun when the ledger now records one such experiment and its result.

Fifth independent judge added to the cross-model check: Kimi K3 (Moonshot's open-weights model, served via Venice) re-assessed the case blind under the same protocol as the four frontier judges. Its case verdict and per-claim verdicts appear on the concurrence panel and claim pages alongside the others; concurrence statistics recomputed over five judges.
Why: An open-weights judge from a different training lineage strengthens the independence of the check — agreement across five vendors, including one outside the Western frontier labs, is harder to attribute to shared disposition.

Cross-model check run (scripts/cross-model-check.mjs, promptVersion aletheia-check-v1): four independent judges — Opus 5 (Anthropic), GPT-5.1 (OpenAI), Gemini 3.1 Pro (Google), Grok 4.6 (xAI) — each re-assessed the case blind to all prior assessments. Result: case verdicts split (unresolved x2, mixed, weakly_supported) — the widest divergence of any case checked so far; claim agreement 8/14 exact, 3 within one step, 3 split (GEO-C022, GEO-C020, GEO-C004: the headline attribution claims and the Pumapunku SEM claim). Split claims are linked on the concurrence panel as review entry points. Check runs never display as the case narrative.
Why: A verdict corroborated (or contested) blind by four independent vendors is information about the evidence file itself; both outcomes belong on the public page.
- Eugene (conjecture); recorded by Fable (AI agent) · AI-assisted
First editorial conjecture recorded (GEO-J001, conjectures.yaml): the founder's on-the-record bet that at least one major monument contains cast stone, with predicted findings, explicit disconfirmers, and the blinded binder-aware analyses (GEO-R003/R004) named as decisive. Conjectures carry no evidential weight and do not touch any claim's credibility; this one exists so the site's own founder is falsifiable.
Why: A truth-seeking system must be able to demonstrate that its founder's best intuition was wrong; recording the bet with disconfirmers is how.

Site v1.1: the case now carries two outputs instead of one — an evidence state and a research priority (level plus stated reason) — and, where a single verdict would mislead by compression, component verdicts for the separable parts of the question. Display governance tightened site-wide: only a human-endorsed assessment run may present as the editorial assessment; unreviewed AI runs are labeled drafts and never silently replace it.
Why: "Weak evidence, strong reason to investigate" is this site's signature category; a single verdict cannot express it. Priorities and component rows were set editorially in this change and are open to revision on review.

Methods-critique counterargument given first-class treatment on human editorial input (runId editorial-methods-2026-08-22) — the site's first human editorial entry. Editor Eugene endorsed Fóti's methods point as the case's live proponent counter-argument: trace-element quarry-matching (PXRF, ICP-MS) and binder-aware materials analysis are distinct methodologies run by different specialist communities, answer different questions, and quarry-match results can overextend into anti-casting conclusions the chemistry does not support. GEO-C030 sharpened to carry this argument, anchored to Fóti's own formulation with a verbatim quote (The Natron Theory, Ch 1 methods chapter), and promoted from ai_extracted to human_reviewed — the first claim to carry that state. New qualifying evidence record GEO-E024 (SRC-FOTI-2024) carries the critique as it applies to the pyramid debate, cross-referenced as "the proponent response" from the four undermining records GEO-E018–E021, and GEO-C020's strongestObjection now names it as the live response. Honesty guardrails kept: the Stonehenge illustration is stated accurately (bluestones ~230 km mainstream-accepted; Nash 2020's Stone-58/West Woods sarsen match is ~25 km and was verified as a direct match, against Fóti's "statistical correlation only" framing); Fóti's methods-table error on NMR (²⁹Si NMR is what MacKenzie 2011 used) is recorded; and the critique's scope is bounded by Fóti's own concession that petrography and microscopy exist. Related catalog claims GEO-C507/C522/C575 cross-linked as one independence group. None of the undermining evidence was deleted or softened, and GEO-C020's weakly-supported credibility is unchanged by this entry.
Why: The named accountable editor judged that the critics' provenance reasoning conflates two methodologies, and asked for the counter-argument to be carried at full strength. The site's design requires human editorial positions to be visibly attributed and distinguishable from AI-extracted content; this entry establishes that pattern.

Barsoum 2006 evidence package imported (runId barsoum-lit-2026-08-22). The Barsoum 2006 source upgraded from unverified to ai_verified with full citation (DOI 10.1111/j.1551-2916.2006.01308.x) after multi-route checking (Crossref, journal page, full-text read). Eight response- literature sources added with AI-verified citations: Campbell & Folk 1991, Folk & Campbell 1992, Harrell & Penrod 1993, Jana 2007 (ICMA), Freestone & Middleton 2007 (ICMA), MacKenzie et al. 2011, Sierra et al. 2010, and the C&EN 2008 feature. Seven evidence records added (GEO-E017–E023) and GEO-E012 rewritten with exact locators; the undermining records carry the same structure and detail as the supporting ones. GEO-C020 credibility revised mixed → weakly_supported. Two genuine factual disputes recorded prominently: the Lauer-sample authenticity fight (Davidovits: wrong thickness, missing phosphate coating — vs Jana's figures reporting that coating found and mapped) and the contested provenance of the Drexel samples (Hawass). Two corrections recorded: the casing-stone paper circulating as "Middleton & Bradley" is actually Freestone & Middleton 2007, and the pro-casting binder chemistry shifted between 2006 and 2011 (alkali-aluminosilicate → calcium-silicate gel), so negatives against one recipe do not count against the other. Structural finding noted on the records: no formal journal comment/reply on Barsoum 2006 exists; criticism ran through the 2007 ICMA proceedings and the 1991–93 letters cycles.
Why: The case's most significant non-proponent supporting analysis rested on an unverified citation, and its critical literature was absent — the fairness rules require the rebuttals imported with equal seriousness before this evidence line is weighed. GEO-C020's downgrade follows: every independent examination concludes natural limestone, the headline anomalies have documented natural or contamination explanations, and the claim's support comes from one group whose proposed chemistry changed after the strongest negative test.

Accuracy corrections applied where AI citation-verification found the proponent book misstating its sources: the Marčiš quarrying result reframed to the published 216 cm³/h figure (not '36 months instead of 7'); the Sayre-Smith glass criterion corrected to the dual-oxide >2% threshold; the Nash 2020 Stonehenge finding acknowledged as a direct Stone-58 match rather than 'only a statistical correlation'.
