Evidence record DEEP-E016 explicitly confirms that the catalogue analysis reports a broad cosmic-serpent motif class in 37% of its sampled traditions. As the claim is restricted to whether the experiment's coded dataset reproduces that rate, the provided evidence is directly supportive. The strongest opposing consideration is that the figure originates from an unverified self-report operating over a dataset with acknowledged geographic sampling gaps.

DEEP-E016 reports the 37% figure as the site's own result, but it is a self-report with method and data not retrieved, and a second reader notes that DEEP-E017's quoted passage is a scope caveat rather than evidence for the number. DEEP-E018 further qualifies the catalogue's coverage. The figure is supported only as the page's statement of its own result.
Weakly supportedconfidence: moderate · GPT-5.6 Sol (OpenAI) — independent check run via gpt-5.6-sol · run 2026-09-09-check-gpt-210940 · unreviewed draft
DEEP-E016 directly reports the 37% figure, providing weak support for the experiment's stated result. DEEP-E017 only limits the result to the selected category and dataset, and DEEP-E018 notes uneven coverage. The strongest opposing consideration is that neither the coding nor the denominator and calculation can be audited from the supplied evidence.
Weakly supportedconfidence: low · Grok 4.5 (xAI) — independent check run via grok-4.5 · run 2026-09-09-check-grok-210940 · unreviewed draft
E016–E017 report the 37 % cosmic-serpent frequency; E018/E019 again qualify. Identical limitations of self-report and missing data apply. Strongest opposing consideration is the same scope caveat raised by the second reader: geographic and category limitations are not themselves confirmation of the percentage.
Weakly supportedconfidence: low · Opus 5 (Anthropic) — independent check run via claude-opus-5 · run 2026-09-09-check-opus-210940 · unreviewed draft
Identical footing to DEEP-C005: DEEP-E016 restates the 37% figure from the same unaudited page, DEEP-E017 is a scope caveat the second reader flags as not bearing on the number, and DEEP-E018/E019 are the author's coverage limitations. No independent access to the coded catalogue is on record. The strongest opposing consideration is again that the figure is a simple count from a published catalogue and could be checked easily — which is an argument for auditing it, not for crediting it now.
Weakly supportedconfidence: low · claude-fable-5-1 · run 2026-09-09-edition-210937 · unreviewed draft
Weak self-report record E016 states the 37% figure; E017 is a scope caveat whose 'supports' direction its second reader disputes. E018 and E019 qualify coverage and category reach.
Provisionally supportedconfidence: moderate · Gemini 3.8 Flash (Google) — independent check run via gemini-3.8-flash · run 2026-09-10-check-gemini-121549 · unreviewed draft
Directly supported by DEEP-E016, which records that the catalogue analysis found a broad cosmic-serpent class in 37% of sampled traditions. This remains provisional due to its reliance on self-reported data from an unverified web source (SRC-JHONG-2026) and the author's caveat that the finding is scoped strictly to this specific dataset and categorization (DEEP-E017, DEEP-E018). The strongest opposing consideration is that snakes are universal natural hazards, making snake-related myths an inevitable convergent development rather than a meaningful motif class.

DEEP-E016 supports the 37% figure only as a self-report, and DEEP-E017 is a scope-limiting caveat rather than corroboration of the number. The strongest opposing consideration mirrors C005: 'cosmic serpent' is a broad, definition-sensitive class coded on a dataset whose coverage the author himself flags as uneven, so the figure is unreproduced and fragile.
Weakly supportedconfidence: low · GPT-5.6 Sol (OpenAI) — independent check run via gpt-5.6-sol · run 2026-09-10-check-gpt-121549 · unreviewed draft
DEEP-E016 directly reports a 37% frequency for the broad cosmic-serpent class. DEEP-E017 through DEEP-E019 restrict the result to the selected category and unevenly covered dataset, and neither coding records nor calculations are available. The strongest opposing consideration is that these limitations affect generalizability more directly than they affect whether the site's own coded data yielded the stated percentage.
Weakly supportedconfidence: low · Grok 4.5 (xAI) — independent check run via grok-4.5 · run 2026-09-10-check-grok-121549 · unreviewed draft
E016 states the 37 % cosmic-serpent frequency; E017–E019 qualify scope and coverage. Again only a self-report is present. The strongest opposing consideration is identical to that for the bird-person figure: catalogue artefacts may inflate or deflate the rate.
Weakly supportedconfidence: low · Opus 5 (Anthropic) — independent check run via claude-opus-5 · run 2026-09-10-check-opus-121549 · unreviewed draft
DEEP-E016 reports the 37% figure and DEEP-E017 scopes it to the selected category and dataset; both are weak author self-reports with data not in hand. As with the bird-person figure, the claim asks whether the coded data reproduce the proportion, which no record here checks. Opposing consideration: the denominator and coding frame are unstated in the ledger, and DEEP-E018's coverage caveat bears directly on whether 37% is a stable estimate.
Weakly supportedconfidence: moderate · claude-fable-5-1 · run 2026-09-10-edition-121547 · unreviewed draft
DEEP-E016 records the page's report of 37%; DEEP-E017, DEEP-E018 and DEEP-E019 qualify its scope, coverage and class breadth. Same footing as DEEP-C005: a self-reported result of an unaudited coding.
Weakly supportedconfidence: low · claude-fable-5-1 · run 2026-09-19-edition-130205 · unreviewed draft
DEEP-E016 records the page's 37% figure; DEEP-E017, DEEP-E018 and DEEP-E019 qualify it. Weak self-report, data not retrieved.
Weakly supportedconfidence: moderate · Gemini 3.8 Flash (Google) — independent check run via gemini-3.8-flash · run 2026-09-28-check-gemini-140630 · unreviewed draft
Record DEEP-E016 documents the author's report that a cosmic-serpent class appears in 37% of sampled traditions within the catalogue. Records DEEP-E017, DEEP-E018, and DEEP-E019 qualify this by noting the scoped nature of the dataset and significant regional gaps in catalogue coverage. As with the bird-man catalogue results, the ledger contains only the author's textual self-report rather than the raw coded traditions or analytical replication data. The strongest opposing consideration is that semantic over-inclusiveness—aggregating rain serpents, ouroboros figures, and chthonic monsters into a single "cosmic serpent" category—artificially inflates the frequency to 37%.
Provisionally supportedconfidence: moderate · Gemini 3.8 Flash (Google) — independent check run via gemini-3.8-flash · run 2026-09-28-check-gemini-142201 · unreviewed draft
The 37% frequency for the cosmic-serpent motif is explicitly reported in record DEEP-E016 from the founder's catalog analysis, providing direct provisional support for the claim as stated. Nevertheless, records DEEP-E017, DEEP-E018, and DEEP-E019 emphasize that the finding is scoped strictly to that specific sampled dataset and is constrained by uneven catalog coverage in the Near East. The strongest opposing consideration is that the underlying Berezkin & Duvakin catalog data and specific coding rules have not been independently retrieved or verified within the ledger.
Weakly supportedconfidence: moderate · Gemini 3.8 Flash (Google) — independent check run via gemini-3.8-flash · run 2026-09-28-check-gemini-143733 · unreviewed draft
Evidence record DEEP-E016 supports the claim by quoting the author's self-reported catalogue finding of a 37% occurrence rate for a broad cosmic-serpent class, while DEEP-E017, DEEP-E018, and DEEP-E019 qualify the scope and highlight regional sampling biases in the underlying 2016 catalogue. Support remains weak due to the unaudited nature of the author's self-published preliminary research. The strongest opposing consideration is that the 37% metric is explicitly stated as the measured result of the catalogue experiment.

DEEP-E016 weakly supports the 37% figure as self-report; DEEP-E017 (per its second reader) scopes the geographic result rather than supporting the number, and DEEP-E018 notes the coverage caveat. The strongest opposing consideration is the same as for DEEP-C005: no coded data in hand, so the statistic cannot be reproduced or checked.

Same footing as DEEP-C005: DEEP-E016 reports the 37% figure as the author's own result, with method and data unretrieved and DEEP-E017/E018 flagging dataset-specific scoping. The number exists only as a self-report; nothing independent reproduces it.

A single weak support record (DEEP-E016) reports the 37% figure as the page's own result, with the second reader noting E017 only scopes the geographic finding rather than confirming the number. Method and data unretrieved. The strongest opposing consideration is the same as for C005: an unaudited self-report on a dataset the author concedes is unevenly covered cannot carry more than weak weight.
Provisionally supportedconfidence: low · GPT-5.6 Sol (OpenAI) — independent check run via gpt-5.6-sol · run 2026-09-28-check-gpt-140630 · unreviewed draft
DEEP-E016 directly reports the 37% cosmic-serpent frequency, while DEEP-E017 limits its interpretation to the selected category and dataset. DEEP-E018 and DEEP-E019 add concerns about coverage and broad coding. The strongest opposing consideration is that this is an unaudited self-report with no accessible coded data or method.
Weakly supportedconfidence: low · GPT-5.6 Sol (OpenAI) — independent check run via gpt-5.6-sol · run 2026-09-28-check-gpt-142201 · unreviewed draft
DEEP-E016 reports the exact 37% cosmic-serpent frequency, but it is only the author's statement of the site's own analysis. DEEP-E017 through DEEP-E019 restrict its interpretation to the selected category and unevenly covered dataset, and no coded data were retrieved. The strongest opposing consideration is the exact match between the record and claim, but it does not independently reproduce the proportion.
Weakly supportedconfidence: moderate · GPT-5.6 Sol (OpenAI) — independent check run via gpt-5.6-sol · run 2026-09-28-check-gpt-143733 · unreviewed draft
DEEP-E016 directly reports the claimed 37% cosmic-serpent frequency. DEEP-E017 through DEEP-E019 restrict its interpretation to the selected category and unevenly covered dataset, while the underlying coding and calculation remain unavailable. The strongest opposing consideration is that an unaudited author report does not establish that the experiment's data actually reproduce the number.
Weakly supportedconfidence: low · Grok 4.5 (xAI) — independent check run via grok-4.5 · run 2026-09-28-check-grok-140630 · unreviewed draft
DEEP-E016 restates the 37 % cosmic-serpent frequency as a self-report; DEEP-E017 and DEEP-E018 qualify scope and coverage. The figure therefore hangs on an unretrieved dataset; the opposing consideration is that broad narrative categories inflate apparent ubiquity relative to the specific feathered-serpent images that motivate the comparison.
Weakly supportedconfidence: low · Grok 4.5 (xAI) — independent check run via grok-4.5 · run 2026-09-28-check-grok-142201 · unreviewed draft
DEEP-E016 records the founder's 37 % figure for the broad cosmic-serpent class; DEEP-E017 and E018 qualify it as scoped to the selected category and uneven catalogue. Same self-report footing as C005. Strongest opposing consideration is identical: without the coded data the proportion cannot be audited and may reflect category breadth more than historical signal.
Weakly supportedconfidence: low · Grok 4.5 (xAI) — independent check run via grok-4.5 · run 2026-09-28-check-grok-143733 · unreviewed draft
Identical footing to the bird-person frequency: self-reported 37 % qualified by the page's own scope and coverage caveats, with no underlying data retrieved. Strongest opposing consideration is again unverified coding decisions and geographic undersampling that could move the percentage substantially.
Weakly supportedconfidence: moderate · Gemini 3.8 Flash (Google) — independent check run via gemini-3.8-flash · run 2026-09-30-check-gemini-103112 · unreviewed draft
The claim is supported by DEEP-E016, which directly records the founder's statement that the catalogue analysis identified a broad cosmic-serpent class in 37% of sampled traditions. Nevertheless, the evidentiary strength is weak because it represents an unaudited self-report from an unverified website, lacking primary access to the underlying data matrices or coding criteria. Moreover, DEEP-E017, DEEP-E018, and DEEP-E019 clarify that this baseline applies only to an aggregated categorical definition within a regionally uneven dataset. The strongest opposing consideration is that the 37% figure reflects a real quantitative extraction from the Berezkin comparative mythology catalogue that accurately measures the global ubiquity of serpentine mythic tropes.

DEEP-E016 reports the 37% figure on the same self-report footing as the bird-person claim; DEEP-E017 is a scope caveat, not numeric support. The catalogue data and method are unretrieved. The strongest opposing consideration is the same as for DEEP-C005: an unaudited self-report of a result whose coded data are not in hand.
Weakly supportedconfidence: moderate · GPT-5.6 Sol (OpenAI) — independent check run via gpt-5.6-sol · run 2026-09-30-check-gpt-103112 · unreviewed draft
DEEP-E016 reports the exact 37% cosmic-serpent frequency, directly supporting the claim at the level of the project's own account. DEEP-E017 through DEEP-E019 restrict the result to a selected broad category and an unevenly covered dataset. The strongest opposing consideration is that neither the coding nor the calculation is available for reproduction.
Weakly supportedconfidence: low · Grok 4.5 (xAI) — independent check run via grok-4.5 · run 2026-09-30-check-grok-103112 · unreviewed draft
E016 quotes the page's report of a broad cosmic-serpent class in 37 percent of sampled traditions; E017 and E018/E019 qualify geographic and categorical scope. Support reduces to the same self-report footing as the bird-person frequency. Strongest opposing consideration is again the absence of the coded dataset and the page's admission of uneven coverage.
Weakly supportedconfidence: moderate · Opus 5.5 (Anthropic) — independent check run via claude-opus-5-5 · run 2026-09-30-check-opus-053723 · unreviewed draft
One record (DEEP-E016) quotes the page's 37% figure for a broad cosmic-serpent class. DEEP-E017, DEEP-E018 and DEEP-E019 are the author's scope caveats. Nothing independent confirms the proportion, and the claim does not state its denominator, which I take from context to be the same catalogue sample. The strongest opposing consideration is the page's own warning that the geographical result describes only the selected category and dataset (DEEP-E017): 'cosmic serpent' is an umbrella from which the specific feathered-serpent image cannot be separated. Supported only as a self-report, the figure bears on the featured hypothesis not at all without a model of what frequency each history predicts.
Weakly supportedconfidence: moderate · Opus 5.5 (Anthropic) — independent check run via claude-opus-5-5 · run 2026-09-30-check-opus-103112 · unreviewed draft
E016 is the page's statement of its own 37% figure, unaudited. E017 confines the result to the selected category and dataset. E018 and E019 add uneven coverage and the gap between broad categories and specific images. The truth condition, reproduction from the coded data, is untested, but nothing in the ledger contradicts the figure. The strongest opposing consideration is that "cosmic serpent" is a broad, interpretive class whose frequency depends heavily on coding rules the ledger does not hold.
