The code that erased its own sources
Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).
Claim (verbatim)
Maimonides built the Mishneh Torah as a self-standing law: fourteen books of ruled halakhah in his own Hebrew, deliberately and programmatically without citing sources - he says as much in the introduction, promising a code one could read in place of the whole prior literature. That choice made the work a citation black hole. Every ruling has an ancestry - Mishnah, the two Talmuds, the halakhic midrashim, and a heavy but silent debt to geonic writings - but the code names none of it, which is why an entire genre of source-hunting (the Maggid Mishneh, the Kesef Mishneh, down to the modern Frankel apparatus) grew up around it, and why some rulings resisted source-identification for centuries: where Maimonides leaned on a geonic responsum or a reading now lost, the code preserves the ruling while destroying the pointer back to it. Mechanism: a source survives partly by being cited, and a code that cites nothing converts its sources into anonymous law, severing the quotation-trail that recovery needs. Prediction restated: the density of explicit external source-attribution formulae in the Mishneh Torah is a small fraction of that in a citing code of comparable scope such as the Tur - the measurable signature of a work that swallowed its own bibliography, and with it the traceability of the lost geonic layer beneath.
Prediction clause (verbatim)
Prediction: counting explicit external source-attribution formulae (naming a tractate, a named sage, or "the Geonim" as authority) per 10,000 words across Sefaria's machine-readable Mishneh Torah versus the Arba'ah Turim (Tur), the Mishneh Torah's rate will be under one-tenth (a ratio < 0.1) of the Tur's - primary clause: the < 0.1 Mishneh-Torah-to-Tur source-formula density ratio; the verdict follows it. Internal self-references ("as we explained in Hilkhot...") are excluded so that only outward source-attribution is counted; the test voids for coverage if either code is under 80% digitized.
Kill-dataset (verbatim)
Kill: Sefaria's open Mishneh Torah and Arba'ah Turim (Tur) - pattern-match external source-attribution formulae, normalize per 10,000 words, and compare densities, with the Frankel-edition source apparatus and the Kesef Mishneh as the control on what the Mishneh Torah left unnamed. Distinct from an internal cross-reference audit: only outward source-attribution is scored.
Nobody has run this test. The kill-data is named above. If you can run it — or you know the paper that already settles it — claim the kill or submit the prior scholarship. Kills and prior scholarship are credited here, by name, as they come in.
Provenance
Run: Fresh agent generation · model: claude-fable-5
Fresh blind generation by claude-fable-5, 2026-07-17, Jewish text-culture wave instrument-anchored on the open Sefaria corpus and its cross-reference link data, with standard critical editions as controls: every kill names a real corpus and a countable operation (coverage maps, citation-formula counts, link-orphan shares, digest-fraction, recension divergence, citation-decay), thresholds far from 1 with explicit coverage guards distinguishing what Sefaria holds from what existed. Ground is CITATION-GEOMETRIC and disjoint from the 2026-07-10 w19 Jewish wave, which was material-culture-of-loss (colophons, parchment, genizah, masora, binding fragments): no material-culture re-posing here. Two candidates were dropped after a grep of all fresh packets: a Tosafot-density-by-tractate survival item (pre-empted by w02-philosophy #18, which already correlates per-folio Tosafot density with manuscript survival), and a piyyut liturgy-vs-anthology survival item (pre-empted by w01-literature #28 'Liturgy out-survives fame', keyed to Davidson's Thesaurus). The Mishneh Torah item here tests EXTERNAL source-attribution erasure vs the Tur (loss of source-geometry), deliberately distinct from minds-w02 #25, which tests the code's INTERNAL recall/promise cross-references. Two items are marked Kill (not yet built) where the deciding corpus (Kohut's Arukh apparatus; Lewin's parallel Iggeret recensions) is not yet digitized.
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
The design fact is printed in the primary source itself - Maimonides' introduction announces a code without source citations, the Rabad's stricture attacks the choice, and Twersky's Introduction to the Code analyzes both the program and the scattered exceptions ('the Geonim ruled', named teachers) at length - and the Tur's character as a densely citing code is equally standard. But neither code's source-attribution formulae have ever been counted, the Mishneh Torah's rate is small but not zero, and the < 0.1 per-10,000-word density ratio is a specific figure no reference work states or strictly guarantees. Direction print-established, arithmetic un-run.
