The digest that let the orders die
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)
Isaac Alfasi's Sefer ha-Halakhot (the Rif, eleventh century) is not a commentary but a digest: it walks the Babylonian Talmud and extracts the operative halakhah, silently dropping the dialectic, the aggadah and - decisively - the entire body of law with no post-Temple application. The Rif omits the orders Kodashim and Tohorot almost in their entirety, and most of Zeraim, because a Jew in exile does not offer sacrifices, guard purities, or (outside the Land) tithe. The mechanism is supersession by selection: once the Rif became the through-studied halakhic spine - and the Rosh and the Tur built directly on it - the practical curriculum aligned to what the Rif kept, and the material he cut lost the recopying demand that keeps a text alive. The digest thus both records and enacts a triage. Prediction restated: measured against the Bavli it digests, the Rif's coverage collapses to the practically-applicable tractates - near-total for the used parts of Moed, Nashim and Nezikin, near-zero for Kodashim, Tohorot and non-Berakhot Zeraim - so the Rif reproduces well under half of the Bavli's daf-extent, and the omitted orders map precisely onto the same tractates that lost their independent base commentaries.
Prediction clause (verbatim)
Prediction: comparing the Rif's coverage to the Babylonian Talmud tractate by tractate in Sefaria, the Rif will carry text for under 45% of the Bavli's daf-extent (a coverage share < 0.45), with coverage near zero (< 0.1) for the orders Kodashim and Tohorot and for Zeraim excluding Berakhot, and near-complete for the practically-applied tractates of Moed, Nashim and Nezikin - primary clause: the < 0.45 overall Rif-to-Bavli daf-coverage share; the verdict follows it. The test voids for coverage if Sefaria's Rif is not mapped to Bavli daf references.
Kill-dataset (verbatim)
Kill: Sefaria's open Rif (Hilchot HaRif / Sefer ha-Halachot) keyed against the Babylonian Talmud daf structure - compute the fraction of Bavli daf-extent the Rif reproduces, per tractate and per order, with the Vilna Rif pagination as the control.
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
At tractate level the omission map is textbook - every survey states that the Rif covers Berakhot, Moed, Nashim, Nezikin, Hullin and the Halakhot Ketannot and drops the rest of Kodashim, Tohorot and Zeraim as non-applicable - so that half of the claim is already in print (Elon; Ta-Shma). But the primary clause is the overall daf-extent fraction (< 0.45), which turns on the within-tractate daf-presence of a digest that skips dialectic and aggadah unevenly; no daf-coverage tabulation of the Rif exists, and honest estimates straddle the threshold (covered tractates hold roughly 0.6-0.67 of Bavli daf-extent, times an unmeasured within-tractate presence). Genuine new tabulation with an uncertain outcome; note also that the Rif's full Hullin makes the packet's < 0.1 Kodashim sub-clause doubtful.
