The binder's knife prefers big game
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).
“Anticipated in print” means the direction of this claim already appears in scholarship, while this exact test has never been run — it records prior art, not proof; nothing here counts as supported or falsified until a registered resolution says so.
Claim (verbatim)
Binders wanted large, stiff sheets of parchment for covers, spine-linings, and pastedowns, so the recycling channel did not sample the Hebrew book population evenly: a large-format Bible or Talmud yields useful sheets, a pocket prayer book yields little worth the knife. The conjecture is that the binding-fragment corpus is a size-biased sample of destroyed books, and the bias is estimable: fragment dimensions and reconstructed layouts imply original formats skewed heavily toward large volumes relative to the format distribution of intact survivors, and correcting for this selection materially changes the estimated composition of the lost population, restoring the small everyday book to a dominant share. The destroyed library, properly weighted, looks less like a shelf of great codices and more like a drift of cheap little books that vanished without even leaving scrap. If this holds, every genre-share estimate built naively on fragment counts must be reweighted by format.
Prediction clause (verbatim)
Primary clause: reconstructed original formats of Books Within Books fragments show large-format volumes at more than twice their share among intact dated Hebrew codices of matching region and period. Secondary clause: inverse-probability weighting by format shifts at least one major genre's estimated share of the destroyed population by five percentage points or more. The verdict follows the primary format-skew clause.

On Inferpedia
This conjecture is linked to the following pages on Inferpedia, an encyclopedia of the missing — working atlas pages, some still early scaffolding.
Provenance
Run: Fresh agent generation · model: claude-fable-5
Generated in a single blind Write with no reads, web access, or database queries; this is a relaunch after the prior W19 attempt was stopped mid-run.
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
That binders preferred large stiff parchment sheets is noted in European Genizah scholarship, but no size-bias estimation of reconstructed fragment formats against SfarData's intact-format baseline, nor inverse-probability reweighting of the destroyed population, has been run.
