The colophon dies first
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)
Everything we know statistically about dated Hebrew manuscripts flows through colophons, and colophons live in the most dangerous real estate in a codex: the final leaves, first to be lost to wear, damp, and detached quires. Dated manuscripts are therefore not a random sample of survivors but a sample of well-preserved survivors, and preservation quality correlates with age, use-intensity, and format. The conjecture is that this end-loss filter measurably distorts the shape of Hebrew book history: heavily used genres and older books are systematically under-dated relative to their true share of survivors, so production curves built from the dated record alone understate early and everyday production. The bias is estimable, because the digitized corpus lets one count undated manuscripts whose final leaves are demonstrably missing. If this holds, the best-dated manuscript population on earth needs — and can be given — its own survival correction.
Prediction clause (verbatim)
Primary clause: in a systematic sample of digitized Hebrew codices in Ktiv, the proportion lacking their original final leaves is significantly higher among undated manuscripts than among colophon-dated ones, and higher among liturgical books than in the corpus at large. Secondary clause: applying the implied correction raises the estimated pre-1300 share of surviving production by a measurable margin. The verdict follows the primary differential end-loss comparison.
Kill-dataset (verbatim)
Ktiv, whose digitized codices allow end-leaf completeness audits, joined against SfarData's dated population.
In the kill-dataset registry:
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.
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 colophons are disproportionately lost because final leaves are damaged is a standard qualitative caveat, but no differential end-leaf-completeness audit of dated versus undated codices in Ktiv, nor a resulting survival correction, has been published.
