The quinion follows the ream
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)
The quinion follows the ream. This connects Arabic quire structure with the economics of the paper trade. Arabic codices characteristically use quinions (five-bifolium gatherings) where Greek, Syriac, and Latin books use quaternions, and the difference is usually filed under scribal custom. The conjecture: the quinion is a market artifact, not a cultural taste. Warraqs bought paper in fixed-count dasta and ream units whose divisors favored five-sheet folding batches, and fewer sewing stations per volume cut binding labor on a cheap, abundant support; parchment, cut piecemeal from hides, kept the older quaternion logic. If so, quire structure should track the writing support within one culture, not the culture across supports.
Prediction clause (verbatim)
Among Arabic manuscripts dated or datable before 600 AH with recorded collation, paper codices are quinion-dominant (at least 60% of regular gatherings are quinions) while parchment codices from the same regions and centuries show a quinion share at least 25 percentage points lower. Primary clause: the 25-point-or-greater quinion-share gap between paper and parchment codices; the verdict follows it. Secondary: Maghribi parchment codices, where parchment persisted longest, show the lowest quinion share of any regional group.
Kill-dataset (verbatim)
Kill: FIHRIST collation and support fields for early dated Arabic manuscripts in UK collections, supplemented by vHMML codicological metadata for Middle Eastern collections.

Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Déroche's Islamic Codicology documents quinion dominance in the Arabic tradition — including in early parchment Qurʾans, which complicates the premise — but the economic explanation via ream/dasta divisors and a paper-versus-parchment quire-share comparison within one culture has not been run.
