The dry-season scriptorium
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)
Sahel life is metered by the rains: farming in the wet months, caravans, travel, and teaching in the dry. Copying a book needs stable paper, workable ink, daylight leisure, and often a borrowed exemplar newly arrived by caravan — all dry-season goods. This conjecture claims manuscript completion dates therefore cluster hard in the dry-season months: writing was seasonal labour synchronized with the caravan and agricultural calendar, and the clustering should be stronger for long works, which monopolize a season, than for short ones. Because colophons give Islamic lunar months that precess through the solar year, the corpus contains its own control: a genuinely solar-seasonal signal appears only after converting dates, and cannot be mimicked by fixed lunar-month piety such as a Ramadan effect. If it holds, the tempo of African book production was set by rainfall, and an agrarian work-calendar is recoverable from colophons alone.
Prediction clause (verbatim)
Primary clause: converting dated colophons in vHMML Sahel manuscripts to solar calendar dates, completion frequency in the November-April dry window exceeds uniform expectation significantly (Rayleigh or chi-square test on solar months), and this solar effect exceeds any fixed Islamic-month effect estimated on the unconverted dates. Killed if completions are uniform across the solar year, or the signal reduces entirely to fixed lunar months.
Kill-dataset (verbatim)

How this item is catalogued
Catalogue tags are curatorial metadata that make the conjecture findable. They are not findings, not a novelty verdict, and naming a source family is not a promise that the data exist or are accessible. Each dimension below says whether it was assigned, reviewed with none applying, uncertain, or not yet reviewed, and who recorded it.

Novelty / leakage triage
no prior formulation located (search dated 2026-07-10)
Colophon scholarship for Arabic and Sahel manuscripts records completion dates but no located study analyses their month-of-year distribution, seasonal clustering, or a lunar-to-solar conversion control. Given how little quantitative colophon work exists for the Sahel at all, this is a thin-field low-locatability verdict rather than a novelty demonstration.
