Family chains hug the periphery
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)
Family chains hug the periphery. This connects transmission genealogy with urban market structure. In a metropole a student could shop among a hundred shaykhs; in a small town the household was the archive. Father-to-son transmission (ʿan abihi ʿan jaddihi) was therefore not primarily piety but a thin-market outcome: where the teaching market was deep, students diversified their chains across the best available masters, and where it was thin, they inherited. Family isnads should concentrate geographically at the edges of the scholarly world, and their share is an inverse index of local intellectual market depth.
Prediction clause (verbatim)
In machine-readable biographical dictionaries, the share of scholars whose recorded transmission includes a father-to-son link is at least 1.5 times higher among scholars based outside the five largest scholarly cities of their era (period-appropriate sets drawn from Baghdad, Damascus, Cairo, Nishapur, Cordoba, Istanbul) than among metropolitan scholars. Primary clause: the 1.5x-or-greater periphery-to-metropole ratio of family-link share; the verdict follows it. Secondary: the gradient steepens with distance from the nearest metropole, proxied by nisba toponyms.
Kill-dataset (verbatim)
Kill: al-Dhahabi's Taʾrikh al-Islam and Siyar Aʿlam al-Nubalaʾ in the OpenITI corpus, where kinship transmission formulas and toponymic nisbas are string-detectable at scale.
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.

Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Family isnads have been debated since Schacht and biographical dictionaries are now machine-readable and computationally analyzed (Romanov), but the thin-market hypothesis — father-son link share 1.5x higher outside the five largest scholarly cities — has not been tested.
