Old shaykhs, young ears

Claim (verbatim)

Old shaykhs, young ears. This connects the market for isnad elevation (ʿuluww) with the demography of audition sessions. Families brought small children to auditions to mint transmitters whose chains would be enviably short seventy years later; that custom is known. The sharpening: child-bringing was priced arbitrage, so its intensity should track the expected scarcity value of the link, which is the age of the presiding transmitter. A session before a nonagenarian musnid is a closing window and worth dragging a toddler across town for; a session before a forty-year-old is not. The child share of the audience is therefore a market read on the shaykh's remaining lifespan.

Prediction clause (verbatim)

In dated audition certificates, sessions whose presiding musmiʿ was aged 70 or older (ages recovered from biographical dictionaries) show at least 1.5 times the share of attendees marked with child-attendance formulas (hadara and its variants, as against samiʿa) compared with sessions before shaykhs under 50. Primary clause: the 1.5x-or-greater child-share ratio between old-shaykh and young-shaykh sessions; the verdict follows it.

Kill-dataset (verbatim)

Kill: the Damascene audition certificates in Muʿjam al-samaʿat al-Dimashqiyya (Leder, al-Sawwas, and al-Sagharji), cross-dated against death dates in al-Dhahabi's Taʾrikh al-Islam in the OpenITI corpus.

Novelty / leakage triage

provisional — model-triaged, shepherd review pending

A provisional first pass authored by the model (Opus), not yet confirmed by the shepherd. It carries the same dated-search requirements as an authoritative verdict but is excluded from every headline figure and cannot underwrite a prediction until a shepherd confirms it. Provisional reading: Adjacent (closely related prior work exists).

Both halves are established: ʿuluww al-isnad (a chain with few intermediaries) was actively prized, and the practice of bringing infants and small children to audition sessions -- so their eventual chains would be enviably short -- is a documented feature of the mature hadith-transmission culture (Davidson, Carrying on the Tradition). Not located: the item's priced-arbitrage gradient -- child-attendance formulas (hadara etc., vs samiʿa) running >=1.5x more frequent in sessions before a musmiʿ aged 70+ than before one under 50, ages recovered from the biographical dictionaries. The child-audition custom is known; treating child-share as a market read on the shaykh's remaining lifespan, and measuring it against the Damascene certificates cross-dated to al-Dhahabi, is the unrun operationalization.
