The tarjama looks upstream

Claim (verbatim)

The tarjama looks upstream. This connects the function of the tabaqat genre with a measurable network asymmetry. A biographical notice certifies credentials: it names the subject's teachers because his authority flows down from them, while his students are the future's business and someone else's entry. If the genre is a credentialing instrument rather than a memorial one, the citation network it encodes should be systematically lopsided, with teacher-mentions dwarfing student-mentions inside each entry, and the lopsidedness should be greatest where credentialing pressure is highest, among the hadith folk, and mildest among poets and litterateurs, whose standing came from output rather than from chains.

Prediction clause (verbatim)

Building a directed name-mention network from a large biographical dictionary, the mean count of teacher-mentions per entry (akhadha ʿan, samiʿa min, rawa ʿan formulas) exceeds the mean count of student-mentions (rawa ʿanhu, akhadha ʿanhu constructions naming the subject as source) by a factor of at least 2. Primary clause: the 2x-or-greater teacher-to-student mention ratio; the verdict follows it. Secondary: the ratio for hadith scholars exceeds the ratio for poets and udabaʾ in the same dictionary.

Kill-dataset (verbatim)

Kill: OpenITI machine-readable texts of al-Dhahabi's Siyar Aʿlam al-Nubalaʾ and al-Safadi's al-Wafi bi-l-Wafayat, with transmission formulas extracted by pattern matching.

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).

That the tabaqa is a credentialing notice that names a subject's teachers (authority flows down from them) far more than his students is a recognized character of the genre, and directed name-mention networks are now actually being built from these dictionaries (the 'Building a Digital Tabaqat' work; social-network analysis of narrator chains). Not located: the item's specific in-entry asymmetry as an executed count -- mean teacher-mentions (akhadha ʿan, samiʿa min, rawa ʿan) exceeding mean student-mentions by >=2x across a large dictionary, with the ratio higher for hadith folk than for poets and udabaʾ. Established genre feature and available method; the specific measured ratio and the hadith-vs-poets contrast are unrun.
