The parasite outlives its host

Claim (verbatim)

The book the world cites as the Ta'rikh al-fattash is, on Mauro Nobili's demonstration, a nineteenth-century work: Nuh b. al-Tahir's rewriting of the seventeenth-century chronicle of Ibn al-Mukhtar, engineered so that a Songhay-era text would prophesy Ahmad Lobbo of Masina as the twelfth caliph. A state needing legitimacy did not commission a new chronicle; it colonized an old one, and the old one is now unreachable except through its parasite — the underlying Ibn al-Mukhtar chronicle survives nowhere independently and must be excavated from the very witnesses that carry the interpolation. The mechanism predicts a signature in the physical record: a textual tradition manufactured in the 1840s can have no old copies, and the propaganda instrument that broadcast the prophecy — Nuh b. al-Tahir's circular letter, the Risala — should out-survive the chronicle it advertised, because circulars are sent everywhere and chronicles sit in libraries. Prediction: no manuscript witness of the Fattash as edited by Houdas and Delafosse in 1913 will prove physically datable before 1800 by paper, hand, or colophon; copies of Nuh b. al-Tahir's Risala will outnumber copies of the chronicle itself; and no West African work composed before 1800 will quote the twelfth-caliph prophecy (primary clause: zero physically pre-1800 witnesses of the transmitted Fattash; the verdict follows it). Kill: the witness census in Nobili, Sultan, Caliph, and the Renewer of the Faith (Cambridge 2020), with the manuscripts behind the Houdas-Delafosse 1913 edition and the IHERI-AB and BnF (Bibliotheque nationale de France) catalogue records; the computation is a dated-witness tally for the chronicle against the Risala.

Novelty / leakage triage

already answered in the literature

This is Nobili's published finding: the transmitted Fattash is Nuh b. al-Tahir's nineteenth-century production (so no physically pre-1800 witness exists), the underlying Ibn al-Mukhtar chronicle survives only through the interpolated tradition, and the Risala is documented as one of West Africa's most widely reproduced texts, with dozens of copies far out-surviving the chronicle's few manuscripts. The conjecture restates the demonstration it cites as its own kill-source.
