A chronicle with no first copy
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)
The Pate Chronicle, the dynastic history of the Nabahani rulers of Pate in the Lamu archipelago, is a foundational source for the northern Swahili coast — and it has no early manuscript. It exists only in several divergent recensions written down or dictated around 1890-1910 and in versions collected by early colonial-era compilers (C. H. Stigand, The Land of Zinj, 1913; and others), collated much later by Marina Tolmacheva (The Pate Chronicle, 1993). The mechanism is transmission through a late, partly oral bottleneck: a text repeatedly performed and recopied in a humid coastal climate that destroys paper leaves the modern record with no witness older than the moment outside collectors created demand for a written version, so what survives is a family of late, mutually disagreeing texts rather than a single archived chronicle — the divergence among the recensions is the fingerprint of oral-inflected transmission, not scribal copying of one exemplar. Prediction: across the independently collected Pate Chronicle recensions, no witness will be securely datable before circa 1880, and the recensions will disagree on dynastic sequence and regnal detail at a rate far above what stemmatic copying of a single written exemplar would produce — pairwise substantive divergence in the king-list exceeding a quarter of entries (primary clause: no pre-1880 witness together with greater-than-scribal divergence among recensions; the verdict follows it). Kill: Marina Tolmacheva, The Pate Chronicle (Michigan State University Press, 1993), collating the recensions, with Stigand's The Land of Zinj (1913) and the Pate texts in Freeman-Grenville, The East African Coast: Select Documents (1962); the divergence measure is a recension-collation count.

Provenance
Run: Fresh agent generation · model: claude-fable-5
Fresh blind generation by claude-fable-5, 2026-07-17, Sub-Saharan Africa wave 2, weighted by inferred textual production rather than survival, cataloguing, or digitization; every item grounded in real works, authors, chronicles, catalogues, and testimonia and in the real evidence of loss (colonial capture, single-copy transmission, translation-only corpora, Ajami catalogue-invisibility, substrate attrition, and manuscript populations inferred rather than counted), with no fabricated citations, and deliberately disjoint from the 2026-07-10 w16 Africa wave and the 2026-07-16 Africa/Americas wave. Nine candidates were dropped for duplication or a weak kill: the Kilwa Chronicle double-transmission (coin-audit already posed in breadth-africa-americas), the Ahmad Gragn fire age-profile and the Tarikh al-Fattash forged-layer (both already posed there), the Bamum/Njoya script life-cycle (already posed there), the generic Qasr Ibrim genre-proportion and a second Nubia item (w16 Nubia cluster), the Kano Chronicle stratigraphy (folded to avoid a third late-single-witness chronicle), a Futa Jallon Fula Ajami item (dropped to avoid Ajami over-weighting), and a Cape Arabic-Afrikaans item (dropped as too late for the premodern brief).
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Tolmacheva's edition collates the divergent Pate Chronicle recensions, and their late origin (dictated or written down c.1890-1910; Stigand 1913) is established — so the 'no witness before c.1880' half of the primary clause is close to a fact of the field. But the clause is a conjunction that also pins a divergence magnitude: pairwise substantive king-list disagreement exceeding a quarter of entries, above what single-exemplar copying would yield. Tolmacheva documents the divergence qualitatively but does not report it as a greater-than-25% collation rate, and no one has run that greater-than-scribal test as a number. The compound clause is not fully in print.
