The tradition hangs on one date
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)
Written Swahili has almost no dated anchor before the eighteenth century, and its earliest fixed point is a translation: the Hamziya, a Swahili rendering of al-Būṣīrī's Arabic Hamziyya whose composition is dated 1652 (attributed to Sayyid Aidarus), while the oldest surviving dated Swahili manuscript is the 1728 copy of the Utendi wa Tambuka (Chuo cha Herkal). Two centuries of colophons and manuscripts do not precede these; they follow. The mechanism is coastal substrate loss compounded by a script-and-genre threshold: humid, insect-rich, salt-air conditions gave paper a short life, and the earliest Swahili writing that survives at all does so because a few prestige works were repeatedly recopied — so the tradition's documented depth rests on a mere handful of early dated points, and the pre-1650 written layer is inferential, reconstructed from later copies and from the Arabic models rather than attested in objects. Prediction: securely dated Swahili textual attestations before 1750 will number in the low single figures (with the 1652 Hamziya composition and the 1728 Utendi wa Tambuka manuscript among the very earliest), and no Swahili manuscript will be securely, internally datable before 1650 (primary clause: fewer than five securely dated pre-1750 Swahili attestations, none before 1650; the verdict follows it). Kill: Jan Knappert, Four Centuries of Swahili Verse (1979), with the manuscript descriptions of the earliest utendi (the SOAS Swahili manuscript collections and the Hichens materials) and the standard editions of the Hamziya and the Utendi wa Tambuka; the count is a dated-witness tally, no unified early-Swahili manuscript database yet existing.

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
already answered in the literature
The earliest fixed points of written Swahili are textbook. The standard literary histories give the 1652 Swahili Hamziya (after al-Būṣīrī's Hamziyya, attributed to Aidarus) as the earliest dated Swahili text and the 1728 Utendi wa Tambuka (dated 1141 AH; Chuo cha Herkal) as the oldest surviving dated Swahili manuscript, with nothing securely dated before. The primary clause — fewer than five securely dated pre-1750 attestations, none before 1650 — restates exactly this published account of the tradition's shallow documented depth, naming the very anchor points (Hamziya, Utendi wa Tambuka) that the standard editions already fix. This is a textbook philological fact, not an un-run test.
