The archipelago archive effect

Status: No prior located

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).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

The surviving Swahili manuscript record concentrates spectacularly in a few northern localities — above all the Lamu archipelago — although pre-1500 epigraphy shows literate settlement along three thousand kilometres of coast. This conjecture claims the corpus geography is an artifact of family-archive continuity, not a map of where writing happened: manuscripts survive where patrician households persisted undisrupted into the collecting era, and the southern and mainland blank is jointly real loss (destruction and town abandonment) and cataloguing gap (uncollected private holdings), rather than evidence of a mute south. Structurally, the medieval inscription map is the better production map, and the measurable MISMATCH between it and the manuscript map is precisely the size of the archive effect. If it holds, provenance-blind use of the manuscript corpus as a map of Swahili literary culture is invalid, and the southern gap becomes an estimable quantity with a search agenda attached.

Prediction clause (verbatim)

Primary clause: the geographic concentration of provenanced items in the SOAS database (a Gini or Herfindahl index across coastal settlements) exceeds the concentration of known pre-1500 literate settlements (inscription-bearing sites) by an index ratio of at least 2, with the northern archipelago's manuscript share exceeding its epigraphic share several-fold. Killed if manuscript provenance tracks the epigraphic settlement map roughly proportionally — survival as a fair sample of medieval literacy's geography.

Kill-dataset (verbatim)

SOAS Swahili Manuscripts Database — provenance and place-of-collection records.

Nobody has run this test. The kill-data is named above. If you can run it — or you know the paper that already settles it — claim the kill or submit the prior. Kills and priors are credited here, by name, as they come in.

Novelty / leakage triage

no prior formulation located (search dated 2026-07-10)

The northern/Lamu-centred provenance of the surviving Swahili manuscript record is a known fact, but the standard reading attributes it to northern literary preeminence; no located work argues the concentration is a family-archive-continuity artifact measurable as a mismatch against the pre-1500 epigraphic settlement map. Swahili manuscript-provenance statistics are a thin and unevenly accessible literature — this verdict records low locatability, not proven novelty.
