The Sankore lag
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 Sankore lag. Technology-diffusion theory describes adoption lags that collapse as a transmission channel routinizes; this conjecture measures that lag curve in Timbuktu codicology. Between 1400 and 1600 the Sahara's intellectual bandwidth tripled: pilgrimage traffic, commercial caravan routes, and the rise of Sankore scholarship turned an occasional trickle of exemplars from the Islamic heartland into a regular supply line. The delay between a work's composition in the heartland and its first dated West African copy should therefore collapse across composition cohorts: from a median of a century and a half or more for works composed before 1300 down to sixty years or less for works of 1450-1550, declining monotonically cohort by cohort, with the hazard of first West African copying roughly doubling per century of composition date. Flat or rising lags — a desert whose bandwidth never improved — kill it.
Prediction clause (verbatim)
From dated colophons in the Timbuktu catalogues, the median composition-to-first-copy lag falls from >= 150 years for works composed before 1300 to <= 60 years for works composed 1450-1550, declining monotonically across composition cohorts, with the hazard of first West African copying roughly doubling per century of composition date; flat or rising lags kill it.
Kill-dataset (verbatim)
Kill: dated colophons in the IHERI-ABT (Ahmed Baba Institute) and Mamma Haidara catalogues, with composition dates from Brockelmann's Geschichte der arabischen Litteratur.
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 scholarship. Kills and prior scholarship are credited here, by name, as they come in.

Provenance
Run: Fresh agent generation · model: claude-fable-5
Generated by a fresh Fable-tier instance at maximum effort with generation-first blindness (no repo/web/DB access); titles-only knowledge of existing items, embedded in titles_supplied per the batch-2 lane rule; prompt pre-committed in docs/GOAL_CONJECTURES_BATCH3_20260705.md (b043140). Novelty unverified by construction. titles_supplied stripped to the committed sidecar conjecture_fresh_fablemax_batch3_titles_supplied_20260705.md at import (schema additionalProperties:false; relaxation queued).
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
The trans-Saharan book trade as a transmission network is the subject of a dedicated scholarly volume (Krätli & Lydon) and colophon dating data exists (HMML cataloguing); the composition-to-first-West-African-copy lag curve was not located, and the dossier surfaced a real confound (150-200-year recopying cycles from material decay) any resolution must address.
