The Arabic rate constant
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 Arabic rate constant. Joins autocatalytic reaction kinetics to the sociolinguistics of conquest: in Egypt's dated documentary papyri, the replacement of Greek and Coptic by Arabic behaved like a chemical substitution running with a nearly universal rate constant. The mechanism is autocatalytic — every office and notary that switched to Arabic raised the pressure on those it dealt with to switch, so once conversion began it fed on itself at a pace set by the feedback, not by local circumstance. Local circumstance instead set the onset: administrative centres close to the new Arab government tipped early, remote Upper Egyptian villages late. The conjecture therefore predicts that logistic curves fitted to the Arabic share of dated documents, region by region, will agree closely in steepness while their midpoints spread over more than a century, ordered by administrative centrality. Arabization differed across regions only in when it started, never in how fast it ran.
Prediction clause (verbatim)
For each Egyptian nome or region with >=150 dated documents between 550 and 1000 CE in papyri.info, fit a logistic curve to the Arabic share of dated documents per 25-year bin. The fitted steepness parameters will agree across regions within a factor of 2 (roughly 0.015-0.04 per year), while the fitted midpoints will spread over more than 100 years and will order by administrative centrality (Fustat and administrative centers first, Upper Egyptian villages last).
Kill-dataset (verbatim)
Kill: papyri.info documentary-papyri catalogue metadata (dates, places, languages). If regional logistic steepness varies by more than x3, or midpoints cluster within 50 years everywhere, the conjecture is dead.
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 reads, no searches, no DB queries); title list supplied at launch, titles only, no verdicts or dossiers seen; prompt pre-committed in docs/GOAL_CONJECTURES_BATCH2_20260705.md (7e55eb8). Novelty unverified by construction.
Novelty / leakage triage
no prior formulation located (search dated 2026-07-05)
Arabization of Egypt's documentary record is studied as qualitative periodization (Papaconstantinou; the 8th-century administrative shift; last dated Coptic document 1062/3), but no source was located fitting logistic curves to per-region language shares or comparing steepness/midpoints across regions. No prior formulation located (search dated 2026-07-05). In-house resolvable in principle (papyri.info languages, dates, places).
