Money is the last speaker of Sogdian
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).
“Anticipated in print” means the direction of this claim already appears in scholarship, while this exact test has never been run — it records prior art, not proof; nothing here counts as supported or falsified until a registered resolution says so.
Claim (verbatim)
Turgesh and other steppe coinages kept Sogdian legends long after courts and chanceries had moved on. Join numismatics to network economics: a coin's script must be readable across the whole trading network, so monetary script is locked in by network externality and outlives the state language by design — script on money tracks the commerce lingua franca while script on documents tracks the ruler. The corollary is testable on paper: the document trail should show not a sharp switch but a long commercial tail, with Sogdian persisting in secular and commercial documents at Turfan for generations after Uyghur became the majority secular language, because merchants, like coins, must interoperate. This is a structural claim about the trade zone beyond the oases, read off coins and killed on paper. If it holds, the death date of Sogdian splits into two honest numbers — chancery death and market death — perhaps a century apart.
Prediction clause (verbatim)
Primary clause (verdict-bearing): dated Sogdian secular documents at Turfan continue for at least 100 years after the crossover date at which Uyghur becomes the majority language of dated secular documents there, and the late Sogdian residue is disproportionately commercial (sales, loans, accounts) rather than official.
Kill-dataset (verbatim)
Digitales Turfan-Archiv dated secular documents in Sogdian and Uyghur, with IDP Sogdian records in addition.

Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Turgesh coinage with Sogdian legends and the late 'Turco-Sogdian' commercial documents of 9th-10th century Dunhuang (Sims-Williams & Hamilton) anticipate both halves — script lock-in on money and a long commercial tail of written Sogdian — but the two-clock formulation with a measured 100-year lag past the Uyghur crossover has not been run.
