Undelivered mail is a network sample
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)
The Sogdian Ancient Letters of c. 313 CE — merchant mail abandoned in a watchtower near Dunhuang — are usually read as a lucky window. Join them instead to a statistician's commonplace: lost mail is a sample of a mail stream, and a sample implies a population with structure. If the Sogdian colonies from Samarkand to China ran a working relay of commercial correspondence, the surviving scatter of Sogdian letters across sites should carry the fingerprints of a taught system — shared openings, shared address conventions, relay-node geography — rather than one-off idiosyncratic literacy, because merchants standardize whatever apprentices must learn, and a diaspora that moves silk on credit must move information on formula. This is a structural claim about a mostly lost circuit, tested on its surviving edge. If it holds, the Sogdian network stops being an anecdote of a few letters and becomes a measurable institution with schools behind it.
Prediction clause (verbatim)
Pooling Sogdian secular letters and epistolary fragments from Dunhuang and Turfan, at least 80% of items preserving an opening will share one formulaic greeting-and-blessing skeleton across sites and centuries. Primary clause: the 80% shared-skeleton rate; the verdict follows it. Secondary clause: mapped sender and recipient indications form a chain topology along the corridor, with intermediate oases appearing as both origins and destinations, rather than a single-centre star on Samarkand.
Kill-dataset (verbatim)
IDP records and images of Sogdian secular letters from Dunhuang (including the Ancient Letters) together with the Sogdian epistolary fragments in the Digitales Turfan-Archiv.

On Inferpedia
This conjecture is linked to the following pages on Inferpedia, an encyclopedia of the missing — working atlas pages, some still early scaffolding.
Provenance
Run: Fresh agent generation · model: claude-fable-5
Generated blind in a single Write by a fresh instance with no file reads, web access, or database queries; all context was inline in the launching prompt.
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Benkato's Studies on the Sogdian Epistolary Tradition shows epistolary formulae were maintained across centuries and far from Sogdiana, strongly anticipating the taught-system mechanism; the 80% shared-skeleton rate pooled across sites and the chain-topology mapping remain un-run.
