The archive keeps the incoming half
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)
What a genizah receives is what people had in hand when they cleared their papers: overwhelmingly letters they had received, not the ones they sent, which lay in other people's houses across the Mediterranean — mostly in towns with no surviving genizah. The Geniza correspondence corpus is therefore half an archive, systematically missing Fustat's own outgoing voice except where drafts and retained copies survived. The conjecture is that this asymmetry is measurable and invertible: the geographic distribution of senders versus addressees quantifies the inflow bias, and treating the preserved corpus as the receiving end of a two-way flow yields a defensible multiplier for the total letter traffic of the medieval Jewish Mediterranean — a circulation estimate with stated assumptions, not an impression. Drafts, identifiable by cancellations and blank addresses, provide an internal check on the outgoing remnant. If this holds, the Geniza converts from an anecdote-mine into a rate instrument for medieval communication.
Prediction clause (verbatim)
Primary clause: in the Princeton Geniza Project letter corpus, letters whose addressee location is Fustat or Cairo outnumber demonstrable outgoing items (retained copies and drafts written there for dispatch elsewhere) by at least five to one. Secondary clause: identified drafts show cancellation and correction rates several times the corpus norm, validating the classifier. The verdict follows the primary asymmetry count.
Kill-dataset (verbatim)

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 in a single blind Write with no reads, web access, or database queries; this is a relaunch after the prior W19 attempt was stopped mid-run.
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Goitein and later Geniza historians recognize the corpus preserves overwhelmingly letters received in Fustat (with drafts and retained copies as the outgoing remnant), but the quantified inflow-asymmetry count and its inversion into a Mediterranean letter-traffic multiplier have not been executed.
