The heirloom seal

Status: Already answered

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).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

The cylinder seal was Mesopotamia's signature: a carved stone rolled on clay to bind its named owner. Historians therefore use sealings as biographical evidence — this man was present, alive, in office. Durable-goods statistics suggest a trap: valuable durables outlive their first owners, and the conjecture is that seals did so routinely, showing a heavy-tailed lifespan distribution in the dated record with substantial mass beyond any plausible working career, because seals were inherited, delegated, and recut rather than retired. If it holds, a sealing identifies a household or office rather than a living individual, the dead-man-seals-a-tablet anomalies become expected statistics, and a layer of Ur III prosopography built on sealings needs a survivorship correction.

Prediction clause (verbatim)

Among Ur III seals attested on at least five dated tablets, at least 10 percent will show attestation spans (first to last dated impression) exceeding 35 years. Primary clause, which decides the verdict: the 35-year exceedance share among well-attested seals is at least 10 percent, against the under-3-percent expected if seals tracked single working careers. Secondary clause: in at least 3 percent of owner-linked cases, the seal is attested five or more years after the named owner's last personal appearance in any document.

Kill-dataset (verbatim)

BDTNS (seal-impression records linked to dated tablets) with the CDLI seals corpus for cross-checking legends.

Novelty / leakage triage

already answered in the literature

Searched Ur III seal use and inheritance. That seals were inherited, reused across generations, delegated (subordinates using superiors' seals), and recut — so a sealing marks a household/office rather than a living individual — is documented in the seal-practice literature; the conjecture's distribution statistics are new packaging on a published connection.
