The sherd sets the line
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)
A potsherd is a fixed, curved, often small writing surface, and that geometry should discipline the text written on it: line lengths truncated at sherd width, and — the sharper effect — abbreviation and symbol rates rising to squeeze standard formulas into non-standard space. Papyrus imposes no such constraint, so with genre held constant, receipts on ostraca should be measurably more compressed than the same receipt formulas on papyrus. The Duke Databank encodes abbreviations explicitly, so the medium's pressure on notation is directly countable. If it holds, part of what palaeographers read as documentary informality on ostraca is the physics of the sherd, and abbreviation systems look like adaptations to surface scarcity rather than scribal laziness.
Prediction clause (verbatim)
In papyri.info tax receipts, abbreviation markup per 100 words is at least 1.5 times higher on ostraca than on papyrus for the same receipt genres and period bands. Primary clause: that ratio, tested as a distribution difference across the two materials — a statistical test.
Kill-dataset (verbatim)
papyri.info (DDbDP expansion/abbreviation markup with material metadata).
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.

Run: Fresh agent generation · model: claude-fable-5
Generated blind by claude-fable-5 in a single Write from the inline prompt alone, with no file reads, web access, or database queries.
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Abbreviation density on ostraca receipts is documented, but the standard explanation is mass-production of repetitive formulas, not surface geometry; the material-controlled comparison (same genre on ostraca vs papyrus) that would separate the two is un-run.
