Easter tables nobody computed
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)
The Ethiopian computus (Baḥrä ḥassab) fixes Easter through tables written in Geʽez numerals, themselves derived from Greek letters. If scribes actually recomputed the tables, copying errors would be caught and residual errors would be arithmetic — off by one within a cycle; if scribes copied the tables as pure visual objects, errors would be palaeographic — confusions between numerals of similar shape, regardless of arithmetic sense, and arithmetically impossible entries would ride along uncorrected for generations. This conjecture claims the second regime dominated: for most of its history the Ethiopian Easter table was transmitted calligraphically, not mathematically, calculation frozen into script. If so, one of Africa's longest continuous 'mathematical' traditions was in practice a scribal one, and the error structure of computus manuscripts becomes a direct measurement of how much numeracy stood behind the numbers.
Prediction clause (verbatim)
Primary clause: among variant and erroneous numeral readings in computus manuscripts transcribed in Beta maṣāḥǝft, shape-confusable numeral pairs account for at least twice as many errors as arithmetic-neighbour pairs; secondary clause: arithmetically impossible table entries recur uncorrected across descendant copies rather than being repaired. Killed if errors cluster on arithmetic neighbours or impossible entries are routinely fixed downstream — the signature of live recomputation.
Kill-dataset (verbatim)
Beta maṣāḥǝft — computus manuscript transcriptions and collations.
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.

Novelty / leakage triage
no prior formulation located (search dated 2026-07-10)
Neugebauer's Ethiopic Astronomy and Computus remains the standard treatment of the Bahra Hassab tradition, but no study of the error typology (shape-confusable versus arithmetic-neighbour numeral errors) in computus transmission was located. This is a very thin field — the verdict reflects low locatability of a small literature, not demonstrated novelty.
