Astronomical tables
Kill-instrument — a dataset that can test conjecturesDISHAS, zij corpora, computus tables, horoscope recomputation, star catalogues, astrolabe/dial corpora.
Synopsis
LLM-authored synopsis Not an article May be staleAstronomy left one of the pre-print world's most rigorously checkable records, because the sky itself supplies an independent, calculable answer: DISHAS's database of historical astronomical instruments, zij tables (the Islamic-world genre of astronomical handbook), Easter-dating computus tables, recomputed medieval horoscopes, star catalogues, and corpora of surviving astrolabes and sundials.
Because a historical astronomical claim can be checked against modern astronomical calculation, this is one of the few instruments that supplies an external, non-textual ground truth. Astrolabe product lines and The gear module lineage both treat physical instruments -- astrolabes, geared calculating devices -- as manufactured product lines with their own lineage, testable the way any technology's evolution is. Horoscope stemmatics recomputes historical horoscopes to build a family tree of which astrological calculations copied which, and Sundial misfits looks for sundials whose errors reveal how their makers actually worked, rather than the geometry they intended.
Interpretive synthesis over gathered records only. It creates no article, evidence, inferon, source, or estimate.
