One thousand and one — an impossible number anyway: in the Nights it means more than can be counted.

Specialist axes — method, instrument, provenance and more.

Known before? What the literature already knows about the claim.
Author Who posed it — the model, or a human.
Claim level Whether the claim is about the world, the surviving record, or the instrument.
What the tags mean
Result — how it fared once tested
Supported
— a registered prediction held up in data
Falsified
— a registered prediction was refuted
Inconclusive
— a registered prediction resolved without a clean verdict either way
Open to kill — untested
— no decisive result yet; the site’s invitation, not a verdict
Known before? — what prior scholarship already knows about the claim
Already answered
— the specific result is already published; the citation is on the item’s page
Anticipated
— the literature anticipates the direction, but this exact test has never been run
No prior located
— a dated search found no prior formulation (in thin fields this measures the literature’s thinness, not originality)
testable
— a quantitative prediction + kill-dataset is registered
Triage state
Shepherd-triaged
— an authoritative Fable-authored verdict; shown as the pills above and the only tier in the headline numbers
provisional — model-triaged, shepherd review pending
— an Opus-authored first pass, not yet shepherd-confirmed and excluded from every headline figure
awaiting prior-scholarship check — hunt open
— no triage yet; found a prior yourself? open it and weigh in

Byzantine pseudepigrapha should out-transmit the genuine works of the very fathers they impersonate, because forgery is demand-driven while authorship is occasion-driven. A pseudonymous homily was composed for an existing liturgical or catechetical market and was born into demand; a genuine work was…

the Hebrew translations of Judeo-Arabic philosophy were not diffusion but evacuation across a script frontier. As Arabic competence died out among the Jews of Christian Europe, translation was the only way the tradition could survive there at all, so the two versions'…

precision in Byzantine patristic citation was armor evolved in forgery arms races, not a scholarly virtue diffusing gradually. Wherever a doctrinal fight turned on accusations of forged or truncated proof-texts — the Monothelete crisis of the 640s, the iconoclast controversy resolved at…

writing a line-by-line commentary on an authority permanently converts a scholastic's citation channel to that authority from mediated to direct across his whole subsequent output. The commentary forces desk-level engagement with a complete exemplar; afterwards the master quotes from his own annotated…

the Mithila school's teaching monopoly in early Navya-Nyaya was a copying monopoly too, and it left a permanent physical signature. Works of the monopoly period should circulate almost exclusively in eastern scripts, while pre-monopoly Nyaya classics show pan-Indian script spread — institutional…

in the Guide of the Perplexed, naming is a safety and positioning policy, not a bibliography. Maimonides names authorities who are canonical and safely dead (Aristotle, al-Farabi) while his heaviest structural and textual dependence — the Avicennian analysis of necessary and possible…

the Paris condemnation of 1277 did not suppress the condemned theses, it anonymized them. Discussing a censured position under its author's name risked complicity, but the disputational machine could not run without its hardest objections, so masters kept the content and severed…

Indian philosophical curricula froze their opponent-set at the moment of the opponents' extinction. After Buddhism vanished from the subcontinent, Brahmanical works kept allotting Buddhists their full traditional share of polemical space for centuries, but the Buddhists engaged should be exclusively pre-extinction classics…

Chinese Buddhism ran two preservation channels with different physics. Scripture was reproduced by the lay merit economy — copying a sutra earned merit, copying a commentary did not — while scholastic literature survived through monastic cataloguing and canon compilation, which optimize completeness…

conciliar florilegia were canonization machines for individual works, not authors. A patristic work excerpted in the acta of an ecumenical council acquired a permanent copying premium over its author's other works, because the acta circulated empire-wide as authoritative proof-text maps and later…

the Catena aurea project (begun 1263) was a supply shock to Aquinas's citation economy. Compiling it built him a personal bank of newly translated Greek patristic excerpts, so afterwards his Greek-father citation volume should jump discontinuously across all genres of his writing…

Jain manuscript libraries preserved their opponents better than the opponents preserved themselves. Jain debate pedagogy required possession of rival texts, and the temple bhandaras had the institutional continuity that Brahmanical family-and-school transmission lacked; Brahmanical lines copied their own school, Jain libraries copied…

in the Sanskrit-Chinese transmission, terminological innovation was institutional, not chronological. State translation bureaus — staffed with bilingual philologists and armed with imperial authority — coined novel technical vocabulary freely, while lone translator-monks of the same decades reused familiar, often Daoist-flavored vocabulary, because…

Byzantine book epigrams stratify by the industrial structure of the copying that carried them. Liturgical and biblical books were produced by professional scribes reproducing a whole book-object, paratexts included, so their epigrams are mass-replicated formulae; philosophical manuscripts were copied by and for…

the Sentences-commentary genre drifted from pastoral coverage to speculative concentration on a measurable schedule. Disputational prestige, not curricular duty, set the incentives, and prestige lived in Book I's frontier problems — divine knowledge, future contingents, intension of forms — so between 1250…

the Tibetan imperial translation reform (the Mahavyutpatti and the sGra sbyor bam po gnyis pa decree, c. 814) shows that pre-print doctrinal standardization operated on vocabulary, not wording. When old translations were revised into the canonical versions, revisers should have overwhelmingly replaced…

in the Syriac schools, logic was not a discipline but a fixed propaedeutic block welded to theological training, so it was copied as a single curricular object for over a millennium. Porphyry's Eisagoge, the Categories, and De interpretatione should move together; the…

after about 1300 the working Aristotle of the arts faculties was a florilegium of exam-ready tags, not the translations. Oral disputation and examination rewarded fixed memorizable slogans, and once the popular auctoritates handbooks compiled them, the tag-list became the effective text —…

Coptic literacy was built by theology before administration touched it. The script community was created by scripture-reading and monastic institutions, and only once that community existed did Coptic seep into contracts, letters, and receipts — so documentary Coptic should lag literary and…

across the great translation movements, commentaries crossed the language frontier at far lower rates than base texts — except lemmatized commentaries that embed their base text, which crossed at near-base-text rates. Patrons commissioned usable, self-sufficient objects; a commentary without its base text…

This connects the diplomatics of multi-session audition certificates (samaʿat) with the incentive structure of certification. A samaʿ record for a long book lists who attended which sessions, and the legal and spiritual payoff was concentrated at the end: transmission rights vested at…

This connects Arabic quire structure with the economics of the paper trade. Arabic codices characteristically use quinions (five-bifolium gatherings) where Greek, Syriac, and Latin books use quaternions, and the difference is usually filed under scribal custom. The conjecture: the quinion is a…

This connects selective diacritical pointing in early Arabic documents with the sociology of correspondence. Pointing cost time and scribes applied it selectively; the question is what governed the selection. The conjecture: pointing density tracks social distance between writer and recipient. Between intimates,…

This connects hisba-literature complaints about copyists with measurable page economics. The market inspectors' manuals warn that copyists paid by the quire enlarge their script and widen spacing to inflate the folio count. If the warning tracked real practice rather than moralist boilerplate,…

This connects collation practice with the error spectrum of the resulting copies. Muqabala was typically performed aloud: one party reads the exemplar while the other follows the new copy. An acoustic channel catches what the ear can hear, namely omitted words, skipped…

This connects the well-known devaluation of the ijaza into a formality with the rhetoric of the document itself. As real audition decayed into blanket and even to-whom-it-may-concern licenses, the certificate lost evidentiary content; the conjecture is that the parchment compensated. Neither the…

This connects the market for isnad elevation (ʿuluww) with the demography of audition sessions. Families brought small children to auditions to mint transmitters whose chains would be enviably short seventy years later; that custom is known. The sharpening: child-bringing was priced arbitrage,…

This connects the one substantially surviving medieval Arabic institutional library catalogue with household book culture. An endowed library and a scholar's home solved different problems: the home held the curriculum, the matns, the working copies a man taught from and annotated; the…

This connects market law with the division of epistemic labor in the book trade. The hisba manuals regulate bakers' loaves and druggists' compounds, and they also cover the warraqs. The conjecture: their copyist clauses police only the material object, fading ink, badly…

This connects Ottoman probate evidence with the economics of a copyright-free book market. Where any text could be lawfully recopied by anyone, the work itself commanded no rent; scarcity lived entirely in the object, in the calligraphy, illumination, paper, and binding. The…

This connects the known takeover of the Islamic paper market by European mills with a datable moving boundary in the codicological record. Watermarked Italian paper displaced Oriental laid paper, but not everywhere at once: it should have swept as a front, arriving…
