An index of the unsafe shelf
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 Bibliotheca reviews no Homer, no tragedy, no Aristophanes, essentially no Plato and no Aristotle - none of the texts the Byzantine classroom recopied every generation. Its 280 codices are prose, and mostly prose from off the syllabus: historians major and minor, heresiological dossiers, novels, lexica, acts of councils, medicine and science, with the ten Attic orators entering chiefly through biographical notices drawn from pseudo-Plutarch (codd. 259-268). N. G. Wilson (Scholars of Byzantium) reads the omissions as presumed knowledge: Tarasios had the school books already, so the Bibliotheca indexes the shelf beyond the curriculum. That reading has a countable consequence which converts the celebrated loss-rate into a calibrated statement about shelf stratification: even where reviewed works survive, they should sit far down the Pinakes witness distribution, because Photios was sampling precisely the stratum with no replication engine behind it. 'Half of Photios is lost' then measures not average Greek loss but the mortality of the unprotected shelf - while the school canon, with witness counts running into the hundreds, is the invisible control group he never bothered to review. The two strata should be separated not by degrees but by an order of magnitude, and the join of a ninth-century reading list to a twenty-first-century witness database is exactly the operation Pinakes makes possible.
Prediction clause (verbatim)
Prediction: among works reviewed in the Bibliotheca that survive independently, fewer than 15% will have 20 or more witnesses in Pinakes, whereas among a pinned school-prose control (the principal works of Herodotus, Thucydides, Xenophon, Plato, Isocrates, Demosthenes, Aristotle, Plutarch, Lucian, Aelius Aristides) more than half will exceed 20 witnesses (primary clause: the two-sided contrast, under 15% versus over 50% at the 20-witness line; the verdict follows it); disambiguation: witness counts are per work, not per author, using the in-house Pinakes extracts; the control set is pinned before counting; coverage guard: void if fewer than 60 reviewed works have resolvable Pinakes records.
Kill-dataset (verbatim)
Kill: the Bibliotheca's codex list (Henry's edition) joined to the in-house Pinakes works-by-witnesses extracts already used in past resolutions - a witness-count distribution comparison between the reviewed set and the school-prose control.
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.
Provenance
Run: Fresh agent generation · model: claude-fable-5
Fresh blind generation by claude-fable-5, 2026-07-17, Byzantine instrument-anchored wave against DBBE/Pinakes and the empire's self-indexing censuses (Photios' Bibliotheca, the Suda, the Excerpta Constantiniana): every kill names an open instrument and a countable operation (review-length-vs-survival quartiles, witness-count contrasts, condemned-partition survival ratios, title-list censuses, stemmatic agreement rates, collection-witness geometry, fragment-carrier attribution, book-block contiguity, earliest-witness histograms, double-notch production comparison, catena-only shares, calendar-gradient retention, per-book anthology retention, renewal-formula date lags, destroyed-carrier joins). Disjointness checked against the full corpus and all 2026-07-16/17 waves: the w11 Byzantine wave (35 items) owns the seal/PBW joins, DBBE patron-network/meter-rank/gender/disaster/debasement/gift operations, the 1204 deluxe-dedication survival discontinuity (w11-012) and post-1453 copying geography (w11-035) - the double-notch item here compares aggregate dated production rates instead; w11-028 owns seal-conditioned pre-metaphrastic retention - the Metaphrastes item here partitions by the Menologion's own calendar-density gradient (per steer, kept witness-geometric via Pinakes); fablemax-batch2-004 owns the Pinakes singleton/Chao1 census and batch3-004 the Pinakes-DBBE distribution collapse - the planned classical-vs-Byzantine witness-curve item was DROPPED for that ownership, replaced by earliest-witness-date geometry (the transliteration needle) which no item owns; the palimpsest lower-text-rate candidate was DROPPED (owned trio: w25-001 price barometer, w10-017 Sinai undertext languages, w11-027 sponsorship odds) with the Vat. gr. 73 palimpsest fact folded into the Excerpta single-witness item; Greek catena dismemberment is distinct from w02-013/019 (Pinakes polemic/council-premium operations) and w02-020 (Aquinas' Latin Catena aurea); DBBE operations here (renewal-formula chronology; destroyed-carrier join) collide with none of w07-018/019, w08-010/037, w09-039, w23-010..016, w26-008, minds-w01-011, minds-w02-006, batch2-005. Corpus 'Suda' hits outside this wave are 'Sudanic Africa' false positives; Photios, the Excerpta and the Palatine/Planudean comparison were wholly unowned. Honesty flags: MODERATE on the Photios quartile ratio, Suda title-survival shares and Planudean retention figures (thresholds cushioned in the safe direction); item 15 carries the wave's explicit Kill-(partly-not-yet-built) fallback (Pasini-catalogue back-collation). All predictions carry pinned disambiguation rules and coverage guards; thresholds far from 1 throughout.
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
The omissions and their presumed-knowledge reading are textbook (Wilson), and the school canon as replication engine is the frame of Reynolds & Wilson; but the two-strata witness contrast at the 20-witness line is not settled by print: the reviewed-survivor set contains heavily copied works (Herodotus cod. 60, Isocrates cod. 159, Lucian cod. 128, Aristides codd. 246-248, plus patristic heavyweights among the theological codices), so whether fewer than 15% clear 20 Pinakes witnesses is a genuinely open computation on the in-house extracts, while the school-prose control clause is safe. The stratification thesis leaks; the rate does not.
