The phantom tablets in the mailbag
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)
Cuneiform letters are unusually self-referential about writing itself: they mention tablets sent, tablets requested, tablets to be copied, tablets awaited. Two corpora make this countable. The Correspondence of the Kings of Ur (CKU, ed. Piotr Michalowski 2011) collects Ur III royal-administrative letters, and the Neo-Assyrian scholars' letters to Esarhaddon and Assurbanipal (SAA 10, ed. Simo Parpola) are thick with 'send me the tablet,' 'I have written it out,' 'the tablet is being copied.' Each mentioned tablet is an attestation that a specific document once existed, and the vast majority of those specific mentioned tablets are not among recovered holdings. The letters are, in effect, a census of missing clay taken by the people who handled it. The mechanism is that correspondence indexes the working document-traffic of an administration, most of which - being ordinary working tablets - was never preserved or has not been dug.
Prediction clause (verbatim)
Prediction: text-mine CKU and SAA 10 for tablet-transmission references (send, request, copy, or collate of a named or specified tablet); at least 60 percent of the individually-specifiable tablets referenced in these letters cannot be matched to any recovered tablet (primary clause: the phantom-tablet fraction >= 0.60). Disambiguation: count only references to a specifiable document - a named composition, a specified report, a numbered tablet - not generic 'writing'; a reference is 'matched' only if a recovered tablet plausibly answers its description and date. Coverage guard: matching is inherently permissive, so report the phantom fraction as a lower bound, resolving every doubtful match IN FAVOUR of survival, which makes the finding conservative.
Kill-dataset (verbatim)
Kill (not yet built): CKU (ETCSL/ORACC) and SAA 10 (ORACC/SAAo) are fully published and searchable, but the tablet-reference census and the match-to-holdings are an analytical pass to be run, not an existing table. Real corpora; the operation is defined but must be executed.
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, cuneiform instrument-anchored wave against CDLI (including the in-house catalogue copy), ORACC, BDTNS, and Archibab: every Kill names a specific open corpus and a countable operation (catalogue-incipit vs recovered census, series colophon N-of-M completeness arithmetic, un-enrichment residue, directional letter-asymmetry, dated-histogram discontinuity, lexical-vs-documentary attestation gap, intake-vs-holdings, curricular copy-frequency, godlist-vs-cult, chronology-vs-attestation, forgery-by-genre, provenance-null-by-genre, letter tablet-census, and genre/period composition shares). Disjoint by construction from the 30 cuneiform conjectures of wave w22 (grep-checked per key name and per instrument-operation). In-house CDLI copy = 126,000 rows (about 30 percent of CDLI's 421,501), harvested 2026-07-04; exact in-house aggregates cited in the runnable-this-week items: genre-blank 10.4 percent, language-undetermined 14.3 percent, provenience-null 11.9 percent, flagged fakes 160 (0.127 percent), Administrative 70.9 percent, Ur III 47.4 percent, Old-Babylonian:Middle-Babylonian dated ratio about 8. Six items resolve THIS WEEK against the in-house copy (ordinals 3, 5, 11-partial, 12, 13, 15); two carry an honest 'Kill (not yet built)' where the cross-instrument join is real in sources but not yet a dataset (ordinals 6, 7, 14).
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Tablet-traffic self-reference in the scholars' letters is a documented theme - Parpola's SAA 10 corpus is the standard witness and Robson's knowledge-networks study discusses the requesting and copying of tablets - but the proposed reference census with match-to-holdings has not been executed for either corpus; the kill itself concedes the pass must be run. Caveat: CKU survives as Old Babylonian school copies whose documentary authenticity Michalowski's edition treats as debated, which weakens the 'census taken by the handlers' premise for the Ur III half.
