The third history the fourth one killed
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 Dongguan Han ji (東觀漢記, Dongguan Han ji), compiled at the imperial Dongguan through the second century, was once canonical: with the Shiji and Hanshu it formed the San shi (三史, Three Histories) that Tang candidates studied. Then Fan Ye's Hou Hanshu (范曄 後漢書, mid-fifth century) covered the same Eastern Han more elegantly, and the older history stopped being copied, decaying to fragments until Qing editors reassembled a partial text from the Yongle dadian (永樂大典) and the encyclopedias. The mechanism is pure supersession: when two books cover identical ground, the one judged inferior loses its classroom and its copyists, and the loss is datable by watching the citation traffic switch. A Northern-Song encyclopedia, compiling a century of received scholarship, should already show the switch complete - quoting the victor lavishly and the superseded history only as a residue. Prediction restated: in the Taiping yulan the Hou Hanshu is cited at least eight times as often as the Dongguan Han ji, the takeover essentially finished two centuries before the older history finished disintegrating. Supersession, unlike catastrophe, does not burn a book; it stops copying it, and the citation ledger records the exact moment the readers changed sides.
Prediction clause (verbatim)
Prediction: counting attributed citations of the Hou Hanshu (後漢書) versus the Dongguan Han ji (東觀漢記) in the Taiping yulan (太平御覽, 983), the Hou Hanshu will outnumber the Dongguan Han ji by at least eight to one (primary clause: the >=8:1 Hou-Hanshu-over-Dongguan attributed-citation ratio in the Taiping yulan; the verdict follows it); citations are matched on normalized title forms to guard against abbreviation, and the test voids for coverage if the two titles together draw fewer than 100 attributed citations.
Kill-dataset (verbatim)
Kill: the Chinese Text Project (ctext.org) full text of the Taiping yulan (太平御覽), string-matching the two histories' attributed citation titles and comparing their instance counts.
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, East Asia instrument-anchored wave against ctext/CBETA/SAT/Kanseki: every kill names a specific open corpus and a countable operation (loss-annotation counts, catalogue-to-survival ratios, cited-title censuses, citation-geometric overlap, attribution-growth), thresholds far from 1 with coverage guards; disjoint from the 2026-07-08 East Asia wave (different works and operations - Suishu/Yiwenzhi/leishu reused only as instruments under new loss-census operations, flagged) and from the 2026-07-16 India wave, which already owns the Kaiyuan lu missing-books register (pivoted here to An Shigao attribution inflation); Samguk Sagi (not the Yusa used elsewhere) and Fuyo wakashu (Kokka Taikan instrument shared with a Man'yoshu item, seam distinct); dropped the Yongle dadian survival-rate candidate as overlapping the prior wave's print-threshold item. Numbers flagged MODERATE where counts vary are kept out of the load-bearing primary clauses.
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
The supersession of the Dongguan Han ji by Fan Ye's Hou Hanshu is textbook, and the older history's reconstruction from leishu including the Taiping yulan is the basis of Wu Shuping's standard 東觀漢記校注. But the primary clause is a specific in-corpus citation ratio — Hou Hanshu outnumbering Dongguan Han ji >=8:1 among attributed TPYL citations — and no published work reports that count. Materials in print (both histories' citation traffic is recoverable), the ratio un-run: adjacent. Indeed the Dongguan Han ji was partly rebuilt from its TPYL citations, so its citation count there is non-trivial and the ratio genuinely needs measuring.
