The library shelves what homes don't
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).
“Anticipated in print” means the direction of this claim already appears in scholarship, while this exact test has never been run — it records prior art, not proof; nothing here counts as supported or falsified until a registered resolution says so.
Claim (verbatim)
The library shelves what homes don't. 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 endowment held what no individual could afford or justify owning, the multi-volume reference sets, the prestige compilations, the consultation literature. If so, the institutional and domestic strata of the book world were complementary rather than duplicative, and their title lists should be nearly disjoint even within one city and century.
Prediction clause (verbatim)
The Jaccard title-overlap between the 13th-century Ashrafiya library catalogue in Damascus (over two thousand entries) and published private book lists and estate inventories from Syria and Egypt of the 12th-15th centuries is at most 0.15. Primary clause: the Jaccard bound of 0.15; the verdict follows it. Secondary: multi-volume works are over-represented in the Ashrafiya relative to the private lists by at least a factor of 2.
Kill-dataset (verbatim)
Kill: the published edition of the Ashrafiya catalogue (Hirschler, Medieval Damascus: Plurality and Diversity in an Arabic Library, Edinburgh 2016) against published medieval private and estate book lists from Damascus and Cairo.

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
Generated by a fresh Fable-tier instance (claude-fable-5) at maximum effort with generation-first blindness (no repo reads, no web searches, no DB queries); 218-title list supplied at launch, titles only, no verdicts/dossiers seen; prompt pre-committed in docs/generated/conjectures_1001_wave_ledger.md and docs/generated/conjecture_fresh_fable_w03_prompt_20260708.txt. Wave W03 of docs/GOAL_CONJECTURES_1001_CAMPAIGN_20260708.md. Novelty unverified by construction.
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Hirschler's edition and study of the Ashrafiya catalogue (2,000+ entries) and Liebrenz's reconstruction of private Damascene collections provide both sides of the comparison, but a Jaccard title-overlap computation between institutional and domestic strata has not been performed.
