Finished on Friday
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)
Finished on Friday. This connects the colophon's weekday with devotional time-keeping in the workshop. Completion of a copy was an event, and the khatma carried blessing; a scribe nearing the end of the final quire could steer the finish to a blessed day, and had reason to when the book itself was sacred. If completion was steerable, the weekday distribution in colophons should be non-uniform with a Friday peak, and the steering should be strongest for Qurʾans, prayer books, and hadith, weakest for grammar, medicine, and commercial jobs, giving a measurable piety gradient running straight through the copying trade.
Prediction clause (verbatim)
Among colophons recording a weekday, Friday's share is at least 1.7 times the uniform expectation (at least 24.5% against 14.3%). Primary clause: the Friday share at or above 1.7x uniform; the verdict follows it. Secondary: the Friday excess for Qurʾans and devotional works is at least double the Friday excess for grammar, medicine, and secular poetry.
Kill-dataset (verbatim)
Kill: FIHRIST colophon transcriptions and the FiMMOD corpus (Fichier des manuscrits moyen-orientaux datés), which record complete colophon dates including weekdays.
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. Kills and priors 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
Colophon scholarship already observes that completion was often planned for a Friday, so the direction is anticipated qualitatively, but the quantified Friday share (>=1.7x uniform) and the piety gradient across genres have not been measured.
