AI-generated conjecture · below the evidence/publication boundary

The model book is colour-blind

Status: Anticipated · untested

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).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

The model book is colour-blind. Pattern sheets travelled as outline drawings with colour given verbally — the Göttingen Model Book literally writes out its recipes — while copying from a finished exemplar transmits paint by eye but forces a freehand redraw. Two transmission channels, opposite bandwidths: model-book descent should show tight geometry with a loose palette, exemplar descent a tight palette with loose geometry. The variance signature identifies the channel even where no model book survives.

Prediction clause (verbatim)

Primary clause (the verdict follows it): the sign of the difference between shape fidelity and colour fidelity is positive for motif groups scholarship ties to pattern-sheet transmission (the Göttingen Model Book acanthus group) and negative for direct exemplar copies among coloured witnesses of the Utrecht Psalter recension (the Eadwine Psalter against Paris BnF lat. 8846), measured on matched motif pairs as outline correlation versus hue correlation in calibrated digitizations. Secondary clause: in the model-book arm, shape correlation exceeds colour correlation by at least 0.2.

Kill-dataset (verbatim)

Kill: the fully digitized Utrecht Psalter (Utrecht University), British Library Harley 603, the Eadwine Psalter (Trinity College Cambridge), BnF lat. 8846 on Gallica, and the digitized Göttingen Model Book with its associated decorated volumes.

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); 278-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_w05_prompt_20260708.txt. Wave W05 of docs/GOAL_CONJECTURES_1001_CAMPAIGN_20260708.md. Novelty unverified by construction. A platform output-limit resume occurred before the single Write; no additional tool calls or information ingress occurred.

Novelty / leakage triage

anticipated in the literature — this exact test has never been run

The two transmission channels are documented — the Göttingen Model Book transmits outline plus verbal colour recipes, and the Utrecht Psalter recension exemplifies direct exemplar copying — but the opposed shape-versus-colour variance signature has not been measured.
