The vase turns its back
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 vase turns its back. Maya polychrome cylinders pose a closed-loop composition problem, and workshop painters solved it the way a tailor does: by giving the garment a seam and placing it at the back. Because these vessels were presented and used along a principal viewing axis fixed by the palace scene's enthroned figure, the junction where the rollout design's two ends meet — the least resolved strip of the circumference — should sit diametrically opposite the principal figure: a planned blind spot, not an accident of drawing.
Prediction clause (verbatim)
In Kerr rollout photographs of single-scene court vases, define the seam as the vertical strip of lowest combined figural and glyphic density. Primary clause (the verdict follows it): the seam falls within the third of the circumference diametrically opposite the enthroned or principal figure in at least 65 percent of vases, against a 33 percent chance baseline. Secondary clause: seam strips carry filler elements (vegetation, stacked vessels, drapery, scene dividers) at at least twice their corpus-wide rate.
Kill-dataset (verbatim)
Kill: the Kerr Maya Vase Database (mayavase.com), whose published K-number rollout photographs allow seam location and principal-figure position to be scored directly on the open corpus, without new photography.
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
no prior located yet (provisional)
A provisional first pass authored by the model (Opus), not yet confirmed by the shepherd. It carries the same dated-search requirements as an authoritative verdict but is excluded from every headline figure and cannot underwrite a prediction until a shepherd confirms it.
[Independent blind re-audit 2026-07-08 (2nd pass, generator-independent), confidence low. Double-confirmed: both the provisional pass and this re-audit located no prior formulation of the specific operationalized claim. NOTE: low-confidence negative — an exhaustive search of specialist print scholarship was not achievable, so 'no prior located' is weaker here.] The Kerr rollout corpus is open, and workshop composition of Maya polychrome cylinders is studied (Reents-Budet, 'Painting the Maya Universe'; the notion of a principal/primary scene and enthroned figure is standard). But I located no study identifying a compositional 'seam' (the least-resolved vertical strip where the wrap-around design's two ends meet) and testing that it falls diametrically opposite the principal/enthroned figure in >=65% of single-scene court vases, with seam strips carrying filler at >=2x corpus rate. The closed-loop composition problem is understood; the specific seam-location-vs-principal-figure prediction, scored on Kerr rollouts, appears untested. Confidence low: art-historical claims are hard to search exhaustively and the negative could hide in a specialized ceramic-analysis publication.
