The cutting-stock codex
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 cutting-stock codex. The cutting-stock problem of operations research — how to cut standard stock into pieces with minimal waste — meets codicology. This conjecture holds that parchment page sizes were not aesthetic free choices but near-optimal cuts of animal skins: a skin is a roughly fixed regional rectangle, and folding it in halves, quarters, eighths, and sixteenths is the waste-minimizing way to make leaves, so leaf dimensions should quantize at dyadic folds of regional skin sizes rather than vary continuously. Paper leaves, cut from standard mould sizes under a different production constraint, should cluster at different and sharper modes. Concretely, in thousands of dated European parchment codices the joint height-width distribution should be multimodal, with a solid majority of leaves within a few percent of a dyadic fold series of reconstructed regional skin sizes, implying material wastage under a fifth; a smooth unimodal parchment size distribution kills it.
Prediction clause (verbatim)
In >= 2,000 dated European parchment codices, the joint height-width distribution is multimodal with >= 60% of leaves within +/-6% of a dyadic fold series (1/2, 1/4, 1/8, 1/16) of reconstructed regional skin sizes, implying material wastage <= 18%; contemporary paper codices show mould-derived modes at distinct loci. A smooth unimodal parchment size distribution kills it.
Kill-dataset (verbatim)
Kill: leaf-dimension fields of e-codices and the Schoenberg Database of Manuscripts.
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 at maximum effort with generation-first blindness (no repo/web/DB access); titles-only knowledge of existing items, embedded in titles_supplied per the batch-2 lane rule; prompt pre-committed in docs/GOAL_CONJECTURES_BATCH3_20260705.md (b043140). Novelty unverified by construction. titles_supplied stripped to the committed sidecar conjecture_fresh_fablemax_batch3_titles_supplied_20260705.md at import (schema additionalProperties:false; relaxation queued).
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Kwakkel's dimension-economics program is the named close prior (353 manuscripts, offcut-reuse economics) and skin-to-folio yields are quantified (KBR), with cutting-stock OR mature since Kantorovich; the dyadic-fold quantization/multimodality test on leaf sizes was not located.
