Provincial Accents in Cotton
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 Inka empire was barely a century old at contact, stitched over far older Andean polities, and cord record-keeping demonstrably predates the Inka. The conjecture: catalogued khipus preserve regional accents — provenance-linked conventions of color usage, ply and knot direction, and cord spacing — strong enough that a classifier can assign a khipu to its region from structure alone, against the standard picture of a single imperially standardized recording system. The mechanism is training and inheritance: cord-keepers learned locally and carried pre-Inka habits forward, while the empire standardized only what had to interoperate — the decimal accounting layer — and left the rest dialectal, exactly as empires treat spoken language. If the conjecture holds, the khipu corpus becomes a map of information-administrative provinces, and the layered history of Andean record-keeping becomes legible without deciphering anything.
Prediction clause (verbatim)
Using provenanced khipus, train a cross-validated classifier on structural features (color inventory and combinations, ply and knot-direction rates, cord spacing). Primary clause (the verdict follows it): regional assignment accuracy is at least twice the majority-class base rate across at least 3 regions. Secondary clause: the discriminating features exclude the decimal knot grammar itself, which should be pan-regional; if the decimal layer is what varies, the standardization model inverts and the conjecture as posed is dead.
Kill-dataset (verbatim)
Open Khipu Repository (OKR): provenanced khipus with structural feature records supply the training and test data for the regional classifier.

Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Regional/functional variation in khipu conventions (color, ply/knot direction, spacing) and provenanced reference sites (Inkawasi, Pachacamac, Laguna de los Cóndores) are documented, and researchers explicitly propose testing spatial distributions of these features — but a cross-validated regional classifier trained on non-decimal structural features (excluding the pan-regional decimal grammar) has not been run.
