Provincial Accents in Cotton

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 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.

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.

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.
