The writ writes the charter

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)

Historians often read the rising count of English private charters as a gauge of the land market or of spreading literacy; this conjecture joins the charter-production curve instead to the menu of royal remedies. The claim is that ordinary people bought documentation the way people buy locks after a police force forms: each new legal device that made a document decisive — the possessory assizes from 1166, the statutory reshaping of conveyance around 1290 — produced a step in charter output, while the stretches between produced almost no residual growth. Chancery clerks and buyers behaved rationally: a charter is worth its parchment only when a court will act on it. If this holds, the medieval "documentary revolution" is punctuated legal history rather than gradual commercialization, and economic inferences drawn from smooth readings of charter counts are confounded.

Prediction clause (verbatim)

Primary clause: a change-point analysis of dated-and-datable charter counts per year in DEEDS across c. 1080-1330 locates its two largest structural breaks within ±15 years of 1166 and 1290. Secondary clause: between detected breaks, detrended per-year growth is statistically indistinguishable from zero, i.e., the series is closer to a step function than to an exponential.

Kill-dataset (verbatim)

DEEDS (the Documents of Early England Data Set), whose dated charter series at scale is exactly the required time series.

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

Clanchy's documentary-revolution thesis ties charter proliferation to royal legal remedies including the possessory assizes, but a formal change-point analysis of the DEEDS per-year charter series testing step-function versus exponential growth is un-run.
