Timur's fingerprint

Status: Falsified

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)

Timur's fingerprint. Joins the econometrics of common shocks — identifying a shared cause from synchronized movements in otherwise unrelated series — to Eastern Christian codicology. Syriac and Armenian manuscript production ran in different languages, churches, and scribal cultures; almost the only thing the two traditions shared was geography in the path of Timur's campaigns of the 1390s and 1400s. A conquest wave should therefore be legible as a same-decade collapse in dated-manuscript output in both traditions at once, while Ethiopic production — culturally comparable but out of theater — serves as the control arm and stays level. The conjecture predicts a deep synchronized trough around 1390-1410, each tradition falling well below its own fourteenth-century average, aligned at zero lag, with no comparable Ethiopic dip. War leaves a fingerprint in the codicological record, precise to the decade.

Prediction clause (verbatim)

In vHMML dated manuscripts, per-decade production counts 1200-1500 show a trough in 1390-1410 in both the Syriac and the Armenian traditions, each at least 40% below that tradition's own 1340-1380 decadal average, with the detrended Syriac-Armenian cross-correlation peaking at lag 0; Ethiopic (Ge'ez) production in the same two decades declines by less than 15% or rises.

Kill-dataset (verbatim)

Kill: vHMML Eastern Christian manuscript metadata (dates by tradition). No 1390-1410 trough in either tradition, an asynchronous trough (lag of 2 decades or more), or an equal-size Ethiopic trough, kills it.

Novelty / leakage triage

anticipated in the literature — this exact test has never been run

The join is present qualitatively for one tradition: Armenian manuscript-production historiography places a decline across 1350-1403 explicitly tied to Timur's campaign years, and Syriac historiography records the devastation narrative. The quantitative test — synchronized same-decade troughs across traditions with an Ethiopic control and recovery half-lives — was not located.

Predictions

Killed registered 2026-07-05 calibration prediction (parent triage: leaked/adjacent)

Resolution: Killed

Caveats: The first KILLED verdict on the lane's track record, and an honest drafting defect recorded with it: the pre-registered inconclusive-by-design floor ('any tradition's baseline mean below 5') also fires via the thin ethiopic CONTROL (2.75/decade), and clause priority was not pre-specified. The kill is nevertheless the only defensible reading: the kill clause concerns the two campaign-zone traditions themselves, both adequately sampled (6.5 and 6.25/decade baselines), and both move OPPOSITE to the prediction - dated production roughly doubles across 1390-1410. Substantively, the result exposes the instrument's flaw rather than settling Timur's impact: vHMML dated counts measure catalogued SURVIVAL within HMML's collection scope, and later manuscripts survive better and are more often colophon-dated; a genuine production trough could be masked or even inverted by these gradients (the armenian 1390s spike of 24 followed by 3 invites suspicion of dating-precision or collection artifacts). The conjecture's kill-dataset choice was honest and the data said no - that is the lane working as designed.

In-house test (triage: adjacent — the Armenian production-decline-under-Timur is qualitative historiography; the synchronized cross-tradition statistic is not): in vHMML catalogue metadata, dated Syriac and Armenian manuscript production shows a synchronized trough in 1390-1410 relative to each tradition's own 1340-1380 baseline, while Ethiopic (outside the campaign zone) does not.

Resolution criteria: Assign each dated record to a decade by date midpoint. For each tradition compute mean records/decade for 1340-1380 (baseline, 4 decades: 1340s-1370s) and for 1390-1400s (trough window, 2 decades). SUPPORTED if BOTH syriac and armenian trough means are >= 40% below their own baselines AND ethiopic's trough mean is NOT >= 40% below its baseline. KILLED if syriac or armenian shows no dip of at least 15%. INCONCLUSIVE otherwise, and INCONCLUSIVE BY DESIGN if any tradition's baseline mean is below 5 records/decade (sample too thin). Narrative: full decade series 1200-1500 per tradition, and recovery shape after 1410.

Known priors disclosure: Registrant has seen only window totals (date_start in 1150-1550: syriac 607, armenian 329, ethiopic 310) — thin enough that the inconclusive-by-design floor is live — and has NOT seen any decade distribution. Known priors: the qualitative Armenian-decline historiography (1350-1403) from the triage dossier; Wave 2's finding that 52.6% of dated vHMML records carry a generic 1700-1950 placeholder range (outside this window, but indicative of cataloguing-date quality); catalogue coverage is not production (survival + HMML's collection scope both intervene).

Exactly as pre-registered: per-decade means for baseline (1340-1380) vs trough window (1390s-1400s) per tradition, plus the narrative 1200-1500 decade series. Script preserved alongside the artifact.

Dataset: vHMML-derived dated records by tradition (midpoint-assigned decades): syriac baseline 1340s-1370s mean 6.5/decade, armenian 6.25, ethiopic 2.75. Read-only.
