Neumes ride the rivers
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 great neume 'dialects' — German, French, Aquitanian, Beneventan sign families — are usually mapped against dioceses and monastic families, and freight geography is usually left to economic historians. This conjecture joins them: the boundaries between neume families track medieval bulk-transport basins (navigable river systems plus their cartage corridors), not ecclesiastical province lines. The mechanism is mundane: exemplars, cantors, and correction visits moved along the same cheap routes as wine and grain, so a scriptorium's graphic habits were resupplied from its freight hinterland, while a diocesan border crossing a watershed was musically porous only where a road crossed it too. If this holds, chant palaeography becomes a proxy map of ninth-to-eleventh-century transport costs, and the standard picture of notation spreading down church hierarchies breaks.
Prediction clause (verbatim)
Primary clause (the verdict follows it): in a classification of 10th-12th-century notated sources by neume family and origin, watershed/route-basin assignment predicts neume family significantly better than ecclesiastical province assignment (higher classification accuracy in a held-out test, with a chi-squared or information-gain margin that survives controlling for distance). Secondary clause: at least two documented cases exist where a diocese split by a watershed shows two neume families within one diocese.
Kill-dataset (verbatim)
Cantus Database / Cantus Index source records (origin, date, notation type per source), joined to published medieval route and river-navigability reconstructions (e.g. the ORBIS-style route sets and the maps in the Atlas zur Kirchengeschichte); the test is a distribution comparison over these public tables.
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.

Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Regional neume families and their geographic mapping are standard palaeography, and prior work already shows secular (not ecclesiastical) geography channeling chant exchange — e.g. post-Verdun political boundaries structuring trope transmission — so the mechanism of non-hierarchical geographic channeling is anticipated; the specific transport-basin classifier is the un-run statistic.
