The debate song is a guild handshake

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 jeu-parti was a staged verse debate between two named poets, and Arras in the thirteenth century produced hundreds of them. Arras also kept the membership necrology of its jongleurs' and burghers' confraternity — an actual roster of the town's organized performance world. This conjecture claims the debate-partner network and the guild register are the same institution seen twice: poets sang jeux-partis overwhelmingly with fellow confraternity members, because the form was a membership ritual — public proof of standing, staged before the guild's own judges — rather than open competition. The song is a handshake between dues-payers. If this holds, the first dense vernacular literary community in Europe was formally a mutual-aid society, and literary sociability can be read off institutional rosters rather than reconstructed from the poems.

Prediction clause (verbatim)

Of the jeu-parti partner pairs involving Arras poets in Langfors's corpus, at least 60 percent will have both partners attested in the Necrologe de la Confrerie des jongleurs et des bourgeois d'Arras, a co-registration rate at least three times what random pairing among named contemporary Arras poets yields; primary clause: the co-registration enrichment. The Jehan Bretel partnership network is the decisive subgraph.

Kill-dataset (verbatim)

Kill: Langfors's Recueil general des jeux-partis francais (partner attributions) against Berger's edition of the Necrologe de la Confrerie des jongleurs et des bourgeois d'Arras.

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

Searched the Arras necrology and jeu-parti poets. Berger's edition of the Nécrologe identifies many trouvères (Bretel, Adam, etc.) as confraternity members, anticipating the join, but the partner-pair co-registration rate against a random-pairing baseline is un-run.
