Couplets survive the conquest
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)
Couplets survive the conquest. Connects Nahuatl verbal art's signature device — the difrasismo, a fixed semantic couplet such as in atl in tepetl for city — to the differential survivability of oral genres under alphabetic transcription: formal oratory (huehuetlahtolli) was memorized performance in which coupling was the meter, while annalistic prose was content-first record keeping. If the sixteenth-century transcription projects captured genres rather than homogenizing them, couplet density should mark the genre boundary sharply, an orality fingerprint surviving the medium change intact.
Prediction clause (verbatim)
Count semantic couplets per 100 clauses in the huehuetlahtolli of Florentine Codex Book 6 and in a matched span of Nahuatl annals. Primary clause: Book 6 oratory shows at least three times the difrasismo density of the Codex Aubin annals. Secondary: within Book 6, quoted speech outscores narrative connective tissue. The verdict follows the primary clause.
Kill-dataset (verbatim)
Kill: the Dibble and Anderson edition of the Florentine Codex, Book 6, and Dibble's edition of the Codex Aubin, both with the Nahuatl fully transcribed.

Novelty / leakage triage
provisional — model-triaged, shepherd review pending
A provisional first pass authored by the model (Opus), not yet confirmed by the shepherd. It carries the same dated-search requirements as an authoritative verdict but is excluded from every headline figure and cannot underwrite a prediction until a shepherd confirms it. Provisional reading: Adjacent (closely related prior work exists).
That semantic couplets (difrasismo) are the signature device of formal Nahuatl oratory (huehuetlahtolli) while narrative/annalistic prose is comparatively unmarked is an established view: Garibay named the difrasismo and treated parallel coupling as the mark of the high oratorical register, and Bright's study of Nahuatl parallelism analyses exactly this couplet structure of formal speech. So the genre-boundary-marked-by-couplet-density claim is qualitatively held. Not located: the specific comparative measurement -- Florentine Codex Book 6 oratory at >=3x the difrasismo density of matched Codex Aubin annals -- which is the item's decidable operationalization.
