Ptolemy travels with bodyguards
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 Almagest, the central book of ancient astronomy, rarely travels alone in its manuscripts. The surprising connection is that each translation version travels with its own characteristic convoy of satellite texts — introductions, canons, star-lists — stable enough that a codex's translation can be identified from its table of contents without reading a word of Ptolemy. The mechanism is curricular: a translation entered circulation embedded in a syllabus, and exemplars were copied as curricular blocks, so the satellites are the fossilized teaching context of each version. If this holds, codex contents become a cheap classifier for fragmentary or unexamined witnesses, and the 'same text' in two versions is revealed as two different books in practice.
Prediction clause (verbatim)
In Ptolemaeus Arabus et Latinus codex descriptions, the co-occurrence profile of accompanying texts will classify a codex's Almagest version (Gerard of Cremona's Arabic-Latin, the Sicilian Greek-Latin, and others) with at least 80% accuracy under cross-validation, and each version will have at least two satellite texts present in over half of its codices but under one fifth of the rival version's. Primary clause: the 80% classification accuracy; the satellite-specificity clause is secondary.

Provenance
Run: Fresh agent generation · model: claude-fable-5
Composed blind by claude-fable-5 with zero tool use of any kind; the packet was generated entirely from the model's own knowledge and emitted as a single text message.
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
The corpus astronomicum literature (O. Pedersen) established that university astronomy circulated as canonical curricular blocks, and PAL catalogues codex contents for the Almagest versions; but a co-occurrence classifier identifying translation version from satellite-text profiles alone has not been built or proposed, so the exact operationalization is un-run.
