Sentence-level stylometric classifiers

Mythic, Historical, and Other from Stylometric Features

These models predict sentence labels using style-oriented feature families derived from the current gpt-5.6-luna grammar parses. The evaluation is cross-validated on the parsed subset and compared with a majority-label chance baseline inside each fold.
