An inverse tell: the *absence* of messy human punctuation. Current models use exclamation marks at ~2% of the human rate, ellipses at ~10%, question marks at half. Nothing dangles, nothing trails off. Too clean to be human.
Listed but not yet auto-scored (requires enough text to measure absence).
model specificity: cross-model; exclamation suppression overshot below human levels after the sycophancy corrections
