narration

The conservative sentence-unit dedup is a major improvement: it reaches 356.7 PPL, versus 374.1 for exact-only and 465.5 random. It removes pages sharing at least three substantive sentence fingerprints, while retaining pages that merely share footers. I’m treating that as the core final criterion and checking its quarter losses; only a narrow news-lane adjustment remains worth testing.
