narration

The similarity sweep peaked at weight 3.0 (dev perplexity 375.1); pushing to 5.0 regressed to 383.6, so I’ve fixed the published criterion at the observed optimum. I’m now regenerating the selection solely through the deliverable script, then I’ll verify exact token coverage, uniqueness, bounds, and one clean end-to-end evaluation.
