narration

The official files are now valid and reproducible, and the evaluated packed prefix is exactly 12,000,000 tokens. There is still ample time, so I’m doing one final local sensitivity check around the current equal allocation (small ±3–4% shifts); I’ll only replace the locked result if a nearby mixture gives a real improvement.
