Finding

The complete NT/MT field changes by−130 at every common node through Arphaxad and by0 from Shelah onward. This makes the insertion support explicit. The130,460,70 and BJ57 measures retain their source-specific roles even when name bookkeeping aligns.

Reassessment

Generalize the retained-biography distinction as a subdivision rule.
