Generated structural guide
Every zero-based pair order has a beta code of successor-valued factors.
Use the direct prerequisites beta_successor_lift_exists as previously established PA formulas.
The proof proceeds by direct introduction and elimination.

Formal native tactic body
Dependencies are introduced as named hypotheses before line 1. Linked names are exact direct references. This Alpha-v25 checked-use theorem is independently kernel-checked when replayed; it is not a Stable theorem.

This is a reading aid, not a new proof or a proof-tree certificate. Checkpoint groups are consecutive commands, not inferred branch boundaries. Every step links to the preserved script.
