Structural proof guide

A prime in the remaining cofactor raises a selected power.

Direct prerequisites: mul_assoc, multiple_mul_left, power_divides_successor_of_cofactor. The authored body proceeds by case analysis (1), intermediate claims (2), equality transport (1).

Formal native tactic body

Dependencies are hypotheses of the historical Alpha-v12 body receipt. The complete historical Alpha-v18 proof bundle independently checks every dependency; current Alpha v25 preserves that checked theorem use without changing Stable membership.
