Structural proof guide

Every decoded quotient entry at or beyond the dividend is zero.

Direct prerequisites: prime_power_quotient_zero_of_exponent_gt. The authored body proceeds by case analysis (6), intermediate claims (3), equality transport (3).

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.
