Structural proof guide

Pointwise bounded decoded prefixes have ordered finite products.

Direct prerequisites: beta_product_zero, beta_product_succ_decompose, le_succ, le_refl, mul_le_mul. The authored body proceeds by structural induction (1), case analysis (8), intermediate claims (8), equality transport (4).

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.
