lucas_digit_chain_initial_value

Alpha v34 independently verified · alpha_closed; checked-use authorized; not Stable

The zeroth quotient of every coherent beta-coded digit trace is exactly its original natural input.

Current library: Alpha v34, 4,223 checked-use theorems; Stable remains 432. Historical first admissions, original proof editions, and non-admitted aliases are preserved. Exact original first-admission records.

Constructive proof overview

Generated structural guide

The zeroth quotient of every coherent beta-coded digit trace is exactly its original natural input.

The unchanged tactic script uses 0 declared prerequisites and contains 10 exact native proof lines.

dependency-curried kernel-checked theorem body; Alpha enrollment and checked-use authority follow separately sealed release evidence; Stable membership remains unchanged

Historical empty-context replay experiment only; that experiment persisted no certificate and granted no release authority. Current checked use follows separately sealed, independently verified proof bundles; there is no Stable promotion.

Formal native tactic body

Dependencies are introduced as named hypotheses before line 1. Local theorem links identify exact declared prerequisites. This exact body belongs to a complete independently kernel-checked constructive proof bundle and has Alpha checked-use authority; it does not imply Stable membership.
