lte_power_one_exact

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

The relational first power is constructed, not supplied as an oracle.

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 relational first power is constructed, not supplied as an oracle.

The unchanged tactic script uses 3 declared prerequisites and contains 10 exact native proof lines.

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.
