Constructive proof overview

Generated structural guide

Every normalized nonempty prime-field pair has the sharp bound against every actual coded upper sumset.

The unchanged tactic script uses 2 declared prerequisites and contains 38 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.
