Generated structural guide
In an actual nonzero product of two Gaussian nonunits, both natural factor norms are strictly smaller than the product norm.
The unchanged tactic script uses 5 declared prerequisites and contains 56 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.
