Generated structural guide
Every actual left factor of a Gaussian unit has a constructed inverse, without an irreducibility assumption.
The unchanged tactic script uses 3 declared prerequisites and contains 32 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.

Proof checkpoints
This is a reading aid, not a new proof or a proof-tree certificate. Checkpoint groups are consecutive commands, not inferred branch boundaries. Every step links to the preserved script.
