Generated structural guide
An exact decoded-prefix recoding preserves every formal coefficient at the same annotated length.
The unchanged tactic script uses 1 declared prerequisite and contains 27 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.

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.
