signed_cofactor_minor_prefix_extend

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

Appending one genuinely constructed signed minor preserves every previously encoded cofactor record.

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.

Exact expanded first-order arithmetic statement

Constructive proof overview

Generated structural guide

Appending one genuinely constructed signed minor preserves every previously encoded cofactor record.

The unchanged tactic script uses 2 declared prerequisites and contains 54 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.

54 script commands · 19 reading checkpoints · 3 local claims

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.

Long local formulas use this family’s existing definitions. Each new abbreviation was expanded back to the identical native formula, including its free-variable context. The original edition is preserved below.
