gauss_same_sign_scaled_source_unique

Alpha v34 checked-use theorem · independently closed; not Stable

Equal lower signs or equal reflected signs force equality of the bounded source residues.

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.

Structural proof guide

Generated structural guide

Equal lower signs or equal reflected signs force equality of the bounded source residues.

Use the direct prerequisites prime_scaled_same_target_unique as previously established PA formulas.

The proof proceeds by case analysis (3).
