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

The last residue/modulus pair of a solved successor list satisfies its actual congruence.

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.
