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

Nine actual historical Pair constructors package the ten finite data fields without expanding a huge nested arithmetic numeral.

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.
