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

Every actual appended prefix is the actual aligned sum of a genuine trailing-zero shift and the leading-padded singleton constant; the last and earlier entries are proved separately, including M=0.

Current library: Alpha v34, 4,223 checked-use theorems; Stable remains 432. Historical first admissions, original proof editions, and non-admitted aliases are preserved.
