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

The recorded canonical leading inverse is unique even when the source and target beta encodings are not.

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