crt_normalized_prefix_solution_unique

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

Normalized representatives are literally unique at every list LCM; the zero case uses congruence equality, not a false bound below zero.

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.
