lucas_base_p_digit_prefix_exists

Dependency-curried candidate body; not Alpha-enrolled; no checked-use authority

Every finite beta-coded natural prefix has actual beta-coded quotient and least-significant digit prefixes for each nonzero base.

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.
