beta_witnessed_two_square_factor_product

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

A represented decoded factor supplied existentially at every bounded index suffices for an explicit representation of the whole product.

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.
