The requested theorem forced_of_scalar_uniqueness and its parent module IndisputableMonolith.Cost.Ndim.Uniqueness are not present in the supplied slice of the Recognition Science canon.
While the wider framework heavily relies on the uniqueness of the reciprocal-symmetric cost function $J(x) = \frac{1}{2}(x + x^{-1}) - 1$ (central to step T5 of the forcing chain), the specific module extending or formally applying this uniqueness in N-dimensional or scalar contexts is missing from the provided source code. Consequently, I cannot break down the formal statement, analyze its visible dependencies, or explain its specific role and limits within the formal library.
