This module isolates the cost of each prime as the J-function evaluated at that prime, treating primes as the irreducible transactions in the multiplicative ledger. Researchers building cost-twisted L-series or prime phase distributions cite it as the foundation for the spectrum. The module supplies definitions for primeCost and costSpectrumValue together with their immediate nonnegativity and monotonicity properties.

claimFor prime $p$, define prime cost $c(p) := J(p)$ where $J(x) = (x + x^{-1})/2 - 1$. The cost spectrum value at $n$ is the sum of $c(p_i)$ over the prime factorization of $n$, with $c(1) = 0$.

background

The J-cost function originates in the Cost module as the unique function satisfying the Recognition Composition Law J(xy) + J(x/y) = 2J(x)J(y) + 2J(x) + 2J(y). PrimeLedgerStructure establishes primes as the generators of the natural numbers under multiplication, per the fundamental theorem of arithmetic. This module extracts the restriction of J to primes to form the basis of the cost spectrum.

proof idea

This is a definition module, no proofs.

why it matters in Recognition Science

It supplies the prime cost spectrum that CostTwistedLSeries generalizes to characters and that PrimePhaseDistribution and RecognitionTheta rely on for their constructions. The module fills the step from the J-uniqueness (T5) to the spectrum basis in the forcing chain.
