The golden ratio admits the infinite continued fraction with all partial quotients equal to 1. This definition records a finite prefix of exactly ten ones for use in summations that relate φ to Euler's number e. Researchers deriving constants from φ-forcing and J-cost exponentials would cite the list when approximating continued-fraction expressions. The definition is a direct literal assignment with no computation or lemmas.

claimThe finite prefix of the continued fraction for the golden ratio is the list of partial quotients $[1,1,1,1,1,1,1,1,1,1]$.

background

The module derives Euler's number from φ-summations and 8-tick probability normalization. J-cost is the non-negative cost of a recognition event, obtained as the derived cost of a multiplicative recognizer's comparator on positive ratios. Probability of a configuration is the squared norm of its amplitude vector. The exponential base e appears in distributions of the form P ∝ exp(-J/J₀) because only the exponential is invariant under differentiation.

proof idea

The definition is a direct literal assignment of the ten-element list of ones. No lemmas or tactics are applied; the value is supplied as a constant for later use in φ-related summations.

why it matters in Recognition Science

The definition supplies the continued-fraction coefficients for φ that the module invokes when exploring links between e and φ through J-cost exponentials and 8-tick normalization. It fills the φ-related continued-fraction slot listed in the module target. No downstream theorems reference it, so its role in larger derivations remains open.
