The definition supplies a closed rational interval for φ^102 obtained by squaring the φ^51 interval. Researchers bounding the galactic ratio τ★ / τ₀ ≈ 5.75e29 cite it inside the Recognition Science numerics layer. It is realized by a direct call to the positive-interval multiplication operator on the φ^51 data.

claimLet $I_{51}$ be the closed rational interval containing φ^51. The interval $I_{102}$ for φ^102 is defined by $I_{102} = I_{51} × I_{51}$ via multiplication of positive intervals.

background

The module develops rational interval bounds on powers of the golden ratio φ to constrain the galactic ratio τ★ / τ₀ ≈ 5.75e29. An Interval is a structure with rational endpoints lo ≤ hi. The mulPos operation multiplies two intervals when both lower bounds are positive, setting the product lower and upper bounds and proving validity by monotonicity of multiplication on positives.

proof idea

The definition is a one-line wrapper that applies mulPos to phi_pow_51_interval with itself, passing the positivity witness phi_pow_51_lo_pos twice.

why it matters in Recognition Science

This interval is used to build phi_pow_140_interval and the comparison theorems phi_pow_140_lt_ratio and phi_pow_142_lt_ratio_1_3 that place φ^140 below the galactic ratio. It therefore supports the Recognition Science claim that the phi-ladder and eight-tick octave produce the observed galactic scale. The parent step is the forcing of φ as self-similar fixed point in the unified forcing chain.
