Purpose vs Randomness

Preferred Frame Writing β€” January 2026

One-Sentence Summary

We define the Acausal Purpose Invariant ($\mathcal{P}$), a scale-invariant metric that quantifies how strongly a structure resists the combinatorial entropy naturally associated with its size.

Summary

We introduce the Acausal Purpose Invariant ($\mathcal{P}$), a decibel-scale measure of how atypical a number’s prime ancestry is relative to a stochastic background. Empirical sweeps reveal a sharp probabilistic cutoff separating random structure from cost-paid persistence, reframing the detection of life, artifacts, and purpose as a problem of entropy suppression rather than intelligence.
