Deep Implications — The GCD Kernel as Evolutionary Grammar

Precise mathematical mappings from GCD invariants to published evolutionary
phenomena, with empirical citations and quantitative verification.

PURPOSE: Show that each GCD identity (F+ω=1, IC≤F, IC=exp(κ), Δ=F−IC,
geometric slaughter, regime gates) has an EXACT correspondence to a
named concept in evolutionary biology, published and measured independently.

    """Compute the Fisher Information connection for a channel vector.

    The heterogeneity gap Δ = F − IC has a precise statistical interpretation:

    This IS the Fisher Information of the Bernoulli field for a shift
    in the mean parameter. The heterogeneity gap is the Fisher Information
    contribution from channel heterogeneity.

    In evolutionary terms: Δ measures how much INFORMATION about vulnerability
    is contained in the channel pattern. High Δ = high information about
    which channel will break. Low Δ = uniform robustness, hard to predict
    which channel fails.
