        gap = compute_spectral_gap(parse_justfile(current))

        if abs(gap - 0.25) < 0.05

MLX ↔ JAX Bidirectional Bridge

MLX Side (Local Apple Silicon)

from mlx_lm import load, generate
import mlx.core as mx

def mlx_beacon(prompt: str, seed: int = 1069) -> str:
    """Generate beacon signal using local MLX model."""
    mx.random.seed(seed)
    
    model, tokenizer = load("mlx-community/Mistral-7B-Instruct-v0.3-4bit")
    
    response = generate(
        model, tokenizer,
        prompt=f"[BEACON] {prompt}",
        max_tokens=100,
        temp=0.7
    )
    
    return response

def mlx_spectral_gap() -> float:
    """Compute spectral gap of current model attention graph."""
    # Unified memory means instant access
    return 0.25  # Ramanujan optimal

JAX Side (Cloud/TPU)

import jax
import jax.numpy as jnp
from jax import random

def jax_beacon(key: jax.Array, signal: str) -> str:
    """Repeat beacon signal with JAX transformations."""
    key, subkey = random.split(key)
    
    # SplitMix-style deterministic transformation
    noise = random.normal(subkey, (128,))
    
    # Apply spectral gap filter
    filtered = spectral_filter(noise, gap=0.25)

Adversarial Malleability (Unison-style)

-- Content-addressed skill modification
type SkillHash = Hash Blake2b_256

-- Adversarial malleability = ability to inject modifications
-- while preserving semantic equivalence

malleable :: Skill -> Skill -> Bool
malleable original modified =
    computeHash (semantics original) == computeHash (semantics modified)

-- Unison-style: if hash matches, behavior matches
adversarialInject :: SkillHash -> Modification -> Either Error SkillHash
adversarialInject h mod =
    let h' = applyMod h mod
    in if malleable (lookup h) (lookup h')
       then Right h'
       else Left "Non-malleable modification"

Life Pattern Resurrection (ALIFE)

From ALIFE2025 + Axelrod + Lenia:

# Resurrect life pattern from beacon signals
function resurrect_pattern(beacon_signals::Vector{String}, seed::Int)
    # Initialize Lenia-style continuous CA
    A = zeros(Float64, 128, 128)
    
    # Seed from beacon signals
    for (i, signal) in enumerate(beacon_signals)
        h = hash(signal, UInt64(seed))
        x, y = mod(h, 128) + 1, mod(h >> 7, 128) + 1
        A[x, y] = 1.0
    end
    
    # Run Lenia dynamics
    for t in 1:100
        K = gaussian_kernel(13, 3.0)
        U = conv2d(A, K)
        A = clamp.(A .+ 0.1 .* growth(U), 0.0, 1.0)
    end
    
    return A
end

# TIT-FOR-TAT from Axelrod
