about

nx_evolve.nx -- X-EVO-001: the EVOLUTION HARNESS (operator self-sufficiency arc; configured from the EC taxonomy evo_params.tsv, not invention). Rung 1 validates the MACHINERY on a fitness with a KNOWN optimum (you cannot trust an optimizer you cannot verify) -- then rung 2 swaps fitness_id for a GATE permil (the exceed: we grow evaluators). Every EC operator from the taxonomy, wired: population = candidate integer vectors selection = TOURNAMENT (best-of-k) mutation = per-gene +-1 at mutation_rate elitism = best carried unchanged generation = one loop; best logged (lineage) termination = convergence streak seeding = xorshift64 from cfg seed (FIXED-PER-RUN reproducibility law) diversity = tournament_k tunes greed<->variety (the niching knob) fitness 0 = -sphere(target) (unimodal, optimum known = target vector, fitness 0) fitness 1 = -rastrigin-ish (multimodal: -(sum (g-t)^2 + 8*(g!=t)) -- many basins) cfg ints: pop gens mut_rate_inv tour_k dims seed fitness_id target (mut_rate = 1/mut_rate_inv per gene per gen). Durable: EVOLVE-GEN + EVOLVE rows -> knowledge/status/evolve.log. Exit 0 = converged to optimum; 1 = did not. argv[1..]=cfg override ints (gates drive scratch configs deterministically). license_tier: ORIGINAL
