Trapped-ion companion: alongside Microsoft + Quantinuum's trapped-ion error correction, not a competitor but a companion sandbox. Run their abelian code class and our non-abelian Fibonacci string-net (d_τ = φ) on identical machinery under real Quantinuum H2 / IonQ Aria noise, and see the frontier their work doesn't cover: Fibonacci is braiding-universal, so its magic-state distillation cost drops to zero. Honest, code-capacity, computed live.
