\(\pi(N) = N_{\rm gen} \times p_{D_{\rm mixed}} = 3 \times p_5 = 3 \times 11 = 33 \;\Rightarrow\; N = 137\)

As \(\tau\) descends the bilateral scale ladder from unification to the electromagnetic scale, each prime rung is a resonant cavity — a threshold where a new species of crossing fires. 33 thresholds are traversed: three generations, each crossing \(p_5=11\) mixed-dimensional rungs. The prime at position 33 is 137. The EM coupling is \(\alpha = 1/137\).
