graph: route dependent external momenta in hand-written numerators A numerator that names the dependent external momentum P(i, ...) (the one fixed by momentum conservation) left it unbound: routing rewrites only edge momenta Q(e, ...), and only the independent P(i) are bound. Write each dependent P(i, ...) as its edge momentum Q(e_i, ...) before routing, so it goes through the same signature as the propagators. Numerators without a dependent P are unchanged (nothing is registered). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
