impulse (field)
the $\Delta\phi^*$ field of a signal: the proven shift in focus the signal carries. cybergraph names the field and gives it its slot in the structure; it routes the complete definition to the component that owns it.
how $\Delta\phi^*$ is computed (locally, on the neuron's neighborhood), what it is worth (self-minted reward), and how it is conserved per epoch — the complete form — is the tru's. see impulse for the full specification.
cybergraph's only role: the field exists in the signal, it is covered by the proof σ, and a verifier checks that proof. nothing more.
