Field operators emerge from discrete bit density through three steps:
\[\rho_{\text{bit}}(\mathbf{r}_i) = \sum_{\text{vertices}} n_{\text{DI}}(\mathbf{r}_i)\]
\[\tilde{\rho}_k = \sum_i \rho_{\text{bit}}(\mathbf{r}_i) \, e^{-ik \cdot \mathbf{r}_i}\]
\[\hat{\phi}(\mathbf{r}) = \lim_{\text{lattice} \to \text{continuum}} \sqrt{\frac{1}{N_{\text{vertices}}}} \sum_k \frac{\tilde{\rho}_k}{\sqrt{2\omega_k}} \, e^{ik \cdot \mathbf{r}}\]
Creation/annihilation operators \(a^\dagger_k, a_k\) emerge from lattice mode counting with commutation \([a_k, a^\dagger_{k'}] = \delta_{kk'}\) from phase geometry. Fock space arises naturally from counting lattice mode occupations.
