Governing question: What invariant is about to exist, and does it persist through what happens next?
The City exposes two synchronized layers rather than one flattened chain. Public Octet question cycle: SPECTRA → Fold → Murmuration → Mnemosyne → Density → Horizon → Wave → Identity → SPECTRA. Executable dependency order: SPECTRA → Fold → Density → Murmuration → Horizon → Mnemosyne → Wave → Identity → SPECTRA_REVEAL → SCORE. The canonical machine contract is Octet Experiment Packet — Cross-Lab Transport and Verification Contract. Open Horizon · Horizon — Prospective Forecast Console.

$$ \mathcal M_t:(X_{t-1},X_t)\longmapsto(\widehat\tau_{\rm top},\Delta\widehat\beta_q,\widehat P_{H_q}). $$
The forecast must be written before the target state is revealed. It predicts the next topology-changing time, birth/death sign, post-transition Betti number, and post-transition harmonic projector.
Given observed positions $X_t=\{x_i(t)\}$,
$$ v_i(t)=x_i(t)-x_i(t-1),\qquad \widehat X_{t+1}=2X_t-X_{t-1}. $$
Then
$$ \widehat X_{t+1}\rightarrow\mathcal R_\epsilon[\widehat X_{t+1}]\rightarrow\widehat\Delta_1\rightarrow\ker\widehat\Delta_1\rightarrow\widehat P_{\rm harm}. $$
with $\widehat\beta_1(t+1)=\dim\ker\widehat\Delta_1$ and $\Delta\widehat\beta_1=\widehat\beta_1(t+1)-\beta_1(t)$.
For each pair of agents,
$$ r_{ij}=x_i-x_j,\qquad u_{ij}=v_i-v_j, $$
and an edge crossing occurs when
$$ \|u_{ij}\|^2\tau^2+2(r_{ij}\cdot u_{ij})\tau+(\|r_{ij}\|^2-\epsilon^2)=0. $$
