Definition G.1 — Pre-Closure Phase

A dynamical regime is said to be in a pre-closure phase if:

1. the state $\Psi(t)$ evolves smoothly and deterministically,
2. all local observables remain finite,
3. the temporal closure functional satisfies $\mathcal{C}[\Psi]=0$.

Pre-closure does not imply the absence of dynamics. Rather, it denotes the absence of sustained gravitational structure and temporal self-binding.
