Shared Reality as the Synchronization of Realized Sectors examines how shared reality may be understood once observer-dependence is taken seriously. Rather than treating objectivity as a world free of observers, this paper proposes that shared reality may be understood as the maintained overlap and re-synchronization of multiple observer-dependent realized sectors. On this view, objectivity is not the absence of perspective, but the sustained coherence of realized sectors across observer networks. The paper argues that overlap does not require identical content. What is shared is not every local feature, but enough recoverable compatibility of structure for reference, correction, and coordinated action to remain possible. Shared reality is therefore not a pre-given container surrounding observers, but an ongoing synchronization achievement, sustained through language, record, measurement, science, law, and other institutional forms. Within this framework, sovereign observers are not opposed to shared reality, but are necessary to it. A synchronizable world requires observers who can sustain local depth without collapsing into conformity or hardening into closure. The paper also considers the role of artificial systems in the synchronization layer, arguing that they function less as independent sources of objectivity than as amplifiers, mediators, and stabilizers of inter-observer coordination. At the same time, the paper explicitly limits its scope: it offers a structural account of shareability, not an exhaustive empirical sociology of coordination. This paper is the seventh in the Selection Geometry / Intent Physics sequence. Paper VI asked how reality formation becomes lived from the observer side. Paper VII asks how lived realities remain shareable. It therefore serves as the bridge from observer-experience to the synchronization layer of science, institutions, and civilization-scale coherence.
