<b>Edge-to-Cloud Heterogeneous Interaction Architecture for Structural Interoperability in Critical Industrial Olfactory Monitoring Networks</b>

Yet the architectural question they pose has been answered only partially by the orchestration literature. That literature has established how to deploy and manage applications across a Cloud-to-Things continuum, and has produced resilient architectures with self-healing mechanisms demonstrated under overload and saturation.

What remains unresolved is </i><i>placement</i><i>: which interoperability functions belong at the edge, which at the cloud, and by what criterion. This article argues that the governing criterion is not data volume or computational cost but the temporal tolerance of the interaction contract attaching to each function the maximum deformation an exchange can sustain before its recipient can no longer reconstruct the observation.
