The rapid evolution of artificial intelligence in healthcare has spotlighted the need for reliable home monitoring systems to verify patient adherence to prescribed regimens. This conceptual manuscript introduces a novel framework for adherence verification leveraging passive signals—such as ambient sensors, wearables, and environmental data—while robustly addressing data missingness. Traditional approaches often falter in real-world deployments due to intermittent signal capture, leading to inaccurate assessments and compromised clinical decisions. We propose the missingness-resilient adherence orchestration network (MRAON), an architectural construct that integrates multi-modal passive signals through layered processing, incorporating missingness-informed imputation strategies and adaptive detection mechanisms. The framework emphasizes theoretical infrastructure for signal fusion, risk propagation modeling, and governance of decision confidence under uncertainty. By synthesizing recent literature on passive monitoring and missing data handling, we delineate how MRAON enhances verification robustness without relying on empirical evaluations. Key conceptual formulas capture dynamics like decision confidence as a function of missingness severity and monitoring burden influenced by resource allocation. This work advances theoretical discourse in AI-driven healthcare analytics, offering a blueprint for scalable, ethical home monitoring systems that prioritize patient autonomy and data integrity. Ultimately, MRAON paves the way for future integrations in chronic disease management, reducing healthcare burdens through intelligent, passive adherence detection.
