Transforming existing secondary hospitals into elderly care facilities is essential for addressing global aging and reducing carbon emissions. Traditional spatial evaluation methods often ignore how micro-kinematic perturbations, such as wheelchair turning radii, disrupt macro-building topologies. Clashes between new spatial demands and rigid boundaries like shear walls create systemic topological deadlocks, leading to unnecessary demolitions. To address this, a bottom-up multi-agent wave function collapse (WFC) heuristic framework is proposed. Floor plans are discretized into negotiating agents, with elderly care regulations abstracted into physical state templates. During dynamic envelope expansion, agents perform geometric calculations and spatial negotiations guided by a graph attention network. Simulations and practical applications across various secondary hospital types demonstrate significant efficacy in identifying topological bottlenecks and resolving systemic deadlocks. Results prove that remodeling resistance concentrates in specific bottlenecks rather than distributing linearly. Consequently, a surgical intervention strategy is proposed to maximize topological release with minimal structural cost. This research provides a novel quantitative algorithm for spatial resilience; it is hoped that this framework can serve as a humble decision-making reference for low-carbon elderly care adaptations and urban renewal.
