Walsh and Knuth extend an influence-network model to conditional force relations. Observer coordination, rate assignments and approximations underlie the calculation. They acknowledge incomplete understanding of a required connectivity condition. No empirical UAP mechanism is demonstrated.
Knuth develops an influence-network model that conditionally reproduces familiar1+1-dimensional physics relations. Coordinated observers and rate assignments are assumptions. He acknowledges a microscopic coordination problem; gravity extensions remain suggestions. The essay provides no UAP observation or independent empirical validation.

Knuth and Walsh develop a model of directed influence with coordinated observers, recovering relativistic kinematics and event-count action in1+1 dimensions. Their treatment of force and time dilation has weak-influence and other approximation limits. The higher-dimensional extension remains unfinished; this is theoretical work rather than empirical UFO evidence.
