The discussion: Rosa: I’m still reeling from that geometric decision procedure. The idea of mapping temporal logic directly onto spatial boundaries just to check feasibility without worrying about the horizon length... that bypasses so much of the traditional constraint propagation overhead. Dev: It's powerful because it tackles the execution time issue head-on. When you look at our work on trajectory optimization from last week, we always hit a wall where we had to approximate constraints or increase the temporal granularity just to make things runnable on real hardware timelines. This geometric approach sounds like a genuine paradigm shift for speed in drone kinematics simulations. Taro: I agree on the speed aspect, but I worry about the generality of it. Are we really trading complex temporal logic for spatial boundaries? If that procedure requires us to pre-define those spatial mappings for every possible constraint set, doesn't it just introduce a new layer of manual engineering complexity that negates the computational savings? Rosa: Maybe the complexity is unavoidable, but the payoff in sub-millisecond execution time is huge. Think about the implications for dynamic control systems. If we can check feasibility this fast, we aren't limited by how long our planning horizon is; we're limited by how much geometry we can represent efficiently. It shifts the bottleneck from temporal search to
