Not sure this is a coherent thought since I’m sleep deprived, but I’ll share it anyways before going to bed: Rather than predicting what the phantom’s planning module would do, is it be cheaper to reuse your own planning module for that prediction (assuming it’s already closely enough converged towards the phantom’s one)? For predicting other agents, you’d probably build a model of their planning module, but for predicting an agent similar enough to yourself, you might be able to reuse machinery rather than build yet another model?
