Sources include network simulators, formal checkers such as Batfish or YANG validation, and closed-form physics such as orbit propagation and link budgets Impose action budgets and hidden state so that exhaustive search does not work and the task measures diagnostic policy rather than brute force Define invariants, and make any repair that breaks a previously satisfied property fail the episode Calibrate difficulty by running frontier models against each task, then analyze failures to confirm they come from domain reasoning rather than ambiguity or broken grading Work with research partners inside and outside the team to turn measured capability gaps into published findings
