FaultLens pairs a fault-driven greedy selector with a mutation-independent diversity term covering probe families, cases, templates and time. Across twenty policies and 4.1M+ program-probe executions: 32 probes covered 99.0% of dynamically killable faults, the diversity term lifted scenario-family coverage from 84.6% to 94.9%, and deploying the suite took severe regressions in 15 of 20 program-environment groups down to zero. The authors are explicit that this is prioritized evidence and not proof, and they publish the budget, evidence source, split and misses. That's how a benchmark paper should report. (arXiv)
