The passage around this formula

where wiw_i scales each failure by how costly it actually was. Two agents can share an identical p^\hat{p} of, say, ninety-five percent, while one of them fails harmlessly - an unhelpful but reversible answer - and the other fails catastrophically - an irreversible transaction, a deleted repository, a wrong medical dosage recommendation - on that same five percent. No standard agent benchmark publishes R , because assigning a defensible wiw_i requires a judgment about real-world consequence that a replayable, sandboxed task suite is not built to carry, and because the tasks that would carry the highest weights are, not coincidentally, the ones too risky to include in an automated benchmark at all.
