Introduces the Wiggle Framework, a unified stress test for the epistemic stability of LLM judges, measuring mechanical consistency, single-turn conviction, and multi-turn persistence across 14 tasks. Finds that all 9 studied frontier models flip verdicts substantially under pressure, and that successful pressure is usually net-corrupting relative to ground truth.
ProofGrid is a benchmark suite that evaluates LLM reasoning through machine-checkable proofs using minimal formal notation, with tasks in proof writing, checking, and gap-filling, revealing progress and remaining limits including epistemic instability.
