Formal 'Aha!' events meeting all definitional criteria occur in fewer than 2% of problem-checkpoint pairs even under lenient thresholds, with no consistent positive effect on accuracy. However, an entropy-gated intervention that forcibly triggers reconsideration when models are uncertain yields consistent accuracy gains (+8.41pp on MATH-500, more modest gains on other domains), suggesting that model uncertainty identifies instances where external prompting for reflection is beneficial. These findings reframe mid-trace reasoning shifts as symptoms of inference instability rather than evidence of genuine intrinsic self-correction capability.",
