Opus 4.6 had no issue correctly identifying and mitigating a hairy out-of-order state corruption issue involving a non-trivial sequence of runtime conditions from thrown errors and failed recoveries. This was simply from having access to the code repository and a brief description of the observed behavior that I provided. …
