Proof

These are real dependency-update pull requests from public repositories under permissive licenses, captured as they were: the base commit and the head commit. The agent that runs in a customer's own GitHub Actions ran against each one on our own machine, on our own Anthropic key. Nothing was pushed, commented or opened on anyone's repository. "Fixed" means the repository's own test suite passed before and after the change, flaky tests excluded by running the baseline more than once (three times in process, twice when run the way a press runs); it does not mean the change was reviewed by the maintainers or merged.
