TEBench - Breaking Test Identification: leaderboard

Metric: Identification F1 (%) for tests the change breaks: the tests the agent modified, deleted (method level) or added (file level) against the developer's own test changes, on TEBench (314 commits from 10 Java projects): given the project at the commit with its production changes but not its test changes, the agent edits the test suite in an isolated worktree with default agent settings; higher is better.
