What is git bayesect?

Git bayesect is a Bayesian version of git bisect for debugging flaky tests with probabilistic failures.

How does git bayesect fix flaky tests?

It models failure probabilities with Bayes' theorem, picks info-rich commits via entropy, and converges faster than traditional bisect.

Is git bayesect better than git bisect?

Yes, for non-deterministic tests like LLM outputs or races — where bisect gives false positives.
