What is Git Bayesect and how does it work?

Git Bayesect is a Bayesian upgrade to git bisect for flaky tests. It models failure probability shifts across commits using Bayes' theorem and picks tests for max info gain.

Will Git Bayesect replace git bisect?

Not yet — use it when tests flake probabilistically. Complements bisect for deterministic cases. Expect git integration soon.

How do I install and use Git Bayesect?

`pip install git_bayesect`. Then `git bayesect start --old `. Test, then `git bayesect fail` or `pass`. Priors optional for hunches.
