proof audit
Not a CodeRabbit alternative. Keep the reviewer. Proof does not leave a suggested patch on line 74.

02 · The distinction
Even when a review tool tries to map your software, even when it tries to remember last time, it is still AI. Non-deterministic. A different answer on the next run.
That comment lives in their product. You do not own it. You cannot re-run it. You cannot hand it to an agent as a file in the repo. Next week the model has another opinion.
Proof is the opposite. Every claim needs evidence. No reproducer, no finding. The same inputs give the same result. What it writes down, you keep.
03 · Same pull request
The reviewer looks at this change. Proof looks at the corpus you already own.

The ticket. The diff. The tests the agent wrote with the function. This is what an AI reviewer is handed.

Not consulted. The signed requirements are still sitting in the repo.

Those comments live in their product. Run it again and they move. You do not own them.
Hidden knowledge baseYour corpus
Drawn for this page. Same shape as the two intakes on the homepage: what the work starts with. Qodo and Greptile sit with CodeRabbit.
04 · What you keep
You keep the approved requirements, fix-ready issues, evidence corpus, agent access, change history, and gate in your own repository.
Intent recovered from the code. Hazard analysis. The hazards themselves. The tests, including MC/DC. Agents work against that graph: they write tests to cover it, they receive the requirement and the reproducer before they edit a line.
When Proof finds an issue it is not an AI comment. It is confirmed with a reproducer. Everything that runs stays yours.
05 · The honest loss
CodeRabbit still wins at reading this pull request and leaving a comment a person can act on, fast, in GitHub.
Keep the reviewer if you want that UX. Add Proof for the corpus you own, and for findings that do not change when you run them again.
