But they are shipping code they cannot verify. At scale, in critical systems, this is a ticking clock. Mistral shipped Leanstral on March 16, 2026. It is a different kind of answer to the AI code quality problem—not more guardrails, not better test generation, but formal mathematical proof. Leanstral generates proofs that your code is provably correct against formal specifications. That is a fundamentally different level of verification from “the tests pass.” ...

You open the laptop, squint at the alert, and the next 45 minutes look like this: Datadog for metrics, GitHub for recent commits, Slack to find out who made the last deploy, Elasticsearch for logs, and then—finally—you find it.
