Solo developer Ian released Covenant 0.1.0 on Hex under the MIT license, a library that reads component contracts written in Markdown and YAML under contracts/ and fails the build when an obligation is not proved by a tagged test.

Ian's launch post also describes mix covenant.check for contract coverage, decision records with checkable conditions, and mix covenant.mutate, which runs mutation testing and credits results to individual obligations.

The only source is a single X post by Ian, so the release details and feature descriptions come from his own account and have not been independently verified.
