AI coding agents love to say “Done, all tests pass.” I’ve spent five years building finance integrations, where code that looks done but isn’t moves real money the wrong way. So I don’t trust “done.” I verify it.

MergeGuard is a referee between Meta’s Muse Code and your main branch. It re-runs the real tests in a clean worktree and catches the classic cheats: deleted, skipped or edited tests, stubs, and fake passes. Then Muse Spark reads the agent’s own session log and checks every claim it made: verified, false, or no evidence. If something’s wrong, MergeGuard sends it back to Muse Code to fix and checks again. Risky changes, like an auth bypass, go to a human.

One rule: real tests decide, not the AI. The AI can add a block, never remove one.

Built solo in one day, mostly by Muse Code itself.
