I'm at the races is a local developer tool that hunts front end race conditions on purpose.  The correct responses arriving in the wrong order can silently corrupt balances, totals, search results and prices, and happy path tests miss the fault because each response alone is correct.  A Muse Spark agent reads the repo, designs a timing experiment, runs it in a real browser, holding responses back and releasing them late.  If the screen ends up wrong then an executable assertion proves it and that failure is frozen as a regression test.  The tool then writes a patch in an isolated git checkout and verifies it.  Shown working on two purpose built fixtures and on an external 1.8k star React app.
