AI agents often say “done” as soon as the tests pass, but the tests can have blind spots. Traceback is my answer to that for the Done Means Done track. You give it a one-line goal, and it writes a test that has to fail on the broken code before it’s allowed to fix anything. After the fix, it deliberately breaks its own fix in small ways to see if the tests notice, and if one slips through, another agent writes a new test to cover it. The final say always comes from real test results, not from the AI, so the report says “Verified within scope” instead of “fixed” and lists what it couldn’t check. The pricing project it runs on is a small open-source sample I published the day before; everything else was built today.
