What it is not
Not a replay suite. Keep Braintrust or LangSmith. Bad Day exports curveballs into them.
Not sandbox mode. Sandbox logs one clean path. Bad Day makes the path dirty.
Not a certificate. The report says what was tested, what was not, and what came back inconclusive.
Send the last change. We write five curveballs and the rules we would check, before you connect anything.
