AdCampaigner is a self-improving ad-campaign agent team that has to prove every change before keeping it. Most agent teams perform the same on run 100 as on run 1, and the ones that "learn" can quietly get worse, especially in advertising, where platform-reported conversions over-credit retargeting and brand search.
