Part 5 of 6: The Regulation That Cannot See the Bias It Was Built to Catch.

TL;DR: The EU AI Act's high-risk provisions take effect August 2026. Your multi-agent pipeline is covered. But the regulation doesn't define "bias," doesn't require population-level testing, and can't audit emergent behaviour. You can pass every compliance check and still have every problem from Parts 1 through 4.

Catch up: Part 1 biased judge. Part 2 upgrading made it worse. Part 3 population drifted. Part 4 one adversarial agent flipped the swarm.
