Even at the highest risk tier, halt latency does not reach machine speed.
35,398 AI agents in the substrate are flagged as EU AI Act high-risk by attribute match. 13.05 percent of these have a halt mechanism with sub-minute latency. 57.72 percent are at manual or unknown latency. Among the remaining 60,478 agents in the substrate, sub-minute coverage drops to 6.41 percent. The risk tier moves the needle, but not across the threshold.
The two bars show the latency distribution of halt mechanisms for two cohorts: agents flagged as EU AI Act high-risk (top, n=35,398) and the remaining agents (bottom, n=60,478). Each segment is sized by the share of agents at that latency. The dashed gold line marks the sub-minute threshold. High-risk agents do receive more attention. Sub-minute halt coverage is twice as high. But more than half remain at manual or unknown latency. The risk classification moves resources, not the threshold.
