Pay attention to this one, AI devs, especially if you're thinking about agentic commerce or any agent network where many agents share hosts. A correct route to a cold agent is still a failed request from the user's perspective. That's the whole game. This new paper studies decentralized agent discovery under two-level churn: node-level (failures, joins, recoveries) and agent-level (warm/cold lifecycles, demand-driven activation). They compare Kademlia, the indexing substrate behind AGNTCY, against a Cyclon+Vicinity gossip overlay, and introduce a useful-availability metric that captures whether a discovered agent can actually serve within a deadline, not just whether it's reachable. Structured overlays win on routing efficiency and lookup latency in stable and node-churn regimes. But under aggressive agent cooling, gossip can flip to better service usability despite higher messaging overhead. The reframe is from "which overlay is faster" to "under which regime does robustness convert into usability." That distinction will matter the moment agent networks start running at production scale.
