Agents
Every agent Botscent can name: its vendor, its name in a verdict, and the evidence that names it.
Each row is one agent_name value. The Evidence column lists the reasons or declarations that name the agent.
Named agents: 100, from the registry. Software the registry does not name, such as a browser under automation, is still reported as an agent, without a name.
