list_routers grades every router as the Traefik page does (the last 15 minutes, 5xx on its cutoff, 4xx and p95 against the router's normal) and gives a troubled one its status codes, what they mean and the swarm service behind it. get_router adds its history, codes, normal and anomalies; list_certificates the served certificates and the routers they cover; get_traffic the access log's clients, countries and routers. get_overview names a router answering 5xx and a certificate near expiry. The access-log aggregation moves into routes.summarize_access, shared by the traffic page and get_traffic. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
