       "description": "Browser console shows: api/admin/logs/stream:1 ERR_NETWORK_IO_SUSPENDED. The Next.js catch-all proxy in apps/admin/src/app/api/[...path]/route.ts streams the SSE response correctly, but the SSE connection appears to drop on the client side. Probable causes: (a) proxy doesn't forward Connection: keep-alive correctly, (b) admin frontend doesn't reconnect on drop, (c) backend SSE endpoint closes on idle. Triage: inspect proxy headers + frontend EventSource usage, add reconnect logic, ensure backend sends keep-alive comments.",
