+| `listener_latency` | object | Per-listener latency, keyed by `host:port` |
+
+### Per-listener latency
+
+Each listener tracks chain setup latency independently. The `/status`
+endpoint includes a `latency` field on each listener entry:
+
+```json
+{
+  "listeners": [
+    {
+      "listen": "0.0.0.0:1080",
+      "chain": ["socks5://10.200.1.13:9050"],
+      "pool_hops": 2,
+      "latency": {"count": 500, "p50": 1800.2, "p95": 8200.1, "...": "..."}
+    }
+  ]
+}
+```
+
+The aggregate `latency` in `/metrics` combines all listeners. Use
+`listener_latency` or the per-listener `latency` in `/status` to
+isolate latency by chain depth.
