+When `report_url` is set, evicted proxies are POSTed to the upstream API
+after each health test cycle. This helps the source maintain list quality.

+## Hot Reload
+
+Send `SIGHUP` to reload the config file without restarting:
+
+```bash
+kill -HUP $(pidof s5p)
+# or in a container:
+podman kill --signal HUP s5p
+```
+
+Settings reloaded on SIGHUP:
+
+| Setting | Effect |
+|---------|--------|
+| `timeout` | Per-connection timeout |
+| `retries` | Max retry attempts |
+| `log_level` | Logging verbosity |
+| `proxy_pool.*` | Sources, intervals, thresholds |
+
+Settings that require a restart: `listen`, `chain`.
+
+Requires `-c` / `--config` to know which file to re-read. Without a
+config file, SIGHUP is ignored with a warning.
