这些指标是进入带帧率压测前的关键保护栏：如果 `queue_depth` 持续增长或 `enqueue_total{status="timeout"}` 增长，说明入口 publish 队列已成为瓶颈。
### Gateway frame duration histogram
2026-07-03 已为 Gateway 帧处理耗时增加 histogram：
```text
vehicle_gateway_frame_duration_ms_histogram_bucket{protocol,status,le}
vehicle_gateway_frame_duration_ms_histogram_count{protocol,status}
vehicle_gateway_frame_duration_ms_histogram_sum{protocol,status}
```
该耗时覆盖单帧从解析、identity resolve、parsed fields 生成、publish enqueue 到协议响应写入的整体入口处理路径。带帧率压测时用它按协议观察 p95/p99，不能只看 `vehicle_gateway_frame_duration_ms` 最后一条 gauge。
