 本目录用于把本机 32960/JT808/history 三个服务的启动方式仓库化。模板面向当前生产验证链路：
 
 - `gb32960-ingest-app`: TCP `32960`，HTTP `20100`
-- `jt808-ingest-app`: TCP `808`，HTTP `20482`
+- `jt808-ingest-app`: TCP `808`，HTTP `20400`
 - `vehicle-history-app`: HTTP `20200`
 
 `vehicle-history-app` 的热历史查询只依赖 Kafka 与 TDengine：RAW 帧的 `parsedJson`、`metadataJson`、`rawUri` 已进入 TDengine `raw_frames`。GB32960/JT808 接入服务可以继续保留 `SINK_ARCHIVE_PATH` 作为原始 `.bin` 冷备，history 本机模板不再要求共享 archive root。
