-## ADR-001  MQ 选型：Kafka
+## ADR-001  消息通道：Kafka
 - **Status**: Accepted
 - **Context**: 需要高吞吐、严格单车有序、成熟生态
 - **Decision**: 使用 Kafka，分区 key = VIN
-- **Consequences**: 下游消费者需使用消费组 + 分区内顺序消费；不使用 RocketMQ 的事务/顺序特性
+- **Consequences**: 下游消费者需使用消费组 + 分区内顺序消费；生产链路只支持 Kafka。
 
 ## ADR-002  线上消息格式：Protobuf
 - **Status**: Accepted

 `TDENGINE_MIN_IDLE=0` 用于减少冷启动时 TDengine 连接重试日志。TDengine 地址稳定后，再按生产并发调大连接池。
 
-高吞吐生产验收默认关闭 `EVENT_FILE_STORE_ENABLED` 和 `TDENGINE_TELEMETRY_FIELDS_ENABLED`，验证 TDengine `raw_frames`、位置表和分页查询闭环。RAW 帧的 `parsedJson`、`metadataJson`、`rawUri` 直接进入 TDengine，GB32960 snapshot/fields 接口优先基于 `raw_frames` 中的结构化 JSON 返回结果；接入服务写出的原始 `.bin` 只作为冷备复核材料。需要兼容旧 `/api/event-history/records` 低层记录接口或逐字段趋势宽表时，再显式开启对应开关，并单独压测写入放大。
