+## Why
+当前双写仅写入 onoffline_record_g5，未同步更新 G5 状态表 `room_status.room_status_moment_g5` 的 `ip` 字段，导致状态表与最新上报数据存在延迟。

+# Proposal: Refactor Partition Indexes
+
+## Goal
+利用 PostgreSQL 默认的支持，改变每日分区创立时的索引策略，不再在代码中对每个分区单独创建索引。
+
+## Context
+当前 `PartitionManager` 在动态创建子分区后，会隐式调用查询在子分区上创建六个单列索引。由于我们使用的是 PostgreSQL 11+，且我们在初始化脚本中的主分区表 `onoffline.onoffline_record` 上已经创建了所有的索引，此主表上的索引会自动应用于所有的子分区，不需要我们在创建分区时另外手动添加。
+
+## Proposed Changes
+1. 在 `src/db/partitionManager.js` 中移除子分区显式创建索引的方法 `ensurePartitionIndexes` 以及针对已有子分区的循环索引检查函数 `ensureIndexesForExistingPartitions`。
+2. 在更新分区流程 `ensurePartitions` 以及 `ensurePartitionsForTimestamps` 中，移除对 `ensurePartitionIndexes` 的调用。

+# Change: remove runtime db provisioning
+
+## Why
+当前服务在运行时承担了建库、建表和分区维护职责，导致服务职责边界不清晰，也会引入启动阶段 DDL 风险。现已将该能力剥离到根目录 `SQL_Script/`，需要通过 OpenSpec 正式记录为规范变更。
+
+## What Changes
+- 移除服务启动阶段的数据库初始化与定时分区维护要求。
+- 移除服务在写入失败时自动创建缺失分区的要求。
+- 明确数据库结构与分区维护由外部脚本（`SQL_Script/`）负责。
+- 保留服务的核心职责：Kafka 消费、解析、写库、重试与监控。

+## 1. Implementation
+- [x] 1.1 Update Kafka row building logic to preserve `restart` as a valid `current_status` value.
+- [x] 1.2 Update G5 database mapping so `restart` maps to `3`.
+- [x] 1.3 Update processor tests for the `restart` case.
+- [x] 1.4 Update OpenSpec requirements for supported current status values.
+
+## 2. Validation
+- [x] 2.1 Run `npm run test`.
+- [x] 2.2 Run `npm run build`.
+- [x] 2.3 Run `openspec validate add-restart-current-status-mapping --strict`.
