+# 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。

+# Spec Delta: onoffline-backend
+
+## MODIFIED Requirements
+
+### Requirement: 数据库分区策略
+系统 SHALL 使用 Range Partitioning 按天分区，并自动维护未来 30 天的分区表，子表依赖 PostgreSQL 原生机制继承主表索引。
+
+#### Scenario: 分区预创建
+- **GIVEN** 系统启动或每日凌晨
+- **WHEN** 运行分区维护任务
+- **THEN** 确保数据库中存在未来 30 天的分区表，无需对子表显式创建单列表索引

+- [x] refactor `src/db/partitionManager.js`: remove `ensurePartitionIndexes` and `ensureIndexesForExistingPartitions`.
+- [x] refactor `src/db/partitionManager.js`: update `ensurePartitions` and `ensurePartitionsForTimestamps` to remove calls to `ensurePartitionIndexes`.
+- [x] refactor `src/db/initializer.js` (and any other occurrences) to reflect the removal.
+- [x] update openspec requirements to clarify that index propagation relies on PostgreSQL parent-table indexes.
