openspec/changes/fix-uint64-overflow/tasks.md

## 1. Implementation
- [x] 1.1 Update `heartbeatProcessor.js` to handle all numeric overflow types (`int16`, `int32`, `int64`) with two's complement.
- [x] 1.2 Prevent purely data-related Postgres failures from throwing away individual fallbacks within `databaseManager.js`.
- [x] 1.3 Add `insertHeartbeatEventsErrors` to `databaseManager.js` to sink rejected records.
- [x] 1.4 Wire `_emitRejectedRecord` in `heartbeatProcessor.js` to directly write all completely unprocessable heartbeats into the `heartbeat_events_errors` DB.
- [x] 1.5 Update the `openspec` specs with these newly supported overflow & validation fallback states.
feat: 处理整数溢出并持久化无法处理的数据 - 更新 heartbeatProcessor.js 以处理所有数字溢出类型（int16、int32、int64）并使用二进制补码。 - 防止仅与数据相关的 PostgreSQL 失败抛出个别回退错误。 - 在 databaseManager.js 中添加 insertHeartbeatEventsErrors 方法以存储被拒绝的记录。 - 更新 heartbeatProcessor.js 中的 _emitRejectedRecord 方法，直接将所有无法处理的心跳数据写入 heartbeat_events_errors 数据库。 - 更新 openspec 规范以支持新的溢出和验证回退状态。 - 添加测试文件以验证大整数处理。 2026-03-02 10:49:02 +08:00			`## 1.
