Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# internal/memory — rollout 账本与重放读侧

> 范围：本目录内不可派生的约束。全局见仓库根 `AGENTS.md` §6.7。

## 边界

rollout JSONL 的**唯一写入者与唯一事实来源**：`/resume`、检查点、重放都只读它。
只管"会话账本"：不管压缩策略、不管委派编排、不判断业务对错。
仓库级持久知识不在这里（那是 `internal/blueprint`）——顺带住在这里的 KV 存储
（`SharedMemory` / `LocalMemory`）已于 2026-10-22 随知识整理机制一并删除。
任务记忆 `~/.yagent/tasks/*.jsonl` 在 `internal/datamanager`，**不是**断点续跑的事实来源。

## 硬约束

**1. 检查点指纹只能由读侧计算**（`rollout_checkpoint.go:93-104`）。写侧必须调用与重放端同一个
`FinalizeCheckpoint`，对**整份文件重建出的**消息序列算 sha256。按内存里那份算的后果：任何触发过
压缩的会话（=每一个长任务）都会在自己的检查点上对不上号，B 层恰好死在它最该起作用的地方。
`Reasoning` 必须算进指纹（`:35-37`，thinking 要回灌给 provider，漏算不是"少几个 token"而是
"整次重放被判成不可信"）；`IsAnchored` / `TruncationMarker` 刻意不在（`:38-40`）。

**2. 读自己写过的文件之前必须先排干。** 落盘是攒批的（32 条 / 20ms，`rollout_writer.go:45-46`）。
自己拼 `Flush + FinalizeCheckpoint(path)` 的调用点一定会拿到"少几条"的指纹——它不报错，
只是把能重放的会话判成损坏（`rollout_checkpoint.go:124-143`、`rollout_writer.go:286-291`）。

**3. `ConversationMemory.messages` 不导出，读写只走方法**：`Snapshot()` 拿拷贝、
`Append`/`Add*` 写、`Replace` 整体装载（不触发 MaxSize 截断）、`LastMessage()` 返回**拷贝**
（`memory.go:62-70`）。注释给出的三条理由：并发注入跑在工作线程上（planner 在主线程写同一份）；
留一个导出字段就等于承诺"锁保护一切"，而改之前它有 31 处包外直接读写、`datamanager` 甚至会 append；

How to install

The exact contents, by fingerprint

mdr add iohub/yagent/internal/memory/AGENTS.md@sha256:ff0847e08822dea4

The line at the top of this page pins the label git:20261024.9b44441, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
