# Context & Memory Management(C 层)
|
||||
|
||||
> ETCLOVG 的 C 层:控制模型在短期、会话级和持久视野中能看到什么。从 Prompt Engineering 演进而来。
|
||||
|
||||
## 三层视野
|
||||
|
||||
- **短期(Active Context Window)**:compaction、tool-result clearing、prompt-cache-aware ordering
|
||||
- **中期(Session State)**:跨运行持久化、会话状态管理
|
||||
- **长期(Persistent Memory)**:向量存储、知识图谱、写入-管理-读取循环
|
||||
|
||||
## 核心挑战:上下文漂移(Context Drift)
|
||||
|
||||
最深的上下文问题不是装更多 token,而是保持 Agent 的**工作状态与真实任务状态对齐**。
|
||||
|
||||
每次压缩、检索、遗忘操作都可能删除约束、扭曲优先级或保留过时假设。
|
||||
|
||||
## 重新框架:上下文作为状态估计
|
||||
|
||||
Zhang et al. (2025) 和 Du (2026) 将 Agent 记忆形式化为**写入-管理-读取循环**。未来系统需要:
|
||||
- 不确定性感知摘要
|
||||
- 事实溯源(provenance)
|
||||
- 矛盾处理
|
||||
- 显式陈旧标记
|
||||
- 从持久化产物重建状态的恢复程序
|
||||
|
||||
## 相关概念
|
||||
|
||||
- [[context-state-estimation]] — 上下文作为状态估计
|
||||
- [[reliable-state-long-running-agents]] — 长期状态维护
|
||||
- [[prompt-to-harness-evolution]] — 从 Prompt 到 Context 的演进
