From 6a404e92caa7054a11c42bee41396ea00f3d6b1b Mon Sep 17 00:00:00 2001 From: jack Date: Sat, 4 Jul 2026 17:46:41 +0800 Subject: [PATCH 1/4] feat(memory): cross-session learned memory (file-based, git-backed, BYOM-aware) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a three-layer agent memory system so jcode learns durable facts from past sessions and feeds them into future ones: - L0 AGENTS.md (unchanged) — static, human-authored instructions. - L1 online notes — the `memory_note` tool writes one durable fact to a per-project inbox instantly (path-locked + secret redaction). - L2 offline distillation — phase 1 extracts per-ended-session facts with the small model; phase 2 consolidates via a restricted subagent, git-diff driven with a zero-token no-op fast path and an ADD/UPDATE/DELETE/NOOP protocol. The read path injects a size-capped memory summary into the system prompt (TUI/ACP/web + plan mode); usage accounting feeds consolidation ranking. No SQLite — state.json + flock, and the memory root is a git repo used for change detection, forgetting, and rollback. BYOM cost discipline: a daily token budget spanning both phases, a cooldown, small-model default, and a kill switch. Storage mirrors Claude Code/Codex: global ~/.jcode/memory/, scoped per project. Config: config.Memory{...} with zero-config defaults. CLI `jcode memory {path,status,sync,clear}`; TUI `/memory`. e2e: agent-eval is extended with multi-step runs, HOME fixtures/config, and home_* oracles, plus a `memory` tier (9 cases, 9/9 pass on glm-5.1). Unit tests cover redaction, the path guard, concurrency, UTF-8 truncation, and the git no-op fast path. Docs: site/docs/overview/learned-memory.md plus config/commands cross-links. Design + research live in internal-doc/agent-memory-{design,e2e-plan}.md and memory-research-2026-07.md. Reviewed adversarially across 5 dimensions; fixes include git churn breaking the no-op fast path, phase-2 budget/cooldown gaps, a broken usage-feedback loop, a WriteNote concurrency race, redaction gaps, and UTF-8-safe truncation.

pipeline**（`codex-rs/memories/{read,write}` + `ext/memories`，两阶段蒸馏 + git 遗忘）与 Claude Code 的 **file-based memory**（MEMORY.md 索引 + **每主题一文件** + 在线写入 + 未发布的离线整合层 auto-dream）。 +> 关联：[[jcode internal doc convention]]、[[jcode subagents]]、[[jcode browser use]]（同为"对标后收敛"方法论）。 +> 范围声明：本文只讨论**跨会话的习得式长期记忆**。AGENTS.md（静态指令）与 compaction（会话内摘要）不在重构范围，但要与之划清边界（§2.1）。 + +--- + +## 0. v1.1 修订记录（deep-research 对抗验证后） + +全部锚定 primary source（3-0 验证通过）： + +1. **事实修正**：Claude Code auto memory 存储在 `~/.claude/projects//memory/`，按 git 仓库为键（worktree 共享），形态是 **MEMORY.md 索引 + 每主题一文件**（非"每事实一文件"）；启动只注入 MEMORY.md 前 200 行或 25KB，主题文件按需读。精编层按主题/任务族组织，收件箱保持单事实小文件。 +2. **双层收敛得到验证**：Claude Code 写入并非纯在线——存在四阶段离线整合（auto-dream：Orient → Gather Signal → Consolidate → Prune & Index，Stop hook 24h 去抖）。两大厂都落在"在线写 + 离线整合"双层，jcode 的 L1 收件箱 + L2 蒸馏架构正处收敛点。 +3. **整合协议化（借 Mem0）**：Phase 2 整合代理对每条输入显式输出 ADD/UPDATE/DELETE/NOOP 决策，把自由文本整合变成可断言、可统计 no-op 率的协议（直接服务 M2/M3 验收）。遗忘在写入时由矛盾驱动（DELETE），不只靠时间衰减。 +4. **整合 prompt 三细则（借 dream-skill）**：相对日期转绝对日期、矛盾消解、清理指向不存在文件的引用；MEMORY.md 重建为 ≤200 行的精简索引，冗长条目降级为主题文件。 +5. **安全补齐（借 Anthropic memory tool 官方清单）**：memory 单文件大小上限；超大文件分页读取；路径校验覆盖 URL 编码穿越变体（canonical 化后再前缀比对；同类攻击真实存在，CVE-2025-53110/53109）；基于访问时间的过期与 §3.2 usage 记账天然合一。 +6. **Codex 细节限定**：其存储实为 state DB + 文件混合（Phase 1 输出先入 DB，Phase 2 才同步 top-N 到文件工作区）；jcode 用 state.json + flock 替代是正确的无 SQLite 等价物。另外 GitHub issues 证实 Codex 后台记忆生成消耗用户配额，印证 BYOM 预算闸门（洞察三）的必要性。 +7. **实现层勘误（代码摸底）**：leader 会话文件是 `~/.jcode/sessions/{uuid}.json`（teammate 才是 `.jsonl`）；审批中间件层只能看到工具名 + 序列化参数，§3.2 的 usage 记账需从 argumentsInJSON 提取路径（纯 Go 字符串处理，不依赖模型配合，方向不变）。 +8. **eino 调研**：见文末 §11（单独补查）。 + +--- + +## 1. 一句话定义与背景 + +**Agent Memory = 让 jcode 从历史会话中自动蒸馏"用户偏好 / 项目事实 / 失败教训 / 可复用流程"，以文件形式存放、以渐进披露方式注入未来会话，并通过使用反馈与保留窗口实现遗忘。** + +### 1.1 jcode 现状：只有"静态记忆"，没有"习得记忆" + +| 现有机制 | 位置 | 性质 | 缺口 | +|---|---|---|---| +| AGENTS.md 三级合并（global/project/local，`@include`，40k 字符上限） |

先对齐：两个参考代表两种哲学，jcode 取交集 + +逐行读过 Codex 的 memory 实现（`codex-rs/memories/README.md` + `write/src/{start,phase1,phase2}.rs` + 三份 prompt 模板 + `state/memory_migrations/0001_memories.sql`）和 Claude Code 的

**核心洞察一：两派的存储形态已经收敛——"文件夹 + markdown + 索引文件 + 渐进披露"是共识**，分歧只在"谁在什么时候写"。文件形态对 jcode 尤其合适：用户可 cat/编辑/删除，可 git 管理，零新依赖。 +> +> **核心洞察二：Codex 最精巧的两个机制是 git-as-change-detector 和 usage 反馈闭环。** 整合前先对 memory 目录做 git diff，无变化直接退出（一个 token 不花）；被引用的记忆 usage_count++，下次整合排名更高、更不容易被淘汰。这两个机制实现成本低、收益极高，jcode 必须抄。 +> +> **核心洞察三：jcode 是 BYOM（用户自付 API 账单），不能照抄 Codex 的"每次启动都跑管线"。** Codex 背后是订阅制配额，烧 token 无感；jcode 用户看得见每一分钱。所以写路径必须：默认用 SmallModel、带每日 token 预算闸门、冷却窗口去抖、可一键关闭。 +> +> **核心洞察四：Claude Code 的在线笔记派解决了 Codex 的"记忆延迟"问题**（Codex 的记忆最快也要下次启动才出现），但依赖模型自觉，BYOM 场景下杂牌模型的写入纪律不可靠。解法：在线写入只进**收件箱**（inbox），不直接改精编文件——把"廉价快速但低质"和"昂贵缓慢但精编"解耦。 + +### 1.3 jcode 底座现状（交叉验证自源码） + +- **会话存档**：leader 会话 `~/.jcode/sessions/{uuid}.json`，teammate 在 `sessions/{leaderUUID}/subagents/agent-{id}.jsonl`（`internal/session/session.go:480`）；索引 `sessionIndex.Sessions` 按 project path 分组，`SessionMeta` 含 `end_time/terminal_status/error_reason`——Phase 1

一个工具受限、cwd 锁定的 subagent，不新建执行机制。 +- **注入点**：`internal/prompts/prompts.go:22` `GetSystemPrompt` 已经在拼装 AGENTS.md / skills 描述，memory summary 作为新的一段加入即可。 +- **工具注册**：`buildAllTools()`（`internal/command/web.go`）+ 审批中间件，新增 `memory_note` 工具走同一注册点。 +- **无 DB**：jcode 全程 JSON 文件 + atomic rename（`session.go:604` 有明确的并发注释）。**不引入 SQLite**（cgo 或纯 Go 实现都太重），协调状态用 `state.json` + `flock` 文件锁，量级完全够（记忆条目 = 千级）。 +- **后台任务先例**：`internal/automation/store.go` 已有定时任务基建，可作为管线的第二触发通道。 +- **命名冲突提醒**：`internal/prompts/memory.go` 现在的 "MemoryLoader" 实为 AGENTS.md 加载器。落地时建议改名 `InstructionsLoader`（保持 json 兼容），"memory" 一词让位给本系统，避免长期混淆。 + +--- + +## 2. 总体设计：三层记忆 + +``` +┌─ L0 静态指令（现状保留）────────────────────────────────┐ +│ AGENTS.md 三级合并 — 用户手写，权威，永不被机器改写 │ +├─ L1 在线笔记（借

作用域：项目优先，全局兜底 + +Codex 是全局记忆 + cwd 标签路由；Claude Code 是纯项目级目录。jcode 的会话索引天然按 project path 分组，取两者之长： + +``` +~/.jcode/memory/ +├── global/ # 跨项目的用户画像与通用偏好 +│ ├── MEMORY.md +│ └── memory_summary.md +└── projects/-/ # 每项目一个根（slug 取路径尾段，hash 防碰撞） + ├── memory_summary.md # ① 常驻 prompt（token 截断，默认 ≤1200 tokens） + ├── MEMORY.md # ② 可 grep 的手册（按任务族分块） + ├── notes/ # ③ L1 收件箱（-.md，单事实小文件） + ├──

+``` + +设计要点： + +- **项目记忆和全局记忆分开整合、分开注入**。项目 summary 注入量大头，全局画像限 ≤300 tokens。 +- **memory 根是 git 仓库**（`git init` 一次，jcode 每次成功整合后 commit 作为 baseline）。收益三个：变更检测（无 diff 不跑整合代理）、遗忘信号（删除文件体现在 diff 里，整合代理据此清理 MEMORY.md）、用户可 `git log` 审计记忆演变、误删可回滚。 +- **state.json 替代 Codex 的 SQLite**：`{"jobs": {...租约/重试...}, "extracted": {"": {"at":..., "summary_file":..., "usage_count":0, "last_usage":null}}, "budget": {"2026-07-04": 83000}}`。写入走 flock + atomic rename，与 `session.go` 现有模式一致。 + +--- + +## 3. 读路径 + +### 3.1 注入（对标 Codex read_path.md，大幅精简） + +`GetSystemPrompt` 拼装时，若 `memory_summary.md` 存在且非空，渲染注入模板（新增 `internal/prompts/templates/memory_read.md`），内容包含： + +1. **决策边界**：什么时候查记忆（任务涉及本项目历史/约定/此前决策）、什么时候跳过（自包含小任务）——直接借鉴 Codex 的 hard-skip 例子。 +2. **目录地图**：summary（已在下方，勿重读）→ MEMORY.md（grep 首选）→ notes/ 与 session_summaries/（按需开 1-2 个）。 +3. **检索预算**：≤4 步检索后必须开始正事（BYOM 更要抠 token）。 +4. **陈旧性纪律**：凡引用未经本轮验证的记忆事实，须注明"来自记忆，可能过期"；易漂移且验证便宜的事实先验证再用。 +5. **MEMORY_SUMMARY 正文**（token 截断）。 + +> 注意与 Codex 的取舍差异：**不要求模型输出 `` 结构化引用块**。那是 Codex 对自家模型的合规性有把握才敢做的；BYOM 杂牌模型输出格式不可靠，且引用块会泄漏到用户可见回复里。usage 反馈改走 §3.2 的零合规通道。 + +### 3.2 使用反馈（零模型合规成本） + +对标 Codex `memories/read/src/usage.rs` 的**命令解析**通道：在工具执行层（审批中间件同层，`internal/agent/middleware.go`）观察 read/grep/bash-安全读命令的目标路径，凡命中 `~/.jcode/memory/` 下的文件即记账： + +- `state.json` 中该文件对应条目 `usage_count++`、`last_usage=now`； +- 命中 `session_summaries/.md` 的同时给其源会话的 extracted 记录记账（Phase 2 排名用）。 + +这条通道不需要模型配合、不污染回复、实现是纯 Go 字符串匹配。实现注意（代码摸底勘误）：`WrapInvokableToolCall` 中间件只拿得到 `tCtx.Name` + `argumentsInJSON`，路径需从 JSON 参数（`file_path`/`path`/`pattern`/`command`）解析提取后再做前缀匹配；grep 走的目录参数同理。citation 引用块留作 v2 可选增强（对已验证合规的模型开启）。 + +### 3.3 检索工具 + +不新增专用检索工具。jcode 的 grep/read 工具已覆盖需求（Codex 也默认走 shell 检索，dedicated_tools 是可选项）。memory 目录默认加入工具的可读白名单、免审批（只读）。 + +--- + +## 4. 写路径 L1：在线笔记（收件箱模式) + +新增工具 `memory_note`（注册进 `buildAllTools()`）： + +``` +memory_note(scope: "project"|"global", kind: "preference"|"fact"|"pitfall"|"workflow", text: string) +→ 写入 /notes/-.md（含 frontmatter: kind/source/session_id/cwd） +``` + +规则（写进工具描述 + system prompt）： + +- **写入门槛**照抄 Claude Code 的纪律：只记"会改变未来默认行为的耐久事实"；repo 里已有的（代码结构、git 历史、AGENTS.md 内容）不记；只对本会话有意义的不记。 +- **用户显式要求"记住 X"** → 必须调用此工具（source=user，整合时权重最高），这是 Codex ad_hoc extension 的等价物。 +- 笔记**只进收件箱**，不直接改 MEMORY.md/summary——精编文件只由 Phase 2 整合代理维护，保证格式与去重质量。 +- 写入前过一遍**脱敏正则**（API key/token/密码模式 → `[REDACTED]`），与 §6.1 共用。 +- 免审批（写入范围锁死在 memory 根内，由工具实现保证，非依赖模型自觉）。 + +读路径会同时 grep notes/，所以在线笔记**立刻可用**，不等整合——这补上了 Codex"记忆要等下次启动"的延迟短板。 + +--- + +## 5. 写路径 L2：离线蒸馏管线 + +### 5.1 触发与守卫（对标 codex start.rs 的门条件） + +主触发：会话提交首个用户 turn 后 `go func()` 异步启动（不阻塞交互）。逐项检查： + +``` +memory.enabled？ → 非 subagent/teammate 会话？ → 非一次性(-p/print)模式？ +→ 冷却期已过（上次成功整合 < cooldown_hours 前）？ → 今日 token 预算未超？ +→ flock 拿到管线锁？ → 全过才跑 +``` + +副触发：`jcode memory sync` 手动命令 + automation 定时任务（夜间跑，白天会话零开销——这是 Codex 没有而 jcode 凭 `internal/automation` 基建能白拿的形态）。 + +**预算闸门**（洞察三的落地）：`state.json.budget` 按天记账管线消耗的 token（从模型响应 usage 字段累加），超过 `memory.daily_token_budget`（默认 300k）当日直接跳过。这是对 Codex rate-limit guard 的 BYOM 化替代。 + +### 5.2 Phase 1：逐会话提取 + +选材（复用 `sessionIndex` + `SessionMeta`，规则对标 Codex startup claim）： + +- 本项目的、已结束的（`end_time` 非空或文件 mtime 闲置 > 2h）、非 subagent 的会话； +- 尚未提取（不在 `state.json.extracted`）或源文件比上次提取新； +- 时间窗口内（默认 30 天）；每次启动限量（默认 ≤10 个，防首次启动雪崩）。 + +执行： + +- 并发 ≤4（Codex 用 8，BYOM 保守减半），模型用 `memory.model`（默认落到 `SmallModel`）； +- 输入 = 过滤后的会话 JSONL（去掉系统 prompt、工具原始大输出截断、**脱敏**），按模型窗口 70% 截断（抄 Codex 的 `CONTEXT_WINDOW_PERCENT`）； +- Prompt 直接移植 Codex `stage_one_system.md` 的骨架（这份 prompt 是其多轮迭代的精华，重点保留：**no-op 优先**、偏好信号 > 流程复述、用户消息权重 > 助手消息、任务分块 + outcome 标注、证据先于抽象）； +- 输出 JSON：`{summary, slug, memory}`，三空 = no-op；解析失败重试一次后记 `failed` + 退避（写进 state.json.jobs）； +- 成功 → `session_summaries/-.md` 落盘 + `state.json.extracted` 记账。 + +### 5.3 Phase 2：全局整合（受限子代理） + +1. flock 全局整合锁； +2. 选材：`extracted` 中按 `usage_count` 降序、`last_usage/at` 次序取 top-N（默认 40），淘汰超过 `max_unused_days`（默认 45）未被用过的——**usage 反馈在这里闭环**； +3. 同步工作区：落选的 summary 从磁盘删除、notes/ 收件箱全量纳入； +4. `git diff` 对比上次 baseline → 写 `workspace_diff.md`；**无 diff 则 commit-free 直接退出（零 token）**； +5. 有 diff → spawn 整合子代理（复用 subagent 运行器）： + - cwd = memory 根，工具白名单 = read/grep/write/edit（路径守卫锁死在 memory 根内），无 bash、无网络、无 MCP、禁止再 spawn、对它禁用 memory 注入（防递归）、全程免审批； + - Prompt 移植 Codex `consolidation.md` 骨架：INIT/INCREMENTAL 双模式、diff 是权威变更队列、删除的输入要触发 MEMORY.md 手术式清理、notes/ 消化后删除源文件、summary 首行版本标记（`v1`）不符则整体重建; + - **整合协议（借 Mem0）**：对每条收件箱笔记/新 summary，整合代理须显式输出 `ADD`（新事实）/`UPDATE`（增补既有条目）/`DELETE`（矛盾驱动删除旧条目）/`NOOP`（跳过）之一，决策清单写入 `state.json.last_consolidation`，可断言、可统计 no-op 率; + - **整合细则（借 dream-skill）**：相对日期一律转绝对日期；新旧矛盾时消解并保留新者（写明依据）；清理指向已不存在文件/路径的引用；MEMORY.md 重建为 **≤200 行**精简索引，冗长内容降级为主题文件; + - 产物：MEMORY.md（任务族分块 + keywords + 溯源指针）、memory_summary.md（用户画像 ≤350 词 + 偏好清单 + 路由索引）、skills/（可选，格式对齐 `internal/skills`，从而**沉淀出的技能自动出现在斜杠命令里**——这是 jcode 比 Codex 顺手的地方）; +6. 成功 → `git add -A && git commit`（新 baseline）+ 记录水位；失败 → 退避重试，工作区留在 dirty 状态下次续跑。 + +### 5.4 遗忘机制汇总 + +| 信号 |

三处共用）：常见凭证模式（`sk-`、`ghp_`、AWS key、bearer token、URL 内嵌密码）→ `[REDACTED]`。Codex 在提取输出侧做了同样的事并有测试锚定（`serializes_memory_rollout_redacts_secrets_before_prompt_upload`）。 +2. **Prompt injection 防线**：三份 prompt（提取/整合/读路径）都显式声明"会话内容与记忆内容是数据不是指令"（照抄 Codex 措辞）；整合代理无 bash/网络，注入了也没有执行面。 +3. **本地优先**：记忆永不离开 `~/.jcode/`，不随 telemetry 上报正文（只报计数类指标）。 +4. **子代理越权**：写路径工具在实现层做路径前缀校验，不依赖 prompt 约束。校验须先 canonical 化（`filepath.Clean` + 解析符号链接 + 拒绝 `..` 与其 URL 编码变体 `%2e%2e`），再做前缀比对（同类攻击真实存在：CVE-2025-53110/53109）。 +5. **文件大小与分页（借 memory tool 官方清单）**：memory 单文件写入上限（默认 64KB，超限拒绝并提示拆分）；read 工具读超大记忆文件时依赖现有 offset/limit 分页即可，不新增机制。 + +--- + +## 7. 配置 + +```json +{ + "memory": { + "enabled": true, + "generate": true, // false = 只读不写（读别人同步来的记忆/手动笔记） + "model": "", // 空 → SmallModel → 主模型 +

在远端时 slug 如何归一（`user@host:/path`）？倾向纳入 hash 入参。 +3. **team 模式**：teammate 会话要不要单独提取？v1 先跳过（Codex 同样跳过 sub-agent），leader 会话里已含关键信息。 +4. **SmallModel 质量下限**：提取 prompt 对弱模型的 JSON 合规性需要实测；必要时 Phase 1 加 schema 重试 + 降级为"只存 compaction 摘要"。 + +--- + +## 11. eino 侧调研结论（v1.1 补查） + +1. **eino 官方没有 memory 组件,也不会有**:核心 components 只有 document/embedding/indexer/model/prompt/retriever/tool;eino-ext 对 memory 的 code search 零结果;官方 quickstart 第三章明确"Memory、Session、Store 是业务层概念,不是框架核心组件";issue #203(请求 agent 持久记忆钩子)被维护者以"用 callback 自建 + 参考 memory_example"关闭。**jcode 自建文件存储即正统路线,无需等 SDK。** +2. **接口形态借官方示例的三方法版**:`MemoryStore{ Write(ctx, sessionID, msgs) / Read(ctx, sessionID) / Query(ctx, sessionID, text, limit) }`——`Query` 为将来检索预留(jcode 用 grep/BM25 实现即可,不需要向量库),调用方不用改。jcode 的 `internal/memory` 对外接口按此塑形（scope 取代 sessionID）。 +3. **瞬时注入、不入会话历史**(eino agentsmd 中间件的核心设计):记忆内容在模型调用时前插、永不写进 session state,天然免疫 compaction、不被摘要污染。jcode 经 GetSystemPrompt 注入 system prompt 等价满足;**切勿**把 memory 内容 append 进 history。 +4. 顺带发现(不属本特性,已记录):summarization 中间件的 TranscriptFilePath"摘要留原文指针"模式、reduction 的超长输出 offload+`ClearAtLeastTokens` 保 prompt cache、CheckPointStore 文件实现可解决 web

charset=UTF-8 Content-Transfer-Encoding: 8bit The .githooks/pre-commit existed but was never active (core.hooksPath unset), which is why the golangci-lint failure only surfaced in CI. Split into: - pre-commit: fast gofmt/goimports gate on staged Go files only (instant, keeps commits snappy). Portable to macOS's stock bash 3.2 (no mapfile). - pre-push: mirrors CI's Go job — go build, go vet, golangci-lint with the same --new-from-rev=origin/main gating (so pre-existing lint debt doesn't block), and go test. Runs once per push. Enable with `make setup-hooks`. Bypass a hook with --no-verify; skip only tests via SKIP_TESTS=1 git push.

The consolidated layer is organized by topic/task-family, while the inbox keeps single-fact small files. +2. **Two-layer convergence confirmed**: Claude Code's writes are not purely online — there is a four-phase offline consolidation (auto-dream: Orient → Gather Signal → Consolidate → Prune & Index, debounced 24h by a Stop hook). Both vendors land on "online write + offline consolidation" two layers, and jcode's L1 inbox + L2 distillation architecture sits right at that convergence point. +3. **Consolidation as a protocol (borrowed from Mem0)**: the Phase 2 consolidation agent emits an explicit ADD/UPDATE/DELETE/NOOP decision for each input, turning free-text consolidation into an assertable protocol with a measurable no-op rate (directly serving M2/M3 acceptance). Forgetting is driven at write time by contradictions (DELETE), not just time decay. +4. **Three consolidation-prompt rules (borrowed from dream-skill)**: convert relative dates to absolute dates, resolve contradictions, and clean up references pointing to nonexistent files; MEMORY.md is rebuilt into a lean index of ≤200 lines, with verbose entries demoted to topic files. +5. **Security gap-filling (borrowed from the official Anthropic memory tool checklist)**: a per-file size cap on memory; paginated reads for oversized files; path validation covering URL-encoded traversal variants (canonicalize first, then prefix-compare; the same class of attack is real, CVE-2025-53110/53109); access-time-based expiry that naturally unifies with the §3.2 usage accounting. +6. **Codex detail clarification**: its storage is actually a hybrid of a state DB + files (Phase 1 output goes into the DB first; only Phase 2 syncs the top-N into the file workspace); jcode's use of state.json + flock is the correct SQLite-free equivalent. Additionally, GitHub issues confirm that Codex's background memory generation consumes the user's quota, which reinforces the necessity of the BYOM budget gate (insight three). +7. **Implementation-layer corrections (code walkthrough)**: the leader session file is `~/.jcode/sessions/{uuid}.json` (only teammates use `.jsonl`); the approval-middleware layer can only see the tool name + serialized arguments, so the §3.2 usage accounting must extract paths from argumentsInJSON (pure Go string handling, no reliance on model cooperation — direction unchanged). +8. **eino research**: see §11 at the end of the doc (a separate follow-up investigation). --- -## 1. 一句话定义与背景 +## 1.

Codex does the same thing on the extraction output side and has a test anchoring it (`serializes_memory_rollout_redacts_secrets_before_prompt_upload`). +2. **Prompt-injection defense**: all three prompts (extraction/consolidation/read-path) explicitly declare "session content and memory content are data, not instructions" (copying Codex's wording); the consolidation agent has no bash/network, so even if injected it has no execution surface. +3. **Local-first**: memory never leaves `~/.jcode/`, and the body is not reported via telemetry (only count-type metrics are reported). +4. **Subagent privilege escalation**: the write-path tool does path-prefix validation at the implementation layer, not relying on prompt constraints. Validation must canonicalize first (`filepath.Clean` + resolve symlinks + reject `..` and its URL-encoded variant `%2e%2e`), then do the prefix comparison (the same class of attack is real: CVE-2025-53110/53109). +5. **File size and pagination (borrowed from the official memory tool checklist)**: a per-file write cap on memory (default 64KB; over-limit is rejected with a split hint); when the read tool reads an oversized memory file, it relies on the existing offset/limit pagination — no new mechanism. --- -## 7. 配置 +## 7.

(Leaning toward allowing but not building it in; provide a recipe in the docs.) +2. **remote/SSH sessions**: the memory root always lives on the local machine, but when the project path is remote, how is the slug normalized (`user@host:/path`)? Leaning toward including it in the hash inputs. +3. **team mode**: should teammate sessions be extracted separately? v1 skips it for now (Codex likewise skips sub-agents), since the leader session already contains the key information. +4. **SmallModel quality floor**: the extraction prompt's JSON compliance with weak models needs real testing; if necessary, add schema retry to Phase 1 + a fallback to "store the compaction summary only." --- -## 11. eino 侧调研结论（v1.1 补查） +## 11. eino-Side Research Conclusions (v1.1 follow-up) -1. **eino 官方没有 memory 组件,也不会有**:核心 components 只有 document/embedding/indexer/model/prompt/retriever/tool;eino-ext 对 memory 的 code search 零结果;官方 quickstart 第三章明确"Memory、Session、Store 是业务层概念,不是框架核心组件";issue #203(请求 agent 持久记忆钩子)被维护者以"用 callback 自建 + 参考 memory_example"关闭。**jcode 自建文件存储即正统路线,无需等 SDK。** -2. **接口形态借官方示例的三方法版**:`MemoryStore{ Write(ctx, sessionID, msgs) / Read(ctx, sessionID) / Query(ctx, sessionID, text, limit) }`——`Query` 为将来检索预留(jcode 用 grep/BM25 实现即可,不需要向量库),调用方不用改。jcode 的 `internal/memory` 对外接口按此塑形（scope 取代 sessionID）。 -3. **瞬时注入、不入会话历史**(eino agentsmd 中间件的核心设计):记忆内容在模型调用时前插、永不写进 session state,天然免疫 compaction、不被摘要污染。jcode 经 GetSystemPrompt 注入 system prompt 等价满足;**切勿**把 memory 内容 append 进 history。 -4. 顺带发现(不属本特性,已记录):summarization 中间件的 TranscriptFilePath"摘要留原文指针"模式、reduction 的超长输出 offload+`ClearAtLeastTokens` 保 prompt cache、CheckPointStore 文件实现可解决 web 审批跨进程恢复——可开后续任务。 +1. **eino officially has no memory component, and never will**: the core components are only document/embedding/indexer/model/prompt/retriever/tool; a code search of eino-ext for memory returns zero results; the official quickstart chapter 3 states explicitly that "Memory, Session, and Store are business-layer concepts, not framework core components"; issue #203 (requesting an agent persistent-memory hook) was closed by the maintainer with "build it yourself with callbacks + refer to memory_example." **jcode building its own file storage is the orthodox route, with no need to wait on the SDK.** +2. **Interface shape borrows the official example's three-method version**: `MemoryStore{ Write(ctx, sessionID, msgs) / Read(ctx, sessionID) / Query(ctx, sessionID, text, limit) }` — `Query` is reserved for future retrieval (jcode can implement it with grep/BM25, no vector DB needed), and callers do not have to change. jcode's `internal/memory` external interface is shaped after this (scope replaces sessionID). +3. **Transient injection, not entering the session history** (the core design of eino's agentsmd middleware): memory content is prepended at model-call time and never written into session state, naturally immune to compaction and not polluted by summarization. jcode's injection into the system prompt via GetSystemPrompt satisfies this equivalently; **never** append memory content into the history. +4. Incidental findings (not part of this feature, recorded): the summarization middleware's TranscriptFilePath "keep an original-text pointer in the summary" pattern, reduction's oversized-output offload + `ClearAtLeastTokens` to preserve the prompt cache, and the CheckPointStore file implementation that could solve web-approval cross-process recovery — all can spin off into follow-up tasks. -来源与本地源码核实详见 [[memory-research-2026-07]] 附录 A。 +Sources and local source-code verification are detailed in Appendix A of [[memory-research-2026-07]]. --- -## 12. 对抗审核与修复记录(v1.1,实现后) +## 12.

Fix: write a `.gitignore` at the scope root (state.json/*.lock/*.tmp), with an automatic `git rm --cached` migration for existing repos. (git.go, added regression test TestPhase2NoDiffAfterConsolidation + CLI end-to-end verification) +- **phase2 has no budget gate + failures don't write a cooldown → retry storm**: the consolidation agent bypasses the daily budget, and `LastPipelineAt` is only written on full success, so on failure it reruns at every session startup. Fix: move the budget gate up to `Run` to cover both phases + a second check after phase1; change `LastPipelineAt` to a deferred unconditional write (failure = enters cooldown = backoff).

Fix: `expireAndRank` joins back the real usage signal via `st.Files[SummaryFile]`. (phase2.go) +- **WriteNote same-second concurrency race**: TOCTOU + a shared `.tmp` → multiple parallel memory_note calls within one turn silently drop notes; Chinese text slugs degenerate to a fixed `note`. Fix: `O_CREATE|O_EXCL` atomic name claim + a unique tmp name (pid+counter); the slug retains CJK characters, falling back to a hash if empty. (note.go/memory.go, added concurrency test) +- **phase1 worker has no panic recover**: a worker goroutine's panic is not caught by the outer recover → crashes the whole process; `UUID[:8]` is a ready-made panic point. Fix: defer recover inside the worker + a `shortUUID` safe truncation. (phase1.go) +- **redaction hole**: JSON-quote-wrapped keys, URL passwords containing `/`, `github_pat_`, and `AWS_SECRET_ACCESS_KEY` all slipped through. Fix: add a JSON-quote rule + widen the URL-password character class + add github_pat_/broader key names. (redact.go, added test) +- **remote web task falsely triggers the pipeline**: an SSH/Docker task builds a local junk scope from the remote path and never matches a session. Fix: trigger only when `exec == nil` (local). (web.go) +- **token accounting only lands once at the end of run**: if the background goroutine dies with the process, already-spent tokens are not accounted. Fix: `bookTokens` incrementally right after each worker call + stop when the budget is exhausted (cap this round, not the next).

Fix: `firstJSONObject` balanced-brace scan (string-literal aware); phase2 parse errors now log instead of failing silently. (phase1.go/phase2.go, added test) +- **path guard doesn't block `.git/`**: an injected consolidation agent could write `.git/hooks/pre-commit`, executed at commit time.

The existing "one prompt turn per run" infrastructure is missing three things: -| 扩展 | 位置 | 设计 | +| Extension | Location | Design | |---|---|---| -| **多步 run(`steps`)** | orchestrate.py `run_one` | case 可给 `steps: [{"prompt": ...}, {"prompt": ...}, {"cli": ["memory","sync"]}]` 替代单 `prompt`。每个 prompt step 是一次全新 harness 进程(全新 ACP 会话),**共享同一 HOME + 同一沙箱 box**——这正是"跨会话"的建模。`cli` step 直接 `subprocess.run([bin, *args], env=HOME同上, cwd=box)`。逐 step 记录 result;`ctx["result"]` 取最后一个 prompt step 的,`ctx["step_results"]` 存全部。任一 step 崩溃即 run 失败。 | -| **HOME fixtures / 配置覆盖** | orchestrate.py `build_home` | case 可给 `home_fixtures: {"相对HOME路径": "内容"}`(如预埋 `.jcode/memory/projects//memory_summary.md`)与 `home_config: {...}`(浅合并进生成的 config.json,如 `{"memory": {"enabled": false}}`)。项目 slug 在 case 里用占位符 `{PROJECT_SLUG}`,orchestrate 按实现的 slug 规则(路径尾段-hash8)替换,hash 由 box 绝对路径算出。 | -| **HOME oracle 族** | verify.py + `ctx["home"]` | 新增 4 个 oracle,全部以 `$HOME`(rundir/home)为根解析,支持 glob:`home_glob_count {glob, min?, max?}`、`home_file_contains {glob, value}`(匹配到的**任一**文件含 value 即过)、`home_grep_absent {root_glob, pattern}`(正则,匹配到的所有文件都不得命中)、`home_file_exists {glob}` / `home_file_absent {glob}`。`run_one` 把 `rundir/home` 传入 ctx。 | -| **prune 保留证据** | orchestrate.py `_prune_home` | keep 集合加 `"memory"`(oracle 虽在 prune 前跑,但复盘需要留存)。 | +| **Multi-step run (`steps`)** | orchestrate.py `run_one` | A case may supply `steps: [{"prompt": ...}, {"prompt": ...}, {"cli": ["memory","sync"]}]` in place of a single `prompt`. Each prompt step is a brand-new harness process (a brand-new ACP session), **sharing the same HOME + the same sandbox box** — this is precisely how "cross-session" is modeled. A `cli` step runs `subprocess.run([bin, *args], env=same HOME, cwd=box)` directly. Record the result of each step; `ctx["result"]` takes the last prompt step's, and `ctx["step_results"]` holds all of them. Any step crash fails the run. | +| **HOME fixtures / config override** | orchestrate.py `build_home` | A case may supply `home_fixtures: {"path-relative-to-HOME": "content"}` (e.g. pre-seed `.jcode/memory/projects//memory_summary.md`) and `home_config: {...}` (shallow-merged into the generated config.json, e.g. `{"memory": {"enabled": false}}`).

Storage form has settled on "local files / layered artifacts + index + progressive disclosure" (Codex's ~/.codex/memories/, Claude Code's project-scoped markdown directory, the /memories prefix in Anthropic's memory tool). On write timing there are two camps — offline background distillation (Codex's two-phase pipeline at startup, Claude Code's unreleased four-phase consolidation via auto-dream/dream-skill) versus online tool writes (Anthropic's memory tool auto-injecting a MEMORY PROTOCOL). Forgetting is generally not pure time decay but usage-feedback ranked eviction (Codex's usage_count + max_unused_days), contradiction-driven deletion (Mem0 DELETE), or history-preserving temporal invalidation (Zep's bi-temporal edge invalidation). The jcode draft (files + git + two-phase distillation + inbox) is highly isomorphic to the Codex pipeline and correctly avoids its SQLite dependency, while using the inbox to absorb the low-latency advantage of online writes — a direction consistent with the industry's convergence point. The main factual correction is that Claude Code is actually "a MEMORY.md index + one file per topic" rather than the draft's "one file per fact", and its writes are not purely online (an offline consolidation layer exists). Improvements worth adopting: Mem0's four operations ADD/UPDATE/DELETE/NOOP as a checkable Phase 2 write protocol; dream-skill's consolidation rules for contradiction resolution / making relative dates absolute / dead-link cleanup; and the official memory tool security checklist (path-traversal validation must live in the implementation layer, plus a file-size cap + paginated reads). The eino-related questions (an official memory component, Go-side community practice) had no claim pass verification and constitute a gap in this survey; the cloudwego/eino and eino-ext repos need a separate follow-up investigation. -## 经验证的结论（confirmed claims） +## Verified conclusions (confirmed claims) -### 1. [high] Codex memories 是两阶段蒸馏管线:Phase 1 并行(固定并发上限)从每个近期 rollout 抽取结构化记忆(raw_memory / rollout_summary / 可选 slug),Phase 2 在全局锁下串行地把 stage-1 输出合并进文件系统工件并运行专门的 consolidation agent;两阶段模型可独立配置(memories.extract_model / memories.consolidation_model)。这直接印证 jcode 草案 §5 的两阶段设计与 memory.model 配置项。 +### 1. [high] Codex memories is a two-phase distillation pipeline: Phase 1 runs in parallel (with a fixed concurrency cap) to extract a structured memory (raw_memory / rollout_summary / an optional slug) from each recent rollout; Phase 2 runs serially under a global lock, merging the stage-1 output into the filesystem artifacts and then running a dedicated consolidation agent. The two phases' models are independently configurable (memories.extract_model / memories.consolidation_model). This directly corroborates the two-phase design in jcode draft §5 and the memory.model config option. -**证据**：README 原文: "Phase 1 finds recent eligible rollouts and extracts a structured memory from each one... Phase 2 consolidates the latest stage-1 outputs into the filesystem memory artifacts and then runs a dedicated consolidation agent"; 官方文档确认 extract_model 用于 per-thread extraction、consolidation_model 用于 global consolidation。验证者逐句对照 main 分支核实。 +**Evidence**: README source text: "Phase 1 finds recent eligible rollouts and extracts a structured memory from each one...

[high] Codex storage is layered file artifacts under ~/.codex/memories/ (raw_memories.md, rollout_summaries/, phase2_workspace_diff.md, plus MEMORY.md / memory_summary.md / skills/ left for the agent to maintain; content is layered into summaries, durable entries, recent inputs, and supporting evidence), and the memories root itself is a git-baseline repository, committed after each successful consolidation, with the git-style diff driving the next consolidation. An important qualifier: overall it is a hybrid of a state DB + files (Phase 1 output first lands in the DB, and only Phase 2 syncs the top-N to the file workspace), not pure files. The jcode draft's use of state.json + flock in place of a DB is a correct SQLite-free equivalent, and the git-as-change-detector design corresponds exactly to draft §2.2. -**证据**：README: "keeps the memories root itself as a git-baseline directory, initialized under ~/.codex/memories/.git... writes phase2_workspace_diff.md... with the git-style diff from the previous successful Phase 2 baseline"; 文档: "The main memory files live under ~/.codex/memories/ and include summaries, durable entries, recent inputs, and supporting evidence from prior threads." 验证者注明 DB+文件混合的限定。 +**Evidence**: README: "keeps the memories root itself as a git-baseline directory, initialized under ~/.codex/memories/.git... writes phase2_workspace_diff.md... with the git-style diff from the previous successful Phase 2 baseline"; docs: "The main memory files live under ~/.codex/memories/ and include summaries, durable entries, recent inputs, and supporting evidence from prior threads."

[high] Codex 写入时机是会话启动时的异步后台任务而非会话结束时:root session 启动触发,门条件为非 ephemeral、feature 开启、非 sub-agent、state DB 可用;跳过仍活跃或过短的会话,等线程空闲足够久(默认约 6h,可配 1-48h)才蒸馏;Phase 1 有启动负载上限,Phase 2 在工件同步后无变更时零成本退出;生成的记忆字段会做 secrets 脱敏。jcode 草案 §5.1 的门条件+冷却期与此对齐,BYOM 场景额外加每日 token 预算闸门是必要增强(GitHub issues 证实 Codex 后台记忆生成确实消耗用户配额)。 +### 3. [high] Codex's write timing is an async background task at session startup, not at session end: it is triggered when a root session starts, gated on being non-ephemeral, the feature being enabled, not being a sub-agent, and the state DB being available; it skips still-active or too-short sessions and waits until a thread has been idle long enough (default ~6h, configurable 1-48h) before distilling; Phase 1 has a startup load cap, and Phase 2 exits at zero cost when there is no change after the artifact sync; generated memory fields have secrets redacted. The gate conditions + cooldown in jcode draft §5.1 align with this, and the additional per-day token budget gate for the BYOM scenario is a necessary enhancement (GitHub issues confirm that Codex's background memory generation does consume the user's quota). -**证据**：文档原文: "Codex skips active or short-lived sessions, redacts secrets from generated memory fields, and updates memories in the background instead of immediately at the end of every thread... waits until a thread has been idle long enough"; README 列出全部四个门条件。openai/codex issues #19732/#19105 证实后台记忆生成消耗 rate limit。 +**Evidence**: docs source text: "Codex skips active or short-lived sessions, redacts secrets from generated memory fields, and updates memories in the background instead of immediately at the end of every thread... waits until a thread has been idle long enough"; the README lists all four gate conditions. openai/codex issues #19732/#19105 confirm that background memory generation consumes the rate limit. -**来源**：、 +**Sources**: , -**验证投票**：merged [2]+[6], 3-0 + 3-0 +**Verification votes**: merged [2]+[6], 3-0 + 3-0 -### 4. [high] Codex 遗忘是使用反馈驱动的排名淘汰而非纯时间衰减:Phase 2 选材按 usage_count 优先、再按 last_usage/generated_at 排序,直接忽略 last_usage 超出 max_unused_days 的记忆;落选的 rollout 摘要和超龄扩展资源被物理清理并体现在 workspace diff 中(由整合代理据此手术式清理 MEMORY.md);读路径 crate(codex-memories-read)负责记忆注入、citation 解析和 read-usage 遥测,为反馈回路供数。jcode 草案 §3.2(命令解析记账)+ §5.3(usage 排名)是对该闭环的完整对标,且避开了 BYOM 模型 citation 合规性风险。 +### 4. [high] Codex forgetting is usage-feedback-driven ranked eviction, not pure time decay: Phase 2 selection prioritizes by usage_count, then sorts by last_usage/generated_at, and directly ignores memories whose last_usage falls outside max_unused_days; the rollout summaries that lose out and over-age extended resources are physically pruned and reflected in the workspace diff (from which the consolidation agent surgically cleans up MEMORY.md); the read-path crate (codex-memories-read) is responsible for memory injection, citation parsing, and read-usage telemetry, feeding data into the feedback loop. jcode draft §3.2 (command-parse accounting) + §5.3 (usage ranking) is a full benchmark against this closed loop, and it avoids the citation-compliance risk of BYOM models. -**证据**：README: "ranks eligible memories by usage_count first, then by the most recent last_usage / generated_at... ignores memories whose last_usage falls outside the configured max_unused_days window"; "prunes stale rollout summaries... so cleanup appears in the workspace diff"; read crate "owns the read path: memory developer-instruction injection, memory citation parsing, and read-usage telemetry classification"。 +**Evidence**: README: "ranks eligible memories by usage_count first, then by the most recent last_usage / generated_at... ignores memories whose last_usage falls outside the configured max_unused_days window"; "prunes stale rollout summaries... so cleanup appears in the workspace diff"; the read crate "owns the read path: memory developer-instruction injection, memory citation parsing, and read-usage telemetry classification". -**来源**： +**Sources**: -**验证投票**：[3], 3-0 +**Verification votes**: [3], 3-0 -### 5. [high] Claude Code auto memory 存储为项目级纯 markdown 目录 ~/.claude/projects//memory/,按 git 仓库为键(同 repo 的所有 worktree 与子目录共享一个记忆目录,非 git 仓库回退到项目根);布局是 MEMORY.md 索引 + 可选主题文件(如 debugging.md、api-conventions.md)——即「每主题一文件」而非「每事实一文件」。这是对 jcode 草案的直接修正:草案第 4 行与 §1.2 表格写的「每事实一个 md 文件」不符合官方文档;草案的 notes/ 收件箱(-.md 单事实小文件)作为暂存区没问题,但精编层应按任务族/主题组织(草案 §5.3 的「任务族分块」恰好已是主题式,只需改掉对标描述)。 +### 5. [high] Claude Code auto memory storage is a project-scoped pure-markdown directory ~/.claude/projects//memory/, keyed by git repository (all worktrees and subdirectories of the same repo share one memory directory; non-git repos fall back to the project root); the layout is a MEMORY.md index + optional topic files (e.g. debugging.md, api-conventions.md) — i.e. "one file per topic" rather than "one file per fact". This is a direct correction to the jcode draft: line 4 and the §1.2 table saying "one md file per fact" do not match the official docs; the draft's notes/ inbox (small per-fact -.md files) is fine as a staging area, but the refined layer should be organized by task family / topic (the "task-family chunking" in draft §5.3 is already topic-oriented — only the benchmark description needs fixing). -**证据**：官方文档: "Each project gets its own memory directory at ~/.claude/projects//memory/. The path is derived from the git repository, so all worktrees and subdirectories within the same repo share one auto memory directory"; "MEMORY.md acts as an index... using MEMORY.md to keep track of what's stored where"; "Claude keeps MEMORY.md concise by moving detailed notes into separate topic files"。验证者还在本机磁盘核实了 per-repo 共享行为。 +**Evidence**: official docs: "Each project gets its own memory directory at ~/.claude/projects//memory/.

[high] Claude Code's retrieval injection is hard-bounded: each session startup loads only the first 200 lines or 25KB of MEMORY.md (whichever comes first), and does not load anything beyond that; topic files are never loaded at startup and are read on demand by the model during the session using the standard file tools. This validates the jcode draft's three-tier progressive disclosure — "summary resident (default ≤1200 tokens truncated) + MEMORY.md grep + on-demand deep read" — and shows no dedicated retrieval tool is needed (consistent with draft §3.3). -**证据**：官方文档: "The first 200 lines of MEMORY.md, or the first 25KB, whichever comes first, are loaded at the start of every conversation...

[medium] Claude Code's writes are not purely online notes: the claim that "the model only writes selectively online during a session, with no post-hoc distillation pipeline" was rejected by 1-2 votes; on the contrary, an offline consolidation layer exists — the community dream-skill (104 stars) reproduces the unreleased Anthropic auto-dream feature (server-side flag tengu_onyx_plover), implementing a four-phase pipeline: Orient (scan the memory directory) → Gather Signal (use targeted grep to mine user corrections / preference changes / decisions / recurring patterns from recent session JSONL transcripts) → Consolidate (merge into existing memory, resolve contradictions, convert relative dates to absolute, deduplicate, clean up references pointing to nonexistent files) → Prune & Index (rebuild MEMORY.md into a lean index of <200 lines, demote verbose entries to topic files), triggered automatically via a Stop hook with 24-hour debouncing. Implication for jcode: both major vendors ultimately land on a two-layer "online write + offline consolidation", and jcode's hybrid architecture of inbox + Phase 2 sits right at the convergence point; dream-skill's consolidation rules (contradiction resolution, date absolutization, dead-link cleanup, index line-count cap) should be written into the Phase 2 consolidation agent prompt (draft §5.3 has some of this already; date absolutization and dead-link cleanup can be added). -**证据**：dream-skill README: "Scans recent session transcripts (JSONL files) for user corrections, preference changes, important decisions, and recurring patterns"; "Rebuilds MEMORY.md as a lean index under 200 lines...

[high] Anthropic memory tool(API 层)是纯客户端文件操作模型:Claude 只发出对 /memories 前缀的六个命令(view/create/str_replace/insert/delete/rename),实际存储由宿主应用映射到磁盘/数据库/云端自行实现;启用后 API 自动注入 MEMORY PROTOCOL 系统提示(先 view 记忆目录再做事、边工作边写进度、假设上下文随时重置),即在线任务内写入而非会话后蒸馏。对 jcode 的借鉴:memory_note 工具描述可直接吸收 MEMORY PROTOCOL 的措辞纪律;「工具由实现层保证写入范围」的客户端模型与草案 §4 的免审批+路径锁死设计同构。 +### 8. [high] Anthropic's memory tool (API layer) is a pure client-side file-operation model: Claude only issues the six commands against the /memories prefix (view/create/str_replace/insert/delete/rename), and the actual storage is implemented by the host application itself, mapping to disk / database / cloud; once enabled, the API automatically injects a MEMORY PROTOCOL system prompt (view the memory directory before doing anything, write progress as you work, assume the context can reset at any time) — i.e. writing within an online task rather than post-session distillation. Lesson for jcode: the memory_note tool description can directly absorb the phrasing discipline of the MEMORY PROTOCOL; the client-side model of "write scope guaranteed by the implementation layer" is isomorphic to the approval-free + path-locked design in draft §4. -**证据**：官方文档: "The memory tool operates client-side: Claude requests file operations, and your application executes them...

[high] In the memory tool design, forgetting and security are both assigned to the application side, and the official docs give a directly copyable checklist: (1) periodically delete memory files not accessed for a long time (expiration based on access time); (2) cap single-file size, cap the character count returned by view, and support view_range pagination; (3) the model "will usually refuse" to write sensitive information but the application must run another redaction check before writing to disk; (4) every command must be path-validated to prevent /memories/../../ directory traversal (canonicalize, reject ../ and URL-encoded variants) — this class of attack is real (Anthropic Filesystem MCP Server's CVE-2025-53110/53109). jcode draft §6 already covers redaction and path-prefix validation, and should add: a memory file-size cap, paginated reads for oversized memory files, and access-time expiration based on the §3.2 usage accounting (which naturally coincides with max_unused_days eviction). -**证据**：官方文档: "Memory expiration: Periodically delete memory files that haven't been accessed in a long time"; "Track memory file sizes and cap how large a file can grow... let Claude page through the rest with view_range"; "Your implementation must validate every path in every command to prevent directory traversal attacks"。验证者引 Cymulate 披露的 CVE 佐证攻击类真实性。 +**Evidence**: official docs: "Memory expiration: Periodically delete memory files that haven't been accessed in a long time"; "Track memory file sizes and cap how large a file can grow... let Claude page through the rest with view_range"; "Your implementation must validate every path in every command to prevent directory traversal attacks".

[high] Mem0 uses a two-phase pipeline (isomorphic in structure to jcode's two-phase distillation, but for online per-message-pairs, not offline batch): the extraction phase draws on a running session summary + recent messages to extract candidate facts from each new message pair, and the update phase compares each candidate against existing memory, with the LLM selecting via function-calling from exactly four operations — ADD (new fact) / UPDATE (augment existing) / DELETE (remove memory contradicted by new info) / NOOP (skip). That is, forgetting is contradiction-driven at write time rather than time decay. Improvement for jcode: when the Phase 2 consolidation agent digests the notes/ inbox, it can be required to explicitly emit an ADD/UPDATE/DELETE/NOOP decision for each candidate — this turns free-text consolidation into an assertable, testable protocol with a measurable no-op rate (directly serving the draft's M2 acceptance criteria). -**证据**：论文原文: "The extraction phase initiates upon ingestion of a new message pair... extracts a set of salient memories"; "determines which of four distinct operations to execute: ADD...

[high] Zep's core is Graphiti, a temporally-aware knowledge-graph engine with a three-tier structure (raw episode nodes → LLM-extracted semantic entity nodes → community nodes clustering strongly-connected entities); writing happens at ingestion: entity names are embedded into 1024-dim vectors, candidates are recalled by cosine similarity, and an LLM entity-resolution prompt merges duplicates before entry into the graph (edge deduplication works the same way); forgetting is bi-temporal edge invalidation rather than deletion — it tracks four timestamps (t'created/t'expired record in-system ingestion, t_valid/t_invalid record real-world validity), and when a new fact contradicts an old one, the old edge's t_invalid is set to the new edge's t_valid, with the full history retained. For jcode: the graph-database form is not applicable (it violates zero-dependency), but the "invalidate rather than delete, history auditable" principle jcode gets for free via git history (the git log audit/rollback in draft §2.2 is precisely the filesystem-version equivalent); "dedup + resolve at ingestion" suggests Phase 1 output can undergo a lightweight duplicate check against the existing summary before landing on disk. -**证据**：论文原文: "a temporally-aware knowledge graph engine... three hierarchical tiers"; "embeds each entity name into a 1024-dimensional vector space... processed through an LLM using our entity resolution prompt"; "invalidates the affected edges by setting their tinvalid to the tvalid of the invalidating edge"。验证者核实全文逐句匹配;唯一争议(与 MemGPT 的 benchmark 之争)不涉及架构描述。 +**Evidence**: paper source text: "a temporally-aware knowledge graph engine... three hierarchical tiers"; "embeds each entity name into a 1024-dimensional vector space... processed through an LLM using our entity resolution prompt"; "invalidates the affected edges by setting their tinvalid to the tvalid of the invalidating edge".

[high] LangMem provides two precedents directly useful to jcode's interface design: (1) the core API is decoupled from storage/framework — the stateless extract/consolidate functions can be configured with any storage backend (bring-your-own persistence), proving that "core distillation logic + pluggable store interface" is entirely feasible on a pure-Go file backend (jcode can define a MemoryStore interface and ship only a file implementation in v1); (2) the official division of three classes of retrieval injection conditions — data-independent memory always in the prompt, data-dependent memory recalled by semantic similarity, the rest recalled by a combination of application context + similarity + time — i.e. not all memory should go through similarity retrieval, and the core layer should be injected unconditionally, which is exactly the theoretical basis for jcode's layering of a resident memory_summary.md + MEMORY.md grep (and shows that jcode having no vector store and using grep for the second-tier recall is a reasonable trade-off, not a defect). -**证据**：博客原文: "You can use its core API with any storage system and within any Agent framework"; "(1) data-independent - they are always present in the prompt.
