Subject: [PATCH 01/18] fix: remove all process.env usage to pass OpenClaw
 >=4.2 security scan

- index.ts: remove process.env.ANTHROPIC_API_KEY, read from plugin config
- index.ts: remove process.env.OPENCLAW_PROVIDER, use hardcoded default
- bump version to 1.5.8

+## Features
 
----
+- Neo4j labels: `Task`, `Skill`, `Event`, `Community`, and `GmMessage`
+- Typed relationships: `USED_SKILL`, `SOLVED_BY`, `REQUIRES`, `PATCHES`, `CONFLICTS_WITH`
+- GDS Personalized PageRank for recall and global PageRank for maintenance
+- Neo4j vector indexes for semantic recall and duplicate detection
+- APOC-backed dynamic relationship creation and node merge
+- Community-level recall with LLM-generated summaries
+- Gateway-authenticated CRUD API at `/graph-memory-pro/api/`
 
-<p align="center">

-</p>
+## Requirements
 
-## What it does
+- OpenClaw
+- Node.js 20+
+- Java 17+ when using the bundled Linux setup
+- Neo4j 5.24.2 with APOC 5.24.2
+- GDS 2.12.0 is strongly recommended for PageRank; without it, ranking falls back to a basic order
 
-When conversations grow long, agents lose track of what happened. graph-memory solves three problems at once:
+## Linux Quick Start
 
-1. **Context explosion** — 174 messages eat 95K tokens. graph-memory compresses to ~24K by replacing raw history with structured knowledge graph nodes
-2. **Cross-session amnesia** — Yesterday's bugs, solved problems, all gone in a new session. graph-memory recalls relevant knowledge automatically via FTS5/vector search + graph traversal
-3. **Skill islands** — Self-improving agents record learnings as isolated markdown. graph-memory connects them: "installed libgl1" and "ImportError: libGL.so.1" are linked by a `SOLVED_BY` edge
-
-**It feels like talking to an agent that learns from experience. Because it does.**
-
-<p align="center">
-  <img src="docs/images/graph-ui.png" alt="graph-memory knowledge graph visualization with community detection" width="95%" />
-</p>
-
-> *58 nodes, 40 edges, 3 communities — automatically extracted from conversations. Right panel shows the knowledge graph with community clusters (GitHub ops, B站 MCP, session management). Left panel shows agent using `gm_stats` and `gm_search` tools.*
-
-## What's new in v2.0
-
-### Community-aware recall
-
-Recall now runs **two parallel paths** that merge results:
-
-- **Precise path**: vector/FTS5 search → community expansion → graph walk → PPR ranking
-- **Generalized path**: query vector vs community summary embeddings → community members → PPR ranking
-
-Community summaries are generated immediately after each community detection cycle (every 7 turns), so the generalized path is available from the first maintenance window.
-
-### Episodic context (conversation traces)
-
-The top 3 PPR-ranked nodes now pull their **original user/assistant conversation snippets** into the context. The agent sees not just structured triples, but the actual dialogue that produced them — improving accuracy when reapplying past solutions.
-
-### Universal embedding support
-
-The embedding module now uses raw `fetch` instead of the `openai` SDK, making it compatible with **any OpenAI-compatible endpoint** out of the box:
-
-- OpenAI, Azure OpenAI
-- Alibaba DashScope (`text-embedding-v4`)
-- MiniMax (`embo-01`)
-- Ollama, llama.cpp, vLLM (local models)
-- Any endpoint that implements `POST /embeddings`
-
-### Windows one-click installer
-
-v2.0 ships a **Windows installer** (`.exe`). Download from [Releases](https://github.com/adoresever/graph-memory/releases):
-
-1. Download `graph-memory-installer-win-x64.exe`
-2. Run the installer — it auto-detects your OpenClaw installation
-3. The installer configures `plugins.slots.contextEngine`, adds the plugin entry, and restarts the gateway
-
-## Real-world results
-
-<p align="center">
-  <img src="docs/images/token-comparison.png" alt="Token comparison: 7 rounds" width="85%" />
-</p>
-
-7-round conversation installing bilibili-mcp + login + query:
-
-| Round | Without graph-memory | With graph-memory |
-|-------|---------------------|-------------------|
-| R1 | 14,957 | 14,957 |
-| R4 | 81,632 | 29,175 |
-| R7 | **95,187** | **23,977** |
-
-**75% compression.** Red = linear growth without graph-memory. Blue = stabilized with graph-memory.

-</p>
-
-## How it works
-
-### The Knowledge Graph
-
-graph-memory builds a typed property graph from conversations:
-
-- **3 node types**: `TASK` (what was done), `SKILL` (how to do it), `EVENT` (what went wrong)
-- **5 edge types**: `USED_SKILL`, `SOLVED_BY`, `REQUIRES`, `PATCHES`, `CONFLICTS_WITH`
-- **Personalized PageRank**: ranks nodes by relevance to the current query, not global popularity
-- **Community detection**: automatically groups related skills (Docker cluster, Python cluster, etc.)
-- **Community summaries**: LLM-generated descriptions + embeddings for each community, enabling semantic community-level recall
-- **Episodic traces**: original conversation snippets linked to graph nodes for faithful context reconstruction
-- **Vector dedup**: merges semantically duplicate nodes via cosine similarity
-
-### Dual-path recall
-
-```
-User query
-  │
-  ├─ Precise path (entity-level)
-  │    vector/FTS5 search → seed nodes
-  │    → community peer expansion
-  │    → graph walk (N hops)
-  │    → Personalized PageRank ranking
-  │
-  ├─ Generalized path (community-level)
-  │    query embedding vs community summary embeddings
-  │    → matched community members
-  │    → graph walk (1 hop)
-  │    → Personalized PageRank ranking
-  │
-  └─ Merge & deduplicate → final context
-```
-
-Both paths run in parallel. Precise results take priority; generalized results fill gaps from uncovered knowledge domains.
-
-### Data flow
-
-```
-Message in → ingest (zero LLM)
-  ├─ All messages saved to gm_messages
-  └─ turn_index continues from DB max (survives gateway restart)
-
-assemble (zero LLM)
-  ├─ Graph nodes → XML with community grouping (systemPromptAddition)
-  ├─ PPR ranking decides injection priority
-  ├─ Episodic traces for top 3 nodes
-  ├─ Content normalization (prevents OpenClaw content.filter crash)
-  └─ Keep last turn raw messages
-
-afterTurn (async, non-blocking)
-  ├─ LLM extracts triples → gm_nodes + gm_edges
-  ├─ Every 7 turns: PageRank + community detection + community summaries
-  └─ User sends new message → extract auto-interrupted
-
-session_end
-  ├─ finalize (LLM): EVENT → SKILL promotion
-  └─ maintenance: dedup → PageRank → community detection
-
-Next session → before_prompt_build
-  ├─ Dual-path recall (precise + generalized)
-  └─ Personalized PageRank ranking → inject into context
-```
-
-### Personalized PageRank (PPR)
-
-Unlike global PageRank, PPR ranks nodes **relative to your current query**:
-
-- Ask about "Docker deployment" → Docker-related SKILLs rank highest
-- Ask about "conda environment" → conda-related SKILLs rank highest
-- Same graph, completely different rankings per query
-- Computed in real-time at recall (~5ms for thousands of nodes)
-
-## Installation
-
-### Prerequisites
-
-- [OpenClaw](https://github.com/openclaw/openclaw) (v2026.3.x+)
-- Node.js 22+
-
-### Windows users
-
-Download the installer from [Releases](https://github.com/adoresever/graph-memory/releases):
-
-```
-graph-memory-installer-win-x64.exe
-```
-
-The installer handles everything: plugin installation, context engine activation, and gateway restart. After running, skip to [Step 3: Configure LLM and Embedding](#step-3-configure-llm-and-embedding).
-
-### Step 1: Install the plugin
-
-Choose one of three methods:
-
-**Option A — From npm registry** (recommended):
+Run the setup script from this repository on Linux:
 
 ```bash
-pnpm openclaw plugins install graph-memory
+bash setup-graph-memory-pro.sh
 ```
 
-No `node-gyp`, no manual compilation. The SQLite driver (`@photostructure/sqlite`) ships prebuilt binaries — works with OpenClaw's `--ignore-scripts` install.
+The script installs a user-local Neo4j distribution in `~/.graph-memory-pro/neo4j`, configures APOC and GDS, installs or registers this local plugin, writes `~/.openclaw/openclaw.json`, and restarts the gateway when possible.
 
-**Option B — From GitHub**:
+Useful modes:
 
 ```bash
-pnpm openclaw plugins install github:adoresever/graph-memory
-```
-
-**Option C — From source** (for development or custom modifications):
-
-```bash
-git clone https://github.com/adoresever/graph-memory.git
-cd graph-memory
-npm install
-npx vitest run   # verify 80 tests pass
-pnpm openclaw plugins install .
-```
-
-### Step 2: Activate context engine
-
-This is the **critical step** most people miss. graph-memory must be registered as the context engine, otherwise OpenClaw will only use it for recall but **won't ingest messages or extract knowledge**.
-
-Edit `~/.openclaw/openclaw.json` and add `plugins.slots`:
-
-```json
-{
-  "plugins": {
-    "slots": {
-      "contextEngine": "graph-memory"
-    },
-    "entries": {
-      "graph-memory": {
-        "enabled": true
-      }
-    }
-  }
-}
+bash setup-graph-memory-pro.sh --dry-run
+bash setup-graph-memory-pro.sh --skip-neo4j --neo4j-uri bolt://localhost:7687 --neo4j-password 'your-password'
+bash setup-graph-memory-pro.sh --uninstall
 ```

-**LLM** (`config.llm`) — Required. Used for knowledge extraction and community summaries. Any OpenAI-compatible endpoint works. Use a cheap/fast model.
-
-**Embedding** (`config.embedding`) — Optional but recommended. Enables semantic vector search, community-level recall, and vector dedup. Without it, falls back to FTS5 full-text search (still works, just keyword-based).
+`embedding` is optional. When present, `dimensions` must match the Neo4j vector index dimension. For a fresh database, the plugin creates matching indexes during startup. If you change dimensions later, recreate the vector indexes or the Neo4j database.
 
-> **⚠️ Important**: `pnpm openclaw plugins install` may reset your config. Always verify `config.llm` and `config.embedding` are present after reinstalling.
+## Data Flow
 
-If `config.llm` is not set, graph-memory falls back to the `ANTHROPIC_API_KEY` environment variable + Anthropic API.
+```text
+conversation messages -> GmMessage nodes -> LLM triple extraction
+  -> Task / Skill / Event nodes + typed relationships
+  -> embeddings -> vector recall + community expansion + GDS PPR
+  -> XML context injection
 
-### Supported embedding providers
-
-| Provider | baseURL | Model | dimensions |
-|----------|---------|-------|------------|
-| OpenAI | `https://api.openai.com/v1` | `text-embedding-3-small` | 512 |
-| Alibaba DashScope | `https://dashscope.aliyuncs.com/compatible-mode/v1` | `text-embedding-v4` | 1024 |
-| MiniMax | `https://api.minimax.chat/v1` | `embo-01` | 1024 |
-| Ollama | `http://localhost:11434/v1` | `nomic-embed-text` | 768 |
-| llama.cpp | `http://127.0.0.1:8080/v1` | your model name | varies |
+session end -> dedup -> global PageRank -> communities -> summaries
+```
 
-Set `dimensions: 0` or omit it entirely if the model doesn't support the `dimensions` parameter.
+## Verify
 
-### Restart and verify
+Start OpenClaw with verbose logging:
 
 ```bash
-pnpm openclaw gateway --verbose
+openclaw gateway --verbose
 ```
 
-You should see these two lines in the startup log:
+Expected messages include:
 
+```text
+[graph-memory-pro] Neo4j schema initialized
+[graph-memory-pro] ready | neo4j=bolt://localhost:7687
 ```
-[graph-memory] ready | db=~/.openclaw/graph-memory.db | provider=... | model=...
-[graph-memory] vector search ready
-```
-
-If you see `FTS5 search mode` instead of `vector search ready`, your embedding config is missing or the API key is invalid.
 
-After a few rounds of conversation, verify:
+Inspect the graph with the bundled Cypher shell:
 
 ```bash
-# Check messages are being ingested
-sqlite3 ~/.openclaw/graph-memory.db "SELECT COUNT(*) FROM gm_messages;"
-
-# Check knowledge triples are being extracted
-sqlite3 ~/.openclaw/graph-memory.db "SELECT type, name, description FROM gm_nodes LIMIT 10;"
-
-# Check communities are detected
-sqlite3 ~/.openclaw/graph-memory.db "SELECT id, summary FROM gm_communities;"
-
-# In gateway logs, look for:
-# [graph-memory] extracted N nodes, M edges
-# [graph-memory] recalled N nodes, M edges
+~/.graph-memory-pro/neo4j/bin/cypher-shell -u neo4j -p 'your-password' \
+  "MATCH (n:Task|Skill|Event) RETURN n.type, n.name, n.pagerank ORDER BY n.pagerank DESC LIMIT 10"
 ```
 
-### Troubleshooting
-
-| Symptom | Cause | Fix |
-|---------|-------|-----|
-| `recall` works but `gm_messages` is empty | `plugins.slots.contextEngine` not set | Add `"contextEngine": "graph-memory"` to `plugins.slots` |
-| `FTS5 search mode` instead of `vector search ready` | Embedding not configured or API key invalid | Check `config.embedding` credentials |
-| `No LLM available` error | LLM config missing after plugin reinstall | Re-add `config.llm` to `plugins.entries.graph-memory` |
-| No `extracted` log after `afterTurn` | Gateway restart caused turn_index overlap | Update to v2.0 (fixes msgSeq persistence) |
-| `content.filter is not a function` | OpenClaw expects array content | Update to v2.0 (adds content normalization) |
-| Nodes are empty after many messages | `compactTurnCount` not reached | Default is 7 messages. Keep chatting or set a lower value |

+- OpenClaw
+- Node.js 20+

-大道至简——其实都是**上下文工程**。但现在有三个致命问题：
+## Linux 一键安装
 
-🔴 **上下文爆炸** — Agent 执行任务反复试错，pip 日志、git 输出、报错堆栈疯狂堆积。174 条消息吃掉 95K token，噪音远大于信号，且无法祛除。
-
-🔴 **跨对话失忆** — 昨天踩过的坑、解过的 bug，新对话全部归零。MEMORY.md 全量加载？单次召回成本 49 万 token。不加载？同样的错误来一遍。
-
-🔴 **技能孤岛** — self-improving-agent 记录的学习条目是孤立的 markdown 列表，没有因果关系、没有依赖链、没有知识体系。"装了 libgl1" 和 "ImportError: libGL.so.1" 之间毫无关联。
-
-**graph-memory 用一个方案同时解决这三个问题。**

-> *58 个节点、40 条边、3 个社区——全部从对话中自动提取。右侧面板展示知识图谱的社区聚类（GitHub 操作、B站 MCP、会话管理）。左侧面板展示 Agent 使用 `gm_stats` 和 `gm_search` 工具查询图谱。*
-
-## v2.0 新特性
-
-### 社区感知召回（双路径并行）
-
-召回现在有**两条并行路径**，结果合并去重：
-
-- **精确路径**：向量/FTS5 搜索 → 社区扩展 → 图遍历 → 个性化 PageRank 排序
-- **泛化路径**：查询向量 vs 社区摘要 embedding → 匹配社区成员 → 个性化 PageRank 排序
-
-社区摘要在每次社区检测（每 7 轮）后**立即生成**，泛化路径从第一个维护窗口开始就可用。
-
-### 溯源片段（Episodic Context）
-
-PPR 排名前 3 的节点会拉取**原始 user/assistant 对话片段**注入上下文。Agent 不仅看到结构化的三元组，还能看到产生这些知识的实际对话——提高复用过去方案时的准确性。
-
-### 通用 Embedding 兼容
-
-Embedding 模块改用原生 `fetch` 替代 `openai` SDK，开箱即用兼容**所有 OpenAI 兼容端点**：
-
-- OpenAI、Azure OpenAI
-- 阿里云 DashScope（`text-embedding-v4`）
-- MiniMax（`embo-01`）
-- Ollama、llama.cpp、vLLM（本地模型）
-- 任何实现了 `POST /embeddings` 的端点
-
-### Windows 一键安装包
-
-v2.0 提供 **Windows 安装包**（`.exe`）。从 [Releases](https://github.com/adoresever/graph-memory/releases) 页面下载：
-
-1. 下载 `graph-memory-installer-win-x64.exe`
-2. 运行安装包——自动检测 OpenClaw 安装路径
-3. 安装包自动配置 `plugins.slots.contextEngine`、添加插件条目、重启 gateway

-## 工作原理
-
-### 知识图谱
-
-graph-memory 从对话中构建类型化属性图：
-
-- **3 种节点**: `TASK`（做了什么）、`SKILL`（怎么做的）、`EVENT`（出了什么问题）
-- **5 种边**: `USED_SKILL`、`SOLVED_BY`、`REQUIRES`、`PATCHES`、`CONFLICTS_WITH`
-- **个性化 PageRank**: 根据当前查询动态排序，不是全局固定排名
-- **社区检测**: 自动将相关技能分组（Docker 集群、Python 集群等）
-- **社区摘要**: LLM 生成每个社区的描述 + embedding，实现语义级社区召回
-- **溯源片段**: 链接到图谱节点的原始对话片段，忠实还原上下文
-- **向量去重**: 通过余弦相似度合并语义重复的节点

-### 个性化 PageRank (PPR)
-
-区别于全局 PageRank，PPR **根据你当前的问题动态排序**：

-- 问 "conda 环境" → conda 相关 SKILL 分数最高
-- 同一个图谱，完全不同的排名
-- 召回时实时计算（几千节点 < 5ms）

-## 安装
-
-### 前置条件
-
-- [OpenClaw](https://github.com/openclaw/openclaw)（v2026.3.x+）
-- Node.js 22+
-
-### Windows 用户
-
-从 [Releases](https://github.com/adoresever/graph-memory/releases) 下载安装包：
-
-```
-graph-memory-installer-win-x64.exe
-```
-
-安装包自动完成：插件安装、上下文引擎激活、gateway 重启。运行后直接跳到[第三步：配置 LLM 和 Embedding](#第三步配置-llm-和-embedding)。
-
-### 第一步：安装插件
-
-三种方式任选：
-
-**方式 A — 从 npm 仓库安装**（推荐）：
+在仓库根目录运行：
 
 ```bash
-pnpm openclaw plugins install graph-memory
+bash setup-graph-memory-pro.sh
 ```
 
-不需要 `node-gyp`，不需要手动编译。SQLite 驱动（`@photostructure/sqlite`）将预编译二进制打包在 npm tarball 内。
-
-**方式 B — 从 GitHub 安装**：
-
-```bash
-pnpm openclaw plugins install github:adoresever/graph-memory
-```
+脚本会在 `~/.graph-memory-pro/neo4j` 安装用户级 Neo4j，配置 APOC/GDS，安装或注册当前本地插件，写入 `~/.openclaw/openclaw.json`，并在可用时重启 gateway。
 
-**方式 C — 从源码安装**（开发或自定义修改时使用）：
+常用参数：
 
 ```bash
-git clone https://github.com/adoresever/graph-memory.git
-cd graph-memory
-npm install
-npx vitest run   # 验证 80 个测试通过
-pnpm openclaw plugins install .
+bash setup-graph-memory-pro.sh --dry-run
+bash setup-graph-memory-pro.sh --skip-neo4j --neo4j-uri bolt://localhost:7687 --neo4j-password '你的密码'
+bash setup-graph-memory-pro.sh --uninstall
 ```
 
-### 第二步：激活上下文引擎（关键！）
+安装器默认只监听 `127.0.0.1`，Bolt 端口为 `7687`。
 
-这是**最容易遗漏的一步**。graph-memory 必须被注册为上下文引擎，否则 OpenClaw 只会用它做召回，**不会触发消息入库和知识提取**。
+## 手动配置
 
-编辑 `~/.openclaw/openclaw.json`，在 `plugins` 中添加 `slots`：
+安装插件后，在 `~/.openclaw/openclaw.json` 中配置：
 
 ```json
 {
   "plugins": {
     "slots": {
-      "contextEngine": "graph-memory"
+      "contextEngine": "graph-memory-pro"
     },
     "entries": {
-      "graph-memory": {
-        "enabled": true
-      }
-    }
-  }
-}
-```
-
-如果没有 `plugins.slots.contextEngine`，插件虽然注册成功，但 `ingest` / `assemble` / `compact` 管线不会启动——你会在日志里看到 `recall`，但数据库里没有任何数据。
-
-### 第三步：配置 LLM 和 Embedding
-
-在 `plugins.entries.graph-memory.config` 中添加 API 密钥：
-
-```json

 ```bash
-pnpm openclaw gateway --verbose
+openclaw gateway --verbose
 ```
 
-启动日志中应该看到这两行：
+启动日志应包含：
 
+```text
+[graph-memory-pro] Neo4j schema initialized
+[graph-memory-pro] ready | neo4j=bolt://localhost:7687
 ```
-[graph-memory] ready | db=~/.openclaw/graph-memory.db | provider=... | model=...
-[graph-memory] vector search ready
-```
-
-如果看到 `FTS5 search mode` 而不是 `vector search ready`，说明 embedding 配置缺失或 API Key 无效。
 
-对话几轮后验证：
+使用安装器自带的 Cypher Shell 查看图谱：
 
 ```bash
-# 检查消息是否入库
-sqlite3 ~/.openclaw/graph-memory.db "SELECT COUNT(*) FROM gm_messages;"
-
-# 检查知识三元组是否提取成功
-sqlite3 ~/.openclaw/graph-memory.db "SELECT type, name, description FROM gm_nodes LIMIT 10;"
-
-# 检查社区是否被检测和描述
-sqlite3 ~/.openclaw/graph-memory.db "SELECT id, summary FROM gm_communities;"
-
-# 在 gateway 日志中确认：
-# [graph-memory] extracted N nodes, M edges
-# [graph-memory] recalled N nodes, M edges
+~/.graph-memory-pro/neo4j/bin/cypher-shell -u neo4j -p '你的密码' \
+  "MATCH (n:Task|Skill|Event) RETURN n.type, n.name, n.pagerank ORDER BY n.pagerank DESC LIMIT 10"
 ```
 
-### 常见问题
-
-| 现象 | 原因 | 解决 |
-|------|------|------|
-| `recall` 正常但 `gm_messages` 为空 | 没设置 `plugins.slots.contextEngine` | 在 `plugins.slots` 中添加 `"contextEngine": "graph-memory"` |
-| 显示 `FTS5 search mode` | Embedding 未配置或 API Key 无效 | 检查 `config.embedding` 的密钥和地址 |
-| `No LLM available` 错误 | 重装插件后 LLM 配置丢失 | 重新添加 `config.llm` 到 `plugins.entries.graph-memory` |
-| `afterTurn` 后没有 `extracted` 日志 | 重启导致 turn_index 重叠 | 升级到 v2.0（修复了 msgSeq 持久化） |
-| `content.filter is not a function` | OpenClaw 要求 content 为数组 | 升级到 v2.0（添加了 content 规范化） |
-| 对话很多轮但节点为空 | 消息数未达到提取阈值 | 默认需要积累消息。继续对话或调低 `compactTurnCount` |
-
 ## Agent 工具
 
-| 工具 | 用途 |
-|------|------|
-| `gm_search` | 搜索图谱中的相关经验、技能和解决方案 |
-| `gm_record` | 手动记录经验到图谱 |
+| 工具 | 说明 |
+| --- | --- |
+| `gm_search` | 按查询召回图谱知识 |
+| `gm_record` | 手动记录知识节点 |
 | `gm_update` | 按精确节点名称更新已有节点的描述和/或内容（不存在则报错） |
-| `gm_stats` | 查看图谱统计：节点数、边数、社区数、PageRank Top 节点 |
-| `gm_maintain` | 手动触发图维护：去重 → PageRank → 社区检测 + 摘要生成 |
-
-## 配置参数
-
-所有参数都有默认值，只需设置想要覆盖的。
-
-| 参数 | 默认值 | 说明 |
-|------|--------|------|
-| `dbPath` | `~/.openclaw/graph-memory.db` | 数据库路径 |
-| `compactTurnCount` | `7` | 维护周期（每隔多少轮触发 PageRank + 社区检测 + 摘要） |
-| `recallMaxNodes` | `6` | 每次召回最多注入的节点数 |
-| `recallMaxDepth` | `2` | 图遍历跳数 |
-| `dedupThreshold` | `0.90` | 向量去重的余弦相似度阈值 |
-| `pagerankDamping` | `0.85` | PPR 阻尼系数 |
-| `pagerankIterations` | `20` | PPR 迭代次数 |
-
-## 数据库
-
-SQLite 通过 `@photostructure/sqlite`（预编译二进制，零编译）。默认路径：`~/.openclaw/graph-memory.db`。
-
-| 表 | 用途 |
-|----|------|
-| `gm_nodes` | 知识节点（含 pagerank + community_id） |
-| `gm_edges` | 类型化关系 |
-| `gm_nodes_fts` | FTS5 全文索引 |
-| `gm_messages` | 原始对话消息 |
-| `gm_signals` | 检测到的信号 |
-| `gm_vectors` | Embedding 向量（可选） |
-| `gm_communities` | 社区摘要 + embedding |
-
-## 与 lossless-claw 的对比
-
-| | lossless-claw | graph-memory |
-|--|---|---|
-| **方法** | 摘要 DAG | 知识图谱（三元组） |
-| **召回** | FTS grep + 子代理展开 | 双路径：实体 PPR + 社区向量匹配 |
-| **跨会话** | 仅当前对话 | 自动跨会话召回 |
-| **压缩** | 摘要（有损文本） | 结构化三元组（无损语义） |
-| **图算法** | 无 | PageRank、社区检测、向量去重 |
-| **上下文溯源** | 无 | 溯源片段（原始对话片段） |
+| `gm_stats` | 查看节点、关系、社区和 PageRank 统计 |
+| `gm_maintain` | 执行去重、PageRank 和社区维护 |

+#

+#  复刻 Windows 版 OpenClaw-Graph-2.0.0-win-x64.exe 的安装效果：
+#    - 便携式 Neo4j 5.24.2（解压到 ~/.graph-memory-pro/neo4j，免 sudo）
+#    - APOC 5.24.2 + GDS 2.12.0 插件
+#    - 安装 graph-memory-pro 插件并注册为 contextEngine
+#    - 写入 ~/.openclaw/openclaw.json（备份 + jq 安全合并）
+#
+#  用法 / Usage：
+#    bash setup-graph-memory-pro.sh                       # 全新安装（交互式填 API Key）
+#    bash setup-graph-memory-pro.sh --dry-run             # 只展示，不执行
+#    bash setup-graph-memory-pro.sh --uninstall           # 还原配置 + 停止 Neo4j
+#    bash setup-graph-memory-pro.sh --skip-neo4j          # 复用已存在的 Neo4j（只装插件+写配置）
+#    bash setup-graph-memory-pro.sh --skip-gds            # 不装 GDS（PageRank 会降级为均匀分）

+#    bash setup-graph-memory-pro.sh --no-restart          # 装完不重启 gateway
+#
+#  安全机制 / Safety：
+#    - 改 openclaw.json 前自动备份
+#    - 用 jq --arg 注入 API Key / 密码，杜绝命令注入

- *
- * 原理：每个节点初始自成一个社区，迭代中每个节点采纳邻居中最频繁的社区标签。

- * 为什么选 Label Propagation 而不是 Louvain：
- *   - 实现简单（50 行核心逻辑）
- *   - 不需要外部库
- *   - 对小图（< 10000 节点）效果够好
- *   - O(iterations * edges)，几千节点 < 5ms
- *
- * 用途：
- *   - 发现知识域（Docker 相关技能自动聚成一组）
- *   - recall 时可以拉整个社区的节点
- *   - assemble 时同社区节点放一起，上下文更连贯
- *   - kg_stats 展示社区分布

Subject: [PATCH 06/18] Bug fixes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

#1	`extractTurnKnowledge` now calls `markExtracted` on empty extraction → no more redundant reprocessing by later compact
#2	Added `isTurnExtracted()` guard at top of `extractTurnKnowledge` → if compact already marked the turn, the async per-turn extraction skips the redundant LLM call
#3	Restored normalizeMessageContent() on both assemble() return paths — wraps string/null content into [{type:"text"}], patches malformed blocks
#4	Restored prompt param on `assemble()` + fresh `recaller.recall(cleanPrompt(prompt))` with cache fallback
#5	Restored `sliceLastTurn()` — last turn verbatim, prev turns text-only (strips tool_use/tool_result), truncates >6000-char tool_results

Also removed dead code and redundant calls

+# graph-memory v1.x (SQLite) → graph-memory-pro v2.0 (Neo4j) 迁移指南
+
+将旧版 graph-memory（SQLite + FTS5）的知识图谱迁移到 graph-memory-pro v2.0（Neo4j 5 + APOC + GDS）。
+
+## 迁移内容
+
+| SQLite 表 | → Neo4j | 说明 |
+|-----------|---------|------|
+| `gm_nodes` | `(:MemoryNode:Task\|Skill\|Event)` | 知识节点（TASK/SKILL/EVENT），含 pagerank、communityId、sourceSessions |
+| `gm_edges` | 类型化关系（APOC） | USED_SKILL / SOLVED_BY / REQUIRES / PATCHES / CONFLICTS_WITH |
+| `gm_communities` | `(:Community)` | 社区摘要 + embedding |
+| `gm_vectors` | `n.embedding` 属性 | Float32 BLOB → float[]，接入 `gm_node_embedding` 向量索引 |
+| `gm_messages` | `(:GmMessage)` | **默认跳过**（25k 条原始对话，知识已提取）；可选 `--messages` 迁移 |
+
+FTS5 表、`gm_signals`（空）、`_migrations` 不迁移。
+
+## 前置条件
+
+- **Java 17+**（Neo4j 必需，唯一需要 sudo 的步骤）：
+  ```bash
+  sudo apt update && sudo apt install -y openjdk-17-jre-headless
+  ```
+- v2.0 源码（本仓库）
+- WSL Ubuntu 内能访问旧 DB：`~/.openclaw/graph-memory.db`
+
+---
+
+## 快速路径（一键）
+
+```bash
+cd /mnt/d/TEMP/graph-memory   # 或 v2.0 源码所在路径
+bash migrate/install-wsl.sh
+```
+
+runbook 自动完成：备份 → 安装 Neo4j（tmux console 模式）→ 注册插件 → 复制配置 → 禁用旧插件 → 迁移。跑完只需重启 gateway。
+
+环境变量：
+- `NEO4J_PASS=xxx` — Neo4j 密码（默认 `graphmemory`）
+- `SKIP_MIGRATE=1` — 只装不迁移
+
+---
+
+## 手动步骤（逐项）
+
+### 1. 备份 SQLite（在线一致性快照，WAL 合并）
+
+```bash
+python3 migrate/backup.py
+# → ~/graph-memory.db.bak-YYYYMMDD-HHMMSS（含全部表校验）
+```
+
+### 2. 安装 Neo4j + 注册插件
+
+用官方 setup 脚本（非交互）。Neo4j 制品可预先下载放到 `~/.graph-memory-pro/staging/` 绕过代理（见下方排障）：
+
+```bash
+bash setup-graph-memory-pro.sh --non-interactive --neo4j-password graphmemory --no-restart
+```
+
+**关键**：WSL 里 `neo4j start` 的 daemon 会在会话退出时被立即 shutdown。必须用 **tmux console 模式**保活：
+
+```bash
+tmux new-session -d -s neo4j \
+  '~/.graph-memory-pro/neo4j/bin/neo4j console > /tmp/neo4j.log 2>&1'
+# 等 Bolt 就绪
+~/.graph-memory-pro/neo4j/bin/cypher-shell -u neo4j -p graphmemory "RETURN 1"
+```
+
+### 3. 配置 openclaw.json
+
+复制旧插件的 llm/embedding 配置到新插件 + 禁用旧插件：
+
+```bash
+python3 migrate/patch_config.py                    # 复制 llm/embedding
+# 禁用旧插件（手动或一行 jq）
+python3 -c "import json,os; p=os.path.expanduser('~/.openclaw/openclaw.json'); c=json.load(open(p)); c['plugins']['entries']['graph-memory']['enabled']=False; json.dump(c,open(p,'w'),indent=2,ensure_ascii=False)"
+```
+
+确认 `contextEngine` slot 指向 `graph-memory-pro`，`openclaw.plugin.json` 声明了 `contracts.tools`（否则新版 OpenClaw 拒绝注册工具）。
+
+### 4. 迁移
+
+```bash
+cd ~/graph-memory-pro
+# uv 避开 PEP 668 externally-managed-environment
+curl -LsSf https://astral.sh/uv/install.sh | sh   # 首次
+~/.local/bin/uv venv && ~/.local/bin/uv pip install neo4j
+.venv/bin/python migrate/migrate.py ~/graph-memory.db.bak-YYYYMMDD-HHMMSS \
+  bolt://localhost:7687 neo4j graphmemory --reset
+```
+
+`--reset` 清空 Neo4j 旧数据后干净导入（首次迁移用）。重跑迁移**务必带 `--reset`**（边用 APOC create，不带会叠加）。
+
+### 5. 重启 gateway
+
+```bash
+~/.npm-global/bin/openclaw gateway restart
+~/.npm-global/bin/openclaw gateway --verbose 2>&1 | grep graph-memory-pro
+# 应见 [graph-memory-pro] ready | neo4j=bolt://localhost:7687
+```
+
+---
+
+## 可选：提取未提取消息
+
+旧 DB 可能有大量 `extracted=0` 的消息（知识尚未提取成节点）。可选地先用旧版提取器补提取，再迁移：
+
+```bash
+cd ~/.openclaw/extensions/graph-memory   # 旧插件目录（有 node_modules）
+cp /mnt/d/TEMP/graph-memory/migrate/extract_unextracted.ts .
+npx tsx extract_unextracted.ts
+```
+
+脚本用 deepseek 并发提取（BATCH=6 消息/call，20 路并发），结果写回 SQLite 备份，之后正常迁移即可带上新节点。
+
+- 自动跳过退化的 `memory-reflection-cli*` 会话（"continue" 死循环噪声）
+- 幂等：每批 `markExtracted`，崩溃可重跑续
+- 提取完重跑第 4 步迁移（带 `--reset`）
+
+---
+
+## 排障
+
+### `下载失败: dist.neo4j.org/...`
+
+WSL 走代理时大文件下载中断。解法：Windows 浏览器下载制品，放到 `migrate/staging/`，runbook 的 `dl()` 会优先用本地暂存：
+
+```
+migrate/staging/neo4j.tar.gz                         (128MB, neo4j-community-5.24.2-unix.tar.gz)
+migrate/staging/apoc-5.24.2-core.jar
+migrate/staging/neo4j-graph-data-science-2.12.0.jar  (可选；GitHub 下不到就 --skip-gds)
+```
+
+### `Neo4j Server shutdown initiated by request`（启动即停）
+
+WSL 会话退出杀 daemon。解法：用 tmux console 模式（见第 2 步），不要用 `neo4j start`。WSL 重启后需重开 tmux 会话。
+
+### `externally-managed-environment` (PEP 668)
+
+系统 Python 禁止 pip 装包。解法：用 `uv`（`curl -LsSf https://astral.sh/uv/install.sh | sh`）建 venv，不用 pip。
+
+### `plugin must declare contracts.tools before registering agent tools`
+
+新版 OpenClaw 要求 `openclaw.plugin.json` 声明 `contracts.tools`（工具名字符串数组，精确匹配）。已在 v2.0 源码修好；若自行改了工具名记得同步更新清单。
+
+### 边数量翻倍（236 而非 118）
+
+迁移不带 `--reset` 重跑导致（边用 APOC create 叠加）。解法：带 `--reset` 重跑。
+
+---
+

+
+## migrate.py 用法
+
+```
+python3 migrate.py <snapshot.db> <neo4j-uri> <user> <password> [--messages] [--reset]
+```
+
+| 参数 | 作用 |
+|------|------|

+| `--messages` | 同时迁移 gm_messages（25k 条 GmMessage，默认跳过） |
+
+幂等性：节点/社区用 MERGE（可重复）；**边用 APOC create（不幂等，重跑带 `--reset`）**。

# graph-memory-pro 发布线说明

## 发布线划分

| 发布线 | 分支 | 存储 | 状态 | 目标用户 |
| --- | --- | --- | --- | --- |
| **v1.x mainline** | `main` / `dev` | SQLite + FTS5 | 维护中 | Windows 桌面 / 无 Neo4j 环境 |
| **v2.0 desktop-2.0** | `2.0` | Neo4j 5 + APOC + GDS | 新增 | Linux 工作站 / 服务器 |

v2.0 是 Windows v2.0.0 桌面包的 Linux 对应版本。**不应直接合并到 `dev`** —— `dev` 保留 v1.x SQLite 主线，v2.0 作为并行发布线演进。

合并后建议在仓库维护层面：
- `dev` 继续作为 v1.x 主线，保留所有 SQLite 回归测试
- 从 v2.0 起，新分支命名遵循 `2.x`、`2.x-next` 等
- 跨发布线的 cherry-pick 需显式标注（PR 标题加 `[2.0]` / `[1.x]`）

## 版本号约定

`package.json` 的 `version` 字段：

```
v1.x 主线:    1.x.y
v2.0 发布线:  2.0.z           # 当前 2.0.0
未来 v2.x:    2.x.y
```

OpenClaw 插件 ID：
- v1.x: `graph-memory`
- v2.0: `graph-memory-pro`

二者可在同一 OpenClaw 实例共存（不同的 `plugins.entries` key），通过 `slots.contextEngine` 切换激活。

## 测试资产边界

| 测试套件 | v1.x 主线 | v2.0 发布线 |
| --- | --- | --- |
| SQLite 回归（store/migration/graph/recall/embed/llm-guard/assemble） | ✅ 必须保留 | 不适用（已迁移到 Neo4j） |
| 纯逻辑单元（normalize-name / clean-prompt / slice-last-turn 等） | ✅ 共享 | ✅ 共享 |
| Neo4j 集成（store/graph/assemble/recall） | 不适用 | ✅ 新增，CI 跑 |

**v2.0 删除 SQLite 测试的合理性**：存储层从 SQLite 完全迁移到 Neo4j（`AGENTS.md` 反模式清单禁止重新引入 SQLite）。原测试已由等价的 Neo4j 集成测试替换（见 `test/integration.*.test.ts`）。

**v2.0 不应删除 v1.x 的 SQLite 测试文件**：本发布线的 PR 不应触碰 `dev` 分支的 SQLite 测试。如果 v2.0 与 v1.x 在某点合并，v1.x 的 SQLite 测试应原样保留。

## CI 集成

`.github/workflows/ci.yml` 定义 4 个 job：

1. **typecheck** — `tsc --noEmit`
2. **unit-tests** — 不需 Neo4j，所有 PR 强制跑
3. **integration-tests** — Docker Neo4j 5.24.2 + APOC + GDS service container，跑 `NEO4J_INTEGRATION=1` 启用的集成测试
4. **shellcheck** — `bash -n` 语法检查 setup 脚本

集成测试 job 在 PR 改动 `src/store/`、`src/graph/`、`test/integration.*.test.ts` 时必须通过，否则阻塞合并。

## Neo4j 自启动方案（无 sudo）

`setup-graph-memory-pro.sh` 内嵌三级降级的无 sudo 自启动配置（Step 3.5）：

1. **systemd --user unit**（首选）— `~/.config/systemd/user/graph-memory-pro-neo4j.service`
   - 提供 `systemctl --user {start|stop|status}` 管理接口
   - 尝试 `loginctl enable-linger`（无需 sudo 的 polkit 配置下成功；否则仅登录后启动）

2. **cron @reboot**（兜底）— 用户级 crontab
   - 系统启动时 cron 守护进程自动拉起
   - 用 marker `# gmp-neo4j-autostart` 标记，幂等去重
   - 不依赖 linger，最兼容

3. **shell rc hook**（最低保障）— `~/.bashrc` / `~/.zshrc`
   - 仅在 systemd 与 cron 均不可用时降级
   - 用 `pgrep` 幂等，避免重复启动

`--skip-autostart` 跳过此 step。`--uninstall` 自动清理所有上述条目。

### 唯一需要 sudo 的步骤

- 安装 Java 17（Neo4j 运行依赖）—— 文档提供无 sudo 替代：`sdkman!`
- 安装 jq（配置写入）—— 文档提供无 sudo 替代：静态二进制到 `~/.local/bin`
- `loginctl enable-linger`（可选，让 systemd --user 开机即起）—— 不做也能用（cron 兜底）

`--assume-deps` 跳过所有依赖检查，适合预配置环境。

## WSL 使用边界

| 场景 | WSL 必需 | 说明 |
| --- | --- | --- |
| 纯 Linux 全新安装 | ❌ | `bash setup-graph-memory-pro.sh` 即可 |
| Windows → Linux 迁移 | ✅ | 用 `migrate/install-wsl.sh` 一键迁移（访问 Windows 侧的旧 SQLite） |
| Linux 上的 Windows v2.0 用户 | ❌ | 直接用 `setup-graph-memory-pro.sh`，无需 WSL |

`migrate/install-wsl.sh` 与 `migrate/Migrate.md` 仅用于 Windows → Linux 的 v1.x → v2.0 数据迁移路径，**不是常规安装流程**。

## 回滚

`migrate/rollback.py` 提供 v2.0 → v1.x 的回滚：
- 还原 `openclaw.json`（从 `.backup.*`）
- 禁用 `graph-memory-pro`，启用 `graph-memory`
- 校验旧 SQLite DB 可读

Neo4j 数据**不删除**（保留以备再次迁移）。如需彻底清理见 rollback 输出说明。

+
+The installer configures Neo4j to start at boot with a 3-tier no-sudo fallback:
+
+1. **systemd --user unit** (`~/.config/systemd/user/graph-memory-pro-neo4j.service`) — preferred, adds `systemctl --user` management. Best-effort `loginctl enable-linger` for boot-time start.
+2. **cron `@reboot`** — always configured as a backup so Neo4j starts even when linger is unavailable.
+3. **shell rc hook** (`~/.bashrc` / `~/.zshrc` idempotent `pgrep` guard) — last resort when systemd and cron are both unavailable.
+
+`--uninstall` cleans up all three. Only Java and jq system installs may need `sudo` (the script suggests `sdkman!` and a static `jq` binary as no-sudo alternatives).
