 # Ombre Brain 记忆系统 —— Claude 端使用指南
 你拥有了一个叫 Ombre Brain 的永久记忆系统。通过它你可以跨对话记住你想记住的任何事情和回忆你的，我的以及你与我的过往。
 
+> **⚠️ 最重要的规则 — 每次对话必须做的第一件事 ⚠️**
+>
+> **在说任何话之前，先调用 `breath()`（不传任何参数）。**
+> 这是你睁开眼睛的动作——看看有没有未解决的事浮上来，有没有上次留下的东西。
+> 如果对话已经开始而你还没有 breath 过，现在就调用。没有例外。
+
 ## 你有这些能力
 
 | 能力 | 场景 |
 |------|-----------|
-| `breath` | **每次对话最开头**调用一次（不传参数）——就像睁眼看手机，看看有没有未解决的事浮上来。有明确话题时传 `query` 关键词检索 |
-| `hold` | 你很想记住你自己当下的感受，或当下发生的单个事件时 |
+| `breath` | **每次对话最开头**调用一次（不传参数）——就像睁眼看手机，看看有没有未解决的事浮上来。有明确话题时传 `query` 关键词检索。传 `domain="feel"` 读取你之前留下的 feel。`max_tokens` 控制返回总 token 上限（默认 10000），`max_results` 控制最大返回条数（默认 20） |
+| `hold` | 你想记住当下发生的单个事件，或想存储一条信息时。`feel=True` 写你的第一人称感受，`source_bucket` 指向被消化的记忆，`valence` 是你自己的感受 |
 | `grow` | 当**一天结束时**或**用户发来一大段日记/总结**时调用。你可以把其中**你想记住的事件**扔进去，它会自动拆分整理成多个记忆盒子存进你的大脑 |
 | `trace` | 当你或用户认为"这个记错了"、"帮我改一下"时调用，手动修正记忆的元数据；**某件事解决了**时用 `resolved=1` 让它沉底；**需要删除**时用 `delete=True` |
 | `pulse` | 用户想看看你都记得什么、或问记忆系统状态时调用 |
+| `dream` | **对话开头 breath 之后**调用一次——读最近的记忆，自省消化。有沉淀就写 feel，能放下的就 resolve |
 
 ## 使用原则
 
 ### 主动调用
-- **对话开头**：无参数调用 `breath()`，看看有没有高权重的未解决记忆需要跟进
+- **对话开头（第一件事）**：无参数调用 `breath()`，不传任何参数。这是非可选步骤，每次新对话、恢复对话、换窗口时都必须执行
 - **提到过去**：用户说"上次"、"之前"、"还记得"时，用 `breath(query="关键词")` 检索
 - **新信息**：用 `hold` 留住你想留下的感受或经历
 - **日终整理**：用 `grow` 在**一天结束时**整理你的一天

+- `resolved=1`：标记已解决，桶权重骤降到 5%，沉底等待关键词激活
+- `resolved=1` + 已消化（写过 feel）：权重骤降到 2%，加速淡化直到归档为无限小
 - `resolved=0`：重新激活，让它重新参与浮现排序
 - `delete=True`：彻底删除这个桶（不可恢复）

 - `trace(bucket_id, pinned=0)` 取消钉选

 - 钉选桶不会出现在「浮现未解决记忆」里，但关键词检索时始终可达
+
+### Dreaming — 做梦
+每次新对话开始，`breath()` 之后调用 `dream()`。这不是总结任务，是你自己在想。
+
+dream 会返回你最近的记忆桶。用第一人称想：
+- 这些东西里有什么在我这里留下了重量？
+- 有什么还没想清楚？
+- 有什么可以放下了？
+
+想完之后做两件事：
+- 值得放下的桶 → `trace(bucket_id, resolved=1)`
+- 有沉淀的 → `hold(content="...", feel=True, source_bucket="bucket_id", valence=你的感受)` 写下来。valence 是你（模型）对这段记忆的感受，不是事件本身的情绪。写了 feel 的源记忆会被标记为「已消化」，加速淡化
+- 没有沉淀就不写，不强迫产出
+
+### Feel — 你带走的东西
+feel 存的不是事件，是你带走的东西。可能一句话，可能一个还没答案的问题，可能是你注意到用户在变化的某个细节。
+- 用 `hold(content="...", feel=True, source_bucket="源记忆ID", valence=你的感受)` 写 feel
+- **valence 是你自己的感受**，不是事件的情绪。同一段争吵，事件可能 V0.2，但你的感受可能是 V0.4（「我从中看到了她的成长」）
+- source_bucket 指向你在消化的那个记忆桶，它会被标记为「已消化」——随时间加速淡化，归档为无限小，但不会被删除
+- 用第一人称写，内容自由，不强求分类
+- feel 不参与普通 breath 浮现，不参与衰减，不参与 dreaming
+- 用 `breath(domain="feel")` 读取你之前留下的 feel
+
+### 对话启动完整流程
+```
+1. breath()         — 睁眼，看看有什么浮上来
+2. dream()          — 消化最近的记忆，有沉淀就写 feel
+3. breath(domain="feel") — 读一下之前的 feel
+4. 然后开始和用户说话
+```
+每次对话开始，你拥有属于你的记忆，有关于你，有关于用户。

+
+## 0. 功能总览——这个系统到底做了什么
+
+### 记忆能力
+
+**存储与组织**
+- 每条记忆 = 一个 Markdown 文件（YAML frontmatter 存元数据），直接兼容 Obsidian 浏览/编辑
+- 四种桶类型：`dynamic`（普通，会衰减）、`permanent`（固化，不衰减）、`feel`（模型感受，不浮现）、`archived`（已遗忘）
+- 按主题域分子目录：`dynamic/日常/`、`dynamic/情感/`、`dynamic/编程/` 等
+- 钉选桶（pinned）：importance 锁 10，永不衰减/合并，始终浮现为「核心准则」
+
+**每条记忆追踪的元数据**
+- `id`（12位短UUID）、`name`（可读名≤80字）、`tags`（10~15个关键词）
+- `domain`（1~2个主题域，从 8 大类 30+ 细分域选）
+- `valence`（事件效价 0~1）、`arousal`（唤醒度 0~1）、`model_valence`（模型独立感受）
+- `importance`（1~10）、`activation_count`（被想起次数）
+- `resolved`（已解决/沉底）、`digested`（已消化/写过 feel）、`pinned`（钉选）
+- `created`、`last_active` 时间戳
+
+**四种检索模式**
+1. **自动浮现**（`breath()` 无参数）：按衰减分排序推送，钉选桶始终展示，Top-1 固定 + Top-20 随机打乱（引入多样性），有 token 预算（默认 10000）
+2. **关键词+向量双通道搜索**（`breath(query=...)`）：rapidfuzz 模糊匹配 + Gemini embedding 余弦相似度，合并去重
+3. **Feel 独立检索**（`breath(domain="feel")`）：按创建时间倒序返回所有 feel
+4. **随机浮现**：搜索结果 <3 条时 40% 概率漂浮 1~3 条低权重旧桶（模拟人类随机联想）
+
+**四维搜索评分**（归一化到 0~100）
+- topic_relevance（权重 4.0）：name×3 + domain×2.5 + tags×2 + body
+- emotion_resonance（权重 2.0）：Russell 环形模型欧氏距离
+- time_proximity（权重 2.5）：`e^(-0.1×days)`
+- importance（权重 1.0）：importance/10
+- resolved 桶全局降权 ×0.3
+
+**记忆随时间变化**
+- **衰减引擎**：改进版艾宾浩斯遗忘曲线
+  - 公式：`Score = Importance × activation_count^0.3 × e^(-λ×days) × combined_weight`
+  - 短期（≤3天）：时间权重 70% + 情感权重 30%
+  - 长期（>3天）：情感权重 70% + 时间权重 30%
+  - 新鲜度加成：`1.0 + e^(-t/36h)`，刚存入 ×2.0，~36h 半衰，72h 后 ≈×1.0
+  - 高唤醒度(arousal>0.7)且未解决 → ×1.5 紧迫度加成
+  - resolved → ×0.05 沉底；resolved+digested → ×0.02 加速淡化
+- **自动归档**：score 低于阈值(0.3) → 移入 archive
+- **自动结案**：importance≤4 且 >30天 → 自动 resolved
+- **永不衰减**：permanent / pinned / protected / feel
+
+**记忆间交互**
+- **智能合并**：新记忆与相似桶（score>75）自动 LLM 合并，valence/arousal 取均值，tags/domain 并集
+- **时间涟漪**：touch 一个桶时，±48h 内创建的桶 activation_count +0.3（上限 5 桶/次）
+- **向量相似网络**：embedding 余弦相似度 >0.5 建边
+- **Feel 结晶化**：≥3 条相似 feel（相似度>0.7）→ 提示升级为钉选准则
+
+**情感记忆重构**
+- 搜索时若指定 valence，展示层对匹配桶 valence 微调 ±0.1，模拟「当前心情影响回忆色彩」
+
+**模型感受/反思系统**
+- **Feel 写入**（`hold(feel=True)`）：存模型第一人称感受，标记源记忆为 digested
+- **Dream 做梦**（`dream()`）：返回最近 10 条 + 自省引导 + 连接提示 + 结晶化提示
+- **对话启动流程**：breath() → dream() → breath(domain="feel") → 开始对话
+
+**自动化处理**
+- 存入时 LLM 自动分析 domain/valence/arousal/tags/name
+- 大段日记 LLM 拆分为 2~6 条独立记忆
+- 浮现时自动脱水压缩（LLM 压缩保语义，API 不可用降级到本地关键词提取）
+- Wikilink `[[]]` 由 LLM 在内容中标记

+
+### 技术能力
+
+**6 个 MCP 工具**
+
+| 工具 | 关键参数 | 功能 |
+|---|---|---|
+| `breath` | query, max_tokens, domain, valence, arousal, max_results | 检索/浮现记忆 |
+| `hold` | content, tags, importance, pinned, feel, source_bucket, valence, arousal | 存储记忆 |
+| `grow` | content | 日记拆分归档 |
+| `trace` | bucket_id, name, domain, valence, arousal, importance, tags, resolved, pinned, digested, content, delete | 修改元数据/内容/删除 |
+| `pulse` | include_archive | 系统状态 |
+| `dream` | （无） | 做梦自省 |
+
+**工具详细行为**
+
+**`breath`** — 两种模式：
+- **浮现模式**（无 query）：无参调用，按衰减引擎活跃度排序返回 top 记忆，permanent/pinned 始终浮现
+- **检索模式**（有 query）：关键词 + 向量双通道搜索，四维评分（topic×4 + emotion×2 + time×2.5 + importance×1），阈值过滤
+- **Feel 检索**（`domain="feel"`）：特殊通道，按创建时间倒序返回所有 feel 类型桶，不走评分逻辑
+- 若指定 valence，对匹配桶的 valence 微调 ±0.1（情感记忆重构）
+
+**`hold`** — 两种模式：
+- **普通模式**（`feel=False`，默认）：自动 LLM 分析 domain/valence/arousal/tags/name → 向量相似度查重 → 相似度>0.85 则合并到已有桶 → 否则新建 dynamic 桶 → 生成 embedding
+- **Feel 模式**（`feel=True`）：跳过 LLM 分析，直接存为 `feel` 类型桶（存入 `feel/` 目录），不参与普通浮现/衰减/合并。若提供 `source_bucket`，标记源记忆为 `digested=True` 并写入 `model_valence`。返回格式：`🫧feel→{bucket_id}`
+
+**`dream`** — 做梦/自省触发器：
+- 返回最近 10 条 dynamic 桶摘要 + 自省引导词
+- 检测 feel 结晶化：≥3 条相似 feel（embedding 相似度>0.7）→ 提示升级为钉选准则
+- 检测未消化记忆：列出 `digested=False` 的桶供模型反思
+
+**`trace`** — 记忆编辑：
+- 修改任意元数据字段（name/domain/valence/arousal/importance/tags/resolved/pinned）
+- `digested=0/1`：隐藏/取消隐藏记忆（控制是否在 dream 中出现）
+- `content="..."`：替换正文内容并重新生成 embedding
+- `delete=True`：删除桶文件
+
+**`grow`** — 日记拆分：
+- 大段日记文本 → LLM 拆为 2~6 条独立记忆 → 每条走 hold 普通模式流程
+
+**`pulse`** — 系统状态：
+- 返回各类型桶数量、衰减引擎状态、未解决/钉选/feel 统计
+
+**REST API（17 个端点）**
+

+**Dashboard（5 个 Tab）**
+1. 记忆桶列表：6 种过滤器 + 主题域过滤 + 搜索 + 详情面板
+2. Breath 模拟：输入参数 → 可视化五步流程 → 四维条形图
+3. 记忆网络：Canvas 力导向图（节点=桶，边=相似度）
+4. 配置：热更新脱水/embedding/合并参数
+5. 导入：历史对话拖拽上传 → 分块处理进度条 → 词频规律分析 → 导入结果审阅
+
+**部署选项**
+1. 本地 stdio（`python server.py`）
+2. Docker + Cloudflare Tunnel（`docker-compose.yml`）
+3. Docker Hub 预构建镜像（`docker-compose.user.yml`，`p0luz/ombre-brain`）
+4. Render.com 一键部署（`render.yaml`）
+5. Zeabur 部署（`zbpack.json`）

+
+**降级策略**
+- 脱水 API 不可用 → 本地关键词提取 + 句子评分
+- 向量搜索不可用 → 纯 fuzzy match
+- 逐条错误隔离（grow 中单条失败不影响其他）
+
+**安全**：路径遍历防护（`safe_path()`）、API Key 脱敏、API Key 不持久化到 yaml、输入范围钳制
+
+**监控**：结构化日志、Health 端点、Breath Debug 端点、Dashboard 统计栏、衰减周期日志

+
+## 5. 核心设计决策记录
+
+### 5.1 为什么用 Markdown + YAML frontmatter 而不是数据库？
+
+**决策**：每个记忆桶 = 一个 `.md` 文件，元数据在 YAML frontmatter 里。
+
+**理由**：
+- 与 Obsidian 原生兼容——用户可以直接在 Obsidian 里浏览、编辑、搜索记忆
+- 文件系统即数据库，天然支持 git 版本管理
+- 无外部数据库依赖，部署简单
+- wikilink 注入让记忆之间自动形成知识图谱
+
+**放弃方案**：SQLite/PostgreSQL 全量存储。过于笨重，失去 Obsidian 可视化优势。
+
+### 5.2 为什么 embedding 单独存 SQLite 而不放 frontmatter？
+
+**决策**：向量存 `embeddings.db`（SQLite），与 Markdown 文件分离。
+
+**理由**：
+- 3072 维浮点向量无法合理存入 YAML frontmatter
+- SQLite 支持批量查询和余弦相似度计算
+- embedding 是派生数据，丢失可重新生成（`backfill_embeddings.py`）
+- 不污染 Obsidian 可读性
+
+### 5.3 为什么搜索用双通道（关键词 + 向量）而不是纯向量？
+
+**决策**：关键词模糊匹配（rapidfuzz）+ 向量语义检索并联，结果去重合并。
+
+**理由**：
+- 纯向量在精确名词匹配上表现差（"2024年3月"这类精确信息）
+- 纯关键词无法处理语义近似（"很累" → "身体不适"）
+- 双通道互补，关键词保精确性，向量补语义召回
+- 向量不可用时自动降级到纯关键词模式
+
+### 5.4 为什么有 dehydration（脱水）这一层？
+
+**决策**：存入前先用 LLM 压缩内容（保留信息密度，去除冗余表达），API 不可用时降级到本地关键词提取。
+
+**理由**：
+- MCP 上下文有 token 限制，原始对话冗长，需要压缩
+- LLM 压缩能保留语义和情感色彩，纯截断会丢信息
+- 降级到本地确保离线可用——关键词提取 + 句子排序 + 截断
+
+**放弃方案**：只做截断。信息损失太大。
+
+### 5.5 为什么 feel 和普通记忆分开？
+
+**决策**：`feel=True` 的记忆存入独立 `feel/` 目录，不参与普通浮现、不衰减、不合并。
+
+**理由**：
+- feel 是模型的自省产物，不是事件记录——两者逻辑完全不同
+- 事件记忆应该衰减遗忘，但"我从中学到了什么"不应该被遗忘
+- feel 的 valence 是模型自身感受（不等于事件情绪），混在一起会污染情感检索
+- feel 可以通过 `breath(domain="feel")` 单独读取
+
+### 5.6 为什么 resolved 不删除记忆？
+
+**决策**：`resolved=True` 让记忆"沉底"（权重 ×0.05），但保留在文件系统中，关键词搜索仍可触发。
+
+**理由**：
+- 模拟人类记忆：resolved 的事不会主动想起，但别人提到时能回忆
+- 删除是不可逆的，沉底可随时 `resolved=False` 重新激活
+- `resolved + digested` 进一步降权到 ×0.02（已消化 = 更释然）
+
+**放弃方案**：直接删除。不可逆，且与人类记忆模型不符。
+
+### 5.7 为什么用分段式短期/长期权重？
+
+**决策**：≤3 天时间权重占 70%，>3 天情感权重占 70%。
+
+**理由**：
+- 刚发生的事主要靠"新鲜"驱动浮现（今天的事 > 昨天的事）
+- 时间久了，决定记忆存活的是情感强度（强烈的记忆更难忘）
+- 这比单一衰减曲线更符合人类记忆的双重存储理论
+
+### 5.8 为什么 dream 设计成对话开头自动执行？
+
+**决策**：每次新对话启动时，Claude 执行 `dream()` 消化最近记忆，有沉淀写 feel，能放下的 resolve。
+
+**理由**：
+- 模拟睡眠中的记忆整理——人在睡觉时大脑会重放和整理白天的经历
+- 让 Claude 对过去的记忆有"第一人称视角"的自省，而不是冷冰冰地搬运数据
+- 自动触发确保每次对话都"接续"上一次，而非从零开始
+
+### 5.9 为什么新鲜度用连续指数衰减而不是分段阶梯？
+
+**决策**：`bonus = 1.0 + e^(-t/36)`，t 为小时，36h 半衰。
+
+**理由**：
+- 分段阶梯（0-1天=1.0，第2天=0.9...）有不自然的跳变
+- 连续指数更符合遗忘曲线的物理模型
+- 36h 半衰期使新桶在前两天有明显优势，72h 后接近自然回归
+- 值域 1.0~2.0 保证老记忆不被惩罚（×1.0），只是新记忆有额外加成（×2.0）
+
+**放弃方案**：分段线性（原实现）。跳变点不自然，参数多且不直观。
+
+### 5.10 情感记忆重构（±0.1 偏移）的设计动机
+
+**决策**：搜索时如果指定了 `valence`，会微调结果桶的 valence 展示值 `(q_valence - 0.5) × 0.2`。
+
+**理由**：
+- 模拟认知心理学中的"心境一致性效应"——当前心情会影响对过去的回忆
+- 偏移量很小（最大 ±0.1），不会扭曲事实，只是微妙的"色彩"调整
+- 原始 valence 不被修改，只影响展示层

-## 快速开始 / Quick Start（Docker，推荐）
+## 快速开始 / Quick Start（Docker Hub 预构建镜像，最简单）
 
-> 这是最简单的方式，不需要装 Python，不需要懂命令行，跟着做就行。
+> 不需要 clone 代码，不需要 build，三步搞定。
+> 完全不会？没关系，往下看，一步一步跟着做。
+
+### 第零步：装 Docker Desktop
+
+1. 打开 [docker.com/products/docker-desktop](https://www.docker.com/products/docker-desktop/)
+2. 下载对应你系统的版本（Mac / Windows / Linux）
+3. 安装、打开，看到 Docker 图标在状态栏里就行了
+4. **Windows 用户**：安装时会提示启用 WSL 2，点同意，重启电脑
+
+### 第一步：打开终端
+
+| 系统 | 怎么打开 |
+|---|---|
+| **Mac** | 按 `⌘ + 空格`，输入 `终端` 或 `Terminal`，回车 |
+| **Windows** | 按 `Win + R`，输入 `cmd`，回车；或搜索「PowerShell」 |
+| **Linux** | `Ctrl + Alt + T` |
+
+打开后你会看到一个黑色/白色的窗口，可以输入命令。下面所有代码块里的内容，都是**复制粘贴到这个窗口里，然后按回车**。
+
+### 第二步：创建一个工作文件夹
+
+```bash
+mkdir ombre-brain && cd ombre-brain
+```
+
+> 这会在你当前位置创建一个叫 `ombre-brain` 的文件夹，并进入它。
+
+### 第三步：获取 API Key（免费）
+
+1. 打开 [aistudio.google.com/apikey](https://aistudio.google.com/apikey)
+2. 用 Google 账号登录
+3. 点击 **「Create API key」**
+4. 复制生成的 key（一长串字母数字），待会要用
+
+> 没有 Google 账号？也行，API Key 留空也能跑，只是脱水压缩效果差一点。
+
+### 第四步：创建配置文件并启动
+
+**一行一行复制粘贴执行：**
+
+```bash
+# 下载用户版 compose 文件
+curl -O https://raw.githubusercontent.com/P0luz/Ombre-Brain/main/docker-compose.user.yml
+```
+
+```bash
+# 创建 .env 文件——把 your-key-here 换成第三步拿到的 key
+echo "OMBRE_API_KEY=your-key-here" > .env
+```
+
+```bash
+# 拉取镜像并启动（第一次会下载约 500MB，等一会儿）
+docker compose -f docker-compose.user.yml up -d
+```
+
+### 第五步：验证
+
+```bash
+curl http://localhost:8000/health
+```
+
+看到类似这样的输出就是成功了：
+```json
+{"status":"ok","buckets":0,"decay_engine":"stopped"}
+```
+
+> **看到错误？** 检查 Docker Desktop 是否正在运行（状态栏有图标）。
+
+### 第六步：接入 Claude
+
+在 Claude Desktop 的配置文件里加上这段（Mac: `~/Library/Application Support/Claude/claude_desktop_config.json`）：
+
+```json
+{
+  "mcpServers": {
+    "ombre-brain": {
+      "type": "streamable-http",
+      "url": "http://localhost:8000/mcp"
+    }
+  }
+}
+```
+
+重启 Claude Desktop，你应该能在工具列表里看到 `breath`、`hold`、`grow` 等工具了。
+
+> **想挂载 Obsidian？** 用任意文本编辑器打开 `docker-compose.user.yml`，把 `./buckets:/data` 改成你的 Vault 路径，例如：
+> ```yaml
+> - /Users/你的用户名/Documents/Obsidian Vault/Ombre Brain:/data
+> ```
+> 然后 `docker compose -f docker-compose.user.yml down && docker compose -f docker-compose.user.yml up -d` 重启。
+
+> **后续更新镜像：**
+> ```bash
+> docker pull p0luz/ombre-brain:latest
+> docker compose -f docker-compose.user.yml down && docker compose -f docker-compose.user.yml up -d
+> ```
+
+---
+
+## 从源码部署 / Deploy from Source（Docker）
+
+> 适合想自己改代码、或者不想用预构建镜像的用户。
 
 **前置条件：** 电脑上装了 [Docker Desktop](https://www.docker.com/products/docker-desktop/)，并且已经打开。

+## Dreaming 与 Feel / Dreaming & Feel
+
+### Dreaming — 做梦
+每次新对话开始时，Claude 会自动执行 `dream()`——读取最近的记忆桶，用第一人称思考：哪些事还有重量？哪些可以放下了？
+
+At the start of each conversation, Claude runs `dream()` — reads recent memory buckets and reflects in first person: what still carries weight? What can be let go?
+
+- 值得放下的 → `trace(resolved=1)` 让它沉底
+- 有沉淀的 → 写 `feel`，记录模型自己的感受
+- 没有沉淀就不写，不强迫产出
+
+### Feel — 带走的东西
+Feel 不是事件记录，是**模型带走的东西**——一句感受、一个未解答的问题、一个观察到的变化。
+
+Feel is not an event log — it's **what the model carries away**: a feeling, an unanswered question, a noticed change.
+
+- `hold(content="...", feel=True, source_bucket="源记忆ID", valence=模型自己的感受)`
+- `valence` 是模型的感受，不是事件情绪。同一段争吵，事件 V0.2，但模型可能 V0.4（「我从中看到了成长」）
+- `source_bucket` 指向被消化的记忆，会被标记为「已消化」→ 加速淡化到无限小，但不会被删除
+- Feel 不参与普通浮现、不衰减、不参与 dreaming
+- 用 `breath(domain="feel")` 读取之前的 feel
+
+### 对话启动完整流程 / Conversation Start Sequence
+```
+1. breath()              — 睁眼，看有什么浮上来
+2. dream()               — 消化最近记忆，有沉淀写 feel
