feat(secrets-mcp): 增强 MCP 请求日志与 encryption_key 参数支持

logging.rs:
- 每条 MCP POST 日志新增 auth_key（Bearer token 前12字符掩码）、
  enc_key（X-Encryption-Key 前4后4字符指纹，如 146b…5516(64) 或 absent）、
  user_id、tool_args（白名单非敏感参数摘要）字段
- 新增辅助函数 mask_bearer / mask_enc_key / extract_tool_args / summarize_value

tools.rs:
- extract_enc_key 成功路径增加 debug 级指纹日志（raw_len/trimmed_len/prefix/suffix）
- 新增 extract_enc_key_or_arg / require_user_and_key_or_arg：优先使用参数传入的密钥，
  fallback 到 X-Encryption-Key 头，绕过 Cursor Chat MCP 头透传异常
- GetSecretInput / AddInput / UpdateInput / ExportInput / EnvMapInput 各增加可选
  encryption_key 字段，对应工具实现改用 require_user_and_key_or_arg

-## 提交 / 发版硬规则（优先于下文其他说明）
+本仓库为 **MCP SaaS**：`secrets-core`（业务与持久化）+ `secrets-mcp`（Streamable HTTP MCP、Web、OAuth、API Key）。对外入口见 `crates/secrets-mcp`。
 
-1. 涉及 `src/**`、`Cargo.toml`、`Cargo.lock`、CLI 行为变更的提交，默认视为**需要发版**，除非用户明确说明“本次不发版”。
-2. 发版前必须先检查 `Cargo.toml` 中的 `version`，再检查是否已存在对应 tag：`git tag -l 'secrets-*'`。
-3. 若当前版本对应 tag 已存在，必须先 bump `Cargo.toml` 的 `version`，再执行 `cargo build` 同步 `Cargo.lock`，然后才能提交。
-4. 提交前优先运行 `./scripts/release-check.sh`；该脚本会检查重复版本并执行 `cargo fmt -- --check && cargo clippy --locked -- -D warnings && cargo test --locked`。
+## 版本控制
 
-跨设备密钥与配置管理 CLI 工具，将 refining / ricnsmart 两个项目的服务器信息、服务凭据存储到 PostgreSQL 18，供 AI 工具读取上下文。敏感数据（encrypted 字段）使用 AES-256-GCM 加密，主密钥由 Argon2id 从主密码派生并存入平台安全存储（macOS Keychain / Windows Credential Manager / Linux keyutils）。
+本仓库使用 **[Jujutsu (jj)](https://jj-vcs.dev/)** 作为版本控制系统（纯 jj 模式，无 `.git` 目录）。
+
+### 常用 jj 命令对照
+
+| 操作 | jj 命令 |
+|------|---------|
+| 查看历史 | `jj log` / `jj log 'all()'` |
+| 查看状态 | `jj status` |
+| 新建提交 | `jj commit` |
+| 创建新变更 | `jj new` |
+| 变基 | `jj rebase` |
+| 合并提交 | `jj squash` |
+| 撤销操作 | `jj undo` |
+| 查看标签 | `jj tag list` |
+| 查看分支 | `jj bookmark list` |
+| 推送远端 | `jj git push` |
+| 拉取远端 | `jj git fetch` |
+
+### 注意事项
+- 本仓库为**纯 jj 模式**，无 `.git` 目录；本地不要使用 `git` 命令
+- CI/CD（Gitea Actions）仍通过 Git 协议拉取代码，Runner 侧自动使用 `git`，无需修改
+- 检查标签是否存在时使用 `jj log --no-graph --revisions "tag(${tag})"` 而非 `git rev-parse`
+
+## 提交 / 推送硬规则（优先于下文）
+
+**每次提交和推送前必须执行以下检查，无论是否明确「发版」：**
+
+1. 涉及 `crates/**`、根目录 `Cargo.toml`/`Cargo.lock`、`secrets-mcp` 行为变更的提交，默认视为**需要发版**，除非明确说明「本次不发版」。
+2. 提交前检查 `crates/secrets-mcp/Cargo.toml` 的 `version`，再查 tag：`jj tag list`。若当前版本对应 tag 已存在且有代码变更，**必须 bump 版本号**并 `cargo build` 同步 `Cargo.lock`。
+3. 提交前运行 `./scripts/release-check.sh`（版本/tag + `fmt` + `clippy --locked` + `test --locked`）。若脚本不存在或不可用，至少运行 `cargo fmt -- --check && cargo clippy --locked -- -D warnings && cargo test --locked`。

-- **连接串**: `postgres://postgres:<password>@<host>:<port>/secrets`
-- **表**: `secrets`（主表）+ `audit_log`（审计表）+ `kv_config`（Argon2 salt 等），首次连接自动建表（auto-migrate）
+- **建议库名**：`secrets-mcp`（专用实例，与历史库名区分）。
+- **连接**：环境变量 **`SECRETS_DATABASE_URL`**（本分支无本地配置文件路径）。
+- **表**：`entries`（含 `user_id`）、`secrets`、`entries_history`、`secrets_history`、`audit_log`、`users`、`oauth_accounts`，首次连接 **auto-migrate**（`secrets-core` 的 `migrate`）。
+- **Web 会话**：与上项 **同一数据库 URL**；`secrets-mcp` 启动时对 tower-sessions 的 PostgreSQL 存储 **auto-migrate**（会话表与业务表共存于该实例，无需第二套连接串）。

-### 字段职责划分
+### audit_log / history
 
-| 字段 | 存什么 | 示例 |
-|------|--------|------|
-| `namespace` | 项目/团队隔离 | `refining`, `ricnsmart` |
-| `kind` | 记录类型 | `server`, `service` |
-| `name` | 唯一标识名 | `i-uf63f2uookgs5uxmrdyc`, `gitea` |
-| `tags` | 多维分类标签 | `["aliyun","hongkong","ricn"]` |
-| `metadata` | 明文非敏感信息 | `{"ip":"47.243.154.187","desc":"Grafana","domains":["..."]}` |
-| `encrypted` | 敏感凭据，AES-256-GCM 加密存储 | 二进制密文，解密后为 `{"ssh_key":"...","password":"..."}` |
+与迁移脚本一致：`audit_log`、`entries_history`、`secrets_history` 用于审计与时间旅行恢复；字段定义见 `crates/secrets-core/src/db.rs` 内 `migrate` SQL。`audit_log` 含可选 **`user_id`**（多租户下标识操作者；可空以兼容遗留数据）。`audit_log` 中普通业务事件使用 **`folder` / `type` / `name`** 对应 entry 坐标；登录类事件固定使用 **`folder='auth'`**，此时 `type`/`name` 表示认证目标而非 entry 身份。
 
-## 数据库配置
+### MCP 消歧（AI 调用）
 
-首次使用需显式配置数据库连接，设置一次后在该设备上持久生效：
+按 `name` 定位条目的工具（`secrets_update` / `secrets_history` / `secrets_rollback` / `secrets_delete` 单条模式）：若该用户下仅一条匹配则直接执行；若多条（同 `name`、不同 `folder`）则返回错误并提示补全 `folder`。也可直接传 `id`（UUID）跳过消歧。
 
-```bash
-secrets config set-db "postgres://postgres:<password>@<host>:<port>/secrets"
-secrets config show   # 查看当前配置（密码脱敏）
-secrets config path   # 打印配置文件路径
-```
+注意：`secrets_get` 只接受 UUID `id`（来自 `secrets_find` 结果），不支持按 `name` 定位。
 
-`set-db` 会先验证连接可用，成功后才写入配置文件；连接失败时提示 "Database connection failed" 且不修改配置。
+### 字段职责
 
-配置文件：`~/.config/secrets/config.toml`，权限 0600。`--db-url` 参数可一次性覆盖。
+| 字段 | 含义 | 示例 |
+|------|------|------|
+| `folder` | 隔离空间（参与唯一键） | `refining` |
+| `type` | 软分类（不参与唯一键，用户自定义） | `server`, `service`, `account`, `person`, `document` |
+| `name` | 标识名 | `gitea`, `aliyun` |
+| `notes` | 非敏感说明 | 自由文本 |
+| `tags` | 标签 | `["aliyun","prod"]` |
+| `metadata` | 明文描述 | `ip`、`url`、`subtype` |
+| `secrets.name` | 密钥名称（调用方提供） | `token`, `ssh_key`, `password` |
+| `secrets.type` | 密钥类型（调用方提供，默认 `text`） | `text`, `password`, `key` |
+| `secrets.encrypted` | 密文 | AES-GCM |
 
-## 主密钥与加密
+### 共享密钥（N:N 关联）
 
-首次使用（每台设备各执行一次）：
-
-```bash
-secrets config set-db "postgres://postgres:<password>@<host>:<port>/secrets"
-secrets init   # 提示输入主密码，Argon2id 派生主密钥后存入 OS 钥匙串
-```
-
-主密码不存储；salt 存于 `kv_config`，首台设备生成后共享，确保同一主密码在所有设备派生出相同主密钥。
-
-主密钥存储后端：macOS Keychain、Windows Credential Manager、Linux keyutils（会话级，重启后需再次 `secrets init`）。
-
-**从旧版（明文 JSONB）升级**：升级后执行 `secrets init` 即可（明文记录需手动重新 add 或通过 update 更新）。
-
-## CLI 命令
-
-### AI 使用主路径
-
-**读取一律用 `search`，写入用 `add` / `update`，避免反复查帮助。**
-
-输出格式规则：
-- TTY（终端直接运行）→ 默认 `text`
-- 非 TTY（管道/重定向/AI 调用）→ 自动 `json-compact`
-- 显式 `-o json` → 美化 JSON
-- 显式 `-o env` → KEY=VALUE（可 source）

 ## 代码规范
 
-- 错误处理：统一使用 `anyhow::Result`，不用 `unwrap()`
-- 异步：全程 `tokio`，数据库操作 `sqlx` async
-- SQL：使用 `sqlx::query` / `sqlx::query_as` 绑定参数，禁止字符串拼接（搜索的动态 WHERE 子句除外，需使用参数绑定 `$1/$2`）
-- 新增 `kind` 类型时：只需在 `add` 调用时传入，无需改代码
-- 字段命名：CLI 短标志 `-n`=namespace，`-m`=meta，`-s`=secret，`-q`=query，`-v`=verbose，`-f`=field，`-o`=output
-- 日志：用户可见输出用 `println!`；调试/运维信息用 `tracing::debug!`/`info!`/`warn!`/`error!`
-- 审计：`add`/`update`/`delete` 成功后调用 `audit::log_tx`，写入 `audit_log` 表；失败只 warn 不中断
-- 加密：`encrypted` 列存储 AES-256-GCM 密文；`add`/`update`/`search`/`delete` 需主密钥（`secrets init` 后从 OS 钥匙串加载）
-- 输出：读命令通过 `OutputMode` 支持 text/json/json-compact/env；写命令 `add` 同样支持 `-o json`
+- 错误：业务层 `anyhow::Result`，避免生产路径 `unwrap()`。
+- 异步：`tokio` + `sqlx` async。
+- SQL：`sqlx::query` / `query_as` 参数绑定；动态 WHERE 仍须用占位符绑定。
+- 日志：运维用 `tracing`；面向用户的 Web 响应走 axum handler。tracing 字段风格：变量名即字段名时用简写（`%var`、`?var`、`var`），否则用显式形式（`field = %expr`）。
+- 审计：写操作成功后尽量 `audit::log_tx`；失败可 `warn`，不掩盖主错误。
+- 加密：密钥由用户密码短语通过 **PBKDF2-SHA256（600k 次）** 在客户端派生，服务端只存 `key_salt`/`key_check`/`key_params`，不持有原始密钥。Web 客户端在浏览器本地完成加解密；MCP 客户端通过 `X-Encryption-Key` 请求头传递密钥，服务端临时解密后返回明文。
+- MCP：tools 参数与 JSON Schema（`schemars`）保持同步，鉴权以请求扩展中的用户上下文为准。
 
-## 提交前检查（必须全部通过）
+## 生产 CORS
 
-每次提交代码前，请在本地依次执行以下检查，**全部通过后再 push**：
+生产环境 CORS 使用显式请求头白名单（`build_cors_layer`），而非 `allow_headers(Any)`，
+因为 `tower-http` 禁止 `allow_credentials(true)` 与 `allow_headers(Any)` 同时使用。
 
-优先使用：
+**维护约束**：若 MCP 协议或客户端新增自定义请求头，必须同步更新 `production_allowed_headers()`。
+当前允许的请求头：`Authorization`、`Content-Type`、`X-Encryption-Key`、`mcp-session-id`、`x-mcp-session`。
+
+## 提交前检查
 
 ```bash
 ./scripts/release-check.sh
 ```
 
-它等价于先检查版本号 / tag，再执行下面的格式、Lint、测试。
-
-### 1. 版本号（按需）
-
-若本次改动需要发版，请先确认 `Cargo.toml` 中的 `version` 已提升，避免 CI 打出的 Tag 与已有版本重复。**升级版本后需同时更新 `Cargo.lock`**（运行 `cargo build` 即可自动同步），否则 CI 中 `cargo clippy --locked` 会因 lock 与 manifest 不一致而失败。可通过 git tag 判断：
+或手动：
 
 ```bash
-# 查看当前 Cargo.toml 版本
-grep '^version' Cargo.toml
-
-# 查看是否已存在该版本对应的 tag（CI 使用格式 secrets-<version>）
-git tag -l 'secrets-*'
+cargo fmt -- --check
+cargo clippy --locked -- -D warnings
+cargo test --locked
 ```
 
-若当前版本已被 tag（例如已有 `secrets-0.3.0` 且 `Cargo.toml` 仍为 `0.3.0`），则应在 `Cargo.toml` 中 bump 版本号，再执行 `cargo build` 同步 `Cargo.lock`，最后一并提交，以便 CI 自动打新 Tag 并发布 Release。
-
-### 2. 格式、Lint、测试
+发版前确认未重复 tag：
 
 ```bash
-cargo fmt -- --check   # 格式检查（不通过则运行 cargo fmt 修复）
-cargo clippy -- -D warnings  # Lint 检查（消除所有 warning）
-cargo test             # 单元/集成测试
-```
-
-或一次性执行：
-
-```bash
-cargo fmt -- --check && cargo clippy -- -D warnings && cargo test
+grep '^version' crates/secrets-mcp/Cargo.toml
+jj tag list
 ```
 
 ## CI/CD
 
-- Gitea Actions（runners: debian / darwin-arm64 / windows）
-- 触发：`src/**`、`Cargo.toml`、`Cargo.lock` 变更推送到 main
-- 构建目标：`x86_64-unknown-linux-musl`、`aarch64-apple-darwin`、`x86_64-apple-darwin`（由 ARM mac runner 交叉编译）、`x86_64-pc-windows-msvc`
-- 新版本自动打 Tag（格式 `secrets-<version>`）并上传二进制与对应 `.sha256` 摘要到 Gitea Release
-- Release 仅在 Linux/macOS/Windows 构建全部成功后才会从 draft 发布
-- 通知：飞书 Webhook（`vars.WEBHOOK_URL`）
-- 所需 secrets/vars：`RELEASE_TOKEN`（Release 上传，Gitea PAT）、`vars.WEBHOOK_URL`（通知，可选）
-- **注意**：Gitea Actions 的 Secret/Variable 创建时，`data`/`value` 字段需传入**原始值**，不要使用 base64 编码
+- **触发**：任意分支 `push`，且路径含 `crates/**`、`deploy/**`、根目录 `Cargo.toml`、`Cargo.lock`、`.gitea/workflows/**`（见 `.gitea/workflows/secrets.yml`）。
+- **版本与 tag**：从 `crates/secrets-mcp/Cargo.toml` 读版本；构建成功后打 `secrets-mcp-<version>`：若远端已存在同名 tag，CI 会先删后于**当前提交**重建并推送（覆盖式发版）。
+- **质量与构建**：`fmt` / `clippy --locked` / `test --locked` → `x86_64-unknown-linux-musl` 发布构建 `secrets-mcp`。
+- **Release（可选）**：`secrets.RELEASE_TOKEN`（Gitea PAT）用于通过 API **创建或更新**该 tag 的 Release（非 draft）、上传 `tar.gz` + `.sha256`；未配置则跳过 API Release，仅 tag + 构建。
+- **部署（可选）**：仅 `main`、`feat/mcp`、`mcp` 分支在构建成功时跑 `deploy-mcp`；需 `vars.DEPLOY_HOST`、`vars.DEPLOY_USER`、`secrets.DEPLOY_SSH_KEY`。勿把 OAuth/DB 等写进 workflow，用 `deploy/.env.example` 在目标机配置。
+- **Secrets 写法**：Actions **secrets 须为原始值**（PEM、PAT 明文），**勿** base64；否则 SSH/Release 会失败。**勿**在 CI 中保存 `GOOGLE_CLIENT_SECRET`、DB 密码。
+- **通知**：`vars.WEBHOOK_URL`（可选，飞书）。

-跨设备密钥与配置管理 CLI，基于 Rust + PostgreSQL 18。
-
-将服务器信息、服务凭据统一存入数据库，供本地工具和 AI 读取上下文。敏感数据（`encrypted` 字段）使用 AES-256-GCM 加密存储，主密钥由 Argon2id 从主密码派生并存入系统钥匙串。
+Workspace：**`secrets-core`** + **`secrets-mcp`**（HTTP Streamable MCP + Web）。多租户密钥与元数据存 PostgreSQL；用户通过 **Google OAuth** 登录，**API Key** 鉴权 MCP 请求；秘密数据用**用户密码短语派生的密钥**在客户端加密，服务端不持有原始密钥。
 
 ## 安装
 
 ```bash
-cargo build --release
-# 或从 Release 页面下载预编译二进制
+cargo build --release -p secrets-mcp
+# 产物: target/release/secrets-mcp
 ```
 
-已有旧版本时，可执行 `secrets upgrade` 自动下载最新版并替换。该命令会校验 Release 附带的 `.sha256` 摘要后再安装。
+发版产物见 Gitea Release（tag：`secrets-mcp-<version>`，Linux musl 预编译）；其它平台本地 `cargo build`。
 
-## 首次使用（每台设备各执行一次）
+## 环境变量与本地运行
+
+复制 `deploy/.env.example` 为项目根目录 `.env`（已在 `.gitignore`），或导出同名变量：
+
+| 变量 | 说明 |
+|------|------|

+| `SECRETS_MCP_BIND` | 监听地址，默认 `127.0.0.1:9315`。容器内或直接对外暴露端口时请改为 `0.0.0.0:9315`；反代时常为 `127.0.0.1:9315`。 |
+| `GOOGLE_CLIENT_ID` / `GOOGLE_CLIENT_SECRET` | 可选；不配置则无 Google 登录入口。运行时从环境读取，勿写入 CI、勿打入二进制。 |
+| `RUST_LOG` | 可选；日志级别，如 `secrets_mcp=debug`。 |
+| `SECRETS_DATABASE_POOL_SIZE` | 可选。连接池最大连接数，默认 `10`。 |
+| `SECRETS_DATABASE_ACQUIRE_TIMEOUT` | 可选。获取连接超时秒数，默认 `5`。 |
+| `RATE_LIMIT_GLOBAL_PER_SECOND` | 可选。全局限流速率，默认 `100` req/s。 |

 ```bash
-# 1. 配置数据库连接（会先验证连接可用再写入）
-secrets config set-db "postgres://postgres:<password>@<host>:<port>/secrets"
-
-# 2. 初始化主密钥（提示输入至少 8 位的主密码，派生后存入 OS 钥匙串）
-secrets init
+cargo run -p secrets-mcp
 ```
 
-主密码不会存储，仅用于派生主密钥，且至少需 8 位。同一主密码在所有设备上会得到相同主密钥（salt 存于数据库，首台设备生成后共享）。
-
-**主密钥存储**：macOS → Keychain；Windows → Credential Manager；Linux → keyutils（会话级，重启后需再次 `secrets init`）。
-
-**从旧版（明文存储）升级**：升级后首次运行需执行 `secrets init` 即可（明文记录需手动重新 add 或通过 update 更新）。

-这个 CLI 以 AI 使用优先设计。核心路径只有一条：**读取用 `search`，写入用 `add` / `update`**。
-
-### 第一步：发现有哪些数据
+生产推荐示例（PostgreSQL TLS）：
 
 ```bash
-# 列出所有记录摘要（默认最多 50 条，安全起步）
-secrets search --summary --limit 20
-
-# 按 namespace 过滤
-secrets search -n refining --summary --limit 20
-
-# 按最近更新排序
-secrets search --sort updated --limit 10 --summary
+SECRETS_DATABASE_URL=postgres://postgres:***@db.refining.ltd:5432/secrets-mcp
+SECRETS_DATABASE_SSL_MODE=verify-full
+SECRETS_DATABASE_SSL_ROOT_CERT=/etc/secrets/pg-ca.crt
+SECRETS_ENV=production
 ```
 
-`--summary` 只返回轻量字段（namespace、kind、name、tags、desc、updated_at），不含完整 metadata 和 secrets。
+- **Web**：`BASE_URL`（登录、Dashboard、设置密码短语、创建 API Key）。
+- **MCP**：Streamable HTTP 基址 `{BASE_URL}/mcp`，需 `Authorization: Bearer <api_key>` + `X-Encryption-Key: <hex>` 请求头（读密文工具须带密钥）。
 
-### 第二步：精确读取单条记录
+## PostgreSQL TLS 加固
 
-```bash
-# 精确定位（namespace + kind + name 三元组）
-secrets search -n refining --kind service --name gitea
+- 推荐将数据库域名单独设置为 `db.refining.ltd`，服务域名保持 `secrets.refining.app`。
+- 数据库证书建议使用可校验链路（如 Let's Encrypt 或私有 CA），并保证证书 `SAN` 包含 `db.refining.ltd`。
+- PostgreSQL 侧建议使用 `hostssl` 规则限制应用来源（如 `47.238.146.244/32`），逐步移除公网明文 `host` 访问。
+- 应用端推荐 `SECRETS_DATABASE_SSL_MODE=verify-full`；仅在过渡阶段可临时用 `verify-ca`。
+- 可执行运维步骤见 [`deploy/postgres-tls-hardening.md`](deploy/postgres-tls-hardening.md)。
 
-# 获取完整记录（secrets 保持加密占位）
-secrets search -n refining --kind service --name gitea -o json
+## MCP 与 AI 工作流（v0.3+）
 
-# 直接提取单个 metadata 字段值（最短路径）
-secrets search -n refining --kind service --name gitea -f metadata.url
+条目在逻辑上以 **`(folder, name)`** 在用户内唯一（数据库唯一索引：`user_id + folder + name`）。同名可在不同 folder 下各存一条（例如 `refining/aliyun` 与 `ricnsmart/aliyun`）。
 
-# 同时提取多个 metadata 字段
-secrets search -n refining --kind service --name gitea \
-  -f metadata.url -f metadata.default_org
+### 工具列表
 
-# 需要 secrets 时，改用 inject / run
-secrets inject -n refining --kind service --name gitea
-secrets run -n refining --kind service --name gitea -- printenv
+| 工具 | 需要加密密钥 | 说明 |
+|------|-------------|------|
+| `secrets_find` | 否 | 发现条目（返回含 secret_fields schema），支持 `name_query` 模糊匹配 |
+| `secrets_search` | 否 | 搜索条目，支持 `query`/`folder`/`type`/`name` 过滤、`sort`/`offset` 分页、`summary` 摘要模式 |
+| `secrets_get` | 是 | 按 UUID `id` 获取单条条目及解密后的 secrets |
+| `secrets_add` | 是 | 添加新条目，支持 `meta_obj`/`secrets_obj` JSON 对象参数、`secret_types` 指定密钥类型、`link_secret_names` 关联已有 secret |
+| `secrets_update` | 是 | 更新条目，支持 `id` 或 `name`+`folder` 定位 |
+| `secrets_delete` | 否 | 删除条目，支持 `id` 或 `name`+`folder` 定位；`dry_run=true` 预览删除 |
+| `secrets_history` | 否 | 查看条目历史，支持 `id` 或 `name`+`folder` 定位 |
+| `secrets_rollback` | 是 | 回滚条目到指定历史版本，支持 `id` 或 `name`+`folder` 定位 |
+| `secrets_export` | 是 | 导出条目（含解密明文），支持 JSON/TOML/YAML 格式 |
+| `secrets_env_map` | 是 | 将 secrets 转换为环境变量映射（`UPPER(entry)_UPPER(field)` 格式），支持 `prefix` |
+| `secrets_overview` | 否 | 返回各 folder 和 type 的 entry 计数概览 |
+
+### 消歧规则
+
+- **按 `name` 定位的工具**（`secrets_update` / `secrets_delete` / `secrets_history` / `secrets_rollback`）：若该用户下仅一条匹配则直接执行；若多条（同 `name`、不同 `folder`）则返回错误并提示补全 `folder`。也可直接传 `id`（UUID）跳过消歧。
+- **`secrets_get`** 仅支持通过 `id`（UUID）获取。
+- **`secrets_delete`** 的 `dry_run=true` 与真实删除使用相同消歧规则——唯一则预览一条，多条则报错并要求 `folder`。
+
+### 共享密钥
+
+N:N 关联下，删除 entry 仅解除关联，被共享的 secret 若仍被其他 entry 引用则保留；无引用时自动清理。
+
+## 加密架构（混合 E2EE）
+
+### 密钥派生
+
+用户在 Web Dashboard 设置**密码短语**，浏览器使用 **Web Crypto API（PBKDF2-SHA256，600k 次迭代）**在本地派生 256-bit AES 密钥。
+
+- **Salt（32B）**：首次设置时在浏览器生成，存入服务端 `users.key_salt`
+- **key_check**：派生密钥加密已知常量 `"secrets-mcp-key-check"`，存入 `users.key_check`，用于登录时验证密码短语
+- **服务端不存储原始密钥**，只存 salt + key_check
+
+跨设备同步：新设备登录 → 输入相同密码短语 → 从服务端取 salt → 同样的 PBKDF2 → 得到相同密钥。
+
+### 写入与读取流程

-`search` 只负责发现、定位和读取 metadata，不直接展示 secrets。
+### 两种客户端对比
 
-### 输出格式
+| | Web 浏览器 | AI 客户端（MCP） |
+|---|---|---|
+| 密钥位置 | 仅在浏览器内存 / sessionStorage | MCP 配置 headers 中 |
+| 加解密位置 | 客户端（真正 E2E） | 服务端临时（请求级生命周期） |
+| 安全边界 | 服务端零知识 | 依赖 TLS + 服务端内存隔离 |
 
-| 场景 | 推荐命令 |
-|------|----------|
-| AI 解析 / 管道处理 | `-o json` 或 `-o json-compact` |
-| 写入 metadata `.env` 文件 | `-o env` |
-| 注入 secrets 到环境变量 | `inject` / `run` |
-| 人类查看 | 默认 `text`（TTY 下自动启用） |
-| 非 TTY（管道/重定向） | 自动 `json-compact` |
+### 敏感数据传输
 
-说明：`text` 输出中的时间会按当前机器本地时区显示；`json/json-compact` 继续使用 UTC（RFC3339 风格）以便脚本和 AI 稳定解析。
+- **OAuth `client_secret`** 只存服务端环境变量，不发给浏览器
+- **API Key** 当前存放在 `users.api_key`，Dashboard 会明文展示并可重置
+- **X-Encryption-Key** 随 MCP 请求经 TLS 传输，服务端仅在请求处理期间持有（不持久化）
+- **生产环境必须走 HTTPS/TLS**
 
-```bash
-# 管道直接 jq 解析（非 TTY 自动 json-compact）
-secrets search -n refining --kind service | jq '.[].name'
+## AI 客户端配置
 
-# 导出 metadata 为可 source 的 env 文件（单条记录）
-secrets search -n refining --kind service --name gitea -o env \
-  > ~/.config/gitea/config.env
+在 Web Dashboard 设置密码短语后，解锁页面会按客户端格式生成配置。常见客户端示例如下：
 
-# 需要 secrets 时，使用 inject / run
-secrets inject -n refining --kind service --name gitea > ~/.config/gitea/secrets.env
-secrets run -n refining --kind service --name gitea -- ./deploy.sh

 ## 数据模型
 
-单张 `secrets` 表，首次连接自动建表；同时自动创建 `audit_log` 表，记录所有写操作。
+主表 **`entries`**（`folder`、`type`、`name`、`notes`、`tags`、`metadata`，多租户时带 `user_id`）+ 子表 **`secrets`**（每行一个加密字段：`name`、`type`、`encrypted`，通过 `entry_secrets` 中间表与 entry 建立 N:N 关联）。**唯一性**：`UNIQUE(user_id, folder, name)`（`user_id` 为空时为遗留行唯一 `(folder, name)`）。另有 `entries_history`、`secrets_history`、`audit_log`，以及 **`users`**（含 `key_salt`、`key_check`、`key_params`、`api_key`）、**`oauth_accounts`**。首次连库自动迁移建表（`secrets-core` 的 `migrate`）；已有库在进程启动时亦由同一 `migrate()` 增量补齐表、索引与 N:N 结构。若需从更早版本对照一次性 SQL，可在 git 历史中检索已移除的 `scripts/migrate-v0.3.0.sql`。**Web 登录会话**（tower-sessions）使用同一 `SECRETS_DATABASE_URL`，进程启动时对会话存储执行迁移（见 `secrets-mcp` 中 `PostgresStore::migrate`），无需额外环境变量。
 
-| 字段 | 说明 |
-|------|------|
-| `namespace` | 一级隔离，如 `refining`、`ricnsmart` |
-| `kind` | 记录类型，如 `server`、`service`（可自由扩展） |
-| `name` | 人类可读唯一标识 |
-| `tags` | 多维标签，如 `["aliyun","hongkong"]` |
-| `metadata` | 明文描述信息（ip、desc、domains 等） |
-| `encrypted` | 敏感凭据（ssh_key、password、token 等），AES-256-GCM 加密存储 |
-
-`-m` / `--meta` 写入 `metadata`，`-s` / `--secret` 写入 `encrypted`。支持 `key=value`、`key=@file`、`key:=<json>`，也支持 `credentials:content@./key.pem` 这种嵌套字段文件写入语法，避免手动转义多行文本；删除时也支持 `--remove-secret credentials:content` 和 `--remove-meta credentials:content`。加解密使用主密钥（由 `secrets init` 设置）。
-
-### `-m` / `--meta` JSON 语法速查
-
-`-m` 和 `-s` 走的是同一套解析规则，只是写入位置不同：`-m` 写到明文 `metadata`，适合端口、开关、标签、描述性配置等非敏感信息。
-
-| 目标值 | 写法示例 | 实际存入 |
+| 位置 | 字段 | 说明 |
 |------|------|------|
-| 普通字符串 | `-m url=https://gitea.refining.dev` | `"https://gitea.refining.dev"` |
-| 文件内容字符串 | `-m notes=@./service-notes.txt` | `"..."` |
-| 布尔值 | `-m enabled:=true` | `true` |
-| 数字 | `-m port:=3000` | `3000` |
-| `null` | `-m deprecated_at:=null` | `null` |
-| 数组 | `-m domains:='["gitea.refining.dev","git.refining.dev"]'` | `["gitea.refining.dev","git.refining.dev"]` |
-| 对象 | `-m tls:='{"enabled":true,"redirect_http":true}'` | `{"enabled":true,"redirect_http":true}` |
-| 嵌套路径 + JSON | `-m deploy:strategy:='{"type":"rolling","batch":2}'` | `{"deploy":{"strategy":{"type":"rolling","batch":2}}}` |
+| entries | folder | 组织/隔离空间，如 `refining`、`ricnsmart`；参与唯一键 |
+| entries | type | 软分类，用户自定义，如 `server`、`service`、`account`、`person`、`document`（不参与唯一键） |
+| entries | name | 人类可读标识；与 `folder` 一起在用户内唯一 |
+| entries | notes | 非敏感说明文本 |
+| entries | metadata | 明文 JSON（ip、url、subtype 等） |
+| secrets | name | 密钥名称（调用方提供） |
+| secrets | type | 密钥类型（调用方提供，默认 `text`） |
+| secrets | encrypted | AES-GCM 密文（含 nonce） |
+| users | key_salt | PBKDF2 salt（32B），首次设置密码短语时写入 |
+| users | key_check | 派生密钥加密已知常量，用于验证密码短语 |
+| users | key_params | 派生算法参数，如 `{"alg":"pbkdf2-sha256","iterations":600000}` |
 
-常见规则：
+### 共享密钥（N:N 关联）
 
-- `=` 表示按字符串存储。
-- `:=` 表示按 JSON 解析。
-- shell 中数组和对象建议整体用单引号包住。
-- 嵌套字段继续用冒号分隔：`-m runtime:max_open_conns:=20`。
+多个条目可共享同一密文字段，通过 `entry_secrets` 中间表实现 N:N 关联：
+- 添加条目时可通过 `link_secret_names` 参数关联已有的 secret（按 `(user_id, name)` 精确匹配查找）
+- 同一 secret 可被多个 entry 引用，删除某 entry 不会级联删除被共享的 secret
+- 当 secret 不再被任何 entry 引用时，自动清理（`NOT EXISTS` 子查询）
 
-示例：新增一条带 typed metadata 的记录
+### 类型（Type）
 
-```bash
-secrets add -n refining --kind service --name gitea \
-  -m url=https://gitea.refining.dev \
-  -m port:=3000 \
-  -m enabled:=true \
-  -m domains:='["gitea.refining.dev","git.refining.dev"]' \
-  -m tls:='{"enabled":true,"redirect_http":true}'
-```
-
-示例：更新已有记录中的嵌套 metadata
-
-```bash
-secrets update -n refining --kind service --name gitea \
-  -m deploy:strategy:='{"type":"rolling","batch":2}' \
-  -m runtime:max_open_conns:=20
-```
-
-### `-s` / `--secret` JSON 语法速查
-
-当你希望写入的不是普通字符串，而是 `true`、`123`、`null`、数组或对象时，用 `:=`，右侧按 JSON 解析。
-
-| 目标值 | 写法示例 | 实际存入 |
-|------|------|------|
-| 普通字符串 | `-s token=abc123` | `"abc123"` |
-| 文件内容字符串 | `-s ssh_key=@./id_ed25519` | `"-----BEGIN ..."` |
-| 布尔值 | `-s enabled:=true` | `true` |
-| 数字 | `-s retry_count:=3` | `3` |
-| `null` | `-s deprecated_at:=null` | `null` |
-| 数组 | `-s scopes:='["repo","workflow"]'` | `["repo","workflow"]` |
-| 对象 | `-s extra:='{"region":"ap-east-1","verify_tls":true}'` | `{"region":"ap-east-1","verify_tls":true}` |
-| 嵌套路径 + JSON | `-s auth:policy:='{"mfa":true,"ttl":3600}'` | `{"auth":{"policy":{"mfa":true,"ttl":3600}}}` |
-
-常见规则：
-
-- `=` 表示按字符串存储，不做 JSON 解析。
-- `:=` 表示按 JSON 解析，适合布尔、数字、数组、对象、`null`。
-- shell 里对象和数组通常要整体加引号，推荐单引号：`-s flags:='["a","b"]'`。
-- 嵌套字段继续用冒号分隔：`-s credentials:enabled:=true`。
-- 如果你就是想存一个“JSON 字符串字面量”，可以写成 `-s note:='"hello"'`，但大多数字符串场景直接用 `=` 更直观。
-
-示例：新增一条同时包含字符串、文件、布尔、数组、对象的记录
-
-```bash
-secrets add -n refining --kind service --name deploy-bot \
-  -s token=abc123 \
-  -s ssh_key=@./keys/deploy-bot.pem \
-  -s enabled:=true \
-  -s scopes:='["repo","workflow"]' \
-  -s policy:='{"ttl":3600,"mfa":true}'
-```
-
-示例：更新已有记录中的嵌套 JSON 字段
-
-```bash
-secrets update -n refining --kind service --name deploy-bot \
-  -s auth:config:='{"issuer":"gitea","rotate":true}' \
-  -s auth:retry:=5
-```
+`type` 字段用于软分类，由用户自由填写，不做任何自动转换或归一化。常见示例：`server`、`service`、`account`、`person`、`document`，但任何值均可接受。
 
 ## 审计日志
 
-`add`、`update`、`delete` 操作成功后自动向 `audit_log` 表写入一条记录，包含操作类型、操作对象和变更摘要（不含 secret 值）。操作者取自 `$USER` 环境变量。
+`add`、`update`、`delete` 等写操作写入 **`audit_log`**（操作类型、对象、摘要，不含 secret 明文）。多租户场景下可写 **`user_id`**（可空，兼容遗留行）。
+业务条目事件使用 **`folder` / `type` / `name`**；登录类事件使用 **`folder='auth'`**，此时 `type`/`name` 表示认证目标（例如 `oauth` / `google`），不表示某条 secrets entry。

 ## CI/CD（Gitea Actions）
 
-推送 `main` 分支时自动：fmt/clippy/test 检查 → Linux/macOS/Windows 构建 → 上传二进制与 `.sha256` 摘要 → 所有平台成功后发布 Release。
+见 [`.gitea/workflows/secrets.yml`](.gitea/workflows/secrets.yml)。
 
-**首次使用需配置 Actions 变量和 Secrets：**
+- **触发**：任意分支 `push`，且变更路径包含 `crates/**`、`deploy/**`、根目录 `Cargo.toml` / `Cargo.lock`、`.gitea/workflows/**`。
+- **流水线**：解析 `crates/secrets-mcp/Cargo.toml` 版本 → `cargo fmt` / `clippy --locked` / `test --locked` → 交叉编译 `x86_64-unknown-linux-musl` 的 `secrets-mcp` → 构建成功后打 tag `secrets-mcp-<version>`（若远端已存在同名 tag，会先删除再于**当前提交**重建并推送，覆盖式发版）。
+- **Release（可选）**：配置仓库 Secret `RELEASE_TOKEN`（Gitea PAT，明文勿 base64）时，会通过 API **创建或更新**已指向该 tag 的 Release（非 draft）、上传 `tar.gz` 与 `.sha256`；未配置则跳过 API Release，仅 tag + 构建结果。
+- **部署（可选）**：仅在 `main`、`feat/mcp` 或 `mcp` 分支且构建成功时，若已配置 `vars.DEPLOY_HOST`、`vars.DEPLOY_USER` 与 `secrets.DEPLOY_SSH_KEY`，则 `deploy-mcp` 通过 SCP/SSH 更新目标机二进制并 `systemctl restart secrets-mcp`。
+- **通知（可选）**：`vars.WEBHOOK_URL` 为飞书 Webhook 时，构建/部署/发布节点会推送简要状态。
 
 ```bash
-# 需有 ~/.config/gitea/config.env（GITEA_URL、GITEA_TOKEN、GITEA_WEBHOOK_URL）
-./scripts/setup-gitea-actions.sh
+./scripts/setup-gitea-actions.sh   # 通过 Gitea API 写入 RELEASE_TOKEN、WEBHOOK_URL、部署相关变量等

+# Secrets MCP
+
+> 给 AI 与自动化工具的简要说明。本站是 **secrets-mcp**：Streamable HTTP **MCP**（Model Context Protocol）与 **Web 控制台** 的组合，用于在多租户场景下存储条目元数据与加密后的秘密字段；持久化在 PostgreSQL。用户通过 OAuth（如已配置）登录 Web；MCP 调用使用 API Key 与加密相关请求头。
+
+## 公开页面
+
+- **`/`**：公开首页，说明安全架构（客户端密钥派生、密文存储、多租户与审计等），无需登录。
+
+## 不应抓取或索引的内容
+
+- **`/mcp`**：MCP 流式 HTTP 端点（JSON-RPC 等），**不是** HTML 文档，也不适合作为公开知识库来源。
+- **`/api/*`**：会话或 API Key 相关的 HTTP API。
+- **`/login`**：登录入口页（`noindex` / robots 通常 disallow）。
+- **`/dashboard`、`/audit`、`/auth/*`、`/account/*`**：需浏览器会话，属于用户私有界面与 OAuth 流程。
+
+## 给 AI 助手的实用提示
+
+- 向用户说明连接方式时：MCP 基址为 `{BASE_URL}/mcp`（`BASE_URL` 由部署方设置），通常需要 `Authorization: Bearer <api_key>`；读写加密秘密时还需按部署文档传递 `X-Encryption-Key` 等头（与客户端模式有关）。
+- **不要编造**本实例的数据库 URL、OAuth 密钥、回调地址或任何凭据；一律以用户环境变量与运维文档为准。
+- Web 端在浏览器内用密码短语派生密钥完成端到端加密；MCP 路径下服务端可能在请求周期内临时使用客户端提供的密钥处理密文（架构细节见项目 README「加密架构」）。
+
+## 延伸阅读
+
+- 源码仓库：<https://gitea.refining.dev/refining/secrets>（`README.md`、`AGENTS.md` 含环境变量、表结构与运维约定）。
+
+## 关于本文件
+
+- 遵循常见的 **`/llms.txt`** 约定，便于人类与 LLM 快速了解站点性质与抓取边界；同文可在 **`/ai.txt`** 获取。

+# PostgreSQL TLS Hardening Runbook
+
+This runbook applies to:
+
+- PostgreSQL server: `47.117.131.22` (`db.refining.ltd`)
+- `secrets-mcp` app server: `47.238.146.244` (`secrets.refining.app`)
+
+## 1) Issue certificate for `db.refining.ltd` (Let's Encrypt + Cloudflare DNS-01)
+
+Install `acme.sh` on the PostgreSQL server and use a Cloudflare API token with DNS edit permission for the target zone.
+
+```bash
+curl https://get.acme.sh | sh -s email=ops@refining.ltd
+export CF_Token="your_cloudflare_dns_token"
+export CF_Zone_ID="your_zone_id"
+~/.acme.sh/acme.sh --issue --dns dns_cf -d db.refining.ltd --keylength ec-256
+```
+
+Install cert/key into a PostgreSQL-readable path:
+
+```bash
+sudo mkdir -p /etc/postgresql/tls
+sudo ~/.acme.sh/acme.sh --install-cert -d db.refining.ltd --ecc \
+  --fullchain-file /etc/postgresql/tls/fullchain.pem \
+  --key-file /etc/postgresql/tls/privkey.pem \
+  --reloadcmd "systemctl reload postgresql || systemctl restart postgresql"
+sudo chown -R postgres:postgres /etc/postgresql/tls
+sudo chmod 600 /etc/postgresql/tls/privkey.pem
+sudo chmod 644 /etc/postgresql/tls/fullchain.pem
+```
+
+## 2) Configure PostgreSQL TLS and access rules
+
+In `postgresql.conf`:
+
+```conf
+ssl = on
+ssl_cert_file = '/etc/postgresql/tls/fullchain.pem'
+ssl_key_file = '/etc/postgresql/tls/privkey.pem'
+```
+
+In `pg_hba.conf`, allow app traffic via TLS only (example):
+
+```conf
+hostssl  secrets-mcp  postgres  47.238.146.244/32  scram-sha-256
+```
+
+Keep a safe admin path (`local` socket or restricted source CIDR) before removing old plaintext `host` rules.
+
+Reload PostgreSQL:
+
+```bash
+sudo systemctl reload postgresql
+```
+
+## 3) Verify server-side TLS
+
+```bash
+openssl s_client -starttls postgres -connect db.refining.ltd:5432 -servername db.refining.ltd
+```
+
+The handshake should succeed and the certificate should match `db.refining.ltd`.
+
+## 4) Update `secrets-mcp` app server env
+
+Use environment values like:
+
+```bash
+SECRETS_DATABASE_URL=postgres://postgres:***@db.refining.ltd:5432/secrets-mcp
+SECRETS_DATABASE_SSL_MODE=verify-full
+SECRETS_ENV=production
+```
+
+If you use private CA instead of public CA, also set:
+
+```bash
+SECRETS_DATABASE_SSL_ROOT_CERT=/etc/secrets/pg-ca.crt
+```
+
+Restart `secrets-mcp` after updating env.
+
+## 5) Verify from app server
+
+Run positive and negative checks:
+
+- Positive: app starts, migrations pass, dashboard + MCP API work.
+- Negative:
+  - wrong hostname -> connection fails
+  - wrong CA file -> connection fails
+  - disable TLS on DB -> connection fails
+
+This ensures no silent downgrade to weak TLS in production.
