Release secrets-mcp 0.3.0: folder/type schema and MCP folder disambiguation

- Rename namespace/kind to folder/type on entries, audit_log, and history tables;
  add notes. Unique key is (user_id, folder, name).
- Service layer and MCP tools support name-first lookup with optional folder when
  multiple entries share the same name.
- secrets_delete dry_run uses the same disambiguation as real deletes.
- Add scripts/migrate-v0.3.0.sql for manual DB migration. Refresh README and
  AGENTS.md.

+
+## 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：`git tag -l 'secrets-mcp-*'`。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`。

 ## 数据库
 
-- **Host**: `47.117.131.22:5432`（阿里云上海 ECS，PostgreSQL 18 with io_uring）
+- **建议库名**：`secrets-mcp`（专用实例，与历史库名区分）。
-- **Database**: `secrets`
+- **连接**：环境变量 **`SECRETS_DATABASE_URL`**（本分支无本地配置文件路径）。
-- **连接串**: `postgres://postgres:<password>@47.117.131.22:5432/secrets`
+- **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`）。
-- **表**: 单张 `secrets` 表，首次连接自动建表（auto-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）。

 ## 代码规范
 
-- 错误处理：统一使用 `anyhow::Result`，不用 `unwrap()`
+- 错误：业务层 `anyhow::Result`，避免生产路径 `unwrap()`。
-- 异步：全程 `tokio`，数据库操作 `sqlx` async
+- 异步：`tokio` + `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`）
+- SQL：`sqlx::query` / `query_as` 参数绑定；动态 WHERE 仍须用占位符绑定。
-- 新增 `kind` 类型时：只需在 `add` 调用时传入，无需改代码
+- 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`）。
-- 字段命名：CLI 短标志 `-n`=namespace，`-m`=meta，`-s`=secret，`-q`=query
+- 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）
+## 提交前检查
-
-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**：
-
-### 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。可通过 git tag 判断：
 
 ```bash
-# 查看当前 Cargo.toml 版本
+./scripts/release-check.sh
-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-*'
 ```
 
-若当前版本已被 tag（例如已有 `secrets-0.1.0` 且 `Cargo.toml` 仍为 `0.1.0`），则应在 `Cargo.toml` 中 bump 版本号后再提交，以便 CI 自动打新 Tag 并发布 Release。
+或手动：
-
-### 2. 格式、Lint、测试
 
 ```bash
-cargo fmt -- --check   # 格式检查（不通过则运行 cargo fmt 修复）
+cargo fmt -- --check
-cargo clippy -- -D warnings  # Lint 检查（消除所有 warning）
+cargo clippy --locked -- -D warnings
-cargo test             # 单元/集成测试
+cargo test --locked
 ```
 
-或一次性执行：
+发版前确认未重复 tag：
 
 ```bash
-cargo fmt -- --check && cargo clippy -- -D warnings && cargo test
+grep '^version' crates/secrets-mcp/Cargo.toml
+git tag -l 'secrets-mcp-*'
 ```
 
 ## CI/CD
 
-- Gitea Actions（runner: debian）
+- **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`）。
-- 触发：`src/**`、`Cargo.toml`、`Cargo.lock` 变更推送到 main
+- **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）。
-- 构建目标：`x86_64-unknown-linux-musl`（静态链接，无 glibc 依赖）
+- **质量与构建**：`fmt` / `clippy --locked` / `test --locked` → `x86_64-unknown-linux-musl` 发布构建 `secrets-mcp`。
-- 新版本自动打 Tag（格式 `secrets-<version>`）并上传二进制到 Gitea Release
+- **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。
-- 通知：飞书 Webhook（`vars.WEBHOOK_URL`）
+- **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。
-- 所需 secrets/vars：`RELEASE_TOKEN`（Release 上传，Gitea PAT）、`vars.WEBHOOK_URL`（通知，可选）
+- **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）。

 ## 数据模型
 
-单张 `secrets` 表，首次连接自动建表。
+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：`field_name`、`encrypted`）。**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`）；已有库可对照 [`scripts/migrate-v0.3.0.sql`](scripts/migrate-v0.3.0.sql) 做列重命名与索引重建。**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 |
+| 位置 | 字段 | 说明 |
-|------|------|
+|------|------|------|
-| `namespace` | 一级隔离，如 `refining`、`ricnsmart` |
+| entries | folder | 组织/隔离空间，如 `refining`、`ricnsmart`；参与唯一键 |
-| `kind` | 记录类型，如 `server`、`service`（可自由扩展） |
+| entries | type | 软分类，如 `server`、`service`、`key`、`person`（可扩展，不参与唯一键） |
-| `name` | 人类可读唯一标识 |
+| entries | name | 人类可读标识；与 `folder` 一起在用户内唯一 |
-| `tags` | 多维标签，如 `["aliyun","hongkong"]` |
+| entries | notes | 非敏感说明文本 |
-| `metadata` | 明文描述信息（ip、desc、domains 等） |
+| entries | metadata | 明文 JSON（ip、url、`key_ref` 等） |
-| `encrypted` | 敏感凭据（ssh_key、password、token 等），MVP 阶段明文存储，预留加密字段 |
+| secrets | field_name | 明文字段名，便于 schema 展示 |
+| 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}` |
 
-`-m` / `--meta` 写入 `metadata`，`-s` / `--secret` 写入 `encrypted`，`value=@file` 从文件读取内容。
+### PEM 共享（`key_ref`）
+
+同一 PEM 可被多条 `server` 等记录引用：将 PEM 存为 **`type=key`** 的 entry，在其它条目的 `metadata.key_ref` 中写该 key 条目的 `name`；轮换时只更新 key 对应记录即可。
+
+## 审计日志
+
+`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。
+
+```sql
+SELECT action, folder, type, name, detail, user_id, created_at
+FROM audit_log
+ORDER BY created_at DESC
+LIMIT 20;
+```

 ## CI/CD（Gitea Actions）
 
-推送 `main` 分支时自动：fmt/clippy 检查 → musl 构建 → 创建 Release 并上传二进制。
+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   # 通过 Gitea API 写入 RELEASE_TOKEN、WEBHOOK_URL、部署相关变量等
-./scripts/setup-gitea-actions.sh
 ```
 
-- `RELEASE_TOKEN`（Secret）：Gitea PAT，用于创建 Release 上传二进制
+详见 [AGENTS.md](AGENTS.md)（发版规则、代码规范）。
-- `WEBHOOK_URL`（Variable）：飞书通知，可选

+# 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。
