feat(secrets-mcp): /changelog 页（Markdown 渲染）、首页与 Dashboard 入口

- 新增 CHANGELOG.md 构建嵌入、pulldown-cmark 渲染、路由 /changelog - 首页页脚与 MCP Dashboard 页脚提供变更记录链接；同步 README、AGENTS - 版本 secrets-mcp 0.5.24
docs: 同步 README/AGENTS — rollback 仅需 Bearer、env_map 命名规则、key_version 与 JSON 会话、导出 secret_types

+### Web 变更记录（`/changelog`）
+
+`crates/secrets-mcp/CHANGELOG.md` 在构建时嵌入，服务端以 **Markdown** 渲染为 HTML（`pulldown-cmark`）。**首页**（`/`）页脚与 **Dashboard**（`/dashboard`，MCP 配置页）页脚均提供「变更记录」链接；发版时随 `secrets-mcp` 版本更新该文件即可。
+
+### Web JSON API 与会话
+
+除页面路由使用的 `require_valid_user`（未登录或 `key_version` 与库不一致时重定向 `/login`）外，JSON API（`/api/...`）使用等价校验：会话中的 `key_version` 须与 `users.key_version` 一致，否则返回 **401** JSON，避免仅校验 `user_id` 时与页面行为不一致。
+
+### Web 条目页表格列（`/entries`）
+
+列表仅展示非敏感字段；**名称**与**操作**列为固定列（不可在「显示列」中关闭）。**文件夹**（对应 `entries.folder`）、类型、备注、标签、关联、密文等为**可选列**，由用户在「显示列」面板中勾选；可见性保存在浏览器 `localStorage`，键为 **`entries_col_vis`**。新增列会并入默认：若用户曾保存过旧版配置，缺失的列键会按当前默认补齐。**文件夹**列默认**显示**，便于在「全部」等跨 folder 视图下区分条目所属隔离空间。
+
+### 导出 / 导入文件
+
+JSON/TOML/YAML 导出可在每条目上包含 `secret_types`（secret 名 → `text` / `password` / `key` 等），导入时写回 `secrets.type`；**旧版导出无该字段**时导入仍成功，类型按 **`text`** 默认。
+
 ### 共享密钥（N:N 关联）

 多个 entry 可共享同一 secret 字段，通过 `entry_secrets` 中间表关联。

+# Code Review 修复计划
+
+**日期**: 2026-04-11  
+**来源**: 三份 code review 报告提炼合并  
+**范围**: 7 项修复 + 1 项风险提示（不纳入本次修复）
+
+---
+
+## 1. `secrets-core` 导入/导出链路
+
+**目标**: 修复"导入丢失 secret type"。
+
+**涉及文件**:
+- `crates/secrets-core/src/models.rs`
+- `crates/secrets-core/src/service/export.rs`
+- `crates/secrets-core/src/service/import.rs`
+
+**实施项**:
+1. 在 `ExportEntry` 增加可选字段 `secret_types: Option<BTreeMap<String, String>>`，键为 secret 名，值为 type。
+2. 修改导出逻辑，除了导出 `secrets` 的值，也把每个 secret 的 `type` 一并导出。
+3. 修改导入逻辑，把 `entry.secret_types` 传给 `AddParams.secret_types`，不再用 `&Default::default()`。
+4. 明确兼容旧导出文件：`secret_types` 缺失时继续默认 `"text"`。
+
+**验证**:
+1. 新增 round-trip 测试：带 `password` / `key` / `text` 三种类型的导出再导入，类型保持不变。
+2. 新增向后兼容测试：旧格式导入时仍成功，默认回落到 `"text"`。
+
+---
+
+## 2. `secrets-core` env map
+
+**目标**: 修复环境变量名碰撞。
+
+**涉及文件**:
+- `crates/secrets-core/src/service/env_map.rs`
+
+**实施项**:
+1. 统一分隔符策略：把字段名里的 `.` 替换成 `__`（双下划线），保留原始 `_` 为单下划线，避免 `db.password` 和 `db_password` 碰撞。
+2. 如仍发生碰撞，显式返回错误，而不是 `HashMap::insert` 静默覆盖。
+
+**验证**:
+1. 添加测试覆盖：
+   - `db.password` vs `db_password`
+   - 带 `prefix` 的情况
+   - 多 entry 合并时碰撞
+2. 确认输出变量名文档与实现一致。
+
+---
+
+## 3. `secrets-core` rollback
+
+**目标**: 修复回滚路径中的 TOCTOU 和"使用旧 live 值"问题。
+
+**涉及文件**:
+- `crates/secrets-core/src/service/rollback.rs`
+
+**实施项**:
+1. 把首次读取 live entry 的逻辑移入事务内，并与 `FOR UPDATE` 合并，避免在加锁前基于过期数据做决策。
+2. 在拿到加锁后的 live row 后，再决定错误消息、审计字段和更新语句输入。
+3. 明确回滚语义：
+   - 若产品希望"完全回到快照"，则 `name/notes` 也从快照恢复。
+   - 若希望保留当前标识，则代码和文档都要显式说明此设计决策。
+4. 避免混用事务前的 `live_entry` 与事务内的 `lr`。
+
+**验证**:
+1. 新增测试覆盖：
+   - 回滚时恢复字段是否符合预期
+   - 并发更新 + 回滚场景不再依赖过期值
+
+---
+
+## 4. `secrets-core` API key
+
+**目标**: 修复 `regenerate_api_key` 返回未持久化 key。
+
+**涉及文件**:
+- `crates/secrets-core/src/service/api_key.rs`
+
+**实施项**:
+1. 检查 `UPDATE` 的 `rows_affected()`。
+2. 若为 `0`，返回 `NotFoundUser` 或等价业务错误。
+3. 可选：改成 `UPDATE ... RETURNING api_key`，减少"先生成后判断"的分支。
+
+**验证**:
+1. 新增测试：
+   - 正常用户可返回新 key
+   - 不存在用户时返回错误，而不是返回伪成功 key
+
+---
+
+## 5. `secrets-mcp` tools
+
+**目标**: 修复 MCP 层三个问题：
+- `secrets_add` 提交后再回查 entry 的竞态
+- `secrets_find` 计数失败被吞成 0
+- `secrets_rollback` 冗余要求 encryption key
+
+**涉及文件**:
+- `crates/secrets-mcp/src/tools.rs`
+- 可能连带 `crates/secrets-core/src/service/add.rs` 的返回结构
+
+**实施项**:
+1. 让 `svc_add` 直接返回 `entry_id`，MCP 不再在提交后用 `name+folder+user_id` 二次 `resolve_entry`。
+2. `secrets_find` 中移除 `.unwrap_or(0)`：
+   - 要么把计数错误向上传播
+   - 要么返回 `total_count: null` / `count_unavailable: true`
+3. `secrets_rollback` 改为只要求用户身份，不要求 encryption key。
+4. 同步修正工具描述文案，避免 schema 与实际行为不一致。
+
+**验证**:
+1. `secrets_add`：父子关系新增时直接使用返回的 `entry_id`。
+2. `secrets_find`：模拟 count 失败时，结果不再伪装成 `0`。
+3. `secrets_rollback`：无 key 时可执行，工具描述与行为一致。
+
+---
+
+## 6. `secrets-mcp` Web 会话校验
+
+**目标**: 让 JSON API 与页面路由的 `key_version` 校验对齐。
+
+**涉及文件**:
+- `crates/secrets-mcp/src/web/mod.rs`
+- `crates/secrets-mcp/src/web/entries.rs`
+- `crates/secrets-mcp/src/web/account.rs`
+- 其他仅使用 `current_user_id()` 的 JSON handler
+
+**实施项**:
+1. 抽一个适用于 JSON API 的用户校验辅助函数。
+2. 该函数应同时完成：
+   - session 取 `user_id`
+   - 加载用户
+   - 比对 `SESSION_KEY_VERSION` 与 DB `key_version`
+3. 页面路由继续保留 `require_valid_user`，JSON 路由统一改用等价校验。
+4. 统一失败语义：
+   - HTML 路由：重定向 `/login`
+   - JSON 路由：返回 `401`
+
+**验证**:
+1. 新增测试覆盖：
+   - `key_version` 一致时 JSON API 正常
+   - `key_version` 不一致时 JSON API 返回 `401`
+   - 用户删除/会话损坏时返回正确错误
+
+---
+
+## 7. Web API 输入校验
+
+**目标**: 补齐 Web JSON API 的长度校验，避免 DB 约束错误落成 500。
+
+**涉及文件**:
+- `crates/secrets-mcp/src/web/entries.rs`
+- 如有需要，抽公共 helper 到 `web/mod.rs` 或单独模块
+
+**实施项**:
+1. 在 `api_entry_patch` 对齐 MCP 的长度规则：
+   - `folder <= 128`
+   - `type <= 64`
+   - `name <= 256`
+   - `notes <= 10000`
+2. 视情况复用 `validation` 常量，避免 Web/MCP 两套上限漂移。
+3. 保持错误返回为 `400`，而不是依赖数据库报错。
+
+**验证**:
+1. 为超长 `folder/type/name/notes` 分别补测试。
+2. 确认错误文案和现有本地化风格一致。
+
+---
+
+## 8. 暂不纳入本次修复（风险提示）
+
+- 调试日志记录加密密钥片段（`extract_enc_key_or_arg` 在 debug 级别记录 key 前后缀）
+- `encryption_key` 作为工具参数带来的日志/对话暴露面
+
+**处理方式**: 记录为"接口安全风险提示"，待后续单独决定是否收紧 debug 日志、调整工具描述或限制参数传 key 的路径。
+
+---
+
+## 实施顺序
+
+1. `secrets-core` 导入/导出链路
+2. `secrets-core` env map
+3. `secrets-core` rollback
+4. `secrets-core` API key
+5. `secrets-mcp` tools
+6. `secrets-mcp` Web 会话校验
+7. `secrets-mcp` Web 输入校验
+
+**原因**: 先修 core 语义和返回结构，再修上层接入。`svc_add` 返回结构、rollback 语义、export/import 格式都属于底层契约，适合先稳定。
+
+---
+
+## 验证与收尾
+
+1. 先跑相关单元/集成测试。
+2. 再跑全量：
+   ```bash
+   cargo fmt -- --check
+   cargo clippy --locked -- -D warnings
+   cargo test --locked
+   ```
+3. 若涉及 `crates/**` 的实际改动，按 `AGENTS.md` 约定检查版本/tag，并执行 `./scripts/release-check.sh`。

+# Code Review 修复方案合并计划
+
+**日期**: 2026-04-11  
+**来源**: 两个 AI 实现对比评估  
+**比较对象**:
+- `d7720662` (`/Users/voson/work/refining/secrets-cr-fixes-ws`)
+- `9f8a68cd` (`/Users/voson/work/refining/secrets/plan-impl`)
+
+---
+
+## 结论
+
+以 **`d7720662`** 为主线采纳。
+
+**原因**:
+1. `rollback` 的 live row 加锁与 snapshot 读取都在事务内完成，更符合原计划里对 TOCTOU 的修复要求。
+2. Web JSON API 的 session 校验保留了按 `UiLang` 返回错误信息的行为，没有把错误消息退化成固定英文。
+3. `svc_add` 返回 `entry_id`，MCP 层直接使用返回值建立 parent relation，和计划第 5 项更一致。
+
+---
+
+## 采纳策略
+
+### 1. 主线保留 `d7720662`
+
+保留以下实现，不从另一份实现回退：
+
+- `crates/secrets-core/src/service/rollback.rs`
+- `crates/secrets-mcp/src/web/mod.rs`
+- `crates/secrets-core/src/service/add.rs`
+- `crates/secrets-mcp/src/tools.rs`
+
+### 2. 从 `9f8a68cd` 手动吸收的小改动
+
+仅吸收下面两处，手动改写，不直接整文件 cherry-pick：
+
+1. `crates/secrets-mcp/src/web/entries.rs`
+   - 把长度校验报错文案改成基于 `crate::validation::*` 常量拼接，避免上限数字硬编码在文案里。
+
+2. `crates/secrets-core/src/service/env_map.rs`
+   - 补 `env_prefix_with_and_without_prefix` 单测。
+
+---
+
+## 明确不采纳的实现
+
+### 不采纳 `9f8a68cd` 的 `rollback.rs`
+
+原因：
+- 它仍然先在事务外读取 `entries_history`，再开启事务并锁 live row。
+- 对“回滚到最近快照”的路径仍存在先读后锁的时间窗口。
+
+### 不采纳 `9f8a68cd` 的 `web/mod.rs`
+
+原因：
+- `load_session_user_strict()` / `require_valid_user_json()` 返回固定英文 JSON 错误。
+- 会丢失现有多语言错误语义。
+
+### 不采纳 `9f8a68cd` 的 `AddResult.id`
+
+原因：
+- 本轮计划里明确要求 `svc_add` 返回 `entry_id`。
+- `d7720662` 的字段命名与 MCP 使用方式更贴近计划要求。
+
+---
+
+## 与原计划的覆盖情况
+
+两份实现都完成了大部分代码修改，但验证项整体没有补齐，当前更像“代码已改，测试仍不足”。
+
+### 已基本完成
+
+1. 导入/导出链路补 `secret_types`
+2. env map `.` -> `__`，并在冲突时返回错误
+3. API key `rows_affected()` 检查
+4. MCP `secrets_add` 避免提交后二次回查竞态
+5. MCP `secrets_find` 不再把 count 错误吞成 `0`
+6. MCP `secrets_rollback` 不再要求 encryption key
+7. Web JSON API 引入 `key_version` 严格校验
+8. Web PATCH 补长度校验
+
+### 尚需补齐的验证
+
+1. export/import round-trip 测试
+   - `password` / `key` / `text` 三种类型导出再导入后保持不变
+
+2. legacy import 测试
+   - 老格式缺失 `secret_types` 时默认回落到 `text`
+
+3. env map 测试
+   - `db.password` vs `db_password`
+   - 带 `prefix`
+   - 多 entry 合并冲突
+
+4. rollback 测试
+   - 恢复字段是否符合预期
+   - 并发更新 + 回滚不依赖过期值
+
+5. `regenerate_api_key` 测试
+   - 正常用户返回新 key
+   - 不存在用户返回错误
+
+6. MCP tool 测试
+   - `secrets_find` count 失败路径
+   - `secrets_rollback` 无 encryption key 也可执行
+
+7. Web session / validation 测试
+   - `key_version` mismatch -> `401`
+   - 用户不存在 / session 损坏 -> 正确错误
+   - `folder/type/name/notes` 超长 -> `400`
+
+---
+
+## 执行步骤
+
+1. 以 `d7720662` 对应实现为合并基线。
+2. 手动吸收 `9f8a68cd` 中 `web/entries.rs` 的常量化长度报错文案。
+3. 手动吸收 `9f8a68cd` 中 `env_map.rs` 的 `env_prefix_with_and_without_prefix` 测试。
+4. 不引入 `9f8a68cd` 的 `rollback.rs`、`web/mod.rs`、`AddResult.id` 方案。
+5. 针对原计划缺失的验证项补测试。
+6. 跑质量门禁：
+
+```bash
+cargo fmt -- --check
+cargo clippy --locked -- -D warnings
+cargo test --locked
+```
+
+7. 跑发布前检查：
+
+```bash
+./scripts/release-check.sh
+```
+
+8. 确认版本和 tag：
+   - `crates/secrets-mcp/Cargo.toml` 已 bump（合并执行时为 `0.5.21`，因 `crates/**` 有变更）
+   - `jj tag list`
+
+---
+
+## 备注
+
+如果后续要做最终合并，建议以 `d7720662` 为基础继续补测试，而不是尝试把两份实现整合成第三套逻辑。这样改动面最小，风险也最低。
