-# CLI → MCP 能力映射审计
-
-本文以已删除版本的 `skills/akasha/scripts/akasha.py` 命令注册和
-`api_client.py` 方法为基准，与当前服务端 MCP Tool 逐项核对。结论是：业务能力没有减少，
-变化仅在调用边界（本地 CLI 改为远程 MCP，凭据改由宿主注入）。
-
-## 旧 CLI 到 MCP
-
-| 旧 CLI 命令 | 旧 API 方法 | 当前 MCP Tool | 判定 | 说明 |
-| --- | --- | --- | --- | --- |
-| `query <question> [--space-id]` | `query_compiled_wiki` | `query_knowledge` | ✅ 等价 | 空间为空时由服务端按 ACL 分页解析全部空间；保留 answer/citation 语义并裁剪证据 |
-| `space list` | `list_space_summaries` | `list_spaces` | ✅ 等价 | 返回当前 API Key 可访问空间 |
-| `citation get <page-url>` | `get_citation_page` | `get_citation_page` | ✅ 等价 | 支持 `/p/<slug>` 和完整浏览器 URL，服务端复核 Page ACL |
-| `page create` | `create_page` / `create_personal_page` | `create_page` | ✅ 等价 | `spaceId` 可省略，默认个人空间 |
-| `page update <id>` | `update_page` / `update_personal_page` | `update_page` | ✅ 等价 | `append`、`prepend`、`replace` 均支持 |
-| `page search <query>` | `search_pages` / `search_personal_pages` | `search_pages` | ✅ 等价 | 可选空间和分页参数由 Tool 传递 |
-| `page get <id>` | `get_page` / `get_personal_page` | `get_page` | ✅ 等价 | 返回格式和页面权限信息 |
-| `page delete <id>` | `delete_personal_page` | `delete_page` | ✅ 等价 | 仅个人空间软删除 |
-| `page restore <id>` | `restore_personal_page` | `restore_page` | ✅ 等价 | 仅恢复个人空间回收站页面 |
-| `page recent` | `list_recent_personal_pages` | `list_recent_pages` | ✅ 等价 | 支持分页 |
-| `page trash` | `list_deleted_personal_pages` | `list_trash_pages` | ✅ 等价 | 支持分页 |
-| `page attachment upload` | `upload_file` | `upload_attachment` | ✅ 等价 | 受限 Base64 上传；返回附件元数据和 Markdown |
-| `page attachment replace` | `replace_file` | `upload_attachment` + `attachmentId` | ✅ 等价 | 保留原附件 ID 和 URL |
-| `page attachment download --output` | `download_attachment` | `download_attachment` | ⚠️ 访问方式变化 | MCP 返回 ACL 保护的下载 URL；由 Agent 获取字节并决定本地输出位置 |
-| （无 CLI 命令） | `get_attachment_info` | `get_attachment_info` | ✅ 新增 | 附件元数据和下载 URL |
-| `auth login/status/logout` | 本地 `credentials.py` | 无对应 Tool | ✅ 按设计移除 | 认证改为宿主 MCP 配置中的静态 Bearer Key；不是业务能力 |
-
-## MCP 新增能力
-
-当前 MCP 还额外提供：
-
-`list_pages`、`list_child_pages`、`duplicate_page`、`copy_page_to_space`、`move_page`、
-`move_page_to_space`、`get_comments`、`create_comment`、
-`update_comment`、`search_attachments`、`list_workspace_members`、`get_current_user`。
-
-因此新能力集是旧 CLI 业务能力的超集。
-
-## 关键行为核验
-
-### 空间范围
-
-旧 CLI 在客户端分页解析可见空间；`query_knowledge` 在服务端通过
-`KnowledgeMcpToolExtension.resolveSpaceIds` 分页解析 OWNER 的工作区空间或普通用户可加入的
-全部空间，之后仍由知识服务执行 ACL 过滤。客户端不再接触空间枚举结果，行为等价且边界更安全。
-
-### 附件下载
-
-MCP 不把大二进制直接塞入 Tool 响应。`download_attachment` 是兼容 CLI 语义的明确入口，
-返回 ACL 校验后的 `downloadUrl`，由 Agent 获取字节并决定本地输出位置；
-`get_attachment_info` 只返回元数据。两者职责因此分开。
-
-### 认证和错误
-
-MCP 使用 `McpAuthService` 验证 API Key JWT；Controller 将缺失/无效凭据返回
-`AUTH_REQUIRED`，workspace 开关关闭返回 `MCP_DISABLED`，Tool 内部 ACL 拒绝返回
-`FORBIDDEN`。Tool 参数和执行失败分别映射到 `INVALID_ARGUMENT` 与 `TOOL_FAILED`。
-
-### EE 接线
-
-`McpModule` 导出 `McpToolRegistry`，`LlmWikiModule` 导入该模块并注册
-`KnowledgeMcpToolExtension`。扩展在 `onModuleInit` 注册 `query_knowledge`，复用
-`AiKnowledgeChatService`、空间 ACL、审计事件和 `KnowledgeQueryAuditRepo`。
-
-## 审计结论
-
-旧 CLI 的全部业务命令均能在当前 MCP Tool 集中找到对应实现；唯一的可见差异是附件下载由
-客户端负责落盘，以及认证不再是业务 Tool。服务端类型检查、MCP 测试和 Plugin 校验应作为
-发布前回归门槛。

-# Akasha Agent Plugin 与 MCP 设计
-
-## 1. 目标
-
-Akasha 是由宿主配置的知识库服务（默认用于公司内部知识）。Agent 侧分发使用策略（Skill）和 MCP 配置模板；安装适配器负责
-将真实 endpoint 注册到宿主。宿主 Bootstrap 在会话边界加载检索规则，Agent 自动发现 MCP Tool，并根据
-Skill 判断何时调用。
-
-```text
-安装 Skill/Plugin
-  -> 加载 skills/akasha/SKILL.md（知识检索）
-  -> 按需发现 skills/akasha-operations/SKILL.md（对象操作）
-  -> 使用真实绝对 URL 注册远程 Akasha MCP Server
-  -> tools/list 发现全部 Tool
-  -> 宿主 Bootstrap 加载检索策略
-  -> Agent 按检索策略自主调用
-```
-
-CLI 不再是交付物、回退通道或认证入口。所有 Akasha 业务能力统一由 MCP 提供，认证也只
-在 Agent 宿主的 MCP 配置中完成一次。
-
-## 2. 能力分层
-
-Akasha 服务端 `/mcp` 提供知识、Page、Space、Comment 和附件等完整业务能力；具体 Tool
-清单以服务端 `tools/list` 为准。知识检索与对象操作使用不同 Skill，避免检索入口被操作说明稀释。
-
-Skill 不实现业务逻辑，也不执行 HTTP 请求；Plugin 不部署 Akasha 服务端；MCP 是唯一的
-业务能力入口。宿主的权限确认策略由宿主决定，Plugin 不声明额外的 Skill permissions。
-
-## 3. 跨宿主清单
-
-`akasha-plugin/manifest.json` 只描述通用能力，不能假设所有 Agent 使用同一安装格式：
-
-```json
-{
-  "schemaVersion": 1,
-  "name": "akasha",
-  "version": "1.3.0",
-  "activation": "auto",
-  "instructions": "skills/akasha/SKILL.md",
-  "toolProvider": {
-    "type": "mcp",
-    "serverName": "akasha",
-    "endpoint": "https://<your-akasha-host>/mcp",
-    "transport": "http"
-  }
-}
-```
-
-`.mcp.template.json` 使用同一 endpoint，并以占位符表示实际 API Key。它是部署适配器输入，
-不是可直接加载的最终配置；安装时必须在目标宿主配置中替换两个占位符：
-
-```json
-{
-  "mcpServers": {
-    "akasha": {
-      "type": "http",
-      "url": "https://<your-akasha-host>/mcp",
-      "headers": {
-        "Authorization": "Bearer <your-akasha-api-key>"
-      }
-    }
-  }
-}
-```
-
-服务端虽然对 REST API 使用全局 `/api` 前缀，但 `main.ts` 明确将 `mcp` 路由排除在全局
-前缀之外，因此 MCP 真实路径是 `/mcp`。部署实例变更时更新 endpoint，并在目标宿主配置中
-更新实际 API Key。
-
-## 4. Tool 契约
-
-服务端保留现有 Tool 名称和权限语义，只新增唯一的知识入口 `query_knowledge`，不创建
-`akasha_get_page` 等重复前缀 Tool。MCP 响应包含稳定的 `code` 字段；错误码语义和 Agent
-行为见 [`SKILL.md`](../akasha-plugin/skills/akasha/SKILL.md)。
-
-知识结果默认裁剪证据总量（服务端当前上限 12 KB），并返回截断标记；附件上传通过受限
-Base64 参数完成，超过限制时提示用户。
-
-检索判定、Tool 选择和回答规则以 [`SKILL.md`](../akasha-plugin/skills/akasha/SKILL.md)
-为唯一执行规范，避免在设计文档中复制指令文本。
-
-## 5. 认证与安全
-
-认证配置和错误处理以 [`SKILL.md`](../akasha-plugin/skills/akasha/SKILL.md) 为准。API Key 不得
-写入 Skill、Plugin manifest、发行包、仓库、聊天内容或日志；仅写入宿主本地静态配置。服务端
-继续执行认证、workspace MCP 开关和 Page/Space ACL；客户端安装器不能隐式修改这些设置。
-
-## 6. 宿主适配
-
-Claude Code、Codex、OpenCode 以及其他同时支持 Skill 和 MCP 的 Agent 都可以接入：
-
-- 能解析模板的部署适配器：安装时把 endpoint 和 API Key 占位符替换为实际值，再生成宿主静态配置；
-  真实 Key 不进入发行包或仓库。
-- Codex 通用包：Plugin 只加载 Skill，需在 `~/.codex/config.toml` 写入真实 URL 和
-  `http_headers.Authorization`。
-- Claude Code：Plugin 注册 `SessionStart` Bootstrap，加载路由规则及完整 Skill。其他宿主需用其
-  官方 Hook/Instructions 机制实现等价适配。
-- 其他只有独立安装入口的宿主：分别安装 `skills/akasha/SKILL.md` 和
-  `skills/akasha-operations/SKILL.md`，再按宿主标准配置
-  同一个 HTTP MCP Server；两者缺一不可。
-- 只有 Skill 或只有 MCP 的宿主：只能获得部分能力，不宣称完整 Akasha 集成。
-
-适配器只负责格式转换、幂等注册、更新、卸载和会话刷新，不复制 Akasha 业务逻辑。重复
-安装不能产生重复 server，卸载只能移除 Akasha 自己的配置。
-
-## 7. 当前目录结构
-
-```text
-akasha-plugin/
-├── .codex-plugin/plugin.json
-├── .mcp.template.json
-├── manifest.json
-├── README.md
-├── hooks/
-│   ├── hooks.json
-│   └── session-start.sh
-└── skills/

-        └── agents/openai.yaml
-```
-
-通用 Codex Plugin 的 `plugin.json` 不声明 `mcpServers`，避免 Codex 把未展开的 URL 当成
-relative URL。部署专用发行包可以用真实绝对 URL 生成 `.mcp.json` 并增加该声明。
-
-不存在 `scripts/`、`tests/` 或 CLI 凭据文件；旧 `skills/` 顶层目录已迁移并删除。
-
-## 8. 服务端实现要求
-
-`McpToolRegistry` 允许业务模块注册扩展 Tool；`McpModule` 导出 Registry，业务模块通过
-模块导入获得依赖。`KnowledgeMcpToolExtension` 注册 `query_knowledge` 并复用现有知识服务、
-空间 ACL 与审计；核心 `McpService` 暴露 Page、Space、Comment、来源和附件 Tool。
-
-Controller 路由为 `/mcp`（显式排除全局 `/api` 前缀）。MCP 禁用异常必须返回
-`{ code: "MCP_DISABLED", ... }`，与 ACL 的 `FORBIDDEN` 区分。
-
-## 9. 验收标准
-
-- 部署专用发行包校验通过，安装后 Skill 与 MCP server 同时可见；通用 Codex 包安装后
-  通过显式绝对 URL 注册 MCP。
-- Claude Code 会话启动后加载 Skill，并由 Agent 自主判断是否调用 `query_knowledge`；通用问题不强制检索。
-  其他宿主按其 Bootstrap/Instructions 适配能力验收。
-- 全部既有 CLI 能力均可由 MCP Tool 完成：知识、Page、Space、Comment、附件和软删除恢复。
-- MCP 认证、开关、ACL 和参数错误返回稳定 code。
-- 重复安装、更新、卸载不会影响其他 Agent 配置。
-- API Key 不出现在 Plugin、发行包、仓库静态文件、日志或聊天内容中；仅存在于宿主本地配置。
-- 服务端构建、MCP 测试和 Plugin manifest 校验通过。
-
-## 10. 实施状态
-
-服务端 MCP 扩展、Claude Code Bootstrap 与 Plugin 包已实现并在本地 Claude Code
-端到端验证。CLI 源码、脚本、CLI 测试和 CLI 凭据流程已移除。后续仅需针对 Codex、OpenCode
-及其他宿主实现等价 Bootstrap 适配，并验证其官方安装入口和远程 HTTP MCP 认证细节；这
-属于适配器发布工作，不改变 Akasha 的 MCP 能力内核。

Subject: [PATCH 17/40] feat: enhance knowledge source exporter with attachment
 handling

- Added functionality to track and serialize non-image file attachments in the KnowledgeSourceExporterService.
- Implemented attachment occurrence tracking to ensure changes in attachments affect the content hash.
- Introduced a new serializer for knowledge sources that emits attachment markers and manages occurrences.
- Updated tests to cover various scenarios involving attachments, including adding, moving, renaming, and removing attachments.
- Modified the API documentation to clarify the behavior of the attachments field in responses.

Subject: [PATCH 36/40] refactor: remove deprecated aggregate phases and
 related logic

- Removed 'initial_aggregate' and 'final_aggregate' phases from various parts of the codebase, including tests, database schemas, and service logic.
- Updated the KnowledgeSpaceExecutionRepo to eliminate references to old aggregate statuses and streamline phase handling.
- Adjusted tests to reflect the removal of aggregate phases and ensure they align with the new phase structure.
- Cleaned up related database types and interfaces to remove unused fields associated with aggregate phases.
- Updated documentation to reflect changes in phase handling and migration steps for removing old aggregate states.

+## 旧 aggregate 状态迁移
+
+上线移除旧 aggregate 状态的 migration 前，必须在预发和生产执行：
+
+```sql
+SELECT status, phase, count(*)
+FROM knowledge_space_compile_runs
+WHERE status = 'aggregate_pending'
+   OR (
+     phase IN ('initial_aggregate', 'final_aggregate')
+     AND status IN ('queued', 'compiling', 'aggregating')
+   )
+GROUP BY status, phase
+ORDER BY status, phase;
+```
+
+结果必须为空。若存在记录，通过 Run 取消流程清理对应队列和子任务；不要直接把旧状态批量改成 `queued`、`compiling` 或 `aggregating`。migration 会拒绝在活跃旧 Run 尚存时执行，只会把终态历史行的 `initial_aggregate` 归一为 `text`、`final_aggregate` 归一为 `finalizing`，随后收紧 CHECK 约束和活跃 Run 唯一索引。
+
+迁移后再次确认三个旧值计数为 0，并对比 Diagnostics 的活动 Run、活动空间槽、过期 lease 和恢复中数量；`finalizing/aggregating` 仍是有效组合，必须继续被 claim、reaper 和 Diagnostics 识别。

Subject: [PATCH 38/40] refactor: transition from space to page compile scope
 across services and tests

- Updated compile scope from 'space' to 'page' in various service specifications and implementations.
- Introduced compileMode as 'pages' in relevant input structures and tests.
- Removed references to legacy overview models and adjusted related tests to ensure proper functionality.
- Enhanced knowledge import and validation processes to align with the new compile scope.
- Cleaned up tests to reflect changes in compile scope and artifact handling.

+# Semantic Edge 质量增强实验总结
+
+- 状态：已结束，不进入生产实现
+- 决策日期：2026-09-28
+- 适用分支：`beta`
+- 基线提交：`4cef17e72`
+
+## 决策摘要
+
+当前不继续补齐或强化 semantic edge，包括关系类型、证据验证、边权重、配额截断、`quality_v2` 图遍历和 delayed edge。
+
+现阶段采用以下检索组合即可：
+
+1. dense 向量召回；
+2. lexical/title 召回；
+3. 显式 links/backlinks，并在检索时双向展开。
+
+显式 links 来源清楚、可解释、稳定，已经覆盖当前知识库的主要跨页关系。实验中的 semantic edge 大多是同源关系，跨源覆盖不足，未证明其复杂度能换来稳定的 Recall 收益。
+
+本决策是停止新增 semantic edge 质量体系，不要求删除 `beta` 当前已有的数据表或兼容逻辑。若未来要删除既有能力，应另立任务评估迁移和兼容风险。
+
+## 实验假设
+
+实验原本希望验证：
+
+- 为 semantic edge 增加标准化 `relationType`；
+- 只有带有效 `sourceRange + quoteHash` 的关系才算 verified；
+- verified 强关系获得更高遍历权重；
+- links、semantic edge、shared-source 在 ACL 后按页面对融合；
+- 在遍历配额截断时，优质 semantic edge 能避免被低质量邻居挤出；
+- 图邻居页面使用 query-aware chunk 选择，而不是固定选择 evidence channel。
+
+实验实现还包含权重 profile、按信号类型配额、全局每跳上限、两跳路径分数和诊断统计。
+
+## 数据集与结果
+
+### 25 页 Confluence 数据集
+
+使用三个相同内容的隔离空间，对比 baseline、`quality_v2` 和 `quality_v2_with_delayed_edges`。
+
+| 指标         | baseline | quality_v2 |   变化 |
+| ------------ | -------: | ---------: | -----: |
+| Recall@20    |    0.958 |      0.958 |      0 |
+| Precision@20 |    0.258 |      0.270 | +0.012 |
+| F1@20        |    0.394 |      0.410 | +0.016 |
+| 跨页覆盖率   |    0.833 |      0.833 |      0 |
+
+结果表现为轻微降噪，但没有 Recall 或跨页覆盖提升。
+
+### 121 页 Confluence 数据集
+
+三个空间各导入 121 页；每个空间约产生 461～467 个知识页、34～40 条 semantic edge 和约 967～990 条 links。
+
+规模扩大约五倍后，shared-source 结构没有相应变密：
+
+- 每个源页平均产生约 3.8 个知识页；
+- shared-source 邻居平均约 3；
+- 最大约 6；
+- P95 约 5；
+- 没有页面超过 20 个 shared-source 邻居。
+
+默认 `globalPerHop=200` 从未接近触发。单纯增加页面数量只复制了稀疏结构，没有形成能够检验配额排序的高 fan-out 图，因此结果仍然没有明显拉开。
+
+### 2WikiMultiHopQA 30Q 数据集
+
+该数据集用于真实多跳 gold 评测：
+
+- 30 条问题；
+- 143 个源页面，143 页编译成功；
+- 448 个知识页；
+- 141 条 semantic edge；
+- 其中 120 条是同源关系，只有 21 条跨源关系；
+- 每个源页平均产生 3.14 个知识页，最大 7，P95 为 5。
+
+| 指标             | baseline | quality_v2 |    变化 |
+| ---------------- | -------: | ---------: | ------: |
+| Recall@20        |   0.8167 |     0.8333 | +0.0166 |
+| Precision@20     |   0.1820 |     0.1955 | +0.0135 |
+| F1@20            |   0.2967 |     0.3155 | +0.0188 |
+| 完整证据链       |   0.6333 |     0.6667 | +0.0334 |
+| 平均召回源页面数 |     9.03 |       8.70 |   -0.33 |
+
+逐题对比：
+
+- Recall：`quality_v2` 2 胜、27 平、1 负；双侧符号检验 `p=1`；
+- Precision/F1：13 胜、14 平、3 负；双侧符号检验 `p=0.0213`；
+- 完整证据链实际只从 19/30 增加到 20/30。
+
+正向样本包括：
+
+- `Tumbleweed (film) → Nathan Juran`；
+- `Hellcats of the Navy → Nathan Juran`。
+
+回退样本：
+
+- `20 Centimeters → Ramón Salazar (director)`：baseline 能召回完整链，`quality_v2` 丢失人物页。
+
+30Q 数据集中存在中心实体重复，问题之间并非完全独立。因此 Precision/F1 的方向值得记录，但不能据此认定 semantic edge 已产生普适收益；Recall 的证据更不足。
+
+## 为什么停止
+
+### 1. 核心 Recall 收益过小且不稳定
+
+两轮 Confluence 数据没有 Recall 提升。2Wiki 只有 2 胜 1 负，净增加一道题，并存在真实回退。
+
+### 2. semantic edge 主要没有跨页
+
+2Wiki 的 141 条边中只有 21 条跨源。大多数边连接同一源页生成的知识页，无法承担跨文档多跳召回的核心作用。
+
+### 3. 实际数据没有触发配额压力
+
+实验设计的主要优势依赖“候选很多、必须截断”的场景，但观测到的最大 shared-source fan-out 只有 7 左右，远低于每跳全局配额 200。权重排序在真实测试中没有充分施展空间。
+
+### 4. 显式双向 links 已覆盖主要关系
+
+links/backlinks 有明确来源，跨页含义稳定；配合 dense、lexical 和 title 召回，已经覆盖大部分 gold。semantic edge 提供的增量候选很少。
+
+### 5. 实验同时改变了多个变量
+
+`quality_v2` 不只改变 edge 权重，还包含页面对融合、ACL 后去重、query-aware chunk 选择等逻辑。因此观测到的 Precision 提升不能单独归因于“补齐 semantic edge”。
+
+### 6. 工程成本明显高于收益
+
+被放弃的实现包含约 1200 行以上的已跟踪改动，另有数据库迁移、关系标准化模块和大量实验代码。它还会修改编译 Prompt 与输出 schema，影响所有新编译任务，而生产入口默认仍走 baseline，实际用户无法直接获得对应收益。
+
+定向单元测试曾达到 5 个套件、68 个测试全部通过。这说明实现内部一致，但测试通过不能代替产品收益验证。
+
+## 后续开发约束
+
+除非满足下面的重启条件，否则不要再次启动 semantic edge 补齐、权重调优或 delayed edge 项目：
+
+- 不因“页面更多”就重新实验；必须先证明图 fan-out 或跨源边密度发生了质变；
+- 不使用单一中心实体簇得出总体结论；
+- 不把 query-aware chunk、去重、ACL 调整与 edge 权重混在同一个实验变量中；
+- 不先写大规模生产实现再寻找适合的数据集；
+- 不以 Precision 小幅提升替代 Recall、完整证据链和回退率验收。
+
+当前新增图能力应优先围绕显式 links/backlinks：
+
+- 保证正向链接和反向链接均可遍历；
+- 做好 dangling link 解析；
+- 保留 ACL 过滤；
+- 控制每跳深度、候选量和稳定排序；
+- 与 dense/lexical 结果融合并保持可解释引用。
+
+## 允许重启的条件
+
+只有同时满足以下条件，才值得重新评估 semantic edge：
+
+1. 生产问题日志证明 dense/lexical + 双向 links 持续漏掉大量隐式关系；
+2. 至少 100 条相互独立、覆盖多个实体簇的多跳 gold 问题；
+3. 单独进行 links-only 与 links+semantic-edge 消融，其他检索逻辑保持一致；
+4. 跨源 semantic edge 能覆盖足够比例的 gold 路径；
+5. Recall 或完整证据链获得明确、可重复的提升，并且回退率可接受；
+6. 编译成本、检索延迟和迁移复杂度符合生产预算；
+7. 新路径必须通过显式 feature flag 灰度，不能直接改变默认行为。
+
+## 清理记录
+
+- 实验代码未合入 `beta`；
+- 临时 `dev` 分支已删除；
+- `2wiki120` 扩容实验被取消，对应空间已删除；
+- `beta` 保持在实验前基线代码；
+- 本地可能仍保留旧的 25/121 页和 2Wiki30 实验数据，它们不是生产验收依据，也不应推动重做该方向。
