+## §26. Gitea 协作规范设计
+
+> **状态**: ✅ 已实现（PR #69）
+> **日期**: 2026-06-14
+
+### 26.1 设计目标
+
+团队三个仓库（moziplus_v2 / quant_live / vnpy）在 Gitea 上独立存在，协作时存在三个问题：
+
+1. **标题不可辨识**：`Fix mail API` 看不出是哪个项目、什么类型的改动
+2. **Label 缺失**：无统一标签体系，无法按类型/优先级筛选
+3. **填写无约束**：Issue/PR 内容格式随意，审查时缺少关键信息
+
+本规范的目标：让人类一眼识别项目+类型，让 Agent 可程序化遵循，让模板降低填写门槛。
+
+### 26.2 规范设计
+
+#### 26.2.1 标题规范
+
+**规则**：所有 Issue/PR 标题必须包含项目代号前缀。
+
+| 类型 | 格式 | 示例 |
+|------|------|------|
+| Issue | `[代号] type: 简述` | `[moz] bug: Mail API 500 when comment_type invalid` |
+| PR | `[代号] type(scope): 简述` | `[moz] impl(daemon): WikiGuideSection 注入` |
+
+**项目代号**：moz=moziplus_v2, quant=quant_live, vnpy=vnpy
+
+**type 清单**：bug / feat / impl / fix / docs / test / ci / refactor / chore
+
+**设计决策**：
+- 为什么用代号前缀而不是靠仓库隔离？— 团队成员同时在多仓库协作，通知列表（Mail、Gitea dashboard）混合展示时代号前缀提供即时辨识。仓库隔离解决不了跨仓库视图的辨识问题
+- PR 加 `scope` 是因为 PR 通常涉及具体模块（daemon / api / frontend），Issue 不需要
+
+#### 26.2.2 Label 体系
+
+采用 `type/*` + `priority/*` 双命名空间，替代旧标签（bug/feature/improvement/security）：
+
+| 标签 | 色值 | 说明 |
+|------|------|------|
+| `type/bug` | #ee0701 | Bug 修复 |
+| `type/feat` | #84b6eb | 新功能 |
+| `type/impl` | #c5def5 | 按设计实现 |
+| `type/docs` | #fbca04 | 文档 |
+| `type/test` | #0e8a16 | 测试 |
+| `type/ci` | #d4c5f9 | CI/CD |
+| `type/refactor` | #ff6f00 | 重构 |
+| `priority/P0` | #b60205 | 紧急 |
+| `priority/P1` | #d93f0b | 高 |
+| `priority/P2` | #fbca04 | 中 |
+| `priority/P3` | #cfd3d7 | 低 |
+
+**设计决策**：
+- 用 `type/` `priority/` 命名空间而非扁平命名，避免标签膨胀时冲突，且在 Gitea UI 中按前缀分组显示
+- type 用暖色系（红/橙/黄），priority 用冷→热渐变（灰→蓝→黄→红），视觉上两类标签不混淆
+- ⚠️ 已知问题：`type/impl`(#c5def5) 与 `priority/P3` 色值相近。P3 已调整为灰色 #cfd3d7 以区分
+
+#### 26.2.3 Issue/PR 模板
+
+**Issue 模板**（3 种）：bug.yml / feature.yml / test.yml
+
+覆盖决策：只做最高频的 3 种类型（bug 报告、功能需求、测试任务），其余类型（docs/ci/refactor）频率低，走自由创建。每种模板包含描述、复现/方案、优先级字段。
+
+**PR 模板**（1 种）：PULL_REQUEST_TEMPLATE.md
+
+改动类型 checklist + 检查清单（标题格式、开发→安装目录同步、测试、设计文档更新）。
+
+### 26.3 执行机制
+
+规范通过四层路径保证执行，每层职责不同：
+
+| 层 | 载体 | 职责 | Token 成本 |
+|----|------|------|-----------|
+| **L1** | TOOLS.md（Agent workspace） | 代号表 + 格式速查，Agent 静态可见 | ~100 |
+| **L2** | `GiteaConventionSection`（priority=55） | 每次 spawn 动态注入，提醒标题格式 | ~80 |
+| **L3** | `gitea-conventions` Skill（extraDirs） | 完整规范（标题/分支/commit/label），Agent 按需加载 | 按需 |
+| **Gitea** | Issue/PR Template + Label（仓库级） | 人类创建时表单引导，标签选择 | — |
+
+**L2 设计决策**：
+- `GiteaConventionSection` priority=55，排在 Constraints(50) 之后、Extension(60) 之前。标题规范属于约束类，但优先级低于安全/流程约束
+- 注入所有 handler（Task/Toolchain/Mail），因为任何 handler 都可能创建 Issue/PR
+- ⚠️ L1 文件在各 Agent workspace（`~/.openclaw/workspace-*/TOOLS.md`），不在仓库管理。Agent workspace 变更不通过 PR
+
+### 26.4 Label 迁移策略
+
+旧标签（bug/feature/improvement/security/risk:high/priority:high）已由新体系替代：
+
+- **旧标签保留不动**（不删除），避免历史 Issue 丢失标签信息
+- **新 Issue/PR 使用新标签**（type/* + priority/*）
+- 当前不做批量迁移。如有需要可后续通过 Gitea API 批量替换
+
+### 26.5 与其他章节的关系

+## §14. Mail 失败通知机制
+
+### 20.1 背景
+
+Mail 是 A→B 点对点通信，失败应通知发件人 A，而非统一 @pangtong。
+
+当前机制（v1.3 已实现）：
+- `_mark_task("failed")` 对 _mail 项目：调用 `mail_notify.notify_mail_failed` 通知发件人
+- `_mark_task("failed")` 对 Task 项目：@pangtong-fujunshi（F2 原逻辑不变）
+- `_mail_auto_complete` 的 no_reply_found：标 failed 后通知发件人
+- 防递归：`must_haves.system_notify=true` 的邮件失败不再递归通知
+
+### 20.2 失败场景与重试机制
+
+所有可能的失败路径及其重试/等待机制（重试上限 max_retries=3，agent_timeout=630s）：
+
+| 失败类型 | 机制 | 重试次数 | 每次耗时 | cooldown | 最长总耗时 |
+|---|---|---|---|---|---|
+| `gateway_timeout` | 续杯 | 3 | 630s | 无 | ~31.5 分钟 |
+| `crashed` | ticker 兜底 | 3 | ~2-5 分钟 | 60s + 30s ticker | ~15 分钟 |
+| `api_error`（rate_limit） | 推 pending（**待改为续杯**） | 3 | ~2.5 分钟 | 120s | ~8 分钟 |
+| `compact_interrupted` | 续杯 | 3 | 630s | 60s | ~34 分钟 |
+| `gateway_unreachable` | 续杯 | 3 | 630s | 60s | ~34 分钟 |
+| `lock_conflict` | 续杯 | 3 | 630s | 60s | ~34 分钟 |
+| `fallback_timeout` | 续杯(A3b) | 3 | 630s | 60s | ~34 分钟 |
+| `compact_wait` | monitor 等待 | 3 | 630s | 无 | ~31.5 分钟 |
+| `compact_hanging` | monitor → release | 3 | 630s | 300s | ~31.5 分钟 + ticker |
+| `max_monitor_timeouts` | monitor 上限 | 3 | 630s | 无 | ~31.5 分钟 |
+| `session_stuck` | revive 1 次 | 1 | ~30s | 无 | ~30 秒 |
+| `compact_failed` | 无重试 | 0 | — | 300s | 立刻 failed |
+| `auth_failed` | 无重试 | 0 | — | — | 立刻 failed |
+| `agent_error` | 无重试 | 0 | — | 300s | 立刻 failed |
+| `no_reply_found` | 无重试 | 0 | — | — | 立刻 failed |
+
+### 20.3 触发点
+
+| 触发点 | 文件 | 说明 |
+|---|---|---|
+| `_mark_task(failed)` | spawner.py | _mail 项目 → notify_mail_failed；Task 项目 → @pangtong |
+| `_mail_auto_complete` no_reply_found | dispatcher.py | Agent 正常退出但没回复 request → 标 failed → 通知发件人 |
+
+### 20.4 实现位置
+
+- `src/daemon/mail_notify.py`：`notify_mail_failed` + `_is_mail_project` + 通知模板
+- `src/daemon/spawner.py`：`_mark_task` 中 _mail/Task 分流
+- `src/daemon/dispatcher.py`：`_mail_auto_complete` 中 no_reply_found 后调 notify
+
+### 20.5 通知设计（v2.0 — AI Native）
+
+通知提供充足事实信息，不做硬编码处理建议。收件 AI 自行判断下一步。
+
+**通知结构**：
+```
+邮件投递失败通知
+
+📧 原始邮件：「{title}」
+👤 收件人：{to_agent}
+❌ 失败原因：{reason_human_readable}（{reason_raw}）
+📊 重试情况：{attempt_info}
+📋 上下文信息：
+{detail_formatted}
+
+常见失败原因参考：
+• no_reply_found：收件人未回复（Agent 未能识别或处理此邮件）
+• crashed / max_crash_count：收件人处理时进程崩溃（已自动重试 3 次）
+• max_retries：续杯耗尽（已自动重试 3 次，共约 34 分钟）
+• max_api_retry_count：API 连续失败达上限（rate_limit/500/503）
+• max_monitor_timeouts：处理超时达上限（共约 31.5 分钟）
+• gateway_timeout：Agent 执行超时（已续杯重试）
+• session_stuck：Agent 会话假死（lock PID 死亡，revive 失败）
+• revive_failed：会话假死后恢复失败
+• auth_failed：Agent 认证失败（配置问题）
+• fallback_exhausted：主模型和备用模型均失败
+• agent_failed：收件人主动标记失败
+• compact_failed：上下文压缩失败
+• compact_hanging：上下文压缩长时间未完成（等待超 31.5 分钟）
+• compact_interrupted：上下文压缩被中断（已自动重试 3 次）
+• gateway_unreachable：Gateway 不可达（已自动重试 3 次）
+• lock_conflict：会话锁冲突（已自动重试 3 次）
+• 其他：建议排查系统日志
+
+——系统自动通知
+```
+
+**reason 人话翻译映射**：
+
+| reason_raw | reason_human_readable | detail 提取 |
+|---|---|---|
+| `no_reply_found` | 收件人未回复 | 无额外信息 |
+| `crashed` | 处理时进程崩溃 | stderr_preview 前 200 字 |
+| `max_crash_count` | 连续崩溃达上限 | count + stderr_preview |
+| `max_retries` | 续杯耗尽 | count + retry_field |
+| `max_api_retry_count` | API 连续失败达上限 | count |
+| `max_monitor_timeouts` | 处理超时达上限 | count + elapsed_seconds |
+| `gateway_timeout` | Agent 执行超时 | retry_count |
+| `session_stuck` | 会话假死 | stuck_count |
+| `revive_failed` | 假死后恢复失败 | stuck_count |
+| `auth_failed` | 认证失败 | stderr_preview |
+| `fallback_exhausted` | 模型全部失败 | fallback_count + fallback_reason |
+| `agent_failed` | 收件人主动标失败 | 无 |
+| `compact_failed` | 上下文压缩失败 | stderr_preview |
+| `compact_hanging` | 压缩长时间未完成 | compact_wait_count |
+| `compact_interrupted` | 压缩被中断 | 无 |
+| `gateway_unreachable` | Gateway 不可达 | stderr_preview |
+| `lock_conflict` | 会话锁冲突 | 无 |
+| 默认 | 未知原因 | reason + stderr_preview（如有） |
+
+**重试情况格式**：
+- 有重试：`"已自动重试 {count} 次，共耗时约 {total_time}"`
+- 无重试：`"无法重试（{reason_human_readable}）"`
+
+### 20.6 防递归
+
+系统通知邮件（from=system）本身也可能失败：
+- 检查 `must_haves.system_notify=true` → 跳过递归通知
+- system 不是有效 Agent → 通知路由到 pangtong-fujunshi 代处理
+
+### 20.7 待实现改动
+
+#### P1：api_error rate_limit 改为可恢复 retry
+
+**当前**：`_classify_outcome` 中 rate_limit/500/503 → `api_error`，`should_retry=False`，走推 pending 路径。
+**改为**：`should_retry=True`，走续杯路径。cooldown 60s。上限仍 3 次。
+**改动文件**：`src/daemon/spawner.py` `_classify_outcome` 的 `api_error` 分支。
+**影响**：`api_retry_count` 机制可以废弃（统一用 `retry_count`），但保持向后兼容暂不删除。
+
+#### P2：通知模板更新（v2.0）
+
+**当前**：`mail_notify.py` 的 `_NOTIFY_TEMPLATE` 是静态模板，不传 detail。
+**改为**：动态模板，根据 reason 选择人话翻译 + 提取 detail 信息 + 格式化重试情况。
+**改动文件**：`src/daemon/mail_notify.py`。
+**新增**：`_REASON_MAP` 字典（reason → 人话 + detail 提取函数）。
+
+### 20.8 不改的
+
+| 项目 | 原因 |
+|---|---|
+| F2 @pangtong 对 Task 的逻辑 | Task failed 仍 @pangtong，只对 Mail 不同 |
+| no_reply_found 的判定逻辑 | 只在判定后加通知，不改判定本身 |
+| inform 类型邮件的完成逻辑 | inform 直接 done，不存在 no_reply_found |
+| 外部 API 的 from 校验 | system 不走 HTTP，外部无法伪造 |

+
+> 状态：v2 设计中
+> 作者：庞统
+> 日期：2026-06-13（v1），2026-06-14（v2 对齐 #11 四层架构）
+> 评审：待司马懿评审
+
+## 一、问题
+
+### 1.1 现状
+
+Agent（庞统、司马懿、张飞等）在执行任务时，不主动查询已有知识库（wiki-vault）。导致：
+
+1. **重复调研**：赵云查过的数据清洗经验，张飞又从头调研一遍
+2. **重复踩坑**：wiki-vault 里已有"vnpy load_bar 需要显式指定 end=None"的实践，张飞还是踩了
+3. **方案质量低**：做方案时纯靠推理，不查已有的优秀实践
+4. **知识 gap 无人管**：查不到相关知识时没记录，下次还是查不到
+
+### 1.2 根因
+
+不是没有知识库（wiki-vault 有 50+ practices 页面），也不是没有检索能力（wiki-query Skill 已存在）。
+
+**根因是注入时机**：Agent 不知道什么时候该查、没有强制机制让 Agent 在关键决策点查。
+
+### 1.3 目标
+
+1. Agent 在关键决策点**主动查询** wiki-vault
+2. 查不到相关知识时**自动记录** knowledge gap
+3. 定时任务处理 gap + 总结经验，**持续丰富** wiki-vault
+4. 不增加 prompt token 负担（不自动注入知识全文，只引导查询）
+
+## 二、调研
+
+### 2.1 Superpowers：强制 Skill 检查（最有效）
+
+**核心设计**：session-start hook 注入铁律级指令——
+
+> "If you think there is even a **1% chance** a skill might apply, you **ABSOLUTELY MUST** invoke the skill. This is not negotiable."
+
+配合 **Red Flags 表**防止 Agent 自合理化跳过：
+
+| Agent 的想法 | Red Flag 驳回 |
+|---|---|
+| "这个问题很简单" | 简单问题也需要查实践 |
+| "我需要更多上下文" | Skill 检查在澄清问题之前 |
+| "先看看代码" | Skill 告诉你怎么看代码 |
+| "我记住了这个 Skill" | Skill 会更新，重新读 |
+
+**为什么有效**：不靠 Agent "想起来"，靠铁律强制。Skill 触发在任何响应之前。
+
+### 2.2 Hermes：经验闭环 + Session Search
+
+**经验闭环**：完成复杂任务（5+ tool calls）→ 自动创建 Skill → 下次自然触发。
+
+**Session Search**：系统提示注入——"当用户提及过去内容时，主动搜索而非要求用户重复"。
+
+**为什么有效**：不是"知识查询"而是"行为内化"——经验变成 Skill，Skill 有 description 触发词。
+
+### 2.3 结论
+
+综合两个项目的优势：
+
+| 设计点 | 来源 | 我们的做法 |
+|--------|------|-----------|
+| 铁律级强制 | Superpowers | L0 Hook 注入 + L1 SOUL.md 行为引导 |
+| Red Flags 反合理化 | Superpowers | 知识查询 Red Flags 表（L1 SOUL.md） |
+| 经验内化 | Hermes | 经验→wiki-vault→下次查询 |
+| 渐进式披露 | Hermes | 先查 summary，按需读全文 |
+
+## 三、设计决策（对齐 #11 四层架构）
+
+> **层级体系严格对齐 [#11](./11-context-layers-redesign.md)**，不自创命名。
+
+### 总览
+
+| #11 层级 | 知识注入角色 | 本设计覆盖 | 注入方式 |
+|----------|------------|-----------|---------|
+| **L0 铁律层** | "做方案前先查 wiki-vault" | ✅ D16-1 | Hook 每轮强制注入 |
+| **L1 角色层** | TOOLS.md 知识库速查表 + SOUL.md Red Flags | ✅ D16-2 | Workspace 文件自动注入 |
+| **L2 引擎注入层** | 三种 handler 各注入 WikiGuideSection | ✅ D16-3 | PromptComposer 拼装 |
+| **L3 被动参考层** | wiki-query Skill 按需触发 | ✅ D16-4 | extraDirs Description 匹配 |
+| 运维层 | gap 闭环 cron job | ✅ D16-5 | 不属于上下文分层 |
+
+### D16-1：L0 铁律层 — 新增一条 wiki 查询铁律
+
+L0 只放跨系统通用的、不可绕过的行为底线。wiki 查询铁律和 GATE 门控同级。
+
+**新增铁律**：
+
+```
+<wiki-rule>
+做方案前先查 wiki-vault，有 1% 相关就要查。查不到记 knowledge-gaps.md。
+</wiki-rule>
+```
+
+**注入方式**：和 `<gate-rules>` / `<delegation-rule>` 并列，Hook 每轮强制注入。
+
+**覆盖范围**：所有 Agent、所有场景（不限于 moziplus spawn 的子任务）。
+
+### D16-2：L1 角色层 — TOOLS.md + SOUL.md
+
+#### TOOLS.md（✅ 已完成）
+
+各 Agent workspace 的 TOOLS.md 中已有「LLM Wiki 知识库」段，包含：
+
+- 速查表（场景 → 怎么做 → 什么时候用）
+- 检索原则（index.md → summary → grep → 整页读取，从便宜到昂贵）
+- 目录结构（wiki-vault / practices / concepts / skills / ...）
+- 铁律（做方案前先查、查不到记 gap）
+
+#### SOUL.md Red Flags
+
+在各 Agent 的 SOUL.md 中加入知识查询 Red Flags 表（和 Superpowers 一致）：
+
+| Agent 的想法 | 反驳 |
+|---|---|
+| "这个我以前做过" | 知识库可能已更新，查一下确认 |
+| "先做再说" | 做方案前查实践比做错了返工便宜 |
+| "这个领域我熟悉" | 熟悉≠知道最新实践，wiki-vault 持续更新 |
+| "查知识库浪费时间" | 重复踩坑浪费的时间远大于查询时间 |
+
+### D16-3：L2 引擎注入层 — 三种 handler 各注入 WikiGuideSection
+
+L2 是 BootstrapBuilder/PromptComposer 动态拼装的 prompt 段。当前有三种 handler，各有自己的 PromptSection 实现：
+
+#### 当前 handler 结构
+
+| Handler | Sections（priority） | 有 wiki 引导？ |
+|---------|---------------------|--------------|
+| **TaskHandler** | Context(10) → Prior(20) → RoleSkill(30) → API(40) → Constraints(50) | ❌ |
+| **MailHandler** | Context(10) → API(40) → Constraints(50) | ❌ |
+| **ToolchainHandler** | Context(10) → API(40) → Constraints(50) | ❌ |
+
+#### 新增 WikiGuideSection（priority=60，PRIORITY_EXTENSION）
+
+创建一个**通用 PromptSection**，三种 handler 的 `get_sections()` 都注入：
+
+```python
+# 可放在 prompt_composer.py 或独立文件，三种 handler 共用
+
+class WikiGuideSection:
+    """知识查询引导段 — 引导 Agent 在关键决策点查 wiki-vault。"""
+
+    name: str = "wiki_guide"
+    priority: int = 60  # PRIORITY_EXTENSION
+
+    WIKI_GUIDE = (
+        "## 知识查询引导\n"
+        "涉及方案设计、编码实现、故障排查时，先查 wiki-vault 相关实践：\n"
+        "- 路径：/Volumes/KnowledgeBase/wiki-vault/\n"
+        "- 速查：index.md → grep 关键词 → summary 字段 → 按需读全文\n"
+        "- 查不到：在 _meta/knowledge-gaps.md 记录"
+    )
+
+    def render(self, context: PromptContext) -> str:
+        return self.WIKI_GUIDE
+
+    def should_include(self, context: PromptContext) -> bool:
+        return True
+```
+
+#### 三种 handler 改动
+
+每种 handler 的 `get_sections()` 末尾加 `WikiGuideSection()`：
+
+```python
+# TaskHandler
+def get_sections(self) -> list:
+    return [
+        TaskContextSection(),
+        PriorOutputsSection(),
+        RoleSkillSection(),
+        TaskApiSection(),
+        TaskConstraintsSection(),
+        WikiGuideSection(),          # ← 新增
+    ]
+
+# MailHandler
+def get_sections(self) -> list:
+    return [
+        MailContextSection(),
+        MailApiSection(),
+        MailConstraintsSection(),
+        WikiGuideSection(),          # ← 新增
+    ]
+
+# ToolchainHandler
+def get_sections(self) -> list:
+    return [
+        ToolchainContextSection(),
+        ToolchainApiSection(),
+        ToolchainConstraintsSection(),
+        WikiGuideSection(),          # ← 新增
+    ]
+```
+
+#### 为什么三种 handler 都需要
+
+- **TaskHandler**：executor 做方案/编码，最需要查实践
+- **ToolchainHandler**：CI 失败排查、部署问题，有相关运维实践可参考
+- **MailHandler**：request 类型回复杂问题时也可能需要查已有经验
+
+#### token 开销
+
+WikiGuideSection 固定 ~60 字（~30 tokens），对 L2 预算影响可忽略。
+
+### D16-4：L3 被动参考层 — wiki-query Skill
+
+#### 现状
+
+`wiki-query` Skill 已部署在 `~/.sanguo_projects/sanguo_mozi/skills/wiki/wiki-query/SKILL.md`，description 包含中文触发词：
+
+> 调查、研究、分析、优秀实践、最佳实践、经验、怎么做X、有没有X的经验、以前怎么处理的
+
+#### 触发机制
+
+Agent 通过 extraDirs 加载 Skill header（name + description），按 Description 匹配自主 `read` 全文。这是标准 L3 行为，和 #11 设计一致。
+
+#### 待确认：extraDirs 子目录递归
+
+wiki-query 在 `skills/wiki/wiki-query/` 子目录下。需确认 moziplus spawn 子 agent 时 extraDirs 是否递归扫描子目录。如果不递归，需要：
+- 方案 A：把 wiki-query 移到 `skills/` 顶层
+- 方案 B：配置 extraDirs 包含 `skills/wiki/` 子目录
+
+### D16-5：知识 gap 记录 + 定时任务（运维层）
+
+> 不属于上下文分层体系，是独立的运维流程。
+
+#### gap 记录机制（已有基础设施）
+
+- **位置**：`/Volumes/KnowledgeBase/wiki-vault/_meta/knowledge-gaps.md`
+- **格式**：`- [日期] Agent名查"主题" → 待处理`
+- **已有 20+ 条历史记录**，处理后标注 `→ 已建立 ✅`
+
+wiki-query Skill 的 Step 5 已内置 gap 记录逻辑。
+
+#### 定时任务（已有 cron 基础）
+
+| 任务 | 时间 | 内容 | 状态 |
+|------|------|------|------|
+| wiki-daily-update | 每天 04:00 | 处理 knowledge gaps + 当天经验总结 → 写入 wiki-vault | ✅ 已有 cron，需完善 |
+| pangtong-vault-sync | 每天 05:00 | 同步 wiki-vault 到 agent workspace | ✅ 已有 |
+
+**wiki-daily-update 完善内容**：
+1. 读取 knowledge-gaps.md 中"待处理"条目
+2. 对每个 gap：搜索 knowledge_base 是否有相关源码/文档 → 有则提炼写入 wiki-vault
+3. 搜索最近一天的 jsonl 日志，提取有价值的经验
+4. 新建或更新 wiki-vault 页面
+5. 更新 knowledge-gaps.md（标记为"已建立 ✅"或"无KB内容，跳过"）
+
+### D16-6：和 #11 各层关系总结
+
+| #11 层级 | #11 原始定义 | 知识注入贡献 | 本设计 |
+|---------|------------|------------|--------|
+| L0 铁律 | GATE 门控 + Delegation + 安全底线 | wiki 查询铁律 | ✅ D16-1 |
+| L1 角色 | SOUL.md + AGENTS.md + TOOLS.md + MEMORY.md | TOOLS.md 速查表 + SOUL.md Red Flags | ✅ D16-2 |
+| L2 引擎 | 任务上下文 + 角色操作规范 + 硬约束 | WikiGuideSection 通用段 | ✅ D16-3 |
+| L3 参考 | A/B/C/D 类 Skill，靠 Description 触发 | wiki-query Skill | ✅ D16-4 |
+| 运维 | — | gap 闭环 cron job | ✅ D16-5 |
+
+### D16-7：为什么不做 PromptComposer 自动注入知识全文
+
+1. **token 浪费**：每次任务都注入可能不相关的知识
+2. **覆盖范围有限**：只影响 moziplus 子任务 Agent
+3. **Agent 主动查询更精准**：知道自己缺什么知识，按需查询
+
+## 四、改动清单
+
+### 4.1 已完成 ✅
+
+| 改动 | 文件 | 层级 | 说明 |
+|------|------|------|------|

+| knowledge-gaps.md | `_meta/knowledge-gaps.md` | 运维 | 已有 20+ 条记录 |
+| wiki-daily-update cron | cron job | 运维 | 每天 04:00，需完善处理逻辑 |
+| pangtong-vault-sync cron | cron job | 运维 | 每天 05:00 |
+
+### 4.2 待实现
+
+| 改动 | 文件 | 层级 | 说明 |
+|------|------|------|------|
+| L0 wiki 铁律 | Hook 注入配置（`prependContext`） | L0 | 新增 `<wiki-rule>` 段 |
+| SOUL.md Red Flags | 各 Agent workspace SOUL.md | L1 | 知识查询 Red Flags 表 |
+| WikiGuideSection | `prompt_composer.py` 或独立文件 | L2 | 通用 PromptSection，三种 handler 共用 |
+| TaskHandler 注入 | `task_handler.py` `get_sections()` | L2 | 末尾加 `WikiGuideSection()` |
+| MailHandler 注入 | `mail_handler.py` `get_sections()` | L2 | 末尾加 `WikiGuideSection()` |
+| ToolchainHandler 注入 | `toolchain_handler.py` `get_sections()` | L2 | 末尾加 `WikiGuideSection()` |
+| extraDirs 递归确认 | moziplus spawn 配置 | L3 | 确认 wiki-query 子目录可被发现 |
+| wiki-daily-update 完善 | cron job 脚本 | 运维 | gap 处理 + jsonl 经验提取 |
+
+### 4.3 不做
+
+| 项目 | 原因 |
+|------|------|
+| PromptComposer 知识全文注入 | token 浪费，Agent 主动查询更精准 |
+| experiences 表 | wiki-vault 已覆盖，不重复建设 |
+| 新 Skill（除 wiki-query 外） | wiki-query 已有，不需要新的 |
+
+## 五、风险
+
+| 风险 | 概率 | 缓解 |
+|------|------|------|
+| Agent 不主动查 wiki | 中 | L0 铁律强制 + L2 引导 + L3 Description 触发，三层保障 |
+| wiki-query 在子目录不被 extraDirs 发现 | 中 | 确认后决定移顶层或配置子目录 |

+## 1. 背景与目标
+
+### 1.1 问题
+
+1. **blackboard_routes.py 膨胀**：572 行、22 个路由，task/comment/output/review/event/decision/observation/archive 全堆一个文件，维护困难
+2. **前端 N+1 请求**：打开 TaskModal 需要 5 次独立请求（task + events + subtasks + progress + comments），影响前端性能
+3. **工具链事件无前端展示**：`_toolchain` DB 隔离已完成，但前端无对应 Tab，工具链事件只能通过 Agent 收 Mail 感知
+
+### 1.2 目标
+
+1. 按领域拆分 blackboard_routes.py → 3 个文件
+2. 实现细粒度 expand 聚合接口，前端 1-2 次请求拿全任务详情
+3. 新增工具链 Tab（列表 + 详情 + 搜索栏）
+4. 任务列表支持标题搜索
+
+### 1.3 不做
+
+- checkpoint_routes.py 不纳入拆分（已独立）
+- mail_routes / toolchain_routes / project_routes 不动
+- SQL JOIN / batch query 性能优化（当前 SQLite 单写下多次查询可接受）
+
+---
+
+## 2. 后端 API 文件拆分
+
+### 2.1 拆分方案（方案 B 调整版，司马懿确认）
+
+| 新文件 | 内容 | 预估行数 |
+|--------|------|---------|
+| `task_routes.py` | task CRUD + create(含 AI 标题) + patch + progress + claim + status(含广播) + archive + archive-done | ~280 |
+| `task_relation_routes.py` | comments + outputs(含文件写入) + reviews + decisions + observations + events + experiences + summary | ~250 |
+| `shared.py` | `_bb()` / `_q()` / `_validate_project()` / `_task_to_dict()` / `_init_agent_ids()` / `_extract_mentions()` / 常量导入 | ~30 |
+
+### 2.2 路由分配明细
+
+**task_routes.py**（10 个路由）：
+
+| 路由 | 方法 | 函数 | 说明 |
+|------|------|------|------|
+| `/tasks` | GET | `list_tasks` | 列表（新增 `q` 搜索参数） |
+| `/tasks` | POST | `create_task` | 创建（含 `_generate_title`） |
+| `/tasks/{tid}` | GET | `get_task` | 详情（含 expand 聚合） |
+| `/tasks/{tid}` | PATCH | `patch_task` | 更新 |
+| `/tasks/{tid}/progress` | GET | `task_progress` | 进度 |
+| `/tasks/{tid}/claim` | POST | `claim_task` | 认领 |
+| `/tasks/{tid}/status` | POST | `update_status` | 状态流转（含广播逻辑） |
+| `/tasks/{tid}/archive` | POST | `archive_task` | 归档 |
+| `/tasks/archive-done` | POST | `archive_done_tasks` | 批量归档 |
+
+**task_relation_routes.py**（13 个路由）：
+
+| 路由 | 方法 | 函数 | 说明 |
+|------|------|------|------|
+| `/tasks/{tid}/comments` | GET | `get_comments` | 评论列表 |
+| `/tasks/{tid}/comments` | POST | `add_comment` | 添加评论（含 @mention 提取） |
+| `/tasks/{tid}/outputs` | GET | `get_outputs` | 产出列表 |
+| `/tasks/{tid}/outputs` | POST | `write_output` | 写入产出（含文件写入逻辑） |
+| `/tasks/{tid}/decisions` | GET | `get_decisions` | 决策列表 |
+| `/tasks/{tid}/decisions` | POST | `add_decision` | 添加决策 |
+| `/tasks/{tid}/observations` | POST | `add_observation` | 添加观察 |
+| `/tasks/{tid}/reviews` | GET | `get_reviews` | 审查列表 |
+| `/tasks/{tid}/reviews` | POST | `add_review` | 添加审查 |
+| `/tasks/{tid}/events` | GET | `get_task_events` | 事件列表 |
+| `/tasks/{tid}/experiences` | GET | `get_task_experiences` | 经验列表 |
+| `/events` | GET | `get_events` | 项目级事件 |
+| `/summary` | GET | `task_summary` | 任务汇总 |
+
+### 2.3 shared.py 共享件
+
+从 blackboard_routes.py 提取到 shared.py：
+
+| 符号 | 类型 | 说明 |
+|------|------|------|
+| `_validate_project()` | function | 项目 ID 校验 |
+| `_bb()` | function | Blackboard 实例获取 |
+| `_q()` | function | Queries 实例获取 |
+| `_task_to_dict()` | function | Task → dict 序列化 |
+| `_init_agent_ids()` | function | Agent ID 初始化 |
+| `_extract_mentions()` | function | @mention 提取 |
+| `VALID_STATUSES` | import | 从 db.py 重导出 |
+| `OUTPUT_TYPES` | import | 从 db.py 重导出 |
+
+### 2.4 main.py 路由注册变更
+
+```python
+# 拆分前
+from src.api.blackboard_routes import router as blackboard_router
+app.include_router(blackboard_router)
+
+# 拆分后
+from src.api.task_routes import router as task_router
+from src.api.task_relation_routes import router as task_relation_router
+app.include_router(task_router)
+app.include_router(task_relation_router)
+```
+
+URL prefix 不变：所有路由仍是 `/api/projects/{pid}/...`，前端 URL 零改动。
+
+### 2.5 向后兼容
+
+- 删除 `blackboard_routes.py`，所有引用指向新文件
+- `expand=all` 保持兼容（内部映射为全量 expand）
+- 不改变任何 API 的请求/响应格式（仅文件组织变化）
+
+---
+
+## 3. expand 聚合接口
+
+### 3.1 设计
+
+`GET /api/projects/{pid}/tasks/{tid}?expand=comments,outputs,reviews,events,decisions`
+
+支持逗号分隔的细粒度选择，替代当前的 `expand=all`。
+
+### 3.2 返回格式
+
+```json
+{
+  "task": { "id": "...", "title": "...", "status": "working", ... },
+  "comments": {
+    "items": [...],
+    "total_count": 45,
+    "limit": 20
+  },
+  "events": {
+    "items": [...],
+    "total_count": 120,
+    "limit": 30
+  },
+  "outputs": [...],
+  "reviews": [...],
+  "decisions": [...]
+}
+```
+
+### 3.3 limit 策略
+
+| 关联资源 | expand 返回 | 分页支持 | 理由 |
+|----------|------------|---------|------|
+| comments | 最新 20 条 + total_count | `GET /comments?limit=50&offset=0` | 高频资源，长任务可能积累几十条 |
+| events | 最新 30 条 + total_count | `GET /events?limit=100&offset=0` | 运行几天可能上百条 |
+| outputs | 全部 | 不需要 | 通常 <5 条 |
+| reviews | 全部 | 不需要 | 通常 <5 条 |
+| decisions | 全部 | 不需要 | 通常 <5 条 |
+
+前端拿到 `total_count > items.length` 时显示"还有 N 条"，按需点击加载。
+
+### 3.4 实现伪码
+
+```python
+@router.get("/tasks/{task_id}")
+async def get_task(project_id: str, task_id: str,
+                   expand: Optional[str] = None):
+    bb = _bb(project_id)
+    task = bb.get_task(task_id)
+    if not task:
+        raise HTTPException(404, f"Task not found: {task_id}")
+
+    result = _task_to_dict(task)
+
+    if not expand:
+        return result
+
+    expand_list = expand.split(",") if expand != "all" else [
+        "comments", "outputs", "reviews", "events", "decisions"
+    ]
+
+    q = _q(project_id)
+
+    if "comments" in expand_list:
+        all_comments = bb.get_comments(task_id)
+        result["comments"] = {
+            "items": [dict(c.__dict__) for c in all_comments[-20:]],
+            "total_count": len(all_comments),
+            "limit": 20,
+        }
+
+    if "events" in expand_list:
+        all_events = q.task_events(task_id)
+        result["events"] = {
+            "items": all_events[-30:],
+            "total_count": len(all_events),
+            "limit": 30,
+        }
+
+    if "outputs" in expand_list:
+        result["outputs"] = [dict(o.__dict__) for o in bb.get_outputs(task_id)]
+
+    if "reviews" in expand_list:
+        result["reviews"] = [dict(r.__dict__) for r in bb.get_reviews(task_id)]
+
+    if "decisions" in expand_list:
+        result["decisions"] = [dict(d.__dict__) for d in bb.get_decisions(task_id)]
+
+    return result
+```
+
+### 3.5 性能分析
+
+| 场景 | 当前（无 expand） | expand 后 | 改善 |
+|------|-----------------|-----------|------|
+| 打开 TaskModal | 5 次 HTTP 请求 | 2 次（task+expand + subtasks） | -60% 请求 |
+| 单次 expand 响应体 | — | ~5-15KB（典型） | 一次大请求 < 五次小请求 |
+| DB 查询次数 | 5 次（各端点独立查） | 5 次（expand 内部循环） | 相同，暂不优化 |
+
+---
+
+## 4. 任务列表搜索
+
+### 4.1 设计
+
+`GET /api/projects/{pid}/tasks?q=关键词`
+
+在现有 `list_tasks` 基础上增加 `q` 查询参数，支持标题模糊搜索（SQL LIKE）。
+
+### 4.2 实现
+
+```python
+@router.get("/tasks")
+async def list_tasks(project_id: str, q: Optional[str] = None, ...):
+    bb = _bb(project_id)
+    tasks = bb.list_tasks(status=status, ...)
+
+    if q:
+        q_lower = q.lower()
+        tasks = [t for t in tasks if q_lower in (t.title or "").lower()]
+
+    return {"tasks": [_task_to_dict(t) for t in tasks]}
+```
+
+**设计决策**：过滤在 Python 层做而非 SQL 层。
+- 理由：当前 `list_tasks` 已在 Python 层做 status 筛选，加一层 title 过滤一致性更好
+- 如果后续任务量大（>1000），再改为 SQL LIKE 查询
+
+---
+
+## 5. 前端：工具链 Tab
+
+### 5.1 Tab 定义
+
+```typescript
+// store.ts TabKey 新增
+| 'toolchain'
+
+// TAB_DEFS 新增（插在 settings 前面）
+{ key: 'toolchain', label: '工具链', icon: '⛓️' },
+```
+
+### 5.2 数据加载
+
+```typescript
+// store.ts 新增
+toolchainTasks: any[];
+loadToolchain: async () => {
+  const res = await fetch('/api/projects/_toolchain/tasks');
+  const data = await res.json();
+  set({ toolchainTasks: data.tasks || [] });
+}
+
+// Tab 切换时加载
+if (tab === 'toolchain') s.loadToolchain();
+```
+
+### 5.3 ToolchainPanel 组件
+
+仿 MailPanel 结构，三个区域：
+
+**搜索栏**（顶部）：
+- 文本输入框，输入关键词实时过滤列表
+- 调用 `GET /api/projects/_toolchain/tasks?q=关键词`
+
+**列表区**（左侧）：
+- 工具链事件列表（时间倒序）
+- 每条显示：标题 + 时间 + 状态标签
+- 点击选中，高亮当前选中项
+
+**详情区**（右侧）：
+- 选中事件的完整内容
+- 调用 `GET /api/projects/_toolchain/tasks/{tid}?expand=comments` 获取详情
+- 展示：标题、描述、状态、评论（action_report 等）
+
+### 5.4 和 Mail 的隔离
+
+| 维度 | Mail Tab | 工具链 Tab |
+|------|---------|-----------|
+| 数据源 | `_mail` 项目 | `_toolchain` 项目 |
+| 事件类型 | Agent 间通信（inform/request） | 系统事件（CI/PR/部署/Review） |
+| 搜索 | 无（邮件量不大） | 有（工具链事件频率高） |
+
+---
+
