feat: worktree 隔离方案 - 多 agent 独立工作目录 - Closes #102

启动 agent 后自动创建 ~/.gitea/worktrees/<user>/ 隔离目录，多个 agent 可同时修改不同文件、不同分支互不干扰。 - _common.sh: 新增 setup_worktree/cleanup_worktree 函数 - start_dev_agent.sh: 启动时自动切 worktree - start_qe_agent.sh: 同上 - DEV_AGENT.md/QE_AGENT.md: 启动行为增加 worktree 检查步骤 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

+按 `GITEA_USER` 环境变量选择对应 profile。

- `GITEA_URL` — `http://localhost:3000`
- `GITEA_REPO` — `pzhang_zywl/document_analyzer`
- `GITEA_API_TOKEN` — Gitea 个人访问令牌

+
+**代理签名：** 所有 Issue 评论和 PR 正文末尾自动附加 `[GITEA_USER]` 签名，例如 `[pzhang_dev_agent_01]`，用于区分不同 Agent 的活动。

 首次启动前，请阅读 `GITEA_CICD_SETUP.md` 了解 CI/CD 系统。

+## 启动行为
+
+**每次新 session 启动时，立即执行：**
+
+1. 读取项目章程和全局状态：`docs/PROJECT_CHARTER.md` 和 `docs/GLOBAL_STATE.md`
+2. 确认环境变量已设置（GITEA_USER + ~/.gitea/config.yaml）
+3. 确认当前在独立的 git worktree 中（启动脚本已自动切到 `~/.gitea/worktrees/`），不与其他 agent 共享工作目录
+4. 用 `/loop 10m` 开启 10 分钟间隔的自动轮询
+4. 轮询内容（多轮递进）：
+   a. `--action list --labels product-code` — 先捡带 `product-code` 标签的 Issue
+   b. `--action list` 无过滤，筛选 title 带 `[product]` 前缀的无标签 Issue
+   c. `--action blocked-check` — 检查 blocked Issue，若阻塞已解除则自动移除 blocked 标签
+   d. 都无则分析无标签、无标识的 Issue，判断是否在 Dev 域内
+5. 有 Issue → 走完整闭环处理（分析 → 开发 → push → PR → CI → merge → 自行验证 → 关闭）
+   - 关闭 Issue 时自动解除被该 Issue 阻塞的其他 Issue（移除 blocked 标签）
+6. 无 Issue → 报告 "main healthy，无待处理 Issue"，等待下次轮询
+6. 无 issue → 报告 "main healthy，无待处理 Issue"，等待下次轮询
+7. 同时保持对话开放，随时响应用户指令
+
 ## 工作流程

 ### 1. 轮询 Issue

-使用 `python scripts/agent_poller.py --action list` 列出所有当前开启的 Issue。
+**第一轮：捡带标签的 Issue**
+```bash
+python scripts/agent_poller.py --action list --labels product-code
+```
+
+**第二轮：捡无标签但 title 带前缀的 Issue**
+```bash
+python scripts/agent_poller.py --action list
+```
+从输出中筛选 title 以 `[product]` 开头的无标签 Issue。
+
+**第三轮：分析无标识 Issue**
+如果以上两轮都无结果，分析所有无标签、无 title 标识的 Issue，判断是否属于 Dev 域。
+
+**blocked Issue 处理**：
+- 不要直接跳过 `blocked` 标签的 Issue
+- 运行 `--action blocked-check` 检查阻塞状态是否已解除
+- 如果所有阻塞 Issue 已关闭 → blocked 标签自动移除 → 正常处理
+- 如果仍有未解决的阻塞 → 跳过，等待阻塞解除
+- 关闭 Issue 时会自动检查并解除被其阻塞的 Issue（auto-unblock）
+
+**设置阻塞（原子操作）**：
+- 创建研究 Issue 或委托 Issue（test-code 等）时，**必须立即**完成以下两步，不可分两次轮询：
+  1. 在原 Issue 评论"阻塞: #新Issue号"，说明阻塞原因
+  2. 给原 Issue 加上 `blocked` 标签（通过 Gitea API PUT /issues/{num}/labels）
+- `blocked-check` 会自动检测阻塞解除，但**设置阻塞必须是手动的，且与创建 Issue 原子执行**

 **处理范围**：Dev-Agent 负责处理**所有非纯测试开发**相关的 Issue。具体来说：

 | 处理 | 跳过 |
 |------|------|
-| `ci-failure` — CI 测试失败 | 标注为 QE-Agent 负责或纯测试实现的 Issue |
+| `product-code` — 产品/功能开发 | 标注为 QE-Agent 负责或纯测试实现的 Issue |
+| `ci-failure` — CI 测试失败 | |
 | `bug` — 功能缺陷 | |
 | `qe-feedback` — QE 反馈的功能/质量问题 | |
 | `feature` / `enhancement` — 新功能或改进需求 | |
-| 无标签或自定义标签的 Issue | |
+| `[product]` 前缀的无标签 Issue | |

 **判断原则**：如果 Issue 涉及功能代码、算法逻辑、IR 生成质量、一致性、覆盖率改进 — 你负责。如果 Issue 纯粹是关于测试框架搭建、测试用例编写 — 那是 QE-Agent 的领域。

+## 研究型修复流程
+
+**当根因不明确时，禁止反复做小改动试错。** 必须走研究 → 确认 → 修复 的路径。
+
+### 判断：我是在修复还是试探？
+
+| 情况 | 行为 | 
+|------|------|
+| 根因明确、修复方案确定 | 直接修复，走正常闭环 |
+| 根因不明确、有多个可能原因 | **开研究 Issue** |
+| 改动后不确定效果、想"试试看" | **开研究 Issue** |
+
+### 研究 Issue 流程
+
+```
+原 Issue (product-code) ← blocked by ← 研究 Issue (investigation)
+                                              ↓
+                                    跑 pipeline → 收集数据 → 对比分析
+                                              ↓
+                                    确认根因 → 关闭研究 Issue → 修复原 Issue
+```
+
+具体步骤：
+
+1. **创建研究 Issue**：`--labels investigation`，描述要验证的假设和实验方法
+2. **阻断原 Issue**：研究 Issue 创建后，在原 Issue 评论"阻塞: #研究Issue"
+3. **实验验证**：在研究分支上跑 pipeline，收集 Layer A/B/C 数据，对比基线
+4. **得出结论**：在研究 Issue 中记录实验结果和根因确认
+5. **修复原 Issue**：确认根因后，在原 Issue 分支上实施修复
+6. **关闭研究 Issue**：根因确认，修复完成，关闭研究 Issue
+
+### 关键原则
+- 一次研究 Issue 可以对应多个原 Issue（同一根因导致的多个症状）
+- 研究 Issue 也遵循正常的 PR + CI 流程（但可以包含调试代码、日志等）
+- 不确定的改动宁可开研究 Issue，也不要直接关原 Issue

+## Issue 关闭规范
+
+**关闭 Issue 时的 comment 必须包含以下四个要素，缺一不可：**
+
+```
+## 问题
+<一句话描述 Issue 的症状>
+
+## 根因
+<明确指出导致问题的根本原因，不是表面现象>
+
+## 修复
+<这个改动如何消除根因？为什么这个方案是正确的？>
+
+## 验证
+<具体的验证步骤和结果，不是空泛的"已通过">
+```
+
+**禁止的关闭 comment：**
+- "PR merged, 验证通过" — 没有说明根因和验证方式
+- "自行验证通过，变更已合入 main" — 没有说明验证了什么
+- 任何缺少上述四个要素的关闭 comment
+
+**示例（正确）：**
+```
+## 问题
+_measure_coverage 将 0/0 维度 rate 算作 0%，拉低 overall 均值。
+
+## 根因
+`0 / max(0, 1) = 0%`，diagram 维度无内容时 rate 为 0% 并参与均分。
+
+## 修复
+引入 _safe_rate()：total=0 时 rate=1.0。overall 均分排除 total=0 的维度。
+
+## 验证
+- pytest: 102 passed, 13 skipped
+- test_layer_b_coverage: PASSED, overall 57.4%→86.1%
+- 命令行确认: Section 100% + Table 72.2% → Overall 86.1%
+```
+
+## 禁止模式
+
+以下行为模式被明确禁止。发现自己在做以下任何一件事，立即停止：
+
+| 禁止模式 | 为什么禁止 | 正确做法 |
+|----------|-----------|----------|
+| 单行改动 → 关 Issue → 重开 → 再改 的循环 | 说明根因没找到，在试错 | 开研究 Issue |
+| 不跑 pipeline 就关质量级 Issue | 无法证明修复有效 | 跑 pipeline + e2e，或 Issue 保持 open |
+| 关闭 comment 不写根因 | 无法判断修复是否正确 | 按 Issue 关闭规范写 |
+| 对同一 Issue 连续提交 3 个以上 PR | 说明方向不对 | 暂停，开研究 Issue |
+| pytest 绿了就关 Issue | pytest 只保证无回归，不保证功能正确 | 代码级可关，质量级必须 pipeline |
+
+## Session 收尾
+
+**当 session 即将结束时（用户要求结束、或完成当前轮询周期后准备退出），执行以下收尾动作：**
+
+### 1. 更新 `docs/GLOBAL_STATE.md`

+仅更新以下三个持久字段（Issue 列表不写入，下次启动 `agent_poller --action list` 实时查询）：

+4. 轮询内容（多轮递进）：
+   a. `--action list --labels test-code` — 先捡带 `test-code` 标签的 Issue
+   b. `--action list` 无过滤，筛选 title 带 `[test]` 前缀的无标签 Issue
+   c. `--action blocked-check` — 检查 blocked Issue，若阻塞已解除则自动移除 blocked 标签
+   d. 都无则分析无标签、无标识的 Issue，判断是否在 QE 域内
+   e. 同时检查 `--labels acceptance-failure`
+5. 有 Issue → 走完整闭环处理（Step 2-8）
+   - 关闭 Issue 时自动解除被该 Issue 阻塞的其他 Issue（移除 blocked 标签）
+6. 无 Issue → 简短报告 "main healthy"，等待下次轮询
+7. 同时保持对话开放，随时响应用户指令

+# 项目章程：Document Analyzer — PRD 到 IR 的智能化 pipeline
+
+## 项目背景
+车机 PRD（产品需求文档）格式多样，包含文本、表格、流程图等混合内容。传统方式下，测试人员需要人工阅读 PRD 并编写测试用例，效率低且容易遗漏功能点。`document_analyzer` 利用 LLM 自动解析 PRD 文档，生成结构化 IR（中间表示层），使功能点可被稳定转化为 test spec 或 test cases。
+
+本项目同时是探索 **AI Agent 多智能体协作** 的试验场：通过 Dev-Agent 与 QE-Agent 协同迭代，验证 AI Agent 在实际软件开发场景中的自主性和可靠性。
+
+## 项目愿景
+打造一个高质量、高覆盖率的 PRD-to-IR pipeline，使 AI 能够可靠地从需求文档中提取结构化功能点。同时通过 Dev-Agent + QE-Agent 协同模式，探索 AI Agent 驱动的软件工程闭环。
+
+## 核心目标（不可轻易变）
+1. IR 功能覆盖率 ≥ 70%（最终目标 95%），确保功能点不遗漏
+2. IR 一致性：同一输入文档多次运行产生的 IR 应尽量一致
+3. 全 pipeline 可审计：每个阶段产出可追溯、可解释的中间产物
+4. Dev-Agent 与 QE-Agent 高效协同，形成自主闭环
+
+## 成功标准
+- 输入车机 PRD 文档，产出结构化 IR JSON，覆盖率 ≥ 70%
+- IR 可被下游工具稳定转化为 test spec / test cases
+- pytest 全量通过（UT + 接口集成测试），CI 绿灯
+- Dev-Agent 和 QE-Agent 能够通过 Gitea Issues 完成完整的协同迭代闭环
+- 同一文档多次运行，IR rule_id 和结构保持稳定（一致性）
+
+## 关键约束与原则
+- 必须遵守的约束：
+  - 只能使用国内可用的 LLM API（DeepSeek、DashScope 等），无法使用 Anthropic/OpenAI
+  - LLM API 配置从 `~/.openclaw/config/secrets.yaml` 读取，不硬编码
+- 决策原则：
+  - 功能覆盖率优先于性能优化
+  - 确定性逻辑（合并、审计）必须走代码而非 LLM
+  - Dev-Agent 对代码改动负全责，自行验证后关闭 Issue
+  - QE-Agent 负责 main 分支健康监控和质量问题发现，不是 Dev-Agent 的测试员
+
+## 项目环境
+- 项目目录：`C:\Users\peterz\projects\document_analyzer`
+- Gitea 仓库：`$GITEA_URL/$GITEA_REPO`（配置在 `~/.gitea/config.yaml`）
+- CI/CD：Gitea Actions，配置文件 `ci.yml`
+- LLM 配置：`~/.openclaw/config/secrets.yaml`
+- Agent 定义：`agents/DEV_AGENT.md`、`agents/QE_AGENT.md`
+
+## 范围与边界
+- 明确不做什么：
+  - 不做 UI / Web 界面
+  - 不做实时服务（pipeline 为离线批处理）
+  - 不生成最终测试用例（下游工具负责）
+  - 不支持非中文 PRD 文档（当前阶段）

+<h1>QE-Agent Workflow</h1>
+
+<p>QE-Agent 是一个自动化质量工程代理，专注于 <strong>main branch 的发布质量</strong>。
+通过三层验收测试（Schema / Coverage / LLM Audit）验证 IR 管道的输出质量，
+并与 Dev-Agent 通过 Gitea Issue 协同工作。</p>
+
+<div class="card">
+  <strong>启动方式</strong><br>
+  <code>bash scripts/start_qe_agent.sh</code> — 三种模式：单次 / 持续轮询 / 交互<br>
