+# CI 大量失败根因排查报告
+
+**排查时间：** 2026-07-13
+**排查人：** 构建服务器运维Agent
+**范围：** 最近15次 CI run（PR #258~#265 + develop 分支多次 push）
+
+## 一、整体概况
+
+最近 20 次 CI run 中 16 次失败，失败率 **80%**。失败集中在 3 个 Job：
+
+| Job | 失败率 | 根因类型 |
+|-----|--------|----------|
+| Validate Code Quality | 100% | black 代码格式检查失败 |
+| Unit Tests | 100% | 测试断言未同步国际化改动 |
+| Integration Tests | 100% | 密码重置接口变更未同步测试 |
+| Frontend Lint | 20% | 各 PR 代码质量问题 |
+
+**结论：3 个全局性失败点导致所有 PR CI 全红，不是代码本身问题，是基础设施/测试用例滞后。**
+
+---
+
+## 二、详细根因分析
+
+### 1. Validate — black 格式检查失败
+
+**现象：**
+```
+would reformat scripts/check_migration_safety.py
+1 file would be reformatted, 369 files would be left unchanged.
+Oh no! 💥 💔 💥
+```
+
+**根因：**
+`scripts/check_migration_safety.py` 文件不符合 black 格式化规范。该文件是最近新增的迁移安全检查脚本，提交前未本地跑 black 格式化。
+
+**影响范围：** 所有 PR 及 develop 分支，全量失败。
+
+**修复方案：**
+```bash
+black scripts/check_migration_safety.py
+```
+
+---
+
+### 2. Unit Tests — 1 个用例失败
+
+**现象：**
+```
+FAILED tests/unit/test_asset_library_delete.py::TestDeleteAssetLibrary::test_delete_library_access_denied
+  AssertionError: assert 'Access denied' in '无权访问该项目'
+```
+
+**统计：** 1442 passed, 1 failed
+
+**根因：**
+项目之前做了国际化（i18n）改造，错误信息从英文改成了中文，但对应的单元测试断言仍然检查英文 "Access denied"，导致断言失败。
+
+**影响范围：** 所有 PR 及 develop 分支，全量失败。
+
+**修复方案：**
+修改 `tests/unit/test_asset_library_delete.py` 中的断言，将 `'Access denied'` 改为 `'无权访问该项目'`，或改为断言 HTTP 状态码（403）而不是错误消息文本。
+
+---
+
+### 3. Integration Tests — 1 个用例失败
+
+**现象：**
+```
+FAILED tests/integration/test_auth.py::TestPasswordReset::test_request_password_reset_success
+  assert 404 in (200, 202)
+```
+
+**统计：** 45 passed, 1 failed, 13 deselected, 2 rerun
+
+**根因：**
+密码重置请求接口（`POST /auth/password-reset/request` 或类似路由）返回 404，说明该接口已被移除、路由变更，或对应的功能模块暂时被注释/下线。
+
+**影响范围：** 所有 PR 及 develop 分支，全量失败。
+
+**修复方案：**
+- 如果接口确实下线了：删除或 skip 这个测试用例
+- 如果是路由改了：更新测试中的 API 路径
+- 如果是功能待开发：标记为 `@pytest.mark.skip` 并加上 TODO
+
+---
+
+## 三、修复优先级
+
+| 优先级 | 问题 | 修复难度 | 预估时间 |
+|--------|------|----------|----------|
+| P0 | black 格式检查失败 | ⭐ | 5分钟 |
+| P0 | 单元测试国际化断言失败 | ⭐ | 10分钟 |
+| P1 | 集成测试密码重置接口404 | ⭐⭐ | 30分钟（需确认接口状态） |
+
+**建议：** 先修前两个 P0（能让 2/3 的 job 变绿），再处理密码重置那个。
+
+---
+
+## 四、Runner 执行情况观察
+
+- 当前 9 个 Runner 全部在线（构建服务器 4 个 + 新服务器 5 个）
+- 失败的 Job 都是在构建服务器的 Runner 上执行的（xiaoxia-ci-runner-2/3 等）
+- 新服务器 5 个 Runner 目前全部空闲（标签修复后首次接任务可能需要时间）
+- 并发能力充足，瓶颈在代码/测试本身，不在 Runner 资源

+# 三台服务器 Runner 分工规划
+
+**制定日期：** 2026-07-13
+**状态：** 规划中
+
+---
+
+## 一、现状总览
+
+当前共 9 个 Gitea Actions Runner，分布在 3 台服务器上：
+
+| 服务器 | IP | 配置 | Runner 数量 | 当前状态 |
+|--------|-----|------|-------------|----------|
+| 构建服务器 | 114.55.236.178 | 4核 / 7.1G RAM / 49G NVMe | 4个（ID: 8, 42, 46, 47） | ✅ 在线 |
+| 新CI服务器 | 116.62.226.203 | 8核 / 14G RAM | 5个（ID: 58-62） | ✅ 在线 |
+| 业务服务器 | 47.98.113.167 | - | 0个（旧3个已下线） | ⚠️ 待规划 |
+
+**所有 Runner 共用标签：** `saas`, `runtime-builder`, `host`, `ubuntu-latest`
+
+---
+
+## 二、问题分析
+
+### 2.1 标签无区分
+所有 Runner 标签完全一致，CI 任务随机分配到任意 Runner，导致：
+- 构建任务（Build）可能跑到配置低的机器上，构建慢
+- 代码检查任务占着构建服务器，影响构建速度
+- 业务服务器跑 CI 影响线上服务稳定性
+
+### 2.2 资源浪费
+- 新服务器 8核14G 跑 validate/lint 有点大材小用
+- 构建服务器 4核7G 跑 Docker 构建偏紧张
+
+---
+
+## 三、规划方案
+
+### 3.1 分工原则
+
+| 服务器 | 角色 | 主要任务类型 | 标签策略 |
+|--------|------|-------------|----------|
+| **构建服务器** (114.55.236.178) | 构建专机 | Build Staging / Build Production / Docker 镜像构建 | 保留 `saas` + `host`，新增 `build-only` |
+| **新CI服务器** (116.62.226.203) | 代码检查专机 | Validate / Unit Tests / Integration Tests / Frontend Lint | 保留 `saas` + `host`，新增 `ci-check` |
+| **业务服务器** (47.98.113.167) | 部署专机 | Deploy Staging / Deploy Production / E2E Tests | 保留 `saas` + `host`，新增 `deploy-only` |
+
+### 3.2 具体配置
+
+#### 构建服务器（4个 Runner）
+- **数量：** 3个（从4个缩减，释放资源给构建缓存）
+- **标签：** `saas`, `host`, `build-only`, `ubuntu-latest`
+- **负责 Job：**
+  - `build-staging`
+  - `build-production-runtime-images`
+  - 其他需要 Docker buildx 的任务
+
+#### 新CI服务器（5个 Runner）
+- **数量：** 5个（保持不变）
+- **标签：** `saas`, `host`, `ci-check`, `ubuntu-latest`
+- **负责 Job：**
+  - `validate`
+  - `unit-tests`
+  - `integration-tests`
+  - `frontend-lint`
+  - 安全扫描（gitleaks / pip-audit / vulture 等）
+
+#### 业务服务器（1-2个 Runner）
+- **数量：** 1-2个（逐步替换旧的3个）
+- **标签：** `saas`, `host`, `deploy-only`, `ubuntu-latest`
+- **负责 Job：**
+  - `deploy-staging`
+  - `deploy-production`
+  - `staging-e2e` / `production-e2e`
+  - `staging-api-tests`
+
+---
+
+## 四、实施步骤
+
+### Phase 1: 标签打标（低风险，立即做）
+1. 新服务器 5 个 Runner 添加 `ci-check` 标签
+2. 构建服务器保留 3 个 Runner，添加 `build-only` 标签
+3. 业务服务器部署 1 个新 Runner，标签 `deploy-only`
+
+### Phase 2: Job 路由调整（中风险，逐步来）
+1. validate / unit-tests / integration-tests / frontend-lint 改为 `runs-on: ci-check`
+2. build-staging / build-production 改为 `runs-on: build-only`
+3. deploy-* / e2e 改为 `runs-on: deploy-only`
+
+### Phase 3: 旧 Runner 下线
+- 业务服务器旧的 3 个 Runner 确认无任务后下线
+- 构建服务器多余的 1 个 Runner 迁移到新服务器
+
+---
+
+## 五、并发配置优化建议
+
+### 5.1 当前并发情况
+- 首发并行 Job：validate + unit-tests + frontend-lint（3个并行）
+- integration-tests 依赖 validate（串行，浪费资源）
+- 无 concurrency 限制，同一分支多次 push 会重复跑
+
+### 5.2 优化建议
+
+**1. integration-tests 改为与 unit-tests 并行**
+```yaml
+# 当前
+integration-tests:
+  needs: validate  # 没必要等validate
+
+# 优化后
+integration-tests:
+  needs: []  # 直接和unit-tests并行跑
+```
+
+**2. 增加分支级 concurrency，取消重复构建**
+```yaml
+concurrency:
+  group: ${{ github.workflow }}-${{ github.ref }}
+  cancel-in-progress: true
+```
+同一 PR 多次 push 时，取消旧的构建，只跑最新的。
+
+**3. Build Staging 移出 PR 门禁**
+- 已在阶段二优化中完成（PR #245）
+- Build Staging 只在 develop/main 上异步构建
+
+---
+
+## 六、预期收益
+
+| 指标 | 当前 | 优化后 | 提升 |
+|------|------|--------|------|
+| PR CI 总时长 | ~8-12分钟 | ~4-6分钟 | ⏱️ 缩短 40-50% |
+| 构建速度 | 可能抢到慢机器 | 固定高配构建机 | 🚀 更稳定更快 |
+| 线上稳定性 | CI和业务抢资源 | 部署独立Runner | 🛡️ 隔离保障 |
+| Runner 利用率 | 随机分配 | 按任务类型调度 | 📈 更合理 |
