+# Phase 1 Plan 2: Core Pipeline Schemas Summary
+
+**定义工作流管道核心 Schema (StepInput, StepOutput, StepStatus, StepRecord, WorkflowState, StepDefinition)，使用 Pydantic v2 实现类型安全和自动验证，100% 测试覆盖率**
+
+## Performance
+
+- **Duration:** 7 min
+- **Started:** 2026-03-13T09:02:08Z
+- **Completed:** 2026-03-13T09:09:01Z
+- **Tasks:** 3
+- **Files modified:** 6
+
+## Accomplishments
+- 建立核心 Schema 体系，支持步骤输入/输出验证
+- WorkflowState 实现步骤状态管理方法
+- 37 个测试用例，100% 代码覆盖率
+- 完整的 JSON 序列化/反序列化支持
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create package structure and write failing tests** - `85413bc` (test)
+2. **Task 2: Implement core schemas** - `2caddd7` (feat)
+3. **Task 3: Refactor and verify JSON serialization** - `7ffaafd` (refactor)
+
+_Note: TDD tasks have multiple commits (test -> feat -> refactor)_
+
+## Files Created/Modified
+- `kb_pipeline/__init__.py` - 包初始化和公共接口导出
+- `kb_pipeline/schemas.py` - 核心 Schema 定义 (163 行)
+- `tests/test_pipeline/__init__.py` - 测试包初始化
+- `tests/test_pipeline/conftest.py` - Pytest fixtures
+- `tests/test_pipeline/test_schemas.py` - Schema 测试 (375 行, 37 个测试)
+- `pytest.ini` - Pytest 配置 (pythonpath 设置)
+
+## Decisions Made
+- 使用 Pydantic v2 BaseModel 作为 Schema 基类
+- StepStatus 使用 str Enum 便于 JSON 序列化
+- WorkflowState 方法直接操作 steps 字典，简化状态管理
+- 创建 pytest.ini 配置 pythonpath，避免 PYTHONPATH 环境变量
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Created virtual environment and installed dependencies**
+- **Found during:** Task 1 (test collection)
+- **Issue:** pytest 未安装，系统 Python 禁止直接安装包
+- **Fix:** 创建 .venv 虚拟环境，安装 pytest 和 pydantic
+- **Files modified:** .venv/ (新目录)
+- **Verification:** pytest 成功运行测试
+- **Committed in:** N/A (环境配置，未提交到版本控制)
+
+**2. [Rule 3 - Blocking] Added pytest.ini for PYTHONPATH configuration**
+- **Found during:** Task 2 (test execution)
+- **Issue:** 模块导入失败，kb_pipeline 未在 Python 路径中
+- **Fix:** 创建 pytest.ini 配置 pythonpath = .
+- **Files modified:** pytest.ini
+- **Verification:** 测试无需设置环境变量即可运行
+- **Committed in:** `2caddd7` (Task 2 commit)
+
+---
+
+**Total deviations:** 2 auto-fixed (2 blocking)
+**Impact on plan:** 所有修复均为必要的开发环境配置，未影响计划功能
+
+## Issues Encountered
+None - TDD 流程顺利执行
+
+## User Setup Required
+None - 无外部服务配置要求
+
+## Next Phase Readiness
+- 核心 Schema 定义完成，可为后续步骤提供类型安全验证
+- WorkflowState 状态管理方法可用于 01-03 计划的状态持久化
+- pytest 和 venv 配置完成，后续测试可直接使用
