使用 dataclass 定义 ParsedLink，简洁且支持默认值

短链解析使用 requests.head(allow_redirects=True) 获取最终 URL

无法识别的 URL 返回 None 而不是抛异常，便于调用方处理

幂等检查返回 (bool, list[Path]) 元组，提供详细的已存在文件信息

Pattern 1: LinkParser.parse(url) -> Optional[ParsedLink] - 统一解析入口

Pattern 2: IdempotencyChecker.check_exists(dir, id, platform) -> (bool, list) - 幂等检查模式

Plan metadata: (pending)

Note: TDD tasks had test file created before implementation

Files Created/Modified

kb_pipeline/link_parser.py - 统一链接解析器，支持B站/知乎URL
kb_pipeline/idempotency.py - 幂等检查机制
tests/test_pipeline/test_link_parser.py - LinkParser 单元测试 (15 tests)
tests/test_pipeline/test_idempotency.py - IdempotencyChecker 单元测试 (8 tests)
kb_pipeline/__init__.py - 添加新模块导出

Decisions Made

使用 dataclass 定义 ParsedLink，简洁且支持默认值
短链解析使用 requests.head(allow_redirects=True)
无法识别的 URL 返回 None 而不是抛异常
幂等检查返回元组 (all_exist, existing_files)

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Installed missing requests dependency

Found during: Task 1 (LinkParser implementation)
Issue: requests 模块未安装，import 失败
Fix: 使用 uv pip install requests 安装依赖
Files modified: venv (certifi, charset-normalizer, idna, requests, urllib3)
Verification: 测试全部通过
Committed in: dd94f06 (Task 1 commit)

Total deviations: 1 auto-fixed (1 blocking) Impact on plan: 必要的依赖安装，无范围蔓延

Issues Encountered

None - plan executed smoothly after dependency installation

User Setup Required

None - no external service configuration required.

Next Phase Readiness

LinkParser 和 IdempotencyChecker 已就绪
可用于后续平台适配器的 URL 解析和重复处理防护
测试覆盖率 95%

Phase: 02-platform-skills Completed: 2026-03-13
