Human Verification Required
The following items need manual verification:
1. End-to-End B站视频处理
Test: 运行 python -m kb_workflow process "https://www.bilibili.com/video/BV1xxx" 处理真实B站视频
Expected:
- 成功生成 analysis.md 文件
- 文件包含正确的 YAML frontmatter（标题、作者、时长、bvid、url）
- 内容部分包含分段后的字幕文本，无时间戳
- 不包含深度分析内容（无时间轴、无关键见解等）
Why human: 需要真实的网络连接和B站视频访问权限
2. ASR 纠错效果验证
Test: 处理包含明显语音识别错误的字幕文件
Expected:
- 明显的同音字错误被纠正
- 正确文本不被过度修改
- AI 不可用时返回原文
Why human: 需要配置 AI API 密钥和验证纠错质量
3. 知乎处理流程不受影响
Test: 运行 python -m kb_workflow process "https://zhuanlan.zhihu.com/p/xxx" 处理知乎文章
Expected:
- 使用 AnalyzeProcessor 而非 SRTProcessor
- 生成包含深度分析的 Markdown
- 处理流程与 Phase 12 之前一致
Why human: 需要真实的网络连接和知乎访问权限
Test Results
tests/test_srt_processor.py - 20 tests - ALL PASSED
tests/test_bilibili_pipeline.py - 4 tests - ALL PASSED
Total: 24 tests passed in 0.33s
Summary
Phase 12 目标 完全达成：
- SRT 处理模块完整实现 - parser、segmenter、corrector 三个核心模块均已完成并通过测试
- Pipeline 集成成功 - B站视频使用 SRTProcessor，其他平台保持 AnalyzeProcessor
- 平台路由逻辑正确 -
is_bilibili_video检查确保仅 B站视频使用简化流程 - DeepAnalyzer 弃用警告已添加 - 提醒开发者 B站视频应使用 SRTProcessor
- 所有 24 个测试通过 - 覆盖解析、分段、纠错、处理器、Pipeline 集成
已知限制：
- 标签提取功能 (OUT-04) 当前返回空列表，有 TODO 注释标记未来可使用 LLM 增强。这不影响核心功能，因为元数据标签仍可通过其他方式获取。
