+## ◆ v1.5 B站字幕简化处理 (IN PROGRESS)
+
+**Milestone Goal:** 简化 B 站视频处理流程，基于 SRT 字幕生成易读的 Markdown 文档
+
+### Phase 12: SRT 简化处理器
+**Goal**: 实现 SRT 字幕处理，生成简化的 Markdown 文档，保留元数据和标签，移除深度分析
+**Depends on**: Phase 4 (Pipeline)
+**Requirements**: SRT-01, SRT-02, SRT-03, SRT-04, OUT-01, OUT-02, OUT-03, OUT-04, SCOPE-01, SCOPE-02
+**Success Criteria** (what must be TRUE):
+  1. 用户运行 `kb-workflow process <bilibili-url>` 后生成 Markdown 文件而非深度分析报告
+  2. Markdown 文件包含视频元数据（标题、作者、时长）
+  3. 元数据处理功能保持不变（BilibiliAdapter 正常工作）
+  4. 视频标签继续正常生成
+  5. 字幕文本已去除时间戳，按语义分段
+  6. 明显的语音识别错误已被 LLM 纠正
+  7. DeepAnalyzer 相关代码已移除或禁用
+  8. 知乎等其他平台处理器不受影响
+**Plans**: 2 plans (pending)
+
+Plans:
+- [ ] 12-01-PLAN.md — SRT 处理器实现（解析、去时间戳、分段、纠正）
+- [ ] 12-02-PLAN.md — 集成与测试，移除 DeepAnalyzer
