+See: .planning/PROJECT.md (updated 2026-03-21)
 
 **Core value:** 可靠、可维护的处理管道 - 每个步骤独立、可验证、可恢复
-**Current focus:** Phase 12 - SRT 简化处理器 (完成)
+**Current focus:** 语义分段改进 — 使用 LLM 实现智能分段

 ### Decisions
 
-Key decisions from v1.0-v1.4 (preserved):
+Key decisions from v1.0-v1.5 (preserved):
 - 管道模型 — BaseProcessor + Pipeline 架构
 - 步骤级状态 — WorkflowStateManager
 - Schema 验证 — Pydantic v2
 - 顺序执行 — 简单性和可调试性
 - CLI subparsers — 可扩展命令结构
+- SRT 独立模块 — kb_workflow/srt/ 职责分离
+- ASR 纠错可选 — AI 不可用时返回原文
 
-v1.5 scope:
-- 仅针对 B 站视频处理
-- 简化流程：SRT → 去时间戳 → 分段 → 纠正 → Markdown
-- 移除深度观点分析
-
-v1.5 Phase 12 decisions:
-- TDD approach with RED-GREEN cycles for all modules
-- Lazy import for ASRCorrector to avoid dependency issues
-- Simple rule-based segmentation (no LLM) for speed
-- ASR correction is optional, fallback to original text
-- B站视频使用 SRTProcessor，其他平台保持 AnalyzeProcessor
-- Pipeline 平台路由：检测 platform=bilibili + content_type=video
+v1.6 scope (待验证):
+- LLM 语义分析 — 替代简单规则分段
+- 通用自适应 — 自动识别视频类型
+- 主题识别与标题 — 主题章节生成标题
+- 内容完整性 — 避免错误截断话题
