## Accumulated Context
### Decisions
Key decisions from v1.0 (preserved):
Key decisions from v1.0-v1.4 (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
v1.3 decisions:
- 代理池使用索引指针实现 Round-Robin,惰性检查冷却恢复
- ProxyPool 参数优先于 config.proxy 配置
v1.4 scope:
- 只针对知乎反爬检测
- 使用最小改动(指纹伪装)先验证效果
- 行为伪装(鼠标轨迹等)暂不实现,如需要再加
v1.4 Phase 11 decisions:
- 使用 playwright-stealth 库进行指纹伪装
- Pydantic BaseModel 配置模型
- 分离 sync/async 函数匹配 Playwright API 模式
- stealth_config=None 表示默认启用 stealth (向后兼容)
- launch 时添加 --disable-blink-features=AutomationControlled 参数
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
