 ## 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

-v1.1 decisions:
- 中间目录统一到 `~/work/intermediate/analysis/`
- 归档只保留 md 文件，不归档 json 文件
- 最终目录按平台分组，不再按时间创建子目录
+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

-v1.2 decisions:
- 知乎登录策略：二维码扫码 + 手动 Cookie 降级
- 参考 MediaCrawler 实现，自实现而非直接依赖
- 使用 playwright 作为浏览器自动化框架
- 整合进现有 Pipeline 架构
- Cookie 文件权限设置为 600 保证安全性
- 保存 Cookie 后清除 get_settings 缓存确保配置刷新
- 使用 tenacity Retrying 对象而非 @retry 装饰器支持可配置超时
- 多个 canvas 选择器降级提高 QR 码检测鲁棒性
- login CLI 命令支持三种模式：扫码登录、导入 Cookie、状态检查
- Use Playwright request API for direct comment API calls instead of route interception
- Only fetch first-level comments (no nested replies)
- Use hot sorting (order=hot) for popular comments
- ZhihuAdapter uses ZhihuCrawler with comment crawling enabled by default
- Cookie expiration triggers automatic QR code login flow
- Comments appended to content in Markdown format with '## 热门评论' section
-
-v1.3 decisions:
- Phase 10-14 覆盖 17 个需求：代理池、行为伪装、验证码检测、错误恢复、平台适配
- 每个阶段 2-3 个计划，总计 11 个计划
- 代理池使用索引指针实现 Round-Robin，惰性检查冷却恢复
- 所有代理失效时回退到第一个代理继续尝试
- [Phase 10-proxy-pool]: ProxyPool parameter takes priority over config.proxy when both are provided
- [Phase 10-proxy-pool]: Health feedback methods added to ZhihuCrawler for future automatic proxy switching
+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

+# Semantic Segmentation for SRT Processing
+
+**Status:** Backlog
+**Priority:** Medium
+**Source:** User feedback during v1.5 testing
+
+## Problem
+
+Current `SemanticSegmenter` uses simple heuristic rules:
+- Time gap > 3 seconds
+- Paragraph length > 500 characters
+
+This approach cannot identify **semantic topic transitions**.
+
+### Example Case
+
+Video: BV1MiPSz2ErY (科学透镜 - 5 topics in one video)
+1. 银河系中心的超大黑洞人马座A*其实不是黑洞
+2. 银河系和仙女座星系等构成的本星系群陷入巨大物质薄片
+3. 科学家为世界上97%的建筑生成3D模型
+4. 雷暴的形成
+5. 闪电的形成
+
+Current segmentation mixes these topics together.
+
+## Potential Solutions
+
+### Option 1: Transition Keyword Detection (Simple)
+- Detect common transition phrases: "接下来", "另外", "第二个", etc.
+- **Pros:** Fast, no API calls
+- **Cons:** Low accuracy, many videos lack explicit transitions
+
+### Option 2: LLM-Based Segmentation (Accurate)
+- Ask LLM to analyze entire subtitle and identify topic boundaries
+- **Pros:** Highest accuracy, understands semantics
+- **Cons:** Extra API cost, token limits for long videos
+
+### Option 3: Two-Stage Approach (Balanced)
+- Stage 1: Simple rule-based segmentation (current)
+- Stage 2: LLM checks paragraph beginnings for new topics
+- **Pros:** Most cases use simple rules, LLM only for key decisions
+- **Cons:** More complex implementation
+
+### Option 4: Embedding-Based Similarity
+- Calculate semantic similarity between adjacent paragraphs
+- Low similarity = topic boundary
+- **Pros:** No LLM API calls, runs locally
+- **Cons:** Requires embedding model, implementation complexity
+
+## Recommendation
+
+**Phase 1 (Quick Win):** Transition keyword detection + improve prompt
+
+**Phase 2 (Full Solution):** Two-stage approach with optional LLM semantic segmentation
+
+## Success Criteria
+
+1. Topics are separated correctly
+2. Each paragraph covers a single coherent topic
+3. No false splits within a topic

+  修复2: SRTProcessor metadata 扁平化
+  - 文件：kb_workflow/pipeline/processors/srt.py (第162-195行)
+  - 修改：添加扁平化逻辑，处理嵌套结构 {metadata: {...}}
+  - 效果：正确提取 title/author 等元数据字段
+
+  修复3: 移除 SRTProcessor 摘要部分
+  - 文件：kb_workflow/pipeline/processors/srt.py (第195-230行)
+  - 修改：移除摘要部分生成代码
+  - 效果：不再生成低质量的摘要部分
+
+  修复4: duration 字段类型处理
+  - 文件：kb_workflow/pipeline/processors/srt.py (第276-284行)
+  - 修改：添加类型检查，支持字符串和整数格式
+  - 效果：正确处理 "05:42" 字符串格式的时长
+

+  - ✅ metadata 扁平化逻辑正确
+  - ✅ frontmatter 生成正确（title, author, bvid 都正确）
+  - ✅ duration 字段类型处理正确
+
+  等待端到端测试：
+  1. 重新运行 Bilibili pipeline 处理 BV1MiPSz2ErY
+  2. 检查生成的 analysis.md 文件
+expecting: |
+  1. ASR纠错准确性提高（"银河系"不应被误写为"鲜合器"）
+  2. 输出不再包含摘要部分

+  4. 元数据正确显示作者："科学透镜"
+next_action: |
+  等待用户重新运行 pipeline 并验证结果
+
+## Symptoms
+expected: |
+  1. ASR纠错准确（如"银河系"不会被误写为"鲜合器"）
+  2. 摘要是真正的总结提炼，不是重复开头文字（或直接移除摘要部分）
+  3. 元数据正确显示标题、作者等
+actual: |
+  1. 第18行显示"我们的鲜合器其实是被吸引进了一个明天数千万光年..." - 识别错误
+  2. 第8-10行摘要只是重复视频开头文字，非真正总结

+## Resolution
+
+root_cause: |
+  1. **thinking.type=disabled 导致ASR纠错准确性下降**
+     - SimpleAIClient._call_zhipu() 禁用思考模式
+     - 影响 ASRCorrector 纠错质量
+
+  2. **SRTProcessor 未扁平化嵌套 metadata 结构**
+     - metadata.json: {metadata: {title: "xxx", author: "xxx"}}
+     - SRTProcessor._generate_frontmatter() 直接访问 metadata.get('title')
+     - 返回 None，使用默认值"未命名"
+
+  3. **SRTProcessor 自动生成低质量摘要**
+     - 第219-226行简单复制第一段开头200字符
+     - 用户要求移除摘要部分
+
+  4. **duration 字段类型处理不当**
+     - metadata 中 duration 是字符串 "05:42"
+     - _format_duration 期望整数秒数
+     - 导致 TypeError
+
+fix: |
+  1. **kb_workflow/deep_analyzer/__init__.py (第91-122行)**
+     - 修改 _call_zhipu() 方法
+     - 移除 `"thinking": {"type": "disabled"}` 参数
+     - 让AI使用默认思考模式以提高准确性
+     - 同时处理 reasoning_content 字段作为后备
+
+  2. **kb_workflow/pipeline/processors/srt.py (第162-195行)**
+     - 修改 _load_metadata() 方法
+     - 添加扁平化逻辑，与 AnalyzeProcessor._normalize_metadata() 一致
+     - 处理嵌套结构 {metadata: {...}}
+

+created: 2026-03-21T22:00:00.000000
+updated: 2026-03-21T22:30:00.000000
+---
+
+## Current Focus
+hypothesis: 修复已完成并通过测试
+test: 所有自动化测试通过（4/4）
+expecting: ASR 纠错将使用禁用思考模式，文件命名将包含标题
+next_action: 用户需要在实际环境中验证修复效果
+
+## 自我验证结果
+- ✓ SimpleAIClient 支持 disable_reasoning 参数
+- ✓ ASRCorrector 使用 disable_reasoning=True
+- ✓ ArchiveProcessor 从 frontmatter 提取标题
+- ✓ _call_zhipu 在 disable_reasoning=True 时添加 thinking.type=disabled
+
+## Symptoms
+expected: |
+  1. ASR 纠错后输出纠正和润色后的完整字幕内容
+  2. 文件命名包含视频标题
+actual: |
+  1. 输出包含 AI 的思考过程（Analyze the Request, 分析请求等）
+  2. 文件命名格式：20260321_BV1MiPSz2ErY_analysis.md（缺少标题）
+errors: |
+  - AI 返回 reasoning_content 而非 content
+  - 文件命名未包含标题
+reproduction: |
+  参考：~/work/zq/30.资源/AI分析/bilibili/20260321_BV1MiPSz2ErY_analysis.md
+  文件内容显示AI的思考分析过程而非纠错后的字幕
+started: |
+  2026-03-21，修复 DeepAnalyzer 后重新启用思考模式，但 SRTProcessor 也受到相同问题影响
+
+## Eliminated
+
+## Evidence
+- timestamp: 2026-03-21T22:00:00
+  checked: 实际输出文件 ~/work/zq/30.资源/AI分析/bilibili/20260321_BV1MiPSz2ErY_analysis.md
+  found: 文件内容包含 AI 的思考分析过程（"Analyze the Request", "分析请求" 等），而非纠错后的字幕
+  implication: 修复代码没有生效，问题仍然存在
+
+- timestamp: 2026-03-21T22:00:00
+  checked: DeepAnalyzer._call_zhipu 的修复逻辑（第 110-124 行）
+  found: 代码逻辑是"优先返回 content 字段，如果 content 为空才使用 reasoning_content"
+  implication: 这个逻辑是错误的！当启用思考模式时，content 不为空但包含的是 AI 的分析过程
+
+- timestamp: 2026-03-21T22:00:00
+  checked: 智谱 API 文档
+  found: thinking.type 参数控制是否启用思考模式：enabled（默认）或 disabled
+  implication: 解决方案是在调用 API 时显式设置 thinking.type="disabled" 来禁用思考模式
+
+- timestamp: 2026-03-21T22:00:00
+  checked: 提交 7ac4937 的 diff
+  found: 该提交移除了 thinking.type="disabled" 参数，导致启用默认的思考模式
+  implication: 这就是问题的根源！移除 thinking.type="disabled" 后，AI 返回分析过程而非直接答案
+
+- timestamp: 2026-03-21T22:00:00
+  checked: 之前的提交 7903690
+  found: 这个提交添加了 thinking.type="disabled" 参数来禁用思考模式
+  implication: 但提交 7ac4937 又移除了它，导致问题重新出现
+
+## Resolution
+root_cause: |
+  提交 7ac4937 移除了 thinking.type="disabled" 参数，导致智谱 API 使用默认的思考模式。
+  当启用思考模式时，AI 返回的内容（content 字段）包含了详细的分析过程（如 "Analyze the Request"），
+  而非我们期望的直接纠错后的字幕。ASR 纠错需要的是直接结果，不需要分析过程。
+
+fix: |
+  1. 在 SimpleAIClient 中添加 disable_reasoning 参数（默认 False）
+  2. 在 ASRCorrector 调用时设置 disable_reasoning=True
+  3. 在 _call_zhipu 方法中，当 disable_reasoning=True 时添加 thinking.type="disabled" 参数
+  4. 在 ArchiveProcessor 中从 frontmatter 提取标题并添加到文件名
+files_changed: []
+  - kb_workflow/deep_analyzer/__init__.py: 添加 disable_reasoning 参数支持
+  - kb_workflow/srt/corrector.py: ASRCorrector 使用 disable_reasoning=True
+  - kb_workflow/pipeline/processors/archive.py: 从文件提取标题并添加到文件名
+
+verification: |
+  自动化测试全部通过（4/4）：
+
+  1. ✓ SimpleAIClient 默认 disable_reasoning=False
+  2. ✓ 可以设置 disable_reasoning=True
+  3. ✓ generate 方法有 disable_reasoning 参数
+  4. ✓ ASRCorrector._correct_batch 使用 disable_reasoning=True
+  5. ✓ _extract_title_from_file 正确提取标题
+  6. ✓ _sanitize_title 清理标题
+  7. ✓ _call_zhipu 在 disable_reasoning=True 时添加 thinking.type=disabled
+  8. ✓ _call_zhipu 返回 content 字段

+# Phase 11 Plan 01: Stealth Fingerprint Masking Summary
+
+**Created stealth module using playwright-stealth library with StealthConfig Pydantic model, sync/async apply functions, and 9 passing unit tests**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-03-18T15:45:09Z
+- **Completed:** 2026-03-18T15:47:58Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+- StealthConfig Pydantic model with 17 evasion options (navigator, chrome, webgl, etc.)
+- apply_stealth_sync and apply_stealth_async functions for browser context masking
+- 9 unit tests covering config defaults, stealth application, and disabled mode
+- All 74 crawler tests pass (no regression)
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1 + Task 2: Stealth module and tests (TDD)** - `e152b8e` (feat)
+
+_Note: TDD flow combined test and implementation in single commit_
+
+## Files Created/Modified
+- `kb_workflow/crawler/stealth/__init__.py` - Module entry point, exports StealthConfig and apply functions
+- `kb_workflow/crawler/stealth/stealth_config.py` - StealthConfig model and apply_stealth_sync/async functions
+- `tests/test_crawler/test_stealth.py` - 9 unit tests for stealth module
+- `tests/test_crawler/conftest.py` - Added stealth_config and mock_browser_context fixtures
+
+## Decisions Made
+- Use playwright-stealth library (external dependency) for fingerprint masking - proven solution with active maintenance
+- Pydantic BaseModel for configuration - provides validation, IDE support, and easy serialization
+- Separate sync/async functions to match Playwright's API patterns
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed apply_stealth_sync calling wrong method**
+- **Found during:** Task 2 (test execution)
+- **Issue:** apply_stealth_sync was calling stealth.apply_stealth_async instead of stealth.apply_stealth_sync
+- **Fix:** Changed to call the correct sync method
+- **Files modified:** kb_workflow/crawler/stealth/stealth_config.py
+- **Verification:** All 9 tests pass
+- **Committed in:** e152b8e (Task commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 bug)
+**Impact on plan:** Minor fix necessary for correctness. No scope creep.
+
+## Issues Encountered
+None - TDD flow worked smoothly with RED -> GREEN -> verification
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Stealth module ready for integration into ZhihuCrawler
+- Next plan (11-02) will integrate stealth into ZhihuCrawler._start_browser_with_proxy()
+
+## Self-Check: PASSED
+- All 4 created files verified
+- Commit e152b8e verified in git log
+- All 9 tests pass
+- No regression in existing tests (74 total)

+
+**Integrated stealth fingerprint masking into ZhihuCrawler with backward-compatible stealth_config parameter**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-03-18T15:51:22Z
+- **Completed:** 2026-03-18T15:53:52Z
+- **Tasks:** 3
+- **Files modified:** 2
+
+## Accomplishments
+
+- ZhihuCrawler now applies stealth fingerprint masking automatically when starting browser
+- Added `--disable-blink-features=AutomationControlled` launch argument
+- Added `stealth_config` parameter for explicit control (default None = enabled)
+- 8 new integration tests covering stealth behavior and backward compatibility
+- All 82 crawler tests pass (no regressions)
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1-2: TDD Integration** - `56c21f3` (test) + `08cbe24` (feat)
+2. **Task 3: Regression Test** - No changes needed (all 82 tests pass)
+
+**Plan metadata:** (pending)
+
+## Files Created/Modified
+
+- `kb_workflow/crawler/zhihu_crawler.py` - Added stealth_config parameter, stealth import, launch args, apply_stealth_sync call
+- `tests/test_crawler/test_zhihu_crawler_stealth.py` - 8 new integration tests (created)
+
+## Decisions Made
+
+- **stealth_config=None means enabled by default**: Maintains backward compatibility - existing code gets stealth protection without changes
+- **Launch arg added only when stealth enabled**: Avoids unnecessary flags when explicitly disabled
+- **apply_stealth_sync called after context creation**: Matches stealth library requirements
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness

+# Phase 11: Stealth Fingerprinting - Research
+
+**Researched:** 2026-03-18
+**Domain:** Playwright 指纹伪装、反检测技术
+**Confidence:** HIGH
+
+## Summary
+
+知乎使用浏览器指纹检测来识别 Playwright 自动化脚本，触发 40362 错误。核心检测点包括 `navigator.webdriver` 属性、Playwright 特有的 JS 属性（`__playwright`、`pwInspect` 等）、以及 Chrome 对象的完整性。
+
+**Primary recommendation:** 使用已安装的 `playwright-stealth` 库（v2.0.2）配合自定义 init script，在 ZhihuCrawler 启动浏览器时注入伪装脚本。
+
+## Standard Stack
+
+### Core
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| playwright-stealth | 2.0.2 | 指纹伪装核心库 | 已安装，提供 18 种 evasion scripts，从 puppeteer-extra-plugin-stealth 移植 |
+| playwright | (existing) | 浏览器自动化 | 项目已使用 |
+
+### Supporting
+| Library | Version | Purpose | When to Use |
+|---------|---------|---------|-------------|
+| tenacity | (existing) | 重试机制 | 已在 ZhihuCrawler 中使用 |
+
+### Alternatives Considered
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| playwright-stealth | 手写 init script | 库更全面，维护更好；手写适合特定场景 |
+| playwright-stealth | Camoufox (Firefox) | Camoufox 更隐蔽但需要切换浏览器引擎，改动大 |
+| playwright-stealth | Nodriver | Nodriver 是 async Chrome，需要重构代码 |
+
+**Installation:**
+```bash
+# 已安装
+pip install playwright-stealth  # v2.0.2
+```
+
+## Architecture Patterns
+
+### Recommended Project Structure
+```
+kb_workflow/crawler/
+├── zhihu_crawler.py      # 现有爬虫（需集成 stealth）
+├── stealth/               # 新增：指纹伪装模块
+│   ├── __init__.py
+│   └── stealth_config.py  # Stealth 配置
+├── config.py              # 现有配置
+├── proxy_pool.py          # 现有代理池
+└── models.py              # 现有数据模型
+```
+
+### Pattern 1: Stealth 集成模式
+
+**What:** 在 `_start_browser_with_proxy()` 方法中，创建 context 后立即应用 stealth
+
+**When to use:** 所有需要访问知乎的场景
+
+**Example:**
+```python
+# Source: playwright-stealth 官方 + 项目现有代码
+from playwright.sync_api import sync_playwright
+from playwright_stealth import Stealth
+
+def _start_browser_with_proxy(self, cookie: str) -> None:
+    """Start browser with proxy configuration and stealth."""
+    self._playwright = sync_playwright().start()
+    self._browser = self._playwright.chromium.launch(
+        headless=self.headless,
+        # 关键：禁用 AutomationControlled 特征
+        args=['--disable-blink-features=AutomationControlled']
+    )
+
+    context_options = {
+        'user_agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) ...',
+        'service_workers': 'block'  # 现有配置
+    }
+    # ... 代理配置 ...
+
+    self._context = self._browser.new_context(**context_options)
+
+    # 关键：应用 stealth
+    stealth = Stealth(
+        navigator_webdriver=True,
+        navigator_user_agent=True,
+        navigator_plugins=True,
+        navigator_languages=True,
+        webgl_vendor=True,
+        chrome_app=True,
+        chrome_csi=True,
+        chrome_load_times=True,
+    )
+    stealth.apply_stealth_sync(self._context)
+
+    # 后续代码不变
+    if cookie:
+        self._add_cookies(cookie)
+    self._page = self._context.new_page()
+```
+
+### Pattern 2: 最小化 Init Script（备选）
+
+**What:** 如果不想引入 playwright-stealth，可使用最小化脚本
+
+**When to use:** 只需隐藏 webdriver 属性的简单场景
+
+**Example:**
+```python
+# Source: Stack Overflow https://stackoverflow.com/questions/75754759
+STEALTH_SCRIPT = """
+// 隐藏 navigator.webdriver
+Object.defineProperty(navigator, 'webdriver', {
+    get: () => undefined
+});
+
+// 移除 Playwright 特有属性
+delete window.__playwright;
+delete window.__pw_manual;
+delete window.__PW_inspect;
+
+// 模拟 Chrome 对象
+window.chrome = {
+    runtime: {},
+    loadTimes: function() {},
+    csi: function() {},
+    app: {}
+};
+"""
+
+# 在 context 创建后注入
+self._context.add_init_script(STEALTH_SCRIPT)
+```
+
+### Anti-Patterns to Avoid
+
+- **Anti-pattern 1: 只修改 webdriver 属性**
+  - 为什么不好：现代检测会检查 Chrome 对象完整性、plugins 数组、WebGL vendor 等
+  - 应该：使用 playwright-stealth 的完整 evasion 套件
+
+- **Anti-pattern 2: 在 page.goto() 后注入脚本**
+  - 为什么不好：页面加载时检测脚本已经执行，太晚了
+  - 应该：使用 `context.add_init_script()` 或 `page.add_init_script()` 在页面加载前注入
+
+- **Anti-pattern 3: 忽略 Chrome 启动参数**
+  - 为什么不好：`--disable-blink-features=AutomationControlled` 是第一层防护
+  - 应该：同时使用 CLI 参数和 init script
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| navigator.webdriver 伪装 | 手写 Object.defineProperty | playwright-stealth | 库使用 Proxy 更隐蔽，绕过 descriptor 检测 |
+| Chrome 对象模拟 | 自己拼凑 chrome.runtime 等 | playwright-stealth | 需要模拟 loadTimes、csi 等复杂结构 |
+| Plugins 数组伪装 | 手动创建 navigator.plugins | playwright-stealth | 需要生成符合浏览器特征的 MIME types |
+| WebGL 指纹 | 修改 getParameter 返回值 | playwright-stealth | 需要模拟真实的 renderer/vendor 字符串 |
+
+**Key insight:** playwright-stealth 包含 18 个 evasion scripts，覆盖 Chrome 环境的各个方面。自己实现容易遗漏检测点，且需要持续维护对抗新检测手段。
+
+## Common Pitfalls
+
+### Pitfall 1: 40362 错误仍出现
+
+**What goes wrong:** 集成 stealth 后仍被知乎检测到
+
+**Why it happens:**
+1. 没有同时使用 CLI 参数 `--disable-blink-features=AutomationControlled`
+2. 只隐藏了 webdriver 但 Chrome 对象不完整
+3. 浏览器缓存了被污染的 profile
+
+**How to avoid:**
+1. 确保 `browser.launch(args=['--disable-blink-features=AutomationControlled'])`
+2. 使用完整的 stealth 配置，不只是 navigator_webdriver
+3. 清除 Chrome 缓存：`rm -rf ~/.cache/chrome-*`（参考 GitHub js-reverse-mcp 项目）
+
+**Warning signs:** 页面加载后控制台出现 `navigator.webdriver === true`
+
+### Pitfall 2: Headless 模式更容易被检测
+
+**What goes wrong:** headless=True 时被检测，headless=False 正常
+
+**Why it happens:** Headless Chrome 有额外的指纹特征（User-Agent 中的 HeadlessChrome 字符串）
+
+**How to avoid:**
+1. playwright-stealth 会自动将 HeadlessChrome 替换为 Chrome
+2. 确保 `navigator_user_agent=True` 选项开启
+
+**Warning signs:** User-Agent 包含 "HeadlessChrome"
+
+### Pitfall 3: Service Worker 干扰 API 拦截
+
+**What goes wrong:** 现有代码已使用 `service_workers: "block"`，与 stealth 无冲突
+
+**Why it happens:** 这是正确做法，继续保持
+
+**How to avoid:** 无需额外处理，现有配置已正确
+
+**Warning signs:** API 拦截不生效
+
+## Code Examples
+
+### 示例 1: ZhihuCrawler 集成 Stealth
+
+```python
+# Source: 项目代码改编
+# kb_workflow/crawler/zhihu_crawler.py
+
+from playwright_stealth import Stealth
+
+class ZhihuCrawler:
+    def __init__(
+        self,
+        headless: bool = True,
+        timeout: int = 30,
+        config: Optional[CrawlerConfig] = None,
+        proxy_pool: Optional[ProxyPool] = None,
+        stealth_enabled: bool = True  # 新增参数
+    ):
+        # ... 现有初始化代码 ...
+        self.stealth_enabled = stealth_enabled
+        self._stealth: Optional[Stealth] = None
+
+    def _start_browser_with_proxy(self, cookie: str) -> None:
+        """Start browser with proxy configuration."""
+        self.config.validate_proxy()
+
+        # 关键改动：添加 --disable-blink-features 参数
+        launch_args = []
+        if self.stealth_enabled:
+            launch_args.append('--disable-blink-features=AutomationControlled')
+
+        self._playwright = sync_playwright().start()
+        self._browser = self._playwright.chromium.launch(
+            headless=self.headless,
+            args=launch_args if launch_args else None
+        )
+
+        context_options = {
+            'user_agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36'
+        }
+        # ... 代理配置逻辑不变 ...
+
+        context_options["service_workers"] = "block"
+        self._context = self._browser.new_context(**context_options)
+
+        # 关键改动：应用 stealth
+        if self.stealth_enabled:
+            self._stealth = Stealth(
+                navigator_webdriver=True,
+                navigator_user_agent=True,
+                navigator_plugins=True,
+                navigator_languages=True,
+                navigator_platform=True,
+                navigator_vendor=True,
+                webgl_vendor=True,
+                chrome_app=True,
+                chrome_csi=True,
+                chrome_load_times=True,
+                hairline=True,
+                iframe_content_window=True,
+                media_codecs=True,
+                navigator_permissions=True,
+                error_prototype=True,
+                sec_ch_ua=True,
+            )
+            self._stealth.apply_stealth_sync(self._context)
+
+        if cookie:
+            self._add_cookies(cookie)
+
+        self._page = self._context.new_page()
+        self._page.set_default_timeout(self.timeout * 1000)
+```
+
+### 示例 2: 验证 Stealth 是否生效
+
+```python
+# Source: 测试用例
+def verify_stealth_applied(page) -> dict:
+    """验证 stealth 脚本是否正确应用"""
+    checks = {}
+
+    # 检查 navigator.webdriver
+    checks['webdriver'] = page.evaluate('navigator.webdriver')
+    # 期望值: false 或 undefined
+
+    # 检查 Chrome 对象
+    checks['chrome_exists'] = page.evaluate('typeof window.chrome !== "undefined"')
+    # 期望值: true
+
+    # 检查 Playwright 特有属性
+    checks['playwright_removed'] = page.evaluate(
+        'typeof window.__playwright === "undefined"'
+    )
+    # 期望值: true
+
+    # 检查 plugins 数组
+    checks['plugins_count'] = page.evaluate('navigator.plugins.length')
+    # 期望值: > 0
+
+    return checks
+```
+
+### 示例 3: playwright-stealth 同步 API
+
+```python
+# Source: playwright-stealth 官方文档
+from playwright.sync_api import sync_playwright
+from playwright_stealth import Stealth
+
+with sync_playwright() as p:
+    browser = p.chromium.launch(headless=True)
+    page = browser.new_page()
+
+    # 方式 1: 使用 Stealth 类（推荐，可配置）
+    stealth = Stealth(navigator_webdriver=True)
+    stealth.apply_stealth_sync(page)
+
+    # 方式 2: 使用 use_sync 上下文管理器
+    # with stealth.use_sync(sync_playwright()) as p:
+    #     browser = p.chromium.launch()
+    #     page = browser.new_page()
+    #     # 自动应用 stealth
+
+    page.goto('https://www.zhihu.com/')
+    browser.close()
+```
+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Object.defineProperty 直接覆盖 | Proxy 包装 getter | 2024+ | 绕过 descriptor 检测 |
+| 单独隐藏 webdriver | 18+ evasion scripts | 2023+ | 全面指纹伪装 |
+| 手动 User-Agent 替换 | 自动替换 HeadlessChrome | playwright-stealth 2.0 | 更可靠 |
+
+**Deprecated/outdated:**
+- `navigator.webdriver = undefined` 直接赋值：现代浏览器属性是只读的，必须用 Proxy
+- 只处理 webdriver：知乎检测多维度指纹，单一隐藏无效
+
+## Open Questions
+
+1. **知乎是否使用 TLS 指纹检测？**
+   - What we know: 40362 错误主要与 JS 指纹相关
+   - What's unclear: 是否有服务端 TLS 握手分析
+   - Recommendation: 先用 JS 指纹伪装验证，如仍有问题再考虑 TLS
+
+2. **playwright-stealth 与代理池的交互？**
+   - What we know: 两者独立工作，无直接依赖
+   - What's unclear: 代理 IP 变更后是否需要重新应用 stealth
+   - Recommendation: 不需要，stealth 只影响 JS 环境

+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+| ---- | ---- | ------- | -------- | ------ |
+| None | - | - | - | No anti-patterns detected |
+
+No TODO/FIXME/placeholder comments found in stealth module or zhihu_crawler.py.
+
+### Human Verification Required
+
+The following items require human testing to fully confirm goal achievement:
+
+#### 1. Real Zhihu Access Test
+
+**Test:** Configure ZhihuCrawler with stealth enabled and crawl a real Zhihu answer page
+**Expected:** No 40362 error, content successfully captured
+**Why human:** Real-world anti-crawler detection requires live testing against production servers
+
+#### 2. Browser Fingerprint Inspection
+
+**Test:** Launch browser with stealth, open DevTools console, evaluate `navigator.webdriver`
+**Expected:** Returns `undefined` or `false`, not `true`
+**Why human:** Requires launching actual browser and manually inspecting JavaScript properties
+
+#### 3. Playwright Properties Check
+
+**Test:** In same browser, check for `window.__playwright`, `window.__pw_manual`, etc.
+**Expected:** All return `undefined`
+**Why human:** Requires manual browser inspection
+
+### Gaps Summary

+# Phase 12 Plan 01: SRT Processing Module Summary
+
+## One-liner
+
+创建 SRT 字幕处理模块，实现字幕解析、语义分段和 LLM 纠错功能，将 B站字幕转换为易读的 Markdown 文档。
+
+## Implementation Details
+
+### Task 1: SRT Parser Module
+
+**Files:** `kb_workflow/srt/__init__.py`, `kb_workflow/srt/parser.py`, `tests/test_srt_processor.py`
+
+- Created `Segment` dataclass for subtitle segments
+- Implemented `parse_srt()` function to parse SRT content string
+- Implemented `parse_srt_file()` function to parse from file path
+- Used regex pattern to match SRT blocks
+- Handled special characters and multi-line subtitles
+
+**Key Code:**
+```python
+@dataclass
+class Segment:
+    id: int
+    start_time: float
+    end_time: float
+    text: str
+
+def parse_srt(content: str) -> List[Segment]:
+    # Parse SRT format using regex
+    # Convert timestamps to seconds
+    # Return list of Segment objects
+```
+
+### Task 2: Semantic Segmenter
+
+**Files:** `kb_workflow/srt/segmenter.py`, `tests/test_srt_processor.py`
+
+- Created `SemanticSegmenter` class for paragraph segmentation
+- Implemented time-gap based splitting (>3 seconds)
+- Added max paragraph length constraint (500 chars)
+- Simple rule-based approach (no LLM needed)
+
+**Key Code:**
+```python
+class SemanticSegmenter:
+    def __init__(self, gap_threshold=3.0, max_paragraph_chars=500):
+        ...
+
+    def segment(self, segments: List[Segment]) -> List[str]:
+        # Split on time gaps
+        # Enforce paragraph length limits
+        # Return list of paragraph strings
+```
+
+### Task 3: ASR Corrector
+
+**Files:** `kb_workflow/srt/corrector.py`, `tests/test_srt_processor.py`
+
+- Created `ASRCorrector` class for speech recognition error correction
+- Reuses `SimpleAIClient` from deep_analyzer
+- Implemented batch processing for long text (5000 chars per batch)
+- Fallback to original text when AI unavailable
+
+**Key Code:**
+```python
+class ASRCorrector:
+    def __init__(self, ai_client=None, batch_size=5000):
+        ...
+
+    def correct(self, text: str) -> str:
+        # Use LLM to correct obvious errors
+        # Batch process long text
+        # Return corrected text or original
+```
+
+### Task 4: SRTProcessor and Markdown Generation
+
+**Files:** `kb_workflow/pipeline/processors/srt.py`, `kb_workflow/pipeline/schemas.py`, `tests/test_srt_processor.py`
+
+- Created `SRTProcessor` following BaseProcessor pattern
+- Added `SRTInput` and `SRTOutput` schemas
+- Generated Markdown with YAML frontmatter
+- Handled missing metadata gracefully
+
+**Key Code:**
+```python
+class SRTProcessor(BaseProcessor):
+    STEP_NAME = "srt"
+
+    async def process(self, input_data: SRTInput) -> SRTOutput:
+        # 1. Parse SRT file
+        # 2. Semantic segmentation
+        # 3. ASR correction (optional)
+        # 4. Generate Markdown
+```
+
+## Deviations from Plan
+
+None - plan executed exactly as written.

+    修改 Pipeline 支持平台特定处理流程:
+
+    1. 更新 `kb_workflow/pipeline/schemas.py`:
+       - 确认 `SRTInput` 和 `SRTOutput` 已在 12-01 中添加
+       - 添加 `SRTInput` 到 imports
+
+    2. 修改 `kb_workflow/pipeline/pipeline.py` 的 `run` 方法:
+       - 在 step 处理循环中，检测 B 站视频 + analyze 步骤的情况
+       - B 站视频（platform="bilibili", content_type="video"）时:
+         - 跳过 "analyze" 步骤
+         - 执行 "srt" 步骤（使用 SRTProcessor）
+       - 其他情况保持原有逻辑
+
+    3. 修改 `run` 方法中的步骤输入创建逻辑:
+       - 添加 `elif step_name == "srt":` 分支
+       - SRTInput 需要: srt_file（从 ASR 结果获取）, metadata_file, output_file
+
+    4. 修改 `_populate_skipped_step_results` 方法:
+       - 添加 "srt" 步骤的现有文件扫描逻辑
+
+    关键代码位置: pipeline.py 约 170-250 行

+       - 导入 SRTProcessor: `from .pipeline.processors import SRTProcessor`
+       - 将 SRTProcessor 添加到 processors 列表
+       - 更新 PipelineConfig.steps: `["parse", "download", "asr", "srt", "analyze", "archive"]`
+         （Pipeline 会根据平台条件跳过不需要的步骤）

+
+    1. 修改 `kb_workflow/deep_analyzer/__init__.py`:

+
+### 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**：
+
+1. **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
+2. **Pipeline 集成成功** - B站视频使用 SRTProcessor，其他平台保持 AnalyzeProcessor
+3. **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
+4. **DeepAnalyzer 弃用警告已添加** - 提醒开发者 B站视频应使用 SRTProcessor
+5. **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。
