Phase 11 Plan 02: Stealth Integration Summary

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

• ZhihuCrawler now has complete stealth fingerprint masking
• Ready for real-world testing against Zhihu anti-crawler measures
• Can be extended with behavior-based masking if fingerprint masking insufficient
