+# 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)
