+# Phase 11 — Validation Strategy
+
+> Per-phase validation contract for feedback sampling during execution.
+
+---
+
+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **Framework** | pytest |
+| **Config file** | pytest.ini (pythonpath=., testpaths=tests) |
+| **Quick run command** | `pytest tests/test_crawler/ -x -v` |
+| **Full suite command** | `pytest tests/ -v` |
+| **Estimated runtime** | ~30 seconds |
+
+---
+
+## Sampling Rate
+
+- **After every task commit:** Run `pytest tests/test_crawler/ -x`
+- **After every plan wave:** Run `pytest tests/ -v`
+- **Before `/gsd:verify-work`:** Full suite must be green
+- **Max feedback latency:** 30 seconds
+
+---
+
+## Per-Task Verification Map
+
+| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
+|---------|------|------|-------------|-----------|-------------------|-------------|--------|
+| 11-01-01 | 01 | 1 | STEALTH-01 | unit | `pytest tests/test_crawler/test_stealth.py::test_navigator_webdriver_hidden -x` | ❌ W0 | ⬜ pending |
+| 11-01-02 | 01 | 1 | STEALTH-02 | unit | `pytest tests/test_crawler/test_stealth.py::test_playwright_properties_removed -x` | ❌ W0 | ⬜ pending |
+| 11-01-03 | 01 | 1 | STEALTH-03 | unit | `pytest tests/test_crawler/test_stealth.py::test_chrome_properties_mocked -x` | ❌ W0 | ⬜ pending |
+| 11-01-04 | 01 | 1 | STEALTH-04 | unit | `pytest tests/test_crawler/test_stealth.py::test_user_agent_modified -x` | ❌ W0 | ⬜ pending |
+| 11-02-01 | 02 | 1 | VERIFY-01 | integration | `pytest tests/test_crawler/test_zhihu_crawler_stealth.py::test_crawl_answer_with_stealth -x` | ❌ W0 | ⬜ pending |
+| 11-02-02 | 02 | 1 | VERIFY-02 | regression | `pytest tests/test_crawler/ -v` | ✅ Existing | ⬜ pending |
+
+*Status: ⬜ pending · ✅ green · ❌ red · ⚠️ flaky*

+
+## Wave 0 Requirements
+
+- [ ] `tests/test_crawler/test_stealth.py` — stubs for STEALTH-01, STEALTH-02, STEALTH-03, STEALTH-04
+- [ ] `tests/test_crawler/test_zhihu_crawler_stealth.py` — integration test for VERIFY-01
+- [ ] `tests/test_crawler/conftest.py` — add `stealth_config` fixture
+
+---
+
+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| 知乎 40362 错误消失 | VERIFY-01 | 需要真实网络环境 | 1. 运行 `python -m kb_workflow.crawler.zhihu_crawler` 访问问答页面 2. 确认无 40362 错误 |
+
+---
+
+## Validation Sign-Off
+
+- [ ] All tasks have `<automated>` verify or Wave 0 dependencies
+- [ ] Sampling continuity: no 3 consecutive tasks without automated verify
+- [ ] Wave 0 covers all MISSING references
+- [ ] No watch-mode flags
+- [ ] Feedback latency < 30s
+- [ ] `nyquist_compliant: true` set in frontmatter
+
+**Approval:** pending
