+# Phase 08 — Validation Strategy
+
+> Per-phase validation contract for feedback sampling during execution.
+
+---
+
+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **Framework** | pytest 7.x |
+| **Config file** | pytest.ini |
+| **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 --tb=short`
+- **After every plan wave:** Run `pytest tests/ -v`
+- **Before `/gsd:verify-work`:** Full suite must be green
+- **Max feedback latency:** 30 seconds

+## Wave 0 Requirements
+
+- [ ] `tests/test_crawler/__init__.py` — 测试模块初始化
+- [ ] `tests/test_crawler/conftest.py` — 共享 fixtures (mock browser, mock API responses)
+- [ ] `tests/test_crawler/test_answer_crawler.py` — 问答爬取测试 stubs
+- [ ] `tests/test_crawler/test_article_crawler.py` — 专栏爬取测试 stubs
+- [ ] `tests/test_crawler/test_comment_crawler.py` — 评论爬取测试 stubs
+- [ ] `tests/test_crawler/test_metadata_extraction.py` — 元数据提取测试 stubs
+- [ ] `tests/test_crawler/test_proxy_config.py` — 代理配置测试 stubs
+- [ ] `tests/test_crawler/test_rate_limiter.py` — 频率控制测试 stubs
+- [ ] `tests/test_crawler/test_api_intercept.py` — API 拦截测试 stubs
+
+---
+
+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| 实际知乎页面爬取 | CONT-01, CONT-02 | 需要真实网络请求和 Cookie | 1. 配置代理 2. 运行 `kb crawl <url>` 3. 验证输出 JSON |
+| 代理实际生效 | NET-01 | 需要真实代理环境 | 1. 配置代理 2. 检查请求是否通过代理 |
+
+---
+
+## 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
