+# Phase 14 — Validation Strategy
+
+> Per-phase validation contract for feedback sampling during execution.
+
+---
+
+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **Framework** | pytest 7.x |
+| **Config file** | pytest.ini (已存在) |
+| **Quick run command** | `python3 -m pytest tests/test_semantic_robustness.py -v -x` |
+| **Full suite command** | `python3 -m pytest tests/ -v` |
+| **Estimated runtime** | ~5 seconds |
+
+---
+
+## Sampling Rate
+
+- **After every task commit:** Run `python3 -m pytest tests/test_semantic_robustness.py -v -x`
+- **After every plan wave:** Run `python3 -m pytest tests/ -v`
+- **Before `/gsd:verify-work`:** Full suite must be green
+- **Max feedback latency:** 10 seconds
+
+---
+
+## Per-Task Verification Map

+## Wave 0 Requirements
+
+- [ ] `tests/test_semantic_robustness.py` — 覆盖 ROBUST-01, ROBUST-02, ROBUST-03, ROBUST-04, COST-01, COST-02
+- [ ] `tests/test_srt_processor.py` — 覆盖 COST-03（配置开关）
+- [ ] `tests/conftest.py` — 共享 fixtures（mock LLM client, 样本字幕数据）
+- [ ] 框架安装: 无需安装，pytest 已配置
+
+**Mock Strategy:** 使用 unittest.mock.patch 模拟 SimpleAIClient.generate()，测试不同失败场景（网络错误、解析失败、超时等）
+
+---
+
+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| 无 | - | - | 所有阶段行为都有自动化验证 |
+
+---
+
+## 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 < 10s
+- [ ] `nyquist_compliant: true` set in frontmatter
+
+**Approval:** pending
