+# Phase 1 — Validation Strategy
+
+> Per-phase validation contract for feedback sampling during execution.
+
+---
+
+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **Framework** | pytest 7.x |
+| **Config file** | pyproject.toml (Wave 0 creates) |
+| **Quick run command** | `pytest tests/unit/ -q` |
+| **Full suite command** | `pytest tests/ -v --cov=src` |
+| **Estimated runtime** | ~15 seconds |
+
+---
+
+## Sampling Rate
+
+- **After every task commit:** Run `pytest tests/unit/ -q`
+- **After every plan wave:** Run `pytest tests/ -v --cov=src`
+- **Before `/gsd:verify-work`:** Full suite must be green
+- **Max feedback latency:** 15 seconds
+
+---
+
+## Per-Task Verification Map
+
+| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
+|---------|------|------|-------------|-----------|-------------------|-------------|--------|
+| 01-01-01 | 01 | 1 | PIPE-02, REL-01 | unit | `pytest tests/unit/test_state_manager.py -v` | ❌ W0 | ⬜ pending |
+| 01-01-02 | 01 | 1 | REL-02 | unit | `pytest tests/unit/test_state_manager.py::test_atomic_write -v` | ❌ W0 | ⬜ pending |
+| 01-02-01 | 02 | 1 | PIPE-03, VAL-01 | unit | `pytest tests/unit/test_schema_registry.py -v` | ❌ W0 | ⬜ pending |
+| 01-02-02 | 02 | 1 | PIPE-01 | unit | `pytest tests/unit/test_schema_registry.py::test_step_input_output -v` | ❌ W0 | ⬜ pending |
+| 01-03-01 | 03 | 1 | REL-03, MNT-03 | unit | `pytest tests/unit/test_error_handler.py -v` | ❌ W0 | ⬜ pending |
+| 01-03-02 | 03 | 1 | MNT-02 | unit | `pytest tests/unit/test_config_manager.py -v` | ❌ W0 | ⬜ pending |

+## Wave 0 Requirements
+
+- [ ] `tests/unit/test_state_manager.py` — stubs for PIPE-02, REL-01, REL-02
+- [ ] `tests/unit/test_schema_registry.py` — stubs for PIPE-01, PIPE-03, VAL-01
+- [ ] `tests/unit/test_error_handler.py` — stubs for REL-03, MNT-03
+- [ ] `tests/unit/test_config_manager.py` — stubs for MNT-02
+- [ ] `tests/conftest.py` — shared fixtures (temp dirs, mock env)
+- [ ] `pytest` + `pytest-cov` — if no framework detected
+
+---
+
+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| ~/.kb_env 验证失败时退出 | MNT-02 | 需要模拟真实环境 | 1. 移除必需变量 2. 运行 kb --help 3. 确认非零退出码和错误提示 |
+| 原子写入崩溃恢复 | REL-02 | 需要模拟进程终止 | 1. 在写入中途 kill 2. 检查 .bak 文件存在 3. 确认可恢复 |
+
+---
+
+## 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 < 15s
+- [ ] `nyquist_compliant: true` set in frontmatter

+**Approval:** pending
