# 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/test_pipeline/ -q` |
| **Full suite command** | `pytest tests/ -v --cov=src` |
| **Estimated runtime** | ~15 seconds |

---

## Sampling Rate

- **After every task commit:** Run `pytest tests/test_pipeline/ -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/test_pipeline/test_state.py -v` | ❌ W0 | ⬜ pending |
| 01-01-02 | 01 | 1 | REL-02 | unit | `pytest tests/test_pipeline/test_state.py::test_atomic_write -v` | ❌ W0 | ⬜ pending |
| 01-02-01 | 02 | 1 | PIPE-03, VAL-01 | unit | `pytest tests/test_pipeline/test_schemas.py -v` | ❌ W0 | ⬜ pending |
| 01-02-02 | 02 | 1 | PIPE-01 | unit | `pytest tests/test_pipeline/test_schemas.py::test_step_input_output -v` | ❌ W0 | ⬜ pending |
| 01-03-01 | 03 | 1 | REL-03, MNT-03 | unit | `pytest tests/test_pipeline/test_errors.py -v` | ❌ W0 | ⬜ pending |
| 01-03-02 | 03 | 1 | MNT-02 | unit | `pytest tests/test_pipeline/test_config.py -v` | ❌ W0 | ⬜ pending |

*Status: ⬜ pending · ✅ green · ❌ red · ⚠️ flaky*

## Wave 0 Requirements

- [ ] `tests/test_pipeline/test_state.py` — stubs for PIPE-02, REL-01, REL-02
- [ ] `tests/test_pipeline/test_schemas.py` — stubs for PIPE-01, PIPE-03, VAL-01
- [ ] `tests/test_pipeline/test_errors.py` — stubs for REL-03, MNT-03
- [ ] `tests/test_pipeline/test_config.py` — stubs for MNT-02
- [ ] `tests/test_pipeline/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
