+# Phase 2 — Validation Strategy
+
+> Per-phase validation contract for feedback sampling during execution.
+
+---
+
+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **Framework** | pytest (existing from Phase 1) |
+| **Config file** | pyproject.toml |
+| **Quick run command** | `pytest tests/ -x -q` |
+| **Full suite command** | `pytest tests/ -v --cov=src/gsd_openclaw` |
+| **Estimated runtime** | ~15 seconds |
+
+---
+
+## Sampling Rate
+
+- **After every task commit:** Run `pytest tests/ -x -q`
+- **After every plan wave:** Run `pytest tests/ -v --cov=src/gsd_openclaw`
+- **Before `/gsd:verify-work`:** Full suite must be green
+- **Max feedback latency:** 15 seconds
+
+---
+

+
+## Wave 0 Requirements
+
+- [ ] `tests/test_skill_md.py` — tests for SKILL.md parsing and validation
+- [ ] `tests/test_response_formatter.py` — tests for Feishu card formatting
+- [ ] `tests/test_prompts.py` — tests for prompt template loading
+- [ ] `tests/fixtures/sample_outputs.py` — sample GSD outputs for testing
+
+*Existing infrastructure (conftest.py, pytest) covers framework requirements.*
+
+---
+
+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| Feishu card rendering | OCLW-04 | Requires live Feishu environment | Send test card via Feishu API, verify visual rendering |
+| Button callback routing | OCLW-02 | Requires OpenClaw integration | Click button in Feishu, verify callback received |
+
+---
+
+## 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
