+# Phase 4 — Validation Strategy
+
+> Per-phase validation contract for feedback sampling during execution.
+
+---
+
+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **Framework** | pytest >= 8.0 |
+| **Config file** | none — discovered automatically |
+| **Quick run command** | `python -m pytest tests/test_script_generator.py -x -q` |
+| **Full suite command** | `python -m pytest tests/ -x -q` |
+| **Estimated runtime** | ~10 seconds |
+
+---
+
+## Sampling Rate
+
+- **After every task commit:** Run `python -m pytest tests/test_script_generator.py -x -q`
+- **After every plan wave:** Run `python -m pytest tests/ -x -q`
+- **Before `/gsd:verify-work`:** Full suite must be green
+- **Max feedback latency:** 10 seconds
+

+## Wave 0 Requirements
+
+- [ ] `tests/test_script_generator.py` — stubs for SCRPT-01 through SCRPT-05 (unit + integration)
+- [ ] `imptune/templates/scripts/install.ps1.j2` — Jinja2 template file
+- [ ] `imptune/templates/scripts/uninstall.ps1.j2` — Jinja2 template file
+- [ ] `imptune/templates/scripts/detect.ps1.j2` — Jinja2 template file
+- [ ] `imptune/generators/script_generator.py` — render functions
+- [ ] `imptune/api/scripts.py` — FastAPI router
+
+---
+
+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| Install script runs on real Windows endpoint via Intune | SCRPT-01 | Requires real Intune + endpoint | Deploy .intunewin package to test device, verify printer appears |
+| UAC elevation prompt appears for standard user | SCRPT-04 | Requires interactive desktop session | Run install.ps1 as standard user, verify UAC dialog |
+| WOW64 relaunch works in 32-bit PS | SCRPT-05 | Requires 32-bit PowerShell host | Launch powershell.exe (x86), run install.ps1, verify relaunch |
+
+---
+
+## 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
