# Phase 9 — Validation Strategy

> Per-phase validation contract for feedback sampling during execution.

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | PowerShell verification scripts |
| **Config file** | none |
| **Quick run command** | `powershell -ExecutionPolicy Bypass -File scripts/verify_installer.ps1` |
| **Full suite command** | `powershell -ExecutionPolicy Bypass -File scripts/verify_installer.ps1` |
| **Estimated runtime** | ~2 seconds |

---

## Sampling Rate

- **After every task commit:** Run `powershell -ExecutionPolicy Bypass -File scripts/verify_installer.ps1`
- **After every plan wave:** Run full verification
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 2 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 09-01-01 | 01 | 1 | DIST-01 | build + artifact | `cmake --build build --config Release --target package` | yes | green |
| 09-01-02 | 01 | 1 | DIST-01 | artifact | `verify_installer.ps1` checks 1-14 | yes | green |
| 09-02-01 | 02 | 2 | DIST-01, DIST-02 | artifact | `verify_installer.ps1` full 14-check suite | yes | green |
| 09-02-02 | 02 | 2 | DIST-02 | manual | Hardware installer validation checkpoint | n/a | green |

---

## Wave 0 Requirements

Existing infrastructure covers all phase requirements. `scripts/verify_installer.ps1` provides 14 automated checks covering CMake target, git versioning, .iss script content (DLL, manifest, exclusions, SteamVR blocking, directory validation, cleanup, restoration, vrpathreg, uninstallable), and build output.

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Installer deploys to real Beyond driver directory | DIST-01 | Requires real Beyond driver installation | Run installer .exe, verify files at correct paths |
| vrpathreg registers nested driver | DIST-02 | Requires SteamVR runtime | Run installer, launch SteamVR, verify driver loads from nested path in vrserver log |

---

## Validation Sign-Off

- [x] All tasks have `<automated>` verify or Wave 0 dependencies
- [x] Sampling continuity: no 3 consecutive tasks without automated verify
- [x] Wave 0 covers all MISSING references
- [x] No watch-mode flags
- [x] Feedback latency < 2s
- [x] `nyquist_compliant: true` set in frontmatter

**Approval:** passed
