# Phase 7 — 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_07_configuration.ps1` |
| **Full suite command** | `powershell -ExecutionPolicy Bypass -File scripts/verify_07_configuration.ps1` |
| **Estimated runtime** | ~5 seconds |

---

## Sampling Rate

- **After every task commit:** Run `powershell -ExecutionPolicy Bypass -File scripts/verify_07_configuration.ps1`
- **After every plan wave:** Run full verification
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 5 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 07-01-01 | 01 | 1 | CONF-01, CONF-02, CONF-03 | build + log | `cmake --build build --config Release` + vrserver log | yes | green |
| 07-02-01 | 02 | 1 | CONF-01..03 | log | `verify_07_configuration.ps1` full suite | yes | green |
| 07-02-02 | 02 | 1 | CONF-03 | manual | Hardware validation checkpoint | n/a | green |

---

## Wave 0 Requirements

Existing infrastructure covers all phase requirements. `scripts/verify_07_configuration.ps1` checks VRSettings reading, parameter clamping, status output extension, and default fallback values via vrserver log analysis.

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| User_trim change affects proximity sensitivity | CONF-03 | Requires physical headset + steamvr.vrsettings edit | Edit user_trim in vrsettings, restart SteamVR, verify sensitivity change |

---

## 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 < 5s
- [x] `nyquist_compliant: true` set in frontmatter

**Approval:** passed
