# Phase 36 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | vitest |
| **Config file** | server/vitest.config.ts |
| **Quick run command** | `pnpm --filter server test -- --run` |
| **Full suite command** | `pnpm --filter server test -- --run` |
| **Estimated runtime** | ~15 seconds |

---

## Sampling Rate

- **After every task commit:** Run `pnpm --filter server test -- --run`
- **After every plan wave:** Run `pnpm --filter server test -- --run`
- **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 |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 36-01-01 | 01 | 0 | VPIPE-04 | unit | `pnpm --filter server test -- --run voice-pipeline` | ❌ W0 | ⬜ pending |
| 36-01-02 | 01 | 1 | VPIPE-01 | unit | `pnpm --filter server test -- --run voice-pipeline` | ❌ W0 | ⬜ pending |
| 36-01-03 | 01 | 1 | VPIPE-02 | unit | `pnpm --filter server test -- --run voice-pipeline` | ❌ W0 | ⬜ pending |
| 36-02-01 | 02 | 1 | VPIPE-05 | unit | `pnpm --filter server test -- --run voice-pipeline` | ❌ W0 | ⬜ pending |
| 36-02-02 | 02 | 1 | VPIPE-06 | unit | `pnpm --filter server test -- --run voice-pipeline` | ❌ W0 | ⬜ pending |
| 36-03-01 | 03 | 2 | VPIPE-03 | integration | `pnpm --filter server test -- --run voice` | ❌ W0 | ⬜ pending |

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

## Wave 0 Requirements

- [ ] `server/src/services/__tests__/voice-pipeline.test.ts` — stubs for VPIPE-01, VPIPE-02, VPIPE-04
- [ ] `server/src/routes/__tests__/voice.test.ts` — stubs for VPIPE-03, VPIPE-05, VPIPE-06

*If none: "Existing infrastructure covers all phase requirements."*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Audio quality equal across WebM/OGG inputs | VPIPE-04 | Perceptual quality comparison | Record same phrase via browser and Telegram, compare transcription text |
| Voice-optimized prose sounds natural when read aloud | VPIPE-05 | Subjective speech quality | Read TTS-optimized output aloud, check for markdown artifacts |

---

## 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
