+# 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 |
+|---------|------|------|-------------|-----------|-------------------|-------------|--------|

+| 36-01-02 | 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 |

+| 36-03-01 | 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
