# Phase 11 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | go test |
| **Config file** | none — standard Go test runner |
| **Quick run command** | `go test ./synth/... ./config/...` |
| **Full suite command** | `go test ./...` |
| **Estimated runtime** | ~10 seconds |

---

## Sampling Rate

- **After every task commit:** Run `go test ./synth/... ./config/...`
- **After every plan wave:** Run `go test ./...`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 10 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 11-01-01 | 01 | 1 | GRP-02 | unit | `go test ./synth/... -run TestAllClassesHaveConfig` | ✅ | ⬜ pending |
| 11-01-02 | 01 | 1 | GRP-02 | unit | `go test ./synth/... -run TestFrequenciesUnique` | ✅ | ⬜ pending |
| 11-02-01 | 02 | 2 | GRP-02 | unit | `go test ./config/... -run TestPrintConfig` | ✅ | ⬜ pending |
| 11-02-02 | 02 | 2 | GRP-03 | unit | `go test ./config/... -run TestLoad` | ✅ | ⬜ pending |

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

---

## Wave 0 Requirements

*Existing infrastructure covers all phase requirements. Test helpers already exist in synth and config packages.*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Family-coherent sound output | Success criteria 2 | Perceptual audio quality | Generate MP3 from representative pcap, listen for family grouping |

---

## 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
