# Phase 4 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | go test (stdlib) |
| **Config file** | go.mod (exists) |
| **Quick run command** | `go test ./...` |
| **Full suite command** | `go test -v -race ./...` |
| **Estimated runtime** | ~6 seconds |

---

## Sampling Rate

- **After every task commit:** Run `go test ./...`
- **After every plan wave:** Run `go test -v -race ./...`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 6 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 04-01-01 | 01 | 1 | NOTIF-01, NOTIF-02 | unit | `go test -run 'TestNotify\|TestFocus' ./...` | ❌ W0 | ⬜ pending |
| 04-01-02 | 01 | 1 | NOTIF-01, NOTIF-02 | unit | `go test -run 'TestDaemonNotify\|TestDaemonFocus' ./...` | ❌ W0 | ⬜ pending |
| 04-02-01 | 02 | 2 | I3-03 | unit | `go test -run 'TestFormatI3Bar' ./...` | ❌ W0 | ⬜ pending |
| 04-02-02 | 02 | 2 | I3-03 | build | `go build -o /dev/null ./...` | ✅ | ⬜ pending |

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

## Wave 0 Requirements

- [ ] Test stubs for notify, focus, i3bar formatting

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Dunst notification appears on Working→NeedsInput | NOTIF-01 | Requires real dunst + Claude session | Trigger tool_use permission, verify notification popup |
| Focus timer suppresses notifications | NOTIF-02 | Requires real notification stack | Run `vmux focus 1`, trigger transition, verify no popup |
| i3bar widget displays in i3 status bar | I3-03 | Requires real i3 config | Configure i3 status_command, verify widget appears |

---

## 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 < 6s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
