# Phase 1 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | go test (stdlib) |
| **Config file** | none — Wave 0 creates go.mod + first test files |
| **Quick run command** | `go test ./...` |
| **Full suite command** | `go test -v -race ./...` |
| **Estimated runtime** | ~5 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:** 5 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 01-01-01 | 01 | 1 | DISC-01 | unit | `go test -run TestFindClaudeProcesses ./...` | ❌ W0 | ⬜ pending |
| 01-01-02 | 01 | 1 | DISC-02 | unit | `go test -run TestEncodePath ./...` | ❌ W0 | ⬜ pending |
| 01-01-03 | 01 | 1 | DISC-03 | unit | `go test -run TestEncodePath ./...` | ❌ W0 | ⬜ pending |
| 01-02-01 | 02 | 1 | STATE-01 | unit | `go test -run TestDetectState ./...` | ❌ W0 | ⬜ pending |
| 01-02-02 | 02 | 1 | STATE-02 | unit | `go test -run TestExtractPreview ./...` | ❌ W0 | ⬜ pending |

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

---

## Wave 0 Requirements

- [ ] `go.mod` — initialize Go module
- [ ] `shell.nix` / `.envrc` — NixOS dev environment
- [ ] `Makefile` — build/test/lint commands
- [ ] Test directory structure with initial stubs

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

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| `vmux list` shows all active sessions | DISC-01 | Requires multiple real Claude Code sessions running | Run 2+ claude sessions, run `vmux list`, verify all appear |
| State detection accuracy | STATE-01 | Requires sessions in different states | Have one session working, one idle, verify correct state display |

---

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

**Approval:** pending
