# Phase 2 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | go test (stdlib) + testify v1.x assertions |
| **Config file** | none — existing from Phase 1 |
| **Quick run command** | `go test ./pkg/providers/... -short` |
| **Full suite command** | `go test ./... -v -count=1` |
| **Estimated runtime** | ~5 seconds |

---

## Sampling Rate

- **After every task commit:** Run `go test ./pkg/providers/... -short`
- **After every plan wave:** Run `go test ./... -v -count=1`
- **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 |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 02-01-01 | 01 | 1 | PROV-01 | unit | `go test ./pkg/providers/... -run TestTier1` | ✅ | ⬜ pending |
| 02-01-02 | 01 | 1 | PROV-02 | unit | `go test ./pkg/providers/... -run TestTier2` | ✅ | ⬜ pending |
| 02-02-01 | 02 | 1 | PROV-01,PROV-02 | integration | `go test ./pkg/engine/... -run TestScan` | ✅ | ⬜ pending |

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

---

## Wave 0 Requirements

Existing infrastructure covers all phase requirements — Phase 1 established go.mod, test framework, and testdata fixtures.

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| `keyhunter providers stats` shows 26 providers | PROV-01,PROV-02 | CLI output formatting | Run `go run . providers stats` and verify count shows 26+ |

---

## 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
