# Phase 04 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | vitest |
| **Config file** | apps/web/vitest.config.ts, apps/api/vitest.config.ts |
| **Quick run command** | `pnpm --filter @tessera/api test -- --run` |
| **Full suite command** | `pnpm test` |
| **Estimated runtime** | ~30 seconds |

---

## Sampling Rate

- **After every task commit:** Run `pnpm --filter @tessera/api test -- --run`
- **After every plan wave:** Run `pnpm test`
- **Before `/gsd-verify-work`:** Full suite must be green
- **Max feedback latency:** 30 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Threat Ref | Secure Behavior | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|------------|-----------------|-----------|-------------------|-------------|--------|
| 04-01-01 | 01 | 1 | MRKT-01 | — | N/A | integration | `pnpm --filter @tessera/api test` | ❌ W0 | ⬜ pending |
| 04-01-02 | 01 | 1 | MRKT-02 | T-04-01 | Admin-only activation | integration | `pnpm --filter @tessera/api test` | ❌ W0 | ⬜ pending |
| 04-02-01 | 02 | 1 | PRTAL-02 | — | N/A | e2e | browser check | ❌ W0 | ⬜ pending |
| 04-02-02 | 02 | 1 | PRTAL-03 | — | N/A | e2e | browser check | ❌ W0 | ⬜ pending |

| 04-03-02 | 03 | 2 | MRKT-04 | — | N/A | e2e | browser check | ❌ W0 | ⬜ pending |

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

## Wave 0 Requirements

- [ ] Test stubs for marketplace API endpoints
- [ ] Test stubs for sidebar navigation behavior

*Existing infrastructure covers framework setup — only test files needed.*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Marketplace grid layout responsive | MRKT-01 | Visual layout check | Open marketplace at 320px, 768px, 1024px widths |
| Sidebar module grouping by category | PRTAL-02 | Visual grouping check | Activate modules from different categories, verify sidebar groups |
| Module opens in main content area | PRTAL-03 | Navigation flow | Click module in sidebar, verify content renders in main area |

---

## 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 < 30s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
