# Phase 8 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | ESLint + TypeScript strict + Next.js build (existing) |
| **Config file** | `eslint.config.mjs`, `tsconfig.json` |
| **Quick run command** | `cd packages/portal && npm run lint` |
| **Full suite command** | `cd packages/portal && npm run build` |
| **Estimated runtime** | ~45 seconds |

---

## Sampling Rate

- **After every task commit:** Run `npm run lint` in packages/portal
- **After every plan wave:** Run `npm run build` in packages/portal
- **Before `/gsd:verify-work`:** Full build must pass + Lighthouse PWA audit score >= 90
- **Max feedback latency:** 45 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 08-xx | 01 | 0 | MOB-04 | build | `npx next build` | ✅ | ⬜ pending |
| 08-xx | 02 | 1 | MOB-01,02 | build | `npx next build` | ✅ | ⬜ pending |
| 08-xx | 03 | 1 | MOB-03 | build | `npx next build` | ✅ | ⬜ pending |
| 08-xx | 04 | 2 | MOB-04,05 | build | `npx next build` | ✅ | ⬜ pending |
| 08-xx | 05 | 2 | MOB-06 | build | `npx next build` | ✅ | ⬜ pending |

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

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Pages render at 320px–1024px | MOB-01 | Device emulation | Chrome DevTools device mode, check all pages |
| Bottom tab bar on mobile | MOB-02 | Visual layout | Resize below 768px, verify tabs appear |
| Chat full-screen on mobile | MOB-03 | UI interaction | Tap conversation, verify full-screen with back arrow |
| PWA installable | MOB-04 | Browser behavior | Lighthouse PWA audit, manual install from Chrome |
| Push notification received | MOB-05 | Requires HTTPS + real device | Install PWA, send test message, verify notification |
| No hover-stuck interactions | MOB-06 | Touch device | Tap all buttons/links on real touch device |

## 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 < 45s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
