# Phase 9 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | Bun test runner |
| **Config file** | none — existing infrastructure |
| **Quick run command** | `bun test` |
| **Full suite command** | `bun test` |
| **Estimated runtime** | ~5 seconds |

---

## Sampling Rate

- **After every task commit:** Run `bun test`
- **After every plan wave:** Run `bun test`
- **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 |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 09-01-01 | 01 | 1 | CLAS-01, CLAS-04 | unit | `bun test tests/services/setup.service.test.ts` | ❌ W0 | ⬜ pending |
| 09-01-02 | 01 | 1 | CLAS-03 | unit | `bun test tests/services/setup.service.test.ts` | ❌ W0 | ⬜ pending |
| 09-01-03 | 01 | 1 | CLAS-01 | route | `bun test tests/routes/setups.test.ts` | ❌ W0 | ⬜ pending |
| 09-02-01 | 02 | 2 | CLAS-02 | unit | `bun test tests/services/setup.service.test.ts` | ❌ W0 | ⬜ pending |
| 09-02-02 | 02 | 2 | VIZZ-01, VIZZ-02, VIZZ-03 | manual | N/A — visual component | N/A | ⬜ pending |

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

## Wave 0 Requirements

- [ ] `tests/services/setup.service.test.ts` — classification CRUD tests (service layer)
- [ ] `tests/routes/setups.test.ts` — classification API endpoint tests
- [ ] `tests/helpers/db.ts` — update CREATE TABLE for setup_items to include classification column

*Existing test infrastructure covers framework setup. Wave 0 adds phase-specific test files.*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Classification badge click-to-cycle | CLAS-01 | UI interaction, React component | Click badge on item card in setup, verify it cycles base→worn→consumable→base |
| Summary card weight subtotals | CLAS-02 | Visual layout verification | Add items to setup, classify some as worn/consumable, verify subtotals update |
| Donut chart renders with segments | VIZZ-01 | Recharts canvas/SVG rendering | Open setup with items, verify donut chart shows colored segments |
| Chart toggle category/classification | VIZZ-02 | UI interaction | Click pill toggle, verify chart segments change between category and classification views |
| Chart hover tooltips | VIZZ-03 | Hover interaction | Hover over donut segments, verify tooltip shows name, weight, percentage |

---

## 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
