# Phase 26 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | Bun test runner (built-in) |
| **Config file** | none — `bun test` auto-discovers `*.test.ts` |
| **Quick run command** | `bun test tests/services/discovery.service.test.ts tests/routes/discovery.test.ts` |
| **Full suite command** | `bun test` |
| **Estimated runtime** | ~15 seconds |

---

## Sampling Rate

- **After every task commit:** Run `bun test tests/services/discovery.service.test.ts tests/routes/discovery.test.ts`
- **After every plan wave:** Run `bun test`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 15 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 26-01-01 | 01 | 1 | DISC-02 | unit | `bun test tests/services/discovery.service.test.ts` | ❌ W0 | ⬜ pending |
| 26-01-02 | 01 | 1 | DISC-03 | unit | `bun test tests/services/discovery.service.test.ts` | ❌ W0 | ⬜ pending |
| 26-01-03 | 01 | 1 | DISC-04 | unit | `bun test tests/services/discovery.service.test.ts` | ❌ W0 | ⬜ pending |
| 26-01-04 | 01 | 1 | INFR-02 | unit | `bun test tests/services/discovery.service.test.ts` | ❌ W0 | ⬜ pending |
| 26-01-05 | 01 | 1 | DISC-02 | integration | `bun test tests/routes/discovery.test.ts` | ❌ W0 | ⬜ pending |
| 26-01-06 | 01 | 1 | DISC-03 | integration | `bun test tests/routes/discovery.test.ts` | ❌ W0 | ⬜ pending |

| 26-02-01 | 02 | 2 | DISC-01 | smoke | E2E only — overlay integration | ❌ E2E | ⬜ pending |
| 26-02-02 | 02 | 2 | DISC-05 | smoke | E2E only — requires auth session | ❌ E2E | ⬜ pending |

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

## Wave 0 Requirements

- [ ] `tests/services/discovery.service.test.ts` — stubs for DISC-02, DISC-03, DISC-04, INFR-02
- [ ] `tests/routes/discovery.test.ts` — stubs for DISC-02, DISC-03, DISC-04 route layer
- [ ] `src/server/services/discovery.service.ts` — new service file (stub)
- [ ] `src/server/routes/discovery.ts` — new route file (stub)

*Existing infrastructure covers test helpers (createTestDb, in-memory Postgres via PGlite).*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Hero search bar triggers CatalogSearchOverlay | DISC-01 | Client interaction; E2E pending rewrite (999.1) | Load `/`, click search bar, verify overlay opens |
| "Go to Collection" CTA visible for authenticated users | DISC-05 | Requires auth session; E2E pending rewrite | Log in, visit `/`, verify CTA present |
| "Go to Collection" CTA absent for anonymous | DISC-05 | Requires anonymous session | Open incognito, visit `/`, verify no CTA |

---

## 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 < 15s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
