# Phase 14 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | bun test |
| **Config file** | none — uses bun built-in test runner |
| **Quick run command** | `bun test tests/` |
| **Full suite command** | `bun test tests/` |
| **Estimated runtime** | ~10 seconds |

---

## Sampling Rate

- **After every task commit:** Run `bun test tests/`
- **After every plan wave:** Run `bun test tests/`
- **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 |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| TBD | TBD | TBD | DB-01 | integration | `bun test tests/` | ❌ W0 | ⬜ pending |
| TBD | TBD | TBD | DB-02 | integration | `bun test tests/` | ❌ W0 | ⬜ pending |
| TBD | TBD | TBD | DB-03 | integration | `bun test tests/` | ❌ W0 | ⬜ pending |
| TBD | TBD | TBD | DB-04 | integration | `bun test tests/` | ❌ W0 | ⬜ pending |
| TBD | TBD | TBD | DB-05 | smoke | `docker compose -f docker-compose.dev.yml up -d` | ❌ W0 | ⬜ pending |

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

---

## Wave 0 Requirements

- [ ] `tests/helpers/db.ts` — Rewrite to use PGlite instead of bun:sqlite
- [ ] Existing test files updated from sync to async patterns

*Test infrastructure exists but needs migration from SQLite to PGlite.*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| SQLite data migration preserves all records | DB-04 | One-time script, not automatable in CI | Run migration script against test SQLite DB, verify row counts match |
| Docker Compose starts Postgres | DB-05 | Requires Docker runtime | Run `docker compose -f docker-compose.dev.yml up -d`, verify `pg_isready` |

---

## 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
