# Phase 7 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | go test |
| **Config file** | none — existing infrastructure |
| **Quick run command** | `cd backend && go test ./...` |
| **Full suite command** | `cd backend && go test ./... && docker build -f backend/Dockerfile -t xtablo:test . && docker inspect xtablo:test` |
| **Estimated runtime** | ~30 seconds (tests); ~3 minutes (full with Docker build) |

---

## Sampling Rate

- **After every task commit:** Run `cd backend && go test ./...`
- **After every plan wave:** Run full suite including docker build validation
- **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 |
|---------|------|------|-------------|------------|-----------------|-----------|-------------------|-------------|--------|
| 7-01-01 | 01 | 0 | DEPLOY-04 | — | /healthz returns 200 with no DB; /readyz returns 503 when DB down | unit | `cd backend && go test ./internal/handlers/ -run TestHealthz` | ✅ | ⬜ pending |
| 7-01-02 | 01 | 0 | DEPLOY-01 | — | go:embed FS serves static assets correctly | unit | `cd backend && go test ./internal/static/` | ❌ W0 | ⬜ pending |
| 7-02-01 | 02 | 1 | DEPLOY-03 | — | goose.Up() runs migrations at startup without error | unit | `cd backend && go test ./cmd/web/ -run TestMigrations` | ❌ W0 | ⬜ pending |
| 7-03-01 | 03 | 2 | DEPLOY-01 | — | Docker image builds successfully with both binaries | manual | `docker build -f backend/Dockerfile -t xtablo:test . && docker run --rm xtablo:test /app/web --version` | ❌ W0 | ⬜ pending |
| 7-04-01 | 04 | 3 | DEPLOY-02 | — | docker-compose.prod.yaml starts all services without errors | manual | `docker compose -f backend/docker-compose.prod.yaml config` | ❌ W0 | ⬜ pending |
| 7-05-01 | 05 | 4 | DEPLOY-05 | — | README.md contains deploy, rollback, and incident sections | manual | `grep -c "## Deploy\|## Rollback\|## Incident" backend/README.md` | ✅ | ⬜ pending |

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

---

## Wave 0 Requirements

- [ ] Split `/healthz` into liveness-only (no DB ping) and create `/readyz` with DB ping — update `TestHealthz_OK` and `TestHealthz_Down`
- [ ] Create `backend/internal/assets/` package with `//go:embed` for static files
- [ ] Update `go.sum` with any new test dependencies

*Existing go test infrastructure covers all phase requirements.*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Docker image builds with templ generate | DEPLOY-01 | Requires Docker daemon; templ binary download in builder stage | `docker build -f backend/Dockerfile -t xtablo:test . --no-cache` — must complete without error |
| docker-compose.prod.yaml starts all services | DEPLOY-02 | Requires running Docker and Hetzner-like env setup | `docker compose -f backend/docker-compose.prod.yaml config` validates syntax; full start requires prod env vars |
| Caddy issues TLS cert and proxies to web | DEPLOY-02 | Requires real domain pointing to host; Let's Encrypt challenge | Manual: deploy to Hetzner VM, verify HTTPS works |
| goose.Up() runs migrations on prod startup | DEPLOY-03 | Requires live Postgres connection | Manual: check logs for "goose: migrating db" on first container start |
| /healthz returns 200 without DB | DEPLOY-04 | Unit test covers logic; integration requires deployed container | Manual: `curl https://your-domain.com/healthz` returns 200 |
| /readyz returns 503 when DB is down | DEPLOY-04 | Unit test covers logic; integration requires deployed container | Manual: stop postgres container, verify /readyz returns 503 |

---

## 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
