# Phase 20 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | go test |
| **Config file** | none — existing test infrastructure |
| **Quick run command** | `go build ./...` |
| **Full suite command** | `TEST_DATABASE_URL='postgres://xtablo:xtablo@localhost:5432/xtablo?sslmode=disable' go test ./... -count=1` |
| **Estimated runtime** | ~20 seconds |

---

## Sampling Rate

- **After every task commit:** Run `go build ./...`
- **After every plan wave:** Run full suite with TEST_DATABASE_URL
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 20 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Threat Ref | Secure Behavior | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|------------|-----------------|-----------|-------------------|-------------|--------|
| 20-01-01 | 01 | 1 | DETAIL-01 | — | handler returns 404 for tablo not owned by current user | unit | `go build ./...` | ✅ | ⬜ pending |
| 20-01-02 | 01 | 1 | DETAIL-01 | — | N/A | unit | `go test ./backend/... -run TestTabloDetail -count=1` | ❌ W0 | ⬜ pending |
| 20-02-01 | 02 | 2 | TASK-01 | — | N/A | build | `just generate && go build ./...` | ✅ | ⬜ pending |
| 20-02-02 | 02 | 2 | TASK-01 | — | N/A | build | `just generate && go build ./...` | ✅ | ⬜ pending |
| 20-03-01 | 03 | 2 | DETAIL-01 | — | N/A | source | `grep -c "tablo-detail-header\|tablo-detail-title\|tablo-metadata-row\|tablo-progress-bar" backend/internal/web/ui/app.css` | ✅ | ⬜ pending |
| 20-03-02 | 03 | 2 | TASK-01 | — | N/A | source | `grep "background: var(--color-brand-primary)" backend/internal/web/ui/app.css` | ✅ | ⬜ pending |

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

---

## Wave 0 Requirements

- [ ] `backend/cmd/web/tablo_detail_test.go` — stubs for DETAIL-01, TASK-01 handler tests
- [ ] Test must compile with `go test ./... -run TestTabloDetail -count=1` returning 0 (skip OK)

*Existing infrastructure covers all other phase requirements (go build, just generate).*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Kanban drag-and-drop reorder persists after restyle | TASK-01 | Browser interaction required (Sortable.js) | Open /tablos/{id}, drag a task card to a different position in the same column, reload page and verify new position persists |
| Tablo detail header matches Figma visual | DETAIL-01 | Visual layout requires browser render | Open /tablos/{id}, compare header row (name, metadata, avatar stack, progress bar) against Board-1.png screenshot |
| Etapes section renders correctly | DETAIL-01 | Visual layout | Open /tablos/{id} that has etapes, verify etapes section is visible below kanban with correct French labels |

---

## Validation Sign-Off

- [x] All tasks have `<automated>` verify or Wave 0 dependencies
- [x] Sampling continuity: no 3 consecutive tasks without automated verify
- [x] Wave 0 covers all MISSING references
- [x] No watch-mode flags
- [x] Feedback latency < 20s
- [x] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
