# Phase 16 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | go test |
| **Config file** | `backend/go.mod` |
| **Quick run command** | `go test ./backend/internal/web/... -run TestTablos` |
| **Full suite command** | `go test ./backend/internal/web/... -count=1` |
| **Estimated runtime** | ~5 seconds |

---

## Sampling Rate

- **After every task commit:** Run `go test ./backend/internal/web/... -run TestTablos`
- **After every plan wave:** Run `go test ./backend/internal/web/... -count=1`
- **Before `/gsd-verify-work`:** Full suite must be green
- **Max feedback latency:** 10 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Threat Ref | Secure Behavior | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|------------|-----------------|-----------|-------------------|-------------|--------|
| 16-01-01 | 01 | 1 | DETAIL-01 | — | N/A (template/CSS only) | build | `go build ./backend/...` | ✅ | ⬜ pending |
| 16-01-02 | 01 | 1 | DETAIL-02 | — | N/A | build | `go build ./backend/...` | ✅ | ⬜ pending |
| 16-02-01 | 02 | 2 | DETAIL-03 | — | N/A | unit | `go test ./backend/internal/web/... -run TestTablos -count=1` | ✅ | ⬜ pending |
| 16-02-02 | 02 | 2 | DETAIL-03 | — | N/A | build | `go build ./backend/...` | ✅ | ⬜ pending |
| 16-03-01 | 03 | 3 | DETAIL-02, DETAIL-03 | — | N/A | unit | `go test ./backend/internal/web/... -run TestTask -count=1` | ✅ | ⬜ pending |
| 16-03-02 | 03 | 3 | DETAIL-02, DETAIL-03 | — | N/A | build + unit | `go build ./backend/... && go test ./backend/internal/web/... -run TestTask -count=1` | ✅ | ⬜ pending |
| 16-04-01 | 04 | 3 | DETAIL-04 | — | N/A | unit | `go test ./backend/internal/web/... -run TestFilesTab -count=1` | ✅ | ⬜ pending |

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

## Wave 0 Requirements

Wave 0 is Plan 01 — SVG icon additions to `icon_button.templ` and CSS class additions to `app.css`. These are pure additive changes (no signature changes, no template wiring). No new test stubs are needed because handler tests only exercise routing and template rendering at the HTTP level; the new CSS classes and icon SVGs are not asserted in existing tests.

- [x] Baseline: `go test ./backend/internal/web/... -count=1` passes before any Phase 16 changes (confirmed by research)

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Tablo detail header renders project-card-top layout | DETAIL-01 | Visual/CSS — no automated assertion | Navigate to `/tablos/{id}`, verify title + avatar + action controls render as specified in UI-SPEC header contract |
| Kanban columns render horizontally with status grouping | DETAIL-02 | Visual layout | Open tablo with tasks in multiple statuses; verify 3 columns (Todo / In Progress / Done) render side by side |
| Etape group headers render with color dot | DETAIL-03 | Visual | Open tablo with etapes assigned to tasks; verify group header shows color dot + etape name |
| File table row actions (download, delete) respond | DETAIL-04 | HTMX interaction | Upload a file to a tablo; verify download link and delete button trigger correct HTMX responses |

---

## 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 < 10s
- [x] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
