# Phase 6 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | Rust built-in `#[cfg(test)]` + `#[test]` |
| **Config file** | None — uses `cargo test` |
| **Quick run command** | `cargo test --lib -p app -- dashboard` |
| **Full suite command** | `cargo test --lib` |
| **Estimated runtime** | ~5 seconds |

---

## Sampling Rate

- **After every task commit:** Run `cargo test --lib -p app -- dashboard`
- **After every plan wave:** Run `cargo test --lib`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 5 seconds

## Wave 0 Requirements

Existing infrastructure covers all phase requirements. All 89 dashboard tests pass.

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Auto-focus TextInput on character key press | DISC-01 | Slint runtime focus behavior untestable in headless mode | 1. Open discovery mode 2. Type any letter 3. Verify TextInput gains focus and character appears |
| Flickable horizontal scroll of chip bar | DISC-06 | Visual scroll behavior requires rendered UI | 1. Add >5 status chips 2. Verify horizontal scroll works 3. Check no scrollbar chrome visible |
| Card-view transition animation | DISC-04/05 | Visual animation smoothness | 1. Select recipient/product tile 2. Verify smooth transition to filtered card view |

---

## 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 < 5s
- [x] `nyquist_compliant: true` set in frontmatter

**Approval:** approved 2026-03-11
