# Phase 16.1 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | cargo test (Rust) |
| **Config file** | Cargo.toml (workspace) |
| **Quick run command** | `cargo test --lib` |
| **Full suite command** | `cargo test --workspace` |
| **Estimated runtime** | ~30 seconds |

---

## Sampling Rate

- **After every task commit:** Run `cargo test --lib`
- **After every plan wave:** Run `cargo test --workspace`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 30 seconds

---

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| TBD | TBD | TBD | TBD | TBD | TBD | TBD | ⬜ pending |

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

*To be filled after plans are created.*

---

## Wave 0 Requirements

- [ ] Verify existing test suite passes before phase work begins
- [ ] Confirm V001 migration content (discord_user_id column presence)

*Existing test infrastructure covers framework needs.*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Pencil icon renders in Slint | UI glyph | Requires visual inspection | Build app, open popover, confirm pencil glyph visible |
| Avatar image displays on card | UI rendering | Requires visual inspection | Cache an avatar, confirm image replaces initials circle |
| Popover field order correct | UI layout | Requires visual inspection | Open popover, verify 7-field order matches CONTEXT.md |
| Settings Discord token section | UI layout | Requires visual inspection | Open Settings, verify token entry/validation/clear flow |

---

## 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
