# Phase 1 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | dotnet test (built-in) |
| **Config file** | none — Wave 0 installs |
| **Quick run command** | `dotnet build` |
| **Full suite command** | `dotnet build && dotnet publish src/ChatAgent.Client/ChatAgent.Client.csproj` |
| **Estimated runtime** | ~15 seconds |

---

## Sampling Rate

- **After every task commit:** Run `dotnet build`
- **After every plan wave:** Run `dotnet build && dotnet publish src/ChatAgent.Client/ChatAgent.Client.csproj`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 15 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 01-01-01 | 01 | 1 | CODE-01 | build | `dotnet build` | ❌ W0 | ⬜ pending |
| 01-01-02 | 01 | 1 | CODE-01 | build | `dotnet build` | ❌ W0 | ⬜ pending |
| 01-02-01 | 02 | 1 | CODE-02 | build+run | `dotnet build && dotnet run --project src/ChatAgent.Api` | ❌ W0 | ⬜ pending |
| 01-02-02 | 02 | 2 | CODE-02 | publish | `dotnet publish src/ChatAgent.Client/ChatAgent.Client.csproj` | ❌ W0 | ⬜ pending |

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

---

## Wave 0 Requirements

- [ ] Solution and projects created via `dotnet new` commands
- [ ] All three projects buildable with `dotnet build`

*If none: "Existing infrastructure covers all phase requirements."*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| CORS working end-to-end | CODE-01 | Requires both projects running simultaneously | Start API, start Client, verify client can reach API endpoint |
| Tutorial comments present | CODE-02 | Content quality check | Review each file for inline Blazor concept explanations |

---

## 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 < 15s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
