## Complete Workflow Example

### 1. Start Test Harness
```bash
./build-grpc-test/bin/yaze.app/Contents/MacOS/yaze \
  --enable_test_harness \
  --test_harness_port=50052 \
  --rom_file=assets/zelda3.sfc &
```

### 2. Automated GUI Testing (NEW)
```bash
# Click button
grpcurl -plaintext -import-path src/app/core/proto -proto imgui_test_harness.proto \
  -d '{"target":"button:Overworld","type":"LEFT"}' \
  127.0.0.1:50052 yaze.test.ImGuiTestHarness/Click

# Wait for window
grpcurl -plaintext -import-path src/app/core/proto -proto imgui_test_harness.proto \
  -d '{"condition":"window_visible:Overworld Editor","timeout_ms":5000}' \
  127.0.0.1:50052 yaze.test.ImGuiTestHarness/Wait

# Assert window visible
grpcurl -plaintext -import-path src/app/core/proto -proto imgui_test_harness.proto \
  -d '{"condition":"visible:Overworld Editor"}' \
  127.0.0.1:50052 yaze.test.ImGuiTestHarness/Assert
```

### 3. Run E2E Test Script (NEW)
```bash
./scripts/test_harness_e2e.sh
```

**Output**:
```
=== ImGuiTestHarness E2E Test ===

✓ Server started successfully

Test 1: Ping (Health Check)
✓ PASSED

Test 2: Click (Button)
✓ PASSED

Test 3: Type (Text Input)
✓ PASSED

Test 4: Wait (Window Visible)
✓ PASSED

Test 5: Assert (Window Visible)
✓ PASSED

=== Test Summary ===
Tests Run:    6
Tests Passed: 6
Tests Failed: 0

All tests passed!

## Active Priorities

### Priority 1: End-to-End Workflow Testing (Oct 3-4) 📋 NEXT
1. **Manual Testing**:
   - Start YAZE with test harness
   - Test all RPCs with real YAZE widgets
   - Validate error handling
   - Document edge cases

2. **Workflow Validation**:
   - Test complete workflows (Click → Wait → Assert)
   - Test text input workflows (Click → Type → Assert)
   - Test timeout scenarios
   - Test widget not found scenarios

### Priority 2: CLI Agent Integration (Oct 5-8)
1. **Create `z3ed agent test` Command**:
   - Parse natural language prompts
   - Generate RPC call sequences
   - Execute workflow via gRPC
   - Capture results and screenshots

2. **Example**:
   ```bash
   z3ed agent test --prompt "Open Overworld editor and verify it loads" \
     --rom zelda3.sfc
   
   # Generated workflow:
   # 1. Click "button:Overworld"
   # 2. Wait "window_visible:Overworld Editor" (5s)
   # 3. Assert "visible:Overworld Editor"
   # 4. Screenshot "full"
   ```

### Priority 3: Policy Evaluation Framework (Oct 9-12)
1. **YAML Policy Configuration**:
   - Define constraint schemas
   - Implement PolicyEvaluator service
   - Integrate with ProposalDrawer

2. **Policy Types**:
   - Change constraints (byte limits, allowed banks)
   - Test requirements (pass rate, coverage)
   - Review requirements (approval count)

---

## Known Limitations

### Non-Blocking Issues
1. **ProposalDrawer UX**:
   - No keyboard navigation
   - Large diffs truncated at 1000 lines

2. **Test Harness**:
   - Screenshot RPC not implemented
   - text_contains assertion uses placeholder
   - Windows/Linux testing pending

3. **Test Coverage**:
   - Need end-to-end workflow validation
   - Need real widget interaction testing

### Future Enhancements
1. Screenshot capture with image encoding
2. Advanced text retrieval for assertions
3. Keyboard shortcut automation
4. Recording/playback of test sequences

---
