## Quick Start for Developers

### Before Your Next Push

```bash
# 1. Test locally
./scripts/test-config-matrix.sh

# 2. If you see green checkmarks, you're good
# 3. Commit and push
git commit -m "feature: your change"
git push
```

### Testing Specific Configuration

```bash
./scripts/test-config-matrix.sh --config minimal
./scripts/test-config-matrix.sh --config full-ai --verbose
```

### Validate Flag Combination

```bash
./scripts/validate-cmake-config.sh \
  -DYAZE_ENABLE_GRPC=ON \
  -DYAZE_ENABLE_REMOTE_AUTOMATION=OFF  # This will warn!
```

## Testing Coverage

### Tier 1 (Every Commit - Standard CI)
```
✓ ci-linux      (gRPC + Agent CLI)
✓ ci-macos      (gRPC + Agent UI + Agent CLI)
✓ ci-windows    (gRPC core features)
```

### Tier 2 (Nightly - Feature Combinations)

**Linux** (6 configurations):
```
✓ minimal       - No AI, no gRPC (core functionality)
✓ grpc-only     - gRPC without automation
✓ full-ai       - All features enabled
✓ cli-no-grpc   - CLI only, no networking
✓ http-api      - REST endpoints
✓ no-json       - Ollama mode (no JSON parsing)
```

**macOS** (4 configurations):
```
✓ minimal       - GUI, no AI
✓ full-ai       - All features
✓ agent-ui      - Agent UI panels
✓ universal     - ARM64 + x86_64 binary
```

**Windows** (4 configurations):
```
✓ minimal       - No AI
✓ full-ai       - All features
✓ grpc-remote   - gRPC + remote automation
✓ z3ed-cli      - CLI executable
```

**Total**: 14 nightly configurations across 3 platforms

### Tier 3 (As Needed - Architecture-Specific)
```
• Windows ARM64 - Debug + Release
• macOS Universal - arm64 + x86_64
• Linux ARM - Cross-compile tests
```

## Configuration Problems Fixed

### 1. GRPC Without Automation
- **Symptom**: gRPC headers included but server never compiled
- **Status**: FIXED - CMake auto-enforces constraint
- **Test**: `grpc-only` config validates this

### 2. HTTP API Without CLI Stack
- **Symptom**: REST endpoints defined but no dispatcher
- **Status**: FIXED - CMake auto-enforces constraint
- **Test**: `http-api` config validates this

### 3. Agent UI Without GUI
- **Symptom**: ImGui panels in headless build
- **Status**: FIXED - CMake auto-enforces constraint
- **Test**: Local script tests this

### 4. AI Runtime Without JSON
- **Symptom**: Gemini service can't parse responses
- **Status**: DOCUMENTED - matrix tests edge case
- **Test**: `no-json` config validates degradation

### 5. Windows GRPC ABI Mismatch
- **Symptom**: Symbol errors with old gRPC on MSVC
- **Status**: FIXED - preset pins stable version
- **Test**: `ci-windows` validates version

### 6. macOS ARM64 Dependency Issues
- **Symptom**: Silent failures on ARM64 architecture
- **Status**: DOCUMENTED - `mac-uni` tests both
- **Test**: `universal` config validates both architectures

## Next Steps for Users

### Immediate (Today)

1. **Read the quick start**:
   ```bash
   cat docs/internal/testing/QUICKSTART.md
   ```

2. **Run local matrix tester**:
   ```bash
   ./scripts/test-config-matrix.sh
   ```

3. **Add to your workflow** (optional):
   ```bash
   # Before pushing:
   ./scripts/test-config-matrix.sh
   ```

### Near Term (This Week)

1. **Use validate-config before experimenting**:
   ```bash
   ./scripts/validate-cmake-config.sh -DYAZE_ENABLE_GRPC=ON ...
   ```

2. **Monitor nightly matrix tests**:
   - GitHub Actions > Configuration Matrix Testing
   - Check for any failing configurations

### Medium Term (This Month)

1. **Add matrix test to pre-commit hook** (optional):
   ```bash
   # In .git/hooks/pre-commit
   ./scripts/test-config-matrix.sh --smoke || exit 1
   ```

2. **Review and update documentation as needed**:
   - Add new configurations to `/docs/internal/configuration-matrix.md`
   - Update matrix test script when flags change

### Long Term

1. **Monitor for new problematic patterns**
2. **Consider Tier 3 testing when needed**
3. **Evaluate performance improvements per configuration**
4. **Plan future enhancements** (see MATRIX_TESTING_IMPLEMENTATION.md)

## Maintenance Responsibilities

### Weekly
- Check nightly matrix test results
- Alert if any configuration fails
- Review failure patterns

### Monthly
- Audit matrix configuration
- Check if new flags need testing
- Review binary size impact
- Update documentation as needed

### When Adding New CMake Flags
1. Update `cmake/options.cmake` (define + constraints)
2. Update `/docs/internal/configuration-matrix.md` (document + dependencies)
3. Add test config to `/scripts/test-config-matrix.sh`
4. Add matrix job to `/.github/workflows/matrix-test.yml`
5. Update validation rules in `/scripts/validate-cmake-config.sh`
