+## Code Quality & Architecture Notes
+
+### Async/Await Implementation
+- **Fully async throughout**: All I/O operations properly use async/await patterns
+- **FastAPI endpoints**: All endpoints that perform I/O are `async def` functions
+- **Discovery Engine integration**: Uses `ConversationalSearchServiceAsyncClient` correctly
+- **BigQuery integration**: Uses `asyncio.to_thread()` for non-blocking database operations
+- **Consistent patterns**: All async functions properly await their dependencies
+
+### Current Project Status (as of version 0.2.0)
+- **Documentation accuracy**: 95% accurate with modular structure
+- **Test coverage**: 94% overall, 100% for critical backend components (93/93 tests pass)
+- **Testing strategy**: Zero external dependencies with comprehensive auth mocking
+- **CI/CD maturity**: Split GitHub Actions workflow with automated semantic releases
+- **Architecture maturity**: Production-ready with enterprise security patterns
+- **Infrastructure**: Multi-regional Cloud Run deployment with Terraform IaC
+- **Dependencies**: Modern Python tooling with Poetry, up-to-date Google Cloud libraries
+- **Version automation**: Semantic release with automated badge updates and changelog generation
+
+### Key Configuration Files
+- **`pyproject.toml`**: Current version 0.2.0, Python 3.13+ requirement, comprehensive dependencies
+- **`src/answer_app/config.yaml`**: Application settings including preamble, regions, BigQuery tables
+- **`.streamlit/config.toml`**: Streamlit server configuration with dark theme and OAuth secrets path

+## Continuous Integration
+
+The project uses [GitHub Actions](../../.github/workflows/release.yml) for automated testing and releases with a split workflow design:
+
+### Workflow Structure
+
+- **Test Job**: Runs on all pushes and pull requests to `main` branch
+  - Executes full test suite
+  - Validates code quality and functionality
+  - No authentication required due to comprehensive mocking
+
+- **Release Job**: Runs only on pushes to `main` branch (not on PRs)
+  - Uses Python Semantic Release for automated versioning
+  - Prevents failed workflow runs on feature branch PRs
+  - Automatically generates changelogs and version bumps
+
+### Benefits
+
+- **Clean PR workflows**: No failed semantic-release runs on feature branches
+- **Consistent testing**: All tests pass without external dependencies
+- **Automated versioning**: Conventional commits trigger appropriate version bumps
+- **Zero maintenance**: No credential management needed for CI environment
+
