# Research Debrief: Temporal.io Python SDK Integration

## 1. Goals
The primary goal of this research project was to determine the correct procedure for integrating the Temporal.io Python SDK into our Bazel-based workspace and to establish a best-practice pattern for testing Temporal workflows and activities.

## 2. Execution Process & Key Decisions
The investigation followed these steps:
1.  **SDK Discovery**: A web search confirmed that `temporalio` is the official, modern Python SDK for Temporal.
2.  **Dependency Integration**: The `temporalio` package was added to the root `requirements.txt` file, and the `requirements.lock` file was regenerated to make the dependency available to Bazel under the `@pypi` hub.
3.  **Proof-of-Concept**: A small PoC was created in `experimental/temporal_python_prototype/` to verify the dependency could be correctly imported and used in a `py_binary` target. The PoC successfully demonstrated that the client could be initialized.
4.  **Testing Research**: A second web search revealed that `pytest` is the recommended framework for testing. The key testing utility is `temporalio.testing.WorkflowEnvironment`, which provides a time-skipping local server to test workflows without needing a live Temporal cluster. It also facilitates mocking activities to unit-test workflow logic in isolation.
5.  **Test Implementation**: A sample workflow and activity were added to the PoC. A corresponding `main_test.py` was created, which required adding `pytest-asyncio` to the project dependencies for handling async tests.
6.  **Troubleshooting**: The initial test run failed with an `ImportError: attempted relative import with no known parent package`. This was identified as a common issue when running Python tests with Bazel. The relative import (`from .main import ...`) was corrected to an absolute import from the workspace root (`from experimental.temporal_python_prototype.main import ...`), which resolved the issue.

## 3. Final Outcomes
*   A working, buildable proof-of-concept for the Temporal Python SDK now exists at `experimental/temporal_python_prototype/`.
*   A repeatable pattern for unit-testing Temporal workflows and activities using `pytest` and `WorkflowEnvironment` has been established and verified.

## 4. Actionable Insights & Key Learnings
*   **Official SDK**: The correct package is `temporalio`.
*   **Testing Dependencies**: Testing requires both `pytest` and `pytest-asyncio`.
*   **Critical Bazel Insight**: When writing `py_test` targets in Bazel, all imports must be absolute from the workspace root to avoid `ImportError`. Relative imports within the test files will fail. This is a crucial pattern to remember for all future Python testing with Bazel.

## 1. Goals
The primary goal of this project was to design, build, and harden a production-grade communication server for multi-agent collaboration. The key requirements were resilience, security, and scalability.

## 2. Execution Process & Key Decisions
The project was executed in several phases:
1.  **Initial Implementation**: A WebSocket server was built using `FastAPI` and `python-socketio`. Basic features for agent registration, agent discovery, and private messaging were implemented.
2.  **Resilience & Testing**: A comprehensive unit test suite was developed using `pytest`. During this phase, the server's error handling and message protocols were hardened.
3.  **Security Hardening**: A critical security vulnerability was addressed by implementing a mandatory token-based authentication system. Only clients presenting a valid shared secret in the `Authorization` header are allowed to connect. This phase also involved debugging and correcting a Bazel dependency configuration issue in `MODULE.bazel` where the `pip.parse` `hub_name` was misconfigured.
4.  **Scalability Research & Implementation**:
    *   The initial single-process architecture was identified as a major scalability bottleneck.
    *   A brief research detour was taken to investigate `Temporal.io` as a long-term solution for workflow orchestration. This resulted in a successful proof-of-concept for the `temporalio` Python SDK and a new, delegated project (`temporal_server_setup`) for deploying a development server.
    *   To unblock immediate progress, the project pivoted back to a Redis-based solution for scalability. The server was re-architected to use a `socketio.AsyncRedisManager`, decoupling state and allowing for horizontal scaling.
    *   The test suite was updated to use `fakeredis`, allowing for isolated and robust testing of the new Redis-based architecture.

## 3. Final Outcomes
*   A secure, scalable, and well-tested multi-agent communication server located at `servers/multi_agent_comm_server`.
*   The server is horizontally scalable via Redis and secured with token-based authentication.
*   A working proof-of-concept for `Temporal.io` integration now exists at `experimental/temporal_python_prototype/`, paving the way for future work.
*   A new project (`temporal_server_setup`) has been created and delegated to provide the necessary infrastructure for future Temporal-based development.

## 4. Actionable Insights & Key Learnings
*   **Bazel Python Dependencies**: The `hub_name` in `pip.parse` within `MODULE.bazel` is a critical setting that must be consistent with how dependencies are referenced in `BUILD.bazel` files (e.g., `@pypi//...`).
*   **Bazel Python Testing**: Imports within `py_test` targets must be absolute from the workspace root to avoid `ImportError`. This is a key pattern for future Python development in this workspace.
*   **Test-Driven Scalability**: The use of `fakeredis` proved highly effective for developing and testing the Redis-based scaling architecture without requiring a live Redis instance, demonstrating a powerful pattern for infrastructure-dependent development.
