+## 2026-03-02: Test Suite Stabilization & Simulation Hardening
+*   **Track:** Test Suite Stabilization & Consolidation
+*   **Outcome:** Track Completed Successfully
+*   **Key Accomplishments:**
+    *   **Asyncio Lifecycle Fixes:** Eliminated pervasive Event loop is closed and coroutine was never awaited warnings in tests. Refactored conftest.py teardowns and test loop handling.
+    *   **Legacy Cleanup:** Completely removed gui_legacy.py and updated all 16 referencing test files to target gui_2.py, consolidating the architecture.
+    *   **Functional Assertions:** Replaced pytest.fail placeholders with actual functional assertions in pi_events, execution_engine, 	oken_usage, gent_capabilities, and gent_tools_wiring test suites.
+    *   **Simulation Hardening:** Addressed flakiness in 	est_extended_sims.py. Fixed timeouts and entry count regressions by forcing explicit GUI states (uto_add_history=True) during setup, and refactoring wait_for_ai_response to intelligently detect turn completions and tool execution stalls based on status transitions rather than just counting messages.
+    *   **Workflow Updates:** Updated conductor/workflow.md to establish a new rule forbidding full suite execution (pytest tests/) during verification to prevent long timeouts and threading access violations. Demanded batch-testing (max 4 files) instead.
+    *   **New Track Proposed:** Created sync_tool_execution_20260303 track to introduce concurrent background tool execution, reducing latency during AI research phases.
+*   **Challenges:** The extended simulation suite (	est_extended_sims.py) was highly sensitive to the exact transition timings of the mocked gemini_cli and the background threading of gui_2.py. Required multiple iterations of refinement to simulation/workflow_sim.py to achieve stable, deterministic execution. The full test suite run proved unstable due to accumulation of open threads/loops across 360+ tests, necessitating a shift to batch-testing.

+- [ ] Task: Refactor `mcp_client.py` for async execution
+    - [ ] WHERE: `mcp_client.py`
+    - [ ] WHAT: Convert tool execution wrappers to `async def` or wrap them in thread executors.
+    - [ ] HOW: Use `asyncio.to_thread` for blocking I/O bound tools.
+    - [ ] SAFETY: Ensure thread safety for shared resources.
+- [ ] Task: Update `ai_client.py` dispatcher
+    - [ ] WHERE: `ai_client.py` (around tool dispatch loop)
+    - [ ] WHAT: Use `asyncio.gather` to execute multiple tool calls concurrently.
+    - [ ] HOW: Await the gathered results before proceeding with the AI loop.

+# Track Specification: Asynchronous Tool Execution Engine (async_tool_execution_20260303)
+
+## Overview
+Currently, AI tool calls are executed synchronously in the background thread. If an AI requests multiple tool calls (e.g., parallel file reads or parallel grep searches), the execution engine blocks and runs them sequentially. This track will refactor the MCP tool dispatch system to execute independent tool calls concurrently using `asyncio.gather` or `ThreadPoolExecutor`, significantly reducing latency during the research phase.
+
+## Functional Requirements
+- **Concurrent Dispatch**: Refactor `ai_client.py` and `mcp_client.py` to support asynchronous execution of multiple parallel tool calls.
+- **Thread Safety**: Ensure that concurrent access to the file system or UI event queue does not cause race conditions.
+- **Cancellation**: If an AI request is cancelled (e.g., via user interruption), all running background tools should be safely cancelled.
+- **UI Progress Updates**: Ensure that the UI stream correctly reflects the progress of concurrent tools (e.g., "Tool 1 finished, Tool 2 still running...").
+
+## Non-Functional Requirements
+- Maintain complete parity with existing tool functionality.
+- Ensure all automated simulation tests continue to pass.
+
+## Acceptance Criteria
+- [ ] Multiple tool calls requested in a single AI turn are executed in parallel.
+- [ ] End-to-end latency for multi-tool requests is demonstrably reduced.
+- [ ] No threading deadlocks or race conditions are introduced.
+- [ ] All integration tests pass.

         -   For each remaining code file, verify a corresponding test file exists.
         -   If a test file is missing, you **must** create one. Before writing the test, **first, analyze other test files in the repository to determine the correct naming convention and testing style.** The new tests **must** validate the functionality described in this phase's tasks (`plan.md`).
 
-3.  **Execute Automated Tests with Proactive Debugging:**
-    -   Before execution, you **must** announce the exact shell command you will use to run the tests.
-    -   **Example Announcement:** "I will now run the automated test suite to verify the phase. **Command:** `CI=true npm test`"
+3.  **Execute Automated Tests in Batches:**
+    -   Because the full suite is large (>360 tests) and contains complex UI simulations, running the entire suite frequently can lead to random timeouts or threading access violations.
+    -   Before execution, you **must** announce the exact shell command.
+    -   **CRITICAL:** When verifying changes, **do not run the full suite (`pytest tests/`)**. Instead, run tests in small, targeted batches (maximum 4 test files at a time). Only use long timeouts (`--timeout=60` or `--timeout=120`) if the specific tests in the batch are known to be slow (e.g., simulation tests).
+    -   **Example Announcement:** "I will now run the automated test suite to verify the phase. **Command:** `uv run pytest tests/test_specific_feature.py`"
     -   Execute the announced command.
         - If tests fail with significant output (e.g., a large traceback), **DO NOT** attempt to read the raw `stderr` directly into your context. Instead, pipe the output to a log file and **spawn a Tier 4 QA Agent (`python scripts/mma_exec.py --role tier4-qa "[PROMPT]"`)** to summarize the failure.
         - You **must** inform the user and begin debugging using the QA Agent's summary. You may attempt to propose a fix a **maximum of two times**. If the tests still fail after your second proposed fix, you **must stop**, report the persistent failure, and ask the user for guidance.
